Enable HDCP for Xe by defining functions which take care of interaction of HDCP as a client with the GSC CS interface. Add intel_hdcp_gsc_message to Makefile and add corresponding changes to xe_hdcp_gsc.c to make it build. --v2 -add kfree at appropriate place [Daniele] -remove useless define [Daniele] -move host session logic to xe_gsc_submit.c [Daniele] -call xe_gsc_check_and_update_pending directly in an if condition [Daniele] -use xe_device instead of drm_i915_private [Daniele] --v3 -use xe prefix for newly exposed function [Daniele] -remove client specific defines from intel_gsc_mtl_header [Daniele] -add missing kfree() [Daniele] -have NULL check for hdcp_message in finish function [Daniele] -dont have too many variable declarations in the same line [Daniele] --v4 -don't point the hdcp_message structure in xe_device to anything until it properly gets initialized [Daniele] --v5 -Squash commits for buildability --v6 -Order includes alphabetically [Lucas] Signed-off-by: Suraj Kandpal <suraj.kandpal@intel.com> Reviewed-by: Arun R Murthy <arun.r.murthy@intel.com> Signed-off-by: Mika Kahola <mika.kahola@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240306024247.1857881-6-suraj.kandpal@intel.com
