The Acer Predator Helios 500's keyboard has four zones of RGB LEDs. This driver allows them to be controlled from Linux.
have you checked whether these LEDs are behind a GPIO controller (possibly in the SoC itself), that's potentially used for other things,
too ? If that's the case, we might run into trouble when one's implementing an gpio driver and using it with generic drivers (eg. buttons). I've haven't got a data sheet for the i9-11900 yet, but I'm quite sure it does have gpios and suspect they're used for those things, as well as extra keys, etc. This is a usual approach for such mainboards. You can get a better idea by looking at the acpi methods - look out for some other methods accessing very nearby registers. Oh, and have you checked whether there're also some gpio definitions in the acpi tables ? It's relatively new but some vendors already using it. --mtx -- --- Hinweis: unverschlüsselte E-Mails können leicht abgehört und manipuliert werden !
