Emulating STM32F407 (Cortex-M4) with peripherals on an X86

Hi

I am new to the Qemu project and was wondering if it is possible to emulate the above processor with it's peripherals (Uart, DMA at least) on an X86.
Would it be possible for the following OS to run in a Qemu emulation (as it does on the real processor) ?

I want to see how many such devices would interact with each other over a network and it's unviable to have dozens of embedded boards at a time.

Generally all these processors have more functionality than pins, so the pins are multiplexed and must be assigned functionality in a startup routine. So i think there must be a CPU+peripheral emulator running on a board emulator.

I would like to know if anyone has attempted something like this before or some thoughts on the best way forward.

Regards
Srinath
