I believe that there is a general expectation by freebsd users and developers that unsupported code should not be in CVS. Although sun4v is a very interesting platform for developers doing SMP work, I simply do not have the time or energy to maintain it. If someone else would like to step up and try his hand I would be supportive of his efforts. In the likely event that no one steps forward by the time that 7.1 is released I will ask that it be moved to the Attic.

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 and the sun4v hardware platform, who know their way around things like pmap.c and other MD places where the kernel interfaces with the "bare metal", and who are willing to make a long term (multi-year) commitment to supporting the platform.

Since there are no other current SPARC CPUs that FreeBSD can run on (the US-II has been obsolete for about 6 years and FreeBSD won't run on any more recent sun4u chips), that will also remove the justification for maintaining a SPARC64 port. I don't have the knowledge or available time to maintain the sun4v port by myself but would be happy to be part of a team doing so. One impediment I have is that I don't have a T-1 or T-2 system that I can dedicate to FreeBSD. I could work on FreeBSD in a guest domain - but since FreeBSD doesn't support either the virtual disk or virtual network, actually getting FreeBSD running there presents somewhat of a challenge. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --2YJj5f1P6Th4nBRw Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkiuo/0ACgkQ/opHv/APuIdIQwCaAgOo6jkMtJjWZq6IblsdfjZJ v7cAnRilBTMhsEbCcqlHiGWbGMY9DFQX =6heT -----END PGP SIGNATURE----- --2YJj5f1P6Th4nBRw-- From owner-freebsd-sun4v@FreeBSD.ORG Fri Aug 22 20:04:17 2008 Return-Path: Delivered-To: freebsd-sun4v@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id B57651065674; Fri, 22 Aug 2008 20:04:17 +0000 (UTC) (envelope-from ltning@anduin.net) Received: from mail.anduin.net (mail.anduin.net [213.225.74.249]) by mx1.freebsd.org (Postfix) with ESMTP id 713CB8FC23; Fri, 22 Aug 2008 20:04:17 +0000 (UTC) (envelope-from ltning@anduin.net) Received: from [212.62.248.147] (helo=[192.168.2.139]) by mail.anduin.net with esmtpsa (TLSv1:AES128-SHA:128) (Exim 4.69 (FreeBSD)) (envelope-from ) id 1KWcBb-000CuH-KI; Fri, 22 Aug 2008 21:20:39 +0200 References: <136a340a0808220719t3a170786s7fd4bcb662d0b981@mail.gmail.com> <48AED560.8010001@FreeBSD.org> <48AEEE3C.7030006@FreeBSD.org> <48AEEFFA.5030804@FreeBSD.org> <48AEF211.4060801@FreeBSD.org> <136a340a0808221121k1715b351sdfdc149128aeca8d@mail.gmail.com> Message-Id: <860DBB8A-DDA1-4AD9-9097-BB2D215DF786@anduin.net> From: =?EUC-KR?Q?Eirik_=A8=AAverby?= To: Nikolay Kalev In-Reply-To: <136a340a0808221121k1715b351sdfdc149128aeca8d@mail.gmail.com> Content-Type: text/plain; charset=us-ascii; format=flowed; delsp=yes Content-Transfer-Encoding: 7bit X-Mailer: iPhone Mail (5B108) Mime-Version: 1.0 (iPhone Mail 5B108) Date: Fri, 22 Aug 2008 21:23:31 +0200 Cc: "kmacy@freebsd.org" , "freebsd-sun4v@freebsd.org" , Pietro Cerutti Subject: Re: sun4v arch X-BeenThere: freebsd-sun4v@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Porting FreeBSD to the sun4v List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 22 Aug 2008 20:04:17 -0000 I have three t1000s, and could dedicate one to this effort.

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?

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. --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --WoqaC9TUMqqIOlla Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkivQ84ACgkQ/opHv/APuIdZuwCglKH8AiGskbfJXqdbFd9PVipt OeMAnA4v40rQalNO/rEi9s5fDfq/+9IQ =CDvj -----END PGP SIGNATURE----- --WoqaC9TUMqqIOlla--
