Problem booting l4linux on pistachio
by Gordon 22 Dec '04

22 Dec '04

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. I am selecting the "tamed" option when making. My grub menu.lst contains the following lines: title L4Ka::Pistachio kernel /kickstart module /ia32-kernel module /sigma0 module /vmlinuz.VX2 no-scroll console=herc console=tty I get the following messsage and error: init_emulibpager initialized to c0001 --- "unable to map generic bootinfo" --- --------------------------------- (eip=00600d3f, esp=005edf98) --- Then I type g (go) at the L4 prompt and get more info: L4Linux: init_l4_resource_management empty bootmem: f000000, c0400000 start_pfn=f000000, bootmap_size = 18080 Linux version 2.4.22-l4-dev (root@khaki) (gcc version 3.3.4 (Debian 1:3.3.4-9ubuntu5)) #2 Tue Dec 24 Request of the genetic bootinfo 00020000:000283ff failed.

proxygon problem

Hi. Using proxygon i'm able to load applications like hello and vscrtest, but as soon as I try to load l4linux I get the following error on the serial port: hello: My thread-id is 12.0 hello: My thread-id is 14.0 proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. hello: My thread-id is 12.0 hello: My thread-id is 14.0 proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. proxygon| called con_vc_direct_update_component - not yet implemented. l4linux would load when I was still using doperun. I'v been attempting to load l4linux using a file with the following: verbose 2 modpath "(nd)/fiasco" task "run" task "vmlinuz.l4env" "root=/dev/hda3 ro l4irqack=linux" Any suggestions? Thanx Steve -- sbrobson(a)fastmail.fm

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
