A recently posted patch series for the MSI WMI platform driver is aiming this open-source driver to reach parity with MSI's official Windows application/driver for the MSI Claw gaming handheld systems.

The patches for the MSI WMI platform driver add support for managing fan cuves, ACPI Platform Profiles, TDP power controls, and battery limiting for all of the MSI Claw gaming handhelds under Linux. These features are what bring that MSI Linux driver to parity with what MSI Claw customers can utilize under Microsoft Windows.

The MSI driver patches by Antheas Kapenekakis introduce a quirk system, PL1/PL2 support via dfirmware attributes, and various other changes too as part of enabling these msi-wmi-platform driver features.

"This draft patch series brings into parity the msi-wmi-platform driver with the MSI Center M Windows application for the MSI Claw (all models). Unfortunately, MSI Center M and this interface do not have a discovery API, necessitating the introduction of a quirk system."

There still are some outstanding items that need to be addressed but for those with an MSI Claw handheld system running Linux, you can learn more via [1]this patch series .
