Building and Using the Fiasco µ-Kernel, new user
by Julian Grizzard 25 Oct '04

25 Oct '04

Hi all, I am just starting to look into the Fiasco microkernel for some research I am doing. This looks like a very neat project and you guys have done some great work! I have followed the build instructions located at: http://os.inf.tu-dresden.de/fiasco/use.html as a starting point and wanted to share the two problems I ran into. First, I could not get the "make config" to work on my gentoo system (gcc 3.3.4, make 3.80). This is what happened: $ make config make -C ./tool/config make: *** C-Compiler needs target arch. Maybe you mean HOST_CC. Stop. $ Not sure what the problem is. I noticed the message appears to be the contents of the ${CC_} variable in l4/mk/Makeconf. My work around was to compile on a redhat 8.0 box. Second, I had this problem when I booted the system: --init--------------------------------------EIP: f0010a0f jdb: Here is the grub configuration I used on the floppy (from http://os.inf.tu-dresden.de/fiasco/use.html) # this is /floppy/boot/grub/menu.lst title hello world kernel (fd0)/rmgr -sigma0 module (fd0)/main -nokdb module (fd0)/sigma0 module (fd0)/hello After digging around, I decided to change the thid line from "module (fd0)/main -nokdb" to "module (fd0)/main -nokdb -nowait". Is this correct? It seems to be working. Thanks! -Julian

Problem building L4Linux
by Tiago Jorge 22 Oct '04

22 Oct '04

Like i said in previous emails, im trying to boot the Fedora Core 1 that i have in my disk with the L4 u-kernel. I've done a classic config stuff... i went to get the Fedora kernel config file and put it like.config in L4Linux kernel directory. I've configured the l4 options i tried to built it. I'm trying to build the 2.4.22 L4Linux kernel. The error that gave me it's here... -D__KERNEL__ -I/root/l4linux-2.4/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -g -DLINUX_ON_L4 -pipe -mpreferred-stack-boundary=2 -march=i686 -nostdinc -iwithprefix include -DKBUILD_BASENAME=apm -c -o apm.o apm.c apm.c: In function `apm_bios_call': apm.c:626: warning: implicit declaration of function `loadsegment' apm.c:626: error: `fs' undeclared (first use in this function) apm.c:626: error: (Each undeclared identifier is reported only once apm.c:626: error: for each function it appears in.) apm.c:626: error: `gs' undeclared (first use in this function) apm.c: In function `apm_bios_call_simple': apm.c:679: error: `fs' undeclared (first use in this function) apm.c:679: error: `gs' undeclared (first use in this function) apm.c: In function `apm_init': apm.c:1984: warning: implicit declaration of function `set_base' apm.c:1984: error: `gdt' undeclared (first use in this function) apm.c:1986: warning: implicit declaration of function `_set_limit' make[1]: *** [apm.o] Error 1 make[1]: Leaving directory `/root/l4linux-2.4/arch/l4/kernel' make: *** [_dir_arch/l4/kernel] Error 2 Could somebody help me Thaks in advance Tiago

I must pass to the kernel an init, but i can't use the initrd command from GRUB, but i found out that initrd can be passed to the kernel as an argument. >/> is this the right way to do it?

The file name doesn't sound likes it's a rd. this file is a initrd file to the L4Linux kernel. What i'm trying to do is boot the Fedora that i have in the disk using the new kernel. But i think i have overcome the L4 problems. Now is just plain Linux Kernel problems (i think)... but tks for the help anyway. cheers Tiago <http://os.inf.tu-dresden.de/%7Eadam/>

Problem booting L4Linux 2.4 + L4Env (Part 3)
by Tiago Jorge 21 Oct '04

21 Oct '04

ok... i think this is my last email today for this to work... :) I can now boot L4Linux with the drops RAMdisk and everything goes all right in VMware and in real hardware. But now i have a few more questions: 1. I'm trying to boot the Fedora Core 1 that i have in my disk with L4Linux kernel but i haven't found a way yet. Like we say here in portugal, i've been trying to "hammer" a solution, but didn't worked out. my grub.conf looks like this: title Fiasco + L4Linux root (hd0,0) kernel /fiasco/rmgr -sigma0 task modname "vmlinuz" module modaddr 0x02000000 module /fiasco/main -nokdb -nowait -serial_esc -comspeed 115200 -comport 1 module /fiasco/sigma0 module /fiasco/vmlinuz no-scroll no-hlt l4irqack=linux root=/dev/hda5 module /fiasco/2.2.27.img <===== i'm doing this beacause i can't use initrd is this the right way to do it? Im i missing something? he says that can't find a init and even when sometimes he loads the img, it crashes while loading it from disk. /dev/hda5 is my / partition. 2. Is it mandatory in L4Env boot to have the tftp server? can't i boot it from disk? Ok... i'm beeing very annoying for today, but i'll write a tutorial in the end :))) Thaks in advance Tiago

Problem booting L4Linux 2.4 + L4Env (Part 2)
by Tiago Jorge 21 Oct '04

21 Oct '04

hello to you all. I've sent my first email yesterday but i havent introduced myself. I'm Tiago Jorge, from the Faculty of Sciences of the University of Lisbon, and i'm doing my final work (Building a TCB using a u-kernel, in this case L4 plus all the additions that you and others have made for it). So, i wiil be "bugging" you for a short while from know :). Yesterday, i couldn't boot "names" server. Today i've have acheived that goal. I thank here all the fast aswers that people gave to me :). Today i've encountered another problem. This problem happens with the L4Linux kernel (i think!!), using it with his plain version and with his L4Env version, but i will focus on the L4Env version.

grub-0.95
by Rudolf Weber 11 Oct '04

11 Oct '04

Hallo, I adaped the patch for grup for grub-0.95. The grub in the Dresden CVS don't compile with gcc-3.3. and gcc-3.4.0 (as I tried it) Grub2 is very promissing, but it don't find the symbol tyble (as I tried it) I think it is a good idea to put the Dresdner grub enhancement in the official grub2. Greetings Rudolf Weber P.S: My new Notebook boots now from the net and the grub have now variables ... P.P.S: I have worked on RACE http://www.infnet.verein.de/produkte/race/ and dream to map ACE/RACE on L4 -- -- --------------------------------------------------------------- Rudolf Weber http://www.infnet.verein.de/~rw E-Mail: rfweber(a)tesionmail.de
