drm/sched: Set error to s_fence if HW job submission failed.

2019-10-25T20:50:11+00:00

Problem: When run_job fails and HW fence returned is NULL we still signal the s_fence to avoid hangs but the user has no way of knowing if the actual HW job was ran and finished. Fix: Allow .run_job implementations to return ERR_PTR in the fence pointer returned and then set this error for s_fence->finished fence so whoever wait on this fence can inspect the signaled fence for an error.

drm: Don't free jobs in wait_event_interruptible()

2019-10-25T11:47:58+00:00

drm_sched_cleanup_jobs() attempts to free finished jobs, however because it is called as the condition of wait_event_interruptible() it must not sleep. Unfortunately some free callbacks (notably for Panfrost) do sleep. Instead let's rename drm_sched_cleanup_jobs() to drm_sched_get_cleanup_job() and simply return a job for processing if there is one. The caller can then call the free_job() callback outside the wait_event_interruptible() where sleeping is possible before re-checking and returning to sleep if necessary.

drm/scheduler: use job count instead of peek

2019-08-15T15:52:10+00:00

The spsc_queue_peek function is accessing queue->head which belongs to the consumer thread and shouldn't be accessed by the producer This is fixing a rare race condition when destroying entities.
