From 6a418fcd84d655e97333627c4247a318e99b0ecf Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Tue, 10 Feb 2015 17:16:14 +0000 Subject: [PATCH] drm/i915: Use fb modifiers in intel_check_cursor_plane Also drop the mutex since with universal planes there is always a proper framebuffer around which wraps the underlying bo. Which means tiling is locked down. This was different in the old code which directly took gem handles. The looking though was always cargo-cult since races where not prevented in any way. v2: Unconditionally enforce untiled, because cursors are always untiled. The check for physical or gtt cursor is irrelevant.
