So those tie into the led subsystem? OK I did not expect that to be a thing, seems like that is what I need.

start with drivers/hwmon/ and if the developers there don't think that it should be there, let them tell you where to put it :) I will be on holiday until end of next week, I will send in the first 3 patches for fan support when I'm back home. I will add temps and LED later on. Maybe I will also add fan/pump speed curve, maybe.

Hello kernel newbies,

I am currently writing a driver for asetek 6th gen CPU coolers. Communication to these coolers goes via USB, but 3/4 (but not all!!) metrics are hwmon metrics. There is a case for either USB or hwmon but I don't know where I am supposed to put my driver. There is also the 1/4, RGB controls, these obviously don't fit in hwmon, but I don't know where to put these kinds of controls in the filesystem.

So those tie into the led subsystem?

If anyone could help me with these 2 choices I can start submitting my first code (I already have fan control working).

start with drivers/hwmon/ and if the developers there don't think that it should be there, let them tell you where to put it :)

Also, when submitting the driver, as it talks USB, be sure to cc: the linux-usb@vger.kernel.org mailing list to get those driver author's review.

good luck!
