Subject: [PATCH Part2 v6 12/49] crypto: ccp: Add support to initialize the AMD-SP for SEV-SNP
Date: Mon, 20 Jun 2022 23:04:29 +0000 [thread overview]
Message-ID: <87a0481526e66ddd5f6192cbb43a50708aee2883.1655761627.git.ashish.kalra@amd.com> (raw)
In-Reply-To: <cover.1655761627.git.ashish.kalra@amd.com>
From: Brijesh Singh <brijesh.singh@amd.com>
Before SNP VMs can be launched, the platform must be appropriately
configured and initialized. Platform initialization is accomplished via
the SNP_INIT command. Make sure to do a WBINVD and issue DF_FLUSH command
to prepare for the first SNP guest launch after INIT.
