asterisk users - Apr 2008 - OT - How to check HPET is on and working before installing Asterisk ?

Hi,

I would like to improve our installation process.
One of my requirement is to enable High Precision Event Timer support.

I'm working with Debian Lenny which is now 2.6.24-based.

Before installating Asterisk, zaptel and so on (and independently of those),
I would like to check HPET is on and working.

I ggogled and couldn't find anything useful on this.
Do you have any clue ?

Regards

$ zgrep HPET /proc/config.gz
CONFIG_HPET_TIMER=y
CONFIG_HPET=y
CONFIG_HPET_RTC_IRQ=y
CONFIG_HPET_MMAP=y

Or, if your config is not exposed under /proc, then this:

$ grep HPET /usr/src/linux/.config
CONFIG_HPET_TIMER=y
CONFIG_HPET=y
CONFIG_HPET_RTC_IRQ=y
CONFIG_HPET_MMAP=y

As a last resort, if the kernel's config is available under /proc and you
don't have the kernel source installed:

$ grep hpet /proc/timer_list 
Clock Event Device: hpet
 set_next_event: hpet_legacy_next_event
 set_mode:       hpet_legacy_set_mode

HPET showing up as not working means a kernel rebuild.

Most people build Zaptel as a module. Thus the above two will not show.
