    [$] The long road to lazy preemption

    Date:
    Fri, 18 Oct 2024 14:25:27 +0000

    Description:
    The kernel's CPU scheduler currently offers several preemption modes that implement a range of tradeoffs between system throughput and response time. Back in September 2023, a discussion
    on scheduling led to the concept of "lazy preemption", which could
    simplify scheduling in the kernel while providing better results. Things
    went quiet for a while, but lazy preemption has returned in the form of this patch series from Peter Zijlstra. While the concept appears to work well, there is
    still a fair amount of work to be done.
