cpuspeed: CPU frequency adjusting daemon
- Summary
- cpuspeed is a daemon that dynamically changes the speed
of your processor(s) depending upon its current workload
if it is capable (needs Intel Speedstep, AMD PowerNow!,
or similar support).
This package also supports enabling cpu frequency scaling
via in-kernel governors on Intel Centrino and AMD
Athlon64/Opteron platforms.
Changelog
- * Mon Mar 30 17:00:00 2009 Jarod Wilson <jarod{%}redhat{*}com> 1.2.1-7
- Handle case under kernel-xen where xm is unavailable and/or
we can't communicate with xend (additional fix for #488924)
- * Thu Mar 19 17:00:00 2009 Jarod Wilson <jarod{%}redhat{*}com> 1.2.1-6
- Don't try loading speedstep-centrino if acpi-cpufreq already
successfully loaded, it causes p-state issues (#485480)
- If we're running on a Xen kernel and the number of virtual cpus
doesn't match the number of physical cpus, we could end up
scaling the wrong physical cpu due to migration, so in the
vcpus != pcpus case, don't do freq scaling (#488924)
- * Wed Sep 24 17:00:00 2008 Jarod Wilson <jarod{%}redhat{*}com> 1.2.1-5
- Support for speedstep-centrino module fallback if
new-and-improved acpi-cpufreq doesn't work (#463488)
