    48	 * struct drm_sched_entity - A wrapper around a job queue (typically
    49	 * attached to the DRM file_priv).
    50	 *
    51	 * @list: used to append this struct to the list of entities in the
    52	 *        runqueue.
    53	 * @rq: runqueue on which this entity is currently scheduled.
    54	 * @rq_list: a list of run queues on which jobs from this entity can
    55	 *           be scheduled
    56	 * @num_rq_list: number of run queues in the rq_list
    57	 * @rq_lock: lock to modify the runqueue to which this entity belongs.
    58	 * @job_queue: the list of jobs of this entity.
    59	 * @fence_seq: a linearly increasing seqno incremented with each
    60	 *             new &drm_sched_fence which is part of the entity.
    61	 * @fence_context: a unique context for all the fences which belong
    62	 *                 to this entity.
    63	 *                 The &drm_sched_fence.scheduled uses the
    64	 *                 fence_context but &drm_sched_fence.finished uses
    65	 *                 fence_context + 1.
    66	 * @dependency: the dependency fence of the job which is on the top
    67	 *              of the job queue.
    68	 * @cb: callback for the dependency fence above.
    69	 * @guilty: points to ctx's guilty.
    70	 * @fini_status: contains the exit status in case the process was signalled.
    71	 * @last_scheduled: points to the finished fence of the last scheduled job.
    72	 * @last_user: last group leader pushing a job into the entity.
    73	 * @stopped: Marks the enity as removed from rq and destined for termination.
    74	 * @entity_idle: Signals when enityt is not in use
    75	 *
    76	 * Entities will emit jobs in order to their corresponding hardware
    77	 * ring, and the scheduler will alternate between entities based on
    78	 * scheduling policy.
