drm/nouveau: keep DMA buffers required for suspend/resume

2024-03-01T05:27:04+00:00

Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly.
This is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze.

This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init.

nouveau: report byte usage in VRAM usage.

2024-03-01T05:26:28+00:00

Turns out usage is always in bytes not shifted.

drm/xe: Deny unbinds if uapi ufence pending

2024-02-29T09:39:03+00:00

If user fence was provided for MAP in vm_bind_ioctl
and it has still not been signalled, deny UNMAP of said
vma with EBUSY as long as unsignalled fence exists.

This guarantees that MAP vs UNMAP sequences won't
escape under the radar if we ever want to track the
client's state wrt to completed and accessible MAPs.
By means of intercepting the ufence release signalling.

v2: find ufence with num_fences > 1 (Matt)
v3: careful on clearing vma ufence (Matt)

drm/xe: Expose user fence from xe_sync_entry

2024-02-29T09:39:02+00:00

By allowing getting reference to user fence, we can
control the lifetime outside of sync entries.

This is needed to allow vma to track the associated
user fence that was provided with bind ioctl.

v2: xe_user_fence can be kept opaque (Jani, Matt)
v3: indent fix (Matt)

drm/xe: Use pointers in trace events

2024-02-29T09:39:02+00:00

Commit a0df2cc858c3 ("drm/xe/xe_bo_move: Enhance xe_bo_move trace")
inadvertently reverted commit 8d038f49c1f3 ("drm/xe: Fix cast on trace
variable"), breaking the build on 32bits.

As noted by Ville, there's no point in converting the pointers to u64
and add casts everywhere. In fact, it's better to just use %p and let
the address be hashed. Convert all the cases in xe_trace.h to use
pointers.
