http://bugs.archlinux.org/task/7135 requested a change in default
config to be able to use powertop utility, which is useful for laptop
users for tracking power-hungry apps.


From http://www.lesswatts.org/projects/powertop/faq.php :

What kernel options should I enable inside the kernel?

CONFIG_NO_HZ
CONFIG_HIGH_RES_TIMERS
CONFIG_HPET_TIMER
CONFIG_CPU_FREQ_GOV_ONDEMAND
CONFIG_USB_SUSPEND
CONFIG_SND_AC97_POWER_SAVE
CONFIG_TIMER_STATS

What kernel options should I disable inside the kernel?

CONFIG_IRQBALANCE
CONFIG_ACPI_DEBUG
