I am very interested in our idle load characteristics. It seems most systems I've analyzed have an average idle interrupt rate of about 225 per second, dominated by the clk and rtc interrupts as shown below. clk irq0 99/sec rtc irq8 127/sec Since these are both clocks, I assume the arrival of their interrupts are equally spaced and not correlated to each other. How much latency do the handlers for these have? Are there any system processes which generate repetitive bursts of very short tasks? If so, how long do those tasks take? The reason why I ask is I'm coming up with a default policy for CPU sleep states which can have as high a latency as a few hundred microseconds. On an idle system, this should be fine although it does add to the latency for the above clock handlers. But I also need to be able to demote quickly to short sleep states (e.g., HLT) if the system is becoming active to decrease response times.

I can no longer ping anything on the local network, my default route drops out (which is probably dhclient's doing). Perhaps it is ARP that is broken, it's hard to tell. All I know is that I need to reboot to make it work again. Is anyone else experiencing this kind of problem?

Do you have dummynet included in the kernel ? That has been broken for me since sam's latest commit as a backout of ip_dummynet.c fixes the problem for me... -Søren From owner-freebsd-current@FreeBSD.ORG Sun Oct 12 06:23:57 2003 Return-Path: Delivered-To: freebsd-current@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 1428516A4BF for ; Sun, 12 Oct 2003 06:23:57 -0700 (PDT) Received: from srv1.cosmo-project.de (srv1.cosmo-project.de [213.83.6.106]) by mx1.FreeBSD.org (Postfix) with ESMTP id 7AE1543FAF for ; Sun, 12 Oct 2003 06:23:55 -0700 (PDT) (envelope-from ticso@cicely12.cicely.de) Received: from cicely5.cicely.de (cicely5.cicely.de [IPv6:3ffe:400:8d0:301:200:92ff:fe9b:20e7]) (authenticated bits=0) h9CDNlt2058649 (version=TLSv1/SSLv3 cipher=EDH-RSA-DES-CBC3-SHA bits=168 verify=OK) for ; Sun, 12 Oct 2003 15:23:51 +0200 (CEST) (envelope-from ticso@cicely12.cicely.de) Received: from cicely12.cicely.de (cicely12.cicely.de [IPv6:3ffe:400:8d0:301::12]) by cicely5.cicely.de (8.12.10/8.12.10) with ESMTP id h9CDNkS8089320 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NO) for ; Sun, 12 Oct 2003 15:23:47 +0200 (CEST) (envelope-from ticso@cicely12.cicely.de) Received: from cicely12.cicely.de (localhost [127.0.0.1]) by cicely12.cicely.de (8.12.10/8.12.10) with ESMTP id h9CDNk2u057150 for ; Sun, 12 Oct 2003 15:23:46 +0200 (CEST) (envelope-from ticso@cicely12.cicely.de) Received: (from ticso@localhost) by cicely12.cicely.de (8.12.10/8.12.10/Submit) id h9CDNkee057149 for freebsd-current@freebsd.org; Sun, 12 Oct 2003 15:23:46 +0200 (CEST) (envelope-from ticso) Date: Sun, 12 Oct 2003 15:23:46 +0200 From: Bernd Walter To: freebsd-current@freebsd.org Message-ID: <20031012132344.GP13791@cicely12.cicely.de> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline X-Operating-System: FreeBSD cicely12.cicely.de 5.1-CURRENT alpha User-Agent: Mutt/1.5.4i Subject: no kernel output after update X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list Reply-To: ticso@cicely.de List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 12 Oct 2003 13:23:57 -0000 OS was -current from 8th Feb and I updated to recent one today. Now I have a new world, but forced to keep with the Feb kernel, because the new kernel gives absolutely no output. Console should be on vga. I already tried switching to a vga card and to disable int routing, because I often saw problems with this kind of configuration.
