Description Simon Lewis 2012-04-29 06:55:44 UTC

The package cpufrequtils has been replaced with kernel-tools.

For one application I use it is recommended to turn off CPU frequency throttling, quote:

"  you will probably want to turn off CPU frequency throttling when
   pianoteq is running, especially if you CPU is not very powerful. You
   can use the "cpufreq-info" command-line program to checks its current
   settings. CPU throttling can be disabled by the command:

     sudo cpufreq-set -c 0 -g performance (disable on the first cpu core)
     sudo cpufreq-set -c 1 -g performance (disable on the second core)
     ... (repeat for each CPU core)"

What would be the command using the new kernel tools, or is it possible to add a flag to the boot.conf?

sudo cpupower frequency-set -g performance

will set the governor for all cores.
