The Past, Present and Future of Linux Real-Time - Thomas Gleixner, linutronix GmbH

Providing Real-Time capabilities to a general purpose Operating System is an outstanding technical problem. Efforts to reach this goal for the Linux Kernel date back into the mid 1990's and have been accompanied by passionate mostly academic debates about the correct
approach. All these efforts took place mostly disconnected from the mainline kernel community.

Almost 10 years ago, a new project emerged to bring Real-Time capabilities to the Linux Kernel: Preempt-RT. For the first time a couple of well recognized mainline kernel developers, heavily influenced by one of the visionary academic masterminds, took on the challenge with a clear focus to integrate the technology into the
mainline kernel.

A good reason to take a tour through the history of Linux Real-Time and the benefits which were brought to the mainline kernel by the Preempt-RT project.

While Linux Real-Time is primarily a deep technical problem, the Preempt-RT project had and still has to master some interesting non-technical challenges, which are crucial prerequisites for the technical success of the project. Analysing the present state and giving an outlook on the future of Preempt-RT will focus on the non-technical issues and discuss possible solutions.
