drm/amdgpu: Need to set moved to true when evict bo
Fix the VMC page fault when the running sequence is as below: 1.amdgpu_gem_create_ioctl 2.ttm_bo_swapout->amdgpu_vm_bo_invalidate, as not called amdgpu_vm_bo_base_init, so won't called list_add_tail(&base->bo_list, &bo->va). Even the bo was evicted, it won't set the bo_base->moved. 3.drm_gem_open_ioctl->amdgpu_vm_bo_base_init, here only called list_move_tail(&base->vm_status, &vm->evicted), but not set the bo_base->moved. 4.amdgpu_vm_bo_map->amdgpu_vm_bo_insert_map, as the bo_base->moved is not set true, the function amdgpu_vm_bo_insert_map will call list_move(&bo_va->base.vm_status, &vm->moved) 5.amdgpu_cs_ioctl won't validate the swapout bo, as it is only in the moved list, not in the evict list. So VMC page fault occurs. Signed-off-by: Emily Deng <Emily.Deng@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
