Hi,
is it possible to debug e.g. a x86-64 Linux kernel running in
qemu-system-x86_64 on a 32bit host from that host with GDB?
I cross-compiled a version of GDB with x86-64 support, so it can load
the debugging symbols from the kernel (which is an ELF64 binary) and
attached that to a running qemu-system-x86_64, but it always tells me
the instruction pointer is at 0x0.
Is this supported by QEMU?
Thanks,
Simon

Does the patch in
http://lists.gnu.org/archive/html/qemu-devel/2007-09/msg00062.html fix
it for you?
