Problem building the Pistachio 0.4 kernel
by Andreas Grosam 10 Jan '05

10 Jan '05

Hi All, this is my first attempt to compile the kernel. After installing L4/Pistachio and the tool chain for building a PowerPC kernel (on a PowerBook G4), i got this error message while compiling the kernel sources: pistachio-0.4/kernel/include/glue/v4-powerpc/tcb.h:330: error: can't find a register in class `GENERAL_REGS' while reloading `asm' I'm using gcc-3.4.3 as the cross compiler - compiled with the Apple tools. It doesn't seem that this error has something to do with the sources - more likely it is compiler related. I'm not a compiler guru, thus googling for that error message revealed some more information. Unfortunately no suggested solution for that specific problem seems appropriate. Furthermore, it turned out that this might be an optimization bug in the compiler. When using -O1 optimization when building the kernel (default is -Os), this error disappears. With stronger optimization it comes back. Do you have an idea how to workaround this error (gcc patches or prior versions, etc.)? Thanks in advance for any help! Regards Andreas

Network server + l4linux NIC stub driver
by sbrobson＠fastmail.fm 06 Jan '05

06 Jan '05

Hi all, I'm working on an system that runs multiple instances of l4linux. I would however like to set it up so that these instances share a network card, by means of a network server and stub driver interface. I have found a number of papers refering to such setups, including a reference to an OshKosh Network driver. Are such network servers available? Where can I get hold of one? Regards, steve. -- sbrobson(a)fastmail.fm

Problem booting l4linux on pistachio

Hi I am trying to boot l4linux (2.4.22 from CVS, checked out on 25/06/2004) from Pistachio (CVS checkout 20/12/2004). I am using gcc 3.3.4. for compiling Pistachio and l4linux.

L4Linux 2.4 IRQ problem
by Carsten Weinhold 15 Dec '04

15 Dec '04

Hi all! I'm trying to get L4Linux 2.4 running. It starts to boot, but then it runs into trouble attaching to interrupts: -------------------------------- ... l4lx_irq_dev_startup: Starting IRQ thread for IRQ 5. l4lx | l4lx_thread_create: Created thread 0f.11 (IRQ5) l4lx_irq_dev_startup: Starting IRQ thread for IRQ 4. l4lx | l4lx_thread_create: Created thread 0f.12 (IRQ4) l4lx_irq_dev_startup: Starting IRQ thread for IRQ 3. l4lx | l4lx_thread_create: Created thread 0f.13 (IRQ3) l4lx_irq_dev_startup: Starting IRQ thread for IRQ 2. l4lx | l4lx_thread_create: Created thread 0f.14 (IRQ2) hda: ST317221A, ATA DISK drive hda: IRQ probe failed (0xfffc) hdb: IRQ probe failed (0xfffc) hdb: IRQ probe failed (0xfffc) hdc: IRQ probe failed (0xfffc) acquire_irq: Error attaching to IRQ 1 ---------------------------------- After these messages L4Linux enters Fiasco's kernel debugger (thread f.06). There seem to be 2 problems, the first one is that L4Linux has difficulties accessing the IDE controller. The second is related to IRQ 1. This happens on two different machines, so it's probably a configuration issue. However, I don't know where to start in order to fix this. Greetings, Carsten ------------- menu.lst entry used to boot L4Linux --------------- title L4Linux-2.4 on L4Env kernel $(P)/rmgr -sigma0 task modname "L4Linux task" modaddr 0x02000000 module $(P)/main -nowait -nokdb -serial_esc -comspeed 115200 -comport 1 module $(P)/sigma0 module $(P)/names module $(P)/log module $(P)/dm_phys module $(P)/rtc module $(P)/simple_ts -t 300 module $(P)/l4io --noirq #module $(P)/con --l4io module $(P)/tftp -i module $(P)/l4exec module $(P)/loader $(P)/l4linux.l4env #vbeset $(VBE_MODE) ------------- loader config file for L4Linux --------------- task "l4linux.l4env" "l4irqack=linux mem=256M no-scroll root=/dev/hda3 l4env_rd=$(P)/drops.rd" priority 0xA0

L4 come together at 21C3 in Berlin?
by Michael Engel 10 Dec '04

10 Dec '04

Hi, I just browsed through the 21C3 conference program - http://www.ccc.de/congress/2004/fahrplan-preview/fahrplan.html - and saw that at least some of the people involved in L4 development will be in Berlin (and, the better, give interesting talks). So, this is a good excuse to attend 21C3 (and let the University pay for it :-)) - are there eventually more L4 hackers attending the congress? Perhaps we could organize something like a BoF session... Btw., does anyone have a proposal for an inexpensive place to stay in Berlin from the 27th to the 30th of December? regards, Michael
