From 610f56371ad2bb70059419949d3b1484ca74a7dd Mon Sep 17 00:00:00 2001 From: Josip Pavic Date: Fri, 23 Aug 2019 20:54:12 -0400 Subject: [PATCH] drm/amd/display: define parameters for abm 2.3 [Why] Current configuration 0 is just a placeholder, and final parameters needed. Also, configuration 1 is expected to emulate ABM 2.1 but is too aggressive. [How] Redefine configuration 0 with the finalized parameters, and increase the contrast gain of configuration 1 so that it properly emulates ABM 2.1.
