# "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.
