From cf48bddd31deefb9ab07de9a4d0150da6610198a Mon Sep 17 00:00:00 2001 From: Juha-Pekka Heikkila Date: Wed, 28 Feb 2024 16:02:25 +0200 Subject: [PATCH] drm/i915/display: Disable AuxCCS framebuffers if built for Xe MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit AuxCCS framebuffers don't work on Xe driver hence disable them from plane capabilities until they are fixed. FlatCCS framebuffers work and they are left enabled. CCS is left untouched for i915 driver.
