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


From: Max Filippov
Subject: [Qemu-devel] [PATCH v2] gdbstub: allow killing QEMU via vKill command
Date: Wed, 30 Jan 2019 11:24:03 -0800

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")

Cc: Luc Michel <address@hidden>

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