Hey, In case you didn't know, the high res timers patch (which Ingo calls "a critical piece of RT infrastructure") has been merged into Ingo's RT preempt patch. So I think it's safe to assume it will be going in the mainline kernel too. This is great news for Linux audio as sub HZ timers enable lots of cool features. We will be able to send a MIDI clock that is as solid as you get from dedicated hardware. Lee
