Topic
Updated Red Hat Enterprise MRG Realtime packages that fix several bugs are now
available for Red Hat Enterprise MRG 2.4.
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 provides bug fixes for the following packages:
- The rt-firmware package contains the contents of the latest linux-firmware
tree from the kernel.org project for firmware blobs.
- The rt-setup package configures settings required by the Red Hat Enterprise
Linux real-time environment, such as creating the realtime group, adding
realtime user privileges to PAM (Pluggable Authentication Models), enabling the
configuration of kdump in real time, and disabling irqbalance by default.
Bug Fixes:
- Dracut was only looking at the default place for firmware files while creating
the initramfs image, while ignoring the firmware files provided by the
rt-firmware and kernel-rt-firmware packages. If the firmware for a device
required to boot the system was not at the default location, then the firmware
would be missing in the initramfs image that caused the device driver to fail at
boot time. Both the rt-firmware and rt-setup packages now carry minimal dracut
configuration files to make dracut aware of the alternative places for firmware
files. This allows the system to find the necessary firmware files to
successfully boot the system. (BZ#998920)
Users of the real-time capabilities of Red Hat Enterprise MRG 2.4, which is
layered on Red Hat Enterprise Linux 6, are advised to upgrade to these updated
packages, which fix these bugs.
