Demystifying the linux cpu scheduler
WebCFS stands for “Completely Fair Scheduler,” and is the new “desktop” process scheduler implemented by Ingo Molnar and merged in Linux 2.6.23. It is the replacement for the previous vanilla scheduler’s SCHED_OTHER interactivity code.

WebScheduling process types in Linux such as real-time process and normal process. Different schedulers such as O (n) scheduler, O (1) scheduler, CFS scheduler and use of a red … WebThe scheduler is called either voluntarily by a thread leaving the processor, or involuntarily, to cause a preemption. Any currently executing thread can postpone the execution of the scheduler while running in the kernel context by either disabling preemption or the IRQs.
WebA task (i.e., a synonym for thread) is the minimal entity that Linux can schedule. However, it can also manage groups of threads, whole multi-threaded processes, and even all the processes of a given user. This design leads to the concept of schedulable entities, where tasks are grouped and managed by the scheduler as a whole. WebJan 17, 2014 · The current Linux kernel doesn't use this specific PPI timer for scheduling. It is only used as a delay loop time source. Instead the Global PPI timer is used. This timer can interrupt each CPU selectively, but the register set is global to all CPUs. A particular CPU may schedule an interrupt for itself; with the time base being global.
