The Real-time microconference focuses on finishing the last lap of getting the PREEMPT_RT[1] patch set into mainline. Many of these missing pieces, however, are not at the core of real-time features (like locking, and scheduling), but instead, on other subsystems that compose the kernel, like file systems and memory management. Making this Linux subsystems compatible with PREEMPT_RT requires finding a solution that is acceptable by subsystem maintainer, without having these subsystems suffer from performance or complexity issues. Suggested Topics: - New tools for PREEMPT_RT analysis [2]. - How do we teach the rest of the kernel developers how not to break PREEMPT_RT? - Stable maintainers tools discussion & improvements: [3] - The usage of PREEMPT_RT on safety-critical systems: what do we need to do? - Make NAPI and the kernel-rt working better together [5] - Migrate disable and the problems that they cause on rt tasks [6] - It is time to discuss the "BKL"-like style of our preempt/bh/irq_disable() synchronization functions. - How do we close the documentation gap - The status of the merge, and how can we resolve the last issues that block the merge - Invite the developers of the areas where patches are still under discussion to help to find an agreement - How can we improve the testing of the -rt, to follow the problems raised as Linus tree advances? - What’s next? If you are interested in participating in this microconference and have topics to propose, please use the LPC CfP process, and select "Real-time MC" for the "Track". More topics will be added based on CfP for LPC microconference.
