This region is exported at /machine/smram. It is "empty" if SMRAME=0 and points to SMRAM if SMRAME=1. The CPU will enable/disable it as it enters or exits SMRAM. While touching nearby code, the existing memory region setup was slightly inconsistent. The smram_region is *disabled* in order to open SMRAM (because the smram_region shows the low VRAM instead of the RAM at 0xa0000). Because SMRAM is closed at startup, the smram_region must be enabled when creating the i440fx or q35 devices. Acked-by: Michael S.
