Re: Should there be an option to disable Powermizer?
I've never had any problem getting the modprobe.d options to work - I suspect anyone who does have trouble is not defining them in the location appropriate for their distro.
But you missed the whole point of my post...
I was making people aware of other values for the PerfLevelSrc registry option (regardless of where/how you define it). I've only ever seen people suggest the 0x2222 value which disables powermizer completely. That's not always ideal. Wanna disable frequency scaling on AC only, but re-enable it when unplugged to save battery life? Use PerfLevelSrc=0x3322 instead.
