The "region overlap" problem in the L4/Fiasco hello example
by chenggh 12 Aug '06

12 Aug '06

Hi,everyone: When I boot the hello example in the L4/Fiasco. there is a "region overlap" in the booting information. I don't why it could be like this. The grub configuration and the error information is following: Grub: title fiasco_hello_new kernel (hd0,1)/boot/fiasco_hello_new/bootstrap -comport 1 -serial module (hd0,1)/boot/fiasco_hello_new/main -nokdb module (hd0,1)/boot/fiasco_hello_new/sigma0 module (hd0,1)/boot/fiasco_hello_new/roottask module (hd0,1)/boot/… [View More]

The future of L4
by Guillaume FORTAINE 31 Jul '06

31 Jul '06

Hello all, I believe it's time to use ne tools to develop a robust l4 based os. here are my suggestions : c++ multithreaded language : http://plg.uwaterloo.ca/~usystem/uC++.html c++ library : http://cxx.uclibc.org/ Could we replace glibc with uclibc++ and ntpl with the uc++ language ? build system : http://www.exactcode.de/oss/exact-build/index.html parrallel and asychronous api: https://gforge.inria.fr/projects/kaapi/ (scheduler and api for l4) => focused on performance : could … [View More]

where are the headers?
by Alan Grimes 20 Jul '06

20 Jul '06

I'm planning out how to port Minix to L4 and I can't find any of the hearders. http://tudos.de/l4env/doc/html/bid-tut/node2.html I have CVS'd just about everything on your downloads page yet ./l4/include, ./l4/lib and ./l4/bin do not exist. I feel that many of the choices regarding the layout of the source code and the usage of the more sophisticated tools only serve to obfuscate the system to new users. =( -- Don't let your schoolwork get in the way of your learning. ### NEW E-MAIL: agrimes(a)speakeasy.net ###

gdb on Fiasco
by FERANDELLE Pascal 13 Jul '06

13 Jul '06

I took a copy of the floppy demo image on the Fiasco site, and try to use gdb on fiasco, from a PC/Linux with serial line, and gdb 6.4. I create a new grub entry to launch fiasco without the flags -noserial, -nowait and -nokdb, and the hello module. Boot seems ok, I suppose fiasco enters kdb and waits for a connexion from the serial line. On the PC/Linux, I launch gdb, and enter commands : set remotebaud 115200 target remote /dev/ttyS0 A dialog seems to establish with the target as I have … [View More]

Running L4Linux on fiasco-ux?
by Michael J. Emswiler 05 Jul '06

05 Jul '06

Is it possible to run l4linux under fiasco-ux with X-11 apps? I am just testing various scenarios and playing around getting familiar with how things work. Here is the command I tried and the results : ./fiasco -G 1024x768@16 -m 256 -l names -l "dm_phys --mem=0x01400000,0x0a000000,0xffffffff" -l l4dope-ux -l l4ovlwm -l "vmlinuz26.ux mem=128M root=/dev/hda1 no-scroll" And the end result was: <snip> Roottask: Loading 5 modules. #05: loading "names" from [0ea3f000-0ea8440c] to [… [View More]
