hi to all,
i try to recompile my kernel 2.6.21.1 for best battery performance
i have enabled:
CONFIG_NO_HZ
CONFIG_HIGH_RES_TIMERS
CONFIG_HPET_TIMER
CONFIG_PREEMPT to low latency desktop
and timer frequency to 1000hz
is a good choice or i must select a more slow timer frequency?
when tickless works, the timer frequency no longer matters, so 1000 is
good.
why powertop on my centrino's laptop(sony vaio vgn-fs485b)
say that i don't enable hpet
support?
your bios probably doesn't enable it; there is a patch on the powertop
website to make linux enable it anyway...
