Entity currently keeps a copy of run_queue list and modify it in
drm_sched_entity_set_priority(). Entities shouldn't modify run_queue
list. Use drm_gpu_scheduler list instead of drm_sched_rq list
in drm_sched_entity struct. In this way we can select a runqueue based

Annoyingly __drm_atomic_helper_crtc_reset() does two
totally separate things:
a) reset the state to defaults values
b) assign the crtc->state pointer
I just want a) without the b) so let's split out part
a) into __drm_atomic_helper_crtc_state_reset(). And
of course we'll do the same thing for planes and connectors.

An LVDS dual-link connection is made of two links, with even
pixels transitting on one link, and odd pixels on the other
link. The device tree can be used to fully describe dual-link
LVDS connections between encoders and bridges/panels.
The sink of an LVDS dual-link connection is made of two ports,
the corresponding OF graph port nodes can be marked
with either dual-lvds-even-pixels or dual-lvds-odd-pixels,
and that fully describes an LVDS dual-link connection,
including pixel order.
drm_of_lvds_get_dual_link_pixel_order is a new helper
added by this patch, given the source port nodes it
returns DRM_LVDS_DUAL_LINK_EVEN_ODD_PIXELS if the source
port nodes belong to an LVDS dual-link connection, with even
pixels expected to be generated from the first port, and odd
pixels expected to be generated from the second port.
If the new helper returns DRM_LVDS_DUAL_LINK_ODD_EVEN_PIXELS,
odd pixels are expected to be generated from the first port,
and even pixels from the other port.

Add new struct drm_device based logging macros modeled after the core
kernel device based logging macros. These would be preferred over the
drm printk and struct device based macros in drm code, where possible.
We have existing drm specific struct device based logging functions, but
they are too verbose to use for two main reasons:
* The names are unnecessarily long, for example DRM_DEV_DEBUG_KMS().
* The use of struct device over struct drm_device is too generic for
most users, leading to an extra dereference.
For example:
DRM_DEV_DEBUG_KMS(drm->dev, "Hello, world\n");
vs.
drm_dbg_kms(drm, "Hello, world\n");
It's a matter of taste, but the SHOUTING UPPERCASE has been argued to be
less readable than lowercase.
Some names are changed from old DRM names to be based on the core kernel
logging functions. For example, NOTE -> notice, ERROR -> err, DEBUG ->
dbg.
Due to the conflation of DRM_DEBUG and DRM_DEBUG_DRIVER macro use
(DRM_DEBUG is used widely in drivers though it's supposed to be a core
debugging category), they are named as drm_dbg_core and drm_dbg,
respectively.
The drm_err and _once/_ratelimited variants no longer include the
function name in order to be able to use the core device based logging
macros. Arguably this is not a significant change; error messages should
not be so common to be only distinguishable by the function name.
Ratelimited debug logging macros are to be added later.

Sometimes we want to override a connector's panel_orientation from the
kernel commandline. Either for testing and for special cases, e.g. a kiosk
like setup which uses a TV mounted in portrait mode.
Users can already specify a "rotate" option through a video= kernel cmdline
option. But that only supports 0/180 degrees (see drm_client_modeset TODO)
and only works for in kernel modeset clients, not for userspace kms users.
The "panel-orientation" connector property OTOH does support 90/270 degrees
as it leaves dealing with the rotation up to userspace and this does work
for userspace kms clients (at least those which support this property).

-Add missing ':' after @panel_orientation (reported by kbuild test robot)

The timing values for dw-dsi are often dependent on the used display and
according to Philippe Cornu will most likely also depend on the used phy
technology in the soc-specific implementation.
To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.
Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling
according to the phy speed, while STM seems to be ok with static values.

The panel drivers used drm_panel.drm for two purposes:
1) Argument to drm_mode_duplicate()
2) drm->dev was used in error messages
The first usage is replaced with drm_connector.dev
- drm_connector is already connected to a drm_device
and we have a valid connector
The second usage is replaced with drm_panel.dev
- this makes drivers more consistent in their dev argument
used for dev_err() and friends
With these replacements there are no more uses of drm_panel.drm,
so it is removed from struct drm_panel.
With this change drm_panel_attach() and drm_panel_detach()
no longer have any use as they are empty functions.

Panels often support backlight as specified in a device tree.
Update the drm_panel infrastructure to support this to
simplify the drivers.
With this the panel driver just needs to add the following to the
probe() function:
err = drm_panel_of_backlight(panel);
if (err)
return err;
Then drm_panel will handle all the rest.
There is one caveat with the backlight support.
If drm_panel_(enable|disable) are called multiple times
in a row then backlight_(enable|disable) will be called multiple times.
The above will happen when a panel drivers unconditionally
calls drm_panel_disable() in their shutdown() function,
whan the panel is already disabled and then shutdown() is called.
Reading the backlight code it seems safe to call
the backlight_(enable|disable) several times.
v3:
- Improve comments, fix grammar (Laurent)

We are about to replace the single-linked bridge list by a double-linked
one based on list.h, leading to the suppression of the encoder->bridge
field. But before we can do that we must provide a
drm_bridge_chain_get_first_bridge() bridge helper and patch all drivers
and core helpers to use it instead of directly accessing encoder->bridge.
Note that we still have 2 drivers (VC4 and Exynos) manipulating the
encoder->bridge field directly because they need to cut the bridge chain
in order to control the enable/disable sequence. This is definitely
not something we want to encourage, so let's keep those 2 oddities
around until we find a better solution.

The fake offset is going to stay, so change the calling convention for
drm_gem_object_funcs.mmap to include the fake offset. Update all users
accordingly.
Note that this reverts 83b8a6f242 ("drm/gem: Fix mmap fake offset
handling for drm_gem_object_funcs.mmap") and on top then adds the fake
offset to drm_gem_prime_mmap to make sure all paths leading to
obj->funcs->mmap are consistent.
v3: move fake-offset tweak in drm_gem_prime_mmap() so we have this code
only once in the function (Rob Herring).

It seems that on certain MST hubs, namely the CableMatters USB-C 2x DP
hub, using the DP_PAYLOAD_ALLOCATE_SET and DP_PAYLOAD_TABLE_UPDATE_STATUS
register ranges to clear any pre-existing payload allocations on the hub isn't
always enough to reset things if the source device has been reset unexpectedly.
Or at least, that's the current running theory. The precise behavior appears to
be that when the source device gets reset unexpectedly, the hub begins reporting
an available_pbn value of 0 for all of its ports. This is a bit inconsistent
with the our theory, since this seems to happen even if previously set PBN
allocations should have resulted in a non-zero available_pbn value. So, it's
possible that something else may be going on here.
Strangely though, sending a CLEAR_PAYLOAD_ID_TABLE broadcast request when
initializing the MST topology seems to bring things into working order and make
available_pbn work again. Since this is a pretty safe solution, let's go ahead
and implement it.
Changes since v1:
* Change indenting on drm_dp_send_clear_payload_id_table() prototype
* Remove some braces in drm_dp_send_clear_payload_id_table()
* Reorganize some variable declarations in drm_dp_send_clear_payload_id_table()
* Don't forget to handle DP_CLEAR_PAYLOAD_ID_TABLE in
drm_dp_sideband_parse_reply()
* Move drm_dp_send_clear_payload_id_table() call into
drm_dp_mst_link_probe_work(), since we can't send sideband messages
while under lock in drm_dp_mst_topology_mgr_set_mst()
* Change commit message

This thing can get called several thousand times per LUT
so seems like we want to inline it to:
- avoid the function call overhead
- allow constant folding
A quick synthetic test (w/o any hardware interaction) with
a ridiculously large LUT size shows about 50% reduction in
runtime on my HSW and BSW boxes. Slightly less with more
reasonable LUT size but still easily measurable in tens
of microseconds.

Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver
to provide coherent graphics memory, meaning that the GPU sees any
content written to the coherent memory on the next GPU operation that
touches that memory, and the CPU sees any content written by the GPU
to that memory immediately after any fence object trailing the GPU
operation is signaled.
Paravirtual drivers that otherwise require explicit synchronization
needs to do this by hooking up dirty tracking to pagefault handlers
and buffer object validation.
Provide mm helpers needed for this and that also allow for huge pmd-
and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7).
The code has been tested and exercised by a tailored version of mesa
where we disable all explicit synchronization and assume graphics memory
is coherent. The performance loss varies of course; a typical number is
around 5%.

- Clean up of the default PCM mmap handling for vmalloc & SG-buffer
- Fix potential races at ALSA timer open
- A few new PCM API extensions; just preliminary core changes, the

- Continued ASoC componentization works; now almost everything is a
common ASoC component object. A lot of refactoring and

- Wake on voice support for Chromebooks
- SPI support and trigger word detection for RT5677
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems

- Plumbing the legacy HD-audio driver with Intel SOF HDMI
- DP-MST support for Nvidia HDMI codecs
- Realtek quirks cleanups and new additions as usual

The ATI Rage 128 driver has been the only user of ATI PCI GART code
since Radeon dropped UMS support in commit 8333f607a6 ("drm/radeon:
remove UMS support"). Clean up the drm top level directory, Kconfig and
Makefile by making ati_pcigart.[ch] part of r128. Drop the
CONFIG_DRM_ATI_PCIGART config option made redundant by the change.
This reduces drm.ko module size slightly when legacy drivers are
enabled, and moves the baggage to r128.ko instead.

compiled as modules or into the main drm builtin. However, if we want to

drm_self_refresh_helper_update_avg_times() was incorrectly accessing the
new incoming state after drm_atomic_helper_commit_hw_done(). But this
state might have already been superceeded by an !nonblock atomic update
resulting in dereferencing an already free'd crtc_state.
TODO I *think* this will more or less do the right thing.. althought I'm
not 100% sure if, for example, we enter psr in a nonblock commit, and
then leave psr in a !nonblock commit that overtakes the completion of
the nonblock commit. Not sure if this sort of scenario can happen in
practice. But not crashing is better than crashing, so I guess we
should either take this patch or rever the self-refresh helpers until
Sean can figure out a better solution.

messages may be transmitted during resume and thus allow
suspend/resume reprobing for DP MST to work
* nouveau: Avoid grabbing runtime PM references when handling short DP
pulses, so that handling sideband messages in resume codepaths with the

Commit c40069cb7b ("drm: add mmap() to drm_gem_object_funcs")
introduced a GEM object mmap() hook which is expected to subtract the
fake offset from vm_pgoff. However, for mmap() on dmabufs, there is not
a fake offset.
To fix this, let's always call mmap() object callback with an offset of 0,
and leave it up to drm_gem_mmap_obj() to remove the fake offset.
TTM still needs the fake offset, so we have to add it back until that's
fixed.

Allow codec driver register callback function for plug event.
The callback registration flow:
dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec
dw-hdmi-i2s-audio implements hook_plugged_cb op
so codec driver can register the callback.
dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device
can register the callback.
When connector plug/unplug event happens, report this event using the
callback.
Make sure that audio and drm are using the single source of truth for
connector status.

For very subtle mistakes with topology refs, it can be rather difficult
to trace them down with the debugging info that we already have. I had
one such issue recently while trying to implement suspend/resume
reprobing for MST, and ended up coming up with this.
Inspired by Chris Wilson's wakeref tracking for i915, this adds a very
similar feature to the DP MST helpers, which allows for partial tracking
of topology refs for both ports and branch devices. This is a lot less
advanced then wakeref tracking: we merely keep a count of all of the
spots where a topology ref has been grabbed or dropped, then dump out
that history in chronological order when a port or branch device's
topology refcount reaches 0. So far, I've found this incredibly useful
for debugging topology refcount errors.
Since this has the potential to be somewhat slow and loud, we add an
expert kernel config option to enable or disable this feature,
CONFIG_DRM_DEBUG_DP_MST_TOPOLOGY_REFS.
Changes since v1:
* Don't forget to destroy topology_ref_history_lock
Changes since v4:
* Correct order of kref_put()/topology_ref_history_unlock - we can't
unlock the history after kref_put() since the memory might have been
freed by that point
* Don't print message on allocation error failures, the kernel already
does this for us
Changes since v5:
* Get rid of some leftover usages of %px
* Remove a leftover empty return; statement

Finally! For a very long time, our MST helpers have had one very
annoying issue: They don't know how to reprobe the topology state when
coming out of suspend. This means that if a user has a machine connected
to an MST topology and decides to suspend their machine, we lose all
topology changes that happened during that period. That can be a big
problem if the machine was connected to a different topology on the same
port before resuming, as we won't bother reprobing any of the ports and
likely cause the user's monitors not to come back up as expected.
So, we start fixing this by teaching our MST helpers how to reprobe the
link addresses of each connected topology when resuming. As it turns
out, the behavior that we want here is identical to the behavior we want
when initially probing a newly connected MST topology, with a couple of
important differences:
- We need to be more careful about handling the potential races between
events from the MST hub that could change the topology state as we're
performing the link address reprobe
- We need to be more careful about handling unlikely state changes on
ports - such as an input port turning into an output port, something
that would be far more likely to happen in situations like the MST hub
we're connected to being changed while we're suspend
Both of which have been solved by previous commits. That leaves one
requirement:
- We need to prune any MST ports in our in-memory topology state that
were present when suspending, but have not appeared in the post-resume
link address response from their parent branch device
Which we can now handle in this commit by modifying
drm_dp_send_link_address(). We then introduce suspend/resume reprobing
by introducing drm_dp_mst_topology_mgr_invalidate_mstb(), which we call
in drm_dp_mst_topology_mgr_suspend() to traverse the in-memory topology
state to indicate that each mstb needs it's link address resent and PBN
resources reprobed.
On resume, we start back up &mgr->work and have it reprobe the topology
in the same way we would on a hotplug, removing any leftover ports that
no longer appear in the topology state.
Changes since v4:
* Split indenting changes in drm_dp_mst_topology_mgr_resume() into a
separate patch
* Only fire hotplugs when something has actually changed after a link
address probe
* Don't try to change port->connector at all on ports, just throw out
ports that need their connectors removed to make things easier.

This is a complicated one. Essentially, there's currently a problem in the MST
core that hasn't really caused any issues that we're aware of (emphasis on "that
we're aware of"): locking.
When we go through and probe the link addresses and path resources in a
topology, we hold no locks when updating ports with said information. The
members I'm referring to in particular are:
- ldps
- ddps
- mcs
- pdt
- dpcd_rev
- num_sdp_streams
- num_sdp_stream_sinks
- available_pbn
- input
- connector
Now that we're handling UP requests asynchronously and will be using some of
the struct members mentioned above in atomic modesetting in the future for
features such as PBN validation, this is going to become a lot more important.
As well, the next few commits that prepare us for and introduce suspend/resume
reprobing will also need clear locking in order to prevent from additional
racing hilarities that we never could have hit in the past.
So, let's solve this issue by using &mgr->base.lock, the modesetting
lock which currently only protects &mgr->base.state. This works
perfectly because it allows us to avoid blocking connection_mutex
unnecessarily, and we can grab this in connector detection paths since
it's a ww mutex. We start by having drm_dp_mst_handle_up_req() hold this
when updating ports. For drm_dp_mst_handle_link_address_port() things
are a bit more complicated. As I've learned the hard way, we can grab
&mgr->lock.base for everything except for port->connector. See, our
normal driver probing paths end up generating this rather obvious
lockdep chain:
&drm->mode_config.mutex
-> crtc_ww_class_mutex/crtc_ww_class_acquire
-> &connector->mutex
However, sysfs grabs &drm->mode_config.mutex in order to protect itself
from connector state changing under it. Because this entails grabbing
kn->count, e.g. the lock that the kernel provides for protecting sysfs
contexts, we end up grabbing kn->count followed by
&drm->mode_config.mutex. This ends up creating an extremely rude chain:
&kn->count
-> &drm->mode_config.mutex
-> crtc_ww_class_mutex/crtc_ww_class_acquire
-> &connector->mutex
I mean, look at that thing! It's just evil!!! This gross thing ends up
making any calls to drm_connector_register()/drm_connector_unregister()
impossible when holding any kind of modesetting lock. This is annoying
because ideally, we always want to ensure that
drm_dp_mst_port->connector never changes when doing an atomic commit or
check that would affect the atomic topology state so that it can
reliably and easily be used from future DRM DP MST helpers to assist
with tasks such as scanning through the current VCPI allocations and
adding connectors which need to have their allocations updated in
response to a bandwidth change or the like.
Being able to hold &mgr->base.lock throughout the entire link probe
process would have been _great_, since we could prevent userspace from
ever seeing any states in-between individual port changes and as a
result likely end up with a much faster probe and more consistent
results from said probes. But without some rework of how we handle
connector probing in sysfs it's not at all currently possible. In the
future, maybe we can try using the sysfs locks to protect updates to
connector probing state and fix this mess.
So for now, to protect everything other than port->connector under
&mgr->base.lock and ensure that we still have the guarantee that atomic
check/commit contexts will never see port->connector change we use a
silly trick. See: port->connector only needs to change in order to
ensure that input ports (see the MST spec) never have a ghost connector
associated with them. But, there's nothing stopping us from simply
throwing the entire port out and creating a new one in order to maintain
that requirement while still keeping port->connector consistent across
the lifetime of the port in atomic check/commit contexts. For all
intended purposes this works fine, as we validate ports in any contexts
we care about before using them and as such will end up reporting the
connector as disconnected until it's port's destruction finalizes. So,
we just do that in cases where we detect port->input has transitioned
from true->false. We don't need to worry about the other direction,
since a port without a connector isn't visible to userspace and as such
doesn't need to be protected by &mgr->base.lock until we finish
registering a connector for it.
For updating members of drm_dp_mst_port other than port->connector, we
simply grab &mgr->base.lock in drm_dp_mst_link_probe_work() for already
registered ports, update said members and drop the lock before
potentially registering a connector and probing the link address of it's
children.
Finally, we modify drm_dp_mst_detect_port() to take a modesetting lock
acquisition context in order to acquire &mgr->base.lock under
&connection_mutex and convert all it's users over to using the
.detect_ctx probe hooks.
With that, we finally have well defined locking.
Changes since v4:
* Get rid of port->mutex, stop using connection_mutex and just use our own
modesetting lock - mgr->base.lock. Also, add a probe_lock that comes
before this patch.
* Just throw out ports that get changed from an output to an input, and
replace them with new ports. This lets us ensure that modesetting
contexts never see port->connector go from having a connector to being
NULL.
* Write an extremely detailed explanation of what problems this is
trying to fix, since there's a _lot_ of context here and I honestly
forgot some of it myself a couple times.
* Don't grab mgr->lock when reading port->mstb in
drm_dp_mst_handle_link_address_port(). It's not needed.

Currently, MST lacks locking in a lot of places that really should have
some sort of locking. Hotplugging and link address code paths are some
of the offenders here, as there is actually nothing preventing us from
running a link address probe while at the same time handling a
connection status update request - something that's likely always been
possible but never seen in the wild because hotplugging has been broken
for ages now (with the exception of amdgpu, for reasons I don't think
are worth digging into very far).
Note: I'm going to start using the term "in-memory topology layout" here
to refer to drm_dp_mst_port->mstb and drm_dp_mst_branch->ports.
Locking in these places is a little tougher then it looks though.
Generally we protect anything having to do with the in-memory topology
layout under &mgr->lock. But this becomes nearly impossible to do from
the context of link address probes due to the fact that &mgr->lock is
usually grabbed under random various modesetting locks, meaning that
there's no way we can just invert the &mgr->lock order and keep it
locked throughout the whole process of updating the topology.
Luckily there are only two workers which can modify the in-memory
topology layout: drm_dp_mst_up_req_work() and
drm_dp_mst_link_probe_work(), meaning as long as we prevent these two
workers from traveling the topology layout in parallel with the intent
of updating it we don't need to worry about grabbing &mgr->lock in these
workers for reads. We only need to grab &mgr->lock in these workers for
writes, so that readers outside these two workers are still protected
from the topology layout changing beneath them.
So, add the new &mgr->probe_lock and use it in both
drm_dp_mst_link_probe_work() and drm_dp_mst_up_req_work(). Additionally,
add some more detailed explanations for how this locking is intended to
work to drm_dp_mst_port->mstb and drm_dp_mst_branch->ports.

Once upon a time, hotplugging devices on MST branches actually worked in
DRM. Now, it only works in amdgpu (likely because of how it's hotplug
handlers are implemented). On both i915 and nouveau, hotplug
notifications from MST branches are noticed - but trying to respond to
them causes messaging timeouts and causes the whole topology state to go
out of sync with reality, usually resulting in the user needing to
replug the entire topology in hopes that it actually fixes things.
The reason for this is because the way we currently handle UP requests
in MST is completely bogus. drm_dp_mst_handle_up_req() is called from
drm_dp_mst_hpd_irq(), which is usually called from the driver's hotplug
handler. Because we handle sending the hotplug event from this function,
we actually cause the driver's hotplug handler (and in turn, all
sideband transactions) to block on
drm_device->mode_config.connection_mutex. This makes it impossible to
send any sideband messages from the driver's connector probing
functions, resulting in the aforementioned sideband message timeout.
There's even more problems with this beyond breaking hotplugging on MST
branch devices. It also makes it almost impossible to protect
drm_dp_mst_port struct members under a lock because we then have to
worry about dealing with all of the lock dependency issues that ensue.
So, let's finally actually fix this issue by handling the processing of
up requests asyncronously. This way we can send sideband messages from
most contexts without having to deal with getting blocked if we hold
connection_mutex. This also fixes MST branch device hotplugging on i915,
finally!

Since we're going to be implementing suspend/resume reprobing very soon,
we need to make sure we are extra careful to ensure that our locking
actually protects the topology state where we expect it to. Turns out
this isn't the case with drm_dp_port_setup_pdt() and
drm_dp_port_teardown_pdt(), both of which change port->mstb without
grabbing &mgr->lock.
Additionally, since most callers of these functions are just using it to
teardown the port's previous PDT and setup a new one we can simplify
things a bit and combine drm_dp_port_setup_pdt() and
drm_dp_port_teardown_pdt() into a single function:
drm_dp_port_set_pdt(). This function also handles actually ensuring that
we grab the correct locks when we need to modify port->mstb.

When reprobing an MST topology during resume, we have to account for the
fact that while we were suspended it's possible that mstbs may have been
removed from any ports in the topology. Since iterating downwards in the
topology requires that we hold &mgr->lock, destroying MSTBs from this
context would result in attempting to lock &mgr->lock a second time and
deadlocking.
So, fix this by first moving destruction of MSTBs into
destroy_connector_work, then rename destroy_connector_work and friends
to reflect that they now destroy both ports and mstbs.
Note that even though this means that MSTBs will still be accessible for
a short period of time between their removal from the topology and
delayed destruction, we are still protected against referencing a MSTB
with a refcount of 0 since we use kref_get_unless_zero() in most places.

drm_gem_object_funcs->vm_ops alone can't handle everything which needs
to be done for mmap(), tweaking vm_flags for example. So add a new
mmap() callback to drm_gem_object_funcs where this code can go to.
Note that the vm_ops field is not used in case the mmap callback is
present, it is expected that the callback sets vma->vm_ops instead.
Also setting vm_flags and vm_page_prot is the job of the new callback.
so drivers have more control over these flags.
drm_gem_mmap_obj() will use the new callback for object specific mmap
setup. With this in place the need for driver-speific fops->mmap
callbacks goes away, drm_gem_mmap can be hooked instead.
drm_gem_prime_mmap() will use the new callback too to just mmap gem
objects directly instead of jumping though loops to make
drm_gem_object_lookup() and fops->mmap work.

Add support for configuring Dynamic Range and Mastering InfoFrame from
the hdr_output_metadata connector property.
This patch adds a use_drm_infoframe flag to dw_hdmi_plat_data that platform
drivers use to signal when Dynamic Range and Mastering infoframes is supported.
This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version,
and only GXL support DRM InfoFrame.
These changes were based on work done by Zheng Yang <zhengyang@rock-chips.com>
to support DRM InfoFrame on the Rockchip 4.4 BSP kernel at [1] and [2]

Currently the property docs don't specify whether it's okay for two planes to
have the same zpos value and what user-space should expect in this case.
The unspoken, legacy rule used in the past was to make user-space figure
out the zpos from object IDs. However some drivers break this rule,
that's why the ordering is documented as unspecified in case the zpos
property is missing. User-space should rely on the zpos property only.
There are some cases in which user-space might read identical zpos
values for different planes.
For instance, in case the property is mutable, user-space might set two
planes' zpos to the same value. This is necessary to support user-space
using the legacy DRM API where atomic commits are not possible:
user-space needs to update the planes' zpos one by one.
Because of this, user-space should handle multiple planes with the same
zpos.
While at it, remove the assumption that zpos is only for overlay planes.
Additionally, update the drm_plane_state.zpos docs to clarify that zpos
disambiguation via plane object IDs is a recommendation for drivers, not
something user-space can rely on. In other words, when user-space sets
the same zpos on two planes, drivers should rely on the plane object ID.
v2: clarify drm_plane_state.zpos docs (Daniel)
v3: zpos is for all planes (Marius, Daniel)
v4: completely reword the drm_plane_state.zpos docs to make it clear the
recommendation to use plane IDs is for drivers in case user-space uses
duplicate zpos values (Pekka)
v5: reword commit message (Pekka, James)
v6: remove mention of Arm GPUs having planes which can't overlap,
because this isn't uAPI yet (Daniel)

DP 1.3 specification introduces the Link Training-tunable PHY Repeater,
and DP 1.4* supplemented it with new features. In the 1.4a spec, it was
introduced some innovations to make handy to add support for systems
with Thunderbolt or other repeater devices.
It is important to highlight that DP specification had some updates from
1.3 through 1.4a. In particular, DP 1.4 defines Repeater_FEC_CAPABILITY
at the address 0xf0004, and DP 1.4a redefined the address 0xf0004 to
DP_MAX_LANE_COUNT_PHY_REPEATER.
Changes since V4:
- Update commit message
- Fix misleading comments related to the spec version
Changes since V3:
- Replace spaces by tabs
Changes since V2:
- Drop the kernel-doc comment
- Reorder LTTPR according to register offset
Changes since V1:

Pinning lots of small buffer objects, such as cursors or sprites, to video
memory can lead to fragmentation, which is a problem for devices with only
a small amount of memory. As a result, framebuffer images might not get
pinned, even though there's enough space available overall.
The flag DRM_GEM_VRAM_PL_FLAG_TOPDOWN marks buffer objects to be pinned at
the high end of video memory. This leaves contiguous space available at
the memory's low end.

Currently the self refresh idle timer is a const set by the crtc. This
is fine if the self refresh entry/exit times are well-known for all
panels used on that crtc. However panels and workloads can vary quite a
bit, and a timeout which works well for one doesn't work well for
another.
In the extreme, if the timeout is too short we could get in a situation
where the self refresh exits are taking so long we queue up a self refresh
entry before the exit commit is even finished.
This patch changes the idle timeout to a moving average of the entry
times + a moving average of exit times + the crtc constant.
This patch was tested on rockchip, with a kevin CrOS panel the idle
delay averages out to about ~235ms (35 entry + 100 exit + 100 const). On
the same board, the bob panel idle delay lands around ~340ms (90 entry
+ 150 exit + 100 const).
WRT the dedicated mutex in self_refresh_data, it would be nice if we
could rely on drm_crtc.mutex to protect the average times, but there are
a few reasons why a separate lock is a better choice:
- We can't rely on drm_crtc.mutex being held if we're doing a nonblocking
commit
- We can't grab drm_crtc.mutex since drm_modeset_lock() doesn't tell us
whether the lock was already held in the acquire context (it eats
-EALREADY), so we can't tell if we should drop it or not
- We don't need such a heavy-handed lock for what we're trying to do,
commit ordering doesn't matter, so a point-of-use lock will be less
contentious

The drm panel bridge creates a connector using a connector type
explicitly passed by the display controller or bridge driver that
instantiates the panel bridge. Now that drm_panel reports its connector
type, we can use it to avoid passing an explicit (and often incorrect)
connector type to drm_panel_bridge_add() and
devm_drm_panel_bridge_add().
Several drivers report incorrect or unknown connector types to
userspace. Reporting a different type may result in a breakage. For that
reason, rename (devm_)drm_panel_bridge_add() to
(devm_)drm_panel_bridge_add_typed(), and add new
(devm_)drm_panel_bridge_add() functions that use the panel connector
type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed
function, they will be converted one by one after testing.

not explain some of the missed vblank hilarity we've been seeing on

mostly). I think those all go through the vblank completion event,
which has unconditional barriers - it always takes the spinlock.
Therefore no cc stable.

Ville noticed that on 32bit we might be breaking up the load/stores,
now that the vblank counter has been switched over to be 64 bit. Fix
that up by switching to atomic64_t. This this happens so rarely in

We are about to add a drm_bridge_state that inherits from
drm_private_state which is defined in drm_atomic.h. Problem is,
drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,
leading to "drm_private_state has incomplete type" error.
Let's force all users of the drm_bridge API to explicitly include
drm_bridge.h.

Lockdep reports a circular locking dependency with pages_lock taken in
the shrinker callback. The deadlock can't actually happen with current
users at least as a BO will never be purgeable when pages_lock is held.
To be safe, let's use mutex_trylock() instead and bail if a BO is locked
already.

Instead of requiring all drivers to set the dev and funcs fields of
drm_panel manually after calling drm_panel_init(), pass the data as
arguments to the function. This simplifies the panel drivers, and will
help future refactoring when adding new arguments to drm_panel_init().
The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection to verify that no call to
drm_panel_init() with a single argument still exists.

No issues turned up so far, so continue to cleanup: Drop the res_id

Add support to the shmem GEM helpers for tracking madvise state and
purging pages. This is based on the msm implementation.
The BO provides a list_head, but the list management is handled outside
of the shmem helpers as there are different locking requirements.

This patch adds a DRM ENUM property to the selected connectors.
This property is used for mentioning the protected content's type
from userspace to kernel HDCP authentication.
Type of the stream is decided by the protected content providers.
Type 0 content can be rendered on any HDCP protected display wires.
But Type 1 content can be rendered only on HDCP2.2 protected paths.
So when a userspace sets this property to Type 1 and starts the HDCP
enable, kernel will honour it only if HDCP2.2 authentication is through
for type 1. Else HDCP enable will be failed.

Generic framebuffer emulation uses a shadow buffer for framebuffers with
dirty() function. If drivers want to use the shadow FB without such a

latter flag is fbdev-only.

DRM clients, such as the fbdev emulation, have their buffer objects
mapped by default. Mapping a buffer implicitly prevents its relocation.
Hence, the buffer may permanently consume video memory while it's
allocated. This is a problem for drivers of low-memory devices, such as
ast, mgag200 or older framebuffer hardware, which will then not have
enough memory to display other content (e.g., X11).
This patch introduces drm_client_buffer_vmap() and _vunmap(). Internal
DRM clients can use these functions to unmap and remap buffer objects
as needed.
There's no reference counting for vmap operations. Callers are expected
to either keep buffers mapped (as it is now), or call vmap and vunmap
in pairs around code that accesses the mapped memory.
v2:
* remove several duplicated NULL-pointer checks
v3:
* style and typo fixes

Add generic code which creates symbolic links in sysfs, pointing to ddc
interface used by a particular video output. For example:
ls -l /sys/class/drm/card0-HDMI-A-1/ddc
lrwxrwxrwx 1 root root 0 Jun 24 10:42 /sys/class/drm/card0-HDMI-A-1/ddc \
-> ../../../../soc/13880000.i2c/i2c-2
This makes it easy for user to associate a display with its ddc adapter
and use e.g. ddcutil to control the chosen monitor.
This patch adds an i2c_adapter pointer to struct drm_connector. Particular
drivers can then use it instead of using their own private instance. If a
connector contains a ddc, then create a symbolic link in sysfs.

All available downstream ports - physical and logical - are exposed for
each MST device. They are listed in /dev/, following the same naming
scheme as SST devices by appending an incremental ID.
Although all downstream ports are exposed, only some will work as
expected. Consider the following topology:
+---------+
| ASIC |
+---------+
Conn-0|
|
+----v----+
+----| MST HUB |----+
| +---------+ |
| |
|Port-1 Port-2|
+-----v-----+ +-----v-----+
| MST | | SST |
| Display | | Display |
+-----------+ +-----------+
|Port-1
x
MST Path | MST Device
----------+----------------------------------
sst:0 | MST Hub
mst:0-1 | MST Display
mst:0-1-1 | MST Display's disconnected DP out
mst:0-1-8 | MST Display's internal sink
mst:0-2 | SST Display
On certain MST displays, the upstream physical port will ACK DPCD reads.
However, reads on the local logical port to the internal sink will
*NAK*. i.e. reading mst:0-1 ACKs, but mst:0-1-8 NAKs.
There may also be duplicates. Some displays will return the same GUID
when reading DPCD from both mst:0-1 and mst:0-1-8.
There are some device-dependent behavior as well. The MST hub used
during testing will actually *ACK* read requests on a disconnected
physical port, whereas the MST displays will NAK.
In light of these discrepancies, it's simpler to expose all downstream
ports - both physical and logical - and let the user decide what to use.
v3 changes:
* Change WARN_ON_ONCE -> DRM_ERROR on dpcd read errors
* Docstring and cosmetic fixes
v2 changes:
Moved remote aux device (un)registration to new mst connector late
register and early unregister helpers. Drivers should call these from
their own mst connector function hooks.
This is to solve an issue during driver unload, where mst connector
devices are unregistered before the remote aux devices are. In a setup
where aux devices are created as children of connector devices, the aux
device would be removed too early, and uncleanly. Doing so in
early_unregister solves this issue, as that is called before connector
unregistration.

Split struct mipi_dbi into an interface part and a display pipeline part.
The interface part can be used by drivers that need to initialize the
controller, but that won't upload the framebuffer over this interface.
MIPI DBI supports 3 interface types:
- A. Motorola 6800 type parallel bus
- B. Intel 8080 type parallel bus
- C. SPI type with 3 options:
I've embedded the SPI type specifics in the mipi_dbi struct to avoid
adding unnecessary complexity. If more interface types will be supported
in the future, the type specifics might have to be split out.
Rename functions to match the new struct mipi_dbi_dev:
- drm_to_mipi_dbi() -> drm_to_mipi_dbi_dev().
- mipi_dbi_init*() -> mipi_dbi_dev_init*().

initialize the controller, but that won't upload the framebuffer over
this interface.
tinydrm uses the variable name 'mipi' but this is not a good name since
MIPI refers to a lot of standards. This patch changes the variable name
to 'dbidev' where it refers to the pipeline part of struct mipi_dbi.

- Remove drm_connector_helper_funcs.detect, it's always connected.

The MIPI DBI standard support more pixel formats than what this helper
supports. Add an init function that lets the driver use different
format(s). This avoids open coding mipi_dbi_init() in st7586.
st7586 sets preferred_depth but this is not necessary since it only
supports one format.

This is only used by mipi-dbi drivers so move it there.
The reason this isn't moved to the SPI subsystem is that it will in a
later patch pass a dummy rx buffer for SPI controllers that need this.
Low memory boards (64MB) can run into a problem allocating such a "large"
contiguous buffer on every transfer after a long up time.
This leaves a very specific use case, so we'll keep the function here.
mipi-dbi will first go through a refactoring though, before this will
be done.
Remove SPI todo entry now that we're done with the tinydrm.ko SPI code.

Prep work before moving the function to mipi-dbi.
tinydrm_spi_transfer() was made to support one class of drivers in
drivers/staging/fbtft that has not been converted to DRM yet, so strip
away the unused functionality:
- Start byte (header) is not used.
- No driver relies on the automatic 16-bit byte swapping on little endian
machines with SPI controllers only supporting 8 bits per word.
Other changes:
- No need to initialize ret
- No need for the WARN since mipi-dbi only uses 8 and 16 bpw.
- Use spi_message_init_with_transfers()

spi-bcm2835 can handle >64kB buffers now so there is no need to check
->max_dma_len. The tinydrm_spi_max_transfer_size() max_len argument is
not used by any callers, so not needed.
Then we have the spi_max module parameter. It was added because
staging/fbtft has support for it and there was a report that someone used
it to set a small buffer size to avoid popping on a USB soundcard on a
Raspberry Pi. In hindsight it shouldn't have been added, I should have
waited for it to become a problem first. I don't know it anyone is
actually using it, but since tinydrm_spi_transfer() is being moved to
mipi-dbi, I'm taking the opportunity to remove it. I'll add it back to
mipi-dbi if someone complains.
With that out of the way, spi_max_transfer_size() can be used instead.
The chosen 16kB buffer size for Type C Option 1 (9-bit) interface is
somewhat arbitrary, but a bigger buffer will have a miniscule impact on
transfer speed, so it's probably fine.

DRM clients, such as the fbdev emulation, have their buffer objects
mapped by default. Mapping a buffer implicitly prevents its relocation.
Hence, the buffer may permanently consume video memory while it's
allocated. This is a problem for drivers of low-memory devices, such as
ast, mgag200 or older framebuffer hardware, which will then not have
enough memory to display other content (e.g., X11).
This patch introduces drm_client_buffer_vmap() and _vunmap(). Internal
DRM clients can use these functions to unmap and remap buffer objects
as needed.
There's no reference counting for vmap operations. Callers are expected
to either keep buffers mapped (as it is now), or call vmap and vunmap
in pairs around code that accesses the mapped memory.

to give DSC branch decoders a chance to expose their maximum throughput

This completes Emil's series of removing DRM_UNLOCKED from modern
drivers. It's entirely cargo-culted since we ignore it on
non-DRIVER_LEGACY drivers since:
commit ea487835e8
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Mon Sep 28 21:42:40 2015 +0200
drm: Enforce unlocked ioctl operation for kms driver ioctls
Now justifying why we can do this for legacy drives too (and hence
close the source of all the bogus copypasting) is a bit more involved.
DRM_UNLOCKED was introduced in:
commit ed8b670409
Author: Arnd Bergmann <arnd@arndb.de>
Date: Wed Dec 16 22:17:09 2009 +0000
drm: convert drm_ioctl to unlocked_ioctl
As a immediate hack to keep i810 happy, which would have deadlocked
without this trickery. The old BKL is automatically dropped in
schedule(), and hence the i810 vs. mmap_sem deadlock didn't actually
cause a real deadlock. But with a mutex it would. The solution was to
annotate these as DRM_UNLOCKED and mark i810 unsafe on SMP machines.
This conversion caused a regression, because unlike the BKL a mutex
isn't dropped over schedule (that thing again), which caused a vblank
wait in one thread to block the entire desktop and all its apps. Back
then we did vblank scheduling by blocking in the client, awesome isn't
it. This was fixed quickly in (ok not so quickly, took 2 years):
commit 8f4ff2b06a
Author: Ilija Hadzic <ihadzic@research.bell-labs.com>
Date: Mon Oct 31 17:46:18 2011 -0400
drm: do not sleep on vblank while holding a mutex
All the other DRM_UNLOCKED annotations for all the core ioctls was
work to reach finer-grained locking for modern drivers. This took
years, and culminated in:
commit fdd5b877e9
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Sat Dec 10 22:52:54 2016 +0100
drm: Enforce BKL-less ioctls for modern drivers
DRM_UNLOCKED was never required by any legacy drivers, except for the
vblank_wait IOCTL. Therefore we will not regress these old drivers by
going back to where we've been in 2011. For all modern drivers nothing
will change.
To make this perfectly clear, also add a comment to DRM_UNLOCKED.
v2: Don't forget about drm_ioc32.c (Michel).

The idea is that gem_prime_export is deprecated in favor of
obj_funcs.export. That's much easier to do if both have matching

Yes this is a bit a big patch, but since it's essentially a complete
rewrite of all the prime docs I didn't see how to better split it up.
Changes:
- Consistently point to drm_gem_object_funcs as the preferred hooks,
where applicable.
- Document all the hooks in &drm_driver that lacked kerneldoc.
- Completely new overview section, which now also includes the cleaned
up lifetime/reference counting subchapter. I also mentioned the weak
references in there due to the lookup caches.
- Completely rewritten helper intro section, highlight the
import/export related functionality.
- Polish for all the functions and more cross references.
I also sprinkled a bunch of todos all over.
Most important: 0 code changes in here. The cleanup motivated by
reading and improving all this will follow later on.
v2: Actually update the prime helper docs. Plus add a few FIXMEs that
I won't address right away in subsequent cleanup patches.
v3:
- Split out the function moving. This patch is now exclusively
documentation changes.
- Typos and nits (Sam).
v4: Polish suggestions from Noralf.

Rotations and reflections setup are needed in some scenarios to initialise
properly the initial framebuffer. Some drivers already had a bunch of
quirks to deal with this, such as either a private kernel command line
parameter (omapdss) or on the device tree (various panels).
In order to accomodate this, let's create a video mode parameter to deal
with the rotation and reflexion.

The drm subsystem also uses the video= kernel parameter, and in the
documentation refers to the fbdev documentation for that parameter.
However, that documentation also says that instead of giving the mode using
its resolution we can also give a name. However, DRM doesn't handle that
case at the moment. Even though in most case it shouldn't make any
difference, it might be useful for analog modes, where different standards
might have the same resolution, but still have a few different parameters
that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

The drm_client_panel_rotation function has been used so far to set the
default rotation based on the panel orientation.
However, we can have more sources of information to make that decision,
starting with the command line that we will introduce later in this series.
Change the name to remove the panel mention.

With the vmwgfx dirty tracking, the default TTM fault handler is not
completely sufficient (vmwgfx need to modify the vma->vm_flags member,
and also needs to restrict the number of prefaults).
We also want to replicate the new ttm_bo_vm_reserve() functionality
So start turning the TTM vm code into helpers: ttm_bo_vm_fault_reserved()
and ttm_bo_vm_reserve(), and provide a default TTM fault handler for other

This patch adds a new drm helper library to help drivers implement
self refresh. Drivers choosing to use it will register crtcs and
will receive callbacks when it's time to enter or exit self refresh
mode.
In its current form, it has a timer which will trigger after a
driver-specified amount of inactivity. When the timer triggers, the
helpers will submit a new atomic commit to shut the refreshing pipe
off. On the next atomic commit, the drm core will revert the self
refresh state and bring everything back up to be actively driven.
From the driver's perspective, this works like a regular disable/enable
cycle. The driver need only check the 'self_refresh_active' state in
crtc_state. It should initiate self refresh mode on the panel and enter
an off or low-power state.

Everyone who implements connector_helper_funcs->atomic_check reaches
into the connector state to get the atomic state. Instead of continuing
this pattern, change the callback signature to just give atomic state
and let the driver determine what it does and does not need from it.
Eventually all atomic functions should do this, but that's just too much
busy work for me.

This patch adds atomic variants for all of
pre_enable/enable/disable/post_disable bridge functions. These will be
called from the appropriate atomic helper functions. If the bridge
driver doesn't implement the atomic version of the function, we will
fall back to the vanilla implementation.
Note that some drivers call drm_bridge_disable directly, and these cases
are not covered. It's up to the driver to decide whether to implement
both atomic_disable and disable, or if it's not necessary.

This patch adds atomic_enable and atomic_disable callbacks to the
encoder helpers. This will allow encoders to make informed decisions in
their start-up/shutdown based on the committed state.
Aside from the new hooks, this patch also introduces the new signature
for .atomic_* functions going forward. Instead of passing object state
(well, encoders don't have atomic state, but let's ignore that), we pass
the entire atomic state so the driver can inspect more than what's
happening locally.
This is particularly important for the upcoming self refresh helpers.

We've moved the override and firmware EDID (simply "override EDID" from
now on) handling to the low level drm_do_get_edid() function in order to
transparently use the override throughout the stack. The idea is that
you get the override EDID via the ->get_modes() hook.
Unfortunately, there are scenarios where the DDC probe in drm_get_edid()
called via ->get_modes() fails, although the preceding ->detect()
succeeds.
In the case reported by Paul Wise, the ->detect() hook,
intel_crt_detect(), relies on hotplug detect, bypassing the DDC. In the
case reported by Ilpo Järvinen, there is no ->detect() hook, which is
interpreted as connected. The subsequent DDC probe reached via
->get_modes() fails, and we don't even look at the override EDID,
resulting in no modes being added.
Because drm_get_edid() is used via ->detect() all over the place, we
can't trivially remove the DDC probe, as it leads to override EDID
effectively meaning connector forcing. The goal is that connector
forcing and override EDID remain orthogonal.
Generally, the underlying problem here is the conflation of ->detect()
and ->get_modes() via drm_get_edid(). The former should just detect, and
the latter should just get the modes, typically via reading the EDID. As
long as drm_get_edid() is used in ->detect(), it needs to retain the DDC
probe. Or such users need to have a separate DDC probe step first.
The EDID caching between ->detect() and ->get_modes() done by some
drivers is a further complication that prevents us from making
drm_do_get_edid() adapt to the two cases.
Work around the regression by falling back to a separate attempt at
getting the override EDID at drm_helper_probe_single_connector_modes()
level. With a working DDC and override EDID, it'll never be called; the
override EDID will come via ->get_modes(). There will still be a failing
DDC probe attempt in the cases that require the fallback.
v2:
- Call drm_connector_update_edid_property (Paul)
- Update commit message about EDID caching (Daniel)

On Rockchip rk3288-based Chromebooks when you do a suspend/resume
cycle:
1. You lose the ability to detect an HDMI device being plugged in.
2. If you're using the i2c bus built in to dw_hdmi then it stops
working.
Let's add a hook to the core dw-hdmi driver so that we can call it in
dw_hdmi-rockchip in the next commit.
NOTE: the exact set of steps I've done here in resume come from
looking at the normal dw_hdmi init sequence in upstream Linux plus the
sequence that we did in downstream Chrome OS 3.14. Testing show that
it seems to work, but if an extra step is needed or something here is
not needed we could improve it.
As part of this change we'll refactor the hardware init bits of
dw-hdmi to happen all in one function and all at the same time. Since
we need to init the interrupt mutes before we request the IRQ, this
means moving the hardware init earlier in the function, but there
should be no problems with that. Also as part of this we now
unconditionally init the "i2c" parts of dw-hdmi, but again that ought
to be fine.

All drivers add all their connectors so there's no need to keep around an
array of available connectors. Instead we just put the useable (not
writeback) connectors in a temporary array using
drm_client_for_each_connector_iter() everytime we probe the outputs.
Other places where it's necessary to look at the connectors, we just
iterate over them using the same iterator function.
Rename functions which signature is changed since they will be moved to
drm_client in a later patch.

struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so
use that directly instead and attach it as a modeset array onto
drm_client_dev. drm_fb_helper will use this array to store its modesets
which means it will always initialize a drm_client, but it will not
register the client (callbacks) unless it's the generic fbdev emulation.
Code will later be moved to drm_client, so add code there in a new file
drm_client_modeset.c with MIT license to match drm_fb_helper.c.
The modeset connector array size is hardcoded for the cloned case to avoid
having to pass in a value from the driver. A value of 8 is chosen to err
on the safe side. This means that the max connector argument for
drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore,
a todo entry for this is added.
In pan_display_atomic() restore_fbdev_mode_force() is used instead of
restore_fbdev_mode_atomic() because that one will later become internal
to drm_client_modeset.
Locking order:
1. drm_fb_helper->lock
2. drm_master_internal_acquire
3. drm_client_dev->modeset_mutex

In the case of a normal sync update, the preparation of framebuffers (be
it calling drm_atomic_helper_prepare_planes() or doing setups with
drm_framebuffer_get()) are performed in the new_state and the respective
cleanups are performed in the old_state.
In the case of async updates, the preparation is also done in the
new_state but the cleanups are done in the new_state (because updates
are performed in place, i.e. in the current state).
The current code blocks async udpates when the fb is changed, turning
async updates into sync updates, slowing down cursor updates and
introducing regressions in igt tests with errors of type:
"CRITICAL: completed 97 cursor updated in a period of 30 flips, we
expect to complete approximately 15360 updates, with the threshold set
at 7680"
Fb changes in async updates were prevented to avoid the following scenario:
- Async update, oldfb = NULL, newfb = fb1, prepare fb1, cleanup fb1
- Async update, oldfb = fb1, newfb = fb2, prepare fb2, cleanup fb2
- Non-async commit, oldfb = fb2, newfb = fb1, prepare fb1, cleanup fb2 (wrong)
Where we have a single call to prepare fb2 but double cleanup call to fb2.
To solve the above problems, instead of blocking async fb changes, we
place the old framebuffer in the new_state object, so when the code
performs cleanups in the new_state it will cleanup the old_fb and we
will have the following scenario instead:
- Async update, oldfb = NULL, newfb = fb1, prepare fb1, no cleanup
- Async update, oldfb = fb1, newfb = fb2, prepare fb2, cleanup fb1
- Non-async commit, oldfb = fb2, newfb = fb1, prepare fb1, cleanup fb2
Where calls to prepare/cleanup are balanced.

The push-to-system function forces a buffer out of video RAM. This decision
should rather be made by the memory manager. By replacing the function with
calls to the kunmap and unpin functions, the buffer's memory becomes available,
but the buffer remains in VRAM until it's evicted by a pin operation.
This patch replaces the remaining instances of drm_gem_vram_push_to_system()
in ast and mgag200, and removes the function from DRM.

We introduced new functions in the commit bf39607c16 ("drm/fourcc: Pass
the format_info pointer to drm_format_plane_width/height") based on
previous ones but with a slightly different prototype. However, the
documentation wasn't changed to reflect that change.

So far, the drm_format_plane_height/width functions were operating on the
format's fourcc and was doing a lookup to retrieve the drm_format_info
structure and return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent.
In order to be extra consistent, also rename that function to
drm_format_info_plane_cpp and to a static function in the header to match
the current policy. The parameters order have also be changed to match the
other functions prototype.

drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling
are basically a lookup in the drm_format_info table plus an access to the
hsub and vsub fields of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to these functions is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.
This is amplified by the fact that most of the time the callers will have
to retrieve both the vsub and hsub fields, meaning that they would perform
twice the lookup.

There's now a pointer to struct drm_vram_mm stored in struct drm_device.
DRM drivers that use VRAM MM should use this field to refer to their
instance of the data structure. Appropriate helpers are now provided as
well.
Adding struct drm_vram_mm to struct drm_device further avoids wrappers
and boilerplate code in drivers. This patch implements default functions
for callbacks in struct drm_driver and struct file_operations that use
the struct drm_vram_mm stored in struct drm_device. Drivers that need to
provide their own implementations can still do so.
The patch also adds documentation for the VRAM helper library in general.

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.
There are also some rcar-du patches which crossover with media tree
but all should be acked by Mauro.

(cherry picked from commit 96354b5ca4)
We already have __drm_atomic_helper_connector_reset() and
__drm_atomic_helper_plane_reset(), extend this to crtc as well.
This will allow us to set default values in the crtc_state, without
having to do it in each driver separately.
Of all drivers that need conversion, only nouveau is done in this
commit, because it wrote its own __drm_atomic_helper_crtc_reset(),
clashing with the drm core.

This will enable the following patch to consolidate most device ids into
i915_pciids.h.
While cross-referencing the ids listed in i915_drv.h, with the ones listed
in i915_pciids.h, and also the comments in the latter, a bug for bug
approach was used. This means two things:
1.
Some ids are only present in i915_drv.h - obviously this means those parts
would not have been probed at all so they were not added to i915_pciids.h
2.
Some part type comments in i915_pciids.h were in disagreement with

As writeback jobs contain a framebuffer, drivers may need to prepare and
cleanup them the same way they can prepare and cleanup framebuffers for
planes. Add two new optional connector helper operations,
.prepare_writeback_job() and .cleanup_writeback_job() to support this.
The job prepare operation is called from
drm_atomic_helper_prepare_planes() to avoid a new atomic commit helper
that would need to be called by all drivers not using
drm_atomic_helper_commit(). The job cleanup operation is called from the
existing drm_writeback_cleanup_job() function, invoked both when
destroying the job as part of a aborted commit, or when the job
completes.
The drm_writeback_job structure is extended with a priv field to let
drivers store per-job data, such as mappings related to the writeback
framebuffer.
For internal plumbing reasons the drm_writeback_job structure needs to
store a back-pointer to the drm_writeback_connector. To avoid pushing
too much writeback-specific knowledge to drm_atomic_uapi.c, create a
drm_writeback_set_fb() function, move the writeback job setup code
there, and set the connector backpointer. The prepare_signaling()
function doesn't need to allocate writeback jobs and can ignore
connectors without a job, as it is called after the writeback jobs are
allocated to store framebuffers, and a writeback fence with a
framebuffer is an invalid configuration that gets rejected by the commit
check.

The drm_writeback_queue_job() function takes ownership of the passed job
and requires the caller to manually set the connector state
writeback_job pointer to NULL. To simplify drivers and avoid errors
(such as the missing NULL set in the vc4 driver), pass the connector
state pointer to the function instead of the job pointer, and set the
writeback_job pointer to NULL internally.

The DRM_BUS_FLAG_PIXDATA_POSEDGE and DRM_BUS_FLAG_PIXDATA_NEGEDGE macros
and their DRM_BUS_FLAG_SYNC_* counterparts define on which pixel clock
edge data and sync signals are driven. They are however used in some
drivers to define on which pixel clock edge data and sync signals are
sampled, which should usually (but not always) be the opposite edge of
the driving edge. This creates confusion.
Create four new macros for both PIXDATA and SYNC that explicitly state
the driving and sampling edge in their name to remove the confusion. The
driving macros are defined as the opposite of the sampling macros to
made code simpler based on the assumption that the driving and sampling
edges are opposite.

Here is the big char/misc driver patch pull request for 5.1-rc1.
The largest thing by far is the new habanalabs driver for their AI
accelerator chip. For now it is in the drivers/misc directory but will
probably move to a new directory soon along with other drivers of this
type.
Other than that, just the usual set of individual driver updates and
fixes. There's an "odd" merge in here from the DRM tree that they asked
me to do as the MEI driver is starting to interact with the i915 driver,
and it needed some coordination. All of those patches have been
properly acked by the relevant subsystem maintainers.
All of these have been in linux-next with no reported issues, most for
quite some time.

drm: tweak header name

The DP 1.4 spec defines the SDP header and SDP contents for
a Picture Parameter Set (PPS) that must be sent in advance
of DSC transmission to define the encoding characteristics.
This was done in one struct, drm_dsc_pps_infoframe, which
conatined the SDP header and PPS. Because the PPS is
a property of DSC over any connector, not just DP, and because
drm drivers may have their own SDP structs they wish to use,
make the functions that initialise SDP and PPS headers take
the components they operate on, not drm_dsc_pps_infoframe,

Native 420 and 422 transfer modes are new in DSC1.2
In these modes, each two pixels of a slice are treated as one
pixel, so the slice width is half as large (round down) for
the purposes of calucating the groups per line and chunk size
in bytes
In native 422 mode, each pixel has four components, so the
mux component of a group is larger by one additional mux word
and one additional component
Now that there is native 422 support, the configuration option
previously called enable422 is renamed to simple_422 to avoid
confusion

Create a new connector property to program colorspace to sink
devices. Modern sink devices support more than 1 type of
colorspace like 601, 709, BT2020 etc. This helps to switch
based on content type which is to be displayed. The decision
lies with compositors as to in which scenarios, a particular
colorspace will be picked.
This will be helpful mostly to switch to higher gamut colorspaces
like BT2020 when the media content is encoded as BT2020. Thereby
giving a good visual experience to users.
The expectation from userspace is that it should parse the EDID
and get supported colorspaces. Use this property and switch to the
one supported. Sink supported colorspaces should be retrieved by
userspace from EDID and driver will not explicitly expose them.
Basically the expectation from userspace is:
- Set up CRTC DEGAMMA/CTM/GAMMA to convert to some sink
colorspace
- Set this new property to let the sink know what it
converted the CRTC output to.
v2: Addressed Maarten and Ville's review comments. Enhanced
the colorspace enum to incorporate both HDMI and DP supported
colorspaces. Also, added a default option for colorspace.
v3: Removed Adobe references from enum definitions as per
Ville, Hans Verkuil and Jonas Karlman suggestions. Changed
Default to an unset state where driver will assign the colorspace
is not chosen by user, suggested by Ville and Maarten. Addressed
other misc review comments from Maarten. Split the changes to
have separate colorspace property for DP and HDMI.
v4: Addressed Chris and Ville's review comments, and created a
common colorspace property for DP and HDMI, filtered the list
based on the colorspaces supported by the respective protocol
standard.
v5: Made the property creation helper accept enum list based on
platform capabilties as suggested by Shashank. Consolidated HDMI
and DP property creation in the common helper.
v6: Addressed Shashank's review comments.
v7: Added defines instead of enum in uapi as per Brian Starkey's
suggestion in order to go with string matching at userspace. Updated
the commit message to add more details as well kernel docs.
v8: Addressed Maarten's review comments.
v9: Removed macro defines from uapi as per Brian Starkey and Daniel
Stone's comments and moved to drm include file. Moved back to older
design with exposing all HDMI colorspaces to userspace since infoframe
capability is there even on legacy platforms, as per Ville's review
comments.
v10: Fixed sparse warnings, updated the RB from Maarten and Jani's ack.
v11: Addressed Ville's review comments. Updated the Macro naming and
added DCI-P3 colorspace as well, defined in CTA 861.G spec.
v12: Appended BT709 and SMPTE 170M with YCC information as per Ville's
review comment to be clear and not to be confused with RGB.
v13: Reorder the colorspace macros.
v14: Removed DP as of now, will be added later once full support is
enabled, as per Ville's suggestion. Added Ville's RB.

Many users of drm_gem_object embed a struct reservation_object into
their subclassed struct, so let's add one to struct drm_gem_object.
This will allow removing the reservation object from the subclasses
and removing the ->gem_prime_res_obj callback.
With the addition, add a drm_gem_reservation_object_wait() helper
function for drivers to use in wait ioctls.

drm/i915 is tracking all wakeref owners with a cookie in order to
identify leaks. To that end, each rpm acquisition ops->get_power is
assigned a cookie which should be passed to ops->put_power to signify
its release (and removal from the list of wakeref owners). As snd/hda is
already using a bool to track current status of display_power extending
that to an unsigned long to hold the boolean cookie is a trivial
extension, and will quell all doubt that snd/hda is the cause of the
device runtime pm leaks.
v2: Keep using the power abstraction for local wakeref tracking.

With the removal of drmP.h from drm_modeset_helper.h
the drmP.h are no longer included by any include files
in include/drm.
The drmP.h file is thus only included explicit
either in .c files or in local .h files.
This makes the process of deleting the drmP.h includes easier
as we have a more local dependency chain.
v2:
- moved updates of .c files in drm/ to a dedicated
patch. This allows the updates to the *.c files
to be committed without the removal part.
So this patch can wait if it causes build failures
due to pending changes

The DRM driver stack is designed to work with cache coherent devices
only, but permits an optimization to be enabled in some cases, where
for some buffers, both the CPU and the GPU use uncached mappings,
removing the need for DMA snooping and allocation in the CPU caches.
The use of uncached GPU mappings relies on the correct implementation
of the PCIe NoSnoop TLP attribute by the platform, otherwise the GPU
will use cached mappings nonetheless. On x86 platforms, this does not
seem to matter, as uncached CPU mappings will snoop the caches in any
case. However, on ARM and arm64, enabling this optimization on a
platform where NoSnoop is ignored results in loss of coherency, which
breaks correct operation of the device. Since we have no way of
detecting whether NoSnoop works or not, just disable this
optimization entirely for ARM and arm64.

Since
commit 39b50c6038 ("drm/atomic_helper: Stop modesets on unregistered
connectors harder")
We've been failing atomic checks if they try to enable new displays on
unregistered connectors. This is fine except for the one situation that
breaks atomic assumptions: suspend/resume. If a connector is
unregistered before we attempt to restore the atomic state, something we
end up failing the atomic check that happens when trying to restore the
state during resume.
Normally this would be OK: we try our best to make sure that the atomic
state pre-suspend can be restored post-suspend, but failures at that
point usually don't cause problems. That is of course, until we
introduced the new atomic MST VCPI helpers:

[drm:drm_dp_atomic_release_vcpi_slots [drm_kms_helper]] *ERROR* no VCPI for [MST PORT:00000000f9e2b143] found in mst state 000000009fd2899a
This appears to be happening because we destroy the VCPI allocations
when disabling all connected displays while suspending, and those VCPI
allocations don't get restored on resume due to failing to restore the
atomic state.
So, fix this by introducing the suspending option to
drm_atomic_helper_duplicate_state() and use that to indicate in the
atomic state that it's being used for suspending or resuming the system,
and thus needs to be fixed up by the driver. We can then use the new
state->duplicated hook to tell update_connector_routing() in
drm_atomic_check_modeset() to allow for modesets on unregistered
connectors, which allows us to restore atomic states that contain MST
topologies that were removed after the state was duplicated and thus:
mostly fixing suspend and resume. This just leaves some issues that were
introduced with nouveau, that will be addressed next.
Changes since v3:
* Remove ->duplicated hunks that I left in the VCPI helpers by accident.
These don't need to be here, that was the supposed to be the purpose
of the last revision
Changes since v2:
* Remove the changes in this patch to the VCPI helpers, they aren't
needed anymore
Changes since v1:
* Rename suspend_or_resume to duplicated

This is only used by drm_irq_install(), which is an optional helper.
For legacy pci devices this is required (due to interrupt sharing without
msi/msi-x), and just making this the default exactly matches the behaviour
of all existing drivers using the drm_irq_install() helpers. In case that
ever becomes wrong drivers can roll their own irq handling, as many
drivers already do (for other reasons like needing a threaded interrupt
handler, or having an entire pile of different interrupt sources).

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

Some hardware may place additional restrictions on the gamma/degamma
curves described by our LUT properties. E.g., that a gamma curve never
decreases or that the red/green/blue channels of a LUT's entries must be
equal. Let's add a helper function that drivers can use to test that a
userspace-provided LUT is valid and doesn't violate hardware
requirements.
v2:
- Combine into a single helper that just takes a bitmask of the tests
to apply. (Brian Starkey)
- Add additional check (always performed) that LUT property blob size
is always a multiple of the LUT entry size. (stolen from ARM driver)
v3:
- Drop the LUT size check again since
drm_atomic_replace_property_blob_from_id() already covers this for
us. (Alexandru Gheorghe)
v4:
- Use an enum to describe possible test values rather than #define's;
this is cleaner to provide kerneldoc for. (Daniel Vetter)
- s/DRM_COLOR_LUT_INCREASING/DRM_COLOR_LUT_NON_DECREASING/. (Ville)

It is often useful to check whether the DRM format info retrieved from
the DRM framebuffer matches a specific YUV planes disposition.
This introduces helpers to quickly check that a provided format info
matches a YUV format with a specific disposition, in commonly-used
terminology.
The intent of providing helpers taking the format info instead of the
fourcc alone is to avoid the overhead of iterating through all formats
when the whole format info structure is available. As a result, these
helpers are very simple so they are made inline.

head: 21376e2c3c
commit: e9eafcb589 [1/2] drm: move drm_can_sleep() to drm_util.h

^~~~~~~~
...
So we have a situation where we do not pull in <linux/types.h>
when building for alpha and for ia64 we need even more definitions
are required.
Two invasive fixes where considered:
- Change all declarations of arch_irqs_disabled_flags() to use bool
- Add include of <linux/types.h> to all files that uses bool for
arch_irqs_disabled_flags
To invasive with a too high pain/benefit ratio, so dropped.
They would not cover ia64 either.
Some less invasive fixes was also considered:
- Add include of <linux/types.h> to drm_util.h
- Add include of <linux/interrupt.h> to drm_util.h
The first was dropped as this did not cover the ia64 case.
The latter was considered the best option as there could
be other similar cases and we would like the header files below
include/drm/ to be selfcontained.
So we end up pulling in a lot of stuff not needed, but this is
the price we pay in drm/ because the kernel headers are not all
selfcontained.
While at it, ordred the includefiles in drm_util in alphabetical order.
Build tested with alpha,ia64,arm,x86 with allmodconfig and allyesconfig.
v2:
- fix ia64 build, changed to include interrupt.h
- sort include files alphabetically

depending on whether the TV encoder is used or not. To
that end add a per-crtc max_vblank_count that takes
precedence over its device wide counterpart. The driver
can now call drm_crtc_set_max_vblank_count() to configure
the per-crtc value before calling drm_vblank_on().

There has been a TODO waiting for quite a long time in
drm_dp_mst_topology.c:
/* We cannot rely on port->vcpi.num_slots to update
* topology_state->avail_slots as the port may not exist if the parent
* branch device was unplugged. This should be fixed by tracking
* per-port slot allocation in drm_dp_mst_topology_state instead of
* depending on the caller to tell us how many slots to release.
*/
That's not the only reason we should fix this: forcing the driver to
track the VCPI allocations throughout a state's atomic check is
error prone, because it means that extra care has to be taken with the
order that drm_dp_atomic_find_vcpi_slots() and
drm_dp_atomic_release_vcpi_slots() are called in in order to ensure
idempotency. Currently the only driver actually using these helpers,
i915, doesn't even do this correctly: multiple ->best_encoder() checks
with i915's current implementation would not be idempotent and would
over-allocate VCPI slots, something I learned trying to implement
fallback retraining in MST.
So: simplify this whole mess, and teach drm_dp_atomic_find_vcpi_slots()
and drm_dp_atomic_release_vcpi_slots() to track the VCPI allocations for
each port. This allows us to ensure idempotency without having to rely
on the driver as much. Additionally: the driver doesn't need to do any
kind of VCPI slot tracking anymore if it doesn't need it for it's own
internal state.
Additionally; this adds a new drm_dp_mst_atomic_check() helper which
must be used by atomic drivers to perform validity checks for the new
VCPI allocations incurred by a state.
Also: update the documentation and make it more obvious that these
/must/ be called by /all/ atomic drivers supporting MST.
Changes since v9:
* Add some missing changes that were requested by danvet that I forgot
about after I redid all of the kref stuff:
* Remove unnecessary state changes in intel_dp_mst_atomic_check
* Cleanup atomic check logic for VCPI allocations - all we need to check in
compute_config is whether or not this state disables a CRTC, then free
VCPI based off that
Changes since v8:
* Fix compile errors, whoops!
Changes since v7:
- Don't check for mixed stale/valid VCPI allocations, just rely on
connector registration to stop such erroneous modesets
Changes since v6:
- Keep a kref to all of the ports we have allocations on. This required
a good bit of changing to when we call drm_dp_find_vcpi_slots(),
mainly that we need to ensure that we only redo VCPI allocations on
actual mode or CRTC changes, not crtc_state->active changes.
Additionally, we no longer take the registration of the DRM connector
for each port into account because so long as we have a kref to the
port in the new or previous atomic state, the connector will stay
registered.
- Use the small changes to drm_dp_put_port() to add even more error
checking to make misusage of the helpers more obvious. I added this
after having to chase down various use-after-free conditions that
started popping up from the new helpers so no one else has to
troubleshoot that.
- Move some accidental DRM_DEBUG_KMS() calls to DRM_DEBUG_ATOMIC()
- Update documentation again, note that find/release() should both not be
called on the same port in a single atomic check phase (but multiple
calls to one or the other is OK)
Changes since v4:
- Don't skip the atomic checks for VCPI allocations if no new VCPI
allocations happen in a state. This makes the next change I'm about
to list here a lot easier to implement.
- Don't ignore VCPI allocations on destroyed ports, instead ensure that
when ports are destroyed and still have VCPI allocations in the
topology state, the only state changes allowed are releasing said
ports' VCPI. This prevents a state with a mix of VCPI allocations
from destroyed ports, and allocations from valid ports.
Changes since v3:
- Don't release VCPI allocations in the topology state immediately in
drm_dp_atomic_release_vcpi_slots(), instead mark them as 0 and skip
over them in drm_dp_mst_duplicate_state(). This makes it so
drm_dp_atomic_release_vcpi_slots() is still idempotent while also
throwing warnings if the driver messes up it's book keeping and tries
to release VCPI slots on a port that doesn't have any pre-existing
VCPI allocation - danvet
- Change mst_state/state in some debugging messages to "mst state"
Changes since v2:
- Use kmemdup() for duplicating MST state - danvet
- Move port validation out of duplicate state callback - danvet
- Handle looping through MST topology states in
drm_dp_mst_atomic_check() so the driver doesn't have to do it
- Fix documentation in drm_dp_atomic_find_vcpi_slots()
- Move the atomic check for each individual topology state into it's
own function, reduces indenting
- Don't consider "stale" MST ports when calculating the bandwidth
requirements. This is needed because originally we relied on the
state duplication functions to prune any stale ports from the new
state, which would prevent us from incorrectly considering their
bandwidth requirements alongside legitimate new payloads.
- Add function references in drm_dp_atomic_release_vcpi_slots() - danvet
- Annotate atomic VCPI and atomic check functions with __must_check
- danvet
Changes since v1:
- Don't use the now-removed ->atomic_check() for private objects hook,
just give drivers a function to call themselves

The current way of handling refcounting in the DP MST helpers is really
confusing and probably just plain wrong because it's been hacked up many
times over the years without anyone actually going over the code and
seeing if things could be simplified.
To the best of my understanding, the current scheme works like this:
drm_dp_mst_port and drm_dp_mst_branch both have a single refcount. When
this refcount hits 0 for either of the two, they're removed from the
topology state, but not immediately freed. Both ports and branch devices
will reinitialize their kref once it's hit 0 before actually destroying
themselves. The intended purpose behind this is so that we can avoid
problems like not being able to free a remote payload that might still
be active, due to us having removed all of the port/branch device
structures in memory, as per:
commit 91a25e4631 ("drm/dp/mst: deallocate payload on port destruction")
Which may have worked, but then it caused use-after-free errors. Being
new to MST at the time, I tried fixing it;
commit 263efde31f ("drm/dp/mst: Get validated port ref in drm_dp_update_payload_part1()")
But, that was broken: both drm_dp_mst_port and drm_dp_mst_branch structs
are validated in almost every DP MST helper function. Simply put, this
means we go through the topology and try to see if the given
drm_dp_mst_branch or drm_dp_mst_port is still attached to something
before trying to use it in order to avoid dereferencing freed memory
(something that has happened a LOT in the past with this library).
Because of this it doesn't actually matter whether or not we keep keep
the ports and branches around in memory as that's not enough, because
any function that validates the branches and ports passed to it will
still reject them anyway since they're no longer in the topology
structure. So, use-after-free errors were fixed but payload deallocation
was completely broken.
Two years later, AMD informed me about this issue and I attempted to
come up with a temporary fix, pending a long-overdue cleanup of this
library:
commit c54c7374ff ("drm/dp_mst: Skip validating ports during destruction, just ref")
But then that introduced use-after-free errors, so I quickly reverted
it:
commit 9765635b30 ("Revert "drm/dp_mst: Skip validating ports during destruction, just ref"")
And in the process, learned that there is just no simple fix for this:
the design is just broken. Unfortunately, the usage of these helpers are
quite broken as well. Some drivers like i915 have been smart enough to
avoid accessing any kind of information from MST port structures, but
others like nouveau have assumed, understandably so, that
drm_dp_mst_port structures are normal and can just be accessed at any
time without worrying about use-after-free errors.
After a lot of discussion, me and Daniel Vetter came up with a better
idea to replace all of this.
To summarize, since this is documented far more indepth in the
documentation this patch introduces, we make it so that drm_dp_mst_port
and drm_dp_mst_branch structures have two different classes of
refcounts: topology_kref, and malloc_kref. topology_kref corresponds to
the lifetime of the given drm_dp_mst_port or drm_dp_mst_branch in it's
given topology. Once it hits zero, any associated connectors are removed
and the branch or port can no longer be validated. malloc_kref
corresponds to the lifetime of the memory allocation for the actual
structure, and will always be non-zero so long as the topology_kref is
non-zero. This gives us a way to allow callers to hold onto port and
branch device structures past their topology lifetime, and dramatically
simplifies the lifetimes of both structures. This also finally fixes the
port deallocation problem, properly.
Additionally: since this now means that we can keep ports and branch
devices allocated in memory for however long we need, we no longer need
a significant amount of the port validation that we currently do.
Additionally, there is one last scenario that this fixes, which couldn't
have been fixed properly beforehand:
- CPU1 unrefs port from topology (refcount 1->0)
- CPU2 refs port in topology(refcount 0->1)
Since we now can guarantee memory safety for ports and branches
as-needed, we also can make our main reference counting functions fix
this problem by using kref_get_unless_zero() internally so that topology
refcounts can only ever reach 0 once.

FB_DAMAGE_CLIPS is an optional plane property to mark damaged regions
on the plane in framebuffer coordinates of the framebuffer attached to
the plane.
The layout of blob data is simply an array of "struct drm_mode_rect".
Unlike plane src coordinates, damage clips are not in 16.16 fixed point.
As plane src in framebuffer cannot be negative so are damage clips. In
damage clip, x1/y1 are inclusive and x2/y2 are exclusive.
This patch also exports the kernel internal drm_rect to userspace as
drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient
to represent damage for current plane size.
Driver which are interested in enabling FB_DAMAGE_CLIPS property for a
plane should enable this property using drm_plane_enable_damage_clips.
v2:
- Input validation on damage clips against framebuffer size.
- Doc update, other minor changes.

I've also converted the obvious cases in drm core to use the helpers.
The only remaining instance of drm_modeset_lock_all_ctx() is in

deadlock. ATM, there's no way to inject code in the deadlock path with
the helpers, so it's unfit for conversion.

This patch introduces the 'vrr_enabled' CRTC property to allow
dynamic control over variable refresh rate support for a CRTC.
This property should be treated like a content hint to the driver -
if the hardware or driver is not capable of driving variable refresh
timings then this is not considered an error.
Capability for variable refresh rate support should be determined
by querying the vrr_capable drm connector property.
It is worth noting that while the property is intended for atomic use
it isn't filtered from legacy userspace queries. This allows for Xorg
userspace drivers to implement support.

Modern display hardware is capable of supporting variable refresh rates.
This patch introduces the "vrr_capable" property on the connector to
allow userspace to query support for variable refresh rates.
Atomic drivers should attach this property to connectors that are
capable of driving variable refresh rates using
drm_connector_attach_vrr_capable_property().
The value should be updated based on driver and hardware capability
by using drm_connector_set_vrr_capable_property().

This adds an optional function table on GEM objects.
The main benefit is for drivers that support more than one type of
memory (shmem,vram,cma) for their buffers depending on the hardware it
runs on. With the callbacks attached to the GEM object itself, it is
easier to have core helpers for the the various buffer types. The driver
only has to make the decision about buffer type on GEM object creation
and all other callbacks can be handled by the chosen helper.
drm_driver->gem_prime_res_obj has not been added since there's a todo to
put a reservation_object into drm_gem_object.

We do lockless access to these flags everywhere, and it's kinda not a
great idea to mix lockless and bitfields. Aside from that gcc isn't
generating great code for these.
If this ever becomes an issue size-wise, I think we need atomic_t here

This patch adds a new API to clean up the scheduler job resources. This
is primarliy needed in cases the job was created but was not queued to
the scheduler queue. Additionally with this change, the layer which
creates the scheduler job also gets to free up the job's resources and
this entails moving the dma_fence_put(finished_fence) to the drivers
ops free handler routines.

So far, struct ttm_bo_global_ref was the only way of initializing a struct

For some pixel formats .cpp structure in drm_format info it's not
enough to describe the peculiarities of the pixel layout, for example
tiled formats or packed formats at bit level.
What's implemented here is to add three new members to drm_format_info
that could describe such formats:
- char_per_block[3]
- block_w[3]
- block_h[3]
char_per_block will be put in a union alongside cpp, for transparent
compatibility with the existing format descriptions.
Regarding, block_w and block_h they are intended to be used through
their equivalent getters drm_format_info_block_width /
drm_format_info_block_height, the reason of the getters is to abstract
the fact that for normal formats block_w and block_h will be unset/0,
but the methods will be returning 1.
Additionally, convenience function drm_format_info_min_pitch had been
added that computes the minimum required pitch for a given pixel
format and buffer width.
Using that the following drm core functions had been updated to
generically handle both block and non-block formats:
- drm_fb_cma_get_gem_addr: for block formats it will just return the
beginning of the block.
- framebuffer_check: Use the newly added drm_format_info_min_pitch.
- drm_gem_fb_create_with_funcs: Use the newly added
drm_format_info_min_pitch.
- In places where is not expecting to handle block formats, like fbdev
helpers I just added some warnings in case the block width/height
are greater than 1.
Changes since v3:
- Add helper function for computing the minimum required pitch.
- Improve/cleanup documentation
Changes since v8:
- Fixed build on 32bits arm architectures, with:
- return DIV_ROUND_UP((u64)buffer_width * info->char_per_block[plane],
+ return DIV_ROUND_UP_ULL((u64)buffer_width * info->char_per_block[plane],

With the regular means of adding the dsi-component in probe it creates
a race condition with the panel probing, as the panel device only gets
created after the dsi-bus got created.
When the panel-driver is build as a module it currently fails hard as the
panel cannot be probed directly:
dw_mipi_dsi_bind()
__dw_mipi_dsi_probe()
creates dsi bus
creates panel device
triggers panel module load
panel not probed (module not loaded or panel probe slow)
drm_bridge_attach
fails with -EINVAL due to empty panel_bridge
Additionally the panel probing can run concurrently with dsi bringup
making it possible that the panel can already be found but dsi-attach
hasn't finished running.
To solve that cleanly we may want to only create the component after
the panel has finished probing, by calling component_add from the
host-attach dsi callback.
As that is specific to glue drivers, add a new struct for host_ops
so that glue drivers can tell the bridge to call specific functions
after the common host-attach and before the common host-detach run.

__dw_mipi_dsi_probe() does all the grabbing of resources and does it using
devm-helpers. So this is happening on each try of master bringup possibly
slowing down things a lot.
Drivers using the component framework may instead want to call
dw_mipi_dsi_probe separately in their probe function to setup resources
early. That way the dsi bus also gets created earlier and also not
recreated on each bind-try, so that attached panels can load their modules
and be probed way before the bridge-attach in the bind call.
So drop the call to __dw_mipi_dsi_probe and modify the function to take
a struct dw_mipi_dsi instead of the platform-device.

There's no reason to track the atomic state three times. Unfortunately,
this is currently what we're doing, and even worse is that there is only
one actually correct state pointer: the one in mst_state->base.state.
mgr->state never seems to be used, along with the one in
mst_state->state.
This confused me for over 4 hours until I realized there was no magic
behind these pointers. So, let's save everyone else from the trouble.

The DSI devices have a maximum operating frequency specified
in their data sheet per the MIPI specification, and DSI hosts
that can scale their frequency need this information to set
their clock dividers right.
As current panel drivers often lack this information, specify
that setting it to zero will make the DSI host use some
reasonable default.

Unfortunately, it appears our fix in:
commit b5d29843d8 ("drm/atomic_helper: Allow DPMS On<->Off changes
for unregistered connectors")
Which attempted to work around the problems introduced by:
commit 4d80273976 ("drm/atomic_helper: Disallow new modesets on
unregistered connectors")
Is still not the right solution, as modesets can still be triggered
outside of drm_atomic_set_crtc_for_connector().
So in order to fix this, while still being careful that we don't break
modesets that a driver may perform before being registered with
userspace, we replace connector->registered with a tristate member,
connector->registration_state. This allows us to keep track of whether
or not a connector is still initializing and hasn't been exposed to
userspace, is currently registered and exposed to userspace, or has been
legitimately removed from the system after having once been present.
Using this info, we can prevent userspace from performing new modesets
on unregistered connectors while still allowing the driver to perform
modesets on unregistered connectors before the driver has finished being
registered.
Changes since v1:
- Fix WARN_ON() in drm_connector_cleanup() that CI caught with this
patchset in igt@drv_module_reload@basic-reload-inject and
igt@drv_module_reload@basic-reload by checking if the connector is
registered instead of unregistered, as calling drm_connector_cleanup()
on a connector that hasn't been registered with userspace yet should
stay valid.
- Remove unregistered_connector_check(), and just go back to what we
were doing before in commit 4d80273976 ("drm/atomic_helper: Disallow
new modesets on unregistered connectors") except replacing
READ_ONCE(connector->registered) with drm_connector_is_unregistered().

This fixes a general protection fault, caused by accessing the contents
of a flip_done completion object that has already been freed. It occurs
due to the preemption of a non-blocking commit worker thread W by
another commit thread X. X continues to clear its atomic state at the
end, destroying the CRTC commit object that W still needs. Switching
back to W and accessing the commit objects then leads to bad results.
Worker W becomes preemptable when waiting for flip_done to complete. At
this point, a frequently occurring commit thread X can take over. Here's
an example where W is a worker thread that flips on both CRTCs, and X
does a legacy cursor update on both CRTCs:
...
1. W does flip work
2. W runs commit_hw_done()
3. W waits for flip_done on CRTC 1
4. > flip_done for CRTC 1 completes
5. W finishes waiting for CRTC 1
6. W waits for flip_done on CRTC 2
7. > Preempted by X
8. > flip_done for CRTC 2 completes
9. X atomic_check: hw_done and flip_done are complete on all CRTCs
10. X updates cursor on both CRTCs
11. X destroys atomic state
12. X done
13. > Switch back to W
14. W waits for flip_done on CRTC 2
15. W raises general protection fault
The error looks like so:
general protection fault: 0000 [#1] PREEMPT SMP PTI

Note that i915 has this issue masked, since hw_done is signaled after
waiting for flip_done. Doing so will block the cursor update from
happening until hw_done is signaled, preventing the cursor commit from
destroying the state.
v2: The reference on the commit object needs to be obtained before
hw_done() is signaled, since that's the point where another commit
is allowed to modify the state. Assuming that the
new_crtc_state->commit object still exists within flip_done() is
incorrect.
Fix by getting a reference in setup_commit(), and releasing it
during default_clear().

This patch is for VK_KHR_timeline_semaphore extension, semaphore is called syncobj in kernel side:
This extension introduces a new type of syncobj that has an integer payload
identifying a point in a timeline. Such timeline syncobjs support the
following operations:
* CPU query - A host operation that allows querying the payload of the
timeline syncobj.
* CPU wait - A host operation that allows a blocking wait for a
timeline syncobj to reach a specified value.
* Device wait - A device operation that allows waiting for a
timeline syncobj to reach a specified value.
* Device signal - A device operation that allows advancing the
timeline syncobj to a specified value.
v1:
Since it's a timeline, that means the front time point(PT) always is signaled before the late PT.
a. signal PT design:
Signal PT fence N depends on PT[N-1] fence and signal opertion fence, when PT[N] fence is signaled,
the timeline will increase to value of PT[N].
b. wait PT design:
Wait PT fence is signaled by reaching timeline point value, when timeline is increasing, will compare
wait PTs value with new timeline value, if PT value is lower than timeline value, then wait PT will be
signaled, otherwise keep in list. syncobj wait operation can wait on any point of timeline,
so need a RB tree to order them. And wait PT could ahead of signal PT, we need a sumission fence to
perform that.
v2:
1. remove unused DRM_SYNCOBJ_CREATE_TYPE_NORMAL. (Christian)
2. move unexposed denitions to .c file. (Daniel Vetter)
3. split up the change to drm_syncobj_find_fence() in a separate patch. (Christian)
4. split up the change to drm_syncobj_replace_fence() in a separate patch.
5. drop the submission_fence implementation and instead use wait_event() for that. (Christian)
6. WARN_ON(point != 0) for NORMAL type syncobj case. (Daniel Vetter)
v3:
1. replace normal syncobj with timeline implemenation. (Vetter and Christian)
a. normal syncobj signal op will create a signal PT to tail of signal pt list.
b. normal syncobj wait op will create a wait pt with last signal point, and this wait PT is only signaled by related signal point PT.
2. many bug fix and clean up
3. stub fence moving is moved to other patch.
v4：
1. fix RB tree loop with while(node=rb_first(...)). (Christian)
2. fix syncobj lifecycle. (Christian)
3. only enable_signaling when there is wait_pt. (Christian)
4. fix timeline path issues.
5. write a timeline test in libdrm
v5: (Christian)
1. semaphore is called syncobj in kernel side.
2. don't need 'timeline' characters in some function name.
3. keep syncobj cb.
v6: (Christian)
1. merge syncobj_timeline to syncobj structure.
2. simplify some check sentences.
3. some misc change.
4. fix CTS failed issue.
v7: (Christian)
1. error handling when creating signal pt.
2. remove timeline naming in func.
3. export flags in find_fence.
4. allow reset timeline.
v8:
1. use wait_event_interruptible without timeout
2. rename _TYPE_INDIVIDUAL to _TYPE_BINARY
v9:
1. rename signal_pt->base to signal_pt->fence_array to avoid misleading
2. improve kerneldoc
individual syncobj is tested by ./deqp-vk -n dEQP-VK*semaphore*
timeline syncobj is tested by ./amdgpu_test -s 9

With armada the last bigger driver that realistically needed these to
convert from legacy kms to atomic is converted. These helpers have
been broken more often than not the past 2 years, and as this little
patch series shows, tricked a bunch of people into using the wrong
helpers for their functions.
Aside: I think a lot more drivers should be using the device-level
drm_atomic_helper_shutdown/suspend/resume helpers and related
functions. In almost all the cases they get things exactly right.

In some IP implementations the reading of the phy-type may be broken.
One example are the Rockchip rk3228 and rk3328 socs that use a separate
vendor-type phy from Innosilicon but still report the HDMI20_TX type.
So allow the glue driver to force the vendor-phy for these cases.
In the future it may be necessary to allow forcing other types, but
for now we'll keep it simply to the case actually seen in the wild.

This reverts commit 0c08754b59.
commit 0c08754b59
("drm/panel: Add device_link from panel device to DRM device")
creates a circular dependency under these circumstances:
1. The panel depends on dsi-host because it is MIPI-DSI child
device.
2. dsi-host depends on the drm parent device (connector->dev->dev)
this should be allowed.
3. drm parent dev (connector->dev->dev) depends on the panel
after this patch.
This makes the dependency circular and while it appears it
does not affect any in-tree drivers (they do not seem to have
dsi hosts depending on the same parent device) this does not
seem right.
As noted in a response from Andrzej Hajda, the intent is
likely to make the panel dependent on the DRM device
(connector->dev) not its parent. But we have no way of
doing that since the DRM device doesn't contain any
struct device on its own (arguably it should).
Revert this until a proper approach is figured out.

Turns out we need the pixel format fixup not only for the addfb ioctl,
but also for fbdev emulation code.
Ideally we would place it in drm_mode_legacy_fb_format(). That would
create alot of churn though, and most drivers don't care because they
never ever run on a big endian platform. So add a new
drm_driver_legacy_fb_format() function instead which looks at the
mode_config->quirk_addfb_prefer_host_byte_order flag.

We wish to control certain driver_features flags on a per-device basis
while still sharing a single drm_driver instance across all the
devices. To that end introduce device.driver_features. By default
it will be set to ~0 to not impose any limits beyond
driver.driver_features. Drivers can then clear specific flags
in the per-device bitmask to limit the capabilities of the device.
An alternative approach would be to copy the driver_features from
the driver into the device in drm_dev_init(), however that would
require verifying that no driver is currently changing
driver.driver_features after drm_dev_init(). Hence the ~0 apporach
was easier.
Ideally we'd also make drm_driver const but there is plenty of code
left that wants to mutate it (eg. various vfunc assignments). We'll
need to fix all that up before we can make it const.
And while at it fix up the type of the feature flag passed to
drm_core_check_feature().

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.

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.

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.

duplicate the code for initializing the properties to their default

A lot of drivers duplicate the function to check if a format is yuv or not.
If we add a field (to denote whether the format is yuv or not) in the
drm_format_info table, all the drivers can use this field and it will
prevent duplication of similar logic.

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.
v1->v2: Fix missing NULL check in master_bind/unbind
Signed-off-by: Takashi Iwai <tiwai@suse.de>
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.

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.

If the user has created a read-only object, they should not be allowed
to circumvent the write protection by using a GGTT mmapping. Deny it.
Also most machines do not support read-only GGTT PTEs, so again we have
to reject attempted writes. Fortunately, this is known a priori, so we
can at least reject in the call to create the mmap (with a sanity check
in the fault handler).

I also briefly looked at implementing an u64 version of the PCI config
read functions, but I concluded this wouldn't be trivial, so it's not

while reading the register in two separate operations.

- Remove the i915.ko bits so this can be easily backported in order

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.

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.

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().

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.

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.

The meaning of the mode_config max_width/height fields has not been
entirely clear. They are used both as the max framebuffer dimensions,
and they are also used by drm_mode_getconnector() to filter out
any mode whose hdisplay/vdisplay exceed those limits.
Let's put it in writing that max_width/height only refrer to the max
framebuffer dimensions, and should those be higher than the hardware
limits for display timings the driver must validate the latter using
some other means.
We'll keep the max_width/height usage in drm_mode_getconnector()
because setcrtc treats hdisplay/vdisplay also as the primary plane
width, and having a plane bigger than the max fb size doesn't make
much sense (if we ignore scaling that is). It all works out fine
as long as the max fb dimensions are at least equal to the max
timing limits. If the opposite were true we may want to rethink
what drm_mode_getconnector() does. Maybe do the mode filtering
only for non-atomic userspace?

Add the WRITEBACK_OUT_FENCE_PTR property to writeback connectors, to
enable userspace to get a fence which will signal once the writeback is

Writeback connectors represent writeback engines which can write the
CRTC output to a memory framebuffer. Add a writeback connector type and
related support functions.
Drivers should initialize a writeback connector with
drm_writeback_connector_init() which takes care of setting up all the
writeback-specific details on top of the normal functionality of
drm_connector_init().
Writeback connectors have a WRITEBACK_FB_ID property, used to set the
output framebuffer, and a WRITEBACK_PIXEL_FORMATS blob used to expose the
supported writeback formats to userspace.
When a framebuffer is attached to a writeback connector with the
WRITEBACK_FB_ID property, it is used only once (for the commit in which
it was included), and userspace can never read back the value of
WRITEBACK_FB_ID. WRITEBACK_FB_ID can only be set if the connector is
attached to a CRTC.
Changes since v1:
- Added drm_writeback.c + documentation
- Added helper to initialize writeback connector in one go
- Added core checks
- Squashed into a single commit
- Dropped the client cap
- Writeback framebuffers are no longer persistent
Changes since v2:
Daniel Vetter:
- Subclass drm_connector to drm_writeback_connector
- Relax check to allow CRTC to be set without an FB
- Add some writeback_ prefixes
- Drop PIXEL_FORMATS_SIZE property, as it was unnecessary
Gustavo Padovan:
- Add drm_writeback_job to handle writeback signalling centrally
Changes since v3:
- Rebased
- Rename PIXEL_FORMATS -> WRITEBACK_PIXEL_FORMATS
Chances since v4:
- Embed a drm_encoder inside the drm_writeback_connector to
reduce the amount of boilerplate code required from the drivers
that are using it.
Changes since v5:
- Added Rob Clark's atomic_commit() vfunc to connector helper
funcs, so that writeback jobs are committed from atomic helpers
- Updated create_writeback_properties() signature to return an
error code rather than a boolean false for failure.
- Free writeback job with the connector state rather than when
doing the cleanup_work()
Changes since v7:
- fix extraneous use of out_fence that is only introduced in a
subsequent patch.
Changes since v8:
- whitespace changes pull from subsequent patch
Changes since v9:
- Revert the v6 changes that free the writeback job in the connector
state cleanup and return to doing it in the cleanup_work() function

Searching for an available hole by address is slow, as there no
guarantee that a hole will be available and so we must walk over all
nodes in the rbtree before we determine the search was futile. In many
cases, the caller doesn't strictly care for the highest available hole
and was just opportunistically laying out the address space in a
preferred order. In such cases, the caller can accept any address and
would rather do so then do a slow walk.
To be able to mix search strategies, the caller wants to tell the drm_mm
how long to spend on the search. Without a good guide for what should be
the best split, start with a request to try once at most. That is return
the top-most (or lowest) hole if it fulfils the alignment and size
requirements.

As we keep an rbtree of available holes sorted by their size, we can
very easily determine if there is any hole large enough that might
satisfy the allocation request. This helps when dealing with a highly
fragmented address space and a request for a search by address.
To cache the largest size, we convert into the cached rbtree variant
which tracks the leftmost node for us. However, currently we sorted into
ascending size order so the leftmost node is the smallest, and so to
make it the largest hole we need to invert our sorting.

Add device_link from panel device (supplier) to DRM device (consumer)
when drm_panel_attach() is called. This patch should protect the master
DRM driver if an attached panel driver unbinds while it is in use. The
device_link should make sure the DRM device is unbound before the panel
driver becomes unavailable.
The device_link is removed when drm_panel_detach() is called. The
drm_panel_detach() should be called by the consumer DRM driver, not the
panel driver, otherwise both drivers are racing to delete the same link.

Added content_type property to drm_connector_state
in order to properly handle external HDMI TV content-type setting.
v2:
* Moved helper function which attaches content type property
to the drm core, as was suggested.
Removed redundant connector state initialization.
v3:
* Removed caps in drm_content_type_enum_list.
After some discussion it turned out that HDMI Spec 1.4
was wrongly assuming that IT Content(itc) bit doesn't affect
Content type states, however itc bit needs to be manupulated
as well. In order to not expose additional property for itc,
for sake of simplicity it was decided to bind those together
in same "content type" property.
v4:
* Added it_content checking in intel_digital_connector_atomic_check.
Fixed documentation for new content type enum.
v5:
* Moved patch revision's description to commit messages.
v6:
* Minor naming fix for the content type enumeration string.
v7:
* Fix parameter name for documentation and parameter alignment
in order not to get warning. Added Content Type description to
new HDMI connector properties section.
v8:
* Thrown away unneeded numbers from HDMI content-type property
description. Switch to strings desription instead of plain
definitions.
v9:
* Moved away hdmi specific content-type enum from
drm_connector_state. Content type property should probably not
be bound to any specific connector interface in
drm_connector_state.
Same probably should be done to hdmi_picture_aspect_ration enum
which is also contained in drm_connector_state. Added special
helper function to get derive hdmi specific relevant infoframe
fields.
v10:
* Added usage description to HDMI properties kernel doc.
v11:
* Created centralized function for filling HDMI AVI infoframe, based

issue:
there are VMC page fault occurred if force APP kill during
3dmark test, the cause is in entity_fini we manually signal
all those jobs in entity's queue which confuse the sync/dep
mechanism:
1)page fault occurred in sdma's clear job which operate on
shadow buffer, and shadow buffer's Gart table is cleaned by
ttm_bo_release since the fence in its reservation was fake signaled
by entity_fini() under the case of SIGKILL received.
2)page fault occurred in gfx' job because during the lifetime
of gfx job we manually fake signal all jobs from its entity
in entity_fini(), thus the unmapping/clear PTE job depend on those
result fence is satisfied and sdma start clearing the PTE and lead
to GFX page fault.
fix:
1)should at least wait all jobs already scheduled complete in entity_fini()
if SIGKILL is the case.
2)if a fence signaled and try to clear some entity's dependency, should
set this entity guilty to prevent its job really run since the dependency
is fake signaled.
v2:
splitting drm_sched_entity_fini() into two functions:
1)The first one is does the waiting, removes the entity from the
runqueue and returns an error when the process was killed.
2)The second one then goes over the entity, install it as
completion signal for the remaining jobs and signals all jobs
with an error code.
v3:
1)Replace the fini1 and fini2 with better name
2)Call the first part before the VM teardown in
amdgpu_driver_postclose_kms() and the second part
after the VM teardown
3)Keep the original function drm_sched_entity_fini to
refine the code.
v4:
1)Rename entity->finished to entity->last_scheduled;
2)Rename drm_sched_entity_fini_job_cb() to
drm_sched_entity_kill_jobs_cb();
3)Pass NULL to drm_sched_entity_fini_job_cb() if -ENOENT;

We parse the EDID and add all the modes in the connector's modelist.
This adds CEA modes with aspect ratio information too, regardless of
whether user space requested this information or not.
This patch:
-prunes the modes with aspect-ratio information, from the
drm_mode_get_connector modelist supplied to the user, if the
user-space has not set the aspect ratio DRM client cap. However if
such a mode is unique in the list, it is kept in the list, with
aspect-ratio flags reset.
-prepares a list of exposed modes, which is used to find unique modes
if aspect-ratio is not allowed.
-adds a new list_head 'exposed_head' in drm_mode_display, to traverse
the list of exposed modes.

To enable aspect-ratio support in DRM, blindly exposing the aspect
ratio information along with mode, can break things in existing
non-atomic user-spaces which have no intention or support to use this
aspect ratio information.
To avoid this, a new drm client cap is required to enable a non-atomic
user-space to advertise if it supports modes with aspect-ratio. Based
on this cap value, the kernel will take a call on exposing the aspect
ratio info in modes or not.
This patch adds the client cap for aspect-ratio.
Since no atomic-userspaces blow up on receiving aspect-ratio
information, the client cap for aspect-ratio is always enabled
for atomic clients.

DP_TRAINING_AUX_RD_INTERVAL with DP 1.3 spec changed bit scheeme from 8
bits to 7 in DPCD 0x000e. The 8th bit is used to identify extended
receiver capabilities. For panels that use this new feature wait interval
would be increased by 512 ms, when spec is max 16 ms. This behavior is
described in table 2-158 of DP 1.4 spec address 0000eh.
With the introduction of DP 1.4 spec main link clock recovery was
standardized to 100 us regardless of TRAINING_AUX_RD_INTERVAL value.
To avoid breaking panels that are not spec compiant we now warn on

Instead of relying on a scale which may increase rounding errors,
clip src by doing: src * (dst - clip) / dst and rounding the result
away from 1, so the new coordinates get closer to 1. We won't need
to fix up with a magic macro afterwards, because our scaling factor
will never go to the other side of 1.
Changes since v1:
- Adjust dst immediately, else drm_rect_width/height on dst gives bogus
results.
Change since v2:
- Get rid of macros and use 64-bits math.

account, or at least don't call drm_atoimc_set_fence_for_plane().
Cc'ing relevant people, or at least some. Some drivers also look like
they don't disable implicit fencing (e.g. amdgpu) because the explicit
fences and implicit fences are handled by entirely independent code
paths.
I also wonder whether we shouldn't just make the recommended helpers
the default ones, since a lot of drivers don't bother to handle the
implicit fences at all it seems. The helpers won't blow up even for
non-GEM drivers or GEM drivers which don't fill out the gem bo

mipi_dbi_enable_flush() wants to call the fb->dirty() hook from the
bowels of the .atomic_enable() hook. That prevents us from taking the
plane mutex in fb->dirty() unless we also plumb down the acquire
context.
Instead it seems simpler to split the fb->dirty() into a tinydrm
specific lower level hook that can be called from
mipi_dbi_enable_flush() and from a generic higher level
tinydrm_fb_dirty() helper. As we don't have a tinydrm specific
vfuncs table we'll just stick it into tinydrm_device directly
for now.
v2: Deal with the fb->dirty() in tinydrm_display_pipe_update() as well (Noralf)

These macros are similar to the DRM_<LEVEL> with the addition
of a struct device * to the arguments.
Convert the single drm_dev_printk function into 2 separate functions.
drm_dev_printk with a KERN_<LEVEL> * for generic use and drm_dev_dbg
for conditional masked use.
Remove the __func__ argument and use __builtin_return_address(0) to be
similar to the DRM_<LEVEL> macros uses.
Convert the DRM_DEV_<LEVEL> macros to remove now unnecessary arguments
and use a consistent style.
These macros are rarely used in the generic gpu/drm code so the code
size does not change much for a defconfig, but when more drivers are
enabled, there is ~4k savings.
Many of these macros have no existing use at all.

Using a flexible array for the blob data was a mistake by me. It
forces all users of the blob data to cast blob->data to something
else. void* is clearly superior so let's go back to the original
scheme.
Not a clean revert as the code has moved.
