drm/amdgpu: Set vmbo destroy after pt bo is created

2022-10-06T16:08:09+00:00

Under VRAM usage pression, map to GPU may fail to create pt bo and vmbo->shadow_list is not initialized, then ttm_bo_release calling amdgpu_bo_vm_destroy to access vmbo->shadow_list generates below dmesg and NULL pointer access backtrace: Set vmbo destroy callback to amdgpu_bo_vm_destroy only after creating pt bo successfully, otherwise use default callback amdgpu_bo_destroy. amdgpu: amdgpu_vm_bo_update failed amdgpu: update_gpuvm_pte() failed amdgpu: Failed to map bo to gpuvm amdgpu 0000:43:00.0: amdgpu: Failed to map peer:0000:43:00.0 mem_domain:2 BUG: kernel NULL pointer dereference, address: RIP: 0010:amdgpu_bo_vm_destroy+0x4d/0x80 [amdgpu] Call Trace: ttm_bo_release+0x207/0x320 [amdttm] amdttm_bo_init_reserved+0x1d6/0x210 [amdttm] amdgpu_bo_create+0x1ba/0x520 [amdgpu] amdgpu_bo_create_vm+0x3a/0x80 [amdgpu] amdgpu_vm_pt_create+0xde/0x270 [amdgpu] amdgpu_vm_ptes_update+0x63b/0x710 [amdgpu] amdgpu_vm_update_range+0x2e7/0x6e0 [amdgpu] amdgpu_vm_bo_update+0x2bd/0x600 [amdgpu] update_gpuvm_pte+0x160/0x420 [amdgpu] amdgpu_amdkfd_gpuvm_map_memory_to_gpu+0x313/0x1130 [amdgpu] kfd_ioctl_map_memory_to_gpu+0x115/0x390 [amdgpu] kfd_ioctl+0x24a/0x5b0 [amdgpu] Signed-off-by: Philip Yang Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Check BO's requested pinning domains against its preferred_domains

2022-07-14T00:56:44+00:00

When pinning a buffer, we should check to see if there are any additional restrictions imposed by bo->preferred_domains. This will prevent the BO from being moved to an invalid domain when pinning. For example, this can happen if the user requests to create a BO in GTT domain for display scanout. amdgpu_dm will allow pinning to either VRAM or GTT domains, since DCN can scanout from either or. However, in amdgpu_bo_pin_restricted(), pinning to VRAM is preferred if there is adequate carveout. This can lead to pinning to VRAM despite the user requesting GTT placement for the BO. v2: Allow the kernel to override the domain, which can happen when exporting a BO to a V4L camera (for example).

drm/ttm: rename and cleanup ttm_bo_init

2022-07-11T08:53:13+00:00

Rename ttm_bo_init to ttm_bo_init_validate since that better matches what the function is actually doing. Remove the unused size parameter, move the function's kerneldoc to the implementation and cleanup the whole error handling.

drm/amdgpu: add AMDGPU_GEM_CREATE_DISCARDABLE

2022-05-26T18:56:34+00:00

Add a AMDGPU_GEM_CREATE_DISCARDABLE flag to note that the content of a BO doesn't needs to be preserved during eviction. KFD was already using a similar functionality for SVM BOs so replace the internal flag with the new UAPI.
