3.5. Getting a Real-Time Kernel in Fedora Linux

In Fedora Linux, the real-time kernel is provided by the Planet CCRMA at Home software repositories. Along with the warnings in the Planet CCRMA at Home chapter (see Section 4.2.2, “Security and Stability”), here is one more to consider: the real-time kernel is used by fewer people than the standard kernel, so it is less well-tested. The chances of something going wrong are relatively low, but be aware that using a real-time kernel increases the level of risk. Always leave a non-real-time option available, in case the real-time kernel stops working.
You can install the real-time kernel, along with other system optimizations, by following these instructions:
  1. Install the Planet CCRMA at Home repositories by following the instructions in Section 4.3.1, “Installing the Planet CCRMA at Home Repositories”.
  2. Run the following command in a terminal: su -c 'yum install planetccrma-core' Note that this is a meta-package, which does not install anything by itself, but causes a number of other packages to be installed, which will themselves perform the desired installation and optimization.
  3. Shut down and reboot your computer, to test the new kernel. If you decided to modify your GRUB configuration, be sure that you leave a non-real-time kernel available for use.
