That it mentions prefetchable memory is kind of minor: it's an address that requires 64-bit decoding, and it's an address that can be prefetched, but that's just the way the PCI device BAR is set. If the memory is prefetchable, it must also use 64-bit decoding. Prefetchable memory is the most efficient, so unless there are memory-mapped registers of a particular kind, it makes sense to always use 64-bit prefetchable memory. | That it mentions prefetchable memory is kind of minor: it's an address that requires 64-bit decoding, and it's an address that can be prefetched, but that's just the way the PCI device BAR is set.

In fact, none of the regions in these error messages use more than 32 bits anyway. | ||
