Hi,
On reporting a breakpoint in a non-non-stop mode, GDB remotes must stop
all threads. Currently qemu-user doesn't do that, breaking the
debugging session for at least two reasons: concurrent access to the
GDB socket, and an assertion within GDB [1].
This series fixes this by importing pause_all_vcpus() from qemu-system.
This in turn requires introducing BQL and a few stubs to qemu-user.
I would have expected you to reuse (some portion of) start_exclusive, which is already
part of qemu-user. Is there a reason you chose a solution which requires...
replay: Add replay_mutex_{lock,unlock}() stubs for qemu-user
qemu-timer: Provide qemu_clock_enable() stub for qemu-user
cpu: Use BQL in qemu-user
all sorts of other infrastructure?
