how to debug a newly written system cal
 

Hi,
i added a new system call..helloworld...

i rebuild the kernel and when i try to use it, it is returning -1.

can any one tell me how to debug and know where things went wrong..

how to see the kernel log when this syscall is called...i wrote a println in my syscall..but couldnt find that in /var/log/dmesg...

Help me out here

THanks in advance...

I think you need to use 'printk' ...

i have given printk itself....but still icant see any logs

Try /var/log/messages
