Re: rt_make_soft_real_time hangs my process

Can you provide the frequency of the hard7soft switches? 
If you a doing it for a controlled approach to Linux syscalls , try letting RTAI take care of it and see what happens. In such a view you might even try  using a Linux  server .
That said, eventually this is the case in which it should not be too complex to set a neutral test up, so that I cantry to diagnose the problem you are wittnessing.

Subject: [Rtai] rt_make_soft_real_time hangs my process

Hi all,

I’m running a shiny new system on Linux 4.1.18 w/ RTAI 5 from vulcano, and it seems to be going well.  (System is derived from a Slackware 14.1 install)

I seem to be having a small problem with one of my applications where it calls into rt_make_soft_real_time() which never returns.  It previously calls rt_make_hard_real_time(), and calls the pair in a loop, so it switches back and forth fairly frequently.

Any ideas?

-Duane
