From be6dd3c8e884f7b1a9f76c3ad1efd068b981f7d5 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Fri, 11 Aug 2023 09:06:10 -0700 Subject: [PATCH] drm/xe/xe2: AuxCCS is no longer used Starting with Xe2, all platforms (including igpu platforms) use FlatCCS compression rather than AuxCCS. Similar to PVC, any future platforms that don't support FlatCCS should not attempt to fall back to AuxCCS programming.
