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. 99 # 100 gArmVirtTokenSpaceGuid.PcdKludgeMapPciMmioAsCached|FALSE|BOOLEAN|0x00000006 101
