The x86 platform drivers co-maintainer Ilpo Järvinen sent out the pull request today of all the feature additions set for the in-development [1]Linux 6.15 kernel. As usual, most of the platform-drivers-x86 material is around improvements to benefit modern Intel Core and AMD Ryzen laptops.

First up with the new platform-driver-x86 material for Linux 6.15 is new hardware support tacked on to the Intel Power Management Controller (PMC) driver. The Intel PMC code with Linux 6.15 adds support for the new Arrow Lake H and Arrow Lake U SoCs as well as preparing for upcoming Intel Core Ultra Series 3 "Panther Lake" SoCs.

Also on the Intel side the Speed Select Technology (SST) driver has improved its multi-die handling.

For improving Samsung Galaxy Book laptop support on Linux, a new "samsung-galaxybook" driver is introduced. This open-source driver has been in the works for several months and allows for [2]Samsung Galaxy Books to enjoy working ACPI platform Profile, batter charge control, and other features .

The Alienware WMI driver meanwhile has seen a code refactoring and splitting off of its legacy driver code.

The Lenovo WMI driver meanwhile has added support for the microphone and audio mute LEDs so they are properly toggled when used under Linux.

While for ARM laptops rather than x86, this pull request also adds [3]the new Huawei Matebook E Go laptop EC driver . This new driver allows battery and charger monitoring, Fn lock controls, temperature sensors, tablet lid status, USB-C features, and more to work nicely under Linux with the Huawei Matebook E Go laptops.

More details on all of these x86 platform driver enhancements for the Linux 6.15 merge window via today's [4]pull request .
