Hello.
I am a university student in japan. I have a question about an error in building L4Linux 2.6.
I want to run L4Linux with L4Ka::Pistachio on an IA32 architecture machine. I got a following error when I tried to make L4Linux.
------------------------------------------------------------- ..... LD .tmp_vmlinux1 KSYM .tmp_kallsyms1.S AS .tmp_kallsyms1.o LD .tmp_vmlinux2 KSYM .tmp_kallsyms2.S AS .tmp_kallsyms2.o LD .tmp_vmlinux3 KSYM .tmp_kallsyms3.S AS .tmp_kallsyms3.o CHK include/linux/version.h *** Error: Headers not exportable for this architecture (l4) <--- this error make[1]: *** [headers_install] error 1 make: *** [vmlinux] error 2 -------------------------------------------------------------
My build way is based on the official website (http://os.inf.tu-dresden.de/L4/LinuxOnL4/build-2.6.shtml). First, I download the source of L4Linux 2.6 and the l4linux-2.6-env module using SVN repository.
[root@lin root]# svn co http://svn.tudos.org/repos/l4linux/trunk l4linux-2.6 [root@lin root]# svn co -N http://svn.tudos.org/repos/tudos/trunk tudos [root@lin tudos]# ./repomgr checkout l4linux-2.6-env
The directory structure is following.
tudos/ - build/ - dice/ - l4/ - l4linux-2.6/ - repomgr - tools
Next, I configure and make L4 enviroment.
[root@lin tudos]# make -C l4 O=/root/tudos/build/ config [root@lin tudos]# make -C l4 O=/root/tudos/build/
In DROPS Configuration Tool, I set the path to the DROPS tree. Other parameters are default.
Paths and Directories ---> DROPS_STDDIR: "/root/tudos/"
Finally, I go to the l4linux-2.6 directory and configure and make.
[root@lin l4linux-2.6]# make menuconfig [root@lin l4linux-2.6]# make
I change a lot of parameters in L4Linux kernel configuration to avoid many other errors in start and end of make sequence.
L4Linux configuration ---> - (/root/tudos/build/) L4 tree build directory Proccessor type and features ---> - [ ] Symmetric multi-proccessing support - Subarchitecture Type (PC-compatible) ---> - [ ] HPET Timer Support - Preemption Model (No Forced Preemption (Server)) ---> - [ ] Local APIC support on uniproccessors - [ ] Machine Check Exception - High Memory Support (off) ---> - [ ] MTRR (Memory Type Range Register) support - [ ] kexec system call Power Management option (APIC, APM) ---> - [ ] Power Management support Bus option (PCI, PCMCIA, EISA, MCA, ISA) ---> - [*] PCI access support PCI access mode (Direct) ---> File systems ---> - Pseudo filesystems ---> - [ ] HugeTLB file system support
The error massage may be printed by l4linux-2.6/Makefile (line 928). If there is not file "include/asm-$(ARCH)/Kbuild", it print the error in make. But I seem not to exist Kbuild in include/asm-l4 direcory ...
What is the cause of the error ? I think that some settings about L4 environment are lacked. But I cannot understand the sure way to build L4Linux and its environment yet... Please help me !
Thanks and best regards, Lin

You seem to use the Dresden version of L4Linux which AFAIK only runs on L4/Fiasco, not (yet?) on L4Ka::Pistachio.
Please try it with L4/Fiasco.
Cheers, Martin

Please disable the "Run 'make headers_check' when building vmlinux" configuration option to make to error go away.

Hi Lin,
I want to run L4Linux with L4Ka::Pistachio on an IA32 architecture machine. I got a following error when I tried to make L4Linux.
If you want Linux on top of Pistachio you should take a look at wombat, which is a paravirtualized Linux initially running on top of pistachio, you may want to check the ok-labs.com web site for this.
Cheers,
Jorge
Hi, All. Sorry for my late response.

Thank you for information, I'll try it one of these days. I will use L4/Fiasco for the time being.

Thanks, I tried to build L4Linux with L4Fiasco a short time ago. My build way is the same to Fiasco official page (http://os.inf.tu-dresden.de/fiasco/use.html). But the result was the same to before ... I'm glad if you read the following text about new errors.

I've tried to build with setting disable it before, but I got following errors.

I fixed that by now. (Update the source.)
(Without it, we cannot build L4Linux ??) If so, what is these error's cause ?
To fix that for now please just don't use modules. I fixed a couple of those above internally but I cannot fix all of them, e.g. the gameport driver looks suspicious to me.
I feel that there is the issue in my L4 environment...
Doesn't seem like that.

Hi, Adam. Thank you for your quick response !

I checked out the updated source and made sure the "header check" option is off in default. Thank you !

I tried making L4Linux with the kernel configuration which was changed into like the following, then the make sequence was completed.
Loadable module support ---> - [ ] Enable loadable module support Device Drives ---> - Input device support ---> - [ ] Joysticks ---> - Hardware I/O ports ---> - [ ] Gameport support
But the "Section mismatch" errors in "MODPOST vmlinux" remain yet.

And I'm trying to boot the made L4Linux and Fiasco with GRUB. My GRUB doesn't have "modaddr" command, so I want to use "single-image-mode" written in ML log (http://www.mail-archive.com/l4-hackers@os.inf.tu-dresden.de/msg02591.html). I'm reading "README" and "modules.list" now, but I cannot understand how to use it yet. I'll try harder...

Most of those are from Linux, don't take them too serious.

Over 100MB is too much. Can you please post your .config from the L4Linux build directory?!

'Just' warnings...

I recommend using the -modaddr switch to bootstrap which does the same as the modaddr GRUB command.

Ok, I see. I wrote "error" instead of "WARNING", but it was a mistake. Sorry...

My ".config" file may be too strange for you because I am a beginner in configuring or building kernels. I probably added many vain components to the kenel unconsciously.

Thanks, but I'd already gained the GRUB which has the "modaddr" command by using the patch (grub-0.97-os.1.diff.gz) you made. And I tried to boot L4Linux/Fiasco(+l4dope) with it, however it failed. The kernel configuration is equal to the posted file. The "menu.lst" in the "/boot/grub" directory and the loader configuration file "linux26.cfg" are as follows.

Over 100MB is too much. Can you please post your .config from the L4Linux build directory?!
My ".config" file may be too strange for you because I am a beginner in configuring or building kernels. I probably added many vain components to the kenel unconsciously.
Lots of stuff switched on (too much). Please use the attached config as a basis, this one should be much better.
And I'm trying to boot the made L4Linux and Fiasco with GRUB. My GRUB doesn't have "modaddr" command, so I want to use
I recommend using the -modaddr switch to bootstrap which does the same as the modaddr GRUB command.
Thanks, but I'd already gained the GRUB which has the "modaddr" command by using the patch (grub-0.97-os.1.diff.gz) you made. And I tried to boot L4Linux/Fiasco(+l4dope) with it, however it failed.

This message sounds harmless.
I attached the log which all of serial output are written in. I could not find any messages which is relate to this freeze. Do you have anything about it ?
The kernel command line says that the kernel output goes to the second serial interface. Obviously you won't see more Linux kernel messages in the Fiasco debug log as well as in any Dope window. Do you see something on ttyS1? If you want to see more messages in the debug log, enable the "serial driver" under "stub drivers" in L4Linux and replace the console=... option with console=ttyLv0 If you leave it out or write console=tty0 the output will go to the Dope window.

There is no message on ttyS1. I changed "console=ttyS1,1152000" to "console=ttyLv0" and enable serial console support on L4Linux configration. The result is the following (when using DOpE).

The kernel command line says that the kernel output goes to the second serial interface. Obviously you won't see more Linux kernel messages in the Fiasco debug log as well as in any Dope window. Do you see something on ttyS1? If you want to see more messages in the debug log, enable the "serial driver" under "stub drivers" in L4Linux and replace the console=... option with console=ttyLv0 If you leave it out or write console=tty0 the output will go to the Dope window.
There is no message on ttyS1. I changed "console=ttyS1,1152000" to "console=ttyLv0" and enable serial console support on L4Linux configration. The result is the following (when using DOpE).
But the DOpE window is opened? And is there something in the window? I have no clear idea right now what could be wrong. Could you post your .config, that you are using right now, again? You could also try to disable PCI just for a test and see if it gets to the point where Linux wants to mount the root partition and can't because no driver is there. Maybe making earlyprintk to earlyprintk=keep makes a difference too.

The DOpE window doesn't appear (while I use the ".config" given from you). The cause of it is not clear...
I have no clear idea right now what could be wrong. Could you post your .config, that you are using right now, again?
The attached configuration is used right now, which uses the DOpE. The kernel configuration file and the GRUB menu are the following.

I disabled PCI and retried, but the setup stops at the same line (some PCI related messages disappear). And it seem that the sequence doesn't come to the step of mounting root partition yet because the results are the same though I change the "root=..." value.

Ok, so some other thing. Can you please leave out DOpE and try without? Please add VGA and PS/2/Keyboard support to your L4Linux configuration. You can also use the x86-native_defconfig configuration to achieve the same. Hopefully the behaviour will be different with such a setup. If it still hangs I would like to see a Alt-Print-p and Alt-Print-t (SysRQs...).
I see nothing obvious wrong in your attached .config.

Thanks for your checking .config. I quitted using DOpE, and enabled VGA and keyboard like the following.
###### L4Linux Kernel Configuration ######
o Device Drivers ---> o Input device support ---> o [*] Keyboards ---> o --- Keyboards o <*> AT keyboard o Graphics support ---> o <*> Support for frame buffer devices o <*> VGA 16-color graphics support o [*] VESA VGA graphics support o Console display driver support ---> o [*] VGA text console

But nothing changed. Then, typing "Alt+SysRq+p" and "Alt+SysRq+t" (dump ?) return nothing. It is not clear whether the keyboard is recognized or not. (Only the "NumLock" key works.) Are there any other works ?

Thanks, I attached the files to the mail sent to you only (because of its large size). It is a tar compressed archive (L4Linux.tar) and the size of it is about 13MB.
o L4Linuxs : This directory includes binaries. The path is "/boot/L4Linuxs". o menu.lst : The GRUB menu list file (grub.conf).
By the way, the L4Linux binary without DOpE made with my old configuration (like one I sent few days ago, which produces a large
vmlinux binary) doesn't stop there. But it prints some errors on the way and then aborts (because of some modules ?). So, I think the cause of hanging is in the L4Linux configuration about some drivers, is it right ?

It hangs for me as well. Rebuilding my L4Linux tree with your configuration and using gcc-4.1 works for me. Building with gcc-3.4 hangs at the exact same place. Could you try another gcc version (preferably 4.1)?

I rebuilded the L4Linux with gcc-4.1.1, and made sure the boot sequence with it doesn't hang ! Thanks. BUT, I get a new error (the sequence isn't completed).

Do you get a prompt when you add a 'init=/bin/sh' to the Linux kernel command line? What type of Red Hat are you using? Seeing this for the first time.
I don't get a prompt. I use "Fedora 7 (2.6.21-1.3194.fc7)" in "/dev/hda1". And the "/bin/sh" in it is GNU bash 3.2.9 (i686-redhat-linux-gnu). The kernel command line values and their massage logs are the following:

The shell is exiting for some reason. I'd guess because /dev is kind of empty. I cannot check this right now, maybe tomorrow.

Yes, if not setting it the default init will be started.
And, do programs such as "/bin/sh" which runs on Fedora run also on L4Linux ?
Yes, L4Linux is binary compatible with native Linux.
You should try a ramdisk first to make sure something works. You can get one of the L4Linux site.

Ok, I see. Then, the init (of my Fedora on /sbin/init) should work on L4Linux normally, is it right ?

I had tried it but it also stops with the following message.

Should yes, and it does. I think something after init breaks.

The login-prompt appears on tty1, so either in the dope window or on the vga screen, depending what you are using.

The login-prompt appears on tty1, so either in the dope window or on the vga screen, depending what you are using.
Does it appear on tty1 only ? I'm using serial console(ttyLv0) now, and see the same messages as tty1. In this case, should I see login-prompt on serial console too ?
I have not gotten any prompts until now. My current settings is ...

Nearly...

No.
On Linux (and most Unices) there's a file called /etc/inittab which tells /sbin/init what to do. There are entries which define how the getties are started. The getties are those programs that give you the prompt. They have an argument that specifies the console they work on. The inittab in the ramdisk defines tty1, tty2, tty3, tty4, tty5 and tty6 for the getties. If you want to have the prompt on ttyLv0, you need to modify the /etc/inittab on the ramdisk accordingly.

That config gives you no tty1. You either need to enable dope to get a framebuffer and thus tty1 or without dope enable the keyboard and VGA to get tty1.

Thanks for your particular explanation. I have not seen the boot process of Linux in detail until now... I'll study harder.
I enabled keyboard and VGA support in Linux configuration and changed "console=ttyLv0" to "console=tty1" in the kernel command line. Then, I got the login prompt on tty1 and could use bash of the ramdisk on L4Linux finally ! :) It seems to operate well. I also tried using DOpE on tty1 without keyboard and VGA, then it works. I would like to express to you my deepest gratitude for having spent much time on taking care of my work.
Lastly, I have a small question. With keyboard and VGA support enabled, I get the following prompt on the serial console (not on tty1). (When I use DOpE, it doesn't appear because keyboard and VGA are disabled.)

This is just some debugging notice as some driver within L4Linux is requesting an io memory region that the IO manager in L4Env doesn't know anything about. The request thus just fails (so pressing g is ok in this case). There should be a message somewhere of the type: l4io_search_mem_region for phys_addr = xxxx which should state which physical address was requested.
The messages on tty1 at this time are the following.

I don't think you need the vga16fb.
Are there any problem in my kernel configuration or boot settings ? My now kernel configuration is the same as the recent mail (based on the given .config) :
Would be good to know the message from the failed io memory request.
