Additionally, as the pmap/vm changes for smp are merged in, I hope to be able to minimize the differences -- so that we minimize the complexity of support. Certainly, we don't want to clobber our single processor performance -- but yet we don't want to sacrifice any advantages of the SMP configurations. Darn'it I have yet to review the SMP code, but will probably do so tonight. At least it'll give me an idea of what is going on. I hope that most of the differences are in the interrupt/exception and initialization areas. Regarding Lite/2, I believe that DG, PHK or I will take an initial cut on it (the work is from Jeff Hsu.) The stuff has aged a bit (perhaps alot.) We'll all review/work on it, using each other as resources. I don't know, maybe, if I continue to feel well from my vacation, I can work on it a bit. I'll try to commit (wishy-washy, I know) to doing something by the end of the week (fat chance) -- those kinds of promises from me usually mean next week sometime... So much to do, and only 24 hours to do it in... John
