Bitland, the Chinese OEM that manufactured systems for Lenovo and other companies until being added to the US Entity List due to being accused of using Uyghur forced labor, is expected to see a WMI driver added to the Linux 7.1 kernel for better supporting Bitland laptops.

The Bitland MIFS WMI driver was developed via reverse engineering the Windows Management Instrumentation interface on the systems. This open-source driver for Bitland laptops allows setting the quiet/balanced/performance platform profiles, hardware sensor monitoring support exposed via HWMON interfaces, keyboard backlight controls, GPU mode selection, hotkey handling, and a fan boost mode for better cooling/thermals.

The HWMON integration provides thermal monitoring on the CPU, GPU, and system fan speeds.

Those with Bitland-manufactured laptops can learn more about this new driver via [1]this commit queued into the platform-drivers-x86 "for-next" Git branch ahead of the upcoming Linux 7.1 merge window.
