Subject: [PATCH v2 0/4] fixes for Adreno A5Xx preemption
Date: Sun, 1 Sep 2024 13:53:59 +0000 [thread overview]
Message-ID: <20240901135419.1075412-1-vladimir.lypak@gmail.com> (raw)
There are several issues with preemption on Adreno A5XX GPUs which
render system unusable if more than one priority level is used. Those
issues include persistent GPU faults and hangs, full UI lockups with
idling GPU.
---
Changes in v2:
- Use spinlock to serialize preemption initiation in patch 3
- Added Reviewed-by on patch 2

Vladimir Lypak (4):
drm/msm/a5xx: disable preemption in submits by default
drm/msm/a5xx: properly clear preemption records on resume
drm/msm/a5xx: fix races in preemption evaluation stage
drm/msm/a5xx: workaround early ring-buffer emptiness check
