cpuspeed init script should allow user setting minimum and maximum frequency
Last modified: 2007-11-30 17:11:02 EST
Description of problem:
The init scipt for cpuspeed should allow user to set minimum and maximum
frequency. Pentium 4 CPUs allow scaling down to 12%, which makes them a bit
unresponsive in GUI. I wish to be able a minimum like 500MHz for scaling.
This can be done by adding something like the follwoing lines before starting
echo MIN_FREQ > /sys/class/system/cpu/cpu0/cpufreq/scaling_min_freq
echo MAX_FREQ > /sys/class/system/cpu/cpu0/cpufreq/scaling_max_freq
or taylored a bit to support multiple CPU systems, but IIRC cpufreq does not
support SMP yet, so this sould be enough.
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.
Latest rawhide builds enable this functionality.
