drm/scheduler: Remove priority macro INVALID (v2)

2020-08-18T22:20:26+00:00

Remove DRM_SCHED_PRIORITY_INVALID. We no longer carry around an invalid priority and cut it off at the source. Backwards compatibility behaviour of AMDGPU CTX IOCTL passing in garbage for context priority from user space and then mapping that to DRM_SCHED_PRIORITY_NORMAL is preserved. v2: Revert "res" --> "r" and "prio" --> "priority".

drm/scheduler: Scheduler priority fixes (v2)

2020-08-18T22:20:17+00:00

Remove DRM_SCHED_PRIORITY_LOW, as it was used in only one place. Rename and separate by a line DRM_SCHED_PRIORITY_MAX to DRM_SCHED_PRIORITY_COUNT as it represents a (total) count of said priorities and it is used as such in loops throughout the code. (0-based indexing is the the count number.) Remove redundant word HIGH in priority names, and rename *KERNEL* to *HIGH*, as it really means that, high. v2: Add back KERNEL and remove SW and HW, in lieu of a single HIGH between NORMAL and KERNEL.

drm/scheduler: improve job distribution with multiple queues

2020-06-26T12:16:29+00:00

This patch uses score to select a new drm scheduler for better loadbalance between multiple drm schedulers instead of num_jobs. Below are test results after running amdgpu_test for ~10 times. Before this patch: sched_name num of many times it got schedule ========= ================================== sdma0 1463 sdma1 198 comp_1.0.1 280 After this patch: sched_name num of many times it got schedule ========= ================================== sdma0 925 sdma1 928 comp_1.0.1 177 comp_1.1.1 44 comp_1.2.1 43 comp_1.3.1 44 Signed-off-by: Nirmoy Das Reviewed-by: Christian König Link: https://patchwork.freedesktop.org/patch/373000/ Signed-off-by: Christian König

drm/sched: implement and export drm_sched_pick_best

2020-03-16T20:21:32+00:00

Remove drm_sched_entity_get_free_sched() and use the logic of picking the least loaded drm scheduler from a drm scheduler list to implement drm_sched_pick_best(). This patch also exports drm_sched_pick_best() so that it can be utilized by other drm drivers. Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/scheduler: implement a function to modify sched list

2020-03-09T17:51:35+00:00

Implement drm_sched_entity_modify_sched() which modifies existing sched_list with a different one. This is going to be helpful when userspace changes priority of a ctx/entity then the driver can switch to the corresponding HW scheduler list for that priority.
