root task - debugging kernel
by Etienne Robillard 22 May '03

22 May '03

Hi, How do we define printf in ia32-v4 ? I see there is a print.cc implementation but it won't be used(?) for the linking stage even with "#define CONFIG_KDB y" and or "#define CONFIG_VERSION_X0 1" in $(OBJ)/config.h... Besides, kickstarting from grub (output to screen) does work until the "Launching kernel stage" ; then it freezes without warnings :-) my menu.lst looks like this : root (hd0,1,a) kernel= /boot/ia32-kernel module=/libexec/l4/kickstart module= /libexec/l4/sigma0 module= /libexec/l4/pingpong cya etienne ===== iD ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

Hi l4-hackers admins: > SIE HABEN DAS PRODUKT - WIR IHRE ZUK\NFTIGEN KUNDEN. > > http://www.Adress-Schmiede.de I'm also getting a lot of SPAM from those people.

They use different IP addresses from the same pool. You may contact T-Online AG regarding this. I'm pretty sure that this is not in accordance with their (T-Online's) AUP.

compiling L4Env with oskit for Fiasco and L4Linux
by Etienne Robillard 06 May '03

06 May '03

Hello everyone, My name is Etienne Robillard and I am studying Art in college. I don't have yet any degree in computers science, whatsoever. What I am attempting to do is to build/boot L4Linux (and on another time The Hurd, while I'm at it...) on a typical x86 machine, Pentium III with 384mb of sdram. oskit = oskit60 (the old version modified for l4 with patches) gcc = crossgcc 2.95.2 (no libgcc2.a) with pthread-elf support, i386/linux emulation os = freebsd4.7-p8 (with libc_r/) make = gmake target = i586-l4-linux (just for fun...) build= i386-unknown-freebsd4.7 binutils = version 2.13.2.1 as root in $(L4DIR); gmake hello : gmake[1]: Entering directory `/home/manoya/build/l4oskit/l4/oskit/flux' gmake[1]: Nothing to be

As a result, I am quite lost in space with the asm part. But, I was asking myself if 1) this is due to an improper crosscompiler setup (compiler doesnt have libgcc2.a subroutines... my fault) Will work on that for now on. 2) because I have undef HAVE_CODE16, my i16_bcopy object will fail bit-copying inline functions that need 16 bit index base ? 3) "warning: control reaches end of non-void function" and "fixed or forbidden register 2 (cx) was spilled for class CREG" Yeah. right. Bring it Linda ! Here is for your convenience a sample of the contents of $(OSKIT)/libfdev_linux/include/asm/string.h:408 #define __HAVE_ARCH_MEMCPY #define memcpy(t, f, n) \ (__builtin_constant_p(n) ? \ __constant_memcpy((t),(f),(n)) : \ <------ n=count ? __memcpy((t),(f),(n))) /* I have tried to change (n) to (count) with similar syndromes; but something's telling me that Linus know what he`s doing while I seriously doubt my proefficiency in that domain... */ Also, I dont have an Internet connection at home... Therefore, I got very, very old parts (before 1.0) of the Fiasco �-kernel... At last, this issue in lfdev_linux might be solved already(?), which would be nice, but I haven't found any references to that neither in the 2001 mailing-list or in the 2002.

hello: i execute the l4_thread_ex_regs(...) systemcall, then the stack been pushed 0x38 byte data (esp -0x38), what`s that ? most serious is if i execute the l4_thread_ex_regs( dest_thread_id, child,... ) systemcall then the |child| running ,but if i execute l4_myself() in |child|, the return value is not equal to dest_thread_id, is that means i can`t specific the dest thread id or it`s unnecessary to spicify the dest thread id in the caller thread, but managed by |child| itself ?
