I'd be proposing a 'ledtrig-thres' module which is totally independent of the G27, which would just provide the ability to light (or dark) a LED depending on a threshold and value. With a bit of extra code (in this module) multiple LEDs could be 'linked' to produce a bargraph, by automatically comparing the same value against their own thresholds. As to the hardware; it could be the G27, a single LED or a matrix of LEDs slung off one of the other LED subsystem devices. I'd want to show RPMs on my G27, but others could display CPU usage, emulate a VU meter/FFT display, have the 'low memory panic light' come on, etc... > simon> Once kernel framework is provided it should not need > simon> re-compilation on a case by case basis. > > If the kernel only provides a way to set the brightness of individual > LEDs, why can't you do the rest in userspace?

If well defined, lots of uses are possible.
