Send me some email on what you are doing, and what problems you are
having, and I'll try to offer advice where I can. I've been using
4.3-RENO on an RT for some time now, and have been (very slowly)
attempting a 4.4 port. (unfortunately my "real" job often takes
priorities !!!) Best advise I can offer off-hand is to look
at how the HP or Sun machine-dependent files are built up, and work
up a set from there. Some of the machine-dependent are actually
common between the machines. The ones that aren't can often
be fudged if you aren't porting the kernel. Things get more
difficult for system calls that have changed. Although traditionally
BSD adds new ones, and maintains binary compatibility for the old
ones. So you could add the code for the new system calls to the
AOS kernel, and move forward from there.
You should be able to get many portions of RENO/NET-2/4.4 running
on AOS. Regarding a newer BSD kernel, RENO still uses the traditional
BSD VM, and thus is fairly easy to port (using the AOS drivers).
But RENO was not freely available. NET-2 and 4.4 use the MACH based
VM, and would be very difficult to port unless 1) you had many hours
to learn the RT hardware and write the PMAP routines, or 2) you had
access to mach-2.5 (also not freely available), which supported the RT.
