2021-09-01drm/amdgpu: rework context priority handlingNirmoy Das
To get a hardware queue priority for a context, we are currently mapping AMDGPU_CTX_PRIORITY_* to DRM_SCHED_PRIORITY_* and then to hardware queue priority, which is not the right way to do that as DRM_SCHED_PRIORITY_* is software scheduler's priority and it is independent from a hardware queue priority. Use userspace provided context priority, AMDGPU_CTX_PRIORITY_* to map a context to proper hardware queue priority.

2021-05-13drm/amdgpu: fix fence calculation (v2)David M Nieto
The proper metric for fence utilization over several contexts is an harmonic mean, but such calculation is prohibitive in kernel space, so the code approximates it. Because the approximation diverges when one context has a very small ratio compared with the other context, this change filter out ratios smaller that 0.01% v2: make the fence calculation static and initialize variables within that function v3: Fix warnings (Alex) Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: David M Nieto <david.nieto@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210513174539.27409-2-david.nieto@amd.com

2020-04-09drm/amdgpu: rework sched_list generationNirmoy Das
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 <nirmoy.das@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-01-30drm/amdgpu: allocate entities on demandNirmoy Das
Currently we pre-allocate entities and fences for all the HW IPs on context creation and some of which are might never be used.
