Today we have RT Throttling; DEADLINE # servers should be able to replace and improve that." # # (Daniel Bristot de Oliveira, Peter Zijlstra, Joel Fernandes, Youssef # Esmat, Huang Shijie) # # - Preparatory changes for sched_ext integration: # - Use set_next_task(.first) where required # - Fix up set_next_task() implementations # - Clean up DL server vs. core sched # - Split up put_prev_task_balance() # - Rework pick_next_task() # - Combine the last put_prev_task() and the first set_next_task() # - Rework dl_server # - Add put_prev_task(.next) # # (Peter Zijlstra, with a fix by Tejun Heo) # # - Complete the EEVDF transition and refine EEVDF scheduling: # - Implement delayed dequeue # - Allow shorter slices to wakeup-preempt # - Use sched_attr::sched_runtime to set request/slice suggestion # - Document the new feature flags # - Remove unused and duplicate-functionality fields # - Simplify & unify pick_next_task_fair() # - Misc debuggability enhancements # # (Peter Zijlstra, with fixes/cleanups by Dietmar Eggemann, Valentin # Schneider and Chuyi Zhou) # # - Initialize the vruntime of a new task when it is first enqueued, # resulting in significant decrease in latency of newly woken tasks # (Zhang Qiao) # # - Introduce SM_IDLE and an idle re-entry fast-path in __schedule() # (K Prateek Nayak, Peter Zijlstra) # # - Clean up and clarify the usage of Clean up usage of rt_task() # (Qais Yousef) # # - Preempt SCHED_IDLE entities in strict cgroup hierarchies # (Tianchen Ding) # # - Clarify the documentation of time units for deadline scheduler # parameters (Christian Loehle) # # - Remove the HZ_BW chicken-bit feature flag introduced a year ago, # the original change seems to be working fine (Phil Auld) # # - Misc fixes and cleanups (Chen Yu, Dan Carpenter, Huang Shijie, # Peilin He, Qais Yousefm and Vincent Guittot) # # * tag 'sched-core-2024-09-19' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (64 commits) #
