--liOOAslEiF7prFVr Content-Type: text/plain; charset=us-ascii Hi all, The attached thread (apologies for the volume of text, but it is all relevant) came up on freebsd-xircom last week. Jose Alcaide actually posted to -mobile on the same subject a week or so before, but got no response. We figure it's definitely nothing to do with the Xircom driver in particular and probably nothing to do with pccard, so I'm bouncing it to any interested kernel gurus. Essentially, the irq line to which clk0 interrupts are accounted (in the output from vmstat -i) changes when pccards are inserted/removed. The same effect has been seen with cards using the xe0 and ed0 drivers. Any ideas?

It works fine, but I found something very strange. After booting the system (with no pccard inserted), "vmstat -i" shows: interrupt total rate clk0 irq0 718701 100 ... But, just after I insert the Xircom card and it is detected and enabled, another "vmstat -i" shows: interrupt total rate clk0 irq3 732248 110 (IRQ3 is the first available interrupt in my system, and it is assigned to the Xircom card by the pccardd daemon. I am running FreeBSD 3.4-RELEASE, no PAO.) After inserting the card, the clk0 interrupts are accounted to the interrupt level used by the Xircom card (I have tried other IRQ levels with the same result). The 100 interrupts/second generated by the timer are added to the interrupts generated by the Ethernet adapter. Since I don't have any other PCMCIA cards, I don't know whether this "problem" only happens with the xe driver or, on the contrary, it is a general problem of the FreeBSD's pccard driver. Did anybody find this same behavior? -- JMA ----------------------------------------------------------------------- José Mª Alcaide | mailto:jose@we.lc.ehu.es Universidad del País Vasco | mailto:jmas@FreeBSD.org Dpto. de Electricidad y Electrónica | http://www.we.lc.ehu.es/~jose Facultad de Ciencias - Campus de Lejona | Tel.: +34-946012479 48940 Lejona (Vizcaya) - SPAIN | Fax: +34-946013071 ----------------------------------------------------------------------- "Beware of Programmers who carry screwdrivers" -- Leonard Brandwein --liOOAslEiF7prFVr Content-Type: message/rfc822 Return-Path: <owner-freebsd-xircom@lovett.com> Received: from valis.goatsucker.org (valis.goatsucker.org [192.168.1.1]) by lungfish.freeserve.co.uk (8.8.8/8.8.8) with ESMTP id VAA01629 for <scott@valis.goatsucker.org>; Tue, 25 Jan 2000 21:13:37 GMT (envelope-from owner-freebsd-xircom@lovett.com) X-From_: owner-freebsd-xircom@lovett.com Tue Jan 25 16:36:46 2000 Envelope-to: scott@lungfish.freeserve.co.uk Delivery-date: Tue, 25 Jan 2000 16:36:46 +0000 Received: from pop.pol.net.uk by valis.goatsucker.org (fetchmail-4.3.8 POP3) for <scott/valis.goatsucker.org> (multi-drop); Tue, 25 Jan 2000 21:13:37 GMT Received: from [130.88.200.93] (helo=serenity.mcc.ac.uk) by mail7.svr.pol.co.uk with esmtp (Exim 3.13 #0) id 12D8xR-0005Vn-00 for scott@lungfish.freeserve.co.uk; Tue, 25 Jan 2000 16:36:45 +0000 Received: from dogma.freebsd-uk.eu.org ([130.88.200.97]) by serenity.mcc.ac.uk with esmtp (Exim 1.92 #3) for scott@lungfish.freeserve.co.uk id 12D8xQ-0006SD-00; Tue, 25 Jan 2000 16:36:45 +0000 Received: from serenity.mcc.ac.uk (serenity.mcc.ac.uk [130.88.200.93]) by dogma.freebsd-uk.eu.org (8.9.3/8.9.3) with ESMTP id QAA12726 for <scott@freebsd-uk.eu.org>; Tue, 25 Jan 2000 16:36:44 GMT (envelope-from owner-freebsd-xircom@lovett.com) Received: from [212.74.0.25] (helo=florence.pavilion.net) by serenity.mcc.ac.uk with esmtp (Exim 1.92 #3) for scott@freebsd-uk.eu.org id 12D8xP-0006S2-00; Tue, 25 Jan 2000 16:36:43 +0000 Received: from gallia.lovett.com (gallia.lovett.com [207.126.105.195]) by florence.pavilion.net (8.9.3/8.8.8) with ESMTP id QAA04592 for <scott@uk.freebsd.org>; Tue, 25 Jan 2000 16:33:23 GMT (envelope-from owner-freebsd-xircom@lovett.com) Received: from majordom by gallia.lovett.com with local (Exim 3.12 #1) id 12D8tx-000EWl-00 for freebsd-xircom-outgoing@lovett.com; Tue, 25 Jan 2000 08:33:09 -0800 Received: from [194.178.168.50] (helo=smtppzh.pzh.nl) by gallia.lovett.com with smtp (Exim 3.12 #1) id 12D8tv-000EWf-00 for freebsd-xircom@lovett.com; Tue, 25 Jan 2000 08:33:08 -0800 Received: FROM smtp.pzh.nl BY smtppzh.pzh.nl ; Tue Jan 25 17:31:37 2000 0000 Received: from PZH40-1-Message_Server by smtp.pzh.nl with Novell_GroupWise; Tue, 25 Jan 2000 17:31:42 +0100 Message-Id: <s88dddfe.017@smtp.pzh.nl> X-Mailer: Novell GroupWise 5.5.2 Date: Tue, 25 Jan 2000 17:31:08 +0100 From: "ROGIER MULHUIJZEN" <MULHUIJZEN@PZH.NL> To: <freebsd-xircom@lovett.com>, <jose@we.lc.ehu.es> Subject: Re: clk0 interrupts accounted to xe ???

(The ping -f generated a few interrupt-level buffer overflows) I think we can safely say that this is either something in vmstat, or in pccardd. Warner, what's your take on this?

Warner, what's your take on this? > I absolutely agree. The problem is not in the xe driver. I have carefully examined the vmstat and pccard sources. Vmstat is innocent; it simply uses kvm_read(), so the interrupt accounting is messed up in the kernel memory. Pccardd has nothing to do with interrupt registration; this support is in the pccard driver. And with respect to pccard, the calls to register_intr() appear to be OK. Really, I have no idea of where is the problem. We need a kernel guru :-) This thread should be moved to -mobile, I think. -- JMA ----------------------------------------------------------------------- José Mª Alcaide | mailto:jose@we.lc.ehu.es Universidad del País Vasco | mailto:jmas@FreeBSD.org Dpto. de Electricidad y Electrónica | http://www.we.lc.ehu.es/~jose Facultad de Ciencias - Campus de Lejona | Tel.: +34-946012479 48940 Lejona (Vizcaya) - SPAIN | Fax: +34-946013071 ----------------------------------------------------------------------- "Beware of Programmers who carry screwdrivers" -- Leonard Brandwein --liOOAslEiF7prFVr-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
