drm/amdgpu: stop adding VM updates fences to the resv obj

2019-12-09T22:02:15Z

Don't add the VM update fences to the resv object and remove the handling to stop implicitely syncing to them. Ongoing updates prevent page tables from being evicted and we manually block for all updates to complete before releasing PDs and PTS. This way we can do updates even without the resv obj locked.

drm/amdgpu: Add KFD eviction fence

2018-02-07T01:32:35Z

This fence is used by KFD to keep memory resident while user mode queues are enabled. Trying to evict memory will trigger the enable_signaling callback, which starts a KFD eviction, which involves preempting user mode queues before signaling the fence. There is one such fence per process. v2: * Grab a reference to mm_struct * Dereference fence after NULL check * Simplify fence release, no need to signal without anyone waiting * Added signed-off-by Harish, who is the original author of this code v3: * update MAINTAINERS file * change amd_kfd_ prefix to amdkfd_ * remove useless initialization of variable to NULL v4: * set amdkfd_fence_ops to be static * Suggested by: Fengguang Wu Signed-off-by: Harish Kasiviswanathan Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm: move amd_gpu_scheduler into common location

2017-12-07T16:51:56Z

This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.
