Red Hat Bugzilla – Bug 914623
cpupower set -m doesn't work
Last modified: 2013-11-20 23:39:48 EST
Description of problem:
cpupower set -m doesn't work. From the source code it seems this feature is not implemented, but the error message is misleading and can be wrongly interpreted as the feature is not supported by your platform.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. echo 0 > /sys/devices/system/cpu/sched_mc_power_savings; cat /sys/devices/system/cpu/sched_mc_power_savings
2. cpupower set -m 0
Error setting sched-mc not supported
I think it would be enough to change the message to something like:
Error setting sched-mc not implemented
or remove the feature entirely (upstream kernel drops the sched_mc_power_savings).
