Board Farm APIs for Automated Testing of Embedded Linux - Tim Bird, Sony & Harish Bansal, Timesys
For years, designers of automated testing systems have used ad-hoc designs for the interfaces between a test, the test framework and board farm software, and the device under test. This has resulted in a situation where hardware tests cannot be reused from one lab to another. This talk presents a proposal for a standard API between automated tests and board farm management software. The idea is to allow a test to query the farm about available bus connections, attached hardware and monitors, and other test installation infrastructure. The test can then allocate and use that hardware, in a lab-independent fashion. The proposal calls for a dual REST/command-line API, with support for discovery, control and operation - of hardware and network resources. It is hoped that establishing a standard in this area will allow for the creation of an ecosystem of shareable hardware tests and board farm software.

Deploying Linux in Safety Critical Applications - Three Key Challenges - Christopher Temple, Arm Germany GmbH
The next wave of highly automated and highly dependable automotive and industrial systems are driving a strong desire to deploy Linux in such systems. While dependability attributes like availability, safety and maintainability have already received attention in existing application domains like cloud computing the safety aspect is new. The safety aspect for Linux revolves around three key challenges. Firstly, the OS needs to provide specific services with sufficient safety properties to the safety application. Secondly, the OS needs to show intrinsic safety in a way that the OS itself does not become a source of hazardous operation. Thirdly, the OS needs to be able to interface adequately to underlying safety hardware such that safety properties provided by the hardware are enabled and maintained, and no new uncovered safety issues are introduced. The presentation will discuss issues and ideas around identifying sufficient safety properties, the challenges and potential solutions around intrinsic safety, and the state-of-the-art around safety enabled hardware and related integration needs in light of different application classes.
