[Qemu-devel] [RFC PATCH v1 2/7] qom/cpu.c: Encapsulate cpu halting


From: Peter Crosthwaite
Subject: [Qemu-devel] [RFC PATCH v1 2/7] qom/cpu.c: Encapsulate cpu halting
Date: Mon, 4 Mar 2013 19:01:34 +1000

Set up the Device level halting API to halt cpus. This allows holders of a
pointer to the CPU to halt it from the TYPE_DEVICE abstraction. (i.e. they
can halt it even if they dont know its a CPU).
