From: Alvin Lee Date: Wed, 12 Apr 2023 21:06:46 +0000 (-0400) Subject: drm/amd/display: Query GECC enable for SubVP disable X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1938bcdc4b530d6413e03f238c2df56f99f17220;p=linux.git drm/amd/display: Query GECC enable for SubVP disable - We want to disable SubVP if Graphics Error Correction/Correcting Code (GECC) is enabled. - After reading feature caps from DMCUB during init, use the GECC enable/disable info to determine if SubVP can be enabled or not.
