2017-10-09drm/amdgpu: implement ring set_priority for gfx_v8 compute v9Andres Rodriguez
Programming CP_HQD_QUEUE_PRIORITY enables a queue to take priority over other queues on the same pipe. Multiple queues on a pipe are timesliced so this gives us full precedence over other queues. Programming CP_HQD_PIPE_PRIORITY changes the SPI_ARB_PRIORITY of the wave as follows: 0x2: CS_H 0x1: CS_M 0x0: CS_L The SPI block will then dispatch work according to the policy set by SPI_ARB_PRIORITY. In the current policy CS_H is higher priority than gfx. In order to prevent getting stuck in loops of resources bouncing between GFX and high priority compute and introducing further latency, we statically reserve a portion of the pipe. v2: fix srbm_select to ring->queue and use ring->funcs->type v3: use AMD_SCHED_PRIORITY_* instead of AMDGPU_CTX_PRIORITY_* v4: switch int to enum amd_sched_priority v5: corresponding changes for srbm_lock v6: change CU reservation to PIPE_PERCENT allocation v7: use kiq instead of MMIO v8: back to MMIO, and make the implementation sleep safe. v9: corresponding changes for splitting HIGH into _HW/_SW Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andres Rodriguez <andresx7@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
