There was a flurry of embedded activity in -small a while ago. Though -small is usually pretty quiet, the embedded folks hived off a separate list, called -embedded IIRC. I's suggest checking the -small archives over the last few months to see if there's anything of interest there.

Perhaps throw in a different scheduler for good measure. Having said that, I don't think that anyone is busy doing any characterisation of worst-case path lengths and lock-holds, which is the other side of the equation. -- Andrew From owner-freebsd-realtime@FreeBSD.ORG Thu Sep 21 14:17:00 2006 Return-Path: X-Original-To: freebsd-realtime@freebsd.org Delivered-To: freebsd-realtime@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 5DBA816A412 for ; Thu, 21 Sep 2006 14:17:00 +0000 (UTC) (envelope-from dave@godseyfamily.com) Received: from godseyfamily.com (cws-web.com [204.3.218.143]) by mx1.FreeBSD.org (Postfix) with ESMTP id 389E843D5C for ; Thu, 21 Sep 2006 14:16:59 +0000 (GMT) (envelope-from dave@godseyfamily.com) Received: from godseyfamily.com (localhost [127.0.0.1]) by godseyfamily.com (8.13.6.20060614/8.13.6) with ESMTP id k8LEGbPe042798; Thu, 21 Sep 2006 08:16:37 -0600 (MDT) Received: from 134.253.26.10 (proxying for 134.253.224.165) (SquirrelMail authenticated user dave) by godseyfamily.com with HTTP; Thu, 21 Sep 2006 08:16:38 -0600 (MDT) Message-ID: <56166.134.253.26.10.1158848198.squirrel@godseyfamily.com> In-Reply-To: <20060921043423.GA83407@duncan.reilly.home> References: <58304.134.253.26.6.1154383337.squirrel@godseyfamily.com> <200609200841.k8K8faiZ003394@fire.jhs.private> <20060921043423.GA83407@duncan.reilly.home> Date: Thu, 21 Sep 2006 08:16:38 -0600 (MDT) From: "David Godsey" To: "Andrew Reilly" User-Agent: SquirrelMail/1.4.5 [CVS] MIME-Version: 1.0 Content-Type: text/plain;charset=iso-8859-1 Content-Transfer-Encoding: 8bit X-Priority: 3 (Normal) Importance: Normal X-Greylist: Sender e-mail whitelisted, not delayed by milter-greylist-1.5.6 (godseyfamily.com [127.0.0.1]); Thu, 21 Sep 2006 08:16:38 -0600 (MDT) Cc: freebsd-realtime@freebsd.org, "Julian H.

I was asking because I was reading about the 6.x kernel and how the big mother of kernel locking was removed in this kernel, so I assumed realtime FreeBSD would be ramping up. Sadly, not a lot of activity in the realtime yet. > On Wed, Sep 20, 2006 at 10:41:36AM +0200, Julian H.
