df2052cc92 bochs: convert to drm_fb_helper_fbdev_setup/teardown
Currently unloading bochs_drm (after unbinding the vtconsole) results in
a warning about a leaked connector:

    [drm:drm_mode_config_cleanup] *ERROR* connector Virtual-3 leaked!

While investigating a potential fix I noticed that a lot of open-coded
functionality is already implemented elsewhere, so start converting it:
bochs_fbdev_init -> drm_fb_helper_fbdev_setup: trivial (similar impl).
bochs_fbdev_fini -> drm_fb_helper_fbdev_teardown: requires unembedding
"struct drm_framebuffer" from "struct bochs_framebuffer".

Unembedding drm_framebuffer is made easy using drm_gem_fbdev_fb_create
which can replace bochs_fbdev_destroy and custom routines in bochs_mm.c.
For this to work, the GEM object is moved into "drm_framebuffer". After
that, "bochs_framebuffer" is no longer needed and therefore removed.

Remove the unused "size" and "initialized" fields from fb, the latter is
not necessary as drm_fb_helper_fbdev_teardown can be called even if
bochsfb_create fails. This theory was tested by returning early and
late (just before drm_gem_fbdev_fb_create). Both scenarios fail
gracefully although the latter seems to leak the object from
bochsfb_create_object (not a regression).

Guess on the reason for the encoder leak: drm_framebuffer_cleanup was
previously used, but did not destroy much. drm_fb_helper_fbdev_teardown
is now used and calls drm_framebuffer_remove which does a bit more work.

Tested with 'echo 0 > /sys/class/vtconsole/vtcon1/bind; rmmod bochs_drm'
and also with Xorg + fbdev (startx -> xterm). The latter triggered a
warning in ttm_bo_vm_open that existed before, see

eae06120f1 drm: refuse ADDFB2 ioctl for broken bigendian drivers
Drivers must set the quirk_addfb_prefer_host_byte_order quirk to make
the drm_mode_addfb() compat code work correctly on bigendian machines.

If they don't they interpret pixel_format values incorrectly for bug
compatibility, which in turn implies the ADDFB2 ioctl does not work
correctly then.  So block it to make userspace fallback to ADDFB.

72fdb40c1a drm: extract drm_atomic_uapi.c
This leaves all the commit/check and state handling in drm_atomic.c,
while pulling all the uapi glue and the huge ioctl itself into a
seprate file.

This seems to almost perfectly split the rather big drm_atomic.c file
into 2 equal sizes.

Also adjust the kerneldoc and type a very terse overview text.

v2: Rebase.

v3: Fix tiny typo.

v4:
- Fixup armada, newly converted atomic driver hooray!
- Fixup msm/dpu1, newly added too.

Using the guc, we cannot disable the user interrupt generation as we use
it for driving submission. And from Icelake, we no longer have the
ability to individually mask interrupt generation from each engine,
disabling our ability to fake missed interrupts.

In both cases, report back to userspace that the missed interrupt
generator is no longer available.

drm/sun4i: tcon: Add dithering support for RGB565/RGB666 LCD panels
The hardware supports dithering on TCON channel 0 which is used for LCD
panels.

Dithering is a method of approximating a color from a mixture of other
colors when the required color isn't available. It reduces color
banding artifacts that can be observed when displaying gradients
(e.g. grayscale gradients). This may occur when the image that needs
to be displayed is 24-bit but the LCD panel is a lower bit depth and
does not perform dithering on its own.

drm/sun4i: tcon: Pass drm_encoder * into sun4i_tcon0_mode_set_cpu
sun4i_tcon0_mode_set_cpu() currently accepts struct mipi_dsi_device *
as its second parameter. This is derived from drm_encoder.

The DSI encoder is tied to the CPU interface mode of the TCON as a
special case. In theory, if hardware were available, we could also
support normal CPU interface modes. It is better to pass the generic
encoder instead of the specialized mipi_dsi_device, and handle the
differences inside the function.

Passing the encoder would also enable the function to pass it, or any
other data structures related to it, to other functions expecting it.
One such example would be dithering support that will be added in a
later patch, which looks at properties tied to the connector to
determine whether dithering should be enabled or not.

1f3eb3461f omapdrm changes for v4.20
Big amount of changes from Laurent, reworking the driver towards the

 of the operations on the display pipeline. The aim of this work is to
 allow omapdrm to use the common DRM panels and bridges.  Not all of the
 operations are dealt in these patches, so more work needs to be done.
 
 The only change visible to the user should be the change in module
 dependencies: e.g. earlier a panel module depended on an encoder module,
 but now the encoder module depends on the panel module, which affects
 the order in which to unload the modules.

d5986a1c4d drm/nouveau: Fix nouveau_connector_ddc_detect()
It looks like that when we moved over to using
drm_connector_for_each_possible_encoder() in nouveau, that one rather
important part of this function got dropped by accident:

	/*          Right   v   here */
	for (i = 0; nv_encoder = NULL, i < DRM_CONNECTOR_MAX_ENCODER; i++) {
		int id = connector->encoder_ids[i];
		if (id == 0)
			break;

Since it's rather difficult to notice: the conditional in this loop is
actually:

	nv_encoder = NULL, i < DRM_CONNECTOR_MAX_ENCODER

Meaning that all early breaks result in nv_encoder keeping it's value,
otherwise nv_encoder = NULL. Ugh.

Since this got dropped, nouveau_connector_ddc_detect() now returns an
encoder for every single connector, regardless of whether or not it's
detected:

    [ 1780.056185] nouveau 0000:01:00.0: DRM: DDC responded, but no EDID for DP-2

So: fix this to ensure we only return an encoder if we actually found
one, and clean up the rest of the function while we're at it since it's
nearly impossible to read properly.

Changes since v1:
- Don't skip ddc probing for LVDS if we can't switch DDC through
  vga-switcheroo, just do the DDC probing without calling
  vga_switcheroo_lock_ddc() - skeggsb

79e765ad66 drm/nouveau/drm/nouveau: Prevent handling ACPI HPD events too early
On most systems with ACPI hotplugging support, it seems that we always
receive a hotplug event once we re-enable EC interrupts even if the GPU
hasn't even been resumed yet.

This can cause problems since even though we schedule hpd_work to handle
connector reprobing for us, hpd_work synchronizes on
pm_runtime_get_sync() to wait until the device is ready to perform
reprobing. Since runtime suspend/resume callbacks are disabled before
the PM core calls ->suspend(), any calls to pm_runtime_get_sync() during
this period will grab a runtime PM ref and return immediately with
-EACCES. Because we schedule hpd_work from our ACPI HPD handler, and
hpd_work synchronizes on pm_runtime_get_sync(), this causes us to launch
a connector reprobe immediately even if the GPU isn't actually resumed
just yet. This causes various warnings in dmesg and occasionally, also
prevents some displays connected to the dedicated GPU from coming back
up after suspend. Example:

So, to fix this we attempt to grab a runtime PM reference in the ACPI
handler itself asynchronously. If the GPU is already awake (it will have
normal hotplugging at this point) or runtime PM callbacks are currently
disabled on the device, we drop our reference without updating the
autosuspend delay. We only schedule connector reprobes when we
successfully managed to queue up a resume request with our asynchronous
PM ref.

This also has the added benefit of preventing redundant connector
reprobes from ACPI while the GPU is runtime resumed!

fa3cdf8d0b drm/nouveau: Reset MST branching unit before enabling
When probing a new MST device, it's not safe to make any assumptions
about it's current state. While most well mannered MST hubs will just
disable the branching unit on hotplug disconnects, this isn't enough to
save us from various other scenarios that might have resulted in
something writing to the MST branching unit before we got control of it.
This could happen if a previous probe we tried failed, if we're booting
in kexec context and the hub is still in the state the last kernel put
it in, etc.

Luckily; there is no reason we can't just reset the branching unit
every time we enable a new topology. So, fix this by resetting it on
enabling new topologies to ensure that we always start off with a clean,
unmodified topology state on MST sinks.

This fixes occasional hard-lockups on my P50's laptop dock (e.g. AUX
times out all DPCD trasactions) observed after multiple docks, undocks,
and module reloads.

b26b4590dd drm/nouveau: Only write DP_MSTM_CTRL when needed
Currently, nouveau will re-write the DP_MSTM_CTRL register for an MST
hub every time it receives a long HPD pulse on DP. This isn't actually
necessary and additionally, has some unintended side effects.

With the P50 I've got here, rewriting DP_MSTM_CTRL constantly seems to
make it rather likely (1 out of 5 times usually) that bringing up MST
with it's ThinkPad dock will fail and result in sideband messages timing
out in the middle. Afterwards, successive probes don't manage to get the
dock to communicate properly over MST sideband properly.

Many times sideband message timeouts from MST hubs are indicative of
either the source or the sink dropping an ESI event, which can cause
DRM's perspective of the topology's current state to go out of sync with
reality. While it's tough to really know for sure what's happening to
the dock, using userspace tools to write to DP_MSTM_CTRL in the middle
of the MST link probing process does appear to make things flaky. It's
possible that when we write to DP_MSTM_CTRL, the function that gets
triggered to respond in the dock's firmware temporarily puts it in a
state where it might end up not reporting an ESI to the source, or ends
up dropping a sideband message we sent it.

So, to fix this we make it so that when probing an MST topology, we
respect it's current state. If the dock's already enabled, we simply
read DP_MSTM_CTRL and disable the topology if it's value is not what we
expected. Otherwise, we perform the normal MST probing dance. We avoid
taking any action except if the state of the MST topology actually
changes.

This fixes MST sideband message timeouts and detection failures on my
P50 with its ThinkPad dock.

3e1a12754d drm/nouveau: Fix deadlocks in nouveau_connector_detect()
When we disable hotplugging on the GPU, we need to be able to
synchronize with each connector's hotplug interrupt handler before the
interrupt is finally disabled. This can be a problem however, since
nouveau_connector_detect() currently grabs a runtime power reference
when handling connector probing. This will deadlock the runtime suspend
handler like so:

So: fix this by making it so that normal hotplug handling /only/ happens
so long as the GPU is currently awake without any pending runtime PM
requests. In the event that a hotplug occurs while the device is
suspending or resuming, we can simply defer our response until the GPU
is fully runtime resumed again.

Changes since v4:
- Use a new trick I came up with using pm_runtime_get() instead of the
  hackish junk we had before

6833fb1ec1 drm/nouveau/drm/nouveau: Use pm_runtime_get_noresume() in connector_detect()
It's true we can't resume the device from poll workers in
nouveau_connector_detect(). We can however, prevent the autosuspend
timer from elapsing immediately if it hasn't already without risking any
sort of deadlock with the runtime suspend/resume operations. So do that
instead of entirely avoiding grabbing a power reference.

7fec8f5379 drm/nouveau/drm/nouveau: Fix deadlock with fb_helper with async RPM requests
Currently, nouveau uses the generic drm_fb_helper_output_poll_changed()
function provided by DRM as it's output_poll_changed callback.
Unfortunately however, this function doesn't grab runtime PM references
early enough and even if it did-we can't block waiting for the device to
resume in output_poll_changed() since it's very likely that we'll need
to grab the fb_helper lock at some point during the runtime resume
process. This currently results in deadlocking like so:

[  246.775522] =============================================

After trying dozens of different solutions, I found one very simple one
that should also have the benefit of preventing us from having to fight
locking for the rest of our lives. So, we work around these deadlocks by
deferring all fbcon hotplug events that happen after the runtime suspend
process starts until after the device is resumed again.

Changes since v7:
 - Fixup commit message - Daniel Vetter

Changes since v6:
 - Remove unused nouveau_fbcon_hotplugged_in_suspend() - Ilia

Changes since v5:
 - Come up with the (hopefully final) solution for solving this dumb
   problem, one that is a lot less likely to cause issues with locking in
   the future. This should work around all deadlock conditions with fbcon
   brought up thus far.

Changes since v4:
 - Add nouveau_fbcon_hotplugged_in_suspend() to workaround deadlock
   condition that Lukas described
 - Just move all of this out of drm_fb_helper. It seems that other DRM
   drivers have already figured out other workarounds for this. If other
   drivers do end up needing this in the future, we can just move this
   back into drm_fb_helper again.

Changes since v3:
- Actually check if fb_helper is NULL in both new helpers
- Actually check drm_fbdev_emulation in both new helpers
- Don't fire off a fb_helper hotplug unconditionally; only do it if
  the following conditions are true (as otherwise, calling this in the
  wrong spot will cause Bad Things to happen):
  - fb_helper hotplug handling was actually inhibited previously
  - fb_helper actually has a delayed hotplug pending
  - fb_helper is actually bound
  - fb_helper is actually initialized
- Add __must_check to drm_fb_helper_suspend_hotplug(). There's no
  situation where a driver would actually want to use this without
  checking the return value, so enforce that
- Rewrite and clarify the documentation for both helpers.
- Make sure to return true in the drm_fb_helper_suspend_hotplug() stub
  that's provided in drm_fb_helper.h when CONFIG_DRM_FBDEV_EMULATION
  isn't enabled
- Actually grab the toplevel fb_helper lock in
  drm_fb_helper_resume_hotplug(), since it's possible other activity
  (such as a hotplug) could be going on at the same time the driver
  calls drm_fb_helper_resume_hotplug(). We need this to check whether or
  not drm_fb_helper_hotplug_event() needs to be called anyway

611ce85542 drm/nouveau: Remove duplicate poll_enable() in pmops_runtime_suspend()
Since actual hotplug notifications don't get disabled until
nouveau_display_fini() is called, all this will do is cause any hotplugs
that happen between this drm_kms_helper_poll_disable() call and the
actual hotplug disablement to potentially be dropped if ACPI isn't
around to help us.

d77ef138ff drm/nouveau/drm/nouveau: Fix bogus drm_kms_helper_poll_enable() placement
Turns out this part is my fault for not noticing when reviewing
9a2eba337c ("drm/nouveau: Fix drm poll_helper handling"). Currently
we call drm_kms_helper_poll_enable() from nouveau_display_hpd_work().
This makes basically no sense however, because that means we're calling
drm_kms_helper_poll_enable() every time we schedule the hotplug
detection work. This is also against the advice mentioned in
drm_kms_helper_poll_enable()'s documentation:

 Note that calls to enable and disable polling must be strictly ordered,
 which is automatically the case when they're only call from
 suspend/resume callbacks.

Of course, hotplugs can't really be ordered. They could even happen
immediately after we called drm_kms_helper_poll_disable() in
nouveau_display_fini(), which can lead to all sorts of issues.

Additionally; enabling polling /after/ we call
drm_helper_hpd_irq_event() could also mean that we'd miss a hotplug
event anyway, since drm_helper_hpd_irq_event() wouldn't bother trying to
probe connectors so long as polling is disabled.

So; simply move this back into nouveau_display_init() again. The race
condition that both of these patches attempted to work around has
already been fixed properly in

  d61a5c1063 ("drm/nouveau: Fix deadlock on runtime suspend")

70109354fe drm: Reject unknown legacy bpp and depth for drm_mode_addfb ioctl
Since this is handling user provided bpp and depth, we need to sanity
check and propagate the EINVAL back rather than assume what the insane
client intended and fill the logs with DRM_ERROR.

v2: Check both bpp and depth match the builtin pixel format, and
introduce a canonical DRM_FORMAT_INVALID to reserve 0 against any future
fourcc.

v3: Mark up DRM_FORMAT_C8 as being {bpp:8, depth:8}

6960e6da9c drm: fix drm_mode_addfb() on big endian machines.
Userspace on big endian machhines typically expects the ADDFB ioctl
returns a big endian framebuffer.  drm_mode_addfb() will call
drm_mode_addfb2() unconditionally with little endian DRM_FORMAT_*
values though, which is wrong.  This patch fixes that.

Drivers (both kernel and xorg) have quirks in place to deal with the
broken drm_mode_addfb() behavior.  Because of this we can't just change
drm_mode_addfb() behavior for everybody without breaking things.  Add
the quirk_addfb_prefer_host_byte_order field to mode_config, so drivers
can opt-in.

288f1ced5e drm/i915: Reduce context HW ID lifetime
Future gen reduce the number of bits we will have available to
differentiate between contexts, so reduce the lifetime of the ID
assignment from that of the context to its current active cycle (i.e.
only while it is pinned for use by the HW, will it have a constant ID).
This means that instead of a max of 2k allocated contexts (worst case
before fun with bit twiddling), we instead have a limit of 2k in flight
contexts (minus a few that have been pinned by the kernel or by perf).

To reduce the number of contexts id we require, we allocate a context id
on first and mark it as pinned for as long as the GEM context itself is,
that is we keep it pinned it while active on each engine. If we exhaust
our context id space, then we try to reclaim an id from an idle context.
In the extreme case where all context ids are pinned by active contexts,
we force the system to idle in order to recover ids.

We cannot reduce the scope of an HW-ID to an engine (allowing the same
gem_context to have different ids on each engine) as in the future we
will need to preassign an id before we know which engine the
context is being executed on.

v2: Improved commentary (Tvrtko) [I tried at least]

7948a2b158 qxl: fix null-pointer crash during suspend
"crtc->helper_private" is not initialized by the QXL driver and thus the

Fix this by converting the suspend/resume functions to use the

Tested system sleep with QEMU 3.0 using "echo mem > /sys/power/state".
During suspend the following message is visible from QEMU:

    spice/server/display-channel.c:2425:display_channel_validate_surface: canvas address is 0x7fd05da68308 for 0 (and is NULL)
    spice/server/display-channel.c:2426:display_channel_validate_surface: failed on 0

seem to work (tested with both the GTK and -spice options).

b212f0a470 drm/i915/icl: Fix context RPCS programming
There are two issues with the current RPCS programming for Icelake:

Expansion of the slice count bitfield has been missed, as well as the
required programming workaround for the subslice count bitfield size
limitation.

1)

Bitfield width for configuring the active slice count has grown so we need
to program the GEN8_R_PWR_CLK_STATE accordingly.

Current code was always requesting eight times the number of slices (due
writing to a bitfield starting three bits higher than it should). These
requests were luckily a) capped by the hardware to the available number of
slices, and b) we haven't yet exported the code to ask for reduced slice
configurations.

Due both of the above there was no impact from this incorrect programming
but we should still fix it.

2)

Due subslice count bitfield being only three bits wide and furthermore
capped to a maximum documented value of four, special programming
workaround is needed to enable more than four subslices.

With this programming driver has to consider the GT configuration as
2x4x8, while the hardware internally translates this to 1x8x8.

A limitation stemming from this is that either a subslice count between
one and four can be selected, or a subslice count equaling the total
number of subslices in all selected slices. In other words, odd subslice
counts greater than four are impossible, as are odd subslice counts
greater than a single slice subslice count.

This also had no impact in the current code base due breakage from 1)
always reqesting more than one slice.

While fixing this we also add some asserts to flag up any future bitfield
overflows.

v2:
 * Use a local in all branches for clarity. (Lionel)

06348d3086 drm/i915/ringbuffer: Move double invalidate to after pd flush
Continuing the fun of trying to find exactly the delay that is
sufficient to ensure that the page directory is fully loaded between
context switches, move the extra flush added in commit 70b73f9ac1
("drm/i915/ringbuffer: Delay after invalidating gen6+ xcs") to just
after we flush the pd. Entirely based on the empirical data of running
failing tests in a loop until we survive a day (before the mtbf is 10-30
minutes).

7ef4ac6ed9 drm/i915: Double check we didn't miss an unclaimed register access
Currently, if the user has enabled mmio-debug around each register
access, we presume that we have then checked them all. However, it is
still possible through omission (raw register access) or external
interaction that the unclaimed access was not highlighted.

0a1b60d76b drm/i915/gvt: Fix life cycle reference on KVM mm
Handle guest mm access life cycle properly with mmget()/mmput().
As noted by Linus, use_mm() depends on valid live page table but
KVM's mmgrab() doesn't guarantee that. As vGPU usage depends on
guest VM life cycle, need to make sure to use mmget()/mmput() to
guarantee VM address access.

v3: fix build

v2: v1 caused a weird dependence issue which failed for vfio
device release, which result invalid mdev vgpu and kvm state
without proper release taken. This trys to put right reference
around VM address space access instead.

d6acae363e drm/i915: Use a cached mapping for the physical HWS
Older gen use a physical address for the hardware status page, for which
we use cache-coherent writes. As the writes are into the cpu cache, we use
a normal WB mapped page to read the HWS, used for our seqno tracking.

Anecdotally, I observed lost breadcrumbs writes into the HWS on i965gm,
which so far have not reoccurred with this patch. How reliable that
evidence is remains to be seen.

v2: Explicitly pass the expected physical address to the hw
v3: Also remember the wild writes we once had for HWS above 4G.

3fbda31e81 drm/omap: Split mode fixup and mode set from encoder enable
The encoder enable operation currently performs mode fixup and mode
setting for all omap_dss_device instances in the display pipeline. There
are dedicated encoder operations for those operations (respectively
.atomic_check() and .mode_set()), but they are not used for this
purpose.

Move the mode fixup code to .atomic_check() and the mode set code
.mode_set() to better fit the KMS model. The bus flags fixup has to
happen at .mode_set() time as there is no place to store the bus flags
in the atomic state structures. This could be solved by extending one of
the state structures, but as the goal is to replace the fixup by direct
usage of bus flags through the driver, that would be pointless.

31cd7afa30 drm/omap: panels: Don't modify fixed timings
Panels drivers store their timings in a device data structure field that
is initialized at probe time, either from hardcoded values or from
firmware-supplied values. Those timings are then reported through the
.get_timings() operation to construct the panel display mode.

The panel timings are further modified by the .set_timings() operation,
which is called with the timings retrieved by .get_timings(), and
mangled by .check_timings(). The latter potentially adjusts the pixel
clock only.

Conceptually, modifying the panel timings is wrong, as the timings are
an intrinsic property of the panel and should thus be fixed.
Furthermore, modifying them this way at runtime can result in display
modes reported to userspace varying between calls, which is also wrong.

ca6e968b93 drm/omap: Remove .get_timings() operation from display connectors
The analog TV, DVI and HDMI connectors all report timing information
through the .get_timings() information.

For analog TV outputs the information is queried from the encoder, so
the operation is unused. Remove it.

For HDMI outputs the display pipeline provides EDID capability, so the
operation is unused as well. Remove it.

For DVI outputs the operation is also unused if the pipeline provides
EDID capability. Otherwise (when the DDC bus is not connected) we
shouldn't hardcode a single mode, but instead report no mode and let the
KMS core add default modes. This is achieved by removing the operation.

35d944cbee drm/omap: Query timing information from analog TV encoder
Timings for the TV output are currently reported by the analog TV
connector. This has the disadvantage of having to handle timing-related
operations in a connector omap_dss_device that has, at the hardware
level, no knowledge of any timing information.

Implement the .get_timings() operation in the venc driver, and get
timings from the first component in the pipeline that implements the
operatation. This switches the duty of reporting analog TV timings from
the connector to the encoder.

b4935e3a3c drm/omap: Store bus flags in the omap_dss_device structure
Source components in the display pipeline need to configure their output
signals polarities and clock driving edge based on the requirements of
the sink component.

Those requirements are currently shared across the whole pipeline in the
flags of a videomode structure, instead of being local to each bus. This
both prevents multiple buses from having different configurations (when
the hardware supports it), and makes it difficult to move from videomode
to drm_display_mode as the latter doesn't contain bus polarities and
clock edge flags.

Add a bus_flags field to the omap_dss_device structure and move the
DISPLAY_FLAGS_DE_(LOW|HIGH), DISPLAY_FLAGS_PIXDATA_(POS|NEG)EDGE and
DISPLAY_FLAGS_SYNC_(POS|NEG)EDGE videomode flags to bus_flags in all
external encoders, connectors and panels. The videomode flags are still
used internally for internal encoders, this will be addressed in a
second step.

The related videomode flags in the default mode of the DVI connector can
simply be dropped, as they are always overridden by the TFP410 driver.
Note that this results in both the DISPLAY_FLAGS_SYNC_POSEDGE and
DISPLAY_FLAGS_SYNC_NEGEDGE flags being set, which is invalid, but only
the former is tested for when programming the DISPC, so the DVI
connector flags are effectively overridden by the TFP410 flags.

18412b667c drm/omap: Merge HPD enable operation with HPD callback registration
The omap_dss_device .enable_hpd() and .disable_hpd() are used to enable
and disable hot-plug detection at omapdrm probe and remove time. This is
required to avoid reporting hot-plug detection events before the DRM
infrastructure is ready to accept them, as that could result in crashes
or other malfunction.

Hot-plug event reporting is conditioned by both HPD being enabled
through the .enable_hpd() operation and by the HPD callback being
registered though the .register_hpd_cb() operation. We thus don't need a
separate enable operation if we can guarantee that callbacks won't be
registered too early.

HPD callbacks are registered at connector initialization time, which is
too early to start reporting HPD events. There's however nothing
blocking a move of callback registration to a later time when the
omapdrm driver calls the HPD enable operations. Do so, and remove the
HPD enable operation completely from omap_dss_device drivers.

09e5bb6d5b drm/omap: dss: Add device operations flags
When an omap_dss_device operation can be implemented in multiple places
in a chain of devices, it is important to find out which device to
address to perfom the operation. This is currently done by calling the
operation on the display device at the end of the chain, and recursively
delagating the operation to the previous device if it can't be performed
locally. The drawback of this approach is an increased complexity in
omap_dss_device drivers.

In order to simplify the drivers, we will switch from a recursive model
to an interative model, centralizing the complexity in a single
location. This requires knowing which operations an omap_dss_device
supports at runtime. We can already test which operations are
implemented by checking the operation pointer, but implemented
operations can require resources whose availability varies between
systems. For instance a hot-plug signal from a connector can be wired to
a GPIO or to a bridge chip.

Add operation flags that can be set in the omap_dss_device structure by
drivers to signal support for operations.

DISPC channel assigned to it. As the channel is assigned to the output
by the output driver a failure there could only result from a driver
bug. All the output drivers have been verified and they are always
assigned a DISPC channel that is supported on the SoC they run on. The
check can thus be removed.

67dfd2d3d0 drm/omap: Remove omap_crtc_output global array
The omap_crtc_output global array is used to look up the DSS output
device by channel. We can replace that by accessing the output device
from the pipeline if we store the pipeline pointer in the omap_crtc
structure.

The global array is also used to protect against double connection of an
output. This can't happen with the connection handling mechanism going
from DSS outputs to displays. We can thus drop that check, allowing
removal of the global array.

There is no need to return an error from omapdss_device_disconnect()

that we can't prevent disconnection due to device unbinding (the return

drivers.

Extend the function and rename it to omapdss_of_find_connected_device()

Additionally, it is useful to differentiate between failures to return
the connected device because no link exists in the device tree for the
requested port, or because the connected device as described in the

and an error code in the second case, and update the callers

4e20bda68e drm/omap: dss: Replace omap_dss_device port number with bitmask
The omap_dss_device port_num field stores the DT port number associated
with the device. The field is used in different ways depending on the
device type:

- For DPI outputs, the port number is used as an identifier of the DPI
instance

- For sources, the port number is used to look up the omap_dss_device by
DT port node

As omap_dss_device instances are only looked up as sources by sinks,
setting the field to the number of the source port works for both use
cases.

However, to enable looking up sinks, we need to record all the ports
associated with an omap_dss_device. Do so by turning the port_num field
into an of_ports bitmask. For DPI outputs the port number is
additionally stored in the dpi_data structure as the output ID.

b93109d7dc drm/omap: dss: Move common device operations to common structure
The various types of omapdss_*_ops structures define multiple operations
that are not specific to a bus type. To simplify the code and remove
dependencies on specific bus types move those operations to a common
structure. Operations that are specific to a bus type are kept in the
specialized ops structures.

a7e82a67c1 drm/omap: dss: Rework output lookup by port node
The omap_dss_find_output_by_port_node() function defined in output.c
looks up an output from its port node. To do so it needs to call helper
functions from dss-of.c to lookup the port parent and the port number.
As omap_dss_find_output_by_port_node() is only called by
omapdss_of_find_source_for_first_ep() from dss-of.c this goes back and
forth between the to source files and isn't very clear.

Simplify the code by passing both the parent and the port number to
omap_dss_find_output_by_port_node() instead of the port node, and rename
the function to omap_dss_find_output_by_port().

a64f888749 drm/i915/intel_csr.c Fix DMC FW Loading issue on ICL.
This patch resolves the DMC FW loading issue.
Earlier DMC FW package have only one DMC FW for one stepping. But as such
there is no such restriction from Package side.
For ICL icl_dmc_ver1_07.bin binary package has DMC FW for 2 steppings.
So while reading the dmc_offset from package header, for 1st stepping
offset used to come 0x0 and was working fine till now.
But for second stepping and other steppings, offset is non zero number
and is in dwords. So we need to convert into bytes to fetch correct DMC
FW from correct place.

v2 : Added check for DMC FW max size for various gen. (Imre Deak)
v3 : Corrected naming convention for various gen. (Imre Deak)
v4 : Initialized max_fw_size to 0
v5 : Corrected DMC FW MAX_SIZE for various gen. (Imre Deak)
v6 : Fixed the typo issues.

The alternative would be to add this check in those drivers before
every drm_dp_cec call, but it makes sense to check it in the

4a47765103 drm/i915: Keep physical cursors pinned while in use
The optimisation inherent in commit 6a2c4232ec ("drm/i915: Make the
physical object coherent with GTT") relies on that once we allocated a
cursor we would have coherent, zero overhead access to the scanout plane
holding the cursor. That is we could then do the very frequent cursor
updates X enjoys with no indirection or kernel involvement. However,
that all hinges on the GGTT mmap of the cursor being pinned and not
require refaulting on each access -- handling such a page fault likely
requires the busy GGTT to be rearranged causing a stall. A very simple
fix is then to handle the physical cursor exactly like other cursors and
keep its vma pinned while active.

that the invalidation around a context/mm switch was insufficient (writes
would go astray). Adding a second MI_FLUSH_DW barrier prevents this, but
it is unclear as to whether this is merely a delaying tactic or if it is
truly serialising with the TLB invalidation. Either way, it is
empirically required.

First, we read from "vgdev->capsets[idx].max_size" before checking
whether "idx" is within bounds.  And secondly the bounds check is off by

Recent patch introduce strict check on scanning cmd:
Commit 8d458ea0ec ("drm/i915/gvt: return error on cmd access")

Before 8d458ea0ec, if cmd_reg_handler() checks that a cmd access a mmio
that not marked as F_CMD_ACCESS, it simply returns 0 and log an error.
Now it will return -EBADRQC which will cause the workload fail to submit.

On BXT, i915 applies WaClearHIZ_WM_CHICKEN3 which will program
GEN9_WM_CHICKEN3 by LRI when init wa ctx. If it has no F_CMD_ACCESS flag,
vgpu will fail to start. Also add F_MODE_MASK since it's mode mask reg.

c8ab5ac30c drm/i915/gvt: Make correct handling to vreg BXT_PHY_CTL_FAMILY
Guest kernel will write to BXT_PHY_CTL_FAMILY to reset DDI PHY
and pull BXT_PHY_CTL to check PHY status. Previous handling will
set/reset BXT_PHY_CTL of all PHYs at same time on receiving vreg
write to some BXT_PHY_CTL_FAMILY. If some BXT_PHY_CTL is already
enabled, following reset to another BXT_PHY_CTL_FAMILY will clear
the enabled BXT_PHY_CTL, which result in guest kernel print:

-----------------------------------
[drm:intel_ddi_get_hw_state [i915]]
*ERROR* Port B enabled but PHY powered down? (PHY_CTL 00000000)
-----------------------------------

The correct handling should operate BXT_PHY_CTL_FAMILY and
BXT_PHY_CTL on the same DDI.

v2: Use correct reg define. The naming looks confusing, however
    current i915_reg.h bind DPIO_PHY0 to _PHY_CTL_FAMILY_DDI and
    bind DPIO_PHY1 to _PHY_CTL_FAMILY_EDP, pairing to
    _BXT_PHY_CTL_DDI_A and _BXT_PHY_CTL_DDI_B respectively.
v3: v2 incorrectly map _PHY_CTL_FAMILY_EDP to _BXT_PHY_CTL_DDI_A.
    BXT_PHY_CTL() looks up DDI using PORTx but not PHYx. Based on
    DPIO_PHY to DDI mapping, make correct vreg handle to BXT_PHY_CTL
    on receiving vreg write to BXT_PHY_CTL_FAMILY. (He, Min)

299c2a904b drm/i915: Increase LSPCON timeout
100 ms is not enough time for the LSPCON adapter on Intel NUC devices to
settle. This causes dropped display modes at boot or screen reconfiguration.
Empirical testing can reproduce the error up to a timeout of 190 ms. Basic
boot and stress testing at 200 ms has not (yet) failed.

Increase timeout to 400 ms to get some margin of error.

Changes from v1:
The initial suggestion of 1000 ms was lowered due to concerns about delaying
valid timeout cases.
Update patch metadata.

f013027e26 drm/i915: Stop holding a ref to the ppgtt from each vma
The context owns both the ppgtt and the vma within it, and our activity
tracking on the context ensures that we do not release active ppgtt. As
the context fulfils our obligations for active memory tracking, we can
relinquish the reference from the vma.

This fixes a silly transient refleak from closed vma being kept alive
until the entire system was idle, keeping all vm alive as well.

9e4fa01221 drm/i915/execlists: Flush tasklet directly from reset-finish
On finishing the reset, the intention is to restart the GPU before we
relinquish the forcewake taken to handle the reset - the goal being the
GPU reloads a context before it is allowed to sleep. For this purpose,
we used tasklet_flush() which although it accomplished the goal of
restarting the GPU, carried with it a sting in its tail: it cleared the
TASKLET_STATE_SCHED bit. This meant that if another CPU queued a new
request to this engine, we would clear the flag and later attempt to
requeue the tasklet on the local CPU, breaking the per-cpu softirq
lists.

Remove the dangerous tasklet_kill() and just run the tasklet func
directly as we know it is safe to do so (the tasklets are internally
locked to allow mixed usage from direct submission).

29adeb4f95 drm/rockchip: Use struct_size() in devm_kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
	int stuff;
        void *entry[];
};

instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

or, like in this particular case:

size = sizeof(struct foo) + sizeof(void *) * count;
instance = devm_kzalloc(dev, size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = devm_kzalloc(dev, struct_size(instance, entry, count),
GFP_KERNEL);

This issue was detected with the help of Coccinelle.

d8c5d29f21 drm/i915: Don't check power domains state in intel_power_domains_init_hw()
During power domains initialization we acquire power well references for
power wells in the INIT power domain. The rest of power wells - which
BIOS could have left enabled - we can only acquire references as needed
during display HW readout and so must defer sanitization until then
(also implying that we must always do HW readout to cleanup unused power
wells).

Thus during initialization these latter power wells can have a refcount
of 0 while still being enabled. To avoid the false-positive state
mismatch error this causes remove the check from
intel_power_domains_init_hw() and rely on the state check in
intel_power_domains_enable() which follows the HW readout.

v2:
- Add comment to log and code clarifying how unused power wells get
  disabled. (Chris)

amdgpu_vm_bo_base_init, so won't called

4.amdgpu_vm_bo_map->amdgpu_vm_bo_insert_map, as the bo_base->moved is
not set true, the function amdgpu_vm_bo_insert_map will call
list_move(&bo_va->base.vm_status, &vm->moved)
5.amdgpu_cs_ioctl won't validate the swapout bo, as it is only in the

9bbf6a5341 drm/amd/display: Flatten unnecessary i2c functions
[Why]
The dce_i2c_hw code contained four funtcions that were only
called in one place and did not have a clearly delineated
purpose.

[How]
Inline these functions, keeping the same functionality.

This is not a functional change.

The functions disable_i2c_hw_engine and release_engine_dce_hw were
pulled into their respective callers.

The most interesting part of this change is the acquire functions.
dce_i2c_hw_engine_acquire_engine was pulled into
dce_i2c_engine_acquire_hw, and dce_i2c_engine_acquire_hw was pulled
into acquire_i2c_hw_engine.

Some notes to show that this change is not functional:
-Failure conditions in any function resulted in a cascade of calls that
ended in a 'return NULL'.
Those are replaced with a direct 'return NULL'.

-The variable result is the one from dce_i2c_hw_engine_acquire_engine.
The boolean result used as part of return logic was removed.

-As the second half of dce_i2c_hw_engine_acquire_engine is only executed
if that function is returning true and therefore exiting the do-while
loop in dce_i2c_engine_acquire_hw, those lines were moved outside
of the loop.

ad908423ef drm/amd/display: support 48 MHZ refclk off
[Why]
On PCO and up, whenever SMU receive message to indicate active
display count = 0. SMU will turn off 48MHZ TMDP reference clock
by writing to 1 TMDP_48M_Refclk_Driver_PWDN. Once this clock is
off, no PHY register will respond to register access. This means
our current sequence of notifying display count along with requesting
clock will cause driver to hang when accessing PHY registers after
displays count goes to 0.

[How]
Separate the PPSMC_MSG_SetDisplayCount message from the SMU messages
that request clocks, have display own sequencing of this message so
that we can send it at the appropriate time.
Do not redundantly power off HW when entering S3, S4, since display
should already be called to disable all streams. And ASIC soon be
powered down.

46659a83e4 drm/amd/display: Support reading hw state from debugfs file
[Why]

Logging hardware state can be done by triggering a write to the
debugfs file. It would also be useful to be able to read the hardware
state from the debugfs file to be able to generate a clean log without
timestamps.

[How]

Usage: cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log

Threading is an obvious concern when dealing with multiple debugfs
operations and blocking on global state in dm or dc seems unfavorable.

Adding an extra parameter for the debugfs log context state is the
implementation done here. Existing code that made use of DTN_INFO
and its associated macros needed to be refactored to support this.

We don't know the size of the log in advance so it reallocates the
log string dynamically. Once the log has been generated it's copied
into the user supplied buffer for the debugfs. This allows for seeking
support but it's worth nothing that unlike triggering output via
dmesg the hardware state might change in-between reads if your buffer
size is too small.

18e4aa33bd drm/amd/display: eliminate long wait between register polls on Maximus
[Why]
Now that we "scale" time delays correctly on Maximus (as of diags svn
r170115), the forced "35 ms" wait time now becomes 35 ms * 500 = 17.5
seconds, which is far too long.  Even having to repeat polling a
register once causes excessive delays on Maximus.

[How]
Just use the regular wait time passed to the generic_reg_wait()
function.  This is sufficient for Maximus now, and it also means that
there's one less "Maximus-only" code path in DAL.

Also disable the "REG_WAIT taking a while:" message on Maximus, since
things do take a while longer there and 1-2ms delays are not uncommon
(and nothing to worry about).

b6e075c3cb drm/atmel-hlcdc: support bus-width (12/16/18/24) in endpoint nodes
This beats the heuristic that the connector is involved in what format
should be output for cases where this fails.

E.g. if there is a bridge that changes format between the encoder and the
connector, or if some of the RGB pins between the lcd controller and the
encoder are not routed on the PCB.

This is critical for the devices that have the "conflicting output
formats" issue (SAM9N12, SAM9X5, SAMA5D3), since the most significant
RGB bits move around depending on the selected output mode. For
devices that do not have the "conflicting output formats" issue
(SAMA5D2, SAMA5D4), this is completely irrelevant.

But only if the highest pixel-clock frequency lower than requested
is significantly less accurate than the lowest frequency higher than
requested.

I pulled "10 times" as the discriminator out of the hat, and went with
that.

This is useful, if e.g. the target pixel-clock is 65MHz and the sys_clk
is 132MHz. In this case the highest possible pixel-clock lower than the
requested 65MHz is 52.8MHz, which is almost 20% off (and outside the
spec for the panel). The lowest possible pixel-clock higher than 65MHz
is 66MHz, which is a *much* better match, and only 1.5% off.

319711f982 drm/atmel-hlcdc: prefer a higher rate clock as pixel-clock base
If the divider used to get the pixel-clock is small, the granularity
of the frequencies possible for the pixel-clock is quite coarse. E.g.
requesting a pixel-clock of 65MHz with a sys_clk of 132MHz results
in the divider being set to 3 ending up with 44MHz.

By preferring the doubled sys_clk as base, the divider instead ends
up as 5 yielding a pixel-clock of 52.8Mhz, which is a definite
improvement.

While at it, clamp the divider so that it does not overflow in case
it gets big.

f921661bd4 drm/amdgpu: use bulk moves for efficient VM LRU handling (v6)
I continue to work for bulk moving that based on the proposal by Christian.

Background:
amdgpu driver will move all PD/PT and PerVM BOs into idle list. Then move all of
them on the end of LRU list one by one. Thus, that cause so many BOs moved to
the end of the LRU, and impact performance seriously.

Then Christian provided a workaround to not move PD/PT BOs on LRU with below
patch:
Commit 0bbf32026cf5ba41e9922b30e26e1bed1ecd38ae ("drm/amdgpu: band aid
validating VM PTs")

However, the final solution should bulk move all PD/PT and PerVM BOs on the LRU
instead of one by one.

Whenever amdgpu_vm_validate_pt_bos() is called and we have BOs which need to be
validated we move all BOs together to the end of the LRU without dropping the
lock for the LRU.

While doing so we note the beginning and end of this block in the LRU list.

Now when amdgpu_vm_validate_pt_bos() is called and we don't have anything to do,
we don't move every BO one by one, but instead cut the LRU list into pieces so
that we bulk move everything to the end in just one operation.

+--------------+-----------------+-----------+---------------------------------------+

After test them with above three benchmarks include vulkan and opencl. We can
see the visible improvement than original, and even better than original with
workaround.

v2: move all BOs include idle, relocated, and moved list to the end of LRU and
put them together.
v3: remove unused parameter and use list_for_each_entry instead of the one with
save entry.
v4: move the amdgpu_vm_move_to_lru_tail after command submission, at that time,
all bo will be back on idle list.
v5: remove amdgpu_vm_move_to_lru_tail_by_list(), use bulk_moveable instread of
validated, and move ttm_bo_bulk_move_lru_tail() also into
amdgpu_vm_move_to_lru_tail().
v6: clean up and fix return value.

d82f99422b drm/amd/display: move edp fast boot optimization flag to stream
[Why]
During S4/S3 stress test it is possible to resume from S4 without
calling mode set on eDP, meaning high level optimization flag is not
reset. If this is followed by an S3 resume call, driver will see
optimization flag is set and consume it and think backend is powered
on when in fact it is not.

This results in PHY being off in sequence where
S4->Resume->S3->Resume->ApplyOpt->black screen.

[How]
Move optimization flag to stream instead of a DC flag.

72ac71a7e6 drm/amd/display: HDR dynamic meta should be treated as stream update
[Why]
Recently we fixed HDR static meta using AFMT registers to be treated as
fast stream update.
Dynamic meta is still being treated as (full) surface update because it
touches HUBP and it travels with pipe data.
Here we change it to be (fast) stream update.
Note, originally we also wanted to redesign here a bit, but without OS
level support for true dynamic meta, it's left the same. We are simply
using HW that can do dynamic meta to send HDR static meta, I still prefer
keeping it in one static meta type then defining dynamic meta types to
hold the same info. Once we know how OS interfaces look like, we can
do proper design.

[How]
Move dyn meta update from update_hubp_dpp to commit_planes_do_stream_update

[Why]
Vesa DPMS tool sends different HDR meta in OS flips without changing output
parameters. We don't properly update HDR info frame:
- we label HDR meta update as fast update
- when updating HW info frame, we only do it if full update

[How]
It should still be fast update, so when doing HW infoframe update,
do it always no matter the update type.
Also, don't request passive flip for HDR meta update only without output
transfer function or color space changed.

Disable shall be done via timer of 2 seconds regardless of ramping
complete or not, just to simplify.

Also, ramp to mid instead of min, due to better flicker performance...

9410a3776b drm/amd/display: fix LFC tearing at top of screen
Tearing occurred because new VTOTAL MIN/MAX was being programmed
too early.
The flip can happen within the VUPDATE high region, and the new min/max
would take effect immediately. But this means that frame is not variable
anymore, and tearing would occur when the flip actually happens.

The fixed insert duration should be programmed on the first VUPDATE
interrupt instead.

050790cc59 drm/amd/display: Fix bug that causes black screen
Ignore MSA bit on DP display is usually set during SetTimings, but
there was a case where the module thought refresh rate was not valid
and ignore MSA bit was not set.

Later, a valid refresh rate range was requested but since ignore MSA bit
not set, it caused black screen.

Issue if with how the module checked for VRR support. Fix up that logic.
DM should call new valid_range function to determine if timing is supported.

5a83c93249 drm/amd/display: Add support for toggling DFS bypass
[Why]

If the hardware supports DFS bypass it will always be enabled after
creation of the DCCG. DFS bypass should only be enabled when
the current stream consists of a single embedded panel and the
minimum display clock is below the DFS bypass threshold.

[How]

Add a function to the DCCG table that updates the DFS bypass state
when setting the bandwidth. If the DFS bypass state is changed, the
clock needs to be reprogrammed to reflect this before the DPREFCLK
is updated for audio endpoints. The existing display clock value
is used as the target display clock value when reprogramming since the
resulting change will be equal or larger to the current value.

These changes only specifically target dce110 but do offer a framework
for support on other applicable targets.

Note: This option was actually reset to false anyway for most of

While there is support for using and quering DFS bypass clocks the
hardware is never notified to enter DFS bypass mode for dce110.

[How]

Add a flag that can be set when programming the display engine PLL
to enable DFS bypass mode. If this flag is set then the hardware is
notified to enter DFS bypass mode and the correct display engine clock
frequency can be acquired.

bf1178c989 drm/bridge: ti-sn65dsi86: Add mystery delay to enable()
This patch adds a 70ms mystery delay to the bridge driver in enable.
By experimentation, it seems like it can go anywhere up until we
initiate semi-auto link training. If we don't have the delay, link
training fails.

I tried to root cause this as best I could, but neither the datasheet
for the panel nor the bridge mention a delay of this magnitude in their
timing requirements. So for now, add the mystery delay until someone
figures out a better fix.

Changes in v3:
- Added to the set

It makes the secondary AOC E2460P monitor connected via DP to an

99da0b3539 drm/i915: WARN() if we can't lookup_power_well()
None of the current lookup_power_well() callers are actually checking
for NULL return values, they all just use the pointer right away.  The
first idea was to replace these theoretical segfaults with a BUG()
since this would at least make our code a little more explicit to the
reader. It was suggested that just converting the BUG() to a WARN()
and returning any power well would probably be better since it would
still keep the system running while at the same time exposing the
driver bug.

We can only hit this NULL/BUG()/WARN() condition if we try to lookup a
power well that isn't defined on a given platform. If that ever
happens, we have to fix our code, making it lookup the correct power
well. Because of this, I don't think it's worth trying to implement
error checking in every caller. Improving our CI system will be a
better use of our time once a bug is found in the wild.

v2: Avoid the BUG() with a WARN() return a random PW (Michal).

39d1e234e1 drm/i915/icl: implement the tc/legacy HPD {dis,}connect flows
Unlike the other ports, TC ports are not available to use as soon as
we get a hotplug. The TC PHYs can be shared between multiple
controllers: display, USB, etc. As a result, handshaking through FIA
is required around connect and disconnect to cleanly transfer
ownership with the controller and set the type-C power state.

This patch implements the flow sequences described by our
specification. We opt to grab ownership of the ports as soon as we get
the hotplugs in order to simplify the interactions and avoid surprises
in the user space side. We may consider changing this in the future,
once we improve our testing capabilities on this area.

v2:
 * This unifies the DP and HDMI patches so we can discuss everything
   at once so people looking at random single patches can actually
   understand the direction.
 * I found out the spec was updated a while ago. There's a small
   difference in the connect flow and the patch was updated for that.
 * Our spec also now gives a good explanation on what is really
   happening. As a result, comments were added.
 * Add some more comments as requested by Rodrigo (Rodrigo).
v3:
 * Downgrade a DRM_ERROR that shouldn't ever happen but we can't act
   on in case it does (Chris).

BSpec: 21750, 4250.

a5ec8332d4 drm: Add per-plane pixel blend mode property
Pixel blend modes represent the alpha blending equation
selection, describing how the pixels from the current
plane are composited with the background.

Adds a pixel_blend_mode to drm_plane_state and a
blend_mode_property to drm_plane, and related support
functions.

Defines three blend modes in drm_blend.h.

Changes since v1:
 - Moves the blending equation into the DOC comment
 - Refines the comments of drm_plane_create_blend_mode_property to not
   enumerate the #defines, but instead the string values
 - Uses fg.* instead of pixel.* and plane_alpha instead of plane.alpha
Changes since v2:
 - Refines the comments of drm_plane_create_blend_mode_property:
      1) Puts the descriptions (after the ":") on a new line
      2) Adds explaining why @supported_modes need PREMUL as default
Changes since v3:
 - Refines drm_plane_create_blend_mode_property(). drm_property_add_enum()
   can calculate the index itself just fine, so no point in having the
   caller pass it in.
 - Since the current DRM assumption is that alpha is premultiplied
   as default, define DRM_MODE_BLEND_PREMULTI as 0 will be better.
 - Refines some comments.
Changes since v4:
 - Adds comments in drm_blend.h.
 - Removes setting default value in drm_plane_create_blend_mode_property()
   as it is already in __drm_atomic_helper_plane_reset().
 - Fixes to use state->pixel_blend_mode instead of using
   plane->state->pixel_blend_mode in reset function.
 - Rebases on drm-misc-next.

drm/sun4i: tcon-top: Use struct_size() in devm_kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
	int stuff;
        void *entry[];
};

instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);

This issue was detected with the help of Coccinelle.

0edf681375 drivers/gpu/drm/gma500/: change return type to vm_fault_t
Use new return type vm_fault_t for fault handler.  For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno.  Once all instances are converted, vm_fault_t will become a
distinct type.

Ref-> 1c8f422059 ("mm: change return type to vm_fault_t")

Previously vm_insert_{pfn,mixed} returns err which driver mapped into
VM_FAULT_* type.  The new function vmf_insert_{pfn,mixed} will replace
this inefficiency by returning VM_FAULT_* type.

vmf_error() is the newly introduce inline function in 4.17-rc6.

a61d904fd6 drm/i915: Simplify condition to keep DMC active during S0ix
For S0ix we want to deinit power domains (and so deactivate the DMC
firmware) exactly when the platform supports the DC9 state. To reach
S0ix we need DC9 on these platforms (for which the DMC FW needs to be
deactivated) while to reach S0ix on the rest of the DMC platforms we
need DC6 (which needs the DMC FW to stay active).

Simplify the condition accordingly so it will be automatically
correct for upcoming DC9 platforms like ICL.

815f0ddb34 include/linux/compiler*.h: make compiler-*.h mutually exclusive
Commit cafa0010cd ("Raise the minimum required gcc version to 4.6")
recently exposed a brittle part of the build for supporting non-gcc
compilers.

Both Clang and ICC define __GNUC__, __GNUC_MINOR__, and
__GNUC_PATCHLEVEL__ for quick compatibility with code bases that haven't
added compiler specific checks for __clang__ or __INTEL_COMPILER.

This is brittle, as they happened to get compatibility by posing as a
certain version of GCC.  This broke when upgrading the minimal version
of GCC required to build the kernel, to a version above what ICC and
Clang claim to be.

Rather than always including compiler-gcc.h then undefining or
redefining macros in compiler-intel.h or compiler-clang.h, let's
separate out the compiler specific macro definitions into mutually
exclusive headers, do more proper compiler detection, and keep shared
definitions in compiler_types.h.

Fixes: cafa0010cd ("Raise the minimum required gcc version to 4.6")

e296de926d drm/syncobj: Drop add/remove_callback from driver interface
This is used for handling future fences. Currently no driver use
these, and I think given the new timeline fence proposed by KHR it
would be better to have a more abstract interface for future fences.
Could be something simple like a struct dma_future_fence plus a
function to add a callback or wait for the fence to materialize.

Then syncobj (and anything else really) could grow new functions to
expose these two drivers. Normal dma_fence would then keep the nice
guarantee that they will always signal (and through ordering, be
deadlock free). dma_future_fence would then be the tricky one.

This also fixes sphinx complaining about the kerneldoc.

93065ac753 mm, oom: distinguish blockable mode for mmu notifiers
There are several blockable mmu notifiers which might sleep in
mmu_notifier_invalidate_range_start and that is a problem for the
oom_reaper because it needs to guarantee a forward progress so it cannot
depend on any sleepable locks.

Currently we simply back off and mark an oom victim with blockable mmu
notifiers as done after a short sleep.  That can result in selecting a new
oom victim prematurely because the previous one still hasn't torn its
memory down yet.

We can do much better though.  Even if mmu notifiers use sleepable locks
there is no reason to automatically assume those locks are held.  Moreover
majority of notifiers only care about a portion of the address space and
there is absolutely zero reason to fail when we are unmapping an unrelated
range.  Many notifiers do really block and wait for HW which is harder to
handle and we have to bail out though.

This patch handles the low hanging fruit.
__mmu_notifier_invalidate_range_start gets a blockable flag and callbacks
are not allowed to sleep if the flag is set to false.  This is achieved by
using trylock instead of the sleepable lock for most callbacks and
continue as long as we do not block down the call chain.

I think we can improve that even further because there is a common pattern
to do a range lookup first and then do something about that.  The first
part can be done without a sleeping lock in most cases AFAICS.

The oom_reaper end then simply retries if there is at least one notifier
which couldn't make any progress in !blockable mode.  A retry loop is
already implemented to wait for the mmap_sem and this is basically the
same thing.

The simplest way for driver developers to test this code path is to wrap
userspace code which uses these notifiers into a memcg and set the hard
limit to hit the oom.  This can be done e.g.  after the test faults in all
the mmu notifier managed memory and set the hard limit to something really
small.  Then we are looking for a proper process tear down.

c76abab59b drm: Use horizontal and vertical chroma subsampling factor while calculating offsets in the physical address of framebuffer
For multi-planar formats, while calculating offsets in planes with index greater than 0
(ie second plane, third plane, etc), one needs to divide (src_x * cpp) with horizontal
chroma subsampling factor and (src_y * pitch) with vertical chroma subsampling factor.

The reason being that the planes contain subsampled (ie reduced) data (by a factor of 2) and thus
while calculating the byte position coresponding to the x and y co-ordinates, one needs to
divide it with the sampling factor.

59f1c8ab30 drm/i915: Increase LSPCON timeout
100 ms is not enough time for the LSPCON adapter on Intel NUC devices to
settle. This causes dropped display modes at boot or screen reconfiguration.
Empirical testing can reproduce the error up to a timeout of 190 ms. Basic
boot and stress testing at 200 ms has not (yet) failed.

Increase timeout to 400 ms to get some margin of error.

Changes from v1:
The initial suggestion of 1000 ms was lowered due to concerns about delaying
valid timeout cases.
Update patch metadata.

6dfc4a8f13 drm/i915: Verify power domains after enabling them
After
commit 2cd9a689e9 ("drm/i915: Refactor intel_display_set_init_power() logic")
it makes more sense to check the power domain/well refcounts after
enabling the power domains functionality. Before that it's guaranteed
that most power wells (in the INIT domain) will have a reference held,
so not an interesting state.

While at it also add the check after the init_hw/fini_hw, disable and
suspend/resume steps. Make the test optional on a Kconfig option since
it may add substantial overhead: on VLV/CHV the corresponding PUNIT reg
access for each power well may take up to 20ms.

v2:
- Add the state check to more spots. (Chris)

v3:
- During suspend check the state before deiniting display core.
  Afterwards DC states are disabled (and so the dc_off power well is
  enabled) even though we don't hold a reference on it.
- Do the test conditionally based on a new Kconfig option. (Chris)

d5acba26bf Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
 
 There is a lot here, much more than normal, seems like everyone is
 writing new driver subsystems these days...  Anyway, major things here
 are:
 	- new FSI driver subsystem, yet-another-powerpc low-level
 	  hardware bus
 	- gnss, finally an in-kernel GPS subsystem to try to tame all of
 	  the crazy out-of-tree drivers that have been floating around
 	  for years, combined with some really hacky userspace
 	  implementations.  This is only for GNSS receivers, but you
 	  have to start somewhere, and this is great to see.
 Other than that, there are new slimbus drivers, new coresight drivers,
 new fpga drivers, and loads of DT bindings for all of these and existing
 drivers.
 
 Full details of everything is in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

An optional follow-on PR for 4.19, on top of previous -fixes PR, which
brings in a6xx support.

These patches have been on list since earlier in the year (mostly
waiting for userspace).  They have been in linux-next since earlier in
the week, now that we have freedreno userspace working on a6xx[1][2].
So far glmark2, Chromium/ChromiumOS, gnome-shell, glamor, xonotic,
etc, are working.  And a healthy chuck of deqp works, and I've been
busy fixing things.  The needed libdrm changes (no new uapi changes
needed) are already on master, and the 2nd branch is rebased on that.

dce888798d drm/i915: remove confusing GPIO vs PCH_GPIO
Instead of defining all registers twice, define just a PCH_GPIO_BASE
that has the same address as PCH_GPIO_A and use that to calculate all
the others. This also brings VLV and !HAS_GMCH_DISPLAY in line, doing
the same thing.

v2: Fix GMBUS registers to be relative to gpio base; create GPIO()
    macro to return a particular gpio address and move the enum out of
    i915_reg.h (suggested by Jani)

v3: Move base offset inside the GPIO() macro so the GMBUS defines don't
    actually need to be changed (suggested by Daniel/Ville)

v4: Move definition of i915_gpio to intel_display.h and remove
    GMBUS/GPIO handling from gvt since now they have their own
    defines.

We can not use depends since the driver configuration uses select,

The device global init_power_on flag is somewhat arbitrary and makes
debugging power refcounting problems difficult. Instead arrange things
so that all display power domain get has a corresponding put call. After
this change we have the following sequences:

driver loading:
intel_power_domains_init_hw();
<other init steps>
intel_power_domains_enable();

driver unloading:
intel_power_domains_disable();
<other uninit steps>
intel_power_domains_fini_hw();

system suspend:
intel_power_domains_disable();
<other suspend steps>
intel_power_domains_suspend();

system resume:
intel_power_domains_resume();
<other resume steps>
intel_power_domains_enable();

at other times while the driver is loaded:
intel_display_power_get();
...
intel_display_power_put();

Currently, we cancel the extra wakeref we have for !runtime-pm devices
inside power_wells_fini_hw. However, this is not strictly paired with
the acquisition of that wakeref in runtime_pm_enable (as the fini_hw may
be called on errors paths before we even call runtime_pm_enable). Make
the symmetry more explicit and include a check that we do release all of
our rpm wakerefs.

a4417b7b41 drm/i915: Stop holding a ref to the ppgtt from each vma
The context owns both the ppgtt and the vma within it, and our activity
tracking on the context ensures that we do not release active ppgtt. As
the context fulfils our obligations for active memory tracking, we can
relinquish the reference from the vma.

This fixes a silly transient refleak from closed vma being kept alive
until the entire system was idle, keeping all vm alive as well.

6209c285e7 drm/i915: set DP Main Stream Attribute for color range on DDI platforms
Since Haswell we have no color range indication either in the pipe or
port registers for DP. Instead, there's a separate register for setting
the DP Main Stream Attributes (MSA) directly. The MSA register
definition makes no references to colorimetry, just a vague reference to
the DP spec. The connection to the color range was lost.

Apparently we've failed to set the proper MSA bit for limited, or CEA,
range ever since the first DDI platforms. We've started setting other
MSA parameters since commit dae847991a ("drm/i915: add
intel_ddi_set_pipe_settings").

Without the crucial bit of information, the DP sink has no way of
knowing the source is actually transmitting limited range RGB, leading
to "washed out" colors. With the colorimetry information, compliant
sinks should be able to handle the limited range properly. Native
(i.e. non-LSPCON) HDMI was not affected because we do pass the color
range via AVI infoframes.

Though not the root cause, the problem was made worse for DDI platforms
with commit 55bc60db59 ("drm/i915: Add "Automatic" mode for the
"Broadcast RGB" property"), which selects limited range RGB
automatically based on the mode, as per the DP, HDMI and CEA specs.

After all these years, the fix boils down to flipping one bit.

[Per testing reports, this fixes DP sinks, but not the LSPCON. My
 educated guess is that the LSPCON fails to turn the CEA range MSA into
 AVI infoframes for HDMI.]

3af71f649d drm/i915: Restore user forcewake domains across suspend
On suspend, we cancel the automatic forcewake and clear all other sources
of forcewake so the machine can sleep before we do suspend. However, we
expose the forcewake to userspace (only via debugfs, but nevertheless we
do) and want to restore that upon resume or else our accounting will be
off and we may not acquire the forcewake before we use it. So record
which domains we cleared on suspend and reacquire them early on resume.

341a15bb91 drm/i915: Unmask user interrupts writes into HWSP on snb/ivb/vlv/hsw
An oddity occurs on Sandybridge, Ivybridge and Haswell (and presumably
Valleyview) in that for the period following the GPU restart after a
reset, there are no GT interrupts received. From Ville's notes, bit 0 in
the HWSTAM corresponds to the render interrupt, and if we unmask it we
do see immediate resumption of GT interrupt delivery (via the master irq
handler) after the reset.

ad3c776b17 drm/i915: Fix PM refcounting w/o DMC firmware
The case where the firmware isn't specified for a platform (although
runtime PM works only with DMC on this platform) is the same case where
the firmware is specified but can't be loaded for some reason. Hence we
need to get a display init power domain ref in the first case too to
keep the refcount bookkeeping in balance.

Also convert the related log message to be a debug one, since it's a
valid scenario for a new platform, where we need to have
dev_info->has_csr=1 set, but add support for actually loading the
firmware only later.

v2:
- In addition to the debug log, WARN on non-alpha support platforms,
  since then the first case isn't valid scenario. (Chris)

If we pardon a per-engine reset, we may leave the STOP_RING bit asserted
in RING_MI_MODE resulting in the engine hanging. Unconditionally clear
it on the per-engine exit path as we know that either we skipped the
reset and so need the cancellation, or the reset was successful and the
cancellation is a no-op, or there was an error and we will follow up
with a full-reset or wedging (both of which will stop the engines again
as required).

958f338e96 Merge branch 'l1tf-final' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Merge L1 Terminal Fault fixes from Thomas Gleixner:
 "L1TF, aka L1 Terminal Fault, is yet another speculative hardware
  engineering trainwreck. It's a hardware vulnerability which allows
  unprivileged speculative access to data which is available in the
  Level 1 Data Cache when the page table entry controlling the virtual
  address, which is used for the access, has the Present bit cleared or
  other reserved bits set.

  If an instruction accesses a virtual address for which the relevant
  page table entry (PTE) has the Present bit cleared or other reserved
  bits set, then speculative execution ignores the invalid PTE and loads
  the referenced data if it is present in the Level 1 Data Cache, as if
  the page referenced by the address bits in the PTE was still present
  and accessible.

  While this is a purely speculative mechanism and the instruction will
  raise a page fault when it is retired eventually, the pure act of
  loading the data and making it available to other speculative
  instructions opens up the opportunity for side channel attacks to
  unprivileged malicious code, similar to the Meltdown attack.

  While Meltdown breaks the user space to kernel space protection, L1TF
  allows to attack any physical memory address in the system and the
  attack works across all protection domains. It allows an attack of SGX
  and also works from inside virtual machines because the speculation
  bypasses the extended page table (EPT) protection mechanism.

  The assoicated CVEs are: CVE-2018-3615, CVE-2018-3620, CVE-2018-3646

  The mitigations provided by this pull request include:

   - Host side protection by inverting the upper address bits of a non
     present page table entry so the entry points to uncacheable memory.

   - Hypervisor protection by flushing L1 Data Cache on VMENTER.

   - SMT (HyperThreading) control knobs, which allow to 'turn off' SMT
     by offlining the sibling CPU threads. The knobs are available on
     the kernel command line and at runtime via sysfs

   - Control knobs for the hypervisor mitigation, related to L1D flush
     and SMT control. The knobs are available on the kernel command line
     and at runtime via sysfs

   - Extensive documentation about L1TF including various degrees of
     mitigations.

  Thanks to all people who have contributed to this in various ways -
  patches, review, testing, backporting - and the fruitful, sometimes
  heated, but at the end constructive discussions.

  There is work in progress to provide other forms of mitigations, which
  might be less horrible performance wise for a particular kind of
  workloads, but this is not yet ready for consumption due to their
  complexity and limitations"

08ea70a417 drm/i915: Disable runtime-pm using lowlevel functions if !HAS_RC6
If we cannot setup rc6, we cannot let the GPU suspend itself as it
cannot save its state (to a powercontext). As such, we must disable
runtime-pm, but we should do so using the low-level pm-runtime function
which leaves our own debugging functions intact (and continue to detect
errors in our runtime-pm handling should we ever be able to enable rc6).

dc5977da99 drm/i915: set DP Main Stream Attribute for color range on DDI platforms
Since Haswell we have no color range indication either in the pipe or
port registers for DP. Instead, there's a separate register for setting
the DP Main Stream Attributes (MSA) directly. The MSA register
definition makes no references to colorimetry, just a vague reference to
the DP spec. The connection to the color range was lost.

Apparently we've failed to set the proper MSA bit for limited, or CEA,
range ever since the first DDI platforms. We've started setting other
MSA parameters since commit dae847991a ("drm/i915: add
intel_ddi_set_pipe_settings").

Without the crucial bit of information, the DP sink has no way of
knowing the source is actually transmitting limited range RGB, leading
to "washed out" colors. With the colorimetry information, compliant
sinks should be able to handle the limited range properly. Native
(i.e. non-LSPCON) HDMI was not affected because we do pass the color
range via AVI infoframes.

Though not the root cause, the problem was made worse for DDI platforms
with commit 55bc60db59 ("drm/i915: Add "Automatic" mode for the
"Broadcast RGB" property"), which selects limited range RGB
automatically based on the mode, as per the DP, HDMI and CEA specs.

After all these years, the fix boils down to flipping one bit.

[Per testing reports, this fixes DP sinks, but not the LSPCON. My
 educated guess is that the LSPCON fails to turn the CEA range MSA into
 AVI infoframes for HDMI.]

d6fee0dee0 drm/i915: Kick waiters on resetting legacy rings
This reapplies commit 39f3be162c ("drm/i915: Kick waiters on resetting
legacy rings") after the improved gem_eio was run across all machines we
found that gen3 and early gen4 still lost the immediate interrupt
following reset, and the HWSTAM w/a applied to gen6+ is inadequate.

Unlike the later gen, on gen3/4 the principle (and only tests to fail so
far) are the wait vs reset test cases, whereas the reset stress case
works fine (which was the predominantly failing case for gen6+). That is
enough to suggest the underlying issue is sufficiently different to
support the difference in HWSTAM efficacy.

potential spectre issue 'vgpu->vdev.region' [r]

Fix this by sanitizing info.index before indirectly using it to index
vgpu->vdev.region

Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

patch initializes the mutex in vgpu create operation to avoid the problem.

a66b4cd1e7 Merge branch 'work.open3' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs open-related updates from Al Viro:

 - "do we need fput() or put_filp()" rules are gone - it's always fput()
   now. We keep track of that state where it belongs - in ->f_mode.

 - int *opened mess killed - in finish_open(), in ->atomic_open()
   instances and in fs/namei.c code around do_last()/lookup_open()/atomic_open().

 - alloc_file() wrappers with saner calling conventions are introduced
   (alloc_file_clone() and alloc_file_pseudo()); callers converted, with
   much simplification.

 - while we are at it, saner calling conventions for path_init() and
   link_path_walk(), simplifying things inside fs/namei.c (both on
   open-related paths and elsewhere).

* 'work.open3' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (40 commits)
  few more cleanups of link_path_walk() callers
  allow link_path_walk() to take ERR_PTR()
  make path_init() unconditionally paired with terminate_walk()
  document alloc_file() changes
  make alloc_file() static
  do_shmat(): grab shp->shm_file earlier, switch to alloc_file_clone()
  new helper: alloc_file_clone()
  create_pipe_files(): switch the first allocation to alloc_file_pseudo()
  anon_inode_getfile(): switch to alloc_file_pseudo()

dddc0557e3 drm/amd/display: Guard against null crtc in CRC IRQ
[Why]

A null pointer deference can occur if crtc is null in
amdgpu_dm_crtc_handle_crc_irq. This can happen if get_crtc_by_otg_inst
returns NULL during dm_crtc_high_irq, leading to a hang in some IGT
test cases.

[How]

Check that CRTC is non-null before accessing its fields.

f4e60c5cfb drm/i915: Force reset on unready engine
If engine reports that it is not ready for reset, we
give up. Evidence shows that forcing a per engine reset
on an engine which is not reporting to be ready for reset,
can bring it back into a working order. There is risk that
we corrupt the context image currently executing on that
engine. But that is a risk worth taking as if we unblock
the engine, we prevent a whole device wedging in a case
of full gpu reset.

Reset individual engine even if it reports that it is not
prepared for reset, but only if we aim for full gpu reset
and not on first reset attempt.

v2: force reset only on later attempts, readability (Chris)
v3: simplify with adequate caffeine levels (Chris)

41db645a33 drm/i915: Bump priority of clean up work
We require that we keep the list of outstanding work short so that we do
not "leak" memory while pageflipping under stress. However that system
stress may delay kernel workers virtually indefinitely, which incurs the
pageflips stall and eventually hit a timeout waiting for the cleanup.

Try to combat CPU starvation of our short-lived cleanup workers by
switching to a high priority workqueue.

Some workloads may be prepared in vgpu's queue but not be scheduled
to run yet. If vgpu is released at this time, they will not be freed
in workload complete callback and so need to be freed in vgpu release

Add new vgpu_release operation in gvt_ops to stop vgpu and release

vgpu.

c44301fce6 drm/i915: Allow control of PSR at runtime through debugfs, v6
Currently tests modify i915.enable_psr and then do a modeset cycle
to change PSR. We can write a value to i915_edp_psr_debug to force
a certain PSR mode without a modeset.

To retain compatibility with older userspace, we also still allow
the override through the module parameter, and add some tracking
to check whether a debugfs mode is specified.

Changes since v1:
- Rename dev_priv->psr.enabled to .dp, and .hw_configured to .enabled.
- Fix i915_psr_debugfs_mode to match the writes to debugfs.
- Rename __i915_edp_psr_write to intel_psr_set_debugfs_mode, simplify
  it and move it to intel_psr.c. This keeps all internals in intel_psr.c
- Perform an interruptible wait for hw completion outside of the psr
  lock, instead of being forced to trywait and return -EBUSY.
Changes since v2:
- Rebase on top of intel_psr changes.
Changes since v3:
- Assign psr.dp during init. (dhnkrn)
- Add prepared bool, which should be used instead of relying on psr.dp. (dhnkrn)
- Fix -EDEADLK handling in debugfs. (dhnkrn)
- Clean up waiting for idle in intel_psr_set_debugfs_mode.
- Print PSR mode when trying to enable PSR. (dhnkrn)
- Move changing psr debug setting to i915_edp_psr_debug_set. (dhnkrn)
Changes since v4:
- Return error in _set() function.
- Change flag values to make them easier to remember. (dhnkrn)
- Only assign psr.dp once. (dhnkrn)
- Only set crtc_state->has_psr on the crtc with psr.dp.
- Fix typo. (dhnkrn)
Changes since v5:
- Only wait for PSR idle on the PSR connector correctly. (dhnkrn)
- Reinstate WARN_ON(drrs.dp) in intel_psr_enable. (dhnkrn)
- Remove stray comment. (dhnkrn)
- Be silent in intel_psr_compute_config on wrong connector. (dhnkrn)

550f17441f drm/cirrus: flip default from 24bpp to 16bpp
The problem with 24bpp is that it is a rather unusual depth these days,
cirrus is pretty much the only relevant device still using that, and it
is a endless source of issues.  Wayland doesn't support it at all.  Bugs
in Xorg keep showing up.

Typically either 32bpp or 16bpp are used.  Using 32bpp would limit the
resolution to 800x600 due to hardware constrains.  So lets go with 16bpp.

Also use the default depth for the framebuffer console and
mode_info->preferred_depth.

abf7b30d7f drm/cirrus: Use drm_framebuffer_put to avoid kernel oops in clean-up
In the Cirrus driver, the regular clean-up code also performs the clean-up
of a failed initialization. If the fbdev's framebuffer was not initialized,
the clean-up will fail within drm_framebuffer_unregister_private. Booting
with cirrus.bpp=16 triggers this bug.

The framebuffer is currently stored directly within struct cirrus_fbdev. To
fix the bug, we turn it into a pointer that is only set for initialized
framebuffers. The fbdev's clean-up code skips uninitialized framebuffers.

The memory for struct drm_framebuffer is allocated dynamically. This requires
additional error handling within cirrusfb_create. The framebuffer clean-up is
now performed by drm_framebuffer_put, which also frees the data strcuture's
memory.

Extend the timeout for recovering vram bos from shadows on sr-iov

Under runtime, the wait fence time could be quite long when
other VFs are in exclusive mode. For example, for 4 VF, every
VF's exclusive timeout time is set to 3s, then the worst case is
9s. If the VF number is more than 4,then the worst case time will
be longer.
The 8s is the test data, with setting to 8s, it will pass the TDR

d9fcdc8d1f drm/i915: Use existing power well IDs where possible
There is no need for separate IDs for power wells on a new platform with
the same functionality as an other power well on a previous platform, we
can just reuse the ID from the previous platform. This is only possible
after the previous patches where we removed dependence on the actual
enum values.

This also fixes a problem on ICL where in assert_can_enable_dc5/9() we
would've failed to look up the PW#2 power well.

v2:
- Keep an ID assigned for the ICL PW#2 power well too. (Paulo)

4739a9d243 drm/i915: Remove redundant power well IDs
Now that we removed dependence on the power well IDs to determine the
control register and request/status flag offsets the only purpose of
power well IDs is to look up power wells directly bypassing the power
domains framework. However this direct lookup isn't needed for most of
the exisiting power wells and hopefully won't be needed for any new
power wells in the future. To make maintenance of the power well ID enum
easier, don't require a unique ID for each power well, only if it's
necessary. Remove the IDs becoming redundant this way and assign to all
the corresponding power wells a new DISP_PW_ID_NONE ID.

After the previous two patches the IDs don't need to have a fixed value,
so remove the explicit initializers and adjust the enum's code comment
accordingly.

v2:
- Keep required ID assignments for HSW_DISP_PW_GLOBAL and ICL_DISP_PW_2.

75e39688f3 drm/i915/ddi: Use power well CTL IDX instead of ID
Similarly to the previous patch use a separate request/status HW flag
index defined right after the corresponding control registers instead of
depending for this on the power well IDs. Since the set of
control/status registers varies among the different power wells (on a
single platform), also add a new i915_power_well_registers struct that
we populate and assign to each DDI power well as needed.

Also clarify a bit the code comment describing the function and layout
of the control registers.

This also fixes a problem on ICL, where we incorrectly read the KVMR
control register in hsw_power_well_requesters() even for DDI and AUX
power wells.

v2:
- Clarify platform range tags in code comments. (Paulo)
- Fix line over 80 chars checkpatch warning.

d13dd05a1f drm/i915/vlv: Use power well CTL IDX instead of ID
Atm, we determine the control/status flag offsets within the PUNIT
control/status registers based on the power well's ID. Since the power
well ID enum is global across all platforms, the associated macros to
get the flag offsets involves some magic. This makes checking the
register/bit definitions against the specification more difficult than
necessary. Also the values in the power well ID enum must stay fixed,
making code maintenance of the enum cumbersome.

To solve the above define the control/status flag indices right after
the corresponding registers and use these to derive the control/status
flag values by storing the indices in the i915_power_well_desc struct.

Initializing anonymous union fields require the preceding field in the
struct to be explicitly initialized - even when using named
initializers - and the initialization to be done right before the union
initialization, hence the reordering of the .id fields.

v2:
- Clarify commit log message about anonymous union initializers. (Paulo)

cf1f697acb drm/i915/skl: distribute DDB based on panel resolution
We distribute DDB equally among all pipes irrespective of display
buffer requirement of each pipe. This leads to a situation where high
resolution y-tiled display can not be enabled with 2 low resolution
displays.

Main contributing factor for DDB requirement is width of the display.
This patch make changes to distribute ddb based on display width.
So display with higher width will get bigger chunk of DDB.

Changes Since V1:
 - pipe_size/ddb_size will not overflow u16 so use appropriate
   data-types during computation (Chris)
Changes Since V2:
 - avoid redundancy and possible truncation errors (Chris)

4823e5da2e drm/scheduler: fix timeout worker setup for out of order job completions
drm_sched_job_finish() is a work item scheduled for each finished job on
a unbound system workqueue. This means the workers can execute out of order
with regard to the real hardware job completions.

If this happens queueing a timeout worker for the first job on the ring
mirror list is wrong, as this may be a job which has already finished
executing. Fix this by reorganizing the code to always queue the worker
for the next job on the list, if this job hasn't finished yet. This is
robust against a potential reordering of the finish workers.

Also move out the timeout worker cancelling, so that we don't need to
take the job list lock twice. As a small optimization list_del is used
to remove the job from the ring mirror list, as there is no need to
reinit the list head in the job we are about to free.

5ae6fe5729 drm/amd/display: Use calculated disp_clk_khz value for dce110
[Why]

The calculated values for actual disp_clk_khz were ignored when
notifying pplib of the new display requirements. In order to honor DFS
bypass clocks from the hardware, the calculated value should be used.

[How]

The return value for set_dispclk is now assigned back into new_clocks
and correctly carried through into dccg->clks.phyclk_khz. When notifying
pplib of new display requirements dccg->clks.phyclk_khz is used
instead of dce.dispclk_khz. The value of dce.dispclk_khz was never
explicitly set to anything before.

A 15% higher display clock value than calculated is no longer requested
for dce110 since it now makes use of the calculated value.

Since dce112 makes use of dce110's set_bandwidth but not its
update_clocks it needs to have the value correctly carried through.

027063b160 drm/i915: Interactive RPS mode
RPS provides a feedback loop where we use the load during the previous
evaluation interval to decide whether to up or down clock the GPU
frequency. Our responsiveness is split into 3 regimes, a high and low
plateau with the intent to keep the gpu clocked high to cover occasional
stalls under high load, and low despite occasional glitches under steady
low load, and inbetween. However, we run into situations like kodi where
we want to stay at low power (video decoding is done efficiently
inside the fixed function HW and doesn't need high clocks even for high
bitrate streams), but just occasionally the pipeline is more complex
than a video decode and we need a smidgen of extra GPU power to present
on time. In the high power regime, we sample at sub frame intervals with
a bias to upclocking, and conversely at low power we sample over a few
frames worth to provide what we consider to be the right levels of
responsiveness respectively. At low power, we more or less expect to be
kicked out to high power at the start of a busy sequence by waitboosting.

Prior to commit e9af4ea2b9 ("drm/i915: Avoid waitboosting on the active
request") whenever we missed the frame or stalled, we would immediate go
full throttle and upclock the GPU to max. But in commit e9af4ea2b9, we
relaxed the waitboosting to only apply if the pipeline was deep to avoid
over-committing resources for a near miss. Sadly though, a near miss is
still a miss, and perceptible as jitter in the frame delivery.

To try and prevent the near miss before having to resort to boosting
after the fact, we use the pageflip queue as an indication that we are
in an "interactive" regime and so should sample the load more frequently
to provide power before the frame misses it vblank. This will make us
more favorable to providing a small power increase (one or two bins) as
required rather than going all the way to maximum and then having to
work back down again. (We still keep the waitboosting mechanism around
just in case a dramatic change in system load requires urgent uplocking,
faster than we can provide in a few evaluation intervals.)

v2: Reduce rps_set_interactive to a boolean parameter to avoid the
confusion of what if they wanted a new power mode after pinning to a
different mode (which to choose?)
v3: Only reprogram RPS while the GT is awake, it will be set when we
wake the GT, and while off warns about being used outside of rpm.
v4: Fix deferred application of interactive mode
v5: s/state/interactive/
v6: Group the mutex with its principle in a substruct

08e3e21a24 drm/i915: kill resource streamer support
After disabling resource streamer on ICL (due to it actually not
existing there), I got feedback that there have been some experimental
patches for mesa to use RS years ago, but nothing ever landed or shipped
because there was no performance improvement.

This removes it from kernel keeping the uapi defines around for
compatibility.

v2: - re-add the inadvertent removal of CTX_CTRL_INHIBIT_SYN_CTX_SWITCH
    - don't bother trying to document removed params on uapi header:
      applications should know that from the query.
      (from Chris)

v3: - disable CTX_CTRL_RS_CTX_ENABLE istead of removing it
    - reword commit message after Daniele confirmed no performance
      regression on his machine
    - reword commit message to make clear RS is being removed due to
      never been used
v4: - move I915_EXEC_RESOURCE_STREAMER to __I915_EXEC_ILLEGAL_FLAGS so
      the check on ioctl() is made much earlier by
      i915_gem_check_execbuffer() (suggested by Tvrtko)

5b14746553 drm/etnaviv: fix crash in GPU suspend when init failed due to buffer placement
When the suballocator was unable to provide a suitable buffer for the MMUv1
linear window, we roll back the GPU initialization. As the GPU is runtime
resumed at that point we need to clear the kernel cmdbuf suballoc entry to
properly skip any attempt to manipulate the cmdbuf when the GPU gets shut
down in the runtime suspend later on.

447ae31667 x86: Don't include linux/irq.h from asm/hardirq.h
The next patch in this series will have to make the definition of
irq_cpustat_t available to entering_irq().

Inclusion of asm/hardirq.h into asm/apic.h would cause circular header
dependencies like

  asm/smp.h
    asm/apic.h
      asm/hardirq.h
        linux/irq.h
          linux/topology.h
            linux/smp.h
              asm/smp.h

or

  linux/gfp.h
    linux/mmzone.h
      asm/mmzone.h
        asm/mmzone_64.h
          asm/smp.h
            asm/apic.h
              asm/hardirq.h
                linux/irq.h
                  linux/irqdesc.h
                    linux/kobject.h
                      linux/sysfs.h
                        linux/kernfs.h
                          linux/idr.h
                            linux/gfp.h

and others.

This causes compilation errors because of the header guards becoming
effective in the second inclusion: symbols/macros that had been defined
before wouldn't be available to intermediate headers in the #include chain
anymore.

A possible workaround would be to move the definition of irq_cpustat_t
into its own header and include that from both, asm/hardirq.h and
asm/apic.h.

However, this wouldn't solve the real problem, namely asm/harirq.h
unnecessarily pulling in all the linux/irq.h cruft: nothing in
asm/hardirq.h itself requires it. Also, note that there are some other
archs, like e.g. arm64, which don't have that #include in their
asm/hardirq.h.

Remove the linux/irq.h #include from x86' asm/hardirq.h.

Fix resulting compilation errors by adding appropriate #includes to *.c
files as needed.

Note that some of these *.c files could be cleaned up a bit wrt. to their
set of #includes, but that should better be done from separate patches, if
at all.

6c234fe37c drm/vkms: Implement CRC debugfs API
This patch implement the necessary functions to compute and add CRCs
entries:

- Implement the set_crc_source() callback.
- Compute CRC using crc32 on the visible part of the framebuffer.
- Use ordered workqueue per output to compute and add CRC at the end
  of a vblank.
- Use appropriate synchronization methods since the CRC computation must
  be atomic wrt the generated vblank event for a given atomic update, by
  using spinlock across atomic_begin/atomic_flush to wrap the event
  handling code completely and match the flip event with the CRC.

Since vkms_crc_work_handle() can sleep, spinlock can't be acquired
while accessing vkms_output->primary_crc to compute CRC.
To make sure the data is updated and released without conflict with
the vkms_crc_work_handle(), the work_struct is flushed @crtc_destroy
and the data is updated before scheduling the work handle again, as
follow:

* CRC data update:
1- store vkms_crc_data {fb, src} per plane_state
2- @plane_duplicate_state -> allocate vkms_crc_data
3- during atomic commit (@atomic_update) ->
	a) copy {fb, src} to plane_state->crc_data
	b) get reference to fb,
3- @plane_destroy_state -> a) if (fb refcount) remove reference to fb
			   b) deallocate crc_data

* Atomic Commit:
1- vkms_plane_atomic_check
2- vkms_prepare_fb -> vmap vkms_gem_obj->vaddr
3- atomic_begin -> hold crc spinlock
4- atomic_plane_update -> a) update vkms_output->primary_crc
			  b) get reference to fb
5- atomic_flush -> a) send vblank event while holding event_lock
		   b) release crc spinlock

* hrtimer regular callback:
1- hold crc spinlock
2- drm_crtc_handle_vblank()
3- queue vkms_crc_work_handle
4- release crc spinlock

* cleanup:
1- @cleanup_fb ->vunmap vkms_gem_obj->vaddr
2- @crtc_destroy -> flush work struct
3- @plane_destroy -> a) if (fb refcount) remove reference to fb
		     b) deallocate crc_data

If connector_signal is not DP abort detection if we can't retrieve the

c358514ba8 Revert "drm/i915/icl: WaEnableFloatBlendOptimization"
The register for 0xe420 is unable to hold any value, including
this bit. The documentation is also mixed between having a
register bit for toggle and having a state command setup
for it. Apparently the register toggle is deprecated.

Remove the register toggle as evidence shows it's futile.

The thing remaining is an apology and humble request for
Mesa folks to resurrect their state setup for this as they
were on right track from start.

This reverts commit 0bf059f353.

This set of changes migrates Armada DRM from legacy modeset to atomic
modeset.  This is everything from the "Transition Armada DRM planes to
atomic state" and "Finish Armada DRM transition to atomic modeset"
patch sets as posted on drm-devel, excluding the "Finish Armada DRM DT
support" series.

These series did not evoke any comments - if there are any, these can
be addressed via follow up patches.

Developed and tested on Dove Cubox with xf86-video-armada including the
overlay plane, and also tested with the tools in libdrm.

A bit larger this time around, due to introduction of "dpu1" support
for the display controller in sdm845 and beyond.  This has been on
list and undergoing refactoring since Feb (going from ~110kloc to
~30kloc), and all my review complaints have been addressed, so I'd be
happy to see this upstream so further feature work can procede on top
of upstream.

Also includes the gpu coredump support, which should be useful for
debugging gpu crashes.  And various other misc fixes and such.

ddf74e79a5 drm/amdgpu/pm: Fix potential Spectre v1
idx can be indirectly controlled by user-space, hence leading to a
potential exploitation of the Spectre variant 1 vulnerability.

This issue was detected with the help of Smatch:

drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c:408 amdgpu_set_pp_force_state()
warn: potential spectre issue 'data.states'

Fix this by sanitizing idx before using it to index data.states

Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

77605e4370 drm/radeon: Replace ttm_bo_unref with ttm_bo_put
The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.

A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.

The current behaviour of cleaning the pointer is kept in the calling code,
but should be removed if not required in a later patch.

60548c554b drm/i915: Interactive RPS mode
RPS provides a feedback loop where we use the load during the previous
evaluation interval to decide whether to up or down clock the GPU
frequency. Our responsiveness is split into 3 regimes, a high and low
plateau with the intent to keep the gpu clocked high to cover occasional
stalls under high load, and low despite occasional glitches under steady
low load, and inbetween. However, we run into situations like kodi where
we want to stay at low power (video decoding is done efficiently
inside the fixed function HW and doesn't need high clocks even for high
bitrate streams), but just occasionally the pipeline is more complex
than a video decode and we need a smidgen of extra GPU power to present
on time. In the high power regime, we sample at sub frame intervals with
a bias to upclocking, and conversely at low power we sample over a few
frames worth to provide what we consider to be the right levels of
responsiveness respectively. At low power, we more or less expect to be
kicked out to high power at the start of a busy sequence by waitboosting.

Prior to commit e9af4ea2b9 ("drm/i915: Avoid waitboosting on the active
request") whenever we missed the frame or stalled, we would immediate go
full throttle and upclock the GPU to max. But in commit e9af4ea2b9, we
relaxed the waitboosting to only apply if the pipeline was deep to avoid
over-committing resources for a near miss. Sadly though, a near miss is
still a miss, and perceptible as jitter in the frame delivery.

To try and prevent the near miss before having to resort to boosting
after the fact, we use the pageflip queue as an indication that we are
in an "interactive" regime and so should sample the load more frequently
to provide power before the frame misses it vblank. This will make us
more favorable to providing a small power increase (one or two bins) as
required rather than going all the way to maximum and then having to
work back down again. (We still keep the waitboosting mechanism around
just in case a dramatic change in system load requires urgent uplocking,
faster than we can provide in a few evaluation intervals.)

v2: Reduce rps_set_interactive to a boolean parameter to avoid the
confusion of what if they wanted a new power mode after pinning to a
different mode (which to choose?)
v3: Only reprogram RPS while the GT is awake, it will be set when we
wake the GT, and while off warns about being used outside of rpm.
v4: Fix deferred application of interactive mode
v5: s/state/interactive/
v6: Group the mutex with its principle in a substruct

and dump them for the crash state.

Also, remove a block of registers the regular CPU accessible
list that aren't useful for debug which helps reduce the size
of the crash state file by a goodly amount.

c50dfe79ec drm/i915/icl: don't set CNL_DDI_CLOCK_REG_ACCESS_ON anymore
The new recommendation from the spec is to simply not set this bit
anymore. Not setting the bit would prevent some hangs that our driver
manages to avoid since commit c8af5274c3 ("drm/i915: enable the
pipe/transcoder/planes later on HSW+"), and the theoretical downside
of not setting the bit doesn't seem realistic according to the HW
team. Let's follow their recommendation.

496bcce3c9 drm/i915: Remove unnecessary ggtt_offset_bias from i915_gem_context
Since ggtt_offset_bias is now stored in ggtt.pin_bias, it is duplicated
inside i915_gem_context, and can instead be accessed directly from ggtt.

v3:
Added a helper function to retrieve the ggtt.pin_bias from the vma.

v4:
Moved the helper function to the previous patch in the series.
Dropped the bias from intel_ring_pin. This introduces a slight functional
change since we are always pinning the ring a bit higher if GuC is present
even though we don't really need to.

v8:
Fixed patch not applying on the most recent upstream.

dd18cedfa3 drm/i915/guc: Move the pin bias value from GuC to GGTT
Removing the pin bias from GuC allows us to not check for GuC every time
we pin a context, which fixes the assertion error on unresolved GuC
platform default in mock contexts selftest.

It also seems that we were using uninitialized WOPCM variables when
setting the GuC pin bias. The pin bias has to be set after the WOPCM,
but before the call to i915_gem_contexts_init where the first contexts
are pinned.

v2:
This also makes it so that there's no need to set GuC variables from
within the WOPCM init function or to move the WOPCM init, while keeping
the correct initialization order. Also for mock tests the pin bias is
left at 0 and we make sure that the pin bias with GuC will not be
smaller than without GuC.

v3:
Avoid unused i915 in intel_guc_ggtt_offset if debug is disabled.

v4:
Squash with WOPCM init reordering.
Moved the i915_ggtt_pin_bias helper to this patch, and made some
functions use it instead of directly dereferencing i915->ggtt.

v5:
Since we now don't use wopcm.guc.base for the pin bias there's no need to
validate it. It also has already been verified in WOPCM init.

v6:
Deleted the now unnecessarily introduced includes from previous versions.
Dropped naming changes from dev_priv to i915 for better patch readability.

v7:
Changed some comments to make more sense in the context they're in.

v8:
Moved and renamed the function which now returns the wopcm.guc.size to
intel_guc.c:intel_guc_reserved_gtt_size to avoid any possible confusion
with the pin_bias in ggtt, which should be used for pinning.
Fixed patch not applying or the most recent upstream.

It would appear that the calculated GuC pin bias was larger than it should

of the WOPCM. Thus, the GuC pin bias is simply the GuC WOPCM size.

v5:

validate it. It also has already been verified in WOPCM init.

a095f15c00 drm/bridge: add support for sn65dsi86 bridge driver
Add support for TI's sn65dsi86 dsi2edp bridge chip.
The chip converts DSI transmitted signal to eDP signal,
which is fed to the connected eDP panel.

This chip can be controlled via either i2c interface or
dsi interface. Currently in driver all the control registers
are being accessed through i2c interface only.
Also as of now HPD support has not been added to bridge
chip driver.

Changes in v1:
 - Split the dt-bindings and the driver support into separate patches
   (Andrzej Hajda).
 - Use of gpiod APIs to parse and configure gpios instead of obsolete ones
   (Andrzej Hajda).
 - Use macros to define the register offsets (Andrzej Hajda).

Changes in v2:
 - Separate out edp panel specific HW resource handling from bridge
   driver and create a separate edp panel drivers to handle panel
   specific mode information and HW resources (Sean Paul).
 - Replace pr_* APIs to DRM_* APIs to log error or debug information
   (Sean Paul).
 - Remove some of the unnecessary structure/variable from driver (Sean
   Paul).
 - Rename the function and structure prefix "sn65dsi86" to "ti_sn_bridge"
   (Sean Paul / Rob Herring).
 - Remove most of the hard-coding and modified the bridge init sequence
   based on current mode (Sean Paul).
 - Remove the existing function to retrieve the EDID data and
   implemented this as an i2c_adapter and use drm_get_edid() (Sean Paul).
 - Remove the dummy irq handler implementation, will add back the
   proper irq handling later (Sean Paul).
 - Capture the required enable gpios in a single array based on dt entry
   instead of having individual descriptor for each gpio (Sean Paul).

Changes in v3:
 - Remove usage of irq_gpio and replace it as "interrupts" property (Rob
   Herring).
 - Remove the unnecessary header file inclusions (Sean Paul).
 - Rearrange the header files in alphabetical order (Sean Paul).
 - Use regmap interface to perform i2c transactions.
 - Update Copyright/License field and address other review comments
   (Jordan Crouse).

Changes in v4:
 - Update License/Copyright (Sean Paul).
 - Add Kconfig and Makefile changes (Sean Paul).
 - Drop i2c gpio handling from this bridge driver, since i2c sda/scl gpios
   will be handled by i2c master.
 - Update required supplies names.
 - Remove unnecessary goto statements (Sean Paul).
 - Add mutex lock to power_ctrl API to avoid race conditions (Sean
   Paul).
 - Add support to parse reference clk frequency from dt(optional).
 - Update the bridge chip enable/disable sequence.

Changes in v5:
 - Fixed Kbuild test service reported warnings.

Changes in v6:
 - Use PM runtime based ref-counting instead of local ref_count mechanism
   (Stephen Boyd).
 - Clean up some debug logs and indentations (Sean Paul).
 - Simplify dp rate calculation (Sean Paul).
 - Add support to configure refclk based on input REFCLK pin or DACP/N
   pin (Stephen Boyd).

Changes in v7:
 - Use static supply entries instead of dynamic allocation (Andrzej
   Hajda).
 - Defer bridge driver probe if panel is not probed (Andrzej Hajda).
 - Update of_graph APIs for correct node reference management. (Andrzej
   Hajda).
 - Remove local display_mode object (Andrzej Hajda).
 - Remove version id check function from driver.

Changes in v8:
 - Move dsi register/attach function to bridge driver probe (Andrzej
   Hajda).
 - Introduce a new helper function to write 16bit words into consecutive
   registers (Andrzej Hajda).
 - Remove unnecessary macros (Andrzej Hajda).

Changes in v9:
 - Remove dsi register/attach from bridge probe, since dsi dev register
   completion also waits for any panel or bridge to get added. This creates
   deadlock situation when bridge driver calls dsi dev register and
   attach before bridge add, in its probe function.
 - Fix issues faced during testing of bridge driver on actual HW.
 - Remove unnecessary initializations (Stephen Boyd).
 - Use local refclk lut size instead of global macro (Sean Paul).

Changes in v10:
 - Use refclk to determine if continuous dsi clock is needed or not.

Changes in v11:
 - Read DPPLL_SRC register to determine continuous clock instead of
   using refclk handle (Stephen Boyd).

Changes in v12:
 - Explain in comment as in why dsi dev registration is done in
   bridge_attach (Andrzej Hajda).
 - Move HPD disable to bridge_pre_enable (Andrzej Hajda).
 - Make panel/DDC exclusive until HPD support is added (Andrzej Hajda).

Changes in v13:
 - eDP panels report EDID via DP-AUX channel, so remove support for
   dedicated DDC line (Andrzej Hajda).

Changes in v14:
 - Remove unnecessary drm_panel checks (Andrzej Hajda).

25fdd5933e drm/msm: Add SDM845 DPU support
SDM845 SoC includes the Mobile Display Sub System (MDSS) which is a
top level wrapper consisting of Display Processing Unit (DPU) and
display peripheral modules such as Display Serial Interface (DSI)
and DisplayPort (DP).

MDSS functions essentially as a back-end composition engine. It blends
video and graphic images stored in the frame buffers and scans out the
composed image to a display sink (over DSI/DP).

The following diagram represents hardware blocks for a simple pipeline
(two planes are present on a given crtc which is connected to a DSI
connector):

       MDSS

      | +----------------------------+  |
      +---------------------------------+

The number of DPU sub-blocks (i.e. SSPPs, LMs, PP blocks and INTFs)
depends on SoC capabilities.

Overview of DPU sub-blocks:
---------------------------
* Source Surface Processor (SSPP):
 Refers to any of hardware pipes like ViG, DMA etc. Only ViG pipes are
 capable of performing format conversion, scaling and quality improvement
 for source surfaces.

* Layer Mixer (LM):
 Blend source surfaces together (in requested zorder)

* PingPong (PP):
 This block controls frame done interrupt output, EOL and EOF generation,
 overflow/underflow control.

* Display interface (INTF):
 Timing generator and interface connecting the display peripherals.

DRM components mapping to DPU architecture:
------------------------------------------
PLANEs maps to SSPPs
CRTC maps to LMs
Encoder maps to PPs, INTFs

Data flow setup:
---------------
MDSS hardware can support various data flows (e.g.):
  - Dual pipe: Output from two LMs combined to single display.
  - Split display: Output from two LMs connected to two separate
                   interfaces.

The hardware capabilities determine the number of concurrent data paths
possible. Any control path (i.e. pipeline w/i DPU) can be routed to any
of the hardware data paths. A given control path can be triggered,
flushed and controlled independently.

Changes in v3:
- Move msm_media_info.h from uapi to dpu/ subdir
- Remove preclose callback dpu (it's handled in core)
- Fix kbuild warnings with parent_ops
- Remove unused functions from dpu_core_irq
- Rename mdss_phys to mdss
- Rename mdp_phys address space to mdp
- Drop _phys from vbif and regdma binding names

controllers to register one connector/bridge.

6dc17d69f8 drm/i915/selftests: Exercise resetting in the middle of a wait-on-fence
On older HW, gen2/3, fence registers are used for detiling GPU commands
and as such changing those registers requires serialisation with the
requests on the GPU. Anything running on the GPU is subject to a hang,
and so we must be able to recover cleanly in the middle of a stuck wait
on a fence register.

We can simulate using the fence on the GPU simply by marking the fence
as active on the request for this vma, the interface being common to all
gen, thus broadening the test.

ab84a11049 drm/i915/selftests: Use a full emulation of a user ppgtt context
To test eviction from a ppgtt, we just want a ppgtt i.e. something other
than the Global GTT which is shared and used by the kernel for HW
features like fencing and scanout. However, we also need it to pass
!i915_is_ggtt() and the simplest way is to emulate a full user context
rather than the internal kernel context that is used for the GGTT.

If we issue a device level GPU reset on the older gen, it will disable

The short pulse handler checks if channel equalization is okay and
goes onto retrain a link if there are active MST links. This retraining
path is not meant for new MST connections, but due to a bug elsewhere, if
active_mst_links is < 0 the boolean check for active_mst_links passes and
we proceed to retrain a new link. This results in a sequence of failed link
training attempts, most likely due to the hardware not setup for link
training at that point i.e., missing the DDI pre_enable sequence.

The above error gives us a hint something went wrong before link
training started.

invalid active_mst_links as debug aid.

0ca9488193 drm/i915/glk: Add Quirk for GLK NUC HDMI port issues.
On GLK NUC platforms the HDMI retiming buffer needs additional disabled
time to correctly sync to a faster incoming signal.

When measured on a scope the highspeed lines of the HDMI clock turn off
 for ~400uS during a normal resolution change. The HDMI retimer on the
 GLK NUC appears to require at least a full frame of quiet time before a
new faster clock can be correctly sync'd. Wait 100ms due to msleep
inaccuracies while waiting for a completed frame. Add a quirk to the
driver for GLK boards that use ITE66317 HDMI retimers.

V2: Add more devices to the quirk list

flushing and sending the START signal before encoder state was updated.
But it did this a little too well in some cases that don't trigger
encoder->enable(), and CTL[n].FLUSH would never be set.  When page flips
happen it would paper over the bug, since the first plag flip would
flush out the state to the hardware.

The issue could be reproduced with, for example, modetest (without the
'-v' argument).

07685c827b drm/i915/icl: Implement voltage swing programming sequence for MG PHY DDI
This sequence is used to setup voltage swing before enabling MG PHY DDI
as well as for changing the voltage during DisplayPort Link training.

For ICL, there are two types of DDIs. This sequence needs to be used
for MG PHY DDI which is ports C-F.

v6 (From Manasi):
* Add programming for MG_CLKHUB and MG_TX_DCC as per the
spec updates

v5 (from Paulo):
* Checkpatch.
v4 (from Paulo):
* Fix bogus error message
* Fix copy+paste bugs (missing s/TX1/TX2/ after copy+paste)
* Use the new mask names
* Stay under 80 columns
* Add some blank lines
v3:
* Clear the regs before writing (Paulo)
v2:
* Rename to MG PHY in the function def (Jani Nikula)
* Rebase on top of new revision of other patches in series

While at it this patch also fixes the naming for previously defined
MG PHY registers in original commit id (c92f47b5ec "drm/i915/icl:
Add register defs for voltage swing sequences for MG PHY DDI").
Since the MG PHY registers are first defined in ICL platform, there
is no need for _ICL prefix.

v4 (from Paulo): add two white spaces to CRI_CALCINIT too.

v3:
* Fix register names, add spaces for MASK defines, correct the order
of #defines (Paulo)

v2:
* Change the MG_TX_DRVCTL registers names to match the spec (Anusha)

Till now, new way of matching engines with TCONs was reading their
respective ids and match them by those ids. However, with introduction
of TCON TOP, that might not be so straightforward anymore.
- there might be more TCONs that engines (mixers)
- TCON ids might have non-consecutive ids

Workaround that by matching mixer id with TCON index from TCON list.

For example, R40 has 2 mixers and 4 TCONs. Board designer can choose
2 outputs, which are connected to any of those 4 TCONs. As long as there
are only 2 TCONs enabled in DT, using index in list as alternative id,
will allow to match them with mixer 0 and 1.

We do not need sun4i_backend_format_is_packed_yuv422() /
sun4i_backend_format_is_planar_yuv() to determine if the format is yuv multi planar
or not. (struct drm_format_info *)->is_yuv tells if the format is yuv or not.
And (struct drm_format_info *)->num_planes denotes the number of planes.

This issue was identified during a review on a previous patch:-

a5b22b5ed8 drm/i915: Show stack (by WARN) for hitting forcewake errors
On Sandybridge, we need a workaround to wait for the CPU thread to wake
up before we are sure that we have enabled the GT power well. However,
we do see the errors being reported and failed reads returning spurious
results. To try and capture more details as it fails, promote the error
into a WARN so we grab the stacktrace, and to try and reduce the
frequency of error increase the timeout from 500us to 5ms.

6a2f59e45a drm/i915: Pull unpin map into vma release
A reasonably common operation is to pin the map of the vma alongside the
vma itself for the lifetime of the vma, and so release both pins at the
same time as destroying the vma. It is common enough to pull into the
release function, making that central function more attractive to a
couple of other callsites.

The continual ulterior motive is to sweep over errors on module load
aborting...

7e915746de drm/exynos: Ensure suspended runtime PM state during system suspend
Add calls to pm_runtime_force_{suspend,resume} as SYSTEM_SLEEP_PM_OPS for
all drivers for the real Exynos DRM hardware modules. This ensures that
the resources will be released for the system PM suspend/resume cycle.
Exynos DRM core already takes care of suspending the whole display pipeline
before PM callbacks of the real devices are called.

dc684af6fc drm/exynos: Suspend/resume display pipeline as early/late as possible
In the current code, exynos_drm_suspend() function is called after all
real devices (CRTCs, Encoders, etc) are suspended, because Exynos DRM
virtual platform device is created as last device in the system (as
a part of DRM registration). None of the devices for real hardware
modules has its own system suspend/resume callbacks, so it doesn't
change any order of the executed code, but it has a side-effect:
runtime PM callbacks for real devices are not executed, because those
devices are considered by PM core as already suspended. This might
cause issues on boards with complex pipelines, where something
depends on the runtime PM state of the given device.

To ensure that exynos_drm_suspend() is called before any suspend
callback from the real devices, assign it to .prepare callback. Same
for exynos_drm_resume(), using .complete callback ensures that all
real devices have been resumed when calling it.

bb5ffe6fd5 drm/i915/dp: Limit link training clock recovery loop
Limit the link training clock recovery loop to 10 attempts at
LANEx_CR_DONE per DP 1.4 spec section 3.5.1.2.2 and 80 attempts for
pre-DP 1.4 (4 voltage levels x 4 preemphasis levels x
x 5 identical voltages tries). Some faulty USB-C MST hubs can
cause us to get stuck in this loop indefinitely requesting something
like:

    voltage swing: 0, pre-emphasis level: 2
    voltage swing: 1, pre-emphasis level: 2
    voltage swing: 0, pre-emphasis level: 3

over and over so max_vswing would never be reached,
drm_dp_clock_recovery_ok() would never return true and voltage_tries
would always get reset to 1. The driver sends those values to the hub
but the hub keeps requesting new values every time.

Changes in v2:
    - updated commit message (DK, Manasi)
    - defined DP_DP14_MAX_CR_TRIES (Marc)
    - made the loop iterate for max 10 times (Rodrigo, Marc)

Changes in v3:

Changes in v4:
    - Updated the title to reflect the change
    - Updated the commit message
    - Added 80 attempts for pre-DP 1.4 devices

The concern here is about consoles other than fbcon on the device,
e.g. a serial console

[How]
This patch restructures the console_lock, console_unlock around
amdgpu_fbdev_set_suspend() and moves this new block appropriately.

V2: Kept amdgpu_fbdev_set_suspend after pci_set_power_state
V3: Updated the commit message to clarify the real concern that this patch
    addresses.
V4: code clean-up.
V5: fixed return value

1bc460a45b drm/amd/display: Honor pplib stutter mask for all ASICs in DC
[Why]
We were only setting this mask for DCN, but should really use it
universally for all ASICs.

[How]
Move the assignment out of the Raven switch statement for all ASICs
other than Stoney and Carrizo.

v2: Keep stutter always on for Carrizo and Stoney (Alex)

900ccf30f9 drm/i915: Only force GGTT coherency w/a on required chipsets
Not all chipsets have an internal buffer delaying the visibility of
writes via the GGTT being visible by other physical paths, but we use a
very heavy workaround for all. We only need to apply that workarounds to
the chipsets we know suffer from the delay and the resulting coherency
issue.

Similarly, the same inconsistent coherency fouls up our ABI promise that
a write into a mmap_gtt is immediately visible to others. Since the HW
has made that a lie, let userspace know when that contract is broken.
(Not that userspace would want to use mmap_gtt on those chipsets for
other performance reasons...)

The warning is seen when mode_setcrtc() is called for pipeB
during bootup and before we get a mode_setcrtc() for pipeA,
while doing update_crtcs() in intel_atomic_commit_tail().
Now since, plane1A is still active after commit, update_crtcs()
is done for pipeA and eventually update_plane() for plane1A.

intel_plane_state->ctl for plane1A is not updated since set_modecrtc() is
called for pipeB. So intel_plane_state->ctl for plane 1A will be 0x0.
So doing an update_plane() for plane1A, will result in clearing
PLANE_CTL_ENABLE bit, and hence the warning.

To fix this warning, force all active planes to recompute their states
in probe.

79556df293 drm/i915/gtt: Enable full-ppgtt by default everywhere
We should we have all the kinks worked out and full-ppgtt now works
reliably on gen7 (Ivybridge, Valleyview/Baytrail and Haswell). If we can
let userspace have full control over their own ppgtt, it makes softpinning
far more effective, in turn making GPU dispatch far more efficient by
virtue of better mm segregation.  On the other hand, switching over to a
different GTT for every client does incur noticeable overhead, but only
for very lightweight tasks.

05c72e77cc drm/i915: Nuke the LVDS lid notifier
We broke the LVDS notifier resume thing in (presumably) commit
e2c8b8701e ("drm/i915: Use atomic helpers for suspend, v2.") as
we no longer duplicate the current state in the LVDS notifier and
thus we never resume it properly either.

Instead of trying to fix it again let's just kill off the lid
notifier entirely. None of the machines tested thus far have
apparently needed it. Originally the lid notifier was added to
work around cases where the VBIOS was clobbering some of the
hardware state behind the driver's back, mostly on Thinkpads.
We now have a few report of Thinkpads working just fine without
the notifier. So maybe it was misdiagnosed originally, or
something else has changed (ACPI video stuff perhaps?).

If we do end up finding a machine where the VBIOS is still causing
problems I would suggest that we first try setting various bits in
the VBIOS scratch registers. There are several to choose from that
may instruct the VBIOS to steer clear.

With the notifier gone we'll also stop looking at the panel status
in ->detect().

v2: Nuke enum modeset_restore (Rodrigo)

drm/sun4i: sun4i: Introduce a quirk for lowest plane alpha support
Not all sunxi platforms with the first version of the Display Engine
support an alpha component on the plane with the lowest z position
(as in: lowest z-pos), that gets blended with the background color.

In particular, the A13 is known to have this limitation. However, it was
recently discovered that the A20 and A33 are capable of having alpha on
their lowest plane.

Thus, this introduces a specific quirk to indicate such support,
per-platform. Since this was not tested on sun4i and sun6i platforms, a
conservative approach is kept and this feature is not supported.

drm/sun4i: Handle DRM_BUS_FLAG_PIXDATA_*EDGE checking if panel is used.
Handle both positive and negative dclk polarity,
according to bus_flags, taking care of this:

On A20 and similar SoCs, the only way to achieve Positive Edge
(Rising Edge), is setting dclk clock phase to 2/3(240°).
By default TCON works in Negative Edge(Falling Edge), this is why phase
is set to 0 in that case.
Unfortunately there's no way to logically invert dclk through IO_POL
register.
The only acceptable way to work, triple checked with scope,
is using clock phase set to 0° for Negative Edge and set to 240° for
Positive Edge.
On A33 and similar SoCs there would be a 90° phase option, but it divides
also dclk by 2.
This patch is a way to avoid quirks all around TCON and DOTCLOCK drivers
for using A33 90° phase divided by 2 and consequently increase code
complexity.

Check if panel is used. TCON can also handle VGA DAC, then panel could
be empty.

d78d3343dc drm/i915/execlists: Move the assertion we have the rpm wakeref down
There's a race between idling the engine and finishing off the last
tasklet (as we may kick the tasklets after declaring an individual
engine idle). However, since we do not need to access the device until
we try to submit to the ELSP register (processing the CSB just requires
normal CPU access to the HWSP, and when idle we should not need to
submit!) we can defer the assertion unto that point. The assertion is
still useful as it does verify that we do hold the longterm GT wakeref
taken from request allocation until request completion.

override the engine->set_default_submission hook letting execlists sneak
back in temporarily on unwedging leading to an unbalanced park/unpark.

and plan to also call disable before suspend and reset, in which case we
will either restore guc submission or mark the driver as wedged, making
the reset back to execlists pointless.

5fd9df6ac6 drm/i915: Kill sink_crc for good
It was originally introduced following the VESA spec in order to validate PSR.

However we found so many issues around sink_crc that instead of helping PSR
development it only brought another layer of trouble to the table.

So, sink_crc has been a black whole for us in question of time, effort and hope.

First of the problems is that HW statement is clear: "Do not attempt to use
aux communication with PSR enabled". So the main reason behind sink_crc is
already compromised.

For a while we had hope on the aux-mutex could workaround this problem on SKL+
platforms, but that mutex was not reliable, not tested,
and we shouldn't use according to HW engineers.

Also, nor source, nor sink designed and implemented the sink_crc to be used like
we are trying to use here.

Well, the sink side of things is also apparently not prepared for this
case. Each panel that we tried seemed to have a different behavior with same
code and same source.

So, for all the time we lost on trying to ducktape all these different issues
I believe it is now time to move PSR to a more reliable validation.
Maybe not a perfect one as we dreamed for this sink_crc, but at least more
reliable.

As we hold the struct_mutex, always do a quick request retirement in

a57942bfdd ALSA: hda: Make audio component support more generic
This is the final step for more generic support of DRM audio
component.  The generic audio component code is now moved to its own
file, and the symbols are renamed from snd_hac_i915_* to
snd_hdac_acomp_*, respectively.  The generic code is enabled via the
new kconfig, CONFIG_SND_HDA_COMPONENT, while CONFIG_SND_HDA_I915 is
kept as the super-class.

Along with the split, three new callbacks are added to audio_ops:
pin2port is for providing the conversion between the pin number and
the widget id, and master_bind/master_unbin are called at binding /
unbinding the master component, respectively.  All these are optional,
but used in i915 implementation and also other later implementations.

A note about the new snd_hdac_acomp_init() function: there is a slight
difference between this and the old snd_hdac_i915_init().  The latter
(still) synchronizes with the master component binding, i.e. it
assures that the relevant DRM component gets bound when it returns, or
gives a negative error.  Meanwhile the new function doesn't
synchronize but just leaves as is.  It's the responsibility by the
caller's side to synchronize, or the caller may accept the
asynchronous binding on the fly.

ae891abe7c drm/i915: Split audio component to a generic type
For allowing other drivers to use the DRM audio component, rename the
i915_audio_component_* with drm_audio_component_*, and split the
generic part into drm_audio_component.h.  The i915 specific stuff
remains in struct i915_audio_component, which contains
drm_audio_component as the base.

The license of drm_audio_component.h is kept to MIT as same as the the
original i915_component.h.

This is a preliminary change for further development, and no
functional changes by this patch itself, merely code-split and
renames.

a8bd3b884d drm/i915: Flush chipset caches after GGTT writes
Our I915g (early gen3, the oldest machine we have in the farm) is still
reporting occasional incoherency performing the following operations:

  1) write through GGTT (indirect write into memory)
  2) write through either CPU or WC (direct write into memory)
  3) read from GGTT (indirect read)

Instead of reporting the value from (2), the read from GGTT reports the
earlier value written via the GGTT. We have made sure that the writes are
flushed from the CPU (commit 3a32497f0d ("drm/i915/selftests: Provide
full mb() around clflush") and commit add00e6d89 ("drm/i915: Flush the
WCB following a WC write")), but still see the error, just less
frequently. The only remaining cache that might be affected here is a
chipset cache, so flush that as well.

drm/sun4i: sun8i: Avoid clearing blending order at each atomic commit
Blending order is set based on the z position of each DRM plane. The
blending order register is currently cleared at each atomic DRM commit,
with the intent that each committed plane will set the appropriate
bits (based on its z-pos) when enabling the plane.

However, it sometimes happens that a particular plane is left unchanged
by an atomic commit and thus will not be configured again. In that
scenario, blending order is cleared and only the bits relevant for the
planes affected by the commit are set. This leaves the planes that did
not change without their blending order set in the register, leading
to that plane not being displayed.

Instead of clearing the blending order register at every atomic commit,
this change moves the register's initial clear at bind time and only
clears the bits for a specific plane when disabling it or changing its
zpos.

This way, planes that are left untouched by a DRM atomic commit are
no longer disabled.

d778847208 drm/i915/selftests: Free the backing store between iterations
In the huge pages tests, we may have lots of objects being trapped on
the freelist as we hold the struct_mutex allowing the free worker no
opportunity to recover the backing store. We also have stricter
requirements and the desire for large contiguous pages, further
increasing the allocation pressure. To reduce the chance of running out
of memory, we could either drop the mutex and flush the free worker, or
we could release the backing store directly. We do the latter in this
patch for simplicity.

register_process is called when the first queue of a process is

is destroyed. The first process that is registered takes compute
out of idle. The last process that is unregisters sets compute back

a18b219294 drm/dp_helper: Add DP aux channel tracing
This is something we've needed for a very long time now, as it makes
debugging issues with faulty MST hubs along with debugging issues
regarding us interfacing with hubs correctly vastly easier to debug.
Currently this can actually be done if you trace the i2c devices for DP
using ftrace but that's significantly less useful for a couple of
reasons:

- Tracing the i2c devices through ftrace means all of the traces are
  going to contain a lot of "garbage" output that we're sending over the
  i2c line. Most of this garbage comes from retrying transactions, DRM's
  helper library adding extra transactions to work around bad hubs, etc.
- Having a user set up ftrace so that they can provide debugging
  information is a lot more difficult then being able to say "just boot
  with drm.debug=0x100"
- We can potentially expand upon this tracing in the future to print
  debugging information in regards to other DP transactions like MST
  sideband transactions

This is inspired by a patch Rob Clark sent to do this a long time back.
Neither of us could find the patch however, so we both assumed it would
probably just be easier to rewrite it anyway.

active before the imx-drm driver is loaded (like when a bootsplash was

the driver. The LDB control registers are not part of the IPU range and
thus will remain unchanged.

This leads to the LDB still being active when the DI is getting enabled,
effectively reversing the required enable sequence. Fix this by also

If we declare the driver wedged before the GPU truly is, then we may see
the GPU complete some CS events following our cancellation. This leaves
us quite confused as we deleted all the bookkeeping and thus complain
about the inconsistent state.

We can just ignore the remaining events and let the GPU idle by not
feeding it, and so avoid trying to racily overwrite shared state. We
rely on there being a full GPU reset before unwedging, giving us the
opportunity to reset the shared state.

3273fc63e1 drm/meson: Make DMT timings parameters and pixel clock generic
Remove the modes timings tables for DMT modes and calculate the HW
paremeters from the modes timings.

Switch the DMT modes pixel clock calculation out of the static frequency
list to a generic calculation from a range of possible PLL dividers.

This patch is an intermediate step towards usage of the Common Clock
Framwework for PLL setup, by reworking the code to have common
sel_pll() function called by the CEA (HDMI) freq setup and the generic
DMT frequencies setup, we should be able to simply call clk_set_rate()
on the PLL clock handle in a near future.

The CEA (HDMI) and CVBS modes needs very specific clock paths that CCF will
never be able to determine by itself, so there is still some work to do for
a full handoff to CCF handling the clocks.

This setup permits setting non-CEA modes like :
- 1600x900-60Hz
- 1280x1024-75Hz
- 1280x1024-60Hz
- 1440x900-60Hz
- 1366x768-60Hz

b59fb482b5 drm/nouveau: tegra: Detach from ARM DMA/IOMMU mapping
Depending on the kernel configuration, early ARM architecture setup code
may have attached the GPU to a DMA/IOMMU mapping that transparently uses
the IOMMU to back the DMA API. Tegra requires special handling for IOMMU
backed buffers (a special bit in the GPU's MMU page tables indicates the
memory path to take: via the SMMU or directly to the memory controller).
Transparently backing DMA memory with an IOMMU prevents Nouveau from
properly handling such memory accesses and causes memory access faults.

As a side-note: buffers other than those allocated in instance memory
don't need to be physically contiguous from the GPU's perspective since
the GPU can map them into contiguous buffers using its own MMU. Mapping
these buffers through the IOMMU is unnecessary and will even lead to
performance degradation because of the additional translation. One
exception to this are compressible buffers which need large pages. In
order to enable these large pages, multiple small pages will have to be
combined into one large (I/O virtually contiguous) mapping via the
IOMMU. However, that is a topic outside the scope of this fix and isn't
currently supported. An implementation will want to explicitly create
these large pages in the Nouveau driver, so detaching from a DMA/IOMMU
mapping would still be required.

2ae4c5f6ff drm/nouveau/kms/nv50-: Allow vblank_disable_immediate
With instantaneous high precision vblank timestamping
that updates at leading edge of vblank, the emulated
"hw vblank counter" from vblank timestamping, which
increments at leading edge of vblank, and reliable
page flip execution and completion at leading edge of
vblank, we should meet the requirements for fast/
immediate vblank irq disable/enable.

This is only allowed on nv50+ gpu's, ie. the ones with
atomic modesetting. One requirement for immediate vblank
disable is that high precision vblank timestamping works
reliably all the time on all connectors. This is not the
case on all pre-nv50 parts for analog VGA outputs, where we
currently don't always have support for scanout position
queries and therefore fall back to vblank interrupt
timestamping. The implementation in nv04_head_state() does
not return valid values for vblanks, vtotal, hblanks, htotal
for VGA outputs on all cards, but those are needed for scanout
position queries.

Testing on Linux-4.12-rc5 + drm-next on a GeForce 9500 GT
(NV G96) with timing measurement equipment indicates this
works fine, so allow immediate vblank disable for power
saving.

For debugging in case of unexpected trouble, booting
with kernel cmdline option drm.vblankoffdelay=0
(or echo 0 > /sys/module/drm/parameters/vblankoffdelay)
would keep vblank irqs permanently on to approximate old
behavior.

eb493fbc15 drm/nouveau: Set DRIVER_ATOMIC cap earlier to fix debugfs
Currently nouveau doesn't actually expose the state debugfs file that's
usually provided for any modesetting driver that supports atomic, even
if nouveau is loaded with atomic=1. This is due to the fact that the
standard debugfs files that DRM creates for atomic drivers is called
when drm_get_pci_dev() is called from nouveau_drm.c. This happens well
before we've initialized the display core, which is currently
responsible for setting the DRIVER_ATOMIC cap.

So, move the atomic option into nouveau_drm.c and just add the
DRIVER_ATOMIC cap whenever it's enabled on the kernel commandline. This
shouldn't cause any actual issues, as the atomic ioctl will still fail
as expected even if the display core doesn't disable it until later in
the init sequence. This also provides the added benefit of being able to
use the state debugfs file to check the current display state even if
clients aren't allowed to modify it through anything other than the
legacy ioctls.

Additionally, disable the DRIVER_ATOMIC cap in nv04's display core, as
this was already disabled there previously.

37afe55b4a drm/nouveau: Avoid looping through fake MST connectors
When MST and atomic were introduced to nouveau, another structure that
could contain a drm_connector embedded within it was introduced; struct
nv50_mstc. This meant that we no longer would be able to simply loop
through our connector list and assume that nouveau_connector() would
return a proper pointer for each connector, since the assertion that
all connectors coming from nouveau have a full nouveau_connector struct
became invalid.

Unfortunately, none of the actual code that looped through connectors
ever got updated, which means that we've been causing invalid memory
accesses for quite a while now.

An example that was caught by KASAN:

60a9432454 drm/i915/execlists: Drop clear_gtiir() on GPU reset
With the new CSB processing code, we are not vulnerable to delayed
delivery of a pre-reset interrupt as we use the CSB status pointers in
the HWSP to decide if we need to parse any CSB events and no longer need
to wait for the first post-reset interrupt to be assured that the CSB
mmio registers are valid.

The new icl code to clear registers has a nasty lock inversion:

9701975e85 drm/i915: Do not short-circuit tasklets during reset
Inside intel_engine_is_idle(), we flush the tasklet to ensure that is
being run in a timely fashion (ksoftirqd has taught us to expect the
worst). However, if we are in the middle of reset, the HW may not yet be
ready to execute the submission tasklet and so we must respect the
disable flag.

8725aecac3 drm/amdkfd: Workaround to accommodate Raven too many PPR issue
On Raven multiple PPRs can be queued up by the hardware. When the
first of those requests is handled by the IOMMU driver, the memory
access succeeds. After that the application may be done with the
memory and unmap it. At that point the page table entries are
invalidated, but there are still outstanding duplicate PPRs for those
addresses. When the IOMMU driver processes those duplicate requests,
it finds invalid page table entries and triggers an invalid PPR fault.

As a workaround, don't signal invalid PPR faults on Raven to avoid
segfaulting applications that haven't done anything wrong. As a side
effect, real GPU memory access faults may go unnoticed by the
application.

edf6ffe4f4 drm/amd/display: Read AUX channel even if only status byte is returned
[Why]
get_channel_status() can return 0 in returned_bytes, and report a
successful operation result. This is because it prunes the first status
byte out. This was preventing read_channel_reply() from being called
(due to the faulty condition), and consequently preventing the AUX
reply status from being set.

[How]
Fix the conditional so that it accounts for when get_channel_status()
returns 0 bytes read.

Fixes possible edid read failures during S3 resume, where we are now
relying on DRM's DP AUX handling. This was an regression introduced by:

 --- HPD detection is disabled when set PHY test pattern

  when PHY test pattern (pattern # within [1,7]) is set, HPD pin of
  HW ASIC is disable. User could unplug DP display from DP connected
  and plug scope to check test pattern PHY SI.
  If there is need unplug scope and plug DP display back, do steps
  below:
  echo 0 > phy_test_pattern
  unplug scope
  plug DP display.

  "echo 0 > phy_test_pattern" will re-enable HPD pin again so that
  video sw driver could detect "unplug scope" and "plug DP display"

084b3765ec drm/amd/display: Return aux replies directly to DRM
Currently we still go through DC code that does error checking, retries,
etc. There's no need for that since DRM already does that for us. This
simplifies the code a bit and makes it easier to debug.

This also ensures we correctly tell DRM how many bytes have actually
been read, as we should. This allows DRM to correctly read the EDID on
the Chamelium DP port.

Rather than using the index variable stored in vram.  If
the device fails to come back online after a resume cycle,
reads from vram will return all 1s which will cause a

This avoids the segfault, but we still need to sort out

af92058ff0 drm/i915: Pass hpd_pin to long_pulse_detect()
We're doing a pointless translation from hpd_pin to port simply for
passing the thing to long_pulse_detect(). Let's pass the hpd_pin
directly instead.

This removes the assumption that the hpd_pin and port always
match. The only other place where we make that assumption anymore
is intel_hpd_pin_default() and that's fine as it's what determines
the relationship between the two. If we ever get hardware where
the hpd pins are wired in more interesting ways it should be
trivial to handle from now on.

This should also fix the IS_CNL_WITH_PORT_F() case as that mapped
pin E back to port F and passed that to
spt_port_hotplug2_long_detect() which would always return false
for port F. Now that we pass in pin E directly it'll actually
do the right thing.

This adds support for the DisplayPort CEC-Tunneling-over-AUX

Unfortunately, not all DisplayPort/USB-C to HDMI adapters with a

even though a CEC device is created, it may not actually work.

90c3e21987 drm/i915/glk: Add Quirk for GLK NUC HDMI port issues.
On GLK NUC platforms the HDMI retiming buffer needs additional disabled
time to correctly sync to a faster incoming signal.

When measured on a scope the highspeed lines of the HDMI clock turn off
 for ~400uS during a normal resolution change. The HDMI retimer on the
 GLK NUC appears to require at least a full frame of quiet time before a
new faster clock can be correctly sync'd. Wait 100ms due to msleep
inaccuracies while waiting for a completed frame. Add a quirk to the
driver for GLK boards that use ITE66317 HDMI retimers.

V2: Add more devices to the quirk list
V3: Delay increased to 100ms, check to confirm crtc type is HDMI.
V4: crtc type check extended to include _DDI and whitespace fixes
v5: Fix white spaces, remove the macro for delay. Revert the crtc type
    check introduced in v4.

And it was actually masking another bug fixed by commit

So, let's remove these options for now. End goal is to

c3d433617d drm/i915: Use crtc_state->has_psr instead of CAN_PSR for pipe update
In commit "drm/i915: Wait for PSR exit before checking for vblank
evasion", the idea was to limit the PSR IDLE checks when PSR is
actually supported. While CAN_PSR does do that check, it doesn't
applies on a per-crtc basis. crtc_state->has_psr is a more granular
check that only applies to pipe(s) that have PSR enabled.

Without the has_psr check, we end up waiting on the eDP transcoder's
PSR_STATUS register irrespective of whether the pipe being updated is
driving it or not.

v2: Remove unnecessary parantheses, make checkpatch happy.

v3: Move the has_psr check to intel_psr_wait_for_idle and commit
    message changes (DK).

v4: Derive dev_priv from intel_crtc_state (DK)

v5: Commit message changes to reflect the HW behavior (DK)

drm/sun4i: tcon-top: Fix return type warning
When commit af11942ee4 ("drm/sun4i: tcon-top: Cleanup clock handling")
was merged, the error handling path of the of_property_match_string was
changed to take into account the fact that the returned value of that
function wasn't an error pointer but an error code.

Unfortunately, this introduced a warning since the now returned value is an
integer, while the sun8i_tcon_top_register_gate function should return an
error pointer.

Fix that by calling ERR_PTR.

drm/sun4i: Implement zpos for DE2
Initial implementation of DE2 planes only supported fixed zpos.

Expand implementation with configurable zpos property.

Implementation background:
Channel in DE2 driver represents one DRM plane, whereas pipe is just
mapped channel to known Z position. Pipe 0 will always be at the bottom,
pipe 1 just above pipe 0 and so on. If, for example, channel 1 is mapped
at pipe 0 and channel 0 at pipe 1, whatever is on channel 0 will appear
on top.

Before this commit, channel id was used for addressing channel related
registers (prefixed with SUN8I_MIXER_CHAN_UI_ or SUN8I_MIXER_CHAN_VI_)
and pipe registers (prefixed with SUN8I_MIXER_BLEND_). Additionally,
register SUN8I_MIXER_BLEND_ROUTE, which takes care for mapping channels
to pipes had fixed value. It mapped channel 0 to pipe 0, 1 to 1 and so
on. Consequence of all that was fixed Z order of planes.

With this commit, pipe registers are using zpos property as index and
channel related registers still use channel id as index. Pipe mapping
register is now set dynamically too and pipe enable register is rebuild
every time to make sure only active pipes are enabled.

Testing was done to confirm that there is no issues if bottom plane
contains pixels with alpha value < 0xff and if it doesn't whole screen.

they were found to be the same, and so the clock was not set.
This resulted in a pernicious blackscreen.

[How]
In atomic commit, check to see if there are any active pipes.
If no, set clocks to 0

d89d01f223 drm/amd/display: Convert 10kHz clks from PPLib into kHz for Vega
The driver is expecting clock frequency in kHz, while SMU returns
the values in 10kHz, which causes the bandwidth validation to fail

4.18 has the faulty clock assignment in pp_to_dc_clock_levels_with_latency
only, which is only used by Vega. Make sure we multiply these values
by 10 here, as we do for other ASICs as powerplay assigned them
wrong. 4.19 has the proper fix in powerplay.

a63983f260 drm/i915/selftests: Fixup GuC FW negative test
Since:
0d4b78b3d2 ("drm/i915/guc: Assert we have the doorbell before setting it up")

We have asserts in GuC doorbell related functions, which is a good thing.
Unfortunately, we were using those to check whether GuC FW is refusing
to allocate invalid doorbell - which makes the test fail.
Well, it would make the test WARN, except we fumbled cleanup ordering
and eat the BUG_ON instead.
Let's keep the asserts and use the internal implementation in the test.

drm/sun4i: fix build failure with CONFIG_DRM_SUN8I_MIXER=m
Having DRM_SUN4I built-in but DRM_SUN8I_MIXER as a loadable module results in
a link error, as we try to access a symbol from the sun8i_tcon_top.ko module:

ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun8i-drm-hdmi.ko] undefined!
ERROR: "sun8i_tcon_top_of_table" [drivers/gpu/drm/sun4i/sun4i-drm.ko] undefined!

This solves the problem by adding a silent symbol for the tcon_top module,
building it as a separate module in exactly the cases that we need it,
but in a way that it is reachable by the other modules.

drm/sun4i: mixer: Read id from DT
Currently, TCON supports 2 ways to match TCON with engine (mixer in this
case). Old way is to just traverse of graph backwards and compare node
pointer. New way is to match TCON and engine by their respective ids.
All SoCs with DE2 enabled till now used the old way, which means mixer
id was never used and thus never implemented.

However, for R40, only the new way will be used. To prepare for that,
implement mixer id fetching from DT.

3a0709928b drm/vkms: Add vblank events simulated by hrtimers
This commit adds regular vblank events simulated through hrtimers, which
is a feature required by VKMS to mimic real hardware. Additionally, all
the vblank event send after pageflip is kept in the atomic_flush
function.

Changes since V1:
 - Compute the vblank timer interval per interruption
 Ville Syrjälä and Daniel Vetter:
 - Removes hardcoded vblank interval to get it from user space

Changes since V2:
 Chris Wilson
 - Removes unnecessary algorithm to compute the next period
 Daniel Vetter:
 - Uses drm_calc_timestamping_constants to get the vblank interval
   instead of calculating it manually
 - Adds disable_vblank helper that turns of crtc
 - Simplifies implementation by using drm_crtc_arm_vblank_event
 - Replaces the code in atomic_begin to atomic_flush
 - Removes unnecessary field in vkms_output

Changes since V3:

 - Squash "drm/vkms: Add atomic helpers functions" into the commit that
   handling vblank events simulated by hrtimers

Remove the requirement that DRM should be registered when creating a

89c815ef07 drm/ttm: Introduce ttm_bo_get() and ttm_bo_put() for ref counting
The TTM buffer-object interface provides ttm_bo_reference() and
ttm_bo_unref() for managing reference counts. Replacing them with
ttm_bo_get() and ttm_bo_put() aligns the API with conventions used
throughout the Linux kernel.

The implementation of ttm_bo_unref() clears the supplied pointer
to NULL. This leads to workarounds where the caller saves the
pointer's value before de-referencing the BO. ttm_bo_put() does
not clear the supplied pointer.

c59eb3cfde drm/panel: Let of_drm_find_panel() return -ENODEV when the panel is disabled
DT nodes might be present in the DT but with a status property set to
"disabled" or "fail". In this case, we should not return -EPROBE_DEFER
when the caller asks for a drm_panel instance. Return -ENODEV instead.

5fa8e4a221 drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULL
Right now, the DRM panel logic returns NULL when a panel pointing to
the passed OF node is not present in the list of registered panels.

Most drivers interpret this NULL value as -EPROBE_DEFER, but we are
about to modify the semantic of of_drm_find_panel() and let the
framework return -ENODEV when the device node we're pointing to has
a status property that is not equal to "okay" or "ok".

Let's first patch the of_drm_find_panel() implementation to return
ERR_PTR(-EPROBE_DEFER) instead of NULL and patch all callers to replace
the '!panel' check by an 'IS_ERR(panel)' one.

894a677f4b drm/cma-helper: Use the generic fbdev emulation
This switches the CMA helper drivers that use its fbdev emulation over
to the generic fbdev emulation. It's the first phase of using generic
fbdev. A later phase will use DRM client callbacks for the
lastclose/hotplug/remove callbacks.

There are currently 2 fbdev init/fini functions:
- drm_fb_cma_fbdev_init/drm_fb_cma_fbdev_fini
- drm_fbdev_cma_init/drm_fbdev_cma_fini

This is because the work on generic fbdev came up during a fbdev
refactoring and thus wasn't completed. No point in completing that
refactoring when drivers will soon move to drm_fb_helper_generic_probe().

tinydrm uses drm_fb_cma_fbdev_init_with_funcs().

c76f0f7cb5 drm: Begin an API for in-kernel clients
This the beginning of an API for in-kernel clients.
First out is a way to get a framebuffer backed by a dumb buffer.

Only GEM drivers are supported.
The original idea of using an exported dma-buf was dropped because it
also creates an anonomous file descriptor which doesn't work when the
buffer is created from a kernel thread. The easy way out is to use
drm_driver.gem_prime_vmap to get the virtual address, which requires a
GEM object. This excludes the vmwgfx driver which is the only non-GEM
driver apart from the legacy ones. A solution for vmwgfx will have to be
worked out later if it wants to support the client API which it probably
will when we have a bootsplash client.

Across a reset, the seqno (and thus hangcheck) should restart and the

do not detect if the call to reinit succeeds but the HW is fried - as we
are resetting hangcheck on initialisation the engine. Remove that and
rely on the natural progress to reset the hangcheck timer.

cecb368d2f drm/i915/selftests: Filter out both physical address swizzles
In our swizzling selftests, we cannot predict the physical address of
the target page (at least not simply!) and so skip bit17 swizzles.
However, there are two bit17 swizzle modes and we only skipped one, with
the second being observed on the lab gdg causing the test to fail,
as soon as we hit a page with bit17 set in its address.

ebfa7944d6 drm/i915/selftests: Constrain mock_gtt tests to fit within RAM
Be pessimistic and presume that we actually allocate every page we
exercise via the mock_gtt (e.g. for gvt). In which case we have to keep
our working set under the available physical memory to prevent oom.

8cff1f4a3c drm/i915: Remove function details from device error messages
Error messages are intended to be addressed to the user; be clear,
succinct, instructive and unambiguous. Adding the function name to
that message does not add any information the user requires and in
the process makes the message less clear.

E.g.

[  245.539711] i915 0000:00:02.0: [drm:i915_gem_init [i915]] Failed to initialize GPU, declaring it wedged!

96a85cc517 drm/i915: Fix hotplug irq ack on i965/g4x
Just like with PIPESTAT, the edge triggered IIR on i965/g4x
also causes problems for hotplug interrupts. To make sure
we don't get the IIR port interrupt bit stuck low with the
ISR bit high we must force an edge in ISR. Unfortunately
we can't borrow the PIPESTAT trick and toggle the enable
bits in PORT_HOTPLUG_EN as that act itself generates hotplug
interrupts. Instead we just have to loop until we've cleared
PORT_HOTPLUG_STAT, or we just give up and WARN.

v2: Don't frob with PORT_HOTPLUG_EN

932cac10c8 drm/i915/selftests: Prevent background reaping of active objects
igt_mmap_offset_exhaustion() wants to test what happens when the mmap
space is filled with zombie objects, objects discarded by userspace but
still active on the GPU. As they are only protected by the active
reference, we have to be certain that active reference is kept while we
peek into our dangling pointer. That active reference should not be
freed until we retire, but we do that retirement from a background
thread. This leaves us with a subtle timing problem, exacerbated and
highlighted by KASAN:

2621cefaa4 drm/i915: Provide a timeout to i915_gem_wait_for_idle() on setup
With a broken GPU we expect it to fail during the initial
GPU setup where do a couple of context switches to record the defaults.
This is a task that takes a few milliseconds even on the slowest of
devices, but we may have to wait 60s for hangcheck to give in and
declare the machine inoperable. In this a case where any gpu hang is
unacceptable, both from a timeliness and practical standpoint.

We can therefore set a timeout on our wait-for-idle that is shorter than
the hangcheck (which may be up to 60s for a declaring a wedged driver)
and so detect the broken GPU much more quickly during driver load (and
so prevent stalling userspace for ages).

ec625fb932 drm/i915: Provide a timeout to i915_gem_wait_for_idle()
Usually we have no idea about the upper bound we need to wait to catch
up with userspace when idling the device, but in a few situations we
know the system was idle beforehand and can provide a short timeout in
order to very quickly catch a failure, long before hangcheck kicks in.

In the following patches, we will use the timeout to curtain two overly
long waits, where we know we can expect the GPU to complete within a
reasonable time or declare it broken.

In particular, with a broken GPU we expect it to fail during the initial
GPU setup where do a couple of context switches to record the defaults.
This is a task that takes a few milliseconds even on the slowest of
devices, but we may have to wait 60s for hangcheck to give in and
declare the machine inoperable. In this a case where any gpu hang is
unacceptable, both from a timeliness and practical standpoint.

The other improvement is that in selftests, we do not need to arm an
independent timer to inject a wedge, as we can just limit the timeout on
the wait directly.

v2: Include the timeout parameter in the trace.

b25c60af7a drm/crtc: Add a generic infrastructure to fake VBLANK events
In some cases CRTCs are active but are not able to generating events, at
least not at every frame at it's expected to.
This is typically the case when the CRTC is feeding a writeback connector
that has no job queued. In this situation the CRTC is usually stopped
until a new job is queued, and this can lead to timeouts when part of
the pipeline is updated but no new jobs are queued to the active
writeback connector.

In order to solve that, we add a ->no_vblank flag to drm_crtc_state
and ask the CRTC drivers to set it to true when they know they're not
able to generate VBLANK events. The core drm_atomic_helper_fake_vblank()
helper can then be used to fake VBLANKs at commit time.

184d3cf4f7 drm/vc4: Use wait_for_flip_done() instead of wait_for_vblanks()
drm_atomic_helper_wait_for_vblanks() assumes the CRTC will continuously
generate VBLANK events and the vblank counter will keep increasing.
While this work for a regular pipeline, it doesn't when you have the
CRTC is feeding the transposer block, because this block works in
oneshot mode, and, by the time we reach
drm_atomic_helper_wait_for_vblanks() the only VBLANK event might have
already been sent and the VBLANK counter will stay unchanged, thus
triggering a timeout.

Luckily, we can replace the drm_atomic_helper_wait_for_vblanks() call
by drm_atomic_helper_wait_for_flip_done() because the only thing we
want to check when calling drm_atomic_helper_wait_for_vblanks() from

8b293eb53a drm/i915: Track the last-active inside the i915_vma
Using a VMA on more than one timeline concurrently is the exception
rather than the rule (using it concurrently on multiple engines). As we
expect to only use one active tracker, store the most recently used
tracker inside the i915_vma itself and only fallback to the rbtree if
we need a second or more concurrent active trackers.

v2: Comments on how we overwrite any existing last_active cache.
v3: __list_del_entry() before list_replace_init() is confusing and, much
more important, entirely redundant.
v4: Note that both last_active and the rbtree may be simultaneously
tracking this timeline, albeit with different requests, and so the vma
may be retired twice for the same timeline.
v5: No, that list_del is required!

5c3f8c221c drm/i915: Track vma activity per fence.context, not per engine
In the next patch, we will want to be able to use more flexible request
timelines that can hop between engines. From the vma pov, we can then
not rely on the binding of this request to an engine and so can not
ensure that different requests are ordered through a per-engine
timeline, and so we must track activity of all timelines. (We track
activity on the vma itself to prevent unbinding from HW before the HW
has finished accessing it.)

v2: Switch to a rbtree for 32b safety (since using u64 as a radixtree
index is fraught with aliasing of unsigned longs).
v3: s/lookup_active/active_instance/ because we can never agree on names

b79ebe74e1 drm/i915/ddi: Simplify get_encoder_power_domains()
We can simplify the encoder's get_power_domains() hook by calling it
only if the encoder is active. That way the hook can return its power
domains unconditionally without checking the active state by calling
encoder::get_hw_state(). This get_hw_state() query is in fact
redundant since it's already done by intel_modeset_readout_hw_state()
setting the encoder's crtc or leaving it NULL accordingly. Let's use
this fact to decide if the encoder is active.

While at it clarify the comment in intel_ddi_get_power_domains() about
primary vs. fake MST encoders and make sure we never do an incorrect
encoder->dig_port cast for fake MST encoders.

b5f6e53d4c drm/i915/selftests: Skip using the GPU if wedged
If the GPU is irrecoverably broken, we can not use it to dirty memory
and check for cache coherency with the CPU. All we can do is simply skip
over the GPU subtests and focus on the CPU domains (WC, WB) cache
management.

e5d2435bfa drm/i915/selftests: Destroy partial tiling vma after use
As we keep VMA around until the object is destroyed, when testing
partial tiling we instantiate many, many VMA (as the object is huge
allowing for many different partial regions). We test elsewhere our
handling of populating large objects with a full set of VMA and checking
we can retrieve them afterwards, but in this test we incur the cost of
flushing all VMA after every GTT write, dramatically slowing down the
test.

e518634b43 drm/i915/dsi: use vlv and bxt prefixes for the global DSI functions
Avoid confusion with the functions to be added for the new ICL or gen 11
DSI implementation by renaming the current DSI functions. While at it,
permutate the words in the function names to make them all start with
"vlv_dsi" or "vlv_dsi_pll" etc.

Reduce the platform abstractions in the PLL file while at it, moving the
checks to vlv_dsi.c instead, where we typically already have the
necessary if ladders.

Leave the static functions as-is for now; they could be renamed later if
needed.

No functional changes.

v2: use "gen7" prefix.

v3: use "vlv" and "bxt" prefixes, reduce the abstractions.

Adding a helper function that would verify if the display depth
assigned would pass a bandwidth validation.

6f3472a993 drm/amd/display/dc/dce: Fix multiple potential integer overflows
Add suffix ULL to constant 5 and cast variables target_pix_clk_khz and
feedback_divider to uint64_t in order to avoid multiple potential integer
overflows and give the compiler complete information about the proper
arithmetic to use.

Notice that such constant and variables are used in contexts that
expect expressions of type uint64_t (64 bits, unsigned). The current
casts to uint64_t effectively apply to each expression as a whole,
but they do not prevent them from being evaluated using 32-bit
arithmetic instead of 64-bit arithmetic.

Also, once the expressions are properly evaluated using 64-bit
arithmentic, there is no need for the parentheses that enclose
them.

280cf1a94b drm/amdgpu: Dynamically probe for ATIF handle (v2)
The other day I was testing one of the HP laptops at my office with an
i915/amdgpu hybrid setup and noticed that hotplugging was non-functional
on almost all of the display outputs. I eventually discovered that all
of the external outputs were connected to the amdgpu device instead of
i915, and that the hotplugs weren't being detected so long as the GPU
was in runtime suspend. After some talking with folks at AMD, I learned
that amdgpu is actually supposed to support hotplug detection in runtime
suspend so long as the OEM has implemented it properly in the firmware.

On this HP ZBook 15 G4 (the machine in question), amdgpu wasn't managing
to find the ATIF handle at all despite the fact that I could see acpi
events being sent in response to any hotplugging. After going through
dumps of the firmware, I discovered that this machine did in fact
support ATIF, but that it's ATIF method lived in an entirely different
namespace than this device's handle (the device handle was
\_SB_.PCI0.PEG0.PEGP, but ATIF lives in ATPX's handle at
\_SB_.PCI0.GFX0).

So, fix this by probing ATPX's ACPI parent's namespace if we can't find
ATIF elsewhere, along with storing a pointer to the proper handle to use
for ATIF and using that instead of the device's handle.

This fixes HPD detection while in runtime suspend for this ZBook!

v2: Update the comment to reflect how the namespaces are arranged
based on the system configuration. (Alex)

102c16a024 drm/amdgpu: Make struct amdgpu_atif private to amdgpu_acpi.c
Currently, there is nothing in amdgpu that actually uses these structs
other than amdgpu_acpi.c. Additionally, since we're about to start
saving the correct ACPI handle to use for calling ATIF in this struct
this saves us from having to handle making sure that the acpi_handle
(and by proxy, the type definition for acpi_handle and all of the other
acpi headers) doesn't need to be included within the amdgpu_drv struct
itself. This follows the example set by amdgpu_atpx_handler.c.

f3e077d95c drm/amd/display: fix use of uninitialized memory
DML does not calculate chroma values for RQ when surface is not YUV, but DC
will unconditionally use the uninitialized values for HW programming.
This does not cause visual corruption since HW will ignore garbage chroma
values when surface is not YUV, but causes presubmission tests to fail
golden value comparison.

9bdc2092b4 drm/amdgpu: Add parsing SQ_EDC_INFO to SQ IH v3.
Access to SQ_EDC_INFO requires selecting register instance and
hence mutex lock when accessing GRBM_GFX_INDEX for which a work
is schedueled from IH. But SQ interrupt can be raised on many instances
at once which means queuing work will usually succeed for the first one
but fail for the rest since the work takes time to process. To avoid
losing info about other interrupt instances call the parsing function
directly from high IRQ when current work hasn't finished and avoid
accessing SQ_EDC_INFO in that case.

v2:
Simplify high IRQ and BH handlers synchronization using work_pending.
Remove {READ,WRITE}_ONCE notations since smp_{r,w}mb are implicit
compiler barriers.

v3:
Remove exlicit memory barriers as scedule_work has r/w barriers.

73d8e5fba5 drm/i915/selftests: Detect unknown swizzling correctly
i915_gem_detect_bit_6_swizzle() tries to hide unknown swizzling from
userspace (and ourselves) leaving us with the only clue inside
i915->quirks & QUIRK_PIN_SWIZZLED_PAGES. If we see this bit set, it
means that we really have no clue as to what the swizzle pattern is
being used in any one page and so cannot compute what the reference
value should be in our tiling selftests. We have to skip the test.

e368fc75c1 drm/arm/malidp: Added the late system pm functions
malidp_pm_suspend_late checks if the runtime status is not suspended
and if so, invokes malidp_runtime_pm_suspend which disables the
display engine/core interrupts and the clocks. It sets the runtime status
as suspended.

The difference between suspend() and suspend_late() is as follows:-
1. suspend() makes the device quiescent. In our case, we invoke the DRM
helper which disables the CRTC. This would have invoked runtime pm
suspend but the system suspend process disables runtime pm.
2. suspend_late() It continues the suspend operations of the drm device
which was started by suspend(). In our case, it performs the same functionality
as runtime_suspend().

The complimentary functions are resume() and resume_early(). In the case of
resume_early(), we invoke malidp_runtime_pm_resume() which enables the clocks
and the interrupts. It sets the runtime status as active. If the device was
in runtime suspend mode before system suspend was called, pm_runtime_work()
will put the device back in runtime suspended mode( after the complete system
has been resumed).

613c5c7fc8 drm: mali-dp: Add debugfs file for reporting internal errors
Status register contains a lot of bits for reporting internal errors
inside Mali DP. Currently, we just silently ignore all of the errors,
that doesn't help when we are investigating different bugs, especially
on the FPGA models which have a lot of constraints, so we could easily
end up in AXI or underrun errors.

Add a new file called debug that contains an aggregate of the
errors reported by the Mali DP hardware.

E.g:
[root@alarm ~]# cat /sys/kernel/debug/dri/1/debug
[DE] num_errors : 167
[DE] last_error_status  : 0x00000001
[DE] last_error_vblank : 385
[SE] num_errors : 3
[SE] last_error_status  : 0x00e23001
[SE] last_error_vblank : 201

Changes since v2:
- Add lock to protect the errors stats.
- Add possibility to reset the error stats by writing anything to the
  debug file.

0735cfdf0a drm/mali-dp: Improve writeback handling for DP500.
Mali DP500 operates in continuous writeback mode (writes frame content
until stopped) and it needs special handling in order to behave like
a one-shot writeback engine. The original state machine added for DP500
was a bit fragile, as it did not handle correctly cases where a new
atomic commit was in progress when the SE IRQ happens and it would
commit some partial updates.

Improve the handling by adding a parameter to the set_config_valid()
function to clear the config valid bit in hardware before starting a
new commit and by introducing a MW_RESTART state in the writeback
state machine to cater for the case where a new writeback commit
gets submitted while the last one is still being active.

1cb3cbe732 drm/mali-dp: Add writeback support for DP500.
Mali DP500 behaves differently from the rest of the Mali DP IP,
in that it does not have a one-shot mode and keeps writing the
content of the current frame to the provided memory area until
stopped. As a way of emulating the one-shot behaviour, we are
going to use the CVAL interrupt that is being raised at the
start of each frame, during prefetch phase, to act as End-of-Write
signal, but with a twist: we are going to disable the memory
write engine right after we're notified that it has been enabled,
using the knowledge that the bit controlling the enabling will
only be acted upon on the next vblank/prefetch.

CVAL interrupt will fire durint the next prefetch phase every time
the global CVAL bit gets set, so we need a state byte to track
the memory write enabling. We also need to pay attention during the
disabling of the memory write engine as that requires the CVAL bit
to be set in the control register, but we don't want to do that
during an atomic commit, as it will write into the hardware a partial
state.

1c7c5fd916 drm/vkms: Introduce basic VKMS driver
This patch introduces Virtual Kernel Mode-Setting (VKMS) driver. It
creates a very basic kms driver with 1 crtc/encoder/connector/plane.

VKMS driver would be useful for testing, or for running X (or similar)
on headless machines and be able to still use the GPU. Thus it enables
a virtual display without the need for hardware display capability.

2c83a726d6 drm/etnaviv: bring back progress check in job timeout handler
When the hangcheck handler was replaced by the DRM scheduler timeout
handling we dropped the forward progress check, as this might allow
clients to hog the GPU for a long time with a big job.

It turns out that even reasonably well behaved clients like the
Armada Xorg driver occasionally trip over the 500ms timeout. Bring
back the forward progress check to get rid of the userspace regression.

We would still like to fix userspace to submit smaller batches
if possible, but that is for another day.

99ec9e7751 drm/udl: fix display corruption of the last line
The displaylink hardware has such a peculiarity that it doesn't render a
command until next command is received. This produces occasional
corruption, such as when setting 22x11 font on the console, only the first
line of the cursor will be blinking if the cursor is located at some
specific columns.

When we end up with a repeating pixel, the driver has a bug that it leaves
one uninitialized byte after the command (and this byte is enough to flush
the command and render it - thus it fixes the screen corruption), however
whe we end up with a non-repeating pixel, there is no byte appended and
this results in temporary screen corruption.

This patch fixes the screen corruption by always appending a byte 0xAF at
the end of URB. It also removes the uninitialized byte.

63fd659fb1 drm/i915/gtt: Pull global wc page stash under its own locking
Currently, the wc-stash used for providing flushed WC pages ready for
constructing the page directories is assumed to be protected by the
struct_mutex. However, we want to remove this global lock and so must
install a replacement global lock for accessing the global wc-stash (the
per-vm stash continues to be guarded by the vm).

We need to push ahead on this patch due to an oversight in hastily
removing the struct_mutex guard around the igt_ppgtt_alloc selftest. No
matter, it will prove very useful (i.e. will be required) in the near
future.

v2: Restore the onstack stash so that we can drop the vm->mutex in
future across the allocation.
v3: Restore the lost pagevec_init of the onstack allocation, and repaint
function names.
v4: Reorder init so that we don't try and use i915_address_space before
it is ininitialised.

Adjust the EIR clearing to cope with the edge triggered IIR

we temporarily mask everything in EMR. As some of the EIR bits
can't even be directly cleared we also borrow a trick from
i915_clear_error_registers() and permanently mask any bit that
remains high. No real thought given to how we might unmask them
again once the cause for the error has been clered. I suppose
on pre-g4x GPU reset will reinitialize EMR from scratch.

38b7fb0b2a drm/i915/selftests: Release the struct_mutex to free the objects
live_gtt is a very slow test to run, simply because it tries to allocate
and use as much as the 48b address space as possibly can and in the
process will try to own all of the system memory. This leads to resource
exhaustion and CPU starvation; the latter impacts us when the NMI
watchdog declares a task hung due to a mutex contention with ourselves.
This we can prevent by releasing the struct_mutex and forcing our
i915/rcu workers to run, and in particular flushing the freed object
worker that is the cause for concern.
