I am getting the following error while compiling the l4linux 2.6 kernel that I got from cvs [root@orion l4linux-2.6]# make CHK include/linux/version.h make[1]: `arch/i386/kernel/asm-offsets.s' is up to date.

L4Linux bootprompt question
by Jayesh Salvi 09 Feb '05

09 Feb '05

Hi, I an confused about the bootprompt arguments mention in the l4linux.cd.k_us.cfg file that is given to the loader to load the L4Linux 2.6 kernel. The line is : task "vmlinuz26" "mem=44M noreplacement root=1:0 load_ramdisk=1 ramdisk_size=4096 l4env_rd=initrd.gz panicblink=0 lang=us" What does root=1:0 mean? After referring to "The Linux Bootprompt - HowTo" http://ldp.rtin.bz/HOWTO/BootPrompt-HOWTO-3.html#ss3.1 I figured out that the argument is of the type root=/dev/* Can anyone help me understand what "root=1:0" mean? This boot loading files are from the Fiasco-L4Linux boot cd available at http://os.inf.tu-dresden.de/L4/LinuxOnL4/demo.shtml Thanks. Jayesh

RE: GRUB
by Jayesh Salvi 04 Feb '05

04 Feb '05

I figured out the solution. To reinstall the grub you need to do grub-install /dev/hda This will write the stage1 to the MBR. Useful link for more GRUBbing: http://www.sims.berkeley.edu/~jhall/grub_install_hda1.html Thanks Jayesh _____ From: l4-hackers-bounces(a)os.inf.tu-dresden.de [mailto:l4-hackers-bounces@os.inf.tu-dresden.de] On Behalf Of Jayesh Salvi Sent: Wednesday, February 02, 2005 10:32 AM To: l4-hackers(a)os.inf.tu-dresden.de Subject: GRUB Hi, I downloaded the cvs module grub from os.inf.tu-dresden.de . I built the binaries. Doing make, make check, make install did not install this GRUB version (0.90..), my old gnu version (0.93) is what gets loaded when I restart the machine. I also ran the grub-install file from build/util directory: ./grub-install /dev/hda6 Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'. # this device map was generated by anaconda (fd0) /dev/fd0 (hd0) /dev/hda /dev/hda6 is where my " / " mounted.

Machine-independant handling of registers set with ptrace is tough.
by Etienne Robillard 31 Jan '05

31 Jan '05

Dear list, I'm actively into the process of hatching at the Fiasco-UX source-code, and have found the ptrace(2) interface to be quite entertaining. Firstly, the naming convention (ptrace macros) differs from Linux to FreeBSD. However, its relatively trivial to fix (thx to Alexander Julliard), by adding something like: #ifndef PTRACE_PEEKTEXT #define PTRACE_PEEKTEXT PT_READ_D #endif Secondly, a lot of things is done in `Usermode.cpp' in order to manipulate user-visible register set. In particular, I have to trust the effectiveness and the reliability of the following constructor: // save it to <machine/reg.h> struct user_regs_struct regs; regs.xfs = context->uc_mcontext.gregs[REG_FS] In comparison, the FreeBSD kernel implements the ptrace(2) proc_[read/write]_register(proc,regs) for doing this kind of stuff, but its not even close to be a member of uc_mcontext. All in all, it would be nice to know how (and why) this is done on different arch, and finally if the uc_mcontext.gregs constructor is the sole alternative to registers translation. Cheers, Etienne ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

Fiasco-UX build problem

Hi, I have a problem building Fiasco-UX. After checking out the latest sources, i had to do two workarounds to build all packages and the oskit.

L4Linux and serial port access from other tasks
by Julian Grizzard 26 Jan '05

26 Jan '05

Hi all, I'm running L4Linux on the Fiasco V2 microkernel on a Pentium IV. I am also running other L4 applications beside the L4Linux kernel. I would like to be able to print debug messages from those applications to the serial port. Messages print fine until L4Linux boots up. As best as I can determine, the problem is that L4Linux gets control of the serial port, and so no other tasks can use it. There may be a way to get this working using the L4Env setup; however, I am trying to keep a very minimal setup and so do not want to use L4Env. Can anyone provide some pointers on how to best go about restricting L4Linux's access to the serial port? Thanks! -Julian
