Subject: [Intel-xe] [PATCH 0/2] HuC authentication via GSC
Date: Tue, 28 Nov 2023 17:17:17 -0800	[thread overview]
Message-ID: <20231129011721.2793482-1-daniele.ceraolospurio@intel.com> (raw)

Starting on MTL, in addition to the authentication via GuC, we need to
perform a second HuC authentication via GSC. This second authentication
is required to allow the HuC to process protected content and is
performed by sending a dedicated PXP command to the GSC firmware.
