177 Reverse-Engineering the MSI WMI Platform interface
180 .. warning:: Randomly poking the embedded controller interface can potentially cause damage
183 The underlying embedded controller interface is used by the ``msi-ec`` driver, and it seems
184 that many methods just copy a part of the embedded controller memory into the output buffer.
186 This means that the remaining WMI methods can be reverse-engineered by looking which part of
187 the embedded controller memory is accessed by the ACPI AML code. The driver also supports a
