Subject: [PATCH Part2 RFC v4 11/40] crypto:ccp: Define the SEV-SNP commands
Date: Wed, 7 Jul 2021 13:35:47 -0500 [thread overview]
Message-ID: <20210707183616.5620-12-brijesh.singh@amd.com> (raw)
In-Reply-To: <20210707183616.5620-1-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.
