With a second DP monitor connected, drm_atomic_state in dm atomic check
sequence does not include the connector state for the old/existing/first
DP monitor. In such case, dsc determination policy would hit a null ptr
when it tries to iterate the old/existing stream that does not have a
valid connector state attached to it. When that happens, dm atomic check
should call drm_atomic_get_connector_state for a new connector state.
Existing dm has already done that, except for RV due to it does not have
official support of dsc where .num_dsc is not defined in dcn10 resource
cap, that prevent from getting drm_atomic_get_connector_state called.
So, skip dsc determination policy for ASICs that don't have DSC support.

f0b6dc034e drm/amd/display: Wrong colorimetry workaround
[ Upstream commit b1a98cf89a695d36c414653634ea7ba91b6e701f ]

[Why]
For FreeSync HDR, native color space flag in AMD VSIF(BT.709) should be
used when intepreting content and color space flag in VSC or AVI
infoFrame should be ignored. However, it turned out some userspace
application still use color flag in VSC or AVI infoFrame which is
incorrect.

[How]
Transfer function is used when building the VSC and AVI infoFrame. Set
colorimetry to BT.709 when all the following match:

1. Pixel format is YCbCr;
2. In FreeSync 2 HDR, color is COLOR_SPACE_2020_YCBCR;
3. Transfer function is TRANSFER_FUNC_GAMMA_22;

8dafc066c5 drm/buddy: fix range bias
commit f41900e4a6ef019d64a70394b0e0c3bd048d4ec8 upstream.

There is a corner case here where start/end is after/before the block
range we are currently checking. If so we need to be sure that splitting
the block will eventually give use the block size we need. To do that we
should adjust the block range to account for the start/end, and only
continue with the split if the size/alignment will fit the requested
size. Not doing so can result in leaving split blocks unmerged when it
eventually fails.

7d34b10786 drm/meson: Don't remove bridges which are created by other drivers
[ Upstream commit bd915ae73a2d78559b376ad2caf5e4ef51de2455 ]

Stop calling drm_bridge_remove() for bridges allocated/managed by other
drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}.
drm_bridge_remove() unregisters the bridge so it cannot be used
anymore. Doing so for bridges we don't own can lead to the video
pipeline not being able to come up after -EPROBE_DEFER of the VPU
because we're unregistering a bridge that's managed by another driver.
The other driver doesn't know that we have unregistered it's bridge
and on subsequent .probe() we're not able to find those bridges anymore
(since nobody re-creates them).

This fixes probe errors on Meson8b boards with the CVBS outputs enabled.

If the case the HDMI controller fails to bind, we try to unbind
all components before calling drm_dev_put() which makes drm_bridge_detach()
crash because unbinding the HDMI controller frees the bridge memory.

The solution is the unbind all components at the end like in the remove
path.

fd7b4f4fdc drm/syncobj: call drm_syncobj_fence_add_wait when WAIT_AVAILABLE flag is set
[ Upstream commit 3c43177ffb54ea5be97505eb8e2690e99ac96bc9 ]

When waiting for a syncobj timeline point whose fence has not yet been
submitted with the WAIT_FOR_SUBMIT flag, a callback is registered using
drm_syncobj_fence_add_wait and the thread is put to sleep until the
timeout expires. If the fence is submitted before then,
drm_syncobj_add_point will wake up the sleeping thread immediately which
will proceed to wait for the fence to be signaled.

However, if the WAIT_AVAILABLE flag is used instead,
drm_syncobj_fence_add_wait won't get called, meaning the waiting thread
will always sleep for the full timeout duration, even if the fence gets
submitted earlier. If it turns out that the fence *has* been submitted
by the time it eventually wakes up, it will still indicate to userspace
that the wait completed successfully (it won't return -ETIME), but it
will have taken much longer than it should have.

To fix this, we must call drm_syncobj_fence_add_wait if *either* the
WAIT_FOR_SUBMIT flag or the WAIT_AVAILABLE flag is set. The only
difference being that with WAIT_FOR_SUBMIT we will also wait for the
fence to be signaled after it has been submitted while with
WAIT_AVAILABLE we will return immediately.

b06a3b1cbd nouveau: fix function cast warnings
[ Upstream commit 0affdba22aca5573f9d989bcb1d71d32a6a03efe ]

clang-16 warns about casting between incompatible function types:

drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadow.c:161:10: error: cast from 'void (*)(const struct firmware *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
  161 |         .fini = (void(*)(void *))release_firmware,

This one was done to use the generic shadow_fw_release() function as a
callback for struct nvbios_source. Change it to use the same prototype
as the other five instances, with a trivial helper function that actually
calls release_firmware.

47647795a6 drm/ttm: Fix an invalid freeing on already freed page in error path
commit 40510a941d27d405a82dc3320823d875f94625df upstream.

If caching mode change fails due to, for example, OOM we
free the allocated pages in a two-step process. First the pages
for which the caching change has already succeeded. Secondly
the pages for which a caching change did not succeed.

However the second step was incorrectly freeing the pages already
freed in the first step.

[ Upstream commit 2ff33c759a4247c84ec0b7815f1f223e155ba82a ]

[why]
Originally, PMFW said min FCLK is 300Mhz, but min DCFCLK can be increased
to 400Mhz because min FCLK is now 600Mhz so FCLK >= 1.5 * DCFCLK hardware
requirement will still be satisfied. Increasing min DCFCLK addresses
underflow issues (underflow occurs when phantom pipe is turned on for some
Sub-Viewport configs).

[how]

e70123fdbe drm/amd/display: Increase frame-larger-than for all display_mode_vba files
commit e63e35f0164c43fbc1adb481d6604f253b9f9667 upstream.

After a recent change in LLVM, allmodconfig (which has CONFIG_KCSAN=y
and CONFIG_WERROR=y enabled) has a few new instances of
-Wframe-larger-than for the mode support and system configuration
functions:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn20/display_mode_vba_20v2.c:3393:6: error: stack frame size (2144) exceeds limit (2048) in 'dml20v2_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]

   3286 | void dml20_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
        |      ^
  1 error generated.

Without the sanitizers enabled, there are no warnings.

This was the catalyst for commit 6740ec97bcdb ("drm/amd/display:
Increase frame warning limit with KASAN or KCSAN in dml2") and that same
change was made to dml in commit 5b750b22530f ("drm/amd/display:
Increase frame warning limit with KASAN or KCSAN in dml") but the
frame_warn_flag variable was not applied to all files. Do so now to
clear up the warnings and make all these files consistent.

The brute force iommu_flush_iotlb_all() was good enough for unmap, but
in some cases a map operation could require removing a table pte entry
to replace with a block entry.  This also requires tlb invalidation.
Missing this was resulting an obscure iova fault on what should be a
valid buffer address.

efdd665ce1 drm/amd/display: Implement bounds check for stream encoder creation in DCN301
[ Upstream commit 58fca355ad37dcb5f785d9095db5f748b79c5dc2 ]

'stream_enc_regs' array is an array of dcn10_stream_enc_registers
structures. The array is initialized with four elements, corresponding
to the four calls to stream_enc_regs() in the array initializer. This
means that valid indices for this array are 0, 1, 2, and 3.

The error message 'stream_enc_regs' 4 <= 5 below, is indicating that
there is an attempt to access this array with an index of 5, which is
out of bounds. This could lead to undefined behavior

Here, eng_id is used as an index to access the stream_enc_regs array. If
eng_id is 5, this would result in an out-of-bounds access on the
stream_enc_regs array.

Thus fixing Buffer overflow error in dcn301_stream_encoder_create
reported by Smatch:

Chain exists of:
  (work_completion)(&svm_bo->eviction_work) --> &mm->mmap_lock --> &svms->lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----

                               lock(&svms->lock);
  lock((work_completion)(&svm_bo->eviction_work));

I believe this cannot really lead to a deadlock in practice, because
svm_range_evict_svm_bo_worker only takes the mmap_read_lock if the BO
refcount is non-0. That means it's impossible that svm_range_bo_release
is running concurrently. However, there is no good way to annotate this.

To avoid the problem, take a BO reference in
svm_range_schedule_evict_svm_bo instead of in the worker. That way it's
impossible for a BO to get freed while eviction work is pending and the
cancel_work_sync call in svm_range_bo_release can be eliminated.

v2: Use svm_bo_ref_unless_zero and explained why that's safe. Also
removed redundant checks that are already done in
amdkfd_fence_enable_signaling.

fb017c3e6a drm/amd/display: For prefetch mode > 0, extend prefetch if possible
[ Upstream commit dd4e4bb28843393065eed279e869fac248d03f0f ]

[Description]
For mode programming we want to extend the prefetch as much as possible
(up to oto, or as long as we can for equ) if we're not already applying
the 60us prefetch requirement. This is to avoid intermittent underflow
issues during prefetch.

The prefetch extension is applied under the following scenarios:
1. We're in prefetch mode 1 (i.e. we don't support MCLK switch in blank)
2. We're using subvp or drr methods of p-state switch, in which case we
   we don't care if prefetch takes up more of the blanking time

Mode programming typically chooses the smallest prefetch time possible
(i.e. highest bandwidth during prefetch) presumably to create margin between
p-states / c-states that happen in vblank and prefetch. Therefore we only
apply this prefetch extension when p-state in vblank is not required (UCLK
p-states take up the most vblank time).

fe80290b2a drm/exynos: Call drm_atomic_helper_shutdown() at shutdown/unbind time
[ Upstream commit 16ac5b21b31b439f03cdf44c153c5f5af94fb3eb ]

Based on grepping through the source code this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown time
and at driver unbind time. Among other things, this means that if a
panel is in use that it won't be cleanly powered off at system
shutdown time.

The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart and at driver remove (or unbind) time comes
straight out of the kernel doc "driver instance overview" in
drm_drv.c.

A few notes about this fix:
- When adding drm_atomic_helper_shutdown() to the unbind path, I added
  it after drm_kms_helper_poll_fini() since that's when other drivers
  seemed to have it.
- Technically with a previous patch, ("drm/atomic-helper:
  drm_atomic_helper_shutdown(NULL) should be a noop"), we don't
  actually need to check to see if our "drm" pointer is NULL before
  calling drm_atomic_helper_shutdown(). We'll leave the "if" test in,
  though, so that this patch can land without any dependencies. It
  could potentially be removed later.
- This patch also makes sure to set the drvdata to NULL in the case of
  bind errors to make sure that shutdown can't access freed data.
