Rename "ring_mirror_list" to "pending_list",
to describe what something is, not what it does,
how it's used, or how the hardware implements it.
This also abstracts the actual hardware
implementation, i.e. how the low-level driver
communicates with the device it drives, ring, CAM,
etc., shouldn't be exposed to DRM.
The pending_list keeps jobs submitted, which are
out of our control. Usually this means they are
pending execution status in hardware, but the
latter definition is a more general (inclusive)
definition.

|
|
|
|
* Drivers typically issue a reset to recover from GPU hangs, and this
|
|
|
|
* procedure usually follows the following workflow:
|
|
|
|
*
|
|
|
|
* 1. Stop the scheduler using drm_sched_stop(). This will park the
|
|
|
|
* scheduler thread and cancel the timeout work, guaranteeing that
|
|
|
|
* nothing is queued while we reset the hardware queue
|
|
|
|
* 2. Try to gracefully stop non-faulty jobs (optional)
|
|
|
|
* 3. Issue a GPU reset (driver-specific)
|
|
|
|
* 4. Re-submit jobs using drm_sched_resubmit_jobs()
|
|
|
|
* 5. Restart the scheduler using drm_sched_start(). At that point, new
|
|
|
|
* jobs can be queued, and the scheduler thread is unblocked
|
|
|
|
*
|
2021-06-30 14:27:37 +08:00
|
|
|
* Note that some GPUs have distinct hardware queues but need to reset
|
|
|
|
* the GPU globally, which requires extra synchronization between the
|
|
|
|
* timeout handler of the different &drm_gpu_scheduler. One way to
|
|
|
|
* achieve this synchronization is to create an ordered workqueue
|
|
|
|
* (using alloc_ordered_workqueue()) at the driver level, and pass this
|
|
|
|
* queue to drm_sched_init(), to guarantee that timeout handlers are
|
|
|
|
* executed sequentially. The above workflow needs to be slightly
|
|
|
|
* adjusted in that case:
|
|
|
|
*
|
|
|
|
* 1. Stop all schedulers impacted by the reset using drm_sched_stop()
|
|
|
|
* 2. Try to gracefully stop non-faulty jobs on all queues impacted by
|
|
|
|
* the reset (optional)
|
|
|
|
* 3. Issue a GPU reset on all faulty queues (driver-specific)
|
|
|
|
* 4. Re-submit jobs on all schedulers impacted by the reset using
|
|
|
|
* drm_sched_resubmit_jobs()
|
|
|
|
* 5. Restart all schedulers that were stopped in step #1 using
|
|
|
|
* drm_sched_start()
|
|
|
|
*
|

drm/sched: Split drm_sched_job_init
This is a very confusingly named function, because not just does it
init an object, it arms it and provides a point of no return for
pushing a job into the scheduler. It would be nice if that's a bit
clearer in the interface.
But the real reason is that I want to push the dependency tracking
helpers into the scheduler code, and that means drm_sched_job_init
must be called a lot earlier, without arming the job.
v2:
- don't change .gitignore (Steven)
- don't forget v3d (Emma)
v3: Emma noticed that I leak the memory allocated in
drm_sched_job_init if we bail out before the point of no return in
subsequent driver patches. To be able to fix this change
drm_sched_job_cleanup() so it can handle being called both before and
after drm_sched_job_arm().
Also improve the kerneldoc for this.
v4:
- Fix the drm_sched_job_cleanup logic, I inverted the booleans, as
usual (Melissa)
- Christian pointed out that drm_sched_entity_select_rq() also needs
to be moved into drm_sched_job_arm, which made me realize that the
job->id definitely needs to be moved too.
Shuffle things to fit between job_init and job_arm.
v5:
Reshuffle the split between init/arm once more, amdgpu abuses
drm_sched.ready to signal gpu reset failures. Also document this
somewhat. (Christian)
v6:
Rebase on top of the msm drm/sched support. Note that the
drm_sched_job_init() call is completely misplaced, and hence also the
split-out drm_sched_entity_push_job(). I've put in a FIXME which the next
patch will address.
v7: Drop the FIXME in msm, after discussions with Rob I agree it shouldn't
be a problem where it is now.
