Have I said power doesn't matter on AC? Do you agree that a datacenter has different performance vs power tradeoff demands as a battery driven mobile device?
Back to the topic: As you did not answer on my (several) sysfs knob request(s), I expect you agree with it and will add one.
It's not only for real usage, but to give people a chance to easily test and get feedback on different HW.
Thanks,
Thomas
