From f50423436105e136e2409b500719334188a77aa6 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 20 Oct 2021 22:51:36 +0300 Subject: [PATCH] drm/i915: Add a platform independent way to check for CCS AUX planes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Future platforms change the location of CCS AUX planes in CCS framebuffers, so add intel_fb_is_ccs_aux_plane() to query for these planes independently of the platform. This function can be used everywhere instead of is_ccs_plane() (or is_ccs_plane() && !cc_plane()), since all the callers are only interested in CCS AUX planes (and not CCS color-clear planes). Add the corresponding intel_fb_is_gen12_ccs_aux_plane(), which can be used everywhere instead of is_gen12_ccs_plane(), based on the above explanation. This change also unexports the is_gen12_ccs_modifier(), is_gen12_ccs_plane(), is_gen12_ccs_cc_plane() functions as they are only used in intel_fb.c v1-v2: Unchanged v3: (Ville) - Use ccs_aux instead of the ccs_ctrl term everywhere. - Use color_plane instead of plane term for FB plane indicies. v4: Fix version range check.
