5f97816762 drm/i915: Introduce new macros for i915 PTE
Certain functions within i915 uses macros that are defined for
specific architectures by the mmu, such as _PAGE_RW and _PAGE_PRESENT
(Some architectures don't even have these macros defined, like ARM64).

Instead of re-using bits defined for the CPU, we should use bits
defined for i915. This patch introduces two new 64 bit macros,
GEN8_PAGE_PRESENT and GEN8_PAGE_RW, to check for bits 0 and 1 and, to
replace all occurrences of _PAGE_RW and _PAGE_PRESENT within i915.

v2(Michael Cheng): Use GEN8_ instead of I915_

2027e5b341 drm/msm: Initialize MDSS irq domain at probe time
Since commit 8f59ee9a57 ("drm/msm/dsi: Adjust probe order"), the
DSI host gets initialized earlier, but this caused unability to probe
the entire stack of components because they all depend on interrupts
coming from the main `mdss` node (mdp5, or dpu1).

To fix this issue, move mdss device initialization (which include irq
domain setup) to msm_mdev_probe() time, as to make sure that the
interrupt controller is available before dsi and/or other components try
to initialize, finally satisfying the dependency.

ec919e6e71 drm/msm: Allocate msm_drm_private early and pass it as driver data
In preparation for registering the mdss interrupt controller earlier,
move the allocation of msm_drm_private from component bind time to
msm_drv probe; this also allows us to use the devm variant of kzalloc.

Since it is not right to allocate the drm_device at probe time (as
it should exist only when all components are bound, and taken down
when components get cleaned up), the only way to make this happen is
to pass a pointer to msm_drm_private as driver data (like done in
many other DRM drivers), instead of one to drm_device like it's
currently done in this driver.

This is also simplifying some bind/unbind functions around drm/msm,
as some of them are using drm_device just to grab a pointer to the
msm_drm_private structure, which we now retrieve in one call.

On platforms with an external clock, both the group and crtc must be
handled accordingly to correctly pass through the external clock and
configure the DU to use the external rate.

The CRTC support was missed while adding the DSI support on the r8a779a0
which led to the output clocks being incorrectly determined.

Ensure that when a CRTC is routed through the DSI encoder, the external
clock is used without any further divider being applied.

42d95d1b3a drm/rcar: stop using 'imply' for dependencies
The meaning of the 'imply' keyword has changed recently, and neither the
old meaning (select the symbol if its dependencies are met) nor the new
meaning (enable it by default, but let the user set any other setting)
is what we want here.

Work around this by adding two more Kconfig options that lead to
the correct behavior: if DRM_RCAR_USE_CMM and DRM_RCAR_USE_LVDS
are enabled, that portion of the driver becomes usable, and no
configuration results in a link error.

This avoids a link failure:

32024bb85e drm/i915/fbc: Pass i915 instead of FBC instance to FBC underrun stuff
The underrun code doesn't need to know any details about FBC, so
just pass in the whole device rather than a specific FBC instance.
We could make this a bit more fine grained by also passing in the
pipe to intel_fbc_handle_fifo_underrun_irq() and letting the FBC
code figure which FBC instance (if any) is active on said pipe.
But that seems a bit overkill for this so don't bother.

2e6c99f886 drm/i915/fbc: Nuke lots of crap from intel_fbc_state_cache
There's no need to store all this stuff in intel_fbc_state_cache.
Just check it all against the plane/crtc states and store only
what we need. Probably more should get nuked still, but this
is a start.

So what we'll do is:
- each plane will check its own state and update its local
  no_fbc_reason
- the per-plane no_fbc_reason (if any) then gets propagated
  to the cache->no_fbc_reason while doing the actual update
- fbc->no_fbc_reason gets updated in the end with either
  the value from the cache or directly from frontbuffer
  tracking

It's still a bit messy, but should hopefuly get cleaned up
more in the future. At least now we can observe each plane's
reasons for rejecting FBC now more consistently, and we don't
have so mcuh redundant state store all over the place.

f84b336a2f drm/i915: Get rid of the 64bit PLANE_CC_VAL mmio
Let's just stick to 32bit mmio accesses so we can get rid
of the bare "uncore" reg access in display code. The register
are defined as 32bit in the spec anyway.

We could define a 64bit "de" variant I suppose, but doesn't
really make much sense just for this one case, and when we
start to use the DSB for this stuff we'd also need another
64bit variant for that. Just easier to do 32bit always.

While at it we can reorder stuff a bit so that we write the
registers in order of increasing offset (more or less).

vm->ib_bo_va and passes and used in radeon_vm_bo_set_addr(). In
radeon_vm_bo_set_addr(), there is a dereference of vm->ib_bo_va,
which could lead to a NULL pointer dereference on failure of
radeon_vm_bo_add().

Fix this bug by adding a check of vm->ib_bo_va.

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_DRM_RADEON=m show no new warnings,
and our static analyzer no longer warns about this code.

69cb56290d drm/amd/display: Use oriented source size when checking cursor scaling
dm_check_crtc_cursor() doesn't take into account plane transforms when
calculating plane scaling, this can result in false positives.

For example, if there's an output with resolution 3840x2160 and the
output is rotated 90 degrees, CRTC_W and CRTC_H will be 3840 and 2160,
respectively, but SRC_W and SRC_H will be 2160 and 3840, respectively.

Since the cursor plane usually has a square buffer attached to it, the
dm_check_crtc_cursor() will think that there's a scale factor mismatch
even though there isn't really.

This fixes an issue where kwin fails to use hardware plane transforms.

Changes since version 1:
- s/orientated/oriented/g

PLANE_SIZE and scaler size registers supports max 5120.
Take care of this restriction in max_width.

Without this patch, when 5k content is sent on HDR plane

4ff22f487f drm: Return error codes from struct drm_driver.gem_create_object
GEM helper libraries use struct drm_driver.gem_create_object to let
drivers override GEM object allocation. On failure, the call returns
NULL.

Change the semantics to make the calls return a pointer-encoded error.
This aligns the callback with its callers. Fixes the ingenic driver,
which already returns an error pointer.

Also update the callers to handle the involved types more strictly.

2da34b7bb5 drm/amd/display: add connector type check for CRC source set
[Why]
IGT bypass test will set crc source as DPRX,and display DM didn`t check
connection type, it run the test on the HDMI connector ,then the kernel
will be crashed because aux->transfer is set null for HDMI connection.
This patch will skip the invalid connection test and fix kernel crash issue.

[How]
Check the connector type while setting the pipe crc source as DPRX or
auto,if the type is not DP or eDP, the crtc crc source will not be set
and report error code to IGT test,IGT will show the this subtest as no
valid crtc/connector combinations found.

94ebc03545 drm/amd/display: Allow DSC on supported MST branch devices
[Why]
When trying to lightup two 4k60 non-DSC displays behind a branch device
that supports DSC we can't lightup both at once due to bandwidth
limitations - each requires 48 VCPI slots but we only have 63.

[How]
The workaround already exists in the code but is guarded by a CONFIG
that cannot be set by the user and shouldn't need to be.

Check for specific branch device IDs to device whether to enable
the workaround for multiple display scenarios.

405af9793f drm/amd/display: add connector type check for CRC source set
[Why]
IGT bypass test will set crc source as DPRX,and display DM didn`t check
connection type, it run the test on the HDMI connector ,then the kernel
will be crashed because aux->transfer is set null for HDMI connection.
This patch will skip the invalid connection test and fix kernel crash issue.

[How]
Check the connector type while setting the pipe crc source as DPRX or
auto,if the type is not DP or eDP, the crtc crc source will not be set
and report error code to IGT test,IGT will show the this subtest as no
valid crtc/connector combinations found.

During otg sync trigger, plane states are used to decide whether the otg

excluded from synchronization.

[How]
Introduced pipe_idx_syncd in pipe_ctx that tracks each otgs master pipe.
When a otg is disabled/enabled, pipe_idx_syncd is reset to itself.
On sync trigger, pipe_idx_syncd is checked to decide whether a otg is
already synchronized and the otg is further included or excluded from
synchronization.

Without this delay the user experience is impacted since it can take

Only allow vblank disable immediate for DC when psr is not supported.

Leave a TODO indicating that this support should be extended in the

f6be23264b drm/vmwgfx: Introduce a new placement for MOB page tables
For larger (bigger than a page) and noncontiguous mobs we have
to create page tables that allow the host to find the memory.
Those page tables just used regular system memory. Unfortunately
in TTM those BO's are not allowed to be busy thus can't be
fenced and we have to fence those bo's  because we don't want
to destroy the page tables while the host is still executing
the command buffers which might be accessing them.

To solve it we introduce a new placement VMW_PL_SYSTEM which
is very similar to TTM_PL_SYSTEM except that it allows
fencing. This fixes kernel oops'es during unloading of the driver
(and pci hot remove/add) which were caused by busy BO's in
TTM_PL_SYSTEM being present in the delayed deletion list in
TTM (TTM_PL_SYSTEM manager is destroyed before the delayed
deletions are executed)

ff20afc4ce drm/i915: Update error capture code to avoid using the current vma state
With asynchronous migrations, the vma state may be several migrations
ahead of the state that matches the request we're capturing.
Address that by introducing an i915_vma_snapshot structure that
can be used to snapshot relevant state at request submission.
In order to make sure we access the correct memory, the snapshots take
references on relevant sg-tables and memory regions.

Also move the capture list allocation out of the fence signaling
critical path and use the CONFIG_DRM_I915_CAPTURE_ERROR define to
avoid compiling in members and functions used for error capture
when they're not used.

Finally, Introduce lockdep annotation.

v4:
- Break out the capture allocation mode change to a separate patch.
v5:
- Fix compilation error in the !CONFIG_DRM_I915_CAPTURE_ERROR case
  (kernel test robot)
v6:
- Use #if IS_ENABLED() instead of #ifdef to match driver style.
- Move yet another change of allocation mode to the separate patch.
- Commit message rework due to patch reordering.

a44f42ba7f drm/i915/dp: Perform 30ms delay after source OUI write
While working on supporting the Intel HDR backlight interface, I noticed
that there's a couple of laptops that will very rarely manage to boot up
without detecting Intel HDR backlight support - even though it's supported
on the system. One example of such a laptop is the Lenovo P17 1st
generation.

Following some investigation Ville Syrjälä did through the docs they have
available to them, they discovered that there's actually supposed to be a
30ms wait after writing the source OUI before we begin setting up the rest
of the backlight interface.

This seems to be correct, as adding this 30ms delay seems to have
completely fixed the probing issues I was previously seeing. So - let's
start performing a 30ms wait after writing the OUI, which we do in a manner
similar to how we keep track of PPS delays (e.g. record the timestamp of
the OUI write, and then wait for however many ms are left since that
timestamp right before we interact with the backlight) in order to avoid
waiting any longer then we need to. As well, this also avoids us performing
this delay on systems where we don't end up using the HDR backlight
interface.

V3:
* Move last_oui_write into intel_dp
V2:
* Move panel delays into intel_pps

f5be833dc8 drm/etnaviv: use a 32 bit mask as coherent DMA mask
The STLB and the first command buffer (which is used to set up the TLBs)
has a 32 bit size restriction in hardware. There seems to be no way to
specify addresses larger than 32 bit. Keep it simple and restict the
addresses to the lower 4 GiB range for all coherent DMA memory
allocations.

Please note, that platform_device_alloc() will initialize dev->dma_mask
to point to pdev->platform_dma_mask, thus dma_set_mask() will work as
expected.

While at it, move the dma_mask setup code to the of_dma_configure() to
keep all the DMA setup code next to each other.

device_add() via the platform bus:
  device_add()
    blocking_notifier_call_chain()
      iommu_bus_notifier()
        iommu_probe_device()
          __iommu_probe_device()
            iommu_group_get_for_dev()
              iommu_group_add_device()

Move of_dma_configure() into the probe function, which is called after
device_add(). Normally, the platform code will already call it itself
if .of_node is set. Unfortunately, this isn't the case here.

49a8bf50ca drm/i915/gem: Fix a NULL pointer dereference in igt_request_rewind()
In igt_request_rewind(), mock_context(i915, "A") is assigned to ctx[0]
and used in i915_gem_context_get_engine(). There is a dereference
of ctx[0] in i915_gem_context_get_engine(), which could lead to a NULL
pointer dereference on failure of mock_context(i915, "A") .

So as mock_context(i915, "B").

Although this bug is not serious for it belongs to testing code, it is
better to be fixed to avoid unexpected failure in testing.

Fix this bugs by adding checks about ctx[0] and ctx[1].

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_DRM_I915_SELFTEST=y show no new warnings,
and our static analyzer no longer warns about this code.

cca0846923 drm/i915: Use per device iommu check
With both integrated and discrete Intel GPUs in a system, the current
global check of intel_iommu_gfx_mapped, as done from intel_vtd_active()
may not be completely accurate.

In this patch we add i915 parameter to intel_vtd_active() in order to
prepare it for multiple GPUs and we also change the check away from Intel
specific intel_iommu_gfx_mapped (global exported by the Intel IOMMU
driver) to probing the presence of IOMMU on a specific device using
device_iommu_mapped().

This will return true both for IOMMU pass-through and address translation
modes which matches the current behaviour. If in the future we wanted to
distinguish between these two modes we could either use
iommu_get_domain_for_dev() and check for __IOMMU_DOMAIN_PAGING bit
indicating address translation, or ask for a new API to be exported from
the IOMMU core code.

v2:
  * Check for dmar translation specifically, not just iommu domain. (Baolu)

v3:
 * Go back to plain "any domain" check for now, rewrite commit message.

v4:
 * Use device_iommu_mapped. (Robin, Baolu)

c7c90b0b84 drm/i915/dp: Perform 30ms delay after source OUI write
While working on supporting the Intel HDR backlight interface, I noticed
that there's a couple of laptops that will very rarely manage to boot up
without detecting Intel HDR backlight support - even though it's supported
on the system. One example of such a laptop is the Lenovo P17 1st
generation.

Following some investigation Ville Syrjälä did through the docs they have
available to them, they discovered that there's actually supposed to be a
30ms wait after writing the source OUI before we begin setting up the rest
of the backlight interface.

This seems to be correct, as adding this 30ms delay seems to have
completely fixed the probing issues I was previously seeing. So - let's
start performing a 30ms wait after writing the OUI, which we do in a manner
similar to how we keep track of PPS delays (e.g. record the timestamp of
the OUI write, and then wait for however many ms are left since that
timestamp right before we interact with the backlight) in order to avoid
waiting any longer then we need to. As well, this also avoids us performing
this delay on systems where we don't end up using the HDR backlight
interface.

V3:
* Move last_oui_write into intel_dp
V2:
* Move panel delays into intel_pps

2a67b18e67 drm/i915/pmu: Fix synchronization of PMU callback with reset
Since the PMU callback runs in irq context, it synchronizes with gt
reset using the reset count. We could run into a case where the PMU
callback could read the reset count before it is updated. This has a
potential of corrupting the busyness stats.

In addition to the reset count, check if the reset bit is set before
capturing busyness.

In addition save the previous stats only if you intend to update them.

v2:
- The 2 reset counts captured in the PMU callback can end up being the
  same if they were captured right after the count is incremented in the
  reset flow. This can lead to a bad busyness state. Ensure that reset
  is not in progress when the initial reset count is captured.

drm/vc4: kms: Fix previous HVS commit wait
Our current code is supposed to serialise the commits by waiting for all
the drm_crtc_commits associated to the previous HVS state.

However, assuming we have two CRTCs running and being configured and we
configure each one alternately, we end up in a situation where we're
not waiting at all.

Indeed, starting with a state (state 0) where both CRTCs are running,
and doing a commit (state 1) on the first CRTC (CRTC 0), we'll associate
its commit to its assigned FIFO in vc4_hvs_state.

If we get a new commit (state 2), this time affecting the second CRTC
(CRTC 1), the DRM core will allow both commits to execute in parallel
(assuming they don't have any share resources).

Our code in vc4_atomic_commit_tail is supposed to make sure we only get
one commit at a time and serialised by order of submission. It does so
by using for_each_old_crtc_in_state, making sure that the CRTC has a
FIFO assigned, is used, and has a commit pending. If it does, then we'll
wait for the commit before going forward.

During the transition from state 0 to state 1, as our old CRTC state we
get the CRTC 0 state 0, its commit, we wait for it, everything works fine.

During the transition from state 1 to state 2 though, the use of
for_each_old_crtc_in_state is wrong. Indeed, while the code assumes it's
returning the state of the CRTC in the old state (so CRTC 0 state 1), it
actually returns the old state of the CRTC affected by the current
commit, so CRTC 0 state 0 since it wasn't part of state 1.

Due to this, if we alternate between the configuration of CRTC 0 and
CRTC 1, we never actually wait for anything since we should be waiting
on the other every time, but it never is affected by the previous
commit.

Change the logic to, at every commit, look at every FIFO in the previous
HVS state, and if it's in use and has a commit associated to it, wait
for that commit.

drm/vc4: kms: Don't duplicate pending commit
Our HVS global state, when duplicated, will also copy the pointer to the
drm_crtc_commit (and increase the reference count) for each FIFO if the
pointer is not NULL.

However, our atomic_setup function will overwrite that pointer without
putting the reference back leading to a memory leak.

Since the commit is only relevant during the atomic commit process, it
doesn't make sense to duplicate the reference to the commit anyway.
Let's remove it.

drm/vc4: kms: Clear the HVS FIFO commit pointer once done
Commit 9ec03d7f1e ("drm/vc4: kms: Wait on previous FIFO users before a
commit") introduced a wait on the previous commit done on a given HVS
FIFO.

However, we never cleared that pointer once done. Since
drm_crtc_commit_put can free the drm_crtc_commit structure directly if
we were the last user, this means that it can lead to a use-after free
if we were to duplicate the state, and that stale pointer would even be
copied to the new state.

Set the pointer to NULL once we're done with the wait so that we don't
carry over a pointer to a free'd structure.

drm/vc4: kms: Add missing drm_crtc_commit_put
Commit 9ec03d7f1e ("drm/vc4: kms: Wait on previous FIFO users before a

the current CRTC commit so that we can properly synchronize commits.

However, the refcounting was off and we thus ended up leaking the
drm_crtc_commit structure every commit. Add a drm_crtc_commit_put to
prevent the leakage.

drm/vc4: kms: Wait for the commit before increasing our clock rate
Several DRM/KMS atomic commits can run in parallel if they affect
different CRTC. These commits share the global HVS state, so we have
some code to make sure we run commits in sequence. This synchronization
code is one of the first thing that runs in vc4_atomic_commit_tail().

Another constraints we have is that we need to make sure the HVS clock
gets a boost during the commit. That code relies on clk_set_min_rate and
will remove the old minimum and set a new one. We also need another,
temporary, minimum for the duration of the commit.

The algorithm is thus to set a temporary minimum, drop the previous
one, do the commit, and finally set the minimum for the current mode.

However, the part that sets the temporary minimum and drops the older
one runs before the commit synchronization code.

Thus, under the proper conditions, we can end up mixing up the minimums
and ending up with the wrong one for our current step.

To avoid it, let's move the clock setup in the protected section.

This is because paravirtualized userspaces receives responses in a

To be in line with other DRM drivers and avoid specialized behavior,
it is possible to define a dummy event for virtgpu.  Paravirtualized
userspace will now have to call read(..) on the DRM fd to receive the
dummy event.

Re-work the boost and idle clamping to use PM QoS requests instead, so

This does have the minor side-effect that devfreq sysfs min_freq/
max_freq files now reflect the boost and idle clamping, as they show
(despite what they are documented to show) the aggregated min/max freq.
Fixing that in devfreq does not look straightforward after considering
that OPPs can be dynamically added/removed.  However writes to the

drm: Fix build error caused by missing drm_nomodeset.o
The patch for commit 6a2d2ddf2c ("drm: Move nomodeset kernel parameter
to the DRM subsystem") was generated with config 'diff.noprefix true'.

But later was applied using 'cat nomodeset.mbox | dim apply-branch' on a
machine with 'diff.noprefix false'. And command 'git am --scissors -3' as
used by the dim tool doesn't handle that case well, since the 3-way merge
wrongly resolves the path for new file drivers/gpu/drm/drm_nomodeset.c as
gpu/drm/drm_nomodeset.c instead.

It led to the following build error as reported by the kernel test robot:

  make[4]: *** No rule to make target 'drivers/gpu/drm/drm_nomodeset.o', needed by 'drivers/gpu/drm/built-in.a'.

drm: Move nomodeset kernel parameter to the DRM subsystem
The "nomodeset" kernel cmdline parameter is handled by the vgacon driver
but the exported vgacon_text_force() symbol is only used by DRM drivers.

It makes much more sense for the parameter logic to be in the subsystem
of the drivers that are making use of it.

Let's move the vgacon_text_force() function and related logic to the DRM
subsystem. While doing that, rename it to drm_firmware_drivers_only() and
make it return true if "nomodeset" was used and false otherwise. This is
a better description of the condition that the drivers are testing for.

afece15a68 drm: msm: fix building without CONFIG_COMMON_CLK
When CONFIG_COMMON_CLOCK is disabled, the 8996 specific
phy code is left out, which results in a link failure:

ld: drivers/gpu/drm/msm/hdmi/hdmi_phy.o:(.rodata+0x3f0): undefined reference to `msm_hdmi_phy_8996_cfg'

This was only exposed after it became possible to build
test the driver without the clock interfaces.

Make COMMON_CLK a hard dependency for compile testing,
and simplify it a little based on that.

8b91cdd4f8 drm/i915: Use __GFP_KSWAPD_RECLAIM in the capture code
The capture code is typically run entirely in the fence signalling
critical path. We're about to add lockdep annotation in an upcoming patch
which reveals a lockdep splat similar to the below one.

Fix the associated potential deadlocks using __GFP_KSWAPD_RECLAIM
(which is the same as GFP_WAIT, but open-coded for clarity) rather than
GFP_KERNEL for memory allocation in the capture path. This has the
potential drawback that capture might fail in situations with memory
pressure.

e45b98ba62 drm/i915: Avoid allocating a page array for the gpu coredump
The gpu coredump typically takes place in a dma_fence signalling
critical path, and hence can't use GFP_KERNEL allocations, as that
means we might hit deadlocks under memory pressure. However
changing to __GFP_KSWAPD_RECLAIM which will be done in an upcoming
patch will instead mean a lower chance of the allocation succeeding.
In particular large contigous allocations like the coredump page
vector.
Remove the page vector in favor of a linked list of single pages.
Use the page lru list head as the list link, as the page owner is
allowed to do that.

5c2625c4a0 drm/i915: Remove dma_resv_prune
The signaled bit is already used for quick testing if a fence is signaled.
On top of that, it's a terrible abuse of dma-fence api, and in the common
case where the object is already locked by the caller, the trylock will fail.

If it were useful, the core dma-api would have exposed the same functionality.

The fact that i915 has a dma_resv_utils.c file should be a warning that the
functionality either belongs in core, or is not very useful at all.
In this case the latter.

Maarten requested a backmerge due his work depending on subtle semantic
changes introduced by:

  7e2e69ed46 ("drm/i915: Fix i915_request fence wait semantics")
  2cbb8d4d67 ("drm/i915: use new iterator in i915_gem_object_wait_reservation")

Both should probably have been merged to drm-intel-gt-next anyway.

drm/bridge: megachips: Ensure both bridges are probed before registration
In the configuration used by the b850v3, the STDP2690 is used to read EDID
data whilst it's the STDP4028 which can detect when monitors are connected.

This can result in problems at boot with monitors connected when the
STDP4028 is probed first, a monitor is detected and an attempt is made to
read the EDID data before the STDP2690 has probed:

6385eb7ad8 drm/i915/ttm: Implement asynchronous TTM moves
Don't wait sync while migrating, but rather make the GPU blit await the
dependencies and add a moving fence to the object.

This also enables asynchronous VRAM management in that on eviction,
rather than waiting for the moving fence to expire before freeing VRAM,
it is freed immediately and the fence is stored with the VRAM manager and
handed out to newly allocated objects to await before clears and swapins,
or for kernel objects before setting up gpu vmas or mapping.

To collect dependencies before migrating, add a set of utilities that
coalesce these to a single dma_fence.

What is still missing for fully asynchronous operation is asynchronous vma
unbinding, which is still to be implemented.

This commit substantially reduces execution time in the gem_lmem_swapping
test.

v2:
- Make a couple of functions static.
v4:
- Fix some style issues (Matthew Auld)

004746e4b1 drm/i915/ttm: Correctly handle waiting for gpu when shrinking
With async migration, the shrinker may end up wanting to release the
pages of an object while the migration blit is still running, since
the GT migration code doesn't set up VMAs and the shrinker is thus
oblivious to the fact that the GPU is still using the pages.

Add waiting for gpu in the shrinker_release_pages() op and an
argument to that function indicating whether the shrinker expects it
to not wait for gpu. In the latter case the shrinker_release_pages()
op will return -EBUSY if the object is not idle.

f6c466b84c drm/i915: Add support for moving fence waiting
For now, we will only allow async migration when TTM is used,
so the paths we care about are related to TTM.

The mmap path is handled by having the fence in ttm_bo->moving,
when pinning, the binding only becomes available after the moving
fence is signaled, and pinning a cpu map will only work after
the moving fence signals.

This should close all holes where userspace can read a buffer
before it's fully migrated.

v2:
- Fix a couple of SPARSE warnings
v3:
- Fix a NULL pointer dereference
v4:
- Ditch the moving fence waiting for i915_vma_pin_iomap() and
  replace with a verification that the vma is already bound.
  (Matthew Auld)
- Squash with a previous patch introducing moving fence waiting and
  accessing interfaces (Matthew Auld)
- Rename to indicated that we also add support for sync waiting.

- Fix compilation failure if !CONFIG_DRM_I915_DEBUG_GEM

deadlock if migrating buffer using sdma and waiting for sdma done

Remove VMC from IH storm client, enable ring1 write pointer

other interrupts while driver is handling retry fault.

IH ring1 write pointer doesn't writeback to memory by IH, and ring1
write pointer recorded by self-irq is not updated, so always read
the latest ring1 write pointer from register.

Fixes: 9f4f2c1a35 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov")

For sriov XGMI  configuration, the host driver will handle the hive reset,
so in guest side, the reset_sriov only be called once on one device. This will
make kfd post_reset unblanced with kfd pre_reset since kfd pre_reset already

2276ee6d1b drm/amd/display: Reset link encoder assignments for GPU reset
[Why]
A warning appears in the log on GPU reset for
link_enc_cfg_link_encs_assign for the following condition:

ASSERT(state->res_ctx.link_enc_cfg_ctx.link_enc_assignments[i].valid == false);

This is not expected behavior and may result in link encoders being
incorrectly assigned.

[How]
The dc->current_state is backed up into dm->cached_dc_state before
we commit 0 streams.

DC will clear link encoder assignments on the real state but the
changes won't propagate over to the copy we made before the
0 streams commit.

DC expects that link encoder assignments are *not* valid
when committing a state, so as a workaround it needs to be cleared
before passing it back into DC.

IH ring1 write pointer doesn't writeback to memory by IH, and ring1
write pointer recorded by self-irq is not updated, so always read

f53e191e2b drm/amd/display: fixed an error related to 4:2:0/4:2:2 DSC
[Why]
OPTC_BYTES_PER_PIXEL calculation for 4:2:2 and 4:2:0 could have error.

[How]
Change to use following formula:
OPTC_DSC_BYTES_PER_PIXEL = ceiling((chunk size * 2^28) / slice width)

v2: squash in 64 bit divide fix (Alex)

e048834c20 drm/hyperv: Fix device removal on Gen1 VMs
The Hyper-V DRM driver tries to free MMIO region on removing
the device regardless of VM type, while Gen1 VMs don't use MMIO
and hence causing the kernel to crash on a NULL pointer dereference.

Fix this by making deallocating MMIO only on Gen2 machines and implement
removal for Gen1

5979873ebb drm/i915/pmu: Increase the live_engine_busy_stats sample period
Irrespective of the backend for request submissions, busyness for an
engine with an active context is calculated using:

busyness = total + (current_time - context_switch_in_time)

In execlists mode of operation, the context switch events are handled
by the CPU. Context switch in/out time and current_time are captured
in CPU time domain using ktime_get().

In GuC mode of submission, context switch events are handled by GuC and
the times in the above formula are captured in GT clock domain. This
information is shared with the CPU through shared memory. This results
in 2 caveats:

1) The time taken between start of a batch and the time that CPU is able
to see the context_switch_in_time in shared memory is dependent on GuC
and memory bandwidth constraints.

2) Determining current_time requires an MMIO read that can take anywhere
between a few us to a couple ms. A reference CPU time is captured soon
after reading the MMIO so that the caller can compare the cpu delta
between 2 busyness samples. The issue here is that the CPU delta and the
busyness delta can be skewed because of the time taken to read the
register.

These 2 factors affect the accuracy of the selftest -
live_engine_busy_stats. For (1) the selftest waits until busyness stats
are visible to the CPU. The effects of (2) are more prominent for the
current busyness sample period of 100 us. Increase the busyness sample
period from 100 us to 10 ms to overccome (2).

11b4da9827 drm/amdgpu: partially revert "svm bo enable_signal call condition"
Partially revert commit 5f319c5c21.

First of all this is illegal use of RCU to call dma_fence_enable_sw_signaling()
since we don't hold a reference to the fence in question and can crash badly.

Then the code doesn't seem to have the intended effect since only the
exclusive fence is handled, but the KFD fences are always added as shared fence.

Only keep the handling to throw away the content of SVM BOs.

6984fa418b drm/amd/display: Set plane update flags for all planes in reset
[Why]
We're only setting the flags on stream[0]'s planes so this logic fails
if we have more than one stream in the state.

This can cause a page flip timeout with multiple displays in the
configuration.

[How]
Index into the stream_status array using the stream index - it's a 1:1
mapping.

85fb8bb9d4 drm/amd/display: Run full global validation in dc_commit_state
[Why]
Dynamic link encoder assignment expects that it can modify DC
current_state and the links associated with the incoming state when
performing full validation.

This does not align with our actual synchronization constraints
in DM's atomic_check.

[How]
Since link encoder assignment only happens as part of full validation
we can just use fast validation as part of atomic_check instead.

This satisfy's DC interface requirements and skips the DML calculations
needed for pipe programming - hopefully speeding up things a little bit
to offset the cost of double validation during stream modification.

We already do this as part of dc_commit_updates_for_stream()
with validate_bandwidth(), so extend this to dc_commit_state() as
well.

524a0ba6fa drm/amd/display: Fix DPIA outbox timeout after GPU reset
[Why]
The HW interrupt gets disabled after GPU reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and
black screen with (or without) DPIA links connected.

Re-enable the interrupt after GPU reset like we do for the other
DC interrupts.

6c5af7d2f8 drm/amdgpu: fix set scaling mode Full/Full aspect/Center not works on vga and dvi connectors
amdgpu_connector_vga_get_modes missed function amdgpu_get_native_mode
which assign amdgpu_encoder->native_mode with *preferred_mode result in
amdgpu_encoder->native_mode.clock always be 0. That will cause
amdgpu_connector_set_property returned early on:
if ((rmx_type != DRM_MODE_SCALE_NONE) &&
	(amdgpu_encoder->native_mode.clock == 0))
when we try to set scaling mode Full/Full aspect/Center.
Add the missing function to amdgpu_connector_vga_get_mode can fix this.
It also works on dvi connectors because
amdgpu_connector_dvi_helper_funcs.get_mode use the same method.

b295ce3991 drm/amd/display: Fix OLED brightness control on eDP
[Why]
After commit ("drm/amdgpu/display: add support for multiple backlights")
number of eDPs is defined while registering backlight device.
However the panel's extended caps get updated once before register call.
That leads to regression with extended caps like oled brightness control.

[How]
Update connector ext caps after register_backlight_device

d26c4ffba6 drm/amd/display: Code change for DML isolation

DML itself is SW only, putting the logic as part of resource makes it
hw dependent and thus impossible to compile separately from dc.
Separate compilation is critical for unit testing as well as bbox tool

[how]

Copy logic from the validation functions into dml wrapper as base
implementation. Dml wrapper has internal/static implementations
for all helpers, and does not reference other functions.

d03fcc1de0 drm/msm/dp: Avoid unpowered AUX xfers that caused crashes
If you happened to try to access `/dev/drm_dp_aux` devices provided by
the MSM DP AUX driver too early at bootup you could go boom. Let's
avoid that by only allowing AUX transfers when the controller is
powered up.

Specifically the crash that was seen (on Chrome OS 5.4 tree with
relevant backports):
  Kernel panic - not syncing: Asynchronous SError Interrupt
  CPU: 0 PID: 3131 Comm: fwupd Not tainted 5.4.144-16620-g28af11b73efb #1
  Hardware name: Google Lazor (rev3+) with KB Backlight (DT)
  Call trace:

   panic+0x150/0x390

   drm_dp_dpcd_read+0x64/0x10c
   auxdev_read_iter+0xd4/0x1c4

I did a little bit of tracing and found that:
* We register the AUX device very early at bootup.
* Power isn't actually turned on for my system until
  hpd_event_thread() -> dp_display_host_init() -> dp_power_init()
* You can see that dp_power_init() calls dp_aux_init() which is where
  we start allowing AUX channel requests to go through.

In general this patch is a bit of a bandaid but at least it gets us
out of the current state where userspace acting at the wrong time can
fully crash the system.
* I think the more proper fix (which requires quite a bit more
  changes) is to power stuff on while an AUX transfer is
  happening. This is like the solution we did for ti-sn65dsi86. This
  might be required for us to move to populating the panel via the
  DP-AUX bus.
* Another fix considered was to dynamically register / unregister. I
  tried that at <https://crrev.com/c/3169431/3> but it got
  ugly. Currently there's a bug where the pm_runtime() state isn't
  tracked properly and that causes us to just keep registering more
  and more.

527bab0473 drm/i915/rpm: Enable runtime pm autosuspend by default
Let's enable runtime pm autosuspend by default everywhere.
So, we can allow D3hot and bigger power savings on idle scenarios.

But at this time let's not touch the autosuspend_delay time,
what caused some regression on our previous attempt.

Also, the latest identified issue on GuC PM has been fixed by
commit 1a52faed31 ("drm/i915/guc: Take GT PM ref when deregistering
context")

v1: Enable runtime pm autosuspend by default for Gen12
and later versions.

v2: Enable runtime pm autosuspend by default for all
platforms(Syrjala Ville)

v3: Change commit message(Nikula Jani)

3466d9e217 drm/msm: Fix mmap to include VM_IO and VM_DONTDUMP
In commit 510410bfc0 ("drm/msm: Implement mmap as GEM object
function") we switched to a new/cleaner method of doing things. That's
good, but we missed a little bit.

Before that commit, we used to _first_ run through the
drm_gem_mmap_obj() case where `obj->funcs->mmap()` was NULL. That meant
that we ran:

  vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND | VM_DONTDUMP;
  vma->vm_page_prot = pgprot_writecombine(vm_get_page_prot(vma->vm_flags));
  vma->vm_page_prot = pgprot_decrypted(vma->vm_page_prot);

...and _then_ we modified those mappings with our own. Now that
`obj->funcs->mmap()` is no longer NULL we don't run the default
code. It looks like the fact that the vm_flags got VM_IO / VM_DONTDUMP
was important because we're now getting crashes on Chromebooks that
use ARC++ while logging out. Specifically a crash that looks like this
(this is on a 5.10 kernel w/ relevant backports but also seen on a
5.15 kernel):

Let's add the two flags back in.

While we're at it, the fact that we aren't running the default means
that we _don't_ need to clear out VM_PFNMAP, so remove that and save
an instruction.

NOTE: it was confirmed that VM_IO was the important flag to fix the
problem I was seeing, but adding back VM_DONTDUMP seems like a sane
thing to do so I'm doing that too.

10ceccb8d7 drm/i915: move the pre_pin earlier
In intel_context_do_pin_ww, when calling into the pre_pin hook(which is
passed the ww context) it could in theory return -EDEADLK(which is very
likely with debug kernels), once we start adding more ww locking in there,
like in the next patch. If so then we need to be mindful of having to
restart the do_pin at this point.

If this is the kernel_context, or some other early in-kernel context
where we have yet to setup the default_state, then we always inhibit the
context restore, and instead rely on the delayed active_release to set
the CONTEXT_VALID_BIT for us(if we even care), which should indicate
that we have context switched away, and that our newly saved context
state should now be valid. However, since we currently grab the active
reference before the potential ww dance, we can end up setting the
CONTEXT_VALID_BIT much too early, if we need to backoff, and then upon
re-trying the do_pin, we could potentially cause the hardware to
incorrectly load some garbage context state when later context switching
to that context, but at the very least this will trigger the
GEM_BUG_ON() in __engine_unpark. For now let's just move any ww dance
stuff prior to arming the active reference.

For normal user contexts this shouldn't be a concern, since we should
already have the default_state ready when initialising the lrc state,
and so there should be no concern with active_release somehow
prematurely setting the CONTEXT_VALID_BIT.

v2(Thomas):
  - Also re-order the onion unwind

drm/aspeed: Fix vga_pw sysfs output
Before the drm driver had support for this file there was a driver that
exposed the contents of the vga password register to userspace. It would
present the entire register instead of interpreting it.

The drm implementation chose to mask of the lower bit, without explaining
why. This breaks the existing userspace, which is looking for 0xa8 in
the lower byte.

Change our implementation to expose the entire register.

99510e1afb drm/i915: Disable DSB usage for now
Turns out the DSB has trouble correctly loading the gamma LUT.
From a cursory look maybe like some entries do not load
properly, or they get loaded with some gibberish. Unfortunately
our current kms_color/etc. tests do not seem to catch this.

I had a brief look at the generated DSB batch and it looked
correct. Tried a few quick tricks like writing the index
register twice/etc. but didn't see any improvement.
Also tried switching to the 10bit gamma mode in case
there is yet another issue with the multi-segment mode, but
even the 10bit mode was showing issues.

Switching to mmio fixes all of it. I suppose one theory is that
maybe the DSB bangs on the LUT too quickly and it can't keep up
and instead some data either gets dropped or corrupted. To confirm
that someone should try to slow down the DSB's progress a bit.
Another thought was that maybe the LUT has crappy dual porting
and you get contention if you try to load it during active
scanout. But why then would the mmio path work, unless it's
just sufficiently slow?

Whatever the case, this is currently busted so let's disable
it until we get to the root of the problem.

0088d39b6a drm/i915: Do vblank evasion correctly if vrr push has already been sent
Let's adjust the vblank evasion to account for the case where
a push has already been sent. In that case the vblank exit will start
at vmin vblank start (as opposed to vmax vblank start when no push
has been sent).

This should minimize the effects of the tiny race between sampling
the frame counter vs. intel_vrr_send_push() during the previous frame.
This will also be required if we want to do mailbox style updates with
vrr since then we'd definitely do multiple commits per frame. Currently
mailbox updates are only used by the legacy cursor, but we don't do
vrr push for those.

4765d061d5 drm/i915: Move vrr push after the frame counter sampling again
Moving the vrr push to happen before sampling the frame counter
was wrong. If we are already in vblank when the push is sent
the vblank exit will start immediately which causes the sampled
frame counter to correspond to the next frame instead of the current
frame.

So put things back into the original order (except we should
keep the vrr push within the irq disable section to avoid
pointless irq related delays here).

We'll just have to accept the tiny race that exists between
sampling the frame counter vs. vrr push. And let's at least
document said race properly in a comment.

I suppose we could try to minimize the race by sampling the frame
counter just before sending the push, but that would require
changing drm_crtc_arm_vblank_event() to accept a caller provided
vblank counter value, so leave it be for now. Another thing we
could do is change the vblank evasion to account for the case
where a push was already sent. That would anyway be required
for mailbox style updates. Currently mailbox updates are only
used by the legacy cursor, but we don't do a vrr push for those.

563c9d4a5b drm/mediatek: Remove the pointer of struct cmdq_client
In mailbox rx_callback, it pass struct mbox_client to callback
function, but it could not map back to mtk_drm_crtc instance
because struct cmdq_client use a pointer to struct mbox_client:

struct cmdq_client {
	struct mbox_client client;
	struct mbox_chan *chan;
};

struct mtk_drm_crtc {
	/* client instance data */
	struct cmdq_client *cmdq_client;
};

so remove the pointer of struct cmdq_client and let mtk_drm_crtc
instance define cmdq_client as:

struct mtk_drm_crtc {
	/* client instance data */
	struct cmdq_client cmdq_client;
};

and in rx_callback function, use struct mbox_client to get
struct mtk_drm_crtc.

37fe0cf5fb drm/i915: Clarify probing order in intel_dp_aux_init_backlight_funcs()
Hooray! We've managed to hit enough bugs upstream that I've been able to
come up with a pretty solid explanation for how backlight controls are
actually supposed to be detected and used these days. As well, having the
rest of the PWM bits in VESA's backlight interface implemented seems to
have fixed all of the problematic brightness controls laptop panels that
we've hit so far.

So, let's actually document this instead of just calling the laptop panels
liars. As well, I would like to formally apologize to all of the laptop
panels I called liars. I'm sorry laptop panels, hopefully you can all
forgive me and we can move past this~

f58a435311 drm/dp, drm/i915: Add support for VESA backlights using PWM for brightness control
Now that we've added support to i915 for controlling panel backlights that
need PWM to be enabled/disabled, let's finalize this and add support for
controlling brightness levels via PWM as well. This should hopefully put us
towards the path of supporting _ALL_ backlights via VESA's DPCD interface
which would allow us to finally start trusting the DPCD again.

Note however that we still don't enable using this by default on i915 when
it's not needed, primarily because I haven't yet had a chance to confirm if
it's safe to do this on the one machine in Intel's CI that had an issue
with this: samus-fi-bdw. I have done basic testing of this on other
machines though, by manually patching i915 to force it into PWM-only mode
on some of my laptops.

646596485e drm/dp: Don't read back backlight mode in drm_edp_backlight_enable()
As it turns out, apparently some machines will actually leave additional
backlight functionality like dynamic backlight control on before the OS
loads. Currently we don't take care to disable unsupported features when
writing back the backlight mode, which can lead to some rather strange
looking behavior when adjusting the backlight.

So, let's fix this by just not reading back the current backlight mode on
initial enable. I don't think there should really be any downsides to this,
and this will ensure we don't leave any unsupported functionality enabled.

This should fix at least one (but not all) of the issues seen with DPCD
backlight support on fi-bdw-samus

This simply adds proper support for panel backlights that can be controlled

enable and disable the backlight via PWM instead of via the DPCD interface.
We also enable this by default, in order to fix some people's backlights

For reference, backlights that require this and use VESA's backlight
interface tend to be laptops with hybrid GPUs, but this very well may

1328e395fd drm/amd/display: Fix detection of aligned DMUB firmware meta info
[Why]
A built firmware binary may be aligned to 16-bytes with padding at the
end as necessary. In the case that padding was applied the meta info
will not be detected correctly and we won't be able to allocate the
appropriate firmware and tracebuffer sizes.

[How]
To maintain compatibility with already released firmware where this
occurs we need to try every meta offset from 0..15 inclusive.

Extract out the meta info checker into a helper function that's called
for each of these offsets and exit early when we've found it.

cfd3f70ebd drm/amd/display: Use link_enc_cfg API for queries.
[Why]
The link_enc_cfg API operates in one of two modes depending on the stage
of application of dc_state to hardware. The API is the safest way to
query link encoder assignments.

[How]
Use results of link encoder assignment query using link_enc_cfg API.

[WHY]
With RGB MPO enabled, playing a video with multiple displays connected
results in underflow when closing the video window

[HOW]
Reverted the old change to fix this problem, which prevented pipe splits
for multiple display configurations and caused high MCLK speeds during
idle. Added a two step call to dc_update_planes_and_stream, first time
with pipe split disabled and the second time with pipe split enabled,
which fixed the underflow issue

a59308a5fb drm/i915: Fix fastsets on TypeC ports following a non-blocking modeset
After a non-blocking modeset on a TypeC port's CRTC - possibly blocked
later in drm_atomic_helper_wait_for_dependencies() - a fastset on the
same CRTC may copy the state of CRTC before this gets updated to reflect
the up-to-date DP-alt vs. TBT-alt TypeC mode DPLL used for the CRTC. In
this case after the first (non-blocking) commit completes enabling the
DPLL required for the up-to-date TypeC mode the following fastset will
update the CRTC state pointing to the wrong DPLL. A subsequent disabling
modeset will try to disable the wrong PLL, triggering a state checker
WARN (and leaving the DPLL which is actually used active for good).

Fix the above race by copying the DPLL state for fastset CRTCs from the
old CRTC state at the point where it's guaranteed to be up-to-date
already. This could be handled in the encoder's update_prepare() hook as
well, but that's a bigger change, which is better done as a follow-up.

v2: Copy dpll_hw_state as well. (Ville)

7e2e69ed46 drm/i915: Fix i915_request fence wait semantics
The i915_request fence wait behaves differently for timeout = 0
compared to expected dma-fence behavior.

i915 behavior:
- Unsignaled: -ETIME
- Signaled: 0 (= timeout)

Expected:
- Unsignaled: 0
- Signaled: 1

a193f3b4e0 drm/shmem-helper: Pass GEM shmem object in public interfaces
Change all GEM SHMEM object functions that receive a GEM object
of type struct drm_gem_object to expect an object of type
struct drm_gem_shmem_object instead.

This change reduces the number of upcasts from struct drm_gem_object
by moving them into callers. The C compiler can now verify that the
GEM SHMEM functions are called with the correct type.

For consistency, the patch also renames drm_gem_shmem_free_object to
drm_gem_shmem_free. It further updates documentation for a number of
functions.

This is because DRM_SUN6I_DSI selects PHY_SUN6I_MIPI_DPHY

22da19f900 drm/nouveau/device: use snprintf() to replace strncpy() to avoid NUL-terminated string loss
Following warning is found when using W=1 to build kernel:

In function ‘nvkm_udevice_info’,
    inlined from ‘nvkm_udevice_mthd’ at drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:195:10:
drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:164:2: warning: ‘strncpy’ specified bound 16 equals destination size [-Wstringop-truncation]
  164 |  strncpy(args->v0.chip, device->chip->name, sizeof(args->v0.chip));
drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:165:2: warning: ‘strncpy’ specified bound 64 equals destination size [-Wstringop-truncation]
  165 |  strncpy(args->v0.name, device->name, sizeof(args->v0.name));

The reason of this warning is strncpy() does not guarantee that the
destination buffer will be NUL terminated. If the length of source string
is bigger than number we set by third input parameter, only a part of
characters is copied to the destination, and no NUL-terminated string is
automatically added. There are some potential risks.

So use snprintf() to replace strncpy().

79af598a5b drm/nouveau/kms/nv50-: Always validate LUTs in nv50_head_atomic_check_lut()
When it comes to gamma or degamma luts, nouveau will actually skip the
calculation of certain LUTs depending on the head and plane states. For
instance, when the head is disabled we don't perform any error checking on
the gamma LUT, and likewise if no planes are present and enabled in our
atomic state we will skip error checking the degamma LUT. This is a bit of
a problem though, since the per-head gamma and degamma props in DRM can be
changed even while a head is disabled - a situation which can be triggered
by the igt testcase mentioned down below.

Originally I thought this was a bit silly and was tempted to just fix the
igt test to only set gamma/degamma with the head enabled. After a bit of
thinking though I realized we should fix this in nouveau. This is because
if a program decides to set an invalid LUT for a head before enabling the
head, such a property change would succeed while also making it impossible
to turn the head back on until the LUT is removed or corrected - something
that could be painful for a user to figure out.

So, fix this checking both degamma and gamma LUTs unconditionally during
atomic checks. We start by calling nv50_head_atomic_check_lut() regardless
of whether the head is active or not in nv50_head_atomic_check(). Then we
move the ilut error checking into nv50_head_atomic_check_lut() and add a
per-head hook for it, primarily because as a per-CRTC property DRM we want
the LUT to be error checked by the head any time it's included in an atomic
state. Of course though, actual programming of the degamma lut to hardware
is still handled in each plane's atomic check and commit.

c0a808b069 drm/nouveau/kms/nv50-: Correct size checks for cursors
Found this while trying to make some changes to the kms_cursor_crc test.
curs507a_acquire checks that the width and height of the cursor framebuffer
are equal (asyw->image.{w,h}). This isn't entirely correct though, as the
height of the cursor can be larger than the size of the cursor, as long as
the width is the same as the cursor size and there's no framebuffer offset.

Note that I'm not entirely sure why this wasn't previously breaking
kms_cursor_crc tests - they all set up cursors with the height being one
pixel larger than the actual size of the cursor. But this seems to fix
things, and the code before was definitely incorrect - so it's not really
worth looking into further imho.

Changes since v1:
* Don't use crtc_w everywhere for determining cursor layout, just use fb
  size again
* Change check so that we only check that the w/h of the cursor plane is
  the same, the width of the scanout surface is the same as the framebuffer
  width, and that there's no offset being used for the cursor surface.

1d2271d2fb drm/nouveau/pmu/gm200-: avoid touching PMU outside of DEVINIT/PREOS/ACR
There have been reports of the WFI timing out on some boards, and a
patch was proposed to just remove it.  This stuff is rather fragile,
and I believe the WFI might be needed with our FW prior to GM200.

However, we probably should not be touching PMU during init on GPUs
where we depend on NVIDIA FW, outside of limited circumstances, so
this should be a somewhat safer change that achieves the desired
result.

23244f67ed drm/nouveau/kms/nvd9-nv138: Fix CRC calculation for the cursor channel
Something that didn't get noticed until I started running cursor tests:
we're accidentally disabling an option for CRC calculation that's enabled
by default: WidePipeCrc, which controls whether we use the full width of
the data in the display pipe in order calculate CRCs. Having this disabled
apparently causes frames with the cursor plane enabled to generate
different CRCs than frames without the cursor plane enabled, even if the
frames are pixel-equivalent.

So, let's make sure to enable this and fix a bunch of cursor related tests
in IGT.

v2:
* Nvidia added the specific bit we were using to fix this issues to
  open-gpu-docs, so pull in the actual macro definitions for it

57cbdbe65e drm/nouveau/kms/nv140-: Use hard-coded wndws or core channel for CRC channel
Originally it was assumed based on Nvidia's open-gpu-docs and testing that
NVDisplay required that at least one wndw which belongs to a given head to
be used as the controlling channel
(NVC37D_HEAD_SET_CRC_CONTROL_CONTROLLING_CHANNEL) in order for CRC capture
to function. While this is the case on Volta, Turing actually adds the
ability to instead use the core channel as the controlling channel. For
Turing this is quite useful, as it means that we can always default to the
core channel as the controlling channel and we don't need to be concerned
about ensuring we have at least one wndw channel owned by a head with CRC
output enabled. While Volta lacks this ability, Volta conveniently also
lacks flexible wndw mapping - meaning that we can always rely on each head
having four wndw channels mapped to it regardless of the atomic state.

So, simply use the hard-coded wndw mappings we're guaranteed to have on
Volta as the controlling channel, and use the core channel as the
controlling channel for Turing+. As a result this also renders the plane
ownership logic in nv50_crc_atomic_check() unnessecary, which gives us one
less thing to implement when we get support for flexible wndw mapping. We
also can entirely drop the wndw parameter from our set_src callbacks, and
the atomic state.

0af5e0b411 drm/meson: encoder_hdmi: switch to bridge DRM_BRIDGE_ATTACH_NO_CONNECTOR
This implements the necessary change to no more use the embedded
connector in dw-hdmi and use the dedicated bridge connector driver
by passing DRM_BRIDGE_ATTACH_NO_CONNECTOR to the bridge attach call.

The necessary connector properties are added to handle the same
functionalities as the embedded dw-hdmi connector, i.e. the HDR
metadata, the CEC notifier & other flags.

The dw-hdmi output_port is set to 1 in order to look for a connector
next bridge in order to get DRM_BRIDGE_ATTACH_NO_CONNECTOR working.

e67f6037ae drm/meson: split out encoder from meson_dw_hdmi
This moves all the non-DW-HDMI code where it should be:
an encoder in the drm/meson core driver.

The bridge functions are copied as-is, except:
- the encoder init uses the simple kms helper
- the mode_set has been moved to atomic_enable()
- debug prints are converted to dev_debg()

For now the bridge attach flags is 0, DRM_BRIDGE_ATTACH_NO_CONNECTOR
will be handled later.

The meson dw-hdmi glue is slightly fixed to live without the
encoder in the same driver.

7cd70656d1 drm/bridge: display-connector: implement bus fmts callbacks
Since this bridge is tied to the connector, it acts like a passthrough,
so concerning the output & input bus formats, either pass the bus formats from the
previous bridge or return fallback data like done in the bridge function:
drm_atomic_bridge_chain_select_bus_fmts() & select_bus_fmt_recursive.

This permits avoiding skipping the negociation if the remaining bridge chain has
all the bits in place.

Without this bus fmt negociation breaks on drm/meson HDMI pipeline when attaching
dw-hdmi with DRM_BRIDGE_ATTACH_NO_CONNECTOR, because the last bridge of the
display-connector doesn't implement buf fmt callbacks and MEDIA_BUS_FMT_FIXED
is used leading to select an unsupported default bus format from dw-hdmi.

3f2532d65a drm/bridge: dw-hdmi: handle ELD when DRM_BRIDGE_ATTACH_NO_CONNECTOR
The current ELD handling takes the internal connector ELD buffer and
shares it to the I2S and AHB sub-driver.

But with DRM_BRIDGE_ATTACH_NO_CONNECTOR, the connector is created
elsewhere (or not), and an eventual connector is known only
if the bridge chain up to a connector is enabled.

The current dw-hdmi code gets the current connector from
atomic_enable() so use the already stored connector pointer and
replace the buffer pointer with a callback returning the current
connector ELD buffer.

Since a connector is not always available, either pass an empty
ELD to the alsa HDMI driver or don't call snd_pcm_hw_constraint_eld()
in AHB driver.

c582ffadbe drm/i915/psr: Fix PSR2 handling of multiplanar format
When a plane with a multiplanar format is added to the state by
drm_atomic_add_affected_planes(), only the UV plane is
added, so a intel_atomic_get_new_plane_state() call to get the Y
plane state can return a null pointer.
To fix this, intel_atomic_get_plane_state() should be called and
the return needs to be checked for errors, as it could return a EAGAIN
as other atomic state could be holding the lock for the Y plane.

Other issue with the patch being fixed is that the Y plane is not
being committed to hardware because the corresponded plane bit is not
set in update_planes when UV and Y planes are added to the state by
drm_atomic_add_affected_planes().

ab09243aa9 mm/migrate.c: remove MIGRATE_PFN_LOCKED
MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a
source page was already locked during migrate_vma_collect().  If it
wasn't then the a second attempt is made to lock the page.  However if
the first attempt failed it's unlikely a second attempt will succeed,
and the retry adds complexity.  So clean this up by removing the retry
and MIGRATE_PFN_LOCKED flag.

Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag
set, but nothing actually checks that.

e9d9f9582c drm/bridge: parade-ps8640: Populate devices on aux-bus
Conventionally, panel is listed under the root of the device tree.
When userland asks for display mode, ps8640 bridge is responsible
for returning EDID when ps8640_bridge_get_edid() is called.

Now enable a new option of listing panel under "aux-bus" of ps8640
bridge node in the device tree. In this case, panel driver can retrieve
EDID by triggering AUX transactions, without ps8640_bridge_get_edid()
calls at all.

To prevent the "old" and "new" options from interfering with each
other's logic flow, disable DRM_BRIDGE_OP_EDID when the new option
is taken.

826cff3f7e drm/bridge: parade-ps8640: Enable runtime power management
Fit ps8640 driver into runtime power management framework:

First, break _poweron() to 3 parts: (1) turn on power and wait for
ps8640's internal MCU to finish init (2) check panel HPD (which is
proxied by GPIO9) (3) the other configs. As runtime_resume() can be
called before panel is powered, we only add (1) to _resume() and leave
(2)(3) to _pre_enable(). We also add (2) to _aux_transfer() as we want
to ensure panel HPD is asserted before we start AUX CH transactions.

Second, the original driver has a mysterious delay of 50 ms between (2)
and (3). Since Parade's support can't explain what the delay is for,
and we don't see removing the delay break any boards at hand, remove
the delay to fit into this driver change.

In addition, rename "powered" to "pre_enabled" and don't check for it
in the pm_runtime calls. The pm_runtime calls are already refcounted
so there's no reason to check there. The other user of "powered",
_get_edid(), only cares if pre_enable() has already been called.

Lastly, change some existing DRM_...() logging to dev_...() along the
way, since DRM_...() seem to be deprecated in [1].

0242cd3a53 drm/i915/fbc: Introduce .nuke() vfunc
Eliminate yet another if-ladder by adding .nuke() vfunc.

We also rename all *_recompress() stuff to *_nuke() since
that's the terminology the spec uses. Also "recompress"
is a bit confusing by perhaps implying that this triggers
an immediate recompression. Depending on the hardware that
may definitely not be the case, and in general we don't
specifically know when the hardware decides to compress.
So all we do is "nuke" the current compressed framebuffer
and leave it up to the hardware to recompress later if it
so chooses.

6874f95816 drm/i915/fbc: Extract helpers to compute FBC control register values
Declutter the *_fbc_activate() functions by pulling all the
control register value computations into helpers.

I left the enable bit in *_fbc_activate() in the hopes of maybe
using the helpers in the *_fbc_deactivate() paths as well instead
of the current rmw approach. That won't be possible at least
quite yet since we clobber the fbc->params before deactivating
FBC so we could end up changing some of the values live, which
given FBC's lack of/poor double buffering would likely not go
so well.

Currently we reset the whole PCON linkConfig DPCD to set the TMDS mode.
This also resets the Source control bit and HDMI link enable bit and
goes to autonomous mode of operation, which is seen to spoil the PCONs

This patch avoids resetting the PCON link config register and sets only
the source control bit, with FRL Enable bit set to 0 (TMDS mode) in the

4375d6255d drm/amd/display: reject both non-zero src_x and src_y only for DCN1x
[Why]
Video plane gets rejected for non-zero src_y and src_x on DCN2.x.

[How]
Limit the rejection till DCN1.x and verified MPO, by dragging video
playback beyond display's left (0, 0) co-ordinates.

6e12059463 drm/tidss: Make use of the helper macro SET_RUNTIME_PM_OPS()
Use the helper macro SET_RUNTIME_PM_OPS() instead of the verbose
operators ".runtime_suspend/.runtime_resume", because the
SET_RUNTIME_PM_OPS() is a nice helper macro that could be brought
in to make code a little more concise.

1f366c6856 drm/omap: increase DSS5 max tv pclk to 192MHz
DSS5's maximum tv pclk rate (i.e. HDMI) is set to 186MHz, which comes
from the TRM (DPLL_HDMI_CLK1 frequency must be lower than 186 MHz). To
support DRA76's wide screen HDMI feature, we need to increase this
maximum rate.

Testing shows that the PLL seems to work fine even with ~240MHz clocks,
and even the HDMI output at that clock is stable enough for monitors to
show a picture. This holds true for all DRA7 and AM5 SoCs (and probably
also for OMAP5).

However, the highest we can go without big refactoring to the clocking
code is 192MHz, as that is the DSS func clock we get from the PRCM. So,
increase the max HDMI pixel clock to 192MHz for now, to allow some more
2k+ modes to work.

This patch never had a clear confirmation from HW people, but this
change stayed on production trees for multiple years without any report
on an eventual breakage.

9030e39cd1 drm/i915/selftests: Use clear_and_wake_up_bit() for the per-engine reset bitlocks
Some selftests assume that nothing will attempt to grab these bitlocks
while they are held by the selftests. With GuC, for example, that is
not true because the hanging workloads may cause the GuC code to attempt
to grab them for a global reset, and that may cause it to end up
sleeping on the bit never waking up. Regardless whether that will be
the final solution for GuC, use clear_and_wake_up_bit() pending a more
thorough investigation on how this should be handled moving forward.

To be clear this needs to be a temporary solution. If we can't find
an in-kernel locking primitive to use here, we should at the very least
add lockdep annotation to these bitlocks with a thorough explanation
as to why we need to use bits.

v3:
- Use GEM_BUG_ON(test_and_set_bit()) rather than set_bit() to verify
  the assumption that nothing is holding the reset locks when we
  attempt to grab them. (Chris Wilson)
