I wonder if authors considered using a real-time patch of Linux such as PREEMPT_RT [1] or Xenomai [2] ? [1]: https://rt.wiki.kernel.org/index.php/CONFIG_PREEMP

- epickrram 11y agoWe did look at trying out a real-time kernel, but decided that if we could achieve tolerable latencies with a stock kernel + tunings, then that would be preferable. When ~2us jitter becomes an issue, we'll revisit our options, and no doubt share our findings. Thanks for the link to Xenomai, I hadn't come across it before.
