Let NetBSD keep doing the excellent job it does do on all the different platforms it supports- including 32 bit sparc. It's also doing a good, but slow, job of getting to sparc64 (and doing it right). FreeBSD has different markets/customers, though, and the ones for Sparc don't give a hoot about 32 bit sparc. David has offered a U1 for folks wanting to work on this. Frankly, this is helpful, but a tougher call- we'd have to support SBus right away, and, frankly, I'd also like to avoid that as well- so the first model supported is likely to be U10/PCI (Simba chipset) with U30/60 being a close followon (Psycho). All of this will have to be (officially) reverse engineered from Linux && NetBSD-sparc64 implementations as the doc sets are a bit hard to find and/or sparse (especially wrt chip *and* OBP errata). -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-sparc" in the body of the message
