Thanks for clarification. So the measurement of the ACPI table from QEMU looks like below, right?

  Status = TpmMeasureAndLogData (
             1,
             EV_PLATFORM_CONFIG_FLAGS,     <-- event type
             EV_POSTCODE_INFO_ACPI_DATA,  <-- "ACPI DATA"
             ACPI_DATA_LEN,
             (VOID *)(UINTN)Table,
             TableSize
             );

Thanks
Min
