Description David Rees 2008-06-30 18:59:48 UTC
Description of problem:
The settings specified in /etc/sysconfig/cpuspeed aren't reflected by the
ondemand governor after boot up.

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
1. Boot up a system which supports kernel based CPU frequency changing.
2. Check the value of
/sys/devices/system/cpu/cpu0/cpufreq/ondemand/ignore_nice_load. If it matches
IGNORE_NICE in /etc/sysconfig/cpuspeed, change it and reboot. It will not match
after the change, if it was not already mismatched (it is mismatched by default
on AMD systems I've tested).
Actual results:
If IGNORE_NICE is set to 0,
/sys/devices/system/cpu/cpu0/cpufreq/ondemand/ignore_nice_load is set to 1 after

Expected results:
If IGNORE_NICE is set to 0,
/sys/devices/system/cpu/cpu0/cpufreq/ondemand/ignore_nice_load is set to 0 after

Additional info:
I suspect that either the cpufreq modules are getting loaded before cpuspeed is
started, or the governor is getting reloaded after cpuspeed is started. If you
restart cpuspeed the correct settings are set.

There's a dupe bug around here somewhere... Its actually gnome's cpufreq applet
that stomps on that setting. We do the right thing, then when gnome starts up,
it bludgeons everything. :\

Hmm, I think you're right. I found a system which supports cpufreq but boots in
to run level 3 and it seems to be OK.
