I take that back. CPU hot-add (even if CPU is not present at boot time) works. I looked at C-states for that some time ago and it should only work if the hot-add event came in via ACPI events for CPUs which were not initialized at boot time. Better would be to initialize the first time it gets switched online.
I removed it from my TODO list, thanks :)
Anyway, making such stuff (cpufreq/cpuidle/...) more robust, is certainly a good idea.
Yes, that was the basic intent of my earlier patches that went into 3.9. It was all about simplifying it and making it robust.
And powernow-k8 does not exist anymore..., fortunately I didn't have to look at this stuff for some time.
Sure? Driver is still present in mainline.
BTW, i have given an initial fix for acpi-cpufreq (which should work) and waiting for Duncan to reply back. All other drivers don't set affected/related cpus directly, so they should be alright.
