Device 2 IO

Size:
MMIO_INDEX: A 32 bit IO write to this port loads the offset of the MMIO register or
offset into the GTT that needs to be accessed. An IO Read returns the current value of
this register. An 8/16 bit IO write to this register is completed by the CPU UNCORE
but does not update this register.
This mechanism to access internal graphics MMIO registers must not be used to
access VGA IO registers which are mapped through the MMIO space. VGA registers
must be accessed directly through the dedicated VGA IO ports.
