Title:
Build cpupower from kernel tools
Status in “linux” package in Ubuntu:
Fix Committed
Bug description:
Ubuntu supplies the cpufrequtils package, which has been rendered
obsolete by cpupower. It is included in the kernel source as of
linux-3.1 [2], located at tools/power/cpupower/.
I don't think that it is explicitly tied to a particular kernel
version, so it may be best built separately from the kernel packages.
There is no consensus among other distributions: Fedora includes it in
their kernel-tools package; SuSE and RHEL pull from the git repo and
build as a separate cpupower or cpupowerutils package (similar to how
cpufrequtils was done); Arch takes it from the kernel source and
builds it along with other tools into separate packages.
cpupower provides a number of things that cpufrequtils does not, and
is invaluable in a server environment for tuning of power management.
Of particular note is the ability to set perf_bias on Intel
processors; I am not aware of another tool that can do this. It is
also the focus of power utility development, and should be available
on Ubuntu systems.
