ubuntu_preempt_rt

Enable real-time capabilities of the Linux kernel.

This repository includes shell scripts to

• configure,
• compile and
• install

a Linux kernel patched with PREEMPT_RT for running real-time applications under Ubuntu Linux.

Howto

1. Open up a terminal (STRG + ALT + T) and clone this repository git clone https://github.com/dtuchsch/ubuntu_preempt_rt.git.
2. Run sh configure.sh. This will download the linux kernel, apply the PREEMPT_RT patch and overwrite the kernel configuration file with the correct settings for a fully preemptible kernel (CONFIG_PREEMPT_RT_FULL=y).
3. Run the compilation shell script: sh compile.sh.
4. Install the Debian packages: sh install.sh.

Optional: If you want to adjust the kernel configuration change into the directory of the linux kernel (e.g. cd linux-3.18.11-rt7). Type make menuconfig to start the kernel configuration menu.

Optional: You may want to use your own kernel configuration file. For this, you need to uncomment the following line in configure.sh:

cp /boot/config-$(uname -r) .config

Comment out the following line:

cp rt-kernelconfig ${KERNEL}-rt/.config

Restart the configuration script:

sh configure.sh
