It's really very simple: If somebody in the project loves the ${arch} platform, it will be kept up to date and survive, if nobody does it will wither and die.

I volunteered to remove it from the tree some time back knowing that I wouldn't have the time to work on it and that no one else had the inclination to pick it up. Keep in mind that removing it doesn't bar someone from bringing back support at some time in the future, it just removes the misconception that it is in some way supported.

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-- From owner-freebsd-sun4v@FreeBSD.ORG Tue May 10 22:31:44 2011 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 B9FC71065688; Tue, 10 May 2011 22:31:44 +0000 (UTC) (envelope-from marius@alchemy.franken.de) Received: from alchemy.franken.de (alchemy.franken.de [194.94.249.214]) by mx1.freebsd.org (Postfix) with ESMTP id 4BC3C8FC08; Tue, 10 May 2011 22:31:43 +0000 (UTC) Received: from alchemy.franken.de (localhost [127.0.0.1]) by alchemy.franken.de (8.14.4/8.14.4/ALCHEMY.FRANKEN.DE) with ESMTP id p4AMLPSK035707; Wed, 11 May 2011 00:21:25 +0200 (CEST) (envelope-from marius@alchemy.franken.de) Received: (from marius@localhost) by alchemy.franken.de (8.14.4/8.14.4/Submit) id p4AMLPqn035706; Wed, 11 May 2011 00:21:25 +0200 (CEST) (envelope-from marius) Date: Wed, 11 May 2011 00:21:24 +0200 From: Marius Strobl To: Attilio Rao Message-ID: <20110510222124.GA35687@alchemy.franken.de> References: Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline In-Reply-To: User-Agent: Mutt/1.4.2.3i Cc: freebsd-sun4v@freebsd.org, freebsd-arch@freebsd.org Subject: Re: Dropping sun4v as a platform 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: Tue, 10 May 2011 22:31:44 -0000 On Tue, May 10, 2011 at 11:35:21AM -0400, Attilio Rao wrote: > I tried to look to a previous discussion on this and I failed to > locate one, thus let me raise the point here. > > As I'm working on on largeSMP support, I was wondering how much sense > makes to fixing sun4v for this. > Besides having 'tinderbox/universe' working, not so much it seems. > The code is pretty much rotting and marius@ said explicitely that an > effective effort on that platform should probabilly be more similar to > what OpenBSD does with it. Actually I just said that there should be a combined sun4u+sun4v codebase like both Linux and OpenBSD have in order to reduce duplicated code and to ease maintenance. I didn't imply one of them has superior support for sun4v that we could lift or some such. > He also is in favor of dropping the support > entirely, right now. No, I just said I'm not against dropping it, nothing more. Marius
