Laptop Improvements With Linux 5.14 Benefit Lenovo, Dell, Microsoft Surface Devices
This cycle there are some exciting additions to the Lenovo ThinkPad and Dell device support as well as continuing to improve the open-source (community-driven) Microsoft Surface support:
- The Think-LMI driver has been queued for changing BIOS settings from within Linux using the firmware-attributes sysfs area on newer Lenovo systems including ThinkPad laptops. This is a fun addition and the sysfs firmware-attributes support and initial driver for controlling BIOS settings from within Linux having been spearheaded recently by Dell.
- Dell Hardware Privacy support was merged for dealing with hardware-based kill switches on new Dell laptops for the microphone and web camera shutter assembly. They are hardware-based kill switches with the new Linux support being for exposing the state to user-space for informational purposes.
- The intel_skl_int3472 driver has been merged for handling of camera sensors on Intel devices with IPU3-attached MIPI cameras.
- Continued work improving the Microsoft Surface hardware support on Linux.
- A fix in the ISST SpeedSelect driver where its overhead was hurting some HPC benchmarks.
- Supporting controlling the second fan on the Lenovo X1 Carbon Gen9 laptop.
- The ASUS-NB-WMI driver support for the newer ASUS ROG Zephyrus G14 and G15 laptops that was previously added have been removed. The quirks were determined to be wrong.
