I'm working on an interface between qemu and an in house testing suite
and one of the things I would like to do is tell qemu to run the guest
for a number of guest milliseconds and then pause execution of the
guest.
I do not want qemu to raise a debug exception. I just want it to pause

gpio pin. I need to make sure that it gets
called every time master device calls qemu_set_irq.
What's the mechanism behind this behavior and how can I deliver gpio
change to the slave?

I'd like to add a virtual device that is controlled by a couple of
GPIO pins on my controller (cortex-m4) and a serial port. I suppose I
can derive it from SSISlaveClass to make the new device a serial
slave.
But how do I connect GPIOs?
I want the slave device to be notified when guest firmware t
Is it that I need to add emulation for CP10 and CP11?

Sent it off as reply instead of reply all.. my bad.
I was also surprised that it was mid into an instruction. The code
works fine on STM32 but if FPU is not enabled on the STM32 then I
believe the code will fault in much the same way. I have had this
problem before and it was also hard faulting in
Is it possible to instantiate multiple CPUs of different architectures
and simuate them with different images at the same time? Some examples
include ARM socs with m3/m4 coprocessor core but also boards with
multiple processors where it is desirable to connect the chips over
for example virtual SPI
