There is already an SMBus BMC device that can sit on the I2C bus. It's
in mainstream qemu now.
It does not have smbus alert support, though. I have patches for that,
but qemu doesn't have a flexibly general interrupt infrastructure, so I
hacked something in, and it's likely to be contentious. The trouble is
that the interrupt is disconnected from any real device, and qemu
doesn't handle that very well. And like the other things, I really only
created it for my testing.
For doing what you are trying to do, I don't think you need any special
support on either side for SSIF to work.
