Subject: [PATCH v10 29/50] KVM: SEV: Add KVM_SEV_SNP_LAUNCH_FINISH command
Date: Mon, 16 Oct 2023 08:27:58 -0500 [thread overview]
Message-ID: <20231016132819.1002933-30-michael.roth@amd.com> (raw)
In-Reply-To: <20231016132819.1002933-1-michael.roth@amd.com>
From: Brijesh Singh <brijesh.singh@amd.com>
The KVM_SEV_SNP_LAUNCH_FINISH finalize the cryptographic digest and stores
it as the measurement of the guest at launch.
While finalizing the launch flow, it also issues the LAUNCH_UPDATE command
to encrypt the VMSA pages.
If its an SNP guest, then VMSA was added in the RMP entry as
a guest owned page and also removed from the kernel direct map
so flush it later after it is transitioned back to hypervisor
state and restored in the direct map.

+21. KVM_SNP_LAUNCH_FINISH
+-------------------------
+
+After completion of the SNP guest launch flow, the KVM_SNP_LAUNCH_FINISH command can be
+issued to make the guest ready for the execution.
+
+Parameters (in): struct kvm_sev_snp_launch_finish
+
+Returns: 0 on success, -negative on error
+
+::
+
+ struct kvm_sev_snp_launch_finish {
+ __u64 id_block_uaddr;

+ __u8 auth_key_en;
+ __u8 host_data[32];
+ __u8 pad[6];
+ };
+
+
+See SEV-SNP specification for further details on launch finish input parameters.
