From 50f8d21863b9b774b198e631d2b14878f6a54b5b Mon Sep 17 00:00:00 2001 From: Jordan Crouse Date: Tue, 24 Jul 2018 10:33:30 -0600 Subject: drm/msm/adreno: Add a5xx specific registers for the GPU state HLSQ, SP and TP registers are only accessible from a special aperture and to make matters worse the aperture is blocked from the CPU on targets that can support secure rendering. Luckily the GPU hardware has its own purpose built register dumper that can access the registers from the aperture. Add a5xx specific code to program the crashdumper and retrieve the wayward registers and dump them for the crash state. Also, remove a block of registers the regular CPU accessible list that aren't useful for debug which helps reduce the size of the crash state file by a goodly amount.
