*	iothread: stash thread ID away	Stefan Hajnoczi	2014-03-13	1	-0/+22
\| \| \| \| \| \| \| \| \| \| \| \| \|	Keep the thread ID around so we can report it via QMP. There's only one problem: qemu_get_thread_id() (gettid() wrapper on Linux) must be called from the thread itself. There is no way to get the thread ID outside the thread. This patch uses a condvar to wait for iothread_run() to populate the thread_id inside the thread. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
*	iothread: add I/O thread object	Stefan Hajnoczi	2014-03-13	1	-0/+120
	This is a stand-in for Michael Roth's QContext. I expect this to be replaced once QContext is completed. The IOThread object is an AioContext event loop thread. This patch adds the concept of multiple event loop threads, allowing users to define them. When SMP guests run on SMP hosts it makes sense to instantiate multiple IOThreads. This spreads event loop processing across multiple cores. Note that additional patches are required to actually bind a device to an IOThread. [Andreas Färber <afaerber@suse.de> pointed out that the embedded parent object instance should be called "parent_obj" and have a newline afterwards. This patch has been changed to reflect this. -- Stefan] Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
