Over the past decade, many parts of PREEMPT_RT have been included in the official Linux codebase. Examples include real-time mutexes, high-resolution timers, lockdep, ftrace, RCU_PREEMPT, threaded interrupt handlers and more. The number of patches that need integration has been significantly reduced, and the rest is mature enough to make their way into mainline Linux. The scheduler is the core of Linux performance. With different topologies and workloads, it is not an easy task to give the user the best experience possible, from low latency to high throughput, and from small power-constrained devices to HPC. In the last years, the real-time and scheduling microconferences helped in the The Real-time Linux Analysis tool merge [1], progress on the full mainline merge of the PREEMPT_RT, core scheduling merge and to promote the progress in the latency nice scheduling feature [3]. If you are interested in participating in this microconference and have topics to propose, please use the LPC CfP process [4], and select "Real-time and Scheduling" for the "Track". A non exhaustive list of potential topics is: - How to scale PREEMPT_RT for very-large systems - Improve overall system partitioning for real-time HPC workloads - Latency nice scheduling feature - Better support/heuristics for new processors - New tools for PREEMPT_RT analysis. - How do we teach the rest of the kernel developers how not to break PREEMPT_RT? - The usage of PREEMPT_RT on safety-critical systems: what do we need to do? - The merge's status, and how can we resolve the last issues that block the merge. - What’s next? The submission deadline is June 30. Come and join us in the discussion, we hope to see you there!
