Red Hat Bugzilla – Bug 842190

Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Sorry, I hit enter on accident when filling out the title and it submitted the form before I could describe the bug. It's not a big deal, but I'd suggest clarifying how to enable a governor in section 3.2.2. Right now it's a bit unclear how to enable a particular governer. All it says is enter the following command:
echo [governor] > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
This is unclear to me because my first thought was to use "cpufreq_powersave" (or whatever governor I wanted to use) in place of [governor]. However, this didn't work and gave me the following error:
bash: echo: write error: Invalid argument
After googling I found the correct command to be the following:
echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Maybe an example would help clarify how to do this correctly.
For reference, here's the page I was using:
Thanks for reporting this. I've updated Procedure 3.2 in commit d36218d91d98182861ddb5ebad0b37e8cca2f08b
As you suggested, I've given an example to illustrate what part of the full governor name is required in the command.
