From 87ac8fb08bc7c69a39842c73f3a9d06eb73f02cc Mon Sep 17 00:00:00 2001 From: Shirish S Date: Wed, 25 Apr 2018 14:42:28 +0530 Subject: [PATCH] drm/amd/display: disable FBC on underlay pipe FBC is not applicable for the underlay pipe, hence disallow enabling and disabling of the same. This also fixes the BUG hit of calling sleep in atomic context.
