|
# "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.
