AMD Sensor Fusion Hub 1.1 (MP2) for Ryzen laptops
An on-SoC microcontroller built into AMD Ryzen mobile platforms that aggregates readings from a laptop's built-in sensors, such as accelerometer, gyroscope, magnetometer and ambient light sensor, and reports them to the OS. The 1.1 (MP2) generation covers Ryzen 6000-era and newer laptops from vendors like Lenovo and HP, still sold new in 2025.
recommendation
It should stay because the hardware ships in current AMD Ryzen laptops (Ryzen 6000 and later), the driver is still receiving real bug fixes upstream as recently as October 2025, and there is no sign of a planned removal. Without it, built-in sensors like the accelerometer and ambient light sensor on a large swath of modern AMD-powered convertibles and ultrabooks would not work.

The sfh1_1 code was still receiving functional fixes in late 2025 ('HID: amd_sfh: Stop sensor before starting', committed 2025-10-30), which argues against deprecation.

SFH1.1 support was added as dedicated functionality in 2022, confirming this directory is the active implementation for that hardware generation rather than dead compatibility glue.

codex reasoning notes (technical)
Shell `git log` on the local kernel snapshot produced the 2025 fix commit and the 2022 SFH1.1 introduction commit; I converted those hashes into canonical git.kernel.org commit URLs. A shell grep over amd-sfh-hid history found no deprecation/removal-oriented series for this driver family, only normal cleanup and feature work. `web.search_query` found the LKDDb page for kernel support scope, Lenovo's AMD Ryzen 6000 laptop page for new-hardware sales evidence, and a linux-hardware probe page for present-day deployment evidence. Net: active upstream maintenance plus still-sold Ryzen laptop platforms means keep, not deprecate.
