UAPI Changes:
- Only allow a single user-fence per exec / bind.
The reason for this clarification fix is a limitation in the implementation
which can be lifted moving forward, if needed.
Driver Changes:
- A crash fix
- A fix for an assert due to missing mem_acces ref
- Only allow a single user-fence per exec / bind.
- Some sparse warning fixes
- Two fixes for compilation failures on various odd
combinations of gcc / arch pointed out on LKML.
- Fix a fragile partial allocation pointed out on LKML.
Cross-driver Change:
- A sysfs ABI documentation warning fix
This also touches i915 and is acked by i915 maintainers.

drm/xe/vm: Subclass userptr vmas
The construct allocating only parts of the vma structure when
the userptr part is not needed is very fragile. A developer could
add additional fields below the userptr part, and the code could
easily attempt to access the userptr part even if its not persent.
So introduce xe_userptr_vma which subclasses struct xe_vma the
proper way, and accordingly modify a couple of interfaces.
This should also help if adding userptr helpers to drm_gpuvm.
v2:
- Fix documentation of to_userptr_vma() (Matthew Brost)
- Fix allocation and freeing of vmas to clearer distinguish

drm/amdgpu: remove asymmetrical irq disabling in vcn 4.0.5 suspend

Beside, current set function callbacks are empty with no real effect.
drm/amd/display: Fix buffer overflow in 'get_host_router_total_dp_tunnel_bw()'
The error message buffer overflow 'dc->links' 12 <= 12 suggests that the
code is trying to access an element of the dc->links array that is
beyond its bounds. In C, arrays are zero-indexed, so an array with 12
elements has valid indices from 0 to 11. Trying to access dc->links[12]
would be an attempt to access the 13th element of a 12-element array,
which is a buffer overflow.
To fix this, ensure that the loop does not go beyond the last valid
index when accessing dc->links[i + 1] by subtracting 1 from the loop
condition.
This would ensure that i + 1 is always a valid index in the array.
drm/amd/display: Add NULL check for kzalloc in 'amdgpu_dm_atomic_commit_tail()'
Add a NULL check for the kzalloc call that allocates memory for
dummy_updates in the amdgpu_dm_atomic_commit_tail function. Previously,
if kzalloc failed to allocate memory and returned NULL, the code would
attempt to use the NULL pointer.
The fix is to check if kzalloc returns NULL, and if so, log an error
message and skip the rest of the current loop iteration with the
continue statement. This prevents the code from attempting to use the
NULL pointer.
This warning info was printed after applying the patch
"drm/sched: Convert drm scheduler to use a work queue rather than kthread".
The root cause is that amdgpu driver tries to use the uninitialized
work_struct in the struct drm_gpu_scheduler

amdgpu_ring.c (Alex)

MAX_SURFACES is per stream, while MAX_PLANES is per asic. The

MAX_PLANES should be used as the array size. Using MAX_SURFACES causes
array overflow when there are more than 3 planes.

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

underflow issues (underflow occurs when phantom pipe is turned on for some
Sub-Viewport configs).

Increasing DCFCLK by raising the min_dcfclk_mhz

dma-buf: heaps: Don't track CMA dma-buf pages under RssFile
DMA buffers allocated from the CMA dma-buf heap get counted under
RssFile for processes that map them and trigger page faults. In
addition to the incorrect accounting reported to userspace, reclaim
behavior was influenced by the MM_FILEPAGES counter until linux 6.8, but
this memory is not reclaimable. [1] Change the CMA dma-buf heap to set
VM_PFNMAP on the VMA so MM does not poke at the memory managed by this
dma-buf heap, and use vmf_insert_pfn to correct the RSS accounting.
The system dma-buf heap does not suffer from this issue since
remap_pfn_range is used during the mmap of the buffer, which also sets
VM_PFNMAP on the VMA.

This commit causes some regressions in desktop usage, this will

drm: bridge: samsung-dsim: Don't use FORCE_STOP_STATE
The FORCE_STOP_STATE bit is unsuitable to force the DSI link into LP-11
mode. It seems the bridge internally queues DSI packets and when the
FORCE_STOP_STATE bit is cleared, they are sent in close succession
without any useful timing (this also means that the DSI lanes won't go
into LP-11 mode). The length of this gibberish varies between 1ms and
5ms. This sometimes breaks an attached bridge (TI SN65DSI84 in this
case). In our case, the bridge will fail in about 1 per 500 reboots.
The FORCE_STOP_STATE handling was introduced to have the DSI lanes in
LP-11 state during the .pre_enable phase. But as it turns out, none of
this is needed at all. Between samsung_dsim_init() and
samsung_dsim_set_display_enable() the lanes are already in LP-11 mode.
The code as it was before commit 20c827683de0 ("drm: bridge:
samsung-dsim: Fix init during host transfer") and 0c14d3130654 ("drm:
bridge: samsung-dsim: Fix i.MX8M enable flow to meet spec") was correct
in this regard.
This patch basically reverts both commits. It was tested on an i.MX8M
SoC with an SN65DSI84 bridge. The signals were probed and the DSI
packets were decoded during initialization and link start-up. After this
patch the first DSI packet on the link is a VSYNC packet and the timing
is correct.
Command mode between .pre_enable and .enable was also briefly tested by
a quick hack. There was no DSI link partner which would have responded,
but it was made sure the DSI packet was send on the link. As a side
note, the command mode seems to just work in HS mode. I couldn't find
that the bridge will handle commands in LP mode.
