c7dbc6c9ae5c3baa3be755a228a349374d043b5b is the first bad commit commit c7dbc6c9ae5c3baa3be755a228a349374d043b5b Author: Matt Roper <matthew.d.roper@intel.com> AuthorDate: Mon Jul 7 11:19:57 2014 -0700 Commit: Dave Airlie <airlied@redhat.com> CommitDate: Tue Jul 8 11:56:21 2014 +1000 drm: Remove command line guard for universal planes Universal planes are ready to leave 'experimental' state so drop the kernel command line parameter that we've been hiding them behind. Userspace clients that wish to receive universal planes will still need to opt-in by setting the appropriate capability bit, so this should have no impact on existing userspace.
