Description

The dmi_hpe_dimm_config_t structure holds the decoded HP/HPE DIMM current configuration record, which describes a memory region configured on a module of a memory device (type 17), e.g. of a persistent memory one, and the interleave set it belongs to. There is a record for each region.

The structure is returned by dmi_entity_info for the structures decoded by dmi_hpe_dimm_config_spec, of type DMI_TYPE(hpe_dimm_config), declared in <opendmi/module/hpe.h>, once the HPE extension module (dmi_hpe_module) is enabled, which it is for HP and HPE servers. It lives as long as the context it has been decoded in.

Fields

device_handle

Handle of the memory device structure (type 17).

region_id

ID of the region, unique on the module.

is_volatile

Whether the region is volatile, its data lost on a power cycle.

is_byte_accessible

Whether the region is byte accessible persistent memory, its data kept through a reset.

is_block_io

Whether the region is block I/O persistent memory.

raw_size

Size of the region in mebibytes, as the structure holds it.

size

Size of the region in bytes.

passphrase_state

State of the passphrase, as the structure holds it.

is_passphrase_enabled

Whether a passphrase is required, byte accessible persistent regions only: any state other than zero.

interleave_set

1-based index of the interleave set of the region, unique per set. Regions of the same index are interleaved.

interleave_dimm_count

Number of the DIMMs of the interleave set.

interleave_health

Health of the interleave set, see dmi_hpe_interleave_health, or DMI_HPE_INTERLEAVE_HEALTH_ABSENT if the structure is too short to hold it.
