drm/amd/amdgpu: Enable high priority gfx queue

2022-06-06T18:41:25Z

Starting from SIENNA CICHLID asic supports two gfx pipes, enabling two graphics queues, 1 on each pipe, pipe0 queue0 would be the normal piority queue and pipe1 queue0 would be the high priority queue Only one queue per pipe is visble to SPI, SPI looks at the priority value assigned to CP_GFX_HQD_QUEUE_PRIORITY from each of the queue's HQD/MQD. Create contexts applying AMDGPU_CTX_PRIORITY_HIGH which submits job to the high priority queue on GFX pipe1. There would be starvation of LP workload if HP workload is always available. v2: - remove unnecessary check(Nirmoy) - make pipe1 hardware support a separate patch(Nirmoy) - remove duplicate code(Shashank) - add CSA support for second gfx pipe(Alex) v3(Christian): - fix incorrect indentation - merge COMPUTE and GFX switch cases as both calls the same function. v4: - rebase w/ latest code base Signed-off-by: Arunpravin Paneer Selvam Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Move scheduler init to after XGMI is ready

2022-02-09T17:15:04Z

Before we initialize schedulers we must know which reset domain are we in - for single device there iis a single domain per device and so single wq per device. For XGMI the reset domain spans the entire XGMI hive and so the reset wq is per hive.
