Open-source developer Armin Wolf has been working most recently on marshalling support for the Windows Management Instrumentation (WMI) platform code within the Linux kernel. This WMI marshalling support is to better match the behavior of Microsoft Windows’ WMI ACPI driver and ultimately to allow for better compatibility with some ACPI firmware and enhancing some WMI drivers.

The WMI marshalling support is up to its second post-RFC revision for this effort to better match the handling of Windows’ WMI ACPI driver.
