Linux 5.9 Introducing A Multi-Color LED Framework


Recommended Posts

Longtime Linux kernel developer Pavel Machek has taken over as sole maintainer of the LED subsystem. For this first pull request going into Linux 5.9 is a big addition... The multi-color LED framework code has finally been merged.

 

This multi-color framework for the Linux kernel has been in the works by Texas Instruments and is about exposing clusters of colored LEDs as an array to user-space that it can then adjust the brightness of said cluster using a single file write. This approach still allows controlling the intensity of individual LEDs as part of the array/cluster and the benefit of the framework is being able to do so in a single write.

Am I misunderstanding this ? Is this just for LED light control ? @axipher

Right now it looks to just be Texas Instrument based LED driver chips which might be used in some computer peripherals and motherboards, but would be great for the DIY space in making your own controllers if there was a standard Linux Framework for it.

 

 

Once a standard framework is established, I would imagine that many other programmers would come forward to add support for other LED driver chips.

Ahh right that makes sense now, well it is another step in the right direction for Linux.
