<div dir="ltr"><div>Hi</div><div><br></div><div>Heinz posted about the Beatnik BSP and I started to include this in the</div><div>response but thought it should be its own thread in the hope it would get</div><div>the attention it really needs.</div><div><br></div><div>There is a table in Chris and my EPICS meeting presentation that lists</div><div>the boards we think the EPICS community is using, the NICS they have, </div><div>and our current thoughts on the path to libbsd support. This is the link:</div><div><br><a href="https://indico.fhi-berlin.mpg.de/event/52/contributions/580/">https://indico.fhi-berlin.mpg.de/event/52/contributions/580/</a></div><div><br></div><div>Unfortunately, the site is down today. I hope that's not a permanent down </div><div>since the presentations were hosted there. But it may be OK, since below</div><div>I try to put forward what was in my head putting together slides 21 and 21</div><div>of the presentation. </div><div><br></div><div><div>Chris and I hoped these two slides would spark a discussion</div><div>which would lead to the RTEMS community knowing what boards</div><div>the EPICS community wants to be supported. And defining a path</div><div>forward so they are.</div></div><div><br></div><div>This is the text from slide 21 outlining the EPICS BSP Network Roadmap </div><div>that Chris and I identified:<br><br>+ Legacy Network Stack (e.g. libnetworking) will be obsoleted and removed<br> - Will be placed in “purgatory” repo in case someone needs it and supports </div><div> adding build system<br> - No feature upgrades and limited support even if made to build again<br>+ Libbsd stack is more full-featured and has larger size<br>+ Impacts BSPs which do not yet have LibBSD drivers<br>+ Analysis required per BSP and NIC to determine solution path<br> - In libbsd, current FreeBSD, or *BSD -- easier<br>
-
Older NICs can possibly be resurrected from old *BSD<br>
-
Custom drivers require conversion<br>
-
Freeze on RTEMS 5.x and plan to eliminate hardware<br></div><div><br></div><div>This means that the legacy stack will never go beyond NFSv2, have </div><div>IPSEC, IPV6, etc. If someone cares, it may be buildable and usable</div><div>but in another repository.</div><div><br></div><div>The next slide has this table (hope it looks OK cut and pasted):</div><div><br></div><div><span
