dmi_processor_voltage_data

Synopsis

#include <opendmi/entity/processor.h>

typedef union dmi_processor_voltage_data {
    dmi_byte_t __value;
    struct {
        dmi_byte_t value      : 7;
        dmi_byte_t is_current : 1;
    };
} dmi_processor_voltage_data_t;

Description

The dmi_processor_voltage_data_t union describes the voltage field of the processor information structure (type 4) of SMBIOS as it is stored: one byte holding either the current voltage of the processor or the voltages its socket accepts.

The decoder splits the field into the voltage and supported_voltages fields of dmi_processor_t, so the union is only needed to read or build the stored byte. The specification deprecates the field since SMBIOS 3.8.

Fields

__value

Stored byte.

value

Current voltage, in tenths of volt, if is_current is set, and the set of the supported voltages in the layout of dmi_processor_voltages otherwise.

is_current

Set if value holds the current voltage, clear in the legacy mode, where it holds the supported voltages.
