I don't know. Can I mmap kcore, set up a function that I want to try out before putting in the kernel, have it modify the variables that are mmapped, and see if all works? Also, I've only used /proc/kcore with gdb, I never wrote my own core parsing programs. I like to do some strange things when adding stuff to the kernel, and mapping /dev/mem to get to kernel globals from user space was one of them. I didn't just monitor, I did modify things as well. But this was all for R&D and testing. Never for the final product, so that's why I don't mind a config option, even under kernel debug. -- Steve - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
