Chapter 13. Real-Time Kernel

The Red Hat Enterprise Linux for Real Time Kernel is designed to enable fine-tuning for systems with extremely high determinism requirements. The major increase in the consistency of results can, and should, be achieved by tuning the standard kernel. The real-time kernel enables gaining a small increase on top of increase achieved by tuning the standard kernel.

The real-time kernel is available in the rhel-7-server-rt-rpms repository. The Installation Guide contains the installation instructions and the rest of the documentation is available at Product Documentation for Red Hat Enterprise Linux for Real Time.

The kernel-rt sources have been upgraded to be based on the latest Red Hat Enterprise Linux kernel source tree, which provides a number of bug fixes and enhancements over the previous version. (BZ#1391779)
