From 7ea0e9f27790a9890e97b3068a681f958197c0e5 Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Fri, 4 Dec 2020 17:07:56 +0100 Subject: backend/drm: force LINEAR for cursor plane formats If the kernel driver doesn't support modifiers, it still expects cursor FBs to have a LINEAR layout. See [1] for expectations for framebuffers attached to the cursor plane.
