Hi everyone, I finally managed to run correctly Xenomai with acceptable
latencies (kernel 5.4.77 w ipipe patch2, linux Mint x86_64). Now I'm
starting to write some simple programs in order to practice. Is there an
API with lower latencies that I should use or it's just the same? I
programmed with RTAI API so the native API is quite familiar to me.
Best regards.

With Xenomai 3.x, the POSIX API delivers lower latency figures than
others: no intermediate layer there between the API and the core. We
should be talking about only a handful of µsecs better in non-debug
mode, though.
