so Im debugging a kernel,
running inside virtme (I cant recommend it enough)
using 2 terminals, each in build-dir
1st runs
function dkrunk () {
echo vm $KRUN_SHOW $KRUN_STDS $KDBG_OPTS $* $QM_OPTS --smp 3 -s -S
virtme-run $KRUN_SHOW $KRUN_STDS $KDBG_OPTS $* $QM_OPTS --smp 3 -s -S
# -qmp tcp:localhost:4444,server,nowait
}
2nd runs:
alias tui='gdb --tui -q -x ../../../gdb-2 vmlinux'
that script is
# seems I need a hardware breakpoint to get started,
# is that the case for anyone else ?
hbreak dynamic_debug_init
c
b strcmp if cs == ct
c
If you do this, youll find all the places where
strcmp is called on identical args.
Most of them I dont want to see,
but what kind of syntax lets me look up the frame(s)
to select only the contexts of interest ?
it would be useful enough to test just the caller file,
that would get me a long way
