kbuild: Strip trailing padding bytes from modules.builtin.modinfo
It is possible to force a specific version of python to be used when
building the kernel by passing PYTHON3= on the make command line.
However kernel-doc.py is currently called with python3 hard-coded and
thus ignores this setting.
Use $(PYTHON3) to run $(KERNELDOC) so that the desired version of
python is used.

[Why]
drm_dp_mst_topology_queue_probe() is used under the assumption that
mst is already initialized. If we connect system with SST first
then switch to the mst branch during suspend, we will fail probing
topology by calling the wrong API since the mst manager is yet to
be initialized.
[How]
At dm_resume(), once it's detected as mst branc connected, check if
the mst is initialized already. If not, call
dm_helpers_dp_mst_start_top_mgr() instead to initialize mst

On PF passthrough environment, after hibernate and then resume, coralgemm
will cause gpu page fault.
Mode1 reset happens during hibernate, but partition mode is not restored
on resume, register mmCP_HYP_XCP_CTL and mmCP_PSP_XCP_CTL is not right
after resume. When CP access the MQD BO, wrong stride size is used,
this will cause out of bound access on the MQD BO, resulting page fault.
The fix is to ensure gfx_v9_4_3_switch_compute_partition() is called
when resume from a hibernation.
KFD resume is called separately during a reset recovery or resume from
suspend sequence. Hence it's not required to be called as part of
partition switch.

(cherry picked from commit 5d1b32cfe4)
The DRM_GEM_SHMEM_HELPER helper requires MMU enabled because it uses
vmf_insert_pfn() in its mmap implementation. On NOMMU configurations
(e.g. some RISC-V randconfig builds), this symbol is unavailable and
selecting DRM_GEM_SHMEM_HELPER causes a modpost undefined reference:
ERROR: modpost: "vmf_insert_pfn" [drivers/gpu/drm/drm_shmem_helper.ko] undefined!
Normally, Kconfig prevents this helper from being selected when
CONFIG_MMU=n. However, in some randconfig builds (such as those used by
0day CI), select statements can override unmet dependencies, triggering
the issue.
Add an explicit dependency on MMU to DRM_PIXPAPER to prevent this.

Set the DMA mask before calling nvkm_device_ctor(), so that when the
flush page is created in nvkm_fb_ctor(), the allocation will not fail
if the page is outside of DMA address space, which can easily happen if
IOMMU is disable. In such situations, you will get an error like this:
nouveau 0000:65:00.0: DMA addr 0x0000000107c56000+4096 overflow (mask ffffffff, bus limit 0).
Commit 38f5359354 ("rm/nouveau/pci: set streaming DMA mask early")
set the mask after calling nvkm_device_ctor(), but back then there was
no flush page being created, which might explain why the mask wasn't
set earlier.
Flush page allocation was added in commit 5728d06419 ("drm/nouveau/fb:
handle sysmem flush page from common code"). nvkm_fb_ctor() calls
alloc_page(), which can allocate a page anywhere in system memory, but
then calls dma_map_page() on that page. But since the DMA mask is still
set to 32, the map can fail if the page is allocated above 4GB. This is
easy to reproduce on systems with a lot of memory and IOMMU disabled.
An alternative approach would be to force the allocation of the flush
page to low memory, by specifying __GFP_DMA32. However, this would
always allocate the page in low memory, even though the hardware can
access high memory.

The Mesa issue referenced below pointed out a possible deadlock:
[ 1231.611031] Possible interrupt unsafe locking scenario:
[ 1231.611033] CPU0 CPU1
[ 1231.611034] ---- ----
[ 1231.611035] lock(&xa->xa_lock#17);
[ 1231.611038] local_irq_disable();
[ 1231.611039] lock(&fence->lock);
[ 1231.611041] lock(&xa->xa_lock#17);
[ 1231.611044] <Interrupt>
[ 1231.611045] lock(&fence->lock);
[ 1231.611047]
*** DEADLOCK ***
In this example, CPU0 would be any function accessing job->dependencies
through the xa_* functions that don't disable interrupts (eg:
drm_sched_job_add_dependency(), drm_sched_entity_kill_jobs_cb()).
CPU1 is executing drm_sched_entity_kill_jobs_cb() as a fence signalling
callback so in an interrupt context. It will deadlock when trying to
grab the xa_lock which is already held by CPU0.
Replacing all xa_* usage by their xa_*_irq counterparts would fix
this issue, but Christian pointed out another issue: dma_fence_signal
takes fence.lock and so does dma_fence_add_callback.
dma_fence_signal() // locks f1.lock
-> drm_sched_entity_kill_jobs_cb()
-> foreach dependencies
-> dma_fence_add_callback() // locks f2.lock
This will deadlock if f1 and f2 share the same spinlock.
To fix both issues, the code iterating on dependencies and re-arming them
is moved out to drm_sched_entity_kill_jobs_work().

commit 978fa2f6d0 ("drm/amd/display: Use scaling for non-native
resolutions on eDP") started using the GPU scaler hardware to scale
when a non-native resolution was picked on eDP. This scaling was done
to fill the screen instead of maintain aspect ratio.
The idea was supposed to be that if a different scaling behavior is
preferred then the compositor would request it. The not following
aspect ratio behavior however isn't desirable, so adjust it to follow
aspect ratio and still try to fill screen.
Note: This will lead to black bars in some cases for non-native
resolutions. Compositors can request the previous behavior if desired.

When tick values are large, the multiplication by NSEC_PER_SEC is larger

The issue is seen in PMU busyness counters that look like they have
wrapped around due to bad conversion. i915 PMU implementation returns
monotonically increasing counters. If a count is lesser than previous
one, it will only return the larger value until the smaller value
catches up. The user will see this as zero delta between two

Preserve the I/O register bits in __ast_write8_i_masked() as specified
by preserve_mask. Accidentally OR-ing the output value into these will
overwrite the register's previous settings.
Fixes display output on the AST2300, where the screen can go blank at
boot. The driver's original commit 312fec1405 ("drm: Initial KMS
driver for AST (ASpeed Technologies) 2000 series (v2)") already added
the broken code. Commit 6f719373b9 ("drm/ast: Blank with VGACR17 sync
enable, always clear VGACRB6 sync off") triggered the bug.

This is the new API for allocating DRM bridges.
This conversion was missed during the initial conversion of all bridges to
the new API. Thus all kernels with commit 94d50c1a2c ("drm/bridge:
get/put the bridge reference in drm_bridge_attach/detach()") and using this
driver now warn due to drm_bridge_attach() incrementing the refcount, which
is not initialized without using devm_drm_bridge_alloc() for allocation.
To make the conversion simple and straightforward without messing up with
the drmm_simple_encoder_alloc(), move the struct drm_bridge from struct
imx_parallel_display_encoder to struct imx_parallel_display.
Also remove the 'struct imx_parallel_display *pd' from struct
imx_parallel_display_encoder, not needed anymore.

I planned to set the polarity of horizontal and vertical sync, but
accidentally described vertical sync twice with different polarity
instead.
Note, that there is no functional change, because the driver only
makes use of DRM_MODE_FLAG_P[HV]SYNC to divert from the default
active-low polarity.

Waking the device during a GT reset can lead to unintended memory
allocation, which is not allowed since GT resets occur in the reclaim
path. Prevent this by holding a PM reference while a reset is in flight.

the DEFINE_CLASS() macro creates an inline function and
the init args are passed down to it; since _ret is passed as an int,
whatever value is set inside the function is not visible to the caller.
Pass _ret as a pointer so its value propagates to the caller.

YUV formats on this hardware needs scaling for chroma planes. However it
is not implemented for QSEED2 which breaks display pipeline if YUV format
is used (causing partial and corrupted output with PPDONE timeouts).
This patch temporarily disables YUV by switching affected sub-block to
RGB only format list.

UBWC-related register configuration for writeback is not implemented in
the driver yet but there aren't any checks for non-linear modifiers in
atomic_check. Thus when compressed framebuffer is attached to writeback
connector it will be filled with linear image data. This patch forbids
non-linear modifiers for writeback framebuffers until UBWC support for
writeback is properly implemented.

In _dpu_plane_setup_pixel_ext function instead of dividing just chroma
source resolution once (component 1 and 2), second component is divided
once more because src_w and src_h variable is reused between iterations.
Third component receives wrong source resolution too (from component 2).
To fix this introduce temporary variables for each iteration.

Scaling is not implemented for some type of scalers (QSEED2 and RGB) but
it was unintentionally re-enabled with change below. The remaining
condition in dpu_plane_atomic_check_pipe is not enough because it only
checks for length of scaler block (which is present). This patch adds a
additional check for setup_scaler operation.
