drm/amd: Make fence wait in suballocator uninterruptible

2023-09-01T13:12:07+00:00

Commit c103a23f2f29 ("drm/amd: Convert amdgpu to use suballocation helper.") made the fence wait in amdgpu_sa_bo_new() interruptible but there is no code to handle an interrupt. This caused the kernel to randomly explode in high-VRAM-pressure situations so make it uninterruptible again.

drm/amd: Convert amdgpu to use suballocation helper.

2023-03-01T16:18:19+00:00

Now that we have a generic suballocation helper, Use it in amdgpu. For lines that get moved or changed, also fix up pre-existing style issues.

dma-buf: make fence sequence numbers 64 bit v2

2018-12-07T11:44:16+00:00

For a lot of use cases we need 64bit sequence numbers. Currently drivers overload the dma_fence structure to store the additional bits. Stop doing that and make the sequence number in the dma_fence always 64bit. For compatibility with hardware which can do only 32bit sequences the comparisons in __dma_fence_is_later only takes the lower 32bits as significant when the upper 32bits are all zero. v2: change the logic in __dma_fence_is_later Signed-off-by: Christian König Reviewed-by: Chunming Zhou Link: https://patchwork.freedesktop.org/patch/266927/

drm/amdgpu: Initialize fences array entries in amdgpu_sa_bo_next_hole

2018-09-14T14:37:17+00:00

The entries were only initialized once in amdgpu_sa_bo_new. If a fence wasn't signalled yet in the first amdgpu_sa_bo_next_hole call, but then got signalled before a later amdgpu_sa_bo_next_hole call, it could destroy the fence but leave its pointer in the array, resulting in use-after-free in amdgpu_sa_bo_new.

drm/amdgpu: cleanup SA inti and fini(v2)

2018-02-28T19:18:07+00:00

should use bo_create_kernel instead of split to two function that create and pin the SA bo issue: before this patch, there are DMAR read error in host side when running SRIOV test, the DMAR address dropped in the range of SA bo. fix: after this cleanups of SA init and fini, above DMAR eror gone. v2: keep sa_bo's fini instead of suspend, to keep reporting error Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

Some of these paths probably cannot be interrupted by a signal anyway. Those that can would fail to clean up things if they actually got interrupted. Reviewed-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher
