RHBA-2012:1404 - cpuspeed bug fix update

Synopsis

cpuspeed bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated cpuspeed packages that fix four bugs are now available for Red Hat Enterprise Linux 6.

Description

The cpuspeed packages provide a daemon to manage the CPU frequency scaling.

This update fixes the following bugs:

• Prior to this update, the PCC driver used the “userspace” governor was loaded instead of the “ondemand” governor when loading. This update modifies the init script to also check the PCC driver. (BZ#642838)

• Prior to this update, the cpuspeed init script tried to set cpufrequency system files on a per core basis which was a deprecated procedure. This update sets thresholds globally. (BZ#738463)

• Prior to this update, the cpuspeed tool did not reset MIN and MAX values, when the configuration file was emptied. As a consequence, the MIN_SPEED or MAX_SPEED values were not reset as expected. This update adds conditionals in the init script to check these values. Now, the MIN_SPEED or MAX_SPEED values are reset as expected. (BZ#616976)

• Prior to this update, the init script did not handle the IGNORE_NICE parameter as expected. As a consequence, "-n" was added to command options when the IGNORE_NICE parameter was set. This update modifies the init script to stop adding the NICE option when using the IGNORE_NICE parameter.(BZ#797055)

All users of cpuspeed are advised to upgrade to these updated packages, which fix these bugs.
