Default cpuspeed: missing drivers ???

One problem I've discovered in cpuspeed is that there are drivers missing:

# cd /lib/modules/2.6.18-194.8.1.el5/kernel/drivers/cpufreq
# ll
total 72
-rwxr--r-- 1 root root 14408 Jul 1 21:40 cpufreq_conservative.ko
-rwxr--r-- 1 root root 16168 Jul 1 21:40 cpufreq_ondemand.ko
-rwxr--r-- 1 root root 7624 Jul 1 21:40 cpufreq_powersave.ko
-rwxr--r-- 1 root root 12524 Jul 1 21:40 cpufreq_stats.ko

Or is this what everyone has?

# uname -rmops
Linux 2.6.18-194.8.1.el5 i686 i686 GNU/Linux

No, as that is build into the kernel, rather than being build as a
loadable module.

# grep CPU_FREQ /boot/config-2.6.18-194.8.1.el5
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=m
CONFIG_CPU_FREQ_DEBUG=y
CONFIG_CPU_FREQ_STAT=m
CONFIG_CPU_FREQ_STAT_DETAILS=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m

Rob,

Thanks for the reply.

If you're running the same OS cpuspeed versions and on the same hardware
as I am, then something's amiss in distribution.

# cpuspeed --help 2>&1|head -1
cpuspeed v1.2.1


Plus, I would think we both should have cpufreq_performance.ko as it's
one of the drivers mentioned in the cpuspeed docs and manpage.

Initially I checked on my x86_64 workstation and thus sizes differed and
it had the additional file.
Now I check on my 32 bit laptop and see just the same four files, same
size as you have indicated.

Same version of cpuspeed.
I have a little monitor icon on my top panel that shows changes in cpuspeed.
It appears to work okay.
