Bets for 6.12: sched_ext, PREEMPT_RT anyone?
- samtheprogram 2y agoPREEMPT_RT, please!!
- cwillu 2y agoPREEMPT_RT would be a boon for audio/video work, hope it finally goes in. Not everyone who needs it knows they need it, let alone how to compile it, and having it in-tree would massively simplify the process for distros to [re-]package a proper RT kernel.
- anthk 2y agoThese kind of schedulers often harm servers' I/O usage. And the opposite it's true too. Server based loads are bad for multimedia/gaming desktops.
- cwillu 2y agoYes, that's why it's a config option; but if the code is in the kernel a distro can package up a preempt-rt kernel by flipping the config flag rather than maintaining an out-of-tree patchset, which is a _much_ lower burden.
- anthk 2y agoAh, TIL. I thought the -rt kernel was in mainline since mid 2000's.
- aseipp 2y agoThere's already a series posted a week ago for 6.12 that will ungate PREEMPT_RT on x86, ARM and RISC-V; it only modifies the Kconfig entries to enable it[1]. So I'd say it's hardly a bet! [1] https://lwn.net/ml/all/20240906111841.562402-1-bigeasy@linutronix.de/ https://lwn.net/ml/all/20240906111841.562402-1-bigeasy@linut...
