FLIPS and l4linux
by Leon 08 Sep '04

08 Sep '04

Hi all, I've got a running system and some small programs running on Fiasco with DoPE and l4linux-2.4. I want to investigate FLIPS to use as an extension to one of the programs (network capable). The difference between compiling L4 and all its packages now is that I must set the parameter LINUX24_DIR to point to a directory with vanilla kernel code (I used 2.4.27) instead of previously when the parameter pointed to the L4LINUX directory (l4linux-2.4). The last one is currently my working setup. Q1: Was I doing it wrong the whole time and was just lucky to get it working? Anyway the newly compiled FLIPS system starts to load as usual but as soon as l4linux is loaded is stops with a cursor blinking below the penguin with NO text (console) output. Here is the debug output: EXT3-fs: mounted filesystem with ordered data mode. VFS: Mounted root (ext3 filesystem) readonly. Warning: unable to open an initial console. simple_t| ERROR: task #13 doesn't match: client 11.03, owner 0.00 l4lx | l4ts_create_task(): failed (server=A.00, ret=-3, exc 0) The system is still operational and I can start my programs from the "doperun" terminal. Q2: Any suggestions on why my l4linux does not want to load anymore? Thanks Leon

New L4Env release
by Ronald Aigner 01 Sep '04

01 Sep '04

The TU Dresden OS team is happy to announce the next release of L4Env - the development environment for L4/Fiasco. Please visit the L4Env website http://os.inf.tu-dresden.de/l4env/ to download version 0.2 or browse the L4Env documentation. This new release contains our efforts to further improve L4Env, so you can look forward to enhanced functionality of, for instance, the loader or region manager, which make it easier to build applications for L4. Starting with this release we will also provide you with daily snapshots of the L4Env packages at http://os.inf.tu-dresden.de/l4env/. We would like to invite you and try L4Env 0.2 and help us improve it even more. Yours, the L4Env team.

names for the L4 ipc functions for the x86 architecture
by Rafal Somla 26 Aug '04

26 Aug '04

Hi, I tried to compile and install Fiasco-ux and L4Env. It seems that the l4sys ipc functions for the x86 architecture have additional _i386_ part in their name. E.g., l4_i386_ipc_call instead of l4_ipc_call. The result is that, for instance, I can't compile the hello server without renaming the functions. Is that intentional or did I messed up the instalation? Thanks for any help on that, Rafal

L4 based schedulers
by Aidan Delaney 25 Aug '04

25 Aug '04

Hey all (Güten tag or G'day), How many "full" operating systems use l4? I'm aware of DROPS and am wondering if there is anything else that has a "process" model and scheduler build around l4. Thank you, -- Aidan Delaney email: adelaney(a)cs.may.ie web: http://www.cs.may.ie/~adelaney gpg: http://www.cs.may.ie/~adelaney/public_key.asc

ANNOUNCE: L4Linux 2.6
by Adam Lackorzynski 20 Aug '04

20 Aug '04

We are happy to announce the release of the latest version of L4Linux based on Linux 2.6. L4Linux is a modified version of Linux running on L4. This version of L4Linux is based on L4Env and on the Fiasco microkernel. It supports the x86 architecture and is available via anonymous CVS. This release is not ready for performance assessments and still awaits improvements in some regions but is nevertheless stable enough to run most of the available Linux programs. For more information refer to the L4Linux-2.6 website: http://os.inf.tu-dresden.de/L4/LinuxOnL4/ For other available L4Linux versions start at http://l4linux.org/ Adam

Hi everybody! Is there any tool out there, with which I can read files having the extension "&l3" with windows XP? I worked with the L3 system during my schooldays and found an old disk containing ELAN-code. I desperatly need to review this code, but unfortunately I can not install L3 because I do not have the Install-disks anymore! ---------------------------------------------------------------------------------------- Hallo Zusammen! Gibt es irgendwo ein Tool, mit dem ich ".&l3"-Dateien unter windwos XP lesen kann? Während meiner Schulzeit haben wir viel mit ELAN programmiert und ich habe eine Diskette, auf der verschiedene Quellcodes aus dieser Zeit sind. Ich muß diese Codes dringend lesen! Habe aber kein L3-System mehr auf meinem Rechner. ---------------------------------------------------------------------------------------- Thanks for any help Dankbar für jeden Tipp Alexander Grotzsch ________________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!

RE: qemu and l4linux2.4
by Volkmar Uhlig 16 Jul '04

16 Jul '04

There is a bug in the current interrupt handler code. I'm not 100% sure but I think we have a patch to that. The problem is that with Pistachio we run APIC interrupt mode and when IRQs are disabled they usually get re-injected with a self-IPI (I'm not arguing about the sensibility of that strategy though). Right now L4Linux doesn't do that and the IRQ gets lost. - Volkmar > > -- > Mat/tia Belletti - Undergraduate student @ cs.unibo.it > ICQ: 33292311 - email: mbellett(a)cs.unibo.it > IRC: RedGlow - site(s): http://www.cs.unibo.it/~mbellett > Linux registered user 299762 @ Linux registered machine 213003 > > _______________________________________________ > l4-hackers mailing list > l4-hackers(a)os.inf.tu-dresden.de > http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers >

qemu and l4linux2.4
by Mattia Belletti 16 Jul '04

16 Jul '04

I tried to run an l4linux (pistachio 0.4, l4linux from daily cvs), and it all went fine until: hda: QEMU HARDDISK, ATA DISK drive hdc: QEMU CD-ROM, ATAPI CD/DVD drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: attached ide-disk driver. irq 14 not enabled irq 14 not enabled IRQ resend (14) With quite a lot of delay after each of the two 'hda: QEMU HARDDISK...' and 'hdc: QEMU CD-ROM...', and, after that, it finally stops. Qemu runs normal linux fine - any idea where to go to find the problem? -- Mat/tia Belletti - Undergraduate student @ cs.unibo.it ICQ: 33292311 - email: mbellett(a)cs.unibo.it IRC: RedGlow - site(s): http://www.cs.unibo.it/~mbellett Linux registered user 299762 @ Linux registered machine 213003
