From dbe48d030b285a1305a874bee523681709fba162 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 17 Aug 2021 10:49:16 +0200 Subject: drm/sched: Split drm_sched_job_init MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
