That's my understanding also. I don't think anyone currently looks at
the PIC/VMEbus support in libbsd. This would seem to be the next high
priority, as we look to make our legacy libnetworking stack obsolete
soon. (More on that, coming soon.) Do you/anyone have any idea what
the PIC/VMEbus support might entail? (Has anyone tried scoping it
out.)
Does anyone know the state of VMEbus on Qemu? Generally, VMEbus
hardware is out of budget for my University team and for RTEMS Project
resources, so we would need either sponsorship/donations to contribute
in that direction unless qemu is mature enough.
