IOThread is a general framework that contains IO loop environment and a
|
|
|
4a2fec |
real thread behind. It's also good to be used internally inside qemu.
|
|
|
4a2fec |
Provide some helpers for it to create iothreads to be used internally.
|
|
|
4a2fec |
|
|
|
4a2fec |
Put all the internal used iothreads into the internal object container.
