Synopsis
irqbalance bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated irqbalance packages that fix one bug are now available for Red Hat
Enterprise Linux 6.5 Extended Update Support.
Description
The irqbalance packages provide a daemon that evenly distributes the interrupt
request (IRQ) load across multiple CPUs for enhanced performance.
This update fixes the following bug:
- Due to incorrect handling of the irq_info->load variable, the irqbalance
service in some cases incorrectly attempted to assign multiple high-load
interrupt requests (IRQs) in a single CPU, which caused a significant
performance decrease. With this update, the behaviors of the topo_obj->irq_count
and topo_obj->load variables have been adjusted so that high-load IRQs can be
evenly distributed among CPU. As a result, the described problem no longer
occurs. (BZ#1248640)
Users of irqbalance 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.
