Hello! Sorry for the delayed reply.

Tables are something like 64K each. They hold mappings between device/event IDs and actual IRQ numbers. Unfortunately i don't know how to answer the second part of the question, about iterated part. Can you explain in details, what is it and how does it work? Or, well, we could put the question the other way: imagine that in pre_save i tell my emulated device to flush its cached state into RAM-based tables. In post_load i could tell the device to re-read data from RAM into its cache. So, what do i need in order to make these tables in RAM to migrate correctly?
