1d0f:1237 are the subsystem vendor and device ids of the i440fx emulation in the EC2 machine model, which is what we're using for:
Today, the EC2 machine model isn't open source.
So I guess not based on qemu? Otherwise you would have some GPL issues ...
How big are the differences to qemu? Does it have fw_cfg?
Should we have a separate PF_EC2 flag?
However, we're not excluding the option of making it generally available in the future.
That would be good. Sometimes it is quite helpful to see the host-side changes when reviewing firmware patches.
