Going to support Advanced Interrupt Architecture(AIA) ? #1574

I wonder if spike is going to support Advanced Interrupt Architecture(AIA) in the future? because I am developing related software but have no simulatior supporting AIA. Thanks

I'm not aware of anyone planning to add support for it, but I agree it would be nice to have.

The AIA includes three parts, i.e., 1) Smcsrind/Sscsrind extension, 2) Smaia/Ssaia extension, and 3) IMSIC/APLIC device. Spike has an initial implementation for the Smcsrind/Sscsrind extension. I am working on the Smaia/Ssaia extension and aiming to fire a PR next month. I wonder whether Spike would be interested in the IMSIC/APLIC device.

I continue developing the Smaia/Ssaia extension and anticipate requiring a few more weeks.
