Description

The dmi_intel_platform_t structure holds the decoded Intel platform information, which gives the versions of the firmware components and some settings of an Intel Bay Trail platform, all of them as strings, as the firmware writes them: the numbers in hexadecimal, and the settings as their values, e.g. 0 or 1.

The structure is returned by dmi_entity_info for the structures decoded by dmi_intel_platform_spec, of type DMI_TYPE(intel_platform), 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 their length of 26 bytes, since Intel server boards give type 148 to structures of other layouts.
