Sure, but we need to set one afaics because... > Whilst we are in the initscripts we *should* be at 100% utilization on > as many CPUs as we have for speed, so power saving doesn't really apply. ...we are I/O bound often during startup afaics (at least these days) and the CPU is often fast enough when on lower frequency. Currently the default kernel gov is userspace: $ grep DEFAULT_GOV /boot/config-2.6.20-1.2997.fc7 # CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y So no power savings until something takes care of it afaics (or am I wrong with that? anyway, that could probably easily be adjusted until F8).
