[Qemu-devel] [PATCH] qemu-iothread: IOThread supports the GMainContext event loop |
Date: |

From: Wang Yong<address@hidden>
IOThread uses AioContext event loop and does not run a GMainContext.
Therefore,chardev cannot work in IOThread,such as the chardev is
used for colo-compare packets reception.
This patch makes the IOThread run the GMainContext event loop,
chardev and IOThread can work together.
