e2c4ed148c drm/omap: fix max fclk divider for omap36xx
The OMAP36xx and AM/DM37x TRMs say that the maximum divider for DSS fclk
(in CM_CLKSEL_DSS) is 32. Experimentation shows that this is not
correct, and using divider of 32 breaks DSS with a flood or underflows
and sync losts. Dividers up to 31 seem to work fine.

There is another patch to the DT files to limit the divider correctly,
but as the DSS driver also needs to know the maximum divider to be able
to iteratively find good rates, we also need to do the fix in the DSS
driver.

eb0192fed0 drm/i915: Fix g4x sprite scaling stride check with GTT remapping
I forgot to update the g4x sprite scaling stride check when GTT
remapping was introduced. The stride of the original framebuffer
is irrelevant when remapping is used and instead we want to check
the stride of the remapped view.

Also drop the duplicate width_bytes check. We already check that
a few lines earlier.

cffb4c3ea3 drm/i915/dp: Fix dsc bpp calculations, v5.
There was a integer wraparound when mode_clock became too high,
and we didn't correct for the FEC overhead factor when dividing,
with the calculations breaking at HBR3.

As a result our calculated bpp was way too high, and the link width
limitation never came into effect.

Print out the resulting bpp calcululations as a sanity check, just
in case we ever have to debug it later on again.

We also used the wrong factor for FEC. While bspec mentions 2.4%,
all the calculations use 1/0.972261, and the same ratio should be
applied to data M/N as well, so use it there when FEC is enabled.

This fixes the FIFO underrun we are seeing with FEC enabled.

Changes since v2:
- Handle fec_enable in intel_link_compute_m_n, so only data M/N is adjusted. (Ville)
- Fix initial hardware readout for FEC. (Ville)
Changes since v3:
- Remove bogus fec_to_mode_clock. (Ville)
Changes since v4:
- Use the correct register for icl. (Ville)
- Split hw readout to a separate patch.

fcde8c7eea drm/i915/selftests: Exercise potential false lite-restore
If execlists's lite-restore is based on the common GEM context tag
rather than the per-intel_context LRCA, then a context switch between
two intel_contexts on the same engine derived from the same GEM context
will perform a lite-restore instead of a full context switch. We can
exploit this by poisoning the ringbuffer of the first context and trying
to trick a simple RING_TAIL update (i.e. lite-restore)

v2: Also check what happens if preempt ce[0] with ce[1] (both instances
on the same engine from the same parent context) [Tvrtko]

f21e8b80b7 drm/i915/mg: Use tc_port instead of port parameter to MG registers

a4311745bb drm/i915/userptr: Never allow userptr into the mappable GGTT
Daniel Vetter uncovered a nasty cycle in using the mmu-notifiers to
invalidate userptr objects which also happen to be pulled into GGTT
mmaps. That is when we unbind the userptr object (on mmu invalidation),
we revoke all CPU mmaps, which may then recurse into mmu invalidation.

We looked for ways of breaking the cycle, but the revocation on
invalidation is required and cannot be avoided. The only solution we
could see was to not allow such GGTT bindings of userptr objects in the
first place. In practice, no one really wants to use a GGTT mmapping of
a CPU pointer...

Just before Daniel's explosive lockdep patches land in v5.4-rc1, we got
a genuine blip from CI:

f59769c52c drm/komeda: Workaround for broken FLIP_COMPLETE timestamps
When initially turning a crtc on, drm_reset_vblank_timestamp will
set the vblank timestamp to 0 for any driver that doesn't provide
a ->get_vblank_timestamp() hook.

Unfortunately, the FLIP_COMPLETE event depends on that timestamp,
and the only way to regenerate a valid one is to have vblank
interrupts enabled and have a valid in-ISR call to
drm_crtc_handle_vblank.

Additionally, if the user doesn't request vblanks but _does_ request
FLIP_COMPLETE events, we still don't have a good timestamp: it'll be the
same stamp as the last vblank one.

Work around the issue by always enabling vblanks when the CRTC is on.
Reducing the amount of time that PL0 has to be unmasked would be nice to
fix at a later time.

Changes since v1 [https://patchwork.freedesktop.org/patch/331727/]:
 - moved drm_crtc_vblank_put call to the ->atomic_disable() hook

99785b86ee drm/i915/dp: Fix DP MST error after unplugging TypeC cable
This patch avoids DP MST payload error message in dmesg, as it is trying
to update the payload to the disconnected DP MST device. After DP MST
device is disconnected we should not be updating the payload and
hence remove the error.

v2: Removed the connector status check and converted from error to debug.

dfef959803 drm/tiny: Kconfig: Remove always-y THERMAL dep. from TINYDRM_REPAPER
Commit 554b3529fe ("thermal/drivers/core: Remove the module Kconfig's
option") changed the type of THERMAL from tristate to bool, so
THERMAL || !THERMAL is now always y. Remove the redundant dependency.

Discovered through Kconfiglib detecting a dependency loop. The C tools
simplify the expression to y before running dependency loop detection,
and so don't see it. Changing the type of THERMAL back to tristate makes
the C tools detect the same loop.

Not sure if running dep. loop detection after simplification can be
called a bug. Fixing this nit unbreaks Kconfiglib on the kernel at
least.

1d6f1d16d3 drm/i915/gt: Only unwedge if we can reset first
Unwedging the GPU requires a successful GPU reset before we restore the
default submission, or else we may see residual context switch events
that we were not expecting.

v2: Pull in the special-case reset_clobbers_display, and explain why it
should be safe in the context of unwedging.

v3: Just forget all about resets before unwedging if it will clobber the
display; risk it all.

50d16d44cc drm/i915/selftests: Exercise context switching in parallel
We currently test context switching on each engine as a basic stress
test (just verifying that nothing explodes if we execute 2 requests from
different contexts sequentially). What we have not tested is what
happens if we try and do so on all available engines simultaneously,
putting our SW and the HW under the maximal stress.

v2: Clone the set of engines from the first context into the secondary

a839136ca4 drm/i915/tgl: Fix dkl link training
Link training is failling when running link at 2.7GHz and 1.62GHz and
following BSpec pll algorithm.

Comparing the values calculated and the ones from the reference table
it looks like MG_CLKTOP2_CORECLKCTL1_A_DIVRATIO should not always set
to 5. For DP ports ICL mg pll algorithm sets it to 10 or 5 based on
div2 value, that matches with dkl hardcoded table.

So implementing this way as it proved to work in HW and leaving a
comment so we know why it do not match BSpec.

v4:
Using the same is_dp check as ICL, need testing on HDMI over tc port

The HuC FW has silently switched to encoding the version the same way as
the GuC FW does, i.e. major.minor.patch instead of just major.minor. All
the current blobs follow the new scheme, but since minor and patch are
both zero there is no difference in the end results and we happily load
them. New binaries, however, will have non-zero values in there, so we
need to make sure to parse them correctly.

d6cb013579 drm/komeda: SW workaround for D71 doesn't flush shadow registers
This is a SW workaround for shadow un-flushed when together with the
DOU Timing-disable.

D71 HW doesn't update shadow registers when display output is turned
off. So when we disable all pipeline components together with display
output disabling by one flush or one operation, the disable operation
updated registers will not be flushed or valid in HW, which may lead
problem. To workaround this problem, introduce a two phase disable for
pipeline disable.

Phase1: Disable components with display is on and flush it, this phase
        for flushing or validating the shadow registers.
Phase2: Turn-off display output.

245f44e771 drm/vram: Support top-down placement flag
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.

e3792238c1 drm/i915: Don't disable interrupts for intel_engine_breadcrumbs_irq()
The function intel_engine_breadcrumbs_irq() is always invoked from an interrupt
handler and for that reason it invokes (as an optimisation) only spin_lock()
for locking assuming that the interrupts are already disabled. The
function intel_engine_signal_breadcrumbs() is provided to disable
interrupts while the former function is invoked so that assumption is
also true for callers from preemptible context.

On PREEMPT_RT local_irq_disable() really disables interrupts and this
forbids to invoke spin_lock() which becomes a sleeping spinlock.

This is also problematic with `threadirqs' in conjunction with
irq_work. With force threading the interrupt handler, the handler is
invoked with disabled BH but with interrupts enabled. This is okay and
the lock itself is never acquired in IRQ context. This changes with
irq_work (signal_irq_work()) which _still_ invokes
intel_engine_breadcrumbs_irq() from IRQ context. Lockdep should see this
and complain.

Acquire the locks in intel_engine_breadcrumbs_irq() with _irqsave()
suffix and let all callers invoke intel_engine_breadcrumbs_irq()
directly instead using intel_engine_signal_breadcrumbs().

132dfc78d3 drm/i915: Drop the IRQ-off asserts
The lockdep_assert_irqs_disabled() check is needless. The previous
lockdep_assert_held() check ensures that the lock is acquired and while
the lock is acquired lockdep also prints a warning if the interrupts are
not disabled if they have to be.
These IRQ-off asserts trigger on PREEMPT_RT because the locks become
sleeping locks and do not really disable interrupts.

Remove lockdep_assert_irqs_disabled().

45d3c5cd52 drm/i915: Small joiner RAM buffer size is platform-specific
According to the bspec, GLK/CNL have a smaller small joiner RAM buffer
than ICL+.  This feels like something that could easily change again on
future platforms, so let's just add a function to return the proper
per-platform buffer size.  That may also slightly simplify the upcoming
bigjoiner enabling.

Since we have to change intel_dp_dsc_get_output_bpp()'s signature to
pass the dev_priv down for the platform check, let's take the
opportunity to also make that function static since it isn't used
outside the intel_dp file.

tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

In radeon_gem_userptr_ioctl() an MMU notifier is set up with a (tagged)
userspace pointer.  The untagged address should be used so that MMU
notifiers for the untagged address get correctly matched up with the right
BO.  This funcation also calls radeon_ttm_tt_pin_userptr(), which uses
provided user pointers for vma lookups, which can only by done with
untagged pointers.

This patch untags user pointers in radeon_gem_userptr_ioctl().

e2839ff692 drm/dp_mst: Rename drm_dp_add_port and drm_dp_update_port
The names for these functions are rather confusing. drm_dp_add_port()
sounds like a function that would simply create a port and add it to a
topology, and do nothing more. Similarly, drm_dp_update_port() would be
assumed to be the function that should be used to update port
information after initial creation.

While those assumptions are currently correct in how these functions are
used, a quick glance at drm_dp_add_port() reveals that drm_dp_add_port()
can also update the information on a port, and seems explicitly designed
to do so. This can be explained pretty simply by the fact that there's
more situations that would involve updating the port information based
on a link address response as opposed to a connection status
notification than the driver's initial topology probe. Case in point:
reprobing link addresses after suspend/resume.

Since we're about to start using drm_dp_add_port() differently for
suspend/resume reprobing, let's rename both functions to clarify what
they actually do.

be different for DKL PHY. Prepare for that by reindenting code so it's
easier to check for correctness. This one has no change in behavior.

ed06efb801 drm/i915/dp: Fix dsc bpp calculations, v5.
There was a integer wraparound when mode_clock became too high,
and we didn't correct for the FEC overhead factor when dividing,
with the calculations breaking at HBR3.

As a result our calculated bpp was way too high, and the link width
limitation never came into effect.

Print out the resulting bpp calcululations as a sanity check, just
in case we ever have to debug it later on again.

We also used the wrong factor for FEC. While bspec mentions 2.4%,
all the calculations use 1/0.972261, and the same ratio should be
applied to data M/N as well, so use it there when FEC is enabled.

This fixes the FIFO underrun we are seeing with FEC enabled.

Changes since v2:
- Handle fec_enable in intel_link_compute_m_n, so only data M/N is adjusted. (Ville)
- Fix initial hardware readout for FEC. (Ville)
Changes since v3:
- Remove bogus fec_to_mode_clock. (Ville)
Changes since v4:
- Use the correct register for icl. (Ville)
- Split hw readout to a separate patch.

Since dropping the set-to-gtt-domain in commit a679f58d05 ("drm/i915:

dirty on releasing the buffer, which means the contents are not written
out to the swap device (should we ever pick that buffer as a victim).
Notably, this is visible in the dumb buffer interface used for cursors.
Having updated the cursor contents via mmap, and swapped away, if the
shrinker should evict the old cursor, upon next reuse, the cursor would
be invisible.

e2144503bf drm/i915: Prevent bonded requests from overtaking each other on preemption
Force bonded requests to run on distinct engines so that they cannot be
shuffled onto the same engine where timeslicing will reverse the order.
A bonded request will often wait on a semaphore signaled by its master,
creating an implicit dependency -- if we ignore that implicit dependency
and allow the bonded request to run on the same engine and before its
master, we will cause a GPU hang. [Whether it will hang the GPU is
debatable, we should keep on timeslicing and each timeslice should be
"accidentally" counted as forward progress, in which case it should run
but at one-half to one-third speed.]

We can prevent this inversion by restricting which engines we allow
ourselves to jump to upon preemption, i.e. baking in the arrangement
established at first execution. (We should also consider capturing the
implicit dependency using i915_sched_add_dependency(), but first we need
to think about the constraints that requires on the execution/retirement
ordering.)

cb2377a919 drm/i915: Fixup preempt-to-busy vs reset of a virtual request
Due to the nature of preempt-to-busy the execlists active tracking and
the schedule queue may become temporarily desync'ed (between resubmission
to HW and its ack from HW). This means that we may have unwound a
request and passed it back to the virtual engine, but it is still
inflight on the HW and may even result in a GPU hang. If we detect that
GPU hang and try to reset, the hanging request->engine will no longer
match the current engine, which means that the request is not on the
execlists active list and we should not try to find an older incomplete
request. Given that we have deduced this must be a request on a virtual
engine, it is the single active request in the context and so must be
guilty (as the context is still inflight, it is prevented from being
executed on another engine as we process the reset).

b647c7df01 drm/i915: Fixup preempt-to-busy vs resubmission of a virtual request
As preempt-to-busy leaves the request on the HW as the resubmission is
processed, that request may complete in the background and even cause a
second virtual request to enter queue. This second virtual request
breaks our "single request in the virtual pipeline" assumptions.
Furthermore, as the virtual request may be completed and retired, we
lose the reference the virtual engine assumes is held. Normally, just
removing the request from the scheduler queue removes it from the
engine, but the virtual engine keeps track of its singleton request via
its ve->request. This pointer needs protecting with a reference.

31d9ae9d73 drm/i915/tgl: Finish modular FIA support on registers
If platform supports and has modular FIA is enabled, the registers
bits also change, example: reading TC3 registers with modular FIA
enabled, driver should read from FIA2 but with TC1 bits offsets.

It is described in BSpec 50231 for DFLEXDPSP, other registers don't
have the BSpec description but testing in real hardware have proven
that it had moved for all other registers too.

v2:
- Caching index in tc_phy_fia_idx, instead of calculate it each time

v3:
- Setting tc_phy_fia and tc_phy_fia_idx in the same function

ae911b23d2 drm/i915/execlists: Relax assertion for a pinned context image on reset
A gpu hang can occur at any time, given a sufficiently angry gpu. An
example is when it forgets to perform a context-switch at the end of a
request, leaving us with a hanging GPU on a completed request. Here, we
may retire the request, only leaving its context alive via the active
barrier. When we reset the GPU on a completed request, we do not modify
its context image (just updating the ring state) and can safely defer
the assertion that we have the image pinned and ready to modify.

84af764918 drm/i915/color: Extract icl_read_luts()
For icl+, have hw read out to create hw blob of gamma
lut values. icl+ platforms supports multi segmented gamma
mode by default, add hw lut creation for this mode.

This will be used to validate gamma programming using dsb
(display state buffer) which is a tgl specific feature.

Major change done-removal of readouts of coarse and fine segments
because PAL_PREC_DATA register isn't giving propoer values.
State checker limited only to "fine segment"

v2: -readout code for multisegmented gamma has to come
     up with some intermediate entries that aren't preserved
     in hardware (Jani N)
    -linear interpolation (Ville)
    -moved common code to check gamma_enable to specific funcs,
     since icl doesn't support that
v3: -use u16 instead of __u16 [Jani N]
    -used single lut [Jani N]
    -improved and more readable for loops [Jani N]
    -read values directly to actual locations and then fill gaps [Jani N]
    -moved cleaning to patch 1 [Jani N]
    -renamed icl_read_lut_multi_seg() to icl_read_lut_multi_segment to
     make it similar to icl_load_luts()
    -renamed icl_compute_interpolated_gamma_blob() to
     icl_compute_interpolated_gamma_lut_values() more sensible, I guess
v4: -removed interpolated func for creating gamma lut values
    -removed readouts of fine and coarse segments, failure to read PAL_PREC_DATA
     correctly

The "lvds->backlight" pointer could be NULL in situations where
of_parse_phandle() returns NULL.  This code is cleaner if we use the

84da111de0 hmm related patches for 5.4
This is more cleanup and consolidation of the hmm APIs and the very
 strongly related mmu_notifier interfaces. Many places across the tree
 using these interfaces are touched in the process. Beyond that a cleanup
 to the page walker API and a few memremap related changes round out the
 series:
 
 - General improvement of hmm_range_fault() and related APIs, more
   documentation, bug fixes from testing, API simplification &
   consolidation, and unused API removal
 
 - Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE, and
   make them internal kconfig selects
 
 - Hoist a lot of code related to mmu notifier attachment out of drivers by
   using a refcount get/put attachment idiom and remove the convoluted
   mmu_notifier_unregister_no_release() and related APIs.
 
 - General API improvement for the migrate_vma API and revision of its only
   user in nouveau
 
 - Annotate mmu_notifiers with lockdep and sleeping region debugging
 
 Two series unrelated to HMM or mmu_notifiers came along due to
 dependencies:
 
 - Allow pagemap's memremap_pages family of APIs to work without providing
   a struct device
 
 - Make walk_page_range() and related use a constant structure for function
   pointers

Gen12 has dual-subslices (DSS), which compared to gen11 subslices have
some duplicated resources/paths. Although DSS behave similarly to 2
subslices, instead of splitting this and presenting userspace with bits
not directly representative of hardware resources, present userspace
with a subslice_mask made up of DSS bits instead.

d1844606fd drm/i915: Add PIPECONF YCbCr 4:4:4 programming for ILK-IVB
On ILK-IVB the pipe colorspace is configured via PIPECONF
(as opposed to PIPEMISC in BDW+). Let's configure+readout
that stuff correctly.

Enabling YCbCr 4:4:4 output will now be a simple matter of
setting crtc_state->output_format appropriately in the encoder
.compute_config(). However, when we do that we must be
aware of the fact that YCbCr DP output doesn't seem to work
on ILK (resulting image is totally garbled), but on SNB+
it works fine. However HDMI YCbCr output does work correctly
even on ILK.

af28cc4c28 drm/i915: Set up ILK/SNB csc unit properly for YCbCr output
Prepare the pipe csc for YCbCr output on ilk/snb. The main difference
to IVB+ is the lack of explicit post offsets, and instead we must
configure the CSC info RGB->YUV mode (which takes care of offsetting
Cb/Cr properly) and enable the "black screen offset" bit to add the
required offset to Y.

And while at it throw some comments around the bit defines to
document which platforms have which bits.

60a02311cc drm/i915: Don't look at unrelated PIPECONF bits for interlaced readout
Since HSW the PIPECONF progressive vs. interlaced selection is done
with just two bits instead of the earlier three. Let's not look at the
extra bit on HSW+. Also gen2 doesn't support interlaced displays at all.

This is actually fine as is currently because the extra bit is mbz (as
are all three bits on gen2). But just to avoid mishaps in the future
if the bits get reused let's only look at what's properly defined.

cae154fcae drm/i915: Never set limited_color_range=true for YCbCr output
crtc_state->limited_color_range only applies to RGB output but
we're currently setting it even for YCbCr output. That will
lead to conflicting MSA and PIPECONF settings which can mess
up the image. Let's make sure limited_color_range stays unset
with YCbCr output.

Also WARN if we end up with such a bogus combination when
programming the MSA MISC bits as it's impossible to even
indicate quantization rangle for YCbCr via MSA MISC. YCbCr
output is simply assumed to be limited range always. Note
that VSC SDP does provide a mechanism for full range YCbCr,
so in the future we may want to rethink how we compute/store
this state.

And for good measure we add the same WARN to the HDMI path.

e5de91e68c Revert "drm/i915/tgl: Implement Wa_1406941453"
Our sanitychecks indicate that while this register is context
saved/restore, the HW does not preserve this bit within the register --
it likely doesn't exist, or one of those mythical bits that the
architects insist does something despite all appearances to the
contrary.

For reference, SAMPLER_MODE is already in i915_reg.h as
GEN10_SAMPLER_MODE and is being setup in icl_ctx_workarounds_init() as
opposed to the chosen location here of rcs_engine_wa_init).

9eee0dd7d3 drm/i915: Protect timeline->hwsp dereferencing
As not only is the signal->timeline volatile, so will be acquiring the
timeline's HWSP. We must first carefully acquire the timeline from the
signaling request and then lock the timeline. With the removal of the
struct_mutex serialisation of request construction, we can have multiple
timelines active at once, and so we must avoid using the nested mutex
lock as it is quite possible for both timelines to be establishing
semaphores on the other and so deadlock.

6a79d84840 drm/i915: Lock signaler timeline while navigating
As we need to take a walk back along the signaler timeline to find the
fence before upon which we want to wait, we need to lock that timeline
to prevent it being modified as we walk. Similarly, we also need to
acquire a reference to the earlier fence while it still exists!

Though we lack the correct locking today, we are saved by the
overarching struct_mutex -- but that protection is being removed.

v2: Tvrtko made me realise I was being lax and using annotations to
ignore the AB-BA deadlock from the timeline overlap. As it would be
possible to construct a second request that was using a semaphore from the
same timeline as ourselves, we could quite easily end up in a situation
where we deadlocked in our mutex waits. Avoid that by using a trylock
and falling back to a normal dma-fence await if contended.

v3: Eek, the signal->timeline is volatile and must be carefully
dereferenced to ensure it is valid.

d19d71fc2b drm/i915: Mark i915_request.timeline as a volatile, rcu pointer
The request->timeline is only valid until the request is retired (i.e.
before it is completed). Upon retiring the request, the context may be
unpinned and freed, and along with it the timeline may be freed. We
therefore need to be very careful when chasing rq->timeline that the
pointer does not disappear beneath us. The vast majority of users are in
a protected context, either during request construction or retirement,
where the timeline->mutex is held and the timeline cannot disappear. It
is those few off the beaten path (where we access a second timeline) that
need extra scrutiny -- to be added in the next patch after first adding
the warnings about dangerous access.

One complication, where we cannot use the timeline->mutex itself, is
during request submission onto hardware (under spinlocks). Here, we want
to check on the timeline to finalize the breadcrumb, and so we need to
impose a second rule to ensure that the request->timeline is indeed
valid. As we are submitting the request, it's context and timeline must
be pinned, as it will be used by the hardware. Since it is pinned, we
know the request->timeline must still be valid, and we cannot submit the
idle barrier until after we release the engine->active.lock, ergo while
submitting and holding that spinlock, a second thread cannot release the
timeline.

v2: Don't be lazy inside selftests; hold the timeline->mutex for as long
as we need it, and tidy up acquiring the timeline with a bit of
refactoring (i915_active_add_request)

c45e788d95 drm/i915/tgl: Suspend pre-parser across GTT invalidations
Before we execute a batch, we must first issue any and all TLB
invalidations so that batch picks up the new page table entries.
Tigerlake's preparser is weakening our post-sync CS_STALL inside the
invalidate pipe-control and allowing the loading of the batch buffer
before we have setup its page table (and so it loads the wrong page and
executes indefinitely).

The igt_cs_tlb indicates that this issue can only be observed on rcs,
even though the preparser is common to all engines. Alternatively, we
could do TLB shootdown via mmio on updating the GTT.

By inserting the pre-parser disable inside EMIT_INVALIDATE, we will also
accidentally fixup execution that writes into subsequent batches, such
as gem_exec_whisper and even relocations performed on the GPU. We should
be careful not to allow this disable to become baked into the uABI! The
issue is that if userspace relies on our disabling of the HW
optimisation, when we are ready to enable that optimisation, userspace
will then be broken...

Extends the user space ioctl for CL submissions so it can include a request
to flush the cache once the CL execution has completed. Fixes memory
write violation messages reported by the kernel in workloads involving
shader memory writes (SSBOs, shader images, scratch, etc) which sometimes
also lead to GPU resets during Piglit and CTS workloads.

v2: if v3d_job_init() fails we need to kfree() the job instead of
    v3d_job_put() it (Eric Anholt).

v3 (Eric Anholt):
  - Drop _FLAG suffix from the new flag name.
  - Add a new param so userspace can tell whether cache flushing is
    implemented in the kernel.

2d20411e25 drm/i915: Don't advertise modes that exceed the max plane size
Modern platforms allow the transcoders hdisplay/vdisplay to exceed the
planes' max resolution. This has the nasty implication that modes on the
connectors' mode list may not be usable when the user asks for a
fullscreen plane. Seeing as that is the most common use case it seems
prudent to filter out modes that don't allow for fullscreen planes to
be enabled.

Let's do that in the connetor .mode_valid() hook so that normally
such modes are kept hidden but the user is still able to forcibly
specify such a mode if they know they don't need fullscreen planes.

This is in line with ealier policies regarding certain clock limits.
The idea is to prevent the casual user from encountering a mode that
would fail under typical conditions, but allow the expert user to
force things if they so wish.

Maybe in the future we should consider automagically using two
planes when one can't cover the entire screen? Wouldn't be a
great match for the current uapi with explicit planes though,
but I guess no worse than using two pipes (which we apparently
have to in the future anyway). Either that or we'd have to
teach userspace to do it for us.

bed34ef544 drm/i915: Bump skl+ max plane width to 5k for linear/x-tiled
The officially validated plane width limit is 4k on skl+, however
we already had people using 5k displays before we started to enforce
the limit. Also it seems Windows allows 5k resolutions as well
(though not sure if they do it with one plane or two).

According to hw folks 5k should work with the possible
exception of the following features:
- Ytile (already limited to 4k)
- FP16 (already limited to 4k)
- render compression (already limited to 4k)
- KVMR sprite and cursor (don't care)
- horizontal panning (need to verify this)
- pipe and plane scaling (need to verify this)

So apart from last two items on that list we are already
fine. We should really verify what happens with those last
two items but I don't have a 5k display on hand atm so it'll
have to wait.

In the meantime let's just bump the limit back up to 5k since
several users have already been using it without apparent issues.
At least we'll be no worse off than we were prior to lowering
the limits.

65e51e30d8 drm/panfrost: Prevent race when handling page fault
When handling a GPU page fault addr_to_drm_mm_node() is used to
translate the GPU address to a buffer object. However it is possible for
the buffer object to be freed after the function has returned resulting
in a use-after-free of the BO.

Change addr_to_drm_mm_node to return the panfrost_gem_object with an
extra reference on it, preventing the BO from being freed until after
the page fault has been handled.

edfa07504c drm/panfrost: Fix regulator_get_optional() misuse
The panfrost driver requests a supply using regulator_get_optional()
but both the name of the supply and the usage pattern suggest that it is
being used for the main power for the device and is not at all optional
for the device for function, there is no meaningful handling for absent
supplies.  Such regulators should use the vanilla regulator_get()
interface, it will ensure that even if a supply is not described in the
system integration one will be provided in software.

The MCC hpd table is just a subset of the ICP table; we can eliminate it

b01a3ef348 drm/i915: Future-proof DDC pin mapping
We generally assume future platforms will inherit the behavior of the
most recent platforms, so update our DDC pin mapping defaults to match
how ICP/TGP behave (i.e., pins starting from GMBUS_PIN_1_BXT for combo
PHY's and pins starting from GMBUS_PIN_9_TC1_ICP for TC PHY's).  MCC's
non-standard handling of combo PHY C seems like a platform-specific
quirk that is unlikely to be duplicated on future platforms, so continue
handling it as a special case.

Without this change, future platforms would default to gen4-style pin
mapping which is almost certainly not what we'll want.

d4da4e3334 drm: Measure Self Refresh Entry/Exit times to avoid thrashing
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

37fa0de3c1 drm/i915: Verify the engine after acquiring the active.lock
When using virtual engines, the rq->engine is not stable until we hold
the engine->active.lock (as the virtual engine may be exchanged with the
sibling). Since commit 22b7a426bb ("drm/i915/execlists: Preempt-to-busy")
we may retire a request concurrently with resubmitting it to HW, we need
to be extra careful to verify we are holding the correct lock for the
request's active list. This is similar to the issue we saw with
rescheduling the virtual requests, see sched_lock_engine().

0d333ac7eb drm/i915: fix SFC reset flow
Our assumption that the we can ask the HW to lock the SFC even if not
currently in use does not match the HW commitment. The expectation from
the HW is that SW will not try to lock the SFC if the engine is not
using it and if we do that the behavior is undefined; on ICL the HW
ends up to returning the ack and ignoring our lock request, but this is
not guaranteed and we shouldn't expect it going forward.

Also, failing to get the ack while the SFC is in use means that we can't
cleanly reset it, so fail the engine reset in that scenario.

v2: drop rmw change, keep the log as debug and handle failure (Chris),
    improve comments (Tvrtko).

the atomic ioctl might need a different flag for async flips. So
better to abstract this away from the uapi a bit.

f2cbda2dba drm/atomic: Reject FLIP_ASYNC unconditionally
It's never been wired up. Only userspace that tried to use it (and
didn't actually check whether anything works, but hey it builds) is
the -modesetting atomic implementation. And we just shut that up.

If there's anyone else then we need to silently accept this flag no
matter what, and find a new one. Because once a flag is tainted, it's
lost.

26b1d3b527 drm/atomic: Take the atomic toys away from X
The -modesetting ddx has a totally broken idea of how atomic works:
- doesn't disable old connectors, assuming they get auto-disable like
  with the legacy setcrtc
- assumes ASYNC_FLIP is wired through for the atomic ioctl
- not a single call to TEST_ONLY

Iow the implementation is a 1:1 translation of legacy ioctls to
atomic, which is a) broken b) pointless.

We already have bugs in both i915 and amdgpu-DC where this prevents us
from enabling neat features.

If anyone ever cares about atomic in X we can easily add a new atomic
level (req->value == 2) for X to get back the shiny toys.

Since these broken versions of -modesetting have been shipping,
there's really no other way to get out of this bind.

v2:
- add an informational dmesg output (Rob, Ajax)
- reorder after the DRIVER_ATOMIC check to avoid useless noise (Ilia)
- allow req->value > 2 so that X can do another attempt at atomic in
  the future

v3: Go with paranoid, insist that the X should be first (suggested by
Rob)

56c05de6bd drm/i915: Extend Haswell GT1 PSMI workaround to all
A few times in CI, we have detected a GPU hang on our Haswell GT2
systems with the characteristic IPEHR of 0x780c0000. When the PSMI w/a
was first introducted, it was applied to all Haswell, but later on we
found an erratum that supposedly restricted the issue to GT1 and so
constrained it only be applied on GT1. That may have been a mistake...

e0f32f78e5 drm/kms: Duct-tape for mode object lifetime checks
commit 4f5368b554
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Jun 14 08:17:23 2019 +0200

    drm/kms: Catch mode_object lifetime errors

uncovered a bit a mess in dp drivers. Most drivers (from a quick look,
all except i915) register all the dp stuff in their init code, which
is too early. With CONFIG_DRM_DP_AUX_CHARDEV this will blow up,
because drm_dp_aux_register tries to add a child to a device in sysfs
(the connector) which doesn't even exist yet.

No one seems to have cared thus far. But with the above change I also
moved the setting of dev->registered after the ->load callback, in an
attempt to keep old drivers from hitting any WARN_ON backtraces. But
that moved radeon.ko from the "working, by accident" to "now also
broken" category.

Since this is a huge mess I figured a revert would be simplest. But
this check has already caught issues in i915:

commit 1b9bd09630
Author: Ville Syrjälä <ville.syrjala@linux.intel.com>
Date:   Tue Aug 20 19:16:57 2019 +0300

    drm/i915: Do not create a new max_bpc prop for MST connectors

Hence I'd like to retain it. Fix the radeon regression by moving the
setting of dev->registered back to were it was, and stop the
backtraces with an explicit check for dev->driver->load.

Everyone else will stay as broken with CONFIG_DRM_DP_AUX_CHARDEV. The
next patch will improve the kerneldoc and add a todo entry for this.

Merge tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "In this cycle we've finally managed to contribute the patch set
  sorting out LED naming issues. Besides that there are many changes
  scattered among various LED class drivers and triggers.

  LED naming related improvements:

   - add new 'function' and 'color' fwnode properties and deprecate
     'label' property which has been frequently abused for conveying
     vendor specific names that have been available in sysfs anyway

   - introduce a set of standard LED_FUNCTION* definitions

   - introduce a set of standard LED_COLOR_ID* definitions

   - add a new {devm_}led_classdev_register_ext() API with the
     capability of automatic LED name composition basing on the
     properties available in the passed fwnode; the function is
     backwards compatible in a sense that it uses 'label' data, if
     present in the fwnode, for creating LED name

   - add tools/leds/get_led_device_info.sh script for retrieving LED
     vendor, product and bus names, if applicable; it also performs
     basic validation of an LED name

   - update following drivers and their DT bindings to use the new LED
     registration API:

        - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
          leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt

  Other LED class improvements:

   - replace {devm_}led_classdev_register() macros with inlines

   - allow to call led_classdev_unregister() unconditionally

   - switch to use fwnode instead of be stuck with OF one

  LED triggers improvements:

   - led-triggers:
        - fix dereferencing of null pointer
        - fix a memory leak bug

   - ledtrig-gpio:
        - GPIO 0 is valid

  Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
  more complete driver exists, based on a generic driver for the AMD
  SOCs gpio-controller, supporting LEDs as well other devices:

   - drop profile field from priv data

   - drop iosize field from priv data

   - drop enum_apu_led_platform_types

   - drop superseeded apu2/3 led support

   - add pr_fmt prefix for better log output

   - fix error message on probing failure

  Other misc fixes and improvements to existing LED class drivers:

   - leds-ns2, leds-max77650:
        - add of_node_put() before return

   - leds-pwm, leds-is31fl32xx:
        - use struct_size() helper

   - leds-lm3697, leds-lm36274, leds-lm3532:
        - switch to use fwnode_property_count_uXX()

   - leds-lm3532:
        - fix brightness control for i2c mode
        - change the define for the fs current register
        - fixes for the driver for stability
        - add full scale current configuration
        - dt: Add property for full scale current.
        - avoid potentially unpaired regulator calls
        - move static keyword to the front of declarations
        - fix optional led-max-microamp prop error handling

   - leds-max77650:
        - add of_node_put() before return
        - add MODULE_ALIAS()
        - Switch to fwnode property API

   - leds-as3645a:
        - fix misuse of strlcpy

   - leds-netxbig:
        - add of_node_put() in netxbig_leds_get_of_pdata()
        - remove legacy board-file support

   - leds-is31fl319x:
        - simplify getting the adapter of a client

   - leds-ti-lmu-common:
        - fix coccinelle issue
        - move static keyword to the front of declaration

   - leds-syscon:
        - use resource managed variant of device register

   - leds-ktd2692:
        - fix a typo in the name of a constant

   - leds-lp5562:
        - allow firmware files up to the maximum length

   - leds-an30259a:
        - fix typo

   - leds-pca953x:
        - include the right header"

Bail from the pci_driver probe function instead of from the drm_driver
load function.

This avoid /dev/dri/card0 temporarily getting registered and then
unregistered again, sending unwanted add / remove udev events to
userspace.

Specifically this avoids triggering the (userspace) bug fixed by this
plymouth merge-request:
https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59

Note that despite that being an userspace bug, not sending unnecessary
udev events is a good idea in general.

c02d6a1613 drm/amd/display: Add missing HBM support and raise Vega20's uclk.
[Why]
When more than 2 displays are connected to the graphics card,
only the minimum memory clock is needed. However, when more
displays are connected, the minimum memory clock is not
sufficient enough to support the overwhelming bandwidth.
System will hang under this circumstance.

Also, the old code didn't address HBM cards, which has 2
pseudo channels. We need to add the HBM part here.

[How]
When graphics card connects to 2 or more displays,
switch to high memory clock. Also, choose memory
multiplier based on whether its regular DRAM or HBM.

b568db62c5 drm/nouveau/bar/gm20b: Avoid BAR1 teardown during init
Writing the 0x1704 (BUS_BAR1_BLOCK) register causes the GPU to probe the
memory region at the programmed address. The result is an address decode
error in the external memory controller because address 0, which is what
is written to the register, is not designated as accessible to devices.

Avoid triggering DMA from the GPU by removing teardown of the BAR1.

641f53c07d drm/nouveau: Fix ordering between TTM and GEM release
When the last reference to a TTM BO is dropped, ttm_bo_release() will
acquire the DMA reservation object's wound/wait mutex while trying to
clean up (ttm_bo_cleanup_refs_or_queue() via ttm_bo_release()). It is
therefore essential that drm_gem_object_release() be called after the
TTM BO has been uninitialized, otherwise drm_gem_object_release() has
already destroyed the wound/wait mutex (via dma_resv_fini()).

0bb21c9677 drm/nouveau/prime: Extend DMA reservation object lock
Prior to commit 019cbd4a4f ("drm/nouveau: Initialize GEM object before
TTM object"), the reservation object was locked across all of the buffer
object creation.

After splitting nouveau_bo_new() into separate nouveau_bo_alloc() and
nouveau_bo_init() functions, the reservation object is passed to the
latter, so the lock needs to be held across that function as well.

9ca7f7968b drm/nouveau: Fix fallout from reservation object rework
Commit 019cbd4a4f ("drm/nouveau: Initialize GEM object before TTM
object") introduced a subtle change in how the buffer allocation size is
handled. Prior to that change, the size would get aligned to at least a
page, whereas after that change a non-page-aligned size would get passed
through unmodified. This ultimately causes a BUG_ON() to trigger in
drm_gem_private_object_init() and crashes the system.

Fix this by restoring the code that align the allocation size.

698c1aa9f8 drm/nouveau/kms/nv50-: Don't create MSTMs for eDP connectors
On the ThinkPad P71, we have one eDP connector exposed along with 5 DP
connectors, resulting in a total of 11 TMDS encoders. Since the GPU on
this system is also capable of MST, we create an additional 4 fake MST
encoders for each DP port. Unfortunately, we also do this for the eDP
port as well, resulting in:

  1 eDP port: +1 TMDS encoder
              +4 DPMST encoders
  5 DP ports: +2 TMDS encoders
              +4 DPMST encoders
	      *5 ports
	      == 35 encoders

Which breaks things, since DRM has a hard coded limit of 32 encoders.
So, fix this by not creating MSTMs for any eDP connectors. This brings
us down to 31 encoders, although we can do better.

This fixes driver probing for nouveau on the ThinkPad P71.

ef404bc659 drm/i915: stop conflating HAS_DISPLAY() and disabled display
Stop setting ->pipe_mask to zero when display is disabled, allowing us
to have different code paths for not actually having display hardware,
and having display hardware disabled. This lets us develop those two
avenues independently.

There are no functional changes for when there is no display. However,
all uses of for_each_pipe() and for_each_pipe_masked() will start
running for the disabled display case. Put one of the more significant
ones behind checks for INTEL_DISPLAY_ENABLED(), otherwise the cases
should not be hit with disabled display, or they seem benign. Fingers
crossed.

All in all, this might not be the ideal solution. In fact we may have
had something along the lines of this in the past, but we ended up
conflating the two cases. Possibly even by recommendation by yours
truly; I did not dare dig up that part of the history. But the perfect
is the enemy of the good, this is a straightforward change, and lets us
get actual work done in both fronts without interfering with each other.

a2b69ea4d2 drm/i915: introduce INTEL_DISPLAY_ENABLED()
Prepare for making a distinction between not having display and having
disabled display. Add INTEL_DISPLAY_ENABLED() and use it where
HAS_DISPLAY() is used after intel_device_info_runtime_init(). This is
initially duplication, as disabling display still leads to ->pipe_mask =
0 and HAS_DISPLAY() being false.

Note that ever since i915.display_disable was introduced, it has not
affected PCH detection even if it uses HAS_DISPLAY(), as display disable
happens after that.

Since INTEL_DISPLAY_ENABLED() will not make sense unless HAS_DISPLAY()
is true, include a warning for catching misuses making decisions on
INTEL_DISPLAY_ENABLED() when HAS_DISPLAY() is false.

v2: Remove INTEL_DISPLAY_ENABLED() check from intel_detect_pch() (Chris)

3250cdf938 drm: bridge/dw_hdmi: add audio sample channel status setting
When transmitting IEC60985 linear PCM audio, we configure the
Aduio Sample Channel Status information in the IEC60958 frame.
The status bit is already available in iec.status of hdmi_codec_params.

This fix the issue that audio does not come out on some monitors
(e.g. LG 22CV241)

Note that these registers are only for interfaces:
I2S audio interface, General Purpose Audio (GPA), or AHB audio DMA
(AHBAUDDMA).
For S/PDIF interface this information comes from the stream.

Currently this function dw_hdmi_set_channel_status is only called
from dw-hdmi-i2s-audio in I2S setup.

2472518e44 Revert "drm/bridge: adv7511: Attach to DSI host at probe time"
This reverts commit 83f35bc3a8.

There are at least two DSI controller drivers which relies on the old
behaviour of adv7511 driver. To avoid platform breakage this patch
should be reverted. This is a temporary solution, as it blocks adv7511
usage with other platforms.
Assumption that DSI device driver (bridge/panel) should first expose
drm_bridge/drm_panel object, then look for DSI bus is just incorrect -
it can work with devices controlled via i2c but it cannot work with
devices controlled via DSI - they will not be able to probe.
To solve the issue following steps should be performed:
- rework reverted patch allowing co-operation with broken DSI controller
  drivers - with simple/ugly workaround,
- fix controller drivers and then remove workaround.

ee73e2795b drm/i915/tgl: Disable preemption while being debugged
We see failures where the context continues executing past a
preemption event, eventually leading to situations where a request has
executed before we have event submitted it to HW! It seems like tgl is
ignoring our RING_TAIL updates, but more likely is that there is a
missing update required for our semaphore waits around preemption.

v2: And disable internal semaphore usage

54fc577d90 drm/i915/pmu: Skip busyness sampling when and where not needed
Since d0aa694b92 ("drm/i915/pmu: Always sample an active ringbuffer")
the cost of sampling the engine state on execlists platforms became a
little bit higher when both engine busyness and one of the wait states are
being monitored. (Previously the busyness sampling on legacy platforms was
done via seqno comparison so there was no cost of mmio read.)

We can avoid that by skipping busyness sampling when engine supports
software busy stats and so avoid the cost of potential mmio read and
sample accumulation.

The only difference in between the cnl/icl and the bxt variants
is the call to cnl_compute_min_voltage_level(). We can do that call
just fine on older platforms since they leave min_voltage_level[]
zeroed. Let's rename the function to bxt_compute_min_voltage_level()

0a12e43704 drm/i915: Fix CD2X pipe select masking during cdclk sanitation
We're forgetting to mask off all three pipe select bits from the
CDCLK_CTL value on icl+ which may lead to the extra bit being
left in. That will cause us to consider the current hardware
cdclk state as invalid, and we proceed to sanitize it even
though the hardware may have active pipes and whatnot.

Fix up the mask so we get rid of all three pipe select bits
and thus hopefully no longer sanitize cdclk when it's already
correctly programmed.

736da8112f drm/i915: Use literal representation of cdclk tables
The bspec lays out legal cdclk frequencies, PLL ratios, and CD2X
dividers in an easy-to-read table for most recent platforms.  We've been
translating the data from that table into platform-specific code logic,
but it's easy to overlook an area we need to update when adding new
cdclk values or enabling new platforms.  Let's just add a form of the
bspec table to the code and then adjust our functions to pull what they
need directly out of the table.

v2: Fix comparison when finding best cdclk.

v3: Another logic fix for calc_cdclk.

v4:
 - Use named initializers for cdclk tables. (Ville)
 - Include refclk as a field in the table instead of adding all three
   ratios for each entry. (Ville)
 - Terminate tables with an empty entry to avoid needing to store the
   table size. (Ville)
 - Don't try so hard to return reasonable values from our lookup
   functions if we get impossible inputs; just WARN and return 0.
   (Ville)
 - Keep a bxt_ prefix on the lookup functions since they're still only
   used on bxt+ for now.  We can rename them later if we extend this
   table-based approach back to older platforms.  (Ville)

v5:
 - Fix cnl table's ratios for 24mhz refclk. (Ville)
 - Don't miss the named initializers on the cnl table. (Ville)
 - Represent refclk in table as u16 rather than u32. (Ville)

07e98eb0a1 drm/i915/selftests: Tighten the timeout testing for partial mmaps
Currently, if there is time remaining before the start of the loop, we
do one full iteration over many possible different chunks within the
object. A full loop may take 50+s (depending on speed of indirect GTT
mmapings) and we try separately with LINEAR, X and Y -- at which point
igt times out. If we check more frequently, we will interrupt the loop
upon our timeout -- it is hard to argue for as this significantly reduces
the test coverage as we dramatically reduce the runtime. In practical
terms, the coverage we should prioritise is in using different fence
setups, forcing verification of the tile row computations over the
current preference of checking extracting chunks. Though the exhaustive
search is great given an infinite timeout, to improve our current
coverage, we also add a randomised smoketest of partial mmaps. So let's
do both, add a randomised smoketest of partial tiling chunks and the
exhaustive (though time limited) search for failures.

Even in adding another subtest, we should shave 100s off BAT! (With,
hopefully, no loss in coverage, at least over multiple runs.)

fa9a09f150 drm/i915/execlists: Clear STOP_RING bit on reset
During reset, we try to ensure no forward progress of the CS prior to
the reset by setting the STOP_RING bit in RING_MI_MODE. Since gen9, this
register is context saved and do we end up in the odd situation where we
save the STOP_RING bit and so try to stop the engine again immediately
upon resume. This is quite unexpected and causes us to complain about an
early CS completion event!

This bit was fliped on for "syncing dependencies between camera and

unrecoverable GPU hangs with Vulkan compute workloads.

From BSpec, setting bit5 to 0 enables relaxed padding requirements for
buffers, 1D and 2D non-array, non-MSAA, non-mip-mapped linear surfaces;
and *must* be set to 0h on skl+ to ensure "Out of Bounds" case is
suppressed.

bb1a71f9c4 drm/i915: Limit MST to <= 8bpc once again
My attempt at allowing MST to use the higher color depths has
regressed some configurations. Apparently people have setups
where all MST streams will fit into the DP link with 8bpc but
won't fit with higher color depths.

What we really should be doing is reducing the bpc for all the
streams on the same link until they start to fit. But that requires
a bit more work, so in the meantime let's revert back closer to
the old behavior and limit MST to at most 8bpc.

37a48adfba drm/vram: Add kmap ref-counting to GEM VRAM objects
The kmap and kunmap operations of GEM VRAM buffers can now be called
in interleaving pairs. The first call to drm_gem_vram_kmap() maps the
buffer's memory to kernel address space and the final call to
drm_gem_vram_kunmap() unmaps the memory. Intermediate calls to these
functions increment or decrement a reference counter.

This change allows for keeping buffer memory mapped for longer and
minimizes the amount of changes to TLB, page tables, etc.

d810583fc2 drm/i915/execlists: Remove incorrect BUG_ON for schedule-out
As we may unwind incomplete requests (for preemption) prior to
processing the CSB and the schedule-out events, we may update rq->engine
(resetting it to point back to the parent virtual engine) prior to
calling execlists_schedule_out(), invalidating the assertion that the
request still points to the inflight engine. (The likelihood of this is
increased if the CSB interrupt processing is pushed to the ksoftirqd for
being too slow and direct submission overtakes it.)

Tvrtko summarised it as:
"So unwind from direct submission resets rq->engine and races with
process_csb from the tasklet which notices request has actually
completed."

92a57b3fb5 drm/stm: ltdc: add pinctrl for DPI encoder mode
The implementation of functions encoder_enable and encoder_disable
make possible to control the pinctrl according to the encoder type.
The pinctrl must be activated only if the encoder type is DPI.
This helps to move the DPI-related pinctrl configuration from
all the panel or bridge to the LTDC dt node.

89958b7cd9 drm/bridge: panel: Infer connector type from panel by default
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.

The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection and fixes to indentation.

@@
expression bridge;
expression dev;
expression panel;
identifier type;

(
-bridge = drm_panel_bridge_add(panel, type);

eDP, DSI and DPI). This will be used to initialise the corresponding

Update all panel drivers accordingly. The panel-simple driver only
specifies the type for the known to be LVDS panels, while all other

Daniele pointed out that relative mmio works differently in

it masks out the base and adds bits [12:2] to current engine base.

This should allow us to construct context register state to be
applicable to all instances, including virtual. And avoid the trouble
of updating the registers on virtual instances when submitting work.

9e77f5001b drm/i915: to make vgpu ppgtt notificaiton as atomic operation
vgpu ppgtt notification was split into 2 steps, the first step is to
update PVINFO's pdp register and then write PVINFO's g2v_notify register
with action code to tirgger ppgtt notification to GVT side.

currently these steps were not atomic operations due to no any protection,
so it is easy to enter race condition state during the MTBF, stress and
IGT test to cause GPU hang.

the solution is to add a lock to make vgpu ppgtt notication as atomic
operation.

c7581a414d drm: Use EOPNOTSUPP, not ENOTSUPP
- it's what we recommend in our docs:

https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#recommended-ioctl-return-values

- it's the overwhelmingly used error code for "operation not
  supported", at least in drm core (slightly less so in drivers):

$ git grep EOPNOTSUPP -- drivers/gpu/drm/*c | wc -l
83
$ git grep ENOTSUPP -- drivers/gpu/drm/*c | wc -l
5

- include/linux/errno.h makes it fairly clear that these are for nfsv3
  (plus they also have error codes above 512, which is the block with
  some special behaviour ...)

/* Defined for the NFSv3 protocol */

If the above isn't reflecting current practice, then I guess we should
at least update the docs.

Noralf commented:

Ben Hutchings made this comment[1] in a thread about use of ENOTSUPP in
drivers:

  glibc's strerror() returns these strings for ENOTSUPP and EOPNOTSUPP
  respectively:

  "Unknown error 524"
  "Operation not supported"

So at least for errors returned to userspace EOPNOTSUPP makes sense.

José asked:

> Hopefully this will not break any userspace

None of the functions in drm_edid.c affected by this reach userspace,
it's all driver internal.

Same for the mipi function, that error code should be handled by
drivers. Drivers are supposed to remap "the hw is on fire" to EIO when
reporting up to userspace, but I think if a driver sees this it would
be a driver bug.
v2: Augment commit message with comments from Noralf and José

aaef851083 drm/i915/mst: Do not hardcoded the crtcs that encoder can connect
Tiger Lake has up to 4 pipes so the mask would need to be 0xf instead of
0x7. Do not hardcode the mask so it allows the fake MST encoders to

Iterating over all pipes to keep consistent with intel_ddi_init().

Initialy this patch was replaced by commit 4eaceea3a0 ("drm/i915:

08b0c89160 drm/vmwgfx: Fix double free in vmw_recv_msg()
We recently added a kfree() after the end of the loop:

	if (retries == RETRIES) {
		kfree(reply);
		return -EINVAL;
	}

There are two problems.  First the test is wrong and because retries
equals RETRIES if we succeed on the last iteration through the loop.
Second if we fail on the last iteration through the loop then the kfree
is a double free.

When you're reading this code, please note the break statement at the
end of the while loop.  This patch changes the loop so that if it's not
successful then "reply" is NULL and we can test for that afterward.

4444df6e20 drm/i915/tgl: move DP_TP_* to transcoder
Gen 12 onwards moves the DP_TP_* registers to be transcoder-based rather
than port-based. This adds the new register addresses and changes all
the callers to use the register saved in intel_dp->regs.*. This is
filled out when preparing to enable the port so we take into account if
we should use the transcoder or the port.

v2: reimplement by stashing the registers we want to access under
intel_dp->reg. Now they are initialized when enabling the port.
Ville suggested to store the transcoder to be used exclusively
by TGL+. After implementing I thought just storing the register directly
made it cleaner.

8241cfbe67 drm/i915/tgl: Access the right register when handling PSR interruptions
For older gens PSR IIR and IMR have fixed addresses. From TGL onwards those
registers moved to each transcoder offset. The bits for the registers
are defined without an offset per transcoder as right now we have one
register per transcoder. So add a fake "trans_shift" when calculating
the bits offsets: it will be 0 for gen12+ and psr.transcoder otherwise.

getting each bit value with a different macro

2f3b87124b drm/i915/psr: Only handle interruptions of the transcoder in use
It was enabling and checking PSR interruptions in every transcoder
while it should keep the interruptions on the non-used transcoders
masked.

While doing this it gives us trouble on Tiger Lake if we are
reading/writing to registers of disabled transcoders since from gen12
onwards the registers are relative to the transcoder. Instead of forcing
them ON to access those registers, just avoid the accesses as they are
not needed.

v2 (Lucas):
  - Explain why we can't keep accessing all transcoders
  - Remove TODO about extending the irq handling to multiple instances:
    when/if implementing multiple instances it's pretty clear by the
    singleton psr that it needs to be extended
  - Fix intel_psr_debug_set() calling psr_irq_control() with
    psr.transcoder not set yet (from Imre). Now we only set the debug
    register right away if psr is already enabled. Otherwise we just
    record the value to be set when enabling the source.
  - Do not depend on the value of TRANSCODER_A. Just be relative to it
    (from Imre)
  - handle psr error last so we don't schedule the work before handling
    the other flags

v3:
  - Adding a warning about setting reserverd bits on EDP_PSR_IMR

ab01691498 drm/i915: disable set/get_tiling ioctl on gen12+
The cpu (de)tiler hw is gone, this stopped being useful. Plus it never
supported any of the fancy new tiling formats, which means userspace
also stopped using the magic side-channel this provides.

This would totally break a lot of the igts, but they're already broken
for the same reasons as userspace on gen12 would be.

v2: Look at ggtt->num_fences instead, that also avoids the need for a
comment (Chris). This also means that gen12 support really needs to
make sure num_fences is set to 0. There is a patch for that, but it
checks for HAS_MAPPABLE_APERTURE, which I'm not sure is the right
thing really. Adding relevant people.

e838bfa8e1 Revert "drm/i915: Fix DP-MST crtc_mask"
This reverts commit 4eaceea3a0.

Several userspace clients (modesetting ddx and mutter+wayland at least)
handle encoder.possible_crtcs incorrectly. What they essentially do is
the following:

possible_crtcs = ~0;
for_each_possible_encoder(connector)
	possible_crtcs &= encoder->possible_crtcs;

Ie. they calculate the intersection of the possible_crtcs
for the connector when they really should be calculating the
union instead.

In our case each MST encoder now has just one unique bit set,
and so the intersection is always zero. The end result is that
MST connectors can't be lit up because no crtc can be found to
drive them.

I've submitted a fix for the modesetting ddx [1], and complained
on #wayland about mutter, so hopefully the situation will improve
in the future. In the meantime we have regression, and so must go
back to the old way of misconfiguring possible_crtcs in the kernel.

54b8ae66ae kbuild: change *FLAGS_<basetarget>.o to take the path relative to $(obj)
Kbuild provides per-file compiler flag addition/removal:

  CFLAGS_<basetarget>.o
  CFLAGS_REMOVE_<basetarget>.o
  AFLAGS_<basetarget>.o
  AFLAGS_REMOVE_<basetarget>.o
  CPPFLAGS_<basetarget>.lds
  HOSTCFLAGS_<basetarget>.o
  HOSTCXXFLAGS_<basetarget>.o

The <basetarget> is the filename of the target with its directory and
suffix stripped.

This syntax comes into a trouble when two files with the same basename
appear in one Makefile, for example:

  obj-y += foo.o
  obj-y += dir/foo.o
  CFLAGS_foo.o := <some-flags>

Here, the <some-flags> applies to both foo.o and dir/foo.o

The real world problem is:

  scripts/kconfig/util.c
  scripts/kconfig/lxdialog/util.c

Both files are compiled into scripts/kconfig/mconf, but only the
latter should be given with the ncurses flags.

It is more sensible to use the relative path to the Makefile, like this:

  obj-y += foo.o
  CFLAGS_foo.o := <some-flags>
  obj-y += dir/foo.o
  CFLAGS_dir/foo.o := <other-flags>

At first, I attempted to replace $(basetarget) with $*. The $* variable
is replaced with the stem ('%') part in a pattern rule. This works with
most of cases, but does not for explicit rules.

For example, arch/ia64/lib/Makefile reuses rule_as_o_S in its own
explicit rules, so $* will be empty, resulting in ignoring the per-file
AFLAGS.

I introduced a new variable, target-stem, which can be used also from
explicit rules.

This bit was fliped on for "syncing dependencies between camera and

unrecoverable GPU hangs with Vulkan compute workloads.

From BSpec, setting bit5 to 0 enables relaxed padding requirements for

and *must* be set to 0h on skl+ to ensure "Out of Bounds" case is

so remove the third way of doing things.

145450f6a4 drm/i915/display: Add func to get gamma bit precision
Each platform supports different gamma modes and each gamma mode
has different bit precision. Here bit precision corresponds
to number of bits the hw LUT supports.

Add func per platform to return bit precision corresponding to gamma mode
which will be later used as a parameter in lut comparison function
intel_color_lut_equal().

This is done for legacy, ilk, glk and their variant platforms.

v6:  -Added func intel_color_get_bit_precision() to get bit precision for
      gamma and degamma lut readout depending upon platform and
      corresponding to load_luts() [Ankit]
     -Made patch11 as patch3 [Jani]
v7:  -Renamed func intel_color_get_bit_precision() to
      intel_color_get_gamma_bit_precision()
     -Added separate function/platform for gamma bit precision [Ville]
     -Corrected checkpatch warnings
v8:  -Split patch 3 into 4 separate patches
v9:  -Changed commit message, gave more info [Uma]
     -Added precision func for icl+ platform
v10: -Removed precision func for chv and icl+ platforms [Jani]
     -Added gamma_enable check once [Jani]

f0c6cef7e7 drm/virtio: add worker for object release
Move object release into a separate worker.  Releasing objects requires
sending commands to the host.  Doing that in the dequeue worker will
cause deadlocks in case the command queue gets filled up, because the
dequeue worker is also the one which will free up slots in the command
queue.
