LCA13: Networking - PREEMPT_RT session hosted by David A. Rusling, Linaro CTO. PREEMPT_RT is a set of maintained kernel patches supporting realtime operations. Historically, ARM platform support has 'bit-rotted' over time; there being a lack of ongoing testing and maintainance. As well as adding features, we need to bring PREEMPT_RT into a continuous integration loop. Other patchsets of interest to networking include NO_HZ_FULL. There may be some cross over with zero overhead Linux.
