dmi_sun_processor_ex
Synopsis
#include <opendmi/entity/sun/processor-ex.h>
typedef struct dmi_sun_processor_ex {
dmi_handle_t processor_handle;
uint8_t fru;
uint8_t apic_id_total;
size_t apic_id_count;
uint16_t *apic_ids;
} dmi_sun_processor_ex_t;Description
The dmi_sun_processor_ex_t structure holds the decoded Sun processor extended
information structure (type 132), which adds the initial APIC IDs of the
strands (hardware threads) of a processor to its processor information
structure (type 4). It is not part of SMBIOS: Sun firmware provides it, and the
library decodes it only when the Sun extension module (dmi_sun_module,
declared in <opendmi/module/sun.h>) is enabled in the context with
dmi_add_extension.
The structure is returned by dmi_entity_info for the structures of type
DMI_TYPE(sun_processor_ex), and lives as long as the context it has been
decoded in.
Fields
processor_handle-
Handle of the processor information structure (type 4) this structure extends. The library does not resolve it into an entity.
fru-
Field-replaceable unit (FRU) indicator of the processor, as stored.
apic_id_total-
Number of initial APIC IDs the structure declares.
apic_id_count-
Number of elements of
apic_ids: the IDs the structure holds in full, which may be fewer thanapic_id_totalwhen the structure is truncated. apic_ids-
Initial APIC IDs of the strands of the processor;
nullptrifapic_id_totalis 0.
Examples
dmi_registry_t *registry = dmi_get_registry(context);
dmi_entity_t *entity = dmi_registry_lookup_first(registry,
DMI_TYPE(sun_processor_ex), true);
dmi_sun_processor_ex_t *info =
dmi_entity_info(entity, DMI_TYPE(sun_processor_ex));
for (size_t i = 0; (info != nullptr) && (i < info->apic_id_count); i++)
printf("strand %zu: APIC ID 0x%04X\n", i, (unsigned)info->apic_ids[i]);
