From a3919386eab91b56e40fb4faead980f57a664b2e Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Sat, 7 Feb 2015 09:38:44 +0100 Subject: [PATCH] Add GDB qAttached support With this patch QEMU handles qAttached request from gdb. When QEMU replies 1, GDB sends a "detach" command at the end of a debugging session otherwise GDB sends "kill". The default value for qAttached is 1 on system emulation and 0 on user emulation. Based on original version by Fabien Chouteau.
