From 397a9bc588797907fda9879c2f8cfda1a436e8ce Mon Sep 17 00:00:00 2001 From: Roman Li Date: Tue, 1 Oct 2019 09:45:38 -0400 Subject: drm/amdgpu/display: add dc feature mask for psr enablement [Why] Adding psr mask to dc features allows selectively disable/enable psr. Current psr implementation may not work with non-pageflipping application. Until resolved it should be disabled by default. [How] Add dcfeaturemask for psr enablement. Disable by default. To enable set amdgpu.dcfeaturemask=0x8 in grub kernel command line.
