It's gigantic in comparison and some of the passes are a lot more computationally expensive. It's a nearly 100 meg dynamically-linked binary. > > Currently running a buildworld which appears that it will be some days > before that completes.

I don't currently test buildworld on anything older than POWER8, just because it's so much time investment to do so. > The Decrementer exception seen in December CURRENT no longer exists. > Seen here > https://beta.genunix.com/freebsd/ppc64/power_mac_quad_freebsd_13_current_17_dec_2020_fail.png Yep. That is the problem that https://cgit.freebsd.org/src/commit/sys/powerpc/aim?id=d26f2a50ff48dacd38ba358d658882d51f7bdbc4 fixes. > I want to dig into the smp issue if I can but at the moment I will await > for a full buildworld/buildkernel and then see where we are. > I believe most of the smp issue boils down to the timebase getting out of sync between processors and causing paradoxes in the scheduler. There are some algorithms there that really don't like the timebase moving backwards and it can cause stuff like scheduled timers to get lost, which manifests in processes hanging in syscalls and such. There is some background discussion in https://reviews.freebsd.org/D23376 and on the list about this. The basic solution is to rendezvous and have all processors initialize their timebase to a specific value and then wait for a broadcast from the boot processor to all enable it at the same time. Unfortunately, I have limited ability to work on this as my only SMP PowerMac is a dual G4, which works a bit differently than the G5s. Although I could certainly work on the G4 version of this problem. -- Brandon Bergren bdragon@FreeBSD.org From owner-freebsd-ppc@freebsd.org Sun Feb 14 20:43:21 2021 Return-Path: Delivered-To: freebsd-ppc@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id 4C25053B74C for ;

Dennis, Other notes about various problems and at least patches for workarounds for PowerMacs are (including usefdt oddities) in comments tied to me 3 patch sets in: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233863 Comments are both in the code in the patches and in the bugzilla entry. For the bugzilla entry only some of the comments are relevant. The overall comments sequence in the bugzilla entry shows my gradual progress and is a mess to deal with early vs. better information later and such. I once wrote the following to help with reading the bugzilla comments: QUOTE What comments to read for which attachments in 233863 ? Two of the attachments have essential information, one has extra information and dealing with it is optional for the purpose (given one part of the essential patches is used). Essential: attachments 203683 and 204369 203683: read comments=20 15,23,49 (plus read any code comments in the diff) 204369: read comments=20 7,12,13,22,23,27,30,32,51 (plus read any code comments in the diff) Note:=20 comment 23 relates to the later-below extra/optional patch as well: what part of 204369 makes the below optional. You might want to only pay attention to the above 2 attachments and their comments. Extra/optional: 204368 204368: read comments=20 19,20,23,50 (plus read any code comments in the diff) Note:=20 comment 23 has the explanation of why the attachment is extra/optional (if one part of the essential patches is used).

I'll create the symlink but you'll get an empty directory until the first build completes. Note that it may take a while before the first build is actually visible on the mirrors after completing. Some of the mirrors need a couple of days to catch up and the build is only made visible when all the mirrors have it.

The machine runs fine for a while and can even do a buildworld in silence... but sometimes, pretty much at random, decides to spin up its fans to the maximum. The machine is pretty much idle when this happens so usage doesn't explain this. I haven't correlated this fully, but when the machine does this, it seems to also become unresponsive. Moving the mouse on the console shows the pointer moving but it eventually freezes. Except... the machine responds to pings, and even to SSH. *However*, it is sluggish. SSH takes forever to respond, but eventually does. Similarly, the console eventually recovers too and allows input... until things become slow again. And while it's responding, running "top" doesn't show anything strange, not in user CPU consumption nor in sys. Interestingly, running a "sysctl -a" makes the fans quiet down, maybe for a long time, maybe for a couple of minutes only. See the diff below of "sysctl -a" from while the fans are full-speed to right after, and notice that the temperatures look just fine. Any ideas about what might be happening here?

[pmac_thermal] is not the only process/thread that can end up with a problem becoming obvious. There can be less obvious problems as well. This has been an issue for years for multi-socket PowerMacs and possibly single-socket/2-core ones as well. (I've never had access to such.) (This is not the only significant PowerMac issue around but I'll keep it simple here.) === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) From owner-freebsd-ppc@freebsd.org Wed Feb 17 11:18:39 2021 Return-Path: Delivered-To: freebsd-ppc@mailman.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.nyi.freebsd.org (Postfix) with ESMTP id D2D6053C253 for ; Wed, 17 Feb 2021 11:18:39 +0000 (UTC) (envelope-from tuexen@freebsd.org) Received: from drew.franken.de (mail-n.franken.de [193.175.24.27]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "*.franken.de", Issuer "Sectigo RSA Domain Validation Secure Server CA" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4Dgb1q2vFQz57kd for ; Wed, 17 Feb 2021 11:18:39 +0000 (UTC) (envelope-from tuexen@freebsd.org) Received: from [IPv6:2a02:8109:1140:c3d:21de:da01:2af4:972f] (unknown [IPv6:2a02:8109:1140:c3d:21de:da01:2af4:972f]) (Authenticated sender: macmic) by mail-n.franken.de (Postfix) with ESMTPSA id 8CDA27220C6CE; Wed, 17 Feb 2021 12:18:35 +0100 (CET) Content-Type: text/plain; charset=us-ascii Mime-Version: 1.0 (Mac OS X Mail 14.0 \(3654.60.0.2.21\)) Subject: Re: PowerMac G5 fans going crazy From: Michael Tuexen In-Reply-To: Date: Wed, 17 Feb 2021 12:18:31 +0100 Cc: freebsd-ppc@freebsd.org Content-Transfer-Encoding: 7bit Message-Id: <1A63CB4C-76B7-46F1-B807-816C69E156A3@freebsd.org> References: To: Julio Merino X-Mailer: Apple Mail (2.3654.60.0.2.21) X-Spam-Status: No, score=-2.9 required=5.0 tests=ALL_TRUSTED,BAYES_00 autolearn=disabled version=3.4.1 X-Spam-Checker-Version: SpamAssassin 3.4.1 (2015-04-28) on mail-n.franken.de X-Rspamd-Queue-Id: 4Dgb1q2vFQz57kd X-Spamd-Bar: / Authentication-Results: mx1.freebsd.org; none X-Spamd-Result: default: False [0.00 / 15.00]; local_wl_from(0.00)[freebsd.org]; ASN(0.00)[asn:680, ipnet:193.174.0.0/15, country:DE] X-BeenThere: freebsd-ppc@freebsd.org X-Mailman-Version: 2.1.34 Precedence: list List-Id: Porting FreeBSD to the PowerPC List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 17 Feb 2021 11:18:39 -0000 > On 17.

It is a know issue for a long time. As a workaround you can put kern.smp.disabled=1 into /boot/loader.conf. Then you only have a single CPU, but the fans don't get loud...

And the reason that disabling smp fixes the issue is that with only one cpu running, there's no way for the timebase to get out of sync because there's only one timebase running in that case, so there's nothing for it to get out of sync *with*. I've been working today on one for my G4, based on the recent Book-E changes so I can experiment with it. There will need to be several different bits written to handle turning the timebase on and off. (It's done in several different ways because it involves turning the timebase signal on and off via platform specific means so that the same value can be written to every cpu without worrying about execution timing differences, and then turning it back on after every cpu has the same value set.) The difficulty here is that it's a bit messy because it's not always actually represented in the device tree, and a lot of the G5s use platform methods, which we don't have an interpreter for, so we'll have to implement it on a device by device basis in some cases. If I can get my G4 working (should be relatively easy because it's a matter of twiddling a gpio pin), I'll go ahead and try and implement some of the other bits that are needed. -- Brandon Bergren bdragon@FreeBSD.org
