Subject: [PATCH v4 06/13] x86/keylocker: Define Key Locker CPUID leaf
Date: Mon, 13 Dec 2021 16:52:05 -0800 [thread overview]
Message-ID: <20211214005212.20588-7-chang.seok.bae@intel.com> (raw)
In-Reply-To: <20211214005212.20588-1-chang.seok.bae@intel.com>
Define the feature-specific CPUID leaf and bits. Both Key Locker enabling
code in the x86 core and AES Key Locker code in the crypto library will
reference them.
