Hi,

I would like to announce that I have implemented a asynchronous I/O
framework for the MINGW port of QEMU to Windows.

Currently supported devices are timer, console and stdio serial devices,
and the gdb server stub.  I am also working on a telnet serial device.

The framework is designed to handle Windows COMx: and LPTy: devices
asynchronously (among other things), but I doubt that I will find time
to implement these.

Owing to the infelicities of the Windows NT operating system, a second
thread is required to handle asynchronous events, also, the stdio serial
device requires a separate thread.

The framework has been tested in a limited environment, namely QEMU for
ARM without graphics and with only an in-house operating system (my use
case).  However, I am not aware of having broken anything.

Unfortunately, I need to receive clearance to post the patches, this
will consume some time.

However, you might consider not expending effort in this direction until
I can release these patches.

Regards,

Konrad Schwarz
