drm/amdgpu: rework sched_list generation

2020-04-09T14:43:14Z

Generate HW IP's sched_list in amdgpu_ring_init() instead of amdgpu_ctx.c. This makes amdgpu_ctx_init_compute_sched(), ring.has_high_prio and amdgpu_ctx_init_sched() unnecessary. This patch also stores sched_list for all HW IPs in one big array in struct amdgpu_device which makes amdgpu_ctx_init_entity() much more leaner. v2: fix a coding style issue do not use drm hw_ip const to populate amdgpu_ring_type enum v3: remove ctx reference and move sched array and num_sched to a struct use num_scheds to detect uninitialized scheduler list v4: use array_index_nospec for user space controlled variables fix possible checkpatch.pl warnings Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: disable gpu_sched load balancer for vcn jobs

2020-03-16T20:21:32Z

VCN HW doesn't support dynamic load balance on multiple instances for a context. This patch initializes VNC entities with only one drm_gpu_scheduler picked by drm_sched_pick_best(). Picking a drm_gpu_scheduler using drm_sched_pick_best() ensures that we do load balance among multiple contexts but not among multiple jobs in a context.

drm/amdgpu: set compute queue priority at mqd_init

2020-03-09T17:51:24Z

We were changing compute ring priority while rings were being used before every job submission which is not recommended. This patch sets compute queue priority at mqd initialization for gfx8, gfx9 and gfx10. Policy: make queue 0 of each pipe as high priority compute queue High/normal priority compute sched lists are generated from set of high/normal priority compute queues. At context creation, entity of compute queue get a sched list from high or normal priority depending on ctx->priority Signed-off-by: Nirmoy Das Acked-by: Alex Deucher Acked-by: Christian König Signed-off-by: Alex Deucher

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
