We no longer have sched parameter so remove its description as well Signed-off-by: Nayan Deshmukh Signed-off-by: Alex Deucher

drm/scheduler: fix timeout worker setup for out of order job completions

2018-08-06T20:58:00+00:00

drm_sched_job_finish() is a work item scheduled for each finished job on a unbound system workqueue. This means the workers can execute out of order with regard to the real hardware job completions. If this happens queueing a timeout worker for the first job on the ring mirror list is wrong, as this may be a job which has already finished executing. Fix this by reorganizing the code to always queue the worker for the next job on the list, if this job hasn't finished yet. This is robust against a potential reordering of the finish workers. Also move out the timeout worker cancelling, so that we don't need to take the job list lock twice. As a small optimization list_del is used to remove the job from the ring mirror list, as there is no need to reinit the list head in the job we are about to free.

drm/scheduler: stop setting rq to NULL

2018-07-31T21:58:20+00:00

We removed the redundancy of having an extra scheduler field, so we can't set the rq to NULL any more or otherwise won't know which scheduler to use for the cleanup. Just remove the entity from the scheduling list instead. Signed-off-by: Christian König Acked-by: Nayan Deshmukh Bug: https://bugs.freedesktop.org/show_bug.cgi?id=107367 Signed-off-by: Alex Deucher

drm/scheduler: only kill entity if last user is killed v2

2018-07-31T21:58:20+00:00

Note which task is using the entity and only kill it if the last user of the entity is killed. This should prevent problems when entities are leaked to child processes. v2: add missing kernel doc Signed-off-by: Christian König Reviewed-by: Andrey Grodzovsky Acked-by: Nayan Deshmukh Signed-off-by: Alex Deucher

drm/sched: remove unneeded -Iinclude/drm compiler flag

2018-07-31T21:58:16+00:00

I refactored the include directives under include/drm/ some time ago. This flag is unneeded. Signed-off-by: Masahiro Yamada Reviewed-by: Christian König Acked-by: Nayan Deshmukh Signed-off-by: Alex Deucher

drm/scheduler: remove sched field from the entity

2018-07-25T20:06:26+00:00

The scheduler of the entity is decided by the run queue on which it is queued. This patch avoids us the effort required to maintain a sync between rq and sched field when we start shifting entites among different rqs.

drm/scheduler: modify API to avoid redundancy

drm/scheduler: add NULL pointer check for run queue (v2)

2018-07-16T21:11:48+00:00

To check rq pointer before adding entity into it. That avoids NULL pointer access in some case. v2: move the check to caller Suggested-by: Christian König Signed-off-by: Junwei Zhang Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/scheduler: modify args of drm_sched_entity_init

drm/scheduler: add a pointer to scheduler in the rq

2018-07-13T19:45:58+00:00

This patch is in preparation for a better load balancing in scheduler. It allows us to associate entities with the run queues instead of binding them to a scheduler. Signed-off-by: Nayan Deshmukh Reviewed-by: Christian König Acked-by: Eric Anholt Signed-off-by: Alex Deucher
