在源码中,sched_ext可扩展调度类的使用,需要配置CONFIG_SCHED_CLASS_EXT,如果希望接入组调度的一些简单逻辑,则需要额外打开配置项CONFIG_EXT_GROUP_SCHED。 上图可以看出,sched_ext的核心实现,由bpf scheduler和core scheduler组成。core scheduler部分在内核态增加新的ext_sched_class调度类,提供与其它已有调度类相似的...

为了实现高性能并适应不同的场景,应该允许用户将定制的调度策略整合到生产环境中,例如,使用上游的"core scheduling"patch(将近 4KLOC 的代码修改)来修复潜在的性能问题。实际生产环境的经验还表明,在无服务器(Serverless)计算场景中,当容器部署密度较高时,通过应用新的负载平衡机制,CPU 调度开销可以从 6% 降低到 1.5...
