SPDX-License-Identifier: GPL-2.0-only + +============================== +WMI embedded Binary MOF driver +============================== + +Introduction +============ + +Many machines embed WMI Binary MOF (Managed Object Format) metadata used to +describe the details of their ACPI WMI interfaces. The data can be decoded +with tools like `bmfdec <https://github.com/pali/bmfdec>`_ to obtain a +human readable WMI interface description, which is useful for developing +new WMI drivers. + +The Binary MOF data can be retrieved from the ``bmof`` sysfs attribute of the +associated WMI device. Please note that multiple WMI devices containing Binary +MOF data can exist on a given system. + +WMI interface +============= + +The Binary MOF WMI device is identified by the WMI GUID ``05901221-D566-11D1-B2F0-00A0C9062910``. +The Binary MOF can be obtained by doing a WMI data block query. The result is +then returned as an ACPI buffer with a variable size. |
