+ # "Map PCI MMIO as Cached"
+ #
+ # Due to the way Stage1 and Stage2 mappings are combined on Aarch64, and
+ # because KVM -- for the time being -- does not try to interfere with the
+ # Stage1 mappings, we must not set EFI_MEMORY_UC for emulated PCI MMIO
+ # regions.
+ #
+ # EFI_MEMORY_UC is mapped to Device-nGnRnE, and that Stage1 attribute would
+ # direct guest writes to host DRAM immediately, bypassing the cache
+ # regardless of Stage2 attributes. However, QEMU's reads of the same range
+ # can easily be served from the (stale) CPU cache.
+ #
+ # Setting this PCD to TRUE will use EFI_MEMORY_WB for mapping PCI MMIO
+ # regions, which ensures that guest writes to such regions go through the CPU
+ # cache. Strictly speaking this is wrong, but it is needed as a temporary
+ # workaround for emulated PCI devices. Setting the PCD to FALSE results in
+ # the theoretically correct EFI_MEMORY_UC mapping, and should be the long
+ # term choice, especially with assigned devices.
+ #
+ # The default is to turn off the kludge; DSC's can selectively enable it.
