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