I dont know :) Hm... These points all belong to the big topic, getting modern linux distro binaries (NTPL stuff) to work. This would be a good thing because I'm stuck on some old debian sarge that was just moved to the archives. Step one would be to get the simple single-threaded stuff to run like echo and cat. The part point here is TLS. I had a somewhat working plan9 driver for it but never packaged it up because i wanted the whole thing working before submitting a kernel patch. You may later progress to multithreaded apps wich use futex syscall. The way I work on linuxemu is randomly trying stuff out, see where it crashes... try to understand why it crashes... implement/fix syscalls and try again. Sometimes it easy and sometimes you scratch your head for a several months. Its hard to estimate the time needed to get X running because you never know what crazy optimization shit the linux/libc guys come up with next to make you suffer. Here is always a huge risk of failure in linuxemu because all the details are in Ulrich Dreppers head only or encrypted with c-preprocessor-ifdef-encryption in the glibc-code so getting help is very hard and most of the stuff you have to find out yourself (this may cause brain damage over time). I cant (officialy) mentor you as I'm short of time and have no scientific background or something, but I will try to give you all infeormation/code and support I have... Its good to hear that someone starts taking over some work! :) Just drop me an email. I may be in irc from time to time too but dont count on it. -- cinap --upas-jtxruxtzsnqacizeuufctgbpnw Content-Type: message/rfc822 Content-Disposition: inline Return-Path: <9fans-bounces+cinap_lenrek=gmx.de@9fans.net> X-Flags: 0000 Delivered-To: GMX delivery to cinap_lenrek@gmx.de Received: (qmail invoked by alias); 25 Mar 2009 13:58:35 -0000 Received: from gouda.swtch.com (EHLO gouda.swtch.com) [67.207.142.3] by mx0.gmx.net (mx078) with SMTP; 25 Mar 2009 14:58:35 +0100 Received: from localhost ([127.0.0.1] helo=gouda.swtch.com) by gouda.swtch.com with esmtp (Exim 4.67) (envelope-from <9fans-bounces@9fans.net>) id 1LmTYx-0001RR-U9; Wed, 25 Mar 2009 13:54:35 +0000 Received: from m13-70.163.com ([220.181.13.70]) by gouda.swtch.com with smtp (Exim 4.67) (envelope-from ) id 1LmTYv-0001RM-8L for 9fans@9fans.net; Wed, 25 Mar 2009 13:54:33 +0000 Received: from upczhsh ( [124.16.139.196] ) by ajax-webmail-wmsvr70 (Coremail) ; Wed, 25 Mar 2009 21:54:23 +0800 (CST) Date: Wed, 25 Mar 2009 21:54:23 +0800 (CST) From: "Zhao Shuai" To: 9fans@9fans.net Message-ID: <29998388.496361237989263735.JavaMail.coremail@bj163app70.163.com> MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_Part_133473_5160626.1237989263734" X-Originating-IP: [124.16.139.196] X-Priority: 3 X-Mailer: Coremail Webmail Server Version XT2_snapshot build 090319(6914.2271.2266) Copyright (c) 2002-2009 www.mailtech.cn 163com X-CM-TRANSID: RsGowLCr8gqPN8pJmeO2AA--.35683W X-CM-SenderInfo: hxsf6xlvk6il2tof0z/1tbitgUwDEPUjH8k3QAAsS X-Coremail-Antispam: 1U50xBIdaVrnRJUUUcCb7IF0VCF04k20xv_GFyrM7k042IE42 xK82IY64kIx2x0424lb7IF0VCFI7km07C26c804VAKzcIF0wAqjxCE34x0Y48IcwAC67AE wI8IwI0EV3sKBsskM4IEnf9ElVAFpTB2q-sK649IAas0WaI_GwCS07vEb7Iv0xC_Jr1lV2 xY67kC6x804xWlV2xY67C26xCjj4IEw4AK0wCS07vE1I0EscIYIxCEI4klw4CSwwCS07vE 5I8CrVAqjxCE14ACF2xKxwCS07vE5I8CrVACY4xI64kE6c02F40Ex7xfMIAIbVAv7VCjz4 8v1sIEY20_JwCS07vE7480Y4vEI4kI2Ix0rVAqx4xJMIAIbVCF72vE77IF4wCS07vEx4CE 17CEb7AF67AKxVWUJVWUXbIYCTnIWIevJa73U Subject: [9fans] gsoc linuxemu project help X-BeenThere: 9fans@9fans.net X-Mailman-Version: 2.1.9 Precedence: list Reply-To: Fans of the OS Plan 9 from Bell Labs <9fans@9fans.net> List-Id: Fans of the OS Plan 9 from Bell Labs <9fans.9fans.net> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: 9fans-bounces@9fans.net Errors-To: 9fans-bounces+cinap_lenrek=gmx.de@9fans.net X-GMX-Antivirus: 0 (no virus found) X-GMX-Antispam: 0 (Mail was not recognized as spam) X-GMX-UID: vgH5cZEYMmApOpQryGFn/EIxMjQ1N13H ------=_Part_133473_5160626.1237989263734 Content-Type: text/plain; charset=gbk Content-Transfer-Encoding: 7bit Hi all, I am interested in the GSoc project: Linuxemu improvement.
