142 -------------------
145 data contains a flag byte and a 28 byte controller firmware version string.
156 --------------------
158 Fan speed sensors can be accessed by selecting subfeature ``0x00``. The output data contains
159 up to four 16-bit fan speed readings in big-endian format. Most machines do not support all

177 Reverse-Engineering the MSI WMI Platform interface
183 The underlying embedded controller interface is used by the ``msi-ec`` driver, and it seems
