I feel the same way too, even 'til now :) The way I do it is maybe counter intuitive for you. I compile the kernel image with frame pointer enabled and debug info (check kernel hacking section in "make config" during kernel compilation). Then, together with a disk image, I run this kernel in Qemu virtual machine. While running, I hook gdb to this Qemu instance. Finally, I put breakpoints, watchpoints, check backtraces etc I needed to understand the flow. Maybe that'll work for you too. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
