Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated Red Hat Enterprise MRG Realtime packages that add one enhancement are
now available for Red Hat Enterprise MRG 2.5.
Description
Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT
infrastructure for enterprise computing. MRG offers increased performance,
reliability, interoperability, and faster computing for enterprise customers.
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
enhancements:
- The contents of the rt-firmware package was updated to provide current
firmware files from the latest linux-firmware tree in the kernel.org project and
from Red Hat Enterprise Linux. (BZ#1184251)
- 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 several enhancements is available,
including an updated cyclictest program that has a 'tracemark' feature for use
with ftrace tracing. (BZ#1186427)
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.
