Subject: [PATCH v2 05/11] drm/lima: use scheduler dependency tracking
Date: Fri,  2 Jul 2021 23:38:09 +0200	[thread overview]
Message-ID: <20210702213815.2249499-6-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20210702213815.2249499-1-daniel.vetter@ffwll.ch>

Nothing special going on here.

Aside reviewing the code, it seems like drm_sched_job_arm() should be
moved into lima_sched_context_queue_task and put under some mutex
together with drm_sched_push_job(). See the kerneldoc for
drm_sched_push_job().
