drm/amdgpu: fence wait old rcu slot

2016-04-01T14:08:39Z

since the rcu slot was initialized to be num_hw_submission, if command submission doesn't use scheduler, this limitation will be invalid like uvd test. Signed-off-by: Chunming Zhou Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: switch back to 32bit hw fences v2

2016-03-16T22:00:10Z

We don't need to extend them to 64bits any more, so avoid the extra overhead. v2: update commit message. Signed-off-by: Christian König Acked-by: Alex Deucher Reviewed-by: Chunming Zhou

drm/amdgpu: remove amdgpu_fence_is_signaled

2016-03-16T22:00:01Z

It's just overhead to check the fence value when we signal them directly anyway. Signed-off-by: Christian König Acked-by: Alex Deucher Reviewed-by: Chunming Zhou

drm/amdgpu: drop the extra fence range check v2

2016-03-16T21:59:52Z

Amdgpu doesn't support using scratch registers for fences any more. So we won't see values like 0xdeadbeef as fence value any more. v2: reschedule timer even if no change detected Signed-off-by: Christian König Acked-by: Alex Deucher Reviewed-by: Chunming Zhou

drm/amdgpu: signal fences directly in amdgpu_fence_process

2016-03-16T21:59:41Z

Because of the scheduler we need to signal all fences immediately anyway, so try to avoid the waitqueue overhead. Signed-off-by: Christian König Acked-by: Alex Deucher Reviewed-by: Chunming Zhou

drm/amdgpu: cleanup amdgpu_fence_wait_empty v2

2016-03-16T21:59:32Z

Just wait for last fence instead of waiting for the sequence manually. v2: don't use amdgpu_sched_jobs for the mask Signed-off-by: Christian König Acked-by: Alex Deucher Reviewed-by: Chunming Zhou

drm/amdgpu: keep all fences in an RCU protected array v2

2016-03-16T21:59:22Z

Just keep all HW fences in a RCU protected array as a first step to replace the wait queue. v2: update commit message, move fixes into separate patch. Signed-off-by: Christian König Acked-by: Alex Deucher Reviewed-by: Chunming Zhou

drm/amdgpu: add number of hardware submissions to amdgpu_fence_driver_init_ring

2016-03-16T21:59:12Z

Make this a parameter instead of using the global variable directly. Signed-off-by: Christian König Acked-by: Alex Deucher Reviewed-by: Chunming Zhou

drm/amdgpu: RCU protected amdgpu_fence_release

2016-03-16T21:58:52Z

Fences must be freed RCU protected, otherwise the reservation_object_*_rcu() functions can run into problems. Signed-off-by: Christian König Reviewed-by: Alex Deucher
