| H A D | intel_guc_reg.h | diff 6f67930af78f10ac7a1a9ba81ec606a9bd07749f Wed May 04 15:48:15 CDT 2022 Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> drm/i915/huc: Prepare for GSC-loaded HuC
HuC loading via GSC is performed via a PXP command sent through the mei
modules, so we need both MEI_GSC and MEI_PXP to be available. Given that
the GSC will do both the transfer and the authentication, the legacy HuC
loading paths can be safely skipped.
Also note that the GSC-loaded HuC survives GT reset.
v2: move the huc_is_authenticated() function to this patch.
