The Lenovo Gaming Series WMI Drivers were initially left out of the recent Linux v6.15 kernel merge window, but yesterday, the v5 patches were published for the series. The updated patches bring a few minor changes, such as improved code formatting and some basic improvements.

The Lenovo Gaming Series WMI Drivers have been working on enabling extra functionality for Lenovo gaming-oriented hardware under Linux. These drivers are particularly interesting with the Lenovo Legion Go S handheld having an official Steam OS option. The current version of the Lenovo Gaming Series WMI Drivers supports three WMI interfaces:
- “Gamezone”
- “Other Mode”
- “LENOVO_CAPABILITY_DATA_01”
These interfaces work together to provide getting and setting values, as well as input validation. The driver structure is designed to be extended by adding new interfaces in the future. According to developer Derek J. Clark:
“Adds support for the Lenovo “Gaming Series” of laptop hardware that use WMI interfaces that control various power settings. There are multiple WMI interfaces that work in concert to provide getting and setting values as well as validation of input. Currently only the “Gamezone”, “Other Mode”, and “LENOVO_CAPABILITY_DATA_01” interfaces are implemented, but I attempted to structure the driver so that adding the “Custom Mode”, “Lighting”, and other data block interfaces would be trivial in a later patches. This driver attempts to standardize the exposed sysfs by mirroring the asus-armoury driver currently under review. As such, a lot of inspiration has been drawn from that driver.”
The Lenovo Gaming Series WMI Drivers are still under development, but the recent updates bring us closer to seeing these drivers in action on Linux. With the work on these Lenovo gaming drivers appearing to settle down, hopefully they’ll be ready for upstreaming in time for the Linux v6.16 cycle this summer.
