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 at the core of Linux performance. With different topologies and workloads, giving the user the best experience possible is challenging, from low latency to high throughput and from small power-constrained devices to HPC, where CPU isolation is critical. The following accomplishments have been made as a result of last year’s micro-conference: - Progress on rtla/osnoise to support any workload [1] - Progress on adding tracepoints for IPI [2] - Improvements in RCU to reduce noise - Progress on the latency-nice patch set [3] Ideas of topics to be discussed include (but are not limited to): - Improve responsiveness for CFS tasks - e.g., latency-nice patch - The new EEVDF scheduler proposal [4] - Impact of new topology on CFS including hybrid or heterogeneous system - Taking into account task profile with IPCC or uclamp - Improvements in CPU Isolation - The status of PREEMPT_RT - Locking improvements - e.g., proxy execution [5] - Improvements on SCHED_DEADLINE - Tooling for debugging scheduling and real-time It is fine if you have a new topic that is not on the list. People are encouraged to submit any topic related to real-time and scheduling. Please consider that the goal is to discuss open problems, preferably with patch set submissions already in discussion on LKML. The presentations are very short, and the main portion of the time should be given to the debate - thus, the importance of having an open and relevant problem, with people in the community engaged in the solution. Submissions are made via LPC submission systems, selecting *Track Real-time and Scheduling MC* Please, forward this email for people interested on this subject (it not easy to build the Cc: list for this email without forgetting important people :-))!
