Dunno if it’s an alternative but Linux had RT_PREEMPT and you can build a kernel that’s fully preemptable.

- sph 4y agoI just remembered that I've been running my desktop machine with `preempt=full` for a while now. I wonder why it's not the default for consumer distros yet.
- PaulDavisThe1st 4y agoIt's good, but ... there's "fully preemptable" and there's "fully preemptable". QNX is one of those, RT_PREEMPT kernels are the other.
