tsg1zzn,
Yes, CPU frequency scaling is enabled and working. Here is everything I
did after you asked me about it:
1. Enabled the CPU frequency scaling panel applet. It showed 1GHz for
each of the two CPUs.
2. Wrote a very simple/stupid C program (because that's the easiest
thing I could think of to push the CPU) which basically did this:
#include <stdio.h>
int main (void)
{
int i, j;
for (i = 0; ; i++) {
j++;
}
return 0;
}
and built and ran it:
$> make 1 && ./1
3. On running that program the CPU frequency in the panel applet jumped
to 1.67GHz.
4. Stopping the program (CTL-C) caused the CPU frequency to fall back to
1GHz.
That said, I also ran these two commands and got the associated output:
$> cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
1667000 1333000 1000000
$> cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_available_frequencies
1667000 1333000 1000000
$> cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
conservative ondemand userspace powersave performance
$> cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_available_governors
conservative ondemand userspace powersave performance
Let me know what other information I should publish here.
Regards
Mahesh
