From plain Debian + Jack2 + MPD to Moode: doubts

[swizzle]

The 64-bit kernel already has preempt-rt applied.

Thanks for pointing this out.
So the 64-bit image is enabled for real-time/low-latency out-of-the-box, is it?
Are there processes using the real-time scheduling policy in Moode per your knowledge?

The 64-bit kernel is a configurable option rather than a separate image.

Traditionally certain privileged threads weren’t interruptible which could cause latency spikes if they didn’t finish before the scheduler wanted to switch to another process. The preempt-rt patch allows these threads to be preempted which lowers the latency of thread switching. All processes are affected by the way the scheduler works without anything needing to be done to them. Things like the rt threads used by mpd were an attempt to mitigate the uncertainty of the traditional behavior, it’s unlikely they cause any harm when everything is preempt-able but afaik shouldn’t be needed.
