[Xen-devel] [PATCH] xenpm control interface

["Lu, Guanqun" <guanqun.lu@xxxxxxxxx>]

This patch mainly adds cpu frequency control interface,
through which user can tune the parameters manually.

Now, xenpm can be invoked with the following options:
Usage:
       xenpm get-cpuidle-states [cpuid]: list cpu idle information on CPU cpuid 
or all CPUs.
       xenpm get-cpufreq-states [cpuid]: list cpu frequency information on CPU 
cpuid or all CPUs.
       xenpm get-cpufreq-para [cpuid]: list cpu frequency information on CPU 
cpuid or all CPUs.
       xenpm set-scaling-maxfreq <cpuid> <HZ>: set max cpu frequency <HZ> on 
CPU <cpuid>.
       xenpm set-scaling-minfreq <cpuid> <HZ>: set min cpu frequency <HZ> on 
CPU <cpuid>.
       xenpm set-scaling-governor <cpuid> <name>: set scaling governor on CPU 
<cpuid>.
       xenpm set-scaling-speed <cpuid> <num>: set scaling speed on CPU <cpuid>.
       xenpm set-sampling-rate <cpuid> <num>: set sampling rate on CPU <cpuid>.
       xenpm set-up-threshold <cpuid> <num>: set up threshold on CPU <cpuid>.

To ease the use of this tool, the shortcut option is supported,
i.e. `xenpm get-cpui' is equal to `xenpm get-cpuidle-states'.
