RFC: https://lists.gnu.org/archive/html/qemu-devel/2023-12/msg02044.html RFC -> v1: Use /proc/self/mem and accept that this will not work without /proc. Factor out a couple functions for gdbstub testing. Add a test.
Hi, I've noticed that gdbstub behaves differently from gdbserver in that it doesn't allow reading non-readable pages. This series improves the situation by using the same mechanism as gdbserver: /proc/self/mem. If /proc is not mounted, we fall back to the today's implementation.
