From 98ad74c6a92e195f8c9577a5b2e4a4057ce5d5a4 Mon Sep 17 00:00:00 2001 From: Ilya Bakoulin Date: Thu, 15 Apr 2021 16:02:25 -0400 Subject: [PATCH] drm/amd/display: Handle pixel format test request [Why] Some DSC tests fail because stream pixel encoding does not change its value according to the type requested in the DPCD test params. [How] Set stream pixel encoding before updating DSC config and configuring the test pattern.
