RHBA-2015:2581 - Bug Fix Advisory

Topic

Updated Red Hat Enterprise MRG Realtime packages that add one enhancement are
now available for Red Hat Enterprise MRG 2.5.

Description

MRG Realtime provides the highest levels of predictability for consistent
low-latency response times to meet the needs of time-sensitive workloads. MRG
Realtime provides new levels of determinism by optimizing lengthy kernel code
paths to ensure that they do not become bottlenecks. This allows for better
prioritization of applications, resulting in consistent, predictable response
times for high-priority applications. This update adds the following bug fix:

• The rt-tests package includes a set of programs that test and measure various

components of real-time kernel behavior. This package measures timer, signal,
and hardware latency and tests the functioning of priority-inheritance mutexes.
With this update, a new upstream package with the latest bug fixes is available.
(BZ#1243516)

Users of the real-time capabilities of Red Hat Enterprise MRG 2.5, which is
layered on Red Hat Enterprise Linux 6, are advised to upgrade to these updated
packages which add this enhancement.
