Hi Alexis,
thanks so much for the new feature! I will try it and report back.
In the last months, I actually did run some comparisons between Comedi and
Analogy, and in all cases found that your Analogy implementation performs
exactly the same as Comedi, actually, for CMD-based streaming, I noticed
shorter latencies in Analogy. I also couldn't find any Comedi functionality
(for our problems) that was missing in Analogy. Thus, for our work, there may
simply be an issue that the communication protocol we are porting from vxWorks
may not easily be implemented with our NI6259 board using either Comedi or
Analogy, and we are considering to change the protocol with the help of some
intermediate electronics. After all is working, I will email the method of
solution to the xenomai-core list.
But I am eager to check your new functions.
Best wishes,
-Stefan

Hi Stefan,
A few months ago, you asked me whether it was possible to prevent the
OS from waking up your process each time a few bytes were
acquired. You came with the idea to implement a wake-up threshold below
which the user space process is kept in sleep state.
A few days ago, I updated my experimental branch: two new user-space
functions were added: a4l_set_wakesize() and
a4l_get_wakesize(). Thanks to them, you will be able to configure the
wished behaviour.
I hope this will help you.
