Merged last week for the Linux 7.2 kernel were all of the sched_ext changes for this extensible scheduler support that allows loading BPF programs from user-space for handling scheduling tasks. Linux 7.2 continues building out sched_ext's sub-scheduler support...

A change to the Linux kernel's extensible scheduler class "sched_ext" for allowing nifty scheduler implementations via BPF programs will begin to prioritize SMT siblings to help with better performance...

Just days after the Linux 7.1-rc1 kernel release, the Linux kernel's extensible scheduler class "sched_ext" is seeing a lot of bug fixes. Many of these bug fixes aren't just from the Linux 7.1 merge window but a number date back many kernel cycles. This uptick in bug fixes for sched_ext is coming due to increased AI code review...

Sched_ext as the extensible scheduler code for the Linux kernel that allows loading schedulers from user-space via eBPF code has shown a lot of interesting possibilities. Andrea Righi of NVIDIA who has been heavily involved in sched_ext development shared some of the future plans being looked at as we move into 2026...

The Linux kernel's innovative sched_ext code for being able to easily write extensible task schedulers using eBPF programs has some nice enhancements merged for Linux 6.19...

Merged last year for the Linux 6.12 kernel was sched_ext for allowing extensible scheduler possibilities by allowing schedulers to be implemented as eBPF code and dynamically loaded into the kernel. This allows for rapidly developing new schedulers as well as exploring other new possibilities around more intelligent kernel scheduling decisions. Meta, Google, Canonical (Ubuntu), and others have been big proponents of sched_ext and NVIDIA is also increasingly vocalizing their support for these extensible scheduler opportunities...

The Infinity Scheduler is another attempt at improving the CPU scheduling behavior under Linux and created by the developer behind the existing "scx_flow" sched_ext scheduler. But Infinity Scheduler isn't taking the approach of using sched_ext and is rather patched into the Linux kernel in modifying CFS and RT behavior...

The extensible scheduler "sched_ext" code for allowing Linux scheduling behavior to be defined via BPF programs is seeing some useful improvements with the in-development Linux 7.1 kernel...

The sched_ext scheduler framework that allows creating kernel thread schedulers via BPF programs is ready with some updates for the Linux 6.18 kernel...

The sched_ext code for extensible scheduler support and being able to quickly prototype new Linux kernel scheduling improvements continues evolving nicely since its much anticipated merging to the mainline kernel in 2024. Ahead of the imminent Linux 6.15 merge window, the sched_ext feature updates were sent out today for this next kernel cycle...

As expected, minutes ago Linus Torvalds just released the Linux 6.12 kernel as stable. Linux 6.12 brings many new features, new hardware support, and is rounded out by the fact of expected to become this year's Long Term Support (LTS) kernel version...

One of the niftiest kernel innovations to be upstreamed into Linux over the past year was sched_ext for extensible scheduler behavior in allowing kernel schedulers to be implemented via BPG programs. Sched_ext can allow for interesting scheduler improvements with a variety of use-cases and showed much potential even before being upstreamed. The work on sched_ext isn't yet over though and yet more improvements landed for Linux 6.16...
