TDINFO_STRUCT is defined as the TDX-specific TEE_INFO part of TDG.MR.REPORT. It contains the measurements and initial configuration of the TD that was locked at initialization and a set of measurement registers that are run-time extendable. These values are copied from the TDCS by the TDG.MR.REPORT function. Refer to the [TDX Module Base Spec] for additional details.

Fields

attributes: u64

TD’s ATTRIBUTES.

xfam: u64

TD’s XFAM.

mrtd: [u8; 48]

Measurement of the initial contents of the TD.

mr_config_id: [u8; 48]

Software-defined ID for non-owner-defined configuration of the guest TD – e.g., run-time or OS configuration.

mr_owner: [u8; 48]

Software-defined ID for the guest TD’s owner.

mr_owner_config: [u8; 48]

Software-defined ID for owner-defined configuration of the guest TD – e.g., specific to the workload rather than the run-time or OS.

rtmr0: [u8; 48]

Array of NUM_RTMRS (4) run-time extendable measurement registers.

rtmr1: [u8; 48]

rtmr2: [u8; 48]

rtmr3: [u8; 48]

servtd_hash: [u8; 48]

If is one or more bound or pre-bound service TDs, SERVTD_HASH is the SHA384 hash of the TDINFO_STRUCTs of those service TDs bound. Else, SERVTD_HASH is 0.

reserved: [u8; 64]
