Hi, I am having an issue with getting a CPU external interrupt to occur from my own device model. The custom device is a set of registers than can be read and written to. The plan is whenever a particular register is written into, an external interrupt will occur.
I tried to use the function cpu_interrupt() inside the register write callback function but QEMU crashes when that occurs. The reason I tried it this way is because I found a post stating the success made with using the cpu_interrupt function (https://stackoverflow.com/questions/14869317/arm-interrupt-handling-in-qemu). After that attempt I added an interrupt controller in my own hardware model. But right now I am unclear with how to cause my external device to kick off an interrupt. Is there a certain function I can call when the register is written into that will cause an external interrupt? Any suggestions or guidance would be appreciated. Thanks!
