Open Source Summit + Embedded Linux Conference Europe 2020

Writing effective real-time applications requires controlling latency. On a general purpose operating system such as Linux, there are many things happening "under the hood" that can dramatically affect latencies within applications. However, Linux does provide interfaces to control and monitor the latencies of an application. In this session, John Ogness will cover the various sources of latency, show which APIs a real-time developer can (and should!) use to avoid them, and present mechanisms to verify the controlled latencies of an application.
