From 0753e56e9a01fc5350a703dcae55c14efdfb3e49 Mon Sep 17 00:00:00 2001 From: Evan Quan Date: Mon, 23 Dec 2019 16:13:48 +0800 Subject: [PATCH] drm/amdgpu: correct RLC firmwares loading sequence Per confirmation with RLC firmware team, the RLC should be unhalted after all RLC related firmwares uploaded. However, in fact the RLC is unhalted immediately after RLCG firmware uploaded. And that may causes unexpected PSP hang on loading the succeeding RLC save restore list related firmwares. So, we correct the firmware loading sequence to load RLC save restore list related firmwares before RLCG ucode. That will help to get around this issue.
