I'm just wondering if the Niagara chip (by Sun) is supported on

Full and proper support of the Ultrasparc III processor is pretty
much an implied requirement first... and we're still working on that...
Sorry for my ignorance but why Ultrasparc III? I taught Niagara was
based on Ultrasparc II, and there is no talk ofproblems about
UltrasparcII on http://www.openbsd.org/sparc64.html.
"The Niagara chip is comprised of eight four-threaded UltraSparc-II
cores, and running at 1.2 GHz" Taken from:
http://www.itjungle.com/breaking/bn080206-story01.html - 3rd paragraph
The issue that Mark Kettenis is working on has to do with getting the
US3 running at full speed. Currently, if you are running on a US3,
you aren't running at full speed because the cache is disabled. There
are likely fewer than 5 people on the planet running Mark's patches
and I'm one of them.
Small form-factor US3 machines (1 or 2U) are currently much more
interesting to many developers and users, both from a price and
availability standpoint. Not everyone wants to run an E450 in their
living room.
Given that Niagara is multi-core and multi-threaded and we don't have
SMP support yet for sparc64, it makes sense to solidify the current
sparc64 offering first. That, and I won't mention Theo's thoughts on
the "virtual machine of sorts" that is Niagara...
Of course, interested parties with large budgets and desire to see
this work happen are more than free to contact me to have a project
charter written and a contract signed...

I see I see, thanks for the explanation. I hope I didn't get your hopes
up for financing...I am only a poor student finishing his Bachelor's...
