[PATCH] drm/msm/a3xx: remove TPL1 regs from snapshot

2019-06-24 Thread Rob Clark
From: Rob Clark These regs are write-only, and the hw throws a hissy-fit (ie. reboots) when we try to read them for GPU state snapshot, in response to a GPU hang. It is rather impolite when GPU recovery triggers an insta- reboot, so lets remove the TPL1 registers from the snapshot. Fixes: 7198e
