The x86 platform driver updates have been merged for the ongoing [1]Linux 6.14 merge window. As usual the x86 platform driver updates are predominantly to benefit the many different Intel/AMD laptops out there with various OEM vendor features/functionality. Plus within the platform-drivers-x86 space is a growing number of AMD SoC drivers for not only laptops but also desktops/servers.

Among the x86 platform driver highlights for Linux 6.14 are:

- The Acer WMI driver now supports the PH14-51, PH16-72, and Nitro AN515-58 laptops. The Acer WMI driver now also has proper hardware monitoring (HWMON) support.

- The ACPI Platform Profile code can now register multiple platform profile handlers concurrently, support reporting "custom" profile for configurations outside the pre-defined profile, and more.

- The AMD Host System Management Port (HSMP) driver adds support for the HSMP v7 protocol.

- The AMD PMC driver now supports Family 1Ah Model 70h Zen 5 processors. The AMD PMC driver also adds STB support with Ryzen desktop processors.

- The AMD Platform Management Framework (PMF) driver now supports [2]custom BIOS inputs using the PMF-TA trusted application code. There is also support for passing sensor data from the AMD Sensor Fusion Hub (SFH) to the PMF-TA.

- Accelerometer support for the Dell Latitude E6330 and E6430 systems along with the Dell XPS 9550 laptop.

- The HP WMI driver adds fan and thermal support for the HP Victus 16-s1000 gaming laptop.

- The Lenovo ThinkPad ACPI driver adds support for the Phone Link key.
