Last discussion was in Aug 2008 - see http://lists.freebsd.org/pipermail/freebsd-sun4v/2008-August/000035.html At the time, I expressed an interest in working on it but that necessitated getting sun4v working as a LDom guest and I found that task was too big for the time I could allocate to it. >As I'm working on on largeSMP support, I was wondering how much sense >makes to fixing sun4v for this. I guess it's a very good choice if you want lots of virtual CPUs in a single small box but I'm not sure there's the critical mass to get the existing code into a functional state. >So what are objections (if any) about dropping sun4v? I'd be sorry to see it go but unless there's someone with the time and motivation to lead a sub-project to get it back into a working state, I don't see much point in keeping it around. --=20 Peter Jeremy --H8ygTp4AXg6deix2 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (FreeBSD) iEYEARECAAYFAk3JsGEACgkQ/opHv/APuIdLvgCfaLq6OexV6vGIL4y7grPCXllY jmoAni+yl7MpRMNoI+NrrPYxk/aOjpL+ =MoG4 -----END PGP SIGNATURE----- --H8ygTp4AXg6deix2--
