dmi_intel_rsd_tpm
Synopsis
#include <opendmi/entity/intel-rsd/tpm.h>
#include <opendmi/module/intel-rsd.h>
typedef struct dmi_intel_rsd_tpm {
uint8_t config_index;
const char *version;
dmi_intel_rsd_tpm_status_t status;
} dmi_intel_rsd_tpm_t;Description
The dmi_intel_rsd_tpm_t structure holds the decoded Trusted Platform Module
(TPM) information structure (type 195) of Intel Rack Scale Design (RSD)
firmware: one TPM configuration of the platform, with the version of the TPM
and whether it is enabled. The pod manager selects the configuration to use
by its index.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(intel_rsd_tpm), once the Intel RSD extension module
(dmi_intel_rsd_module, declared in <opendmi/module/intel-rsd.h>) has been
enabled in the context with dmi_add_extension(). It lives as long as the
context it has been decoded in.
Fields
config_index-
One-based index of the configuration, the one the pod manager (PSME) passes to the IPMI Set TPM Configuration command to select it. The
value.rangelint rule reports a structure which holds 0. version-
Version of the TPM,
nullptrif the structure does not carry it. status-
Whether the TPM is enabled (see
dmi_intel_rsd_tpm_status).
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_entity_t *entity = dmi_registry_lookup_first(registry,
DMI_TYPE(intel_rsd_tpm), true);
dmi_intel_rsd_tpm_t *tpm = dmi_entity_info(entity,
DMI_TYPE(intel_rsd_tpm));
if (tpm != nullptr) {
const char *status = dmi_intel_rsd_tpm_status_name(tpm->status);
printf("TPM %s: %s\n",
(tpm->version != nullptr) ? tpm->version : "unknown version",
(status != nullptr) ? status : "unknown status");
