RHEA-2015:0588 - Product Enhancement Advisory

Topic

New kernel-rt packages are now available for Red Hat Enterprise Linux 7.

Description

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. The Real-Time (RT) kernel is the Red Hat Enterprise Linux kernel with the PREEMPT_RT changes applied, which makes the kernel into a platform for running real-time applications. These applications have critical timing constraints that are either periodic or deadline-oriented.

This enhancement update adds the kernel-rt packages to Red Hat Enterprise Linux 7, which allows for development of applications geared towards deterministic workloads, and enables user applications to run with consistent response times, as well as to avoid in-kernel priority inversion. (BZ#1151560)

Note that the RT feature is not an inherent part of Red Hat Enterprise Linux 7, and has to be purchased separately.

All users who require kernel-rt are advised to install these new packages. The system must be rebooted for this update to take effect.
