RHBA-2013:1575 - Bug Fix Advisory
Synopsis
powertop bug fix and enhancement update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated powertop packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.
Description
PowerTOP is a tool to detect all the software components that make a computer
consume more than necessary power when idle. PowerTOP can be used to reduce
power usage by running various commands on the system.
The powertop package has been upgraded to upstream version 2.3, which provides a
number of bug fixes and enhancements over the previous version including
corrected handling of arbitrary interface names. Moreover, checks for usability
of the ondemand governor have been added. Also, several changes have been made
to enhance user experience and to simplify and improve power management
profiling capabilities. (BZ#682378, BZ#697273, BZ#829800)
This update also fixes the following bug:
- The default soft limit for per-process open file descriptors is 1024, and the
default hard limit for per-process file descriptors is 4096. By using the
performance counter subsystem, the PowerTOP tool could exceed the limit on
complex systems. Consequently, an error message about missing kernel support for
perf was displayed. This update adds a fix that temporarily increases both the
soft and hard file descriptor limits for the current process to the kernel
limit. If the kernel limit is still insufficient, PowerTOP now displays an error
message indicating that the file descriptor limits should be manually increased.
(BZ#998021)
Users of powertop are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
