dmi_dell_device_names

Synopsis

#include <opendmi/entity/dell/device-names.h>

typedef struct dmi_dell_device_names {
    uint8_t unknown;
    size_t device_count;
    dmi_dell_device_name_entry_t *devices;
} dmi_dell_device_names_t;

Description

The dmi_dell_device_names_t structure holds the decoded Dell device names (type 225), which give the devices of a kind, e.g. the processors or the memory devices, the names the management controller (iDRAC) of a PowerEdge server knows them by, its fully qualified device descriptors (FQDD). The structures are found on PowerEdge servers of the 13th and 14th generations, e.g. PowerEdge R630 and R740xd, one for the processors and one for the memory devices.

The structure is returned by dmi_entity_info for the structures decoded by dmi_dell_device_names_spec, of type DMI_TYPE(dell_device_names), declared in <opendmi/module/dell.h>, once the Dell extension module (dmi_dell_module) is enabled. It lives as long as the context it has been decoded in.

The layout is reverse engineered from the dumps of the data corpus, since no public source describes the structure, and the members whose meaning is not established are named after their position.

Fields

unknown

Value whose meaning is not established, 1 in all known data.

device_count

Number of elements of devices.

devices

Names of the devices, see dmi_dell_device_name_entry. May be nullptr when device_count is 0.
