drm/amdgpu: allocate entities on demand

2020-01-30T22:15:42Z

Currently we pre-allocate entities and fences for all the HW IPs on context creation and some of which are might never be used. This patch tries to resolve entity/fences wastage by creating entity only when needed. v2: allocate memory for entity and fences together Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: individualize fence allocation per entity

2020-01-22T21:55:27Z

Allocate fences for each entity and remove ctx->fences reference as fences should be bound to amdgpu_ctx_entity instead amdgpu_ctx. Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: fix ctx init failure for asics without gfx ring

2019-12-23T19:56:09Z

This workaround does not affect other asics because amdgpu only need expose one gfx sched to user for now. Signed-off-by: Le Ma Reviewed-by: Nirmoy Das Signed-off-by: Alex Deucher

amd/amdgpu: add sched array to IPs with multiple run-queues

2019-12-18T21:09:12Z

This sched array can be passed on to entity creation routine instead of manually creating such sched array on every context creation. v2: squash in missing break fix Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/scheduler: rework entity creation

2019-12-18T21:09:12Z

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/amdgpu: dont schedule jobs while in reset

2019-11-06T19:20:24Z

[Why] doing kthread_park()/unpark() from drm_sched_entity_fini while GPU reset is in progress defeats all the purpose of drm_sched_stop->kthread_park. If drm_sched_entity_fini->kthread_unpark() happens AFTER drm_sched_stop->kthread_park nothing prevents from another (third) thread to keep submitting job to HW which will be picked up by the unparked scheduler thread and try to submit to HW but fail because the HW ring is deactivated.

drm/amdgpu: correct ras error count type

Use unsigned long type for the same ras count variable. This will avoid overflow on 64 bit system. Signed-off-by: Guchun Chen Reviewed-by: Tao Zhou Signed-off-by: Alex Deucher
