drm/amdkfd: Allow CPU access for all VRAM BOs

2021-07-13T15:58:38Z

The thunk needs to mmap all BOs for CPU access to allow the debugger to access them. Invisible ones are mapped with PROT_NONE. Fixes: 71df0368e9b6 ("drm/amdgpu: Implement mmap as GEM object function") Signed-off-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: remove amdgpu_vm_pt

2021-06-15T21:25:42Z

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. Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher
