Define intel_hdcp_gsc_check_status in Xe to account for changes in i915 and Xe. intel_hdcp_check_status always returns false as gsc cs interface is not yet ported. intel_hdcp_gsc_cs_required always returns true as going forward gsc cs will always be required by upcoming platforms --v5 -Define intel_hdcp_gsc_cs_required() --v6 -Explain reasons for the return values [Chaitanya] Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2023-12-21drm/xe/display: Create a dummy version for vga decodeUma Shankar
This introduces an exclusive version of vga decode for xe. Rest of the display changes will be re-used from i915. Currently it adds just a dummy implementation. VGA decode needs to be handled correctly in i915, proper implementation will be adopted once the i915 changes are finalized and merged in upstream. v2: Addressed Arun's review comments Signed-off-by: Uma Shankar <uma.shankar@intel.com> Reviewed-by: Arun R Murthy <arun.r.mruthy@intel.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2023-12-21drm/xe/display: ensure clear-color surfaces are cpu mappableMatthew Auld
The KMD needs to access the clear-color value stored in the buffer via the CPU. On small-bar systems reject any buffers that are potentially not CPU accessible.

2023-12-21drm/xe/display: Implement display supportMaarten 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>
