Dear All,

I learn from Internet that GDB would be used to debug the user space application and the KGDB would be used to debu ther linux kernel and module. If I want to debug a user space applicaiton, its function calls some of the system calls. What the debug tools could I use to trace the calling procedure form user space application to the system call inside the kernel and then return back to the user space application? Please share your debugging experiences with me. Thanks a lot.

Best Regards,
Riker.
