From 953c2901c860da16963b48db8344bf0fd5b03040 Mon Sep 17 00:00:00 2001 From: Anthony Koo Date: Fri, 6 Apr 2018 13:55:39 -0400 Subject: [PATCH] drm/amd/display: refactor vupdate interrupt registration We only need to register once OS calls the interrupt control. Also, if we are entering static screen mode, disable after ramping is done. Disable shall be done via timer of 2 seconds regardless of ramping complete or not, just to simplify. Also, ramp to mid instead of min, due to better flicker performance...
