RHBA-2013:0490 - Bug Fix Advisory

Topic

Updated cpuspeed packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The cpuspeed packages contain a daemon that dynamically changes speed of
processors depending upon their current workload. This package also supports
enabling CPU frequency scaling via in-kernel CPUfreq governors on Intel Centrino
and AMD Athlon64/Opteron platforms.

This update also fixes the following bug:

• Previously, the cpuspeed daemon used a naive method of getting the highest

available scaling frequency. Consequently, on certain platforms, cpuspeed did
not set the CPU to the correct maximum limit. A patch has been provided to
address this issue and cpuspeed now sets the maximum speed correctly.
(BZ#876738)

Users of cpuspeed are advised to upgrade to these updated packages, which fix
this bug.
