Linux Kernel Developers Discussing Generic RGB LED Interface
Written by Michael Larabel in Hardware on 6 January 2019 at 12:15 AM EST. 10 Comments
With the ever increasing usage of RGB LEDs on modern computer systems, Linux kernel developers have begun discussing a formal RGB LED user-space interface.

To date RGB LED interface controllers supported by Linux have often exposed separate red/green/blue interfaces to user-space as separate LEDs while now there is a new discussion taking place regarding generic RGB LED support.

There is a desire to offer more user-space control over what's currently possible with RGB LED drivers, a desire to expose more information that might be available, and addressing various shortcomings of current RGB LED hardware. Those interested in the topic can learn more via this forum thread.
