drm/amdkfd: Fix an inappropriate error handling in allloc memory of gpu

2021-11-17T10:04:08+00:00

[ Upstream commit 5aeeac6fa38fca450faed9770f75b1470c0e2073 ]

We should unreference a gem object instead of an amdgpu bo here.

drm/amdkfd: fix a potential ttm->sg memory leak

2021-10-13T07:41:58+00:00

[ Upstream commit b072ef1215aca33186e3a10109e872e528a9e516 ]

Memory is allocated for ttm->sg by kmalloc in kfd_mem_dmamap_userptr,
but isn't freed by kfree in kfd_mem_dmaunmap_userptr. Free it!

drm/amdkfd: Allow CPU access for all VRAM BOs

2021-07-13T15:58:38+00:00

The thunk needs to mmap all BOs for CPU access to allow the debugger to
access them. Invisible ones are mapped with PROT_NONE.

drm/amdgpu: remove amdgpu_vm_pt

2021-06-15T21:25:42+00:00

Page table entries are now in embedded in VM BO, so
we do not need struct amdgpu_vm_pt. This patch replaces
struct amdgpu_vm_pt with struct amdgpu_vm_bo_base.

dma-buf: rename and cleanup dma_resv_get_list v2

2021-06-06T09:18:19+00:00

When the comment needs to state explicitly that this is doesn't get a reference
to the object then the function is named rather badly.

Rename the function and use it in even more places.

v2: use dma_resv_shared_list as new name
