Description

The dmi_hpe_mhs_riser_t structure holds the decoded HP/HPE extension board inventory record of a PCIe riser of an MHS platform. It is returned by dmi_entity_info for the structures of board type DMI_HPE_BOARD_TYPE_MHS_RISER.

The structures are decoded by dmi_hpe_riser_spec and dmi_hpe_mhs_riser_spec, of type DMI_TYPE(hpe_mhs_riser), declared in <opendmi/module/hpe.h>, once the HPE extension module (dmi_hpe_module) is enabled, which it is for HP and HPE servers. The board type at offset 0x04 selects the specification, and the structures of other board types are not decoded. The structure lives as long as the context it has been decoded in.

Fields

board_type

Type of the board, DMI_HPE_BOARD_TYPE_MHS_RISER, see dmi_hpe_board_type.

riser_id

ID of the riser.

firmware_major

Major version of the firmware of the riser, zero if the riser has no firmware.

firmware_minor

Minor version of the firmware of the riser.

is_downgradable

Whether the firmware of the riser may be downgraded.

name

Name of the riser.

slot_total

Number of the slots the structure declares.

slot_count

Number of elements of slot_ids, which is smaller than slot_total when the data ends before the last slot.

slot_ids

IDs of the slots of the riser. May be nullptr when slot_count is 0.

Standards

Not part of the SMBIOS specification. Defined by HP and HPE for their servers; the layout is the one dmidecode documents.
