drm/scheduler: improve job distribution with multiple queues

2020-01-16T18:37:54+00:00

This patch uses score based logic to select a new rq for better loadbalance between multiple rq/scheds instead of num_jobs. Below are test results after running amdgpu_test from mesa drm Before this patch: sched_name num of many times it got scheduled ========= ================================== sdma0 314 sdma1 32 comp_1.0.0 56 comp_1.0.1 0 comp_1.1.0 0 comp_1.1.1 0 comp_1.2.0 0 comp_1.2.1 0 comp_1.3.0 0 comp_1.3.1 0 After this patch: sched_name num of many times it got scheduled ========= ================================== sdma0 216 sdma1 185 comp_1.0.0 39 comp_1.0.1 9 comp_1.1.0 12 comp_1.1.1 0 comp_1.2.0 12 comp_1.2.1 0 comp_1.3.0 12 comp_1.3.1 0 Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/scheduler: rework entity creation

2019-12-18T21:09:12+00:00

Entity currently keeps a copy of run_queue list and modify it in drm_sched_entity_set_priority(). Entities shouldn't modify run_queue list. Use drm_gpu_scheduler list instead of drm_sched_rq list in drm_sched_entity struct. In this way we can select a runqueue based on entity/ctx's priority for a drm scheduler.

drm/scheduler: Avoid accessing freed bad job.

2019-11-27T15:05:49+00:00

Problem: Due to a race between drm_sched_cleanup_jobs in sched thread and drm_sched_job_timedout in timeout work there is a possiblity that bad job was already freed while still being accessed from the timeout thread. Fix: Instead of just peeking at the bad job in the mirror list remove it from the list under lock and then put it back later when we are garanteed no race with main sched thread is possible which is after the thread is parked. v2: Lock around processing ring_mirror_list in drm_sched_cleanup_jobs. v3: Rebase on top of drm-misc-next. v2 is not needed anymore as drm_sched_get_cleanup_job already has a lock there. v4: Fix comments to relfect latest code in drm-misc.
