Much of what is ifdef'ed under "hp300" or labeled as "hp300 code" is really generic 68k stuff (sorry about that!) The pmap module and assorted VM related goo should work on a 68030 and, in theory, it would work on a 68020/68551 combo (though it was never tested). 4.4alpha also has support for the 68040. The pmap code was oriented toward the lowest-common-denominator HP MMU which means that many features of the 030/040 MMU are not used. Of course, this is the easy part, doing device drivers is where you are going to spend most of your time... >In fact if I had an hp300, I could just about open the can, heat and eat. >I get the impression the guys at Berkeley actually had hp300's on their >desks, but I could just be starting a rumor. > 68040 based hp300s are currently the main development machines at CSRG.
