Hello all, How can i debug early kernel booting, even before early_printk (x86_64). I'm interesting in part which starts to execute right after bootloader (https://github.com/torvalds/linux/blob/master/arch/x86/boot/header.S#L297). How to do it better? Write grub and vmlinuz to disk with losetup/grub-install and connect with gdb, or there is something another way to do it? Thank you. -- To unsubscribe from this list: send the line "unsubscribe linux-newbie" 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.linux-learn.org/faqs
