Internals of the RT Patch
Over the past few years, Ingo Molnar and others have worked diligently to turn the Linux kernel into a viable Real-Time platform. Today it is reaching maturity and is making its way into the upstream kernel. Commercial companies are placing more pressure on distributions to offer a Real-Time Linux variant. This talk will explain the technical aspect of the RT Patch, from threaded interrupt handlers to sleeping spin locks and the effect that priority inheritance has on the system, as well as what to watch out for when developing in a Real-Time environment.
The presentation will end with benchmarks that will show the benefits the RT patch gives to Linux. Not just comparing the RT patch with the most current versions of Linux, but also showing the improvements between the different versions of the upstream kernel and how the parts of the RT patch that made it into mainline have already improved Linux.
