SnpDerivedKeyReq

Request structure for the SNP_GET_DERIVED_KEY request. See MSG_KEY_REQ in Table 18, “SEV Secure Nested Paging Firmware ABI specification”, Revision 1.55.

SnpDerivedKeyResp

Response structure for the SNP_GET_DERIVED_KEY request. See MSG_KEY_RSP in Table 20, “SEV Secure Nested Paging Firmware ABI specification”, Revision 1.55.

SnpPageInfo

Structure describing the pages being read during SNP ID block measurement. Each structure is hashed with the previous structures digest to create a final measurement

SnpPageType

The type of page described by SnpPageInfo

SnpPspIdBlock

Structure containing the completed SNP measurement of the IGVM file. The signature of the hash of this struct is the id_key_signature for igvm_defs::IGVM_VHS_SNP_ID_BLOCK.

SnpReport

Report structure. See ATTESTATION_REPORT in Table 22, “SEV Secure Nested Paging Firmware ABI specification”, Revision 1.55.

SnpReportReq

Request structure for the SNP_GET_REPORT request. See MSG_REPORT_REQ in Table 21, “SEV Secure Nested Paging Firmware ABI specification”, Revision 1.55.

SnpReportResp

Response structure for the SNP_GET_REPORT request. See MSG_REPORT_RSP in Table 24, “SEV Secure Nested Paging Firmware ABI specification”, Revision 1.55.
