Mastering "Industrial Grade Linux" Challenges - Carsten Emde, OSADL

Industrial use cases of the Linux operating system and its real-time component Preempt-RT in particular face a unique technical challenge: While the strongholds of Linux-based systems, servers and smartphones, ship in high quantities with a relatively low variance of hardware and software features, the industrial area has to cope with a broad variety of hardware and software combinations each of which is shipped only in comparably low quantities.

The ability to handle a large variety of systems with an extremely high quality is one of the strengths of the Open Source development model, but it heavily depends on the feedback of the users which is difficult to obtain from an industrial environment. Alternatively, large-scale tests of similar systems can be carried out that certainly will expose common defects. But this is not sufficient as the past almost 10 years of exposure of the Linux kernel to the stress when running under real-time conditions have proven. To achieve "Industrial Grade Linux" quality it is necessary to expose the real-time Linux kernel to the most diverse set of hardware and software features. This exposure is necessary to guarantee the quality of the Linux Kernel for all involved parties, but none of the low-quantity Linux users can achieve that on their own.

The Open Source Automation Development Lab (OSADL) has started a collaborative effort years ago to put a broad variety of systems under test to fill the gap between the testing efforts of the high-quantity narrow use case and the low-quantity broad use case. The Preempt-RT developers have acknowledged the value of this effort, but they also are complaining about the shortcomings, which are mostly of non-technical nature.

All of this is a perfect reason to look at the achievements and the shortcomings and discuss possible solutions.
