      are valid and update seq num
   2. amdgpu_hmm_range_free: Clean up the hmm range
      and pfn memory.

b. amdgpu_ttm_tt_get_user_pages_done and
   amdgpu_ttm_tt_discard_user_pages are similar function so remove
   discard and directly use amdgpu_hmm_range_free to clean up the

0ef930e1fa drm/amdgpu: fix hung reset queue array memory allocation
By design the MES will return an array result that is twice the number
of hung doorbells it can report.

i.e. if up k reported doorbells are supported, then the
second half of the array, also of length k, holds the HQD information
(type/queue/pipe) where queue 1 corresponds to index 0 and k,
queue 2 corresponds to index 1 and k + 1 etc ...

The driver will use the HDQ info to target queue/pipe reset for
hardware scheduled user compute queues.

883f309add drm/amdgpu: Fix NULL pointer dereference in VRAM logic for APU devices
Previously, APU platforms (and other scenarios with uninitialized VRAM managers)
triggered a NULL pointer dereference in `ttm_resource_manager_usage()`. The root
cause is not that the `struct ttm_resource_manager *man` pointer itself is NULL,
but that `man->bdev` (the backing device pointer within the manager) remains
uninitialized (NULL) on APUs—since APUs lack dedicated VRAM and do not fully
set up VRAM manager structures. When `ttm_resource_manager_usage()` attempts to
acquire `man->bdev->lru_lock`, it dereferences the NULL `man->bdev`, leading to
a kernel OOPS.

1. **amdgpu_cs.c**: Extend the existing bandwidth control check in
   `amdgpu_cs_get_threshold_for_moves()` to include a check for
   `ttm_resource_manager_used()`. If the manager is not used (uninitialized
   `bdev`), return 0 for migration thresholds immediately—skipping VRAM-specific
   logic that would trigger the NULL dereference.

2. **amdgpu_kms.c**: Update the `AMDGPU_INFO_VRAM_USAGE` ioctl and memory info
   reporting to use a conditional: if the manager is used, return the real VRAM
   usage; otherwise, return 0. This avoids accessing `man->bdev` when it is
   NULL.

3. **amdgpu_virt.c**: Modify the vf2pf (virtual function to physical function)
   data write path. Use `ttm_resource_manager_used()` to check validity: if the
   manager is usable, calculate `fb_usage` from VRAM usage; otherwise, set
   `fb_usage` to 0 (APUs have no discrete framebuffer to report).

This approach is more robust than APU-specific checks because it:
- Works for all scenarios where the VRAM manager is uninitialized (not just APUs),
- Aligns with TTM's design by using its native helper function,
- Preserves correct behavior for discrete GPUs (which have fully initialized
  `man->bdev` and pass the `ttm_resource_manager_used()` check).

v4: use ttm_resource_manager_used(&adev->mman.vram_mgr.manager) instead of checking the adev->gmc.is_app_apu flag (Christian)

6df8e84aa6 drm/amdgpu: use atomic functions with memory barriers for vm fault info
The atomic variable vm_fault_info_updated is used to synchronize access to
adev->gmc.vm_fault_info between the interrupt handler and
get_vm_fault_info().

The default atomic functions like atomic_set() and atomic_read() do not
provide memory barriers. This allows for CPU instruction reordering,
meaning the memory accesses to vm_fault_info and the vm_fault_info_updated
flag are not guaranteed to occur in the intended order. This creates a
race condition that can lead to inconsistent or stale data being used.

The previous implementation, which used an explicit mb(), was incomplete
and inefficient. It failed to account for all potential CPU reorderings,
such as the access of vm_fault_info being reordered before the atomic_read
of the flag. This approach is also more verbose and less performant than
using the proper atomic functions with acquire/release semantics.

Fix this by switching to atomic_set_release() and atomic_read_acquire().
These functions provide the necessary acquire and release semantics,
which act as memory barriers to ensure the correct order of operations.
It is also more efficient and idiomatic than using explicit full memory
barriers.

8f74c70be5 drm/amdgpu: block CE CS if not explicitely allowed by module option
The Constant Engine found on gfx6-gfx10 HW has been a notorious source of
problems.

RADV never used it in the first place, radeonsi only used it for a few
releases around 2017 for gfx6-gfx9 before dropping support for it as
well.

While investigating another problem I just recently found that submitting
to the CE seems to be completely broken on gfx9 for quite a while.

Since nobody complained about that problem it most likely means that
nobody is using any of the affected radeonsi versions on current Linux
kernels any more.

So to potentially phase out the support for the CE and eliminate another
source of problems block submitting CE IBs unless it is enabled again
using a debug flag.

e4bea91958 drm/nouveau: fix bad ret code in nouveau_bo_move_prep
In `nouveau_bo_move_prep`, if `nouveau_mem_map` fails, an error code
should be returned. Currently, it returns zero even if vmm addr is not
correctly mapped.

d07e142641 drm/amd/display: Incorrect Mirror Cositing
[WHY]
hinit/vinit are incorrect in the case of mirroring.

[HOW]
Cositing sign must be flipped when image is mirrored in the vertical
or horizontal direction.

2e97663760 drm/amdgpu: Report individual reset error
If reinitialization of one of the GPUs fails after reset, it logs
failure on all subsequent GPUs eventhough they have resumed
successfully.

A sample log where only device at 0000:95:00.0 had a failure -

	amdgpu 0000:15:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:65:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:75:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:85:00.0: amdgpu: GPU reset(19) succeeded!
	amdgpu 0000:95:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:e5:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:f5:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:05:00.0: amdgpu: GPU reset(19) failed
	amdgpu 0000:15:00.0: amdgpu: GPU reset end with ret = -5

To avoid confusion, report the error for each device
separately and return the first error as the overall result.
