Subject: Re: [Emc-developers] RtNet rt-preempt
RTnet only really works on 2.6 kernels. There was some work done for kernel 3.2
support but it wasn't usable. It's all EOL at this point and completely
useless, don't even think about RTnet anymore. Just use preempt-rt with POSIX
threads over the network. You will have the low-latency ethernet by using the
hm2_eth driver:
There was work being done on RT-Net for Xenomai, but unfortunately one of the
main developers Gilles Chanteperdrix died in 2016 and I think it is abandoned
at this point.

For info on how to configure and use hm2_eth please use:
$ man 9 hm2_eth
