Subject: [PATCH RFC v8 45/56] KVM: SVM: Provide support for SNP_GUEST_REQUEST NAE event
Date: Mon, 20 Feb 2023 12:38:36 -0600 [thread overview]
Message-ID: <20230220183847.59159-46-michael.roth@amd.com> (raw)
In-Reply-To: <20230220183847.59159-1-michael.roth@amd.com>
From: Brijesh Singh <brijesh.singh@amd.com>
Version 2 of GHCB specification added the support for two SNP Guest
Request Message NAE events. The events allows for an SEV-SNP guest to
make request to the SEV-SNP firmware through hypervisor using the
SNP_GUEST_REQUEST API define in the SEV-SNP firmware specification.
The SNP_EXT_GUEST_REQUEST is similar to SNP_GUEST_REQUEST with the
difference of an additional certificate blob that can be passed through
the SNP_SET_CONFIG ioctl defined in the CCP driver. The CCP driver
provides snp_guest_ext_guest_request() that is used by the KVM to get
both the report and certificate data at once.
