I am working on a project that requires Preempt RT patch to Raspberry Pi.

How do I go about adding the latest patch to the latest kernel source?

I have referred to a few websites / tutorials, however they either seem to be broken on outdated.

About installing rtirq: try

apt-cache search rtirq

And if my memory serves me correctly, the installation is just:

apt-get install rtirq

Then head over to /etc/defaults/rtirq

or something similar (I'm not at a linux computer right now) and change the settings...

Finally, run

systemctl enable rtirq
systemctl start rtirq

and you should be set.

  • Hey @Mohtashim, Can you elaborate on the steps involving modification of rtirq? I am a beginner in this. Also, what is the difference between on rtirq and preempt rt? – Jahnavi Pinnamaneni Apr 16 '22 at 04:45
