From 1dd50e634cb46880f3364ce629b09a37a5b3f888 Mon Sep 17 00:00:00 2001 From: Alvin Lee Date: Mon, 29 Apr 2024 17:39:35 -0400 Subject: [PATCH] drm/amd/display: Don't offload flip if not only address update [WHAT & HOW] Fast updates can consist of some stream updates as well (i.e., out_csc). In these cases we should not offload the flip to FW as we can only offload address only updates to FW.
