3.1 Linux, the real-time kernel
3.1.1 How to make Linux real-time
The first approach to improving Linux's real-time characteristics is to search the kernel for portions of code that take too long to execute, and insert explicit scheduling points. When the kernel encounters an explicit scheduling point, it can decide whether to finish executing the current process or hand over to a higher-priority task. This minimizes interrupt processing time or the scheduling of real-time tasks. Indeed, the length of the longest non-preemptive...
