	There's only one instance of the pcode per tile, and for GT-related accesses both the primary and media GT share the same register interface. Since Xe was using per-GT locking, the pcode mutex wasn't actually protecting everything that it should since concurrent accesses related to a tile's primary GT and media GT were possible.

2023-12-21	drm/xe/display: Implement display support	Maarten Lankhorst
	As for display, the intent is to share the display code with the i915 driver so that there is maximum reuse there. We do this by recompiling i915/display code twice. Now that i915 has been adapted to support the Xe build, we can add the xe/display support. This initial work is a collaboration of many people and unfortunately this squashed patch won't fully honor the proper credits. But let's try to add a few from the squashed patches: Co-developed-by: Matthew Brost <matthew.brost@intel.com> Co-developed-by: Jani Nikula <jani.nikula@intel.com> Co-developed-by: Lucas De Marchi <lucas.demarchi@intel.com> Co-developed-by: Matt Roper <matthew.d.roper@intel.com> Co-developed-by: Mauro Carvalho Chehab <mchehab@kernel.org> Co-developed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Co-developed-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
