Just so everyone is on the same page, what is needed to keep sun4v viable are people with experience with (or intention to learn about) low level architectural and implementation details of the FreeBSD kernel
What documentation is currently accurate for this beyond the source code? The only things I can quickly find are: "Design & Implementation of FreeBSD 5.2" and "FreeBSD Architecture Handbook". The former is getting quite old and I'm not sure how up-to-date the latter is kept.
the sun4v hardware platform,
Is the documentation at http://www.opensparc.net/opensparc-t1/index.html and http://www.opensparc.net/opensparc-t2/index.html adequate for this or is there additional information that is needed? Is there any tutorial style documentation on the low-level T1/T2 details?
who know their way around things like pmap.c and other MD places where the kernel interfaces with the "bare metal",
I've poked around the low-level details of FreeBSD/i386 and /Alpha in the past, though I'm nothing like an expert at it. sun4v/sun4v is only about twice the size of a 6th Edition kernel...
and who are willing to make a long term (multi-year) commitment to supporting the platform.
Yes.
Is there a summary of the open issues somewhere? There are no sun4v PRs open. http://wiki.freebsd.org/FreeBSD/sun4v effectively hasn't been touched since November 2006 and suggests that the only critical issue is lack of serial port support.
