Multiple Test Environments
by David Denny 21 Sep '03

21 Sep '03

Hello L4 There seemed to be a sentiment that your group might appreciate having the Fiasco installation process tested under a variety of Linux distributions. I've had to swap the machine I'd originally acquired for this project, because of video issues with Fiasco (onboard card, Compaq mobo, say no more), so I have a bit more disk space and with careful use of the server I can probably compile/install for between 4 and 6 distributions. Those I have in mind are Debian (as a basic sync point with yourselves). SuSE as an RPM distro, Slackware because it's different, and the two DIY distros LFS and Gentoo. What I envisage is coming back to yourselves _only_ if I have Debian issues, and for the other distros I'm happy to hack my way through and send you back the completed "Expedition Log" for each of them. That is, if you'd like to have something as a resource for other external users to use. I would not expect to ask for help outside Debian. My time is limited so I would tend to go for a major hacking event, from time to time, rather than keeping up with things as they happen At The Centre as it were. I run other free *nixes but my feeling is that at present, as an evaluation envelope, Linux is sufficient for your needs. Looking forward to this, rather

Hi, thanks,now I am using i386-elf-gcc,but also has some error. would you please give a advise which compiler and which enviroment could compile them pass? i am using fiasco-1.0.tar.gz and fiasco-1.0-oskit.tar.gz BRS john -----Original Message----- From: Volkmar Uhlig [mailto:volkmar@ira.uka.de] Sent: Wednesday, September 10, 2003 11:59 AM To: Wen, Jun (? ?

When entering the kernel debugger, you should get a line similar to this: ---------------------------------------------------ESP:201807a8 EIP:00006526 (6.00) jdb: 6.00 in this case is the thread that was active, when the debugger was entered (thread 0 of task 6). When the "fix your bindings" message appears, then note the task number (number before the dot). Compare it to the task numbers that "rmgr" or "loader" report when starting tasks, i.e. RMGR: loading "pingpong-ux" from 01d37000-01d6f72d to [ 00800000-0080f1c3 00810000-00960580 ] task #0x06 at entry 00800000 via trampoline page code 00070150 ^^^^^^^^^^ Task 6 is pingpong-ux or loader | vmlinuz.l4env,#f: Continue at l4env_init (00013350, libloader.s.so) ^^^^^^^^^^^^^^^^ Task 0x0f is L4Linux And voila, you'll find the offending program that needs fixing.

A simple "cvs update -dP" in any of your checked out directories will bring it up-to-date. Of course you still need to recompile the relevant packages afterwards. -Udo.
