[L4 on realview Cortex A9] Failing on board check during fiasco bootup
Hello Guys, I was attempting to run fiasco built for CortexA9/realview-pbx board on qemu. "qemu-system-arm" version used for this experimentation is "QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5)" L4 Code used "l4re-core-2011020417" with hello world example. Below are the messages which i got when i tried to run fiasco on qemu - 1st set of logs I tried to comment the check inside Board_check::check_board() in the hope that it might boot up, but later i got crash for qemu (hw mismatch ?) - 2nd set of logs *1st set of logs* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ L4 msgs specifying invalid sys id~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ novino@naveen-linux:~/L4/l4re-core-2011020417/src/l4/mybuild-realview-pbx-a9/images$ qemu-system-arm -M realview-pbx-a9 -cpu cortex-a9 -kernel bootstrap_hello.elf -m 256 -nographic -net nic -net user L4 Bootstrapper Build: #2 Thu Feb 10 18:21:42 MVT 2011, 4.5.1 Scanning up to 256 MB RAM ........some messages .....

The board-check passes on the real board. If I remember right it didn't really work as the real board last time I tried but that's some time ago. Things might have changed, I should retry. Anyway, any particular reason you want to use that config? 'realview-eb' should just work fine. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
Dear Adam/L4hackers, I've tried running realview-eb against L4 kernel built for arm926EJ and it runs smoothly without any glitches :) I was trying to run L4 for the smp variant (esp cortex a9 to be precise). As per the qemu documentation "realview-eb" - doesn't support support cortex a9, the one which i needed was with smp more than 1 (2 or 4) { Eg: novino@naveen-linux:~/L4/l4re-core-2011020417/src/l4/mybuild-realview-eb-a9/images$ qemu-system-arm -M realview-eb -cpu cortex-a9 -kernel bootstrap_hello.elf -m 256 -nographic -net nic -net user -smp 4 Number of SMP cpus requested (4), exceeds max cpus supported by machine `realview-eb' (1) } However when i try to run any variant of L4 built for cortex a9 i'm getting stuck at the time of execution.

I looked a bit closer to that now and I'm afraid to tell that running MP on Qemu requires some extra coding work in Qemu itself.

Dear Adam, Actually when we tried qemu for running "smp linux", and it ran fine with "realview-pbx-a9" board with "-smp 4". Where it booted up with 4 core configuration. For the same reason we were selected "realview-pbx-a9" board configuration when doing "make config" for L4 microkernel under the assumption that it would run. But the board check itself is failing afterwards (for qemu). If you could recommend any board which can be used for the "multicore development" it would be great :). We really liked the documentation and the code support which is available with fiasco group for the same reason we wanted to have fiasco as our primary candidate for experimentations. Please let me know if with some effort we would be able to bring up the multicore microkernel, i might be able to help out in case some effort is required for the unimplemented part.

Yes, it works with Linux as Linux was (likely) used for developing this. I've got a hack running internally now and posting patches upstream... Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
Dear Adam, We were able to overcome the qemu: fatal: Unimplemented cp15 register write (c9, c14, {0, 0}) by modifying helper.c in qemu code (cleaned c9 data reg) and L4 booting went ahead till it starts Sigma0. But as you pointed out earlier (for smp running) that cp15-c7 implementation/data structure(qemu:Cpu.h) is missing (which doesn't looks like it'll be implimented anytime sooner in qemu). The patch/workaround which you've mentioned, i'm supposing is a L4 patch for overcoming qemu's shortcoming. Where can i access this patch/hack (as part of next release or in SVN) ? Once i'm free, will check on qemu side if i can help in impl of Cp15-c7, but with my limited knowledge on arm side it'll take a while.

But the board check itself is failing afterwards (for qemu). If you could recommend any board which can be used for the "multicore development" it would be great :).
We really liked the documentation and the code support which is available with fiasco group for the same reason we wanted to have fiasco as our primary candidate for experimentations. Please let me know if with some effort we would be able to bring up the multicore microkernel, i might be able to help out in case some effort is required for the unimplemented part.
Yes, it works with Linux as Linux was (likely) used for developing this. I've got a hack running internally now and posting patches upstream...

We were able to overcome the qemu: fatal: Unimplemented cp15 register write (c9, c14, {0, 0}) by modifying helper.c in qemu code (cleaned c9 data reg) and L4 booting went ahead till it starts Sigma0.
Those are performance counters which can be disabled altogether. There isn't just an option for that currently because it was always available so far.
But as you pointed out earlier (for smp running) that cp15-c7 implementation/data structure(qemu:Cpu.h) is missing (which doesn't looks like it'll be implimented anytime sooner in qemu).
No, it has been implemented. Patch reviews are currently going on on the qemu list. It will probably still take a bit until it hits git.
The patch/workaround which you've mentioned, i'm supposing is a L4 patch for overcoming qemu's shortcoming. Where can i access this patch/hack (as part of next release or in SVN) ?
I'm not trying to add workarounds to Fiasco but to add the missing bits to qemu. The next svn refresh will probably contain those little bits for not requiring perfcounters. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/

To make things quicker, patch that applies on current head of qemu.git is here: http://os.inf.tu-dresden.de/~adam/dl/qemu-arm.diff Latest version of Fiasco from SVN is also required. Then it should work. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
Thanks a lot Adam, With this qemu patch, the emulation over realview-pbx-a9 board with "-smp 4" is working fine. Cheers, Naveen On Tue, Feb 22, 2011 at 4:54 AM, Adam Lackorzynski < adam@os.inf.tu-dresden.de> wrote:
