Well put! People worked around something 10 years ago and this crap stays around forever! This userspace CPU frequency changes should not be possible, they are utterly bad. We need to enlighten people there, otherwise it sticks forever. It's like most distros (including my beloved gentoo), which ships stupid udev rules and other "patches" to improve things that are fixed for years. > > > > > > > And, the idea is that cpufreq module changes the freq (something it > already > > does), not to rewrite a new power policy. > > > > It does not.
