> The real-time community around Linux has been responsible for
> important changes in the kernel over the last few decades.
> Preemptive mode, high-resolution timers, threaded IRQs,
> sleeping locks, tracing, deadline scheduling and formal
> tracing analysis are integral parts of the kernel rooted
> in real-time efforts, mainly from the PREEMPT_RT patch set.
> The real-time and low-latency properties of Linux has
> enabled a series of modern use cases, like low-latency
> network communication with NFV and the use of Linux in
> safety-critical systems.
> 
> This MC is the space for the community to discuss the advances of
> Linux in real-time and low latency features. For example
> (but not limited to):
> 
> - Bits left for the PREEMPT_RT merge
> - Advances in the fully preemptive mode
> - CPU isolation (mainly about how to make it dynamic)
> - Tools for PREEMPT_RT and low latency analysis
> - Tools for detecting non-optimal usages of the PREEMPT_RT
> - Improvement on locks non-protected for priority inversion
> - General improvements for locking
> - General improvements for scheduling
> - Other RT operating systems that run in parallel
>   with Linux and the integration with Linux (e.g., Xenomai).
> - Real-time virtualization
> 
> Examples of topics that the community discussed over the
> last years that made progress in the RT MC:
> 
> - timerlat/osnoise tracers and RTLA
> - DL server for starvation avoidance
> - Proxy execution (still under discussion)
> - Tracing improvements - for example, to trace IPIs
> 
> It is important to notice that it is not _only_ about PREEMPT_RT,
> but anything related to real-time and low latency. For instance,
> CPU isolation, real-time scheduling, timers, other OSs that
> run in parallel... and so on.
> 
> Join us to discuss the future of real-time and low-latency Linux.

> This email has a list of people in Bcc, based on a list of
> commit authors in sched/locking/power/time. It is far from being
> complete. So, please forward this message to the people on
> your team working on scheduling-related topics.
