drm/amdgpu: zero-initialize GART table on allocation
GART TLB is flushed after unmapping but not after mapping. Since
amdgpu_bo_create_kernel() does not zero-initialize the buffer, when a
single PTE is written the TLB may speculatively load other uninitialized
entries from the same cacheline. Those garbage entries can appear valid,
and a subsequent write to another PTE in the same cacheline may cause the
GPU to use a stale garbage PTE from the TLB.
Fix this by calling memset_io() to zero-initialize the GART table with
gart_pte_flags immediately after allocation.
Using AMDGPU_GEM_CREATE_VRAM_CLEARED, SDMA-based clear will not work
since SDMA needs GART to be initialized to work.

drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl()
Two error handling issues exist in xe_exec_queue_create_ioctl():
1. When xe_hw_engine_group_add_exec_queue() fails, the error path jumps
to put_exec_queue which skips xe_exec_queue_kill(). If the VM is in
preempt fence mode, xe_vm_add_compute_exec_queue() has already added
the queue to the VM's compute exec queue list. Skipping the kill
leaves the queue on that list, leading to a dangling pointer after
the queue is freed.
2. When xa_alloc() fails after xe_hw_engine_group_add_exec_queue() has
succeeded, the error path does not call
xe_hw_engine_group_del_exec_queue() to remove the queue from the hw
engine group list. The queue is then freed while still linked into
the hw engine group, causing a use-after-free.
Fix both by:
- Changing the xe_hw_engine_group_add_exec_queue() failure path to jump
to kill_exec_queue so that xe_exec_queue_kill() properly removes the
queue from the VM's compute list.
- Adding a del_hw_engine_group label before kill_exec_queue for the
xa_alloc() failure path, which removes the queue from the hw engine
group before proceeding with the rest of the cleanup.

drm/xe/bo: Fix bo leak on unaligned size validation in xe_bo_init_locked()
When type is ttm_bo_type_device and aligned_size != size, the function

Add xe_bo_free(bo) before returning the error.

drm/xe: Fix potential NULL deref in xe_exec_queue_tlb_inval_last_fence_put_unlocked
xe_exec_queue_tlb_inval_last_fence_put_unlocked() uses q->vm->xe as the
first argument to xe_assert(). This function is called unconditionally
from xe_exec_queue_destroy() for all queues, including kernel queues
that have q->vm == NULL (e.g., queues created during GT init in
xe_gt_record_default_lrcs() with vm=NULL).
While current compilers optimize away the q->vm->xe dereference (even
in CONFIG_DRM_XE_DEBUG=y builds, the compiler pushes the dereference
into the WARN branch that is only taken when the assert condition is
false), the code is semantically incorrect and constitutes undefined
behavior in the C abstract machine for the NULL pointer case.
Use gt_to_xe(q->gt) instead, which is always valid for any exec queue.
This is consistent with how xe_exec_queue_destroy() itself obtains the
xe_device pointer in its own xe_assert at the top of the function.

drm/xe/vf: Use drm mm instead of drm sa for CCS read/write
The suballocator algorithm tracks a hole cursor at the last allocation
and tries to allocate after it. This is optimized for fence-ordered
progress, where older allocations are expected to become reusable first.
In fence-enabled mode, that ordering assumption holds. In fence-disabled
mode, allocations may be freed in arbitrary order, so limiting allocation
to the current hole window can miss valid free space and fail allocations
despite sufficient total space.
Use DRM memory manager instead of sub-allocator to get rid of this issue
as CCS read/write operations do not use fences.

drm/xe/debugfs: Correct printing of register whitelist ranges
The register-save-restore debugfs prints whitelist entries as offset
ranges. E.g.,
REG[0x39319c-0x39319f]: allow read access
for a single dword-sized register. However the GENMASK value used to
set the lower bits to '1' for the upper bound of the whitelist range
incorrectly included one more bit than it should have, causing the
whitelist ranges to sometimes appear twice as large as they really were.
For example,
REG[0x6210-0x6217]: allow rw access
was also intended to be a single dword-sized register whitelist (with a
range 0x6210-0x6213) but was printed incorrectly as a qword-sized range
because one too many bits was flipped on. Similar 'off by one' logic
was applied when printing 4-dword register ranges and 64-dword register
ranges as well.
Correct the GENMASK logic to print these ranges in debugfs correctly.
No impact outside of correcting the misleading debugfs output.

drm/amd/display: Update MCIF_ADDR macro to address IGT DWB regression
[Why]
A previous warning-fix commit updated type casts in the DCN3
mmhubbub code but missed updating the MCIF_ADDR macro to the
correct, fully parenthesized and casted version. This caused
a regression during DWB tests, where address values could be
misinterpreted, potentially leading to incorrect hardware
programming.
[How]
Updated the MCIF_ADDR macro in dcn30_mmhubbub.c to use the
proper parenthesization and type casting, ensuring correct
address handling. Removed redundant casts from REG_UPDATE
calls for improved clarity and consistency with current
coding standards.

drm/udl: Increase GET_URB_TIMEOUT
[WHY]
A situation has occurred where udl_handle_damage() executed successfully
and the kernel log appears normal, but the display fails to show any output.
This is because the call to udl_get_urb() in udl_crtc_helper_atomic_enable()
failed without generating any error message.
[HOW]
1. Increase timeout of getting urb.
2. Add error messages when calling udl_get_urb() failed in
udl_crtc_helper_atomic_enable().

drm/gem: Fix inconsistent plane dimension calculation in drm_gem_fb_init_with_funcs()
drm_gem_fb_init_with_funcs() computes sub-sampled plane dimensions
using plain integer division:
unsigned int width = mode_cmd->width / (i ? info->hsub : 1);
unsigned int height = mode_cmd->height / (i ? info->vsub : 1);
However, the ioctl-level framebuffer_check() in drm_framebuffer.c uses
drm_format_info_plane_width/height() which round up dimensions via
DIV_ROUND_UP(). This inconsistency corrupts the subsequent GEM object
size check for certain pixel format and dimension combinations.
For example, with NV12 (vsub=2) and a 1-pixel-tall framebuffer the
GEM size validation path sees height=0 instead of height=1. The
expression (height - 1) then wraps to UINT_MAX as an unsigned int,
causing min_size to overflow and wrap back to a small value. A tiny
GEM object therefore passes the size guard, yet when the GPU accesses
the chroma plane it will read or write memory beyond the object's
bounds.
Fix by replacing the open-coded divisions with drm_format_info_plane_width()
and drm_format_info_plane_height(), which use DIV_ROUND_UP() and match
the calculation already used in framebuffer_check().

- Fix accounting of persistent ring buffer rewind
On boot up, the head page is moved back to the earliest point of the
saved ring buffer. This is because the ring buffer being read by user
space on a crash may not save the part it read. Rewinding the head
page back to the earliest saved position helps keep those events from
being lost.
The number of events is also read during boot up and displayed in the
stats file in the tracefs directory. It's also used for other
accounting as well. On boot up, the "reader page" is accounted for
but a rewind may put it back into the buffer and then the reader page
may be accounted for again.
Save off the original reader page and skip accounting it when
scanning the pages in the ring buffer.

"Bugfixes:
- Fix handling of ENOSPC so that if we have to resend writes, they
are written synchronously
- SUNRPC RDMA transport fixes from Chuck
- Several fixes for delegated timestamps in NFSv4.2
- Failure to obtain a directory delegation should not cause stat() to
fail with NFSv4
- Rename was failing to update timestamps when a directory delegation
is held on NFSv4
- Ensure we check rsize/wsize after crossing a NFSv4 filesystem
boundary
- NFSv4/pnfs:
- If the server is down, retry the layout returns on reboot
- Fallback to MDS could result in a short write being incorrectly
logged
Cleanups:
- Use memcpy_and_pad in decode_fh"
