[Qemu-devel] [PATCH v2] gdbstub: allow killing QEMU via vKill command

[Max Filippov <jcmvbkbc@gmail.com>]

With multiprocess extensions gdb uses 'vKill' packet instead of 'k' to
kill the inferior. Handle 'vKill' the same way 'k' was handled in the
presence of single process.

Fixes: 7cf48f6752e5 ("gdbstub: add multiprocess support to
(f|s)ThreadInfo and ThreadExtraInfo")

Changes v1->v2:
- terminate QEMU in the vKill packet handler regardless of whatever the
  PID is or how many processes are attached [Luc Michel]
