I'm running with Ubuntu 14.04 on a Power8 server.
Is there a way to tell how fast the processors are running?
How do I enable the tools that come with powerpc-utils and cpufreq ?

ppc64_cpu
reports
# ppc64_cpu --frequency
min: 3.693 GHz (cpu 159)
max: 3.693 GHz (cpu 1)
avg: 3.693 GHz
the output of 'cpufreq-info' shows (example for one core):
analyzing CPU 159:
driver: powernv-cpufreq
CPUs which run at the same hardware frequency: 152 153 154 155 156 157 158 159
CPUs which need to have their frequency coordinated by software: 152 153 154 155 156 157 158 159
maximum transition latency: 4294.55 ms.
hardware limits: 2.06 GHz - 3.69 GHz
available frequency steps: 3.69 GHz <clipped>, 2.09 GHz, 2.06 GHz
available cpufreq governors: conservative, userspace, powersave, ondemand, performance
current policy: frequency should be within 2.06 GHz and 3.69 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 2.06 GHz (asserted by call to hardware).
cpufreq stats: 3.69 GHz:0.66%, 3.66 GHz:0.00%, 3.62 GHz:0.00% <clipped> 2.09 GHz:0.00%, 2.06 GHz:99.34% (5)
Here we can see the CPU is still clocked at ~2GHz and the governor is "ondemand" so nothing has changed. This Ubuntu installation is fully up to date
