From 73076790e25717b7d452c2eab0bfb118826e5b61 Mon Sep 17 00:00:00 2001 From: Sung Lee Date: Thu, 4 Feb 2021 08:21:15 -0500 Subject: drm/amd/display: Copy over soc values before bounding box creation [Why] With certain fclock overclocks, state 1 may be chosen as the closest clock level. This may result in this state being empty if not populated beforehand, resulting in black screens and screen corruption. [How] Copy over all soc states to clock_limits before bounding box creation to avoid any cases with empty states.
