| 60 | # "Map PCI MMIO as Cached"\r | |
| 61 | #\r | |
| 62 | # Due to the way Stage1 and Stage2 mappings are combined on Aarch64, and\r | |
| 63 | # because KVM -- for the time being -- does not try to interfere with the\r | |
| 64 | # Stage1 mappings, we must not set EFI_MEMORY_UC for emulated PCI MMIO\r | |
| 65 | # regions.\r | |
| 66 | #\r | |
| 67 | # EFI_MEMORY_UC is mapped to Device-nGnRnE, and that Stage1 attribute would\r | |
| 68 | # direct guest writes to host DRAM immediately, bypassing the cache\r | |
| 69 | # regardless of Stage2 attributes. However, QEMU's reads of the same range\r | |
| 70 | # can easily be served from the (stale) CPU cache.\r | |
| 71 | #\r | |
| 72 | # Setting this PCD to TRUE will use EFI_MEMORY_WB for mapping PCI MMIO\r | |
| 73 | # regions, which ensures that guest writes to such regions go through the CPU\r | |
| 74 | # cache. Strictly speaking this is wrong, but it is needed as a temporary\r | |
| 75 | # workaround for emulated PCI devices. Setting the PCD to FALSE results in\r | |
| 76 | # the theoretically correct EFI_MEMORY_UC mapping, and should be the long\r | |
| 77 | # term choice, especially with assigned devices.\r | |
| 78 | #\r | |
| 79 | # The default is to turn off the kludge; DSC's can selectively enable it.\r | |
