I started with a standard= ubuntu 20.04 installation and build a kernel from ,v5.15.y-evl-rebase' bra= nch with evl enabled and things that ,evl check -file' told me disabled.=20 Good news: the kernel runs and I do have a evl api. Bad news: latmus tells me a worst jitter of 500=B5s right away. Also ,evl test' tells me: *** stack smashing detected ***: terminated Aborted (core dumped) ** poll-multiple: BROKEN I have a Xenomai3 setup on this same machine that has a 30=B5s jitter.=20 On the evlproject.org site there is a list of ports including a x86_64 atom= with all the boxes checked. Is there anywhere more information about these= ports, are the .config files somewhere to be found, to be used as a starti= ng point? I'm also interested in the Raspberry PI port, but I don't like to= try it all out again for myself, a kernel-config or in case of the PI even= a binary or a hole Image would be great! Also I'm kind of lost on documentation, all I find leads back to the evlpro= ject.org main site. Where can I find what to do if say "poll-multible" fail= ed? I have the feeling I am still missing a big junk of documentation! Can = anyone please point me at it! Thank you Peter Steub
