L4Linux (dm_phys?) problem
Hello, I have a problem with runnig L4Linux. On both native and ux, the error is similar. (see the following log) Before this problem happened, I didn't any problem. IMHO, dm_phys seems to be the source of this error. I tried different mode (uclibc, dietlibc) with the same error. Best regards, Jugwan 1) On ux ---------------------------------------------------------------------------------------------------------------------- zugwan@getgid:~/boot/l4.oskit/runux$ ./lx con /home/zugwan/boot/l4.oskit/fiasco/fiasco -m 256 -symbols /home/zugwan/boot/l4.oskit/fiasco/Symbols -lines /home/zugwan/boot/l4.oskit/fiasco/Lines -rmgr /home/zugwan/boot/l4.oskit/l4v2/rmgr-ux -symbols -lines -sigma0 /home/zugwan/boot/l4.oskit/l4v2/sigma0-ux -fb_program /home/zugwan/boot/l4.oskit/fiasco/ux_con -irq0 /home/zugwan/boot/l4.oskit/fiasco/irq0 -t 32768 -G 640x480@16 -l /home/zugwan/boot/l4.oskit/l4v2/names -l /home/zugwan/boot/l4.oskit/l4v2/log -l /home/zugwan/boot/l4.oskit/l4v2/dm_phys -l /home/zugwan/boot/l4.oskit/l4v2/simple_ts -l /home/zugwan/boot/l4.oskit/l4v2/fuxfprov -n9 -l /home/zugwan/boot/l4.oskit/l4v2/rtc-ux -n10 -l /home/zugwan/boot/l4.oskit/l4v2/l4exec -l /home/zugwan/boot/l4.oskit/l4v2/con-ux -n12 -l /home/zugwan/boot/l4.oskit/l4v2/loader /home/zugwan/boot/l4.oskit/l4v2/run /home/zugwan/boot/l4.oskit/cfg/l4linux26.ux Fiasco-UX on Linux 2.6.11 (i686) Native Syscall Map: 0x1600 Mapped 256 MB Memory + 4096 KB Framebuffer + 4 MB Input Area on FD 3 Loading Module 0x00090000-0x00095060 [/home/zugwan/boot/l4.oskit/l4v2/sigma0-ux] Loading Module 0x00100000-0x001c6220 [/home/zugwan/boot/l4.oskit/l4v2/rmgr-ux] Copying Module 0x0ea66000-0x0ea84685 [/home/zugwan/boot/l4.oskit/fiasco/Symbols] Copying Module 0x0ea33000-0x0ea65cdd [/home/zugwan/boot/l4.oskit/fiasco/Lines] Copying Module 0x0ea07000-0x0ea32a7e [/home/zugwan/boot/l4.oskit/l4v2/names] Copying Module 0x0e9df000-0x0ea066c1 [/home/zugwan/boot/l4.oskit/l4v2/log] Copying Module 0x0e97d000-0x0e9de1fb [/home/zugwan/boot/l4.oskit/l4v2/dm_phys] Copying Module 0x0e94d000-0x0e97cd2b [/home/zugwan/boot/l4.oskit/l4v2/simple_ts] Copying Module 0x0e8a4000-0x0e94cdc1 [/home/zugwan/boot/l4.oskit/l4v2/fuxfprov] Copying Module 0x0e880000-0x0e8a345d [/home/zugwan/boot/l4.oskit/l4v2/rtc-ux] Copying Module 0x0e784000-0x0e87fcfa [/home/zugwan/boot/l4.oskit/l4v2/l4exec] Copying Module 0x0e6b1000-0x0e783b26 [/home/zugwan/boot/l4.oskit/l4v2/con-ux] Copying Module 0x0e5ea000-0x0e6b0c9a [/home/zugwan/boot/l4.oskit/l4v2/loader] Bootstrapping...

I have a problem with runnig L4Linux. On both native and ux, the error is similar. (see the following log) Before this problem happened, I didn't any problem. IMHO, dm_phys seems to be the source of this error. I tried different mode (uclibc, dietlibc) with the same error.
Don't worry. Some bug crept in somewhere, we're investigating... Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/

Previous error is fixed. But, I still fail to run L4Linux. Plz, See the attached image and log. Best regards, Jugwan Eom

This softlockup usually happens when scheduling stops and the timer is still ticking. It should fire about 10 secs after scheduling halts. It's difficult to tell now what exactly happens. Can you enable IPC logging and show me some of logs, that could at least give a hint for further investigaion. Or tar up your files and put them somewhere online, so I can look at them.

Sorry, I'm too late. I enabled IPC logging, but I'm not sure what should I see in the trace buffer.

It's always doing the same, that should not be.

----------------------------------------------------------------------------------------------------- So, I put my files in <http://getgid.postech.ac.kr/l4.tar.gz>.
With your files I can see this behaviour as well. It's not the kernel, at least. But I can't see any further what it really is. In dispatch.c there's a #if 0 at the beginning of the file. Make that to #if 1 to enable the logging macros and rebuild. (Your source tree is up to date, right?) Now I'd like to see the trace log right after init has been started. You should make that image available, maybe I can dig a bit further this way. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/

I think I located the problem. I should hit everyone who uses the oskit mode. I just committed a fix which should hit our public repository tomorrow (earliest). Please consider using dietlibc mode with bootstrap/roottask... Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
