]does not address that issue at all.

This subject came up recently:

AMD processors have 8 mmio base/limit register pairs. Each pair
defines an address range as posted mmio or as non-posted mmio.
Somehow posted and non-posted ranges have to be allocated so
that they can be consolidated into a total of 8 or fewer ranges.
Then the mmio base/limit registers can be programmed to cover
the ranges.
