Hi all, We are facing the need to port FreeBSD to some (exotic) HW platform. I am totally new to this business, so I need to do some homework before coming up with a sensible project plan. The target HW platform already has some sort of a primitive proprietary hard real time OS running on it. Current plan is to have FreeBSD running in the idle process of that OS. The question is: what would be the requirements to that underlying OS from FreeBSD? What services/APIs shall it provide for FreeBSD? How the HW virtualization works in this case (RTC, etc)? If someone could point me to some resources/discussions on this subject, that would be most appreciated. Thank you! Alexander Bezprozvanny P.S. I have posted this to freebsd-platforms, but that mailing list seems to be pretty dead: for the last 12 months only spam bots and yours sincerely were posting there :-) so I decided to crosspost it to this list.
