79  # "Map PCI MMIO as Cached"
80  #
81  # Due to the way Stage1 and Stage2 mappings are combined on Aarch64, and
82  # because KVM -- for the time being -- does not try to interfere with the
83  # Stage1 mappings, we must not set EFI_MEMORY_UC for emulated PCI MMIO
84  # regions.
85  #
86  # EFI_MEMORY_UC is mapped to Device-nGnRnE, and that Stage1 attribute would
87  # direct guest writes to host DRAM immediately, bypassing the cache
88  # regardless of Stage2 attributes. However, QEMU's reads of the same range
89  # can easily be served from the (stale) CPU cache.
90  #
91  # Setting this PCD to TRUE will use EFI_MEMORY_WB for mapping PCI MMIO
92  # regions, which ensures that guest writes to such regions go through the CPU
93  # cache. Strictly speaking this is wrong, but it is needed as a temporary
94  # workaround for emulated PCI devices. Setting the PCD to FALSE results in
95  # the theoretically correct EFI_MEMORY_UC mapping, and should be the long
96  # term choice, especially with assigned devices.
97  #
98  # The default is to turn off the kludge; DSC's can selectively enable it.
