I also used the experimental i2c multi-master patches from Klaus to make a i2c-netdev device that connects two separate QEMU instances through a socket and sends their i2c messages back and forth. I was able to test a basic MCTP transaction.

Yes. We would need to extend the Aspeed machines to instantiate
2 different SoCs (or more). This is something quite interesting
to design.

Yes. Please do.

Thanks,
