Subject: [PATCH RFC v8 20/56] crypto:ccp: Define the SEV-SNP commands
Date: Mon, 20 Feb 2023 12:38:11 -0600 [thread overview]
Message-ID: <20230220183847.59159-21-michael.roth@amd.com> (raw)
In-Reply-To: <20230220183847.59159-1-michael.roth@amd.com>
From: Brijesh Singh <brijesh.singh@amd.com>
AMD introduced the next generation of SEV called SEV-SNP (Secure Nested
Paging). SEV-SNP builds upon existing SEV and SEV-ES functionality
while adding new hardware security protection.
Define the commands and structures used to communicate with the AMD-SP
when creating and managing the SEV-SNP guests. The SEV-SNP firmware spec
is available at developer.amd.com/sev.
