Experimental Physics and
Industrial Control System

Dear Vijay,
thank you very much for your effort to bring some order here ;-)

I am currently trying to get EPICS to work on RTEMS6 as well.

I already failed with the legacy stack because configuration variables like
RTEMS_HAS_NETWORK are not set with the waf-builder. 

That's why I quite happily jumped on your legacy-net-extra 

(For the beatnik CPU on which I can test directly on the hardware).

Unfortunately, it doesn't quite work yet:

cd rsb
cd rtems

Hello all,

In RTEMS 6, there will be no cpukit/libnetworking in the RTEMS repository and it will be moved to its own separate repository. There are ongoing efforts in this direction and it is very close to completion. What's remaining, is to collect feedback from the users of the libnetworking stack.

I request you to test the new standalone legacy networking repository with your regular targets and let me know if I have broken something in RTEMS or in the new repository. The legacy repo, in its current state, has been tested with pc-qemu and it can successfully run the legacy networking tests.

The following are the links to the repositories with the latest version of changes:
RTEMS: https://git.rtems.org/vijay/rtems.git/log/?h=devel-no-libnet
Legacy Network: https://git.rtems.org/vijay/rtems-net-legacy.git/log/?h=main

The following BSP family in RTEMS has been used with the old legacy networking stack:
Zynq, PC, Motorola Shared, Beatnik, mvme3100, mvme5500, gen68360, uc5282, mvme 162/167

If anyone is maintaining/working with one (or more) of these BSPs, please let me know if you're able to test the separate legacy-net repository and if you have any feedback. If you're planning to test it, please add your comments here so that we know someone is going to do it and wait for your feedback. The changes will not be pushed right away and we'll wait for some feedback.

What's next?

The legacy networking repository will stay at git.rtems.org for any projects that are still using it. It is recommended that the new projects use the libbsd networking stack which is more full-featured.

Thank you for your patient reading. Any suggestion is welcome and I'm more than happy to work with you to get it more thoroughly tested before getting it merged.

Best regards,
Vijay
