yield-wait-for does not trigger the callback, it returns the arguments for the callback when yield-for-returns.

yield-wait-for returns values instead of calling an upcall, all registers return. This is similar to yield-no-wait, but it only returns r1.

The first u32 is always 3, and the rest are driver_number and subscribe_number?

In this unittest, this function basically returns the same thing everytime, is this okay? What should happen if we don't have the expected upcall?
