i'm aware of a number of ways to debug kernel space variables from
user space, but i'm not sure there's a way to do it if you're
extremely limited in the information you have at hand.
the scenario: a running 64-bit fedora 11 system. there is no
"vmlinux" file at hand -- all i have is the vmlinuz file representing
the running kernel. i have "gdb" installed, and there exist the files
/proc/kcore and /proc/kallsyms. but given only that, is there any way
to list the current value of, say, the kernel variable "jiffies"?
i can see in /proc/kallsyms the entry
ffffffffff600880 D __jiffies
but without the vmlinux file, i don't think gdb will do me any good.
or am i misremembering?
