drm/amdgpu/{uvd,vcn}: fetch ring's read_ptr after alloc

2019-06-19T06:00:04Z

commit 517b91f4cde3043d77b2178548473e8545ef07cb upstream. [What] readptr read always returns zero, since most likely these blocks are either power or clock gated. [How] fetch rptr after amdgpu_ring_alloc() which informs the power management code that the block is about to be used and hence the gating is turned off.

drm/amdgpu: further ring test cleanups

2018-11-05T19:21:25Z

Move all error messages from IP specific code into the common helper. This way we now uses the ring name in the messages instead of the index and note which device is affected as well. Also cleanup error handling in the IP specific code and consequently use ETIMEDOUT when the ring test timed out.

drm/amdgpu: Fix vce work queue was not cancelled when suspend

2018-09-27T15:01:20Z

The vce cancel_delayed_work_sync never be called. driver call the function in error path. This caused the A+A suspend hang when runtime pm enebled. As we will visit the smu in the idle queue. this will cause smu hang because the dgpu has been suspend, and the dgpu also will be waked up. As the smu has been hang, so the dgpu resume will failed.
