Detailed Description

struct drm_sched_job - A job to be run by an entity.

@queue_node: used to append this struct to the queue of jobs in an entity. @list: a job participates in a "pending" and "done" lists. @sched: the scheduler instance on which this job is scheduled. @s_fence: contains the fences for the scheduling of job. @finish_cb: the callback for the finished fence. @credits: the number of credits this job contributes to the scheduler @work: Helper to reschedule job kill to different context. @karma: increment on every hang caused by this job. If this exceeds the hang limit of the scheduler then the job is marked guilty and will not be scheduled further. @s_priority: the priority of the job. @entity: the entity to which this job belongs. @cb: the callback for the parent fence in s_fence.

A job is created by the driver using drm_sched_job_init(), and should call drm_sched_entity_push_job() once it wants the scheduler to schedule the job.
