Subject: [Intel-gfx] [PATCH 0/3] Support bigger GuC RSA keys
Date: Wed, 8 Dec 2021 16:56:07 -0800 [thread overview]
Message-ID: <20211209005610.1499729-1-daniele.ceraolospurio@intel.com> (raw)
Some of the newer platforms use a bigger RSA key to authenticate the GuC,
which is provided to the HW via a ggtt-pinned object instead of mmio.
While doing the changes for this I've also spotted an inconsistency in
the error status of the fw on init failure, so I've added a path to fix
that as well.
