=== Mind the gap - between real-time Linux and real-time theory ===

It is common to see RT Linux being used on research projects. However,
the assumptions made in papers are very often unrealistic. In contrast,
researchers argue that the latency metric, although useful, is an
oversimplification of the problem.

It is a consensus that the academic research helps to improve Linux’s
state-of-art, and vice versa. So how can we reduce the gap between these
task forces? The real-time researchers start papers with a clear
definition of the task model. But we do not have a task model for Linux:
this is where the gap is.

This talk presents effort on establishing the task model for the PREEMPT
RT Linux. Starting with the description of the operations that influence
the timing behavior of tasks, passing by the definition of the
relationships of the operations. Finally, the outcomes for Linux, like
new metrics and a model validator for the kernel, are discussed.
