L4Linux bootprompt question
by Jayesh Salvi 08 Feb '05

08 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

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 .

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. First i got the following error: ... make[3]: Entering directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit/examples' ld -Ttext 100000 -L../lib \ -o multiboot ../lib/multiboot.o multiboot.o \ -lkern -lmc -llmm ../lib/crtn.o /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/libgcc.a ld -Ttext 100000 -L../lib \ -o multiboot-gdb ../lib/multiboot.o multiboot-gdb.o \ -lkern -lmc -llmm ../lib/crtn.o /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/libgcc.a ld -Ttext 100000 -L../lib \ -o multiboot-smp ../lib/multiboot.o multiboot-smp.o \ -lsmp -lkern -lmc -llmm ../lib/crtn.o /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/libgcc.a ../lib/libsmp.a(boot.o)(.text+0x29): In function `_SMP_TRAMP_START_': : relocation truncated to fit: R_386_16 _SMP_TRAMP_32_ENTRY_ make[3]: *** [multiboot-smp] Error 1 make[3]: Leaving directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit/examples' make[2]: *** [examples/all.MAKE] Error 2 make[2]: Leaving directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/sk852421/Documents/uni/OS/Fiasco-UX/oskit' make: *** [../oskit] Error 2 the Makeconf.bid can you find here: http://www.inf.tu-dresden.de/~sk852421/fiasco/Makeconf.bid and the full make output is here: http://www.inf.tu-dresden.de/~sk852421/fiasco/make.out So i deleted subdirectory examples and modified GNUmakefile.

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

L4Linux on AMD NF7-S

Hi. I'm trying to get l4linux to run on an AMD Athlon with a NF7-S mother board. I have managed to get linux to run, but only by removing the PCI bus support from the kernel completely. Other attempts at compiling the kernel have resulted in one of two errors when loading: loader | module path <(nd)/fiasco/hdboot> loader | <vmlinuz.l4env>, args <l4irqack=linux mem=64M no-scroll load_ramdisk= loader : 1 ramdisk_size=16384 root=/dev/ram0 ro l4env_rd=(nd)/fiasco/drops-rd. loader : rd> loader | <vmlinuz.l4env>: priority: a0 exec | vmlinuz.l4env: Loading tftp | Loading (nd)/fiasco/hdboot/vmlinuz.l4env [1146kB] exec | vmlinuz.l4env: Too many (>4) loadable program sections loader | vmlinuz.l4env: Error -2001 (EXEC: Invalid file format) while loading loader | ==> App successfully purged OR, Linux version 2.4.28-l4 (root@magenta) (gcc version 3.3.4 (Debian 1:3.3.4-9ubuntu5)) #99 Thu Jan 13 16:18:11 SAST 2005 69MB LOWMEM available. hm, page 00000000 reserved twice.

build report for Drops on FBSD
by Etienne Robillard 12 Jan '05

12 Jan '05

Hi, Here's the summary of what I've done to (almost) compile drops on FreeBSD 5.3-STABLE. - in l4/tool/gendep/syscall.c: Added #ifdef linux to wrap around missing <asm/unistd.h>. - Added $(LDFLAGS) to l4/tool/gendep/Makefile. - Told libgendep.so to link with `perl -MExtUtils::Embed -e ldopts` instead of '-ldl'. - Needed to configure drops with cpp33 instead of cpp0. - In $(OSKIT)/boot/boot_start.c, gcc complained about missing "" characters, so I added a bunch of them. - In $(L4DIR)/mk/Makeconf, I've added FIND=/usr/local/bin/gfind to avoid confusion with FreeBSD find (/usr/bin/find). I've told mk/include.mk to use $(FIND). Here's the latest official build-problem I've encountered: ...
