2012-10-30aio: introduce AioContext, move bottom halves therePaolo Bonzini
Start introducing AioContext, which will let us remove globals from aio.c/async.c, and introduce multiple I/O threads. The bottom half functions now take an additional AioContext argument. A bottom half is created with a specific AioContext that remains the same throughout the lifetime. qemu_bh_new is just a wrapper that uses a global context.

2011-12-05coroutine: add qemu_co_queue_restart_all()Stefan Hajnoczi
It's common to wake up all waiting coroutines. Introduce the qemu_co_queue_restart_all() function to do this instead of looping over qemu_co_queue_next() in every caller. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-08-02coroutines: Use one global bottom half for CoQueueKevin Wolf
Now that AsyncContexts don't exist any more, we can use one global bottom half for restarting coroutines instead of allocating a new one every time (before removing AsyncContexts, the problem with having a global BH was that it had to belong to a single AsyncContexts and wouldn't be executed in a different one - which leads to deadlocks) Signed-off-by: Kevin Wolf <kwolf@redhat.com>
