Mark Kettenis recently wrote to the misc@ and sparc@ lists with the following good news about UltraSPARC-III, and asks everyone to see what else is at least partially working…
OpenBSD 4.0 brought support for UltraSPARC-III processors. Unfortunately that support was not complete and we had to disable the L1 data cache on the cpus. Over the last few months we made significant improvements to the code that made it possible to fully enable the UltraSPARC-III on-chip caches, which makes machines with these cpus at least twice as fast. On top of that, thanks to donated hardware, we were able to add cas(4), a driver for Sun's PCI GigaSwift/Cassini ethernet adapters, which is found onboard on many UltraSPARC-III based machines. like the Sun Fire 280R, V480 and V880. So now would be an excellent time to test OpenBSD snapshots on your favourite Sun Hardware. We're also very interested in people trying OpenBSD on machines that are still listed as unsupported on OpenBSD/sparc64 web page: http://www.openbsd.org/sparc64.html Although these machines are listed as unsupported, there actually is a chance that OpenBSD will run on them. Reading through the UltraSPARC-IV processor manual, there is no reason why our kernel would not run on that CPU. So OpenBSD might run just fine on the Sun Fire V490 and V890. The same goes for the new PCI-express base machines like Ultra 25/45 and Sun Fire V125/V215/V245/V445. And if nobody ever tries running OpenBSD on these machines, we'll never know. So if you have access to any of these machines, please try booting OpenBSD on it and send us a dmesg. Thanks, Mark
