I/O Fabric (MMIO) Map
Memory accesses targeting MMIO are routed by the I/O fabric to programmed PCI
ranges, or routed to the PCU by default (subtractive agent). Programmed PCI ranges
are moved within low or high MMIO, and most are disabled. Not all devices are
mapped to high MMIO.
Fixed MMIO is claimed by the Platform Control Unit (PCU). The default regions are
listed in
. The variable (movable) ranges are shown in
.
