x86 OEM laptop and platform firmware drivers (ACPI/WMI vendor extensions)

A large collection of small drivers handling vendor-specific extras on x86 laptops from ASUS, Dell, HP, Lenovo, Acer, MSI, Samsung, Toshiba and others: hotkeys, function-key LEDs, fan profiles, battery charge thresholds, camera-privacy switches, rfkill toggles and similar ACPI/WMI firmware features that aren't covered by generic standards.

recommendation

It should stay because this is one of the most actively maintained corners of the kernel and directly supports laptops being sold new in 2025 and 2026. Recent traffic on the platform-driver-x86 mailing list shows fixes and quirks still landing for current ASUS Zenbook and Vivobook models, and major OEMs continue to ship new hardware that depends on these drivers for basic usability features like hotkeys and LEDs.

codex reasoning notes (technical)

Keep: this is an active umbrella driver directory for current OEM x86 laptops and platform firmware features, not a stranded legacy driver. Evidence came from local shell reads of drivers/platform/x86/Kconfig and Makefile, mapped to the canonical kernel.org tree URL; lore_activity on drivers/platform/x86/asus-wmi.c yielded the two lore URLs showing March-April 2026 fixes/quirks for current ASUS machines; web search returned the two ASUS URLs showing those laptop lines are still marketed. I attempted removal-signal searches with lore_regex and lore_substr_subject for remove/deprecate/obsolete on platform-driver-x86, but they timed out rather than producing evidence of an active removal effort.
