RHBA-2015:1440 - cpuspeed bug fix update

Synopsis

cpuspeed bug fix update

Type/Severity

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 the speed of processors depending upon their current workload. These packages also allow users to enable CPU frequency scaling using in-kernel CPUfreq governors on Intel Centrino, AMD Athlon 64, and AMD Opteron platforms.

This update fixes the following bug:

  • A previous update brought in a change in the kernel introducing the intel_pstate driver, incompatible with how scaling was managed until Red Hat Enterprise Linux 6.7. Consequently, the cpuspeed service printed needless error messages during system boot and shutdown. With this update, platforms using intel_pstate support only the "performance" and "powersave" scaling governors, the default option and default state being "powersave". If the user has set a different governor from the above-mentioned, for example "ondemand" or "conservative", they have to edit the configuration and choose one from the two, "powersave" or "performance". In addition, needless error messages are no longer returned. (BZ#1196755, BZ#1211828, BZ#1219780, BZ#1225024)

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

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
