One Line Summary

This talk will be a crash course into how to set up your environment using PREEMPT_RT Linux, explaining things like priorities for interrupts, how softirq's are done, using the priority inheritance mutexes, and other techniques required to avoid the gotcha's that real-time can get you with.

Abstract

There are a few flavors of real-time Linux out in the world. One of the most popular is the PREEMPT_RT kernel, which is slowly making its way into mainline Linux. In the past, I have given presentations describing what PREEMPT_RT does to Linux to make it real-time. But using PREEMPT_RT, you need to know a lot more than just the kernel. A real-time OS requires understanding everything from the hardware you use, the kernel, as well as the applications that sit on top. This talk will be a crash course into how to set up your environment using PREEMPT_RT Linux, explaining things like priorities for interrupts, how softirq’s are done, using the priority inheritance mutexes, and other techniques required to avoid the gotcha’s that real-time can get you with.
