HPET multimedia timer
Hi guys,
I've been fiddling with powertop on my notebook, and one of the
suggestions it makes is:
"enable the HPET (Multimedia Timer) in your BIOS or add the kernel patch
to force-enable HPET. HPET support allows Linux to have much longer
sleep intervals."
I checked that the kernel has HPET support built in:
CONFIG_HPET_TIMER=y
CONFIG_HPET=y
# CONFIG_HPET_RTC_IRQ is not set
CONFIG_HPET_MMAP=yes
This is on a custom built kernel, however, I used the Debian
linux-source package for 2.6.21 and the running config and only disabled
CONFIG_PARAVIRT to enable the ATi module to build. The rest of the
config is unchanged.
My bios doesn't have any settings in for HPET (It doesn't have much more
than boot order). Is there anything else I have to do to make the HPET
work?
Thanks
