dmi_intel_asf

Synopsis

#include <opendmi/entity/intel/asf.h>

typedef struct dmi_intel_asf {
    uint8_t version;
    const char *name;
    const char *identifier;
    uint8_t parameter;
    uint8_t extra[8];
    bool has_extra;
} dmi_intel_asf_t;

Description

The dmi_intel_asf_t structure holds the decoded Intel ASF information, which names the Alert Standard Format (ASF) support of the platform. The meaning of the fields other than the strings is not established.

The structure is returned by dmi_entity_info for the structures decoded by dmi_intel_asf_spec, of type DMI_TYPE(intel_asf), declared in <opendmi/module/intel.h>, once the Intel extension module (dmi_intel_module) is enabled, which is done for any platform with Intel processors when the context has DMI_CONTEXT_FLAG_AUTO_MODULES. It lives as long as the context it has been decoded in.

The structures are told by the version, 1, and by the number of the first string, 1, at offset 0x04, since other vendors give type 129 to structures of their own, e.g. Gigabyte. The strings are the ones of the Intel reference code, e.g. Intel_ASF and Intel_ASF_001, or of the vendor of the firmware, e.g. Dell_ASF_001 or Insyde_ASF_001.

Fields

version

Version of the structure, presumably, 1 in all known data.

name

Name of the ASF support, e.g. Intel_ASF or Insyde_ASF_001.

identifier

Identifier of the ASF support, e.g. Intel_ASF_001 or Dell_ASF_002.

parameter

Value whose meaning is not established, 1 in most known data and 0 on ThinkPad T61p.

extra

Bytes which follow in the structures of 16 bytes, whose meaning is not established, e.g. on Acer Aspire 3680. Not shown when has_extra is not set.

has_extra

Whether the structure holds extra, which the structures of 8 bytes leave out.
