Either your confused, or not expressing what you want very well. What you describe is how qemu_irq works. The "upstream device" and "receiving device" are the same thing. The whole point of qemu_irq is to be able to send a single-bit signal without having to know or care where it's going. ie. when creating the board/cpu, you create the qemu_irq object with appropriate parameters. Then the device initiating the reset uses that qemu_irq object. If the device initiating the reset needs to pass additional information, then you're no longer dealing with a single bit of state, so I don't think qemu_irq is really appropriate. Paul
