Testing the real-time Kernel on Arbitrary Hardware.
Session information has not yet been published for this event.
One Line Summary
An exploration of tools and test suites for measuring the performance of the real-time kernel. Also, a glimpse into the future, what do we need to do better?
Abstract
How is the performance of the real-time kernel measured? What do we mean we talk about real-time performance? Does it still perform well and offer guarantees of low-latency and determinism when a system is stressed? An in-depth exploration of the rt-test suite, including cyclictest and related programs. We also discuss rteval, which simultaneously runs various benchmarks and the rt-tests suite in order to stress the kernel and shake out problems. Also, a glimpse into the future. What is being worked on currently? What do we need to do better?
