Both sound like great projects. > > For MMU support I think a lot unmerged PowerPC code is already present, > but since I would be using BBB I would only be able to use that as a > reference. Is it feasible to start it from scratch? I don't really know about the current status. But in most cases it would be a better idea to continue the work if something exists. Otherwise it's quite likely that you'll manage to create a similar unfinished version as a result. Of course it depends a bit on what exists. > > For Wi-Fi support, I would require an RTL8188 USB dongle along with > JTAG (I have a J-link and am in the process of soldering the > headers) for debugging purposes.

Regarding the RTL8188: I think that there are quite some similar adapters that would work too. And if necessary porting another driver from FreeBSD isn't too hard. So if you have trouble finding the RTL8188 search for another USB dongle that is supported by FreeBSD and ask here on the list whether it can be used too. Regarding the hot plug: Like the ticket tells: It's not entirely clear yet. My first step would be to analyze what FreeBSD does and how it detects such events. I assume that there is some kind of mechanism to notify a userspace application of new devices. Maybe we can hook into that mechanism? In that context: Please note that the ticket #3223 is strongly connected. You can also mix some parts of the two tickets if you want.
