This look good,
only thing is that hp-wmi driver need a cool profile (Emphasises the computer
cool to touch), if you can add it would be perfect.

Is low-power is different to cool? I figured low-power was going to be cool so combined them.
I could call it low-power-cool if that helps? It seems a little clunky but not too bad. I'm sure the user space folks can put sunglasses on it or something ;)

IIRC we already had this discussion, cool means cool-to-touch, so could be done by
e.g. extra aggressive ramping up of the fans, so this is not necessarily the same
as low-power.

Yes this is all somewhat confusing. Luckily (for us kernel folks) we have already
sorta decided to just use the profile-names from the vendors more or less as is and
leave figuring this out further to userspace.

The reason to use the enum + try to have a fixed list of choices is to try and
limit the proliferation of profile-names to keep things somewhat manageable.

But as I discussed previously with Elia (*) we really need all 3 of low-power
cool and quiet.

Regards,

Hans



*) I was coming at this discussion from the same angle you (Mark) are

OK, I can add a cool option.

I'll get that out later today (unless Elia corrects me :))

Thanks all
Mark
