QemuVideoDxe installs its own legacy INT 10h handler for the benefit of
systems like Windows 2008r2 which attempt to use INT 10h even when booted
via EFI.
This interacts extremely badly with a CSM actually attempting to install
a real video BIOS.
The last thing done before invoking a legacy OpROM is to call INT 10h to
set a plain text mode. In the case where it's the video BIOS OpROM being
loaded, INT 10h will normally point to an iret stub in the CSM itself.
Unless QemuVideoDxe has changed INT10h to point to a location in the
0xC0000 segment that it didn't allocate properly, so the real OpROM has
been shadowed over them top of it, and the INT 10h vector now points to
some random place in the middle of the newly-shadowed OpROM.
Don't Do That Then. QemuVideoDxe doesn't do any acceleration and just
sets up a linear framebuffer, so we don't lose much by just
unconditionally using BiosVideoDxe instead when CSM is present.

According to the discussion at:
https://edk2.groups.io/g/devel/topic/30918343#38093
For OVMF, we keep both ISA stacks:
* The legacy one in PcAtChipsetPkg/IntelFrameworkModulePkg
* The Sio bus based OVMF-specified one introduced by commit a5cc178aeb
for a period of time (includes 1 stable tag: edk2-stable201905). And we
also keep the Sio bus based OVMF-specified stack as the default one (via a
build option 'USE_LEGACY_ISA_STACK') to validate its stability.
This commit will propose to drop the legacy ISA stack from OVMF and remove
the usage of the build flag 'USE_LEGACY_ISA_STACK' at the same time. This
is considered as a preparation for the removal of
PcAtChipsetPkg/IsaAcpiDxe & IntelFrameworkModulePkg.

This patch adds the TCG2 Configuration menu to the Device Manager
menu. We can apparently reuse the sample Tcg2ConfigDxe from
SecurityPkg/Tcg/Tcg2Config without obvious adverse effects. The
added TCG2 Configuration menu now shows details about the attached
TPM 2.0 and lets one for example configure the active PCR banks
or issue commands, among other things.
The code is added to Ovmf by building with -DTPM2_ENABLE and
-DTPM2_CONFIG_ENABLE.

BLOCK_MMIO_PROTOCOL and BlockMmioToBlockIoDxe were introduced to OvmfPkg
in March 2010, in adjacent commits b0f5144676 and efd82c5794. In the
past eight years, no driver or application seems to have materialized that
produced BLOCK_MMIO_PROTOCOL instances. Meanwhile the UEFI spec has
developed the EFI_RAM_DISK_PROTOCOL, which edk2 implements (and OVMF
includes) as RamDiskDxe.
Rather than fixing issues in the unused BlockMmioToBlockIoDxe driver,
remove the driver, together with the BLOCK_MMIO_PROTOCOL definition that
now becomes unused too.

sha384 :
The PhysicalPresenceLib is required, it sets some variables, but the
firmware doesn't act on it yet.
Laszlo Ersek explained on the list why Tpm2DeviceLib has to be
resolved differently for DXE_DRIVER modules in general and for
"Tcg2Dxe.inf" specifically:
* We have a library class called Tpm2DeviceLib -- this is basically the
set of APIs declared in "SecurityPkg/Include/Library/Tpm2DeviceLib.h".
Its leading comment says "This library abstract how to access TPM2
hardware device".
There are two *sets* of APIs in "Tpm2DeviceLib.h":
(a) functions that deal with the TPM2 device:
- Tpm2RequestUseTpm(),
- Tpm2SubmitCommand()
This set of APIs is supposed to be used by clients that *consume*
the TPM2 device abstraction.
(b) the function Tpm2RegisterTpm2DeviceLib(), which is supposed to be
used by *providers* of various TPM2 device abstractions.
* Then, we have two implementations (instances) of the Tpm2DeviceLib class:
(1) SecurityPkg/Library/Tpm2DeviceLibTcg2/Tpm2DeviceLibTcg2.inf
(2) SecurityPkg/Library/Tpm2DeviceLibRouter/Tpm2DeviceLibRouterDxe.inf
(1) The first library instance ("Tpm2DeviceLibTcg2.inf") implements the
APIs listed under (a), and it does not implement (b) -- see
EFI_UNSUPPORTED. In other words, this lib instance is strictly meant for
drivers that *consume* the TPM2 device abstraction. And, the (a) group
of APIs is implemented by forwarding the requests to the TCG2 protocol.
The idea here is that all the drivers that consume the TPM2 abstraction
do not have to be statically linked with a large TPM2 device library
instance; instead they are only linked (statically) with this "thin"
library instance, and all the actual work is delegated to whichever

(2) The second library instance ("Tpm2DeviceLibRouterDxe.inf") is meant

* Here's how things fit together:
(i) The "SecurityPkg/Library/Tpm2DeviceLibDTpm/Tpm2InstanceLibDTpm.inf"
library instance (which has no lib class) is linked into "Tcg2Dxe.inf"
via NULL class resolution. This simply means that before the
"Tcg2Dxe.inf" entry point function is entered, the constructor function
of "Tpm2InstanceLibDTpm.inf" will be called.
(ii) This Tpm2InstanceLibDTpmConstructor() function calls API (b), and
registers its own actual TPM2 command implementation with the
"Tpm2DeviceLibRouter" library instance (also linked into the Tcg2Dxe
driver). This provides the back-end for the API set (a).

land in Tcg2Dxe, via the protocol.
(v) Tcg2Dxe serves the protocol request by forwarding it to API set (a)
from lib instance (2).
(vi) Those functions call the "backend" functions registered by
Tpm2DeviceLibDTpm in step (ii).

* So that is the "router" pattern in edk2. Namely,
- Consumers of an abstraction use a thin library instance.
- The thin library instance calls a firmware-global (singleton) service,
i.e. a PPI (in the PEI phase) or protocol (in the DXE phase).
- The PEIM providing the PPI, or the DXE driver providing the protocol,
don't themselves implement the actual service either. Instead they
offer a "registration" service too, and they only connect the incoming
"consumer" calls to the earlier registered back-end(s).
- The "registration service", for back-ends to use, may take various
forms.
It can be exposed globally to the rest of the firmware, as
another member function of the PPI / protocol structure. Then backends
can be provided by separate PEIMs / DXE drivers.
Or else, the registration service can be exposed as just another
library API. In this case, the backends are provided as NULL class
library instances, and a platform DSC file links them into the PEIM /
DXE driver via NULL class resolutions. The backend lib instances call
the registration service in their own respective constructor
functions.

The Tcg2ConfigPei module informs the firmware globally about the TPM
device type, by setting the PcdTpmInstanceGuid PCD to the appropriate
GUID value. The original module under SecurityPkg can perform device
detection, or read a cached value from a non-volatile UEFI variable.
OvmfPkg's clone of the module only performs the TPM2 hardware detection.
This is what the module does:
- Check the QEMU hardware for TPM2 availability only
- If found, set the dynamic PCD "PcdTpmInstanceGuid" to
&gEfiTpmDeviceInstanceTpm20DtpmGuid. This is what informs the rest of
the firmware about the TPM type.
- Install the gEfiTpmDeviceSelectedGuid PPI. This action permits the
PEI_CORE to dispatch the Tcg2Pei module, which consumes the above PCD.
In effect, the gEfiTpmDeviceSelectedGuid PPI serializes the setting
and the consumption of the "TPM type" PCD.
- If no TPM2 was found, install gPeiTpmInitializationDonePpiGuid.
(Normally this is performed by Tcg2Pei, but Tcg2Pei doesn't do it if
no TPM2 is available. So in that case our Tcg2ConfigPei must do it.)

(1) In the PEI phase, the PCD database is maintained in a GUID HOB. In
OVMF, we load the PCD PEIM before any other PEIMs (using APRIORI PEI),
so that all other PEIMs can use dynamic PCDs. Consequently,
- the PCD GUID HOB is initially allocated from the temporary SEC/PEI
heap,
- whenever we introduce a dynamic PCD to a PEIM built into OVMF such
that the PCD is new to OVMF's whole PEI phase, the PCD GUID HOB (and
its temporary heap footprint) grow.
I've noticed that, if we add just one more dynamic PCD to the PEI
phase, then in the X64 build,
- we get very close to the half of the temporary heap (i.e., 8192
bytes),
- obscure PEI phase hangs or DXE core initialization failures
(ASSERTs) occur. The symptoms vary between the FD_SIZE_2MB and
FD_SIZE_4MB builds of X64 OVMF.
(2) I've found that commit
2bbd7e2fbd ("UefiCpuPkg/MtrrLib: Update algorithm to calculate

(3) OVMF's temp SEC/PEI RAM size has been 32KB ever since commit
7cb6b0e068 ("OvmfPkg: Move SEC/PEI Temporary RAM from 0x70000 to
0x810000", 2014-01-21)
Of that, the upper 16KB half is stack (growing down), and the lower
16KB half is heap.
Thus, OvmfPkg/PlatformPei's calls to "UefiCpuPkg/Library/MtrrLib", in
QemuInitializeRam(), cause the Scratch array to overflow the entire
stack (heading towards lower addresses), and corrupt the heap below
the stack. It turns out that the total stack demand is about 24KB, so
the overflow is able to corrupt the upper 8KB of the heap. If that
part of the heap is actually used (for example because we grow the PCD
GUID HOB sufficiently), mayhem ensues.
(4) Right after commit 7cb6b0e068 (see above), there would be no room
left above the 32KB temp SEC/PEI RAM. However, given more recent
commits
45d8708151 ("OvmfPkg/PlatformPei: rebase and resize the permanent
PEI memory for S3", 2016-07-13)
6b04cca4d6 ("OvmfPkg: remove PcdS3AcpiReservedMemoryBase,

we can now restore the temp SEC/PEI RAM size to the original
(pre-7cb6b0e06809) 64KB. This will allow for a 32KB temp SEC/PEI
stack, which accommodates the ~24KB demand mentioned in (3).
(Prior patches in this series will let us monitor the stack usage in
the future.)

Due to security reasons all DMA operations inside the SEV guest must

When the GenFv utility from BaseTools composes a firmware volume, it
checks whether modules in the firmware volume are subject to build-time
relocation. The primary indication for relocation is whether the firmware
volume has a nonzero base address, according to the [FD] section(s) in the
FDF file that refer to the firmware volume.
The idea behind build-time relocation is that XIP (execute in place)
modules will not be relocated at boot-time:
- Pre-DXE phase modules generally execute in place.
(OVMF is no exception, despite the fact that we have writeable memory
even in SEC: PEI_CORE and PEIMs run in-place from PEIFV, after SEC
decompresses PEIFV and DXEFV from FVMAIN_COMPACT (flash) to RAM.
PEI_CORE and the PEIMs are relocated at boot-time only after PlatformPei
installs the permanent PEI RAM, and the RAM migration occurs.)
- Modules dispatched by the DXE Core are generally relocated at boot-time.
However, this is not necessarily so. Quoting Liming from
<https://lists.01.org/pipermail/edk2-devel/2017-July/012053.html>:
> PI spec has no limitation that XIP is for PEIM only. DXE driver may be
> built as XIP for other purpose. For example, if DXE driver image address
> is not zero, DxeCore will try allocating the preferred address and load
> it. In another case, once DXE driver is relocated at build time, DxeCore
> will dispatch it and start it directly without loading, it may save boot
> performance.
Therefore GenFv relocates even DXE and UEFI driver modules if the
containing firmware volume has a nonzero base address.
In OVMF, this is the case for both PEIV and DXEFV:
> [FD.MEMFD]
> BaseAddress = $(MEMFD_BASE_ADDRESS)
> Size = 0xB00000
> ErasePolarity = 1
> BlockSize = 0x10000
> NumBlocks = 0xB0
> ...
> 0x020000|0x0E0000
> gUefiOvmfPkgTokenSpaceGuid.PcdOvmfPeiMemFvBase|gUefiOvmfPkgTokenSpaceGuid.PcdOvmfPeiMemFvSize
> FV = PEIFV
>
> 0x100000|0xA00000
> gUefiOvmfPkgTokenSpaceGuid.PcdOvmfDxeMemFvBase|gUefiOvmfPkgTokenSpaceGuid.PcdOvmfDxeMemFvSize
> FV = DXEFV
While the build-time relocation certainly makes sense for PEIFV (see
above), the reasons for which we specify DXEFV under [FD.MEMFD] are
weaker:
- we set the PcdOvmfDxeMemFvBase and PcdOvmfDxeMemFvSize PCDs here,
- and we ascertain that DXEFV, when decompressed by SEC from
FVMAIN_COMPACT, will fit into the area allotted here, at build time.
In other words, the build-time relocation of the modules in DXEFV is a
waste of resources. But, it gets worse:
Build-time relocation of an executable is only possible if the on-disk and
in-memory layouts are identical, i.e., if the sections of the PE/COFF
image adhere to the same alignment on disk and in memory. Put differently,
the FileAlignment and SectionAlignment headers must be equal.
For boot-time modules that we build as part of edk2, both alignment values
are 0x20 bytes. For runtime modules that we build as part of edk2, both
alignment values are 0x1000 bytes. This is why the DXEFV relocation,
albeit wasteful, is also successful every time.
Unfortunately, if we try to include a PE/COFF binary in DXEFV that
originates from outside of edk2, the DXEFV relocation can fail due to the
binary having unmatched FileAlignment and SectionAlignment headers. This
is precisely the case with the E3522X2.EFI network driver for the e1000
NIC, from Intel's BootUtil / PREBOOT.EXE distribution.
The solution is to use the FvForceRebase=FALSE override under [FV.DXEFV].
This tells GenFv not to perform build-time relocation on the firmware
volume, despite the FV having a nonzero base address.
In DXEFV we also have SMM drivers. Those are relocated at boot-time (into
SMRAM) unconditionally; SMRAM is always discovered at boot-time.
Kudos to Ard and Liming for the PE/COFF sections & relocations
explanation, and for the FvForceRebase=FALSE tip.
I regression-tested this change in the following configurations (all with
normal boot and S3 suspend/resume):
IA32, q35, SMM, Linux
IA32X64, q35, SMM, Linux
IA32X64, q35, SMM, Windows-8.1

In the Platform Init v1.4a spec,
- Volume 1 "4.7 Status Code Service" defines the
EFI_PEI_SERVICES.ReportStatusCode() service,
- Volume 1 "6.3.5 Status Code PPI (Optional)" defines the
EFI_PEI_PROGRESS_CODE_PPI (equivalent to the above),
- Volume 2 "14.2 Status Code Runtime Protocol" defines the
EFI_STATUS_CODE_PROTOCOL.
These allow PEIMs and DXE (and later) modules to report status codes.
Currently OvmfPkg uses modules from under
"IntelFrameworkModulePkg/Universal/StatusCode/", which produce the above
abstractions (PPI and PROTOCOL) directly, and write the status codes, as
they are reported, to the serial port or to a memory buffer. This is
called "handling" the status codes.
In the Platform Init v1.4a spec,
- Volume 3 "7.2.2 Report Status Code Handler PPI" defines
EFI_PEI_RSC_HANDLER_PPI,
- Volume 3 "7.2.1 Report Status Code Handler Protocol" defines
EFI_RSC_HANDLER_PROTOCOL.
These allow several PEIMs and runtime DXE drivers to register callbacks
for status code handling.
MdeModulePkg offers a PEIM under
"MdeModulePkg/Universal/ReportStatusCodeRouter/Pei" that produces both
EFI_PEI_PROGRESS_CODE_PPI and EFI_PEI_RSC_HANDLER_PPI, and a runtime DXE
driver under "MdeModulePkg/Universal/ReportStatusCodeRouter/RuntimeDxe"
that produces both EFI_STATUS_CODE_PROTOCOL and EFI_RSC_HANDLER_PROTOCOL.
MdeModulePkg also offers status code handler modules under
MdeModulePkg/Universal/StatusCodeHandler/ that depend on
EFI_PEI_RSC_HANDLER_PPI and EFI_RSC_HANDLER_PROTOCOL, respectively.
The StatusCodeHandler modules register themselves with
ReportStatusCodeRouter through EFI_PEI_RSC_HANDLER_PPI /
EFI_RSC_HANDLER_PROTOCOL. When another module reports a status code
through EFI_PEI_PROGRESS_CODE_PPI / EFI_STATUS_CODE_PROTOCOL, it reaches
the phase-matching ReportStatusCodeRouter module first, which in turn
passes the status code to the pre-registered, phase-matching
StatusCodeHandler module.
The status code handling in the StatusCodeHandler modules is identical to
the one currently provided by the IntelFrameworkModulePkg modules. Replace
the IntelFrameworkModulePkg modules with the MdeModulePkg ones, so we can
decrease our dependency on IntelFrameworkModulePkg.

In the next patch we're going to put EFI_PEI_MP_SERVICES_PPI to use.
CpuMpPei uses the following PCDs from gUefiCpuPkgTokenSpaceGuid, beyond
those already used by CpuDxe:
- PcdCpuMicrocodePatchAddress and PcdCpuMicrocodePatchRegionSize: these
control whether CpuMpPei performs microcode update. If the region size
is zero, then the microcode update is skipped. UefiCpuPkg.dec sets the
region size to zero by default, which is appropriate for OVMF.
- PcdCpuApLoopMode and PcdCpuApTargetCstate: the former controls how
CpuMpPei puts the APs to sleep: 1 -- HLT, 2 -- MWAIT, 3 -- busy wait
(with PAUSE). The latter PCD is only relevant if the former PCD is 2
(MWAIT). In order to be consistent with SeaBIOS and with CpuDxe itself,
we choose HLT. That's the default set by UefiCpuPkg.dec.
Furthermore, although CpuMpPei could consume SecPeiCpuExceptionHandlerLib
technically, it is supposed to consume PeiCpuExceptionHandlerLib. See:
- http://thread.gmane.org/gmane.comp.bios.edk2.devel/12703
- git commit a81abf1616 ("UefiCpuPkg/ExceptionLib: Import

Jeff recommended to resolve CpuExceptionHandlerLib to
PeiCpuExceptionHandlerLib for all PEIMs:
- http://thread.gmane.org/gmane.comp.bios.edk2.devel/14471/focus=14477
Since at the moment we have no resolution in place that would cover this
for PEIMs (from either [LibraryClasses] or [LibraryClasses.common.PEIM]),
it's easy to do.

No module in OvmfPkg uses these PCDs any longer.
The first PCD mentioned is declared by OvmfPkg, so we can remove even the

The second PCD comes from IntelFrameworkModulePkg. The module that
consumes PcdS3AcpiReservedMemorySize is called
"IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe", and it is built

depends on the feature PCD called PcdFrameworkCompatibilitySupport, which
we never enable in OVMF.
The 32KB gap that used to be the S3 permanent PEI memory is left unused in

After IncompatiblePciDeviceSupportDxe, this is another small driver /
protocol implementation that tweaks the behavior of the PCI bus driver in
edk2.
The protocol is specified in the Platform Init Spec v1.4a, Volume 5,
Chapter 12.6 "PCI Hot Plug PCI Initialization Protocol". This
implementation steers the PCI bus driver to reserve the following
resources ("padding") for each PCI bus, in addition to the BARs of the
devices on that PCI bus:
- 2MB of 64-bit non-prefetchable MMIO aperture,
- 512B of IO port space.
The goal is to reserve room for devices hot-plugged at runtime even if the
bridge receiving the device is empty at boot time.
The 2MB MMIO size is inspired by SeaBIOS. The 512B IO port size is
actually only 1/8th of the PCI spec mandated reservation, but the
specified size of 4096 has proved wasteful (given the limited size of our
IO port space -- see commit bba734ab4c). Especially on Q35, where every
PCIe root port and downstream port qualifies as a separate bridge (capable
of accepting a single device).
Test results for this patch:
- regardless of our request for 64-bit MMIO reservation, it is downgraded
to 32-bit,
- although we request 512B alignment for the IO port space reservation,
the next upstream bridge rounds it up to 4096B.

The FDF spec mentions the FvNameGuid statement for [FV.xxxx] sections, but
the detailed description can be found in Volume 3 of the Platform Init
spec (which is at 1.4a currently).
Adding an FvNameGuid statement to [FV.xxx] has the following effects
(implemented by "BaseTools/Source/C/GenFv/GenFvInternalLib.c"):
- The EFI_FIRMWARE_VOLUME_HEADER.ExtHeaderOffset field is set to a nonzero
value, pointing after EFI_FIRMWARE_VOLUME_HEADER itself (although not
directly, see below).
- An EFI_FIRMWARE_VOLUME_EXT_HEADER object is created at the pointed-to
address. This object is not followed by any
EFI_FIRMWARE_VOLUME_EXT_ENTRY (= extension) entries, so it only
specifies the Name GUID for the firmware volume.
The EFI_FIRMWARE_VOLUME_EXT_HEADER for each firmware volume can be found
in the Build directory as a separate file (20 bytes in size):
Build/Ovmf*/*_GCC*/FV/*.ext
- The new data consume 48 bytes in the following volumes: SECFV,
FVMAIN_COMPACT, DXEFV. They comprise:
- 16 padding bytes,
- EFI_FFS_FILE_HEADER2 (8 bytes in total: no Name and ExtendedSize
fields, and Type=EFI_FV_FILETYPE_FFS_PAD),
- EFI_FIRMWARE_VOLUME_EXT_HEADER (20 bytes, see above),
- 4 padding bytes.
(The initial 16 padding bytes and the EFI_FFS_FILE_HEADER2 structure are
the reason why EFI_FIRMWARE_VOLUME_HEADER.ExtHeaderOffset does not point
immediately past EFI_FIRMWARE_VOLUME_HEADER.)
The sizes of the firmware volumes don't change, only their internal
usages grow by 48 bytes. I verified that the statements and calculations
in "OvmfPkg/DecomprScratchEnd.fdf.inc" are unaffected and remain valid.
- The new data consume 0 bytes in PEIFV. This is because PEIFV has enough
internal padding at the moment to accomodate the above structures
without a growth in usage.
In the future, firmware volumes can be identified by Name GUID (Fv(...)
device path nodes), rather than memory location (MemoryMapped(...) device
path nodes). This is supposed to improve stability for persistent device
paths that refer to FFS files; for example, UEFI boot options.

According to edk2 commit
"MdeModulePkg/PciBus: do not improperly degrade resource"
and to the EFI_INCOMPATIBLE_PCI_DEVICE_SUPPORT_PROTOCOL definition in the
Platform Init 1.4a specification, a platform can provide such a protocol
in order to influence the PCI resource allocation performed by the PCI Bus
driver.
In particular it is possible instruct the PCI Bus driver, with a
"wildcard" hint, to allocate the 64-bit MMIO BARs of a device in 64-bit
address space, regardless of whether the device features an option ROM.
(By default, the PCI Bus driver considers an option ROM reason enough for
allocating the 64-bit MMIO BARs in 32-bit address space. It cannot know if
BDS will launch a legacy boot option, and under legacy boot, a legacy BIOS
binary from a combined option ROM could be dispatched, and fail to access
MMIO BARs in 64-bit address space.)
In platform code we can ascertain whether a CSM is present or not. If not,
then legacy BIOS binaries in option ROMs can't be dispatched, hence the
BAR degradation is detrimental, and we should prevent it. This is expected
to conserve the 32-bit address space for 32-bit MMIO BARs.
The driver added in this patch could be simplified based on the following
facts:
- In the Ia32 build, the 64-bit MMIO aperture is always zero-size, hence
the driver will exit immediately. Therefore the driver could be omitted
from the Ia32 build.
- In the Ia32X64 and X64 builds, the driver could be omitted if CSM_ENABLE
was defined (because in that case the degradation would be justified).
On the other hand, if CSM_ENABLE was undefined, then the driver could be
included, and it could provide the hint unconditionally (without looking
for the Legacy BIOS protocol).
These short-cuts are not taken because they would increase the differences
between the OVMF DSC/FDF files. If we can manage without extreme
complexity, we should use dynamic logic (vs. build time configuration),
plus keep conditional compilation to a minimum.

- USE_OLD_BDS requires duplicating updates between OVMF's library
instances that depend on USE_OLD_BDS being FALSE vs. TRUE. Examples:

- OVMF doesn't build with "-D USE_OLD_BDS -D HTTP_BOOT_ENABLE" anyway, as
NetworkPkg/HttpBootDxe now requires UefiBootManagerLib:

option.
We (correctly) don't resolve UefiBootManagerLib when USE_OLD_BDS is
TRUE.
- The new BDS has been working well; for example it's the only BDS

The RamDiskDxe driver in MdeModulePkg now will use EFI_ACPI_TABLE_PROTOCOL
and EFI_ACPI_SDT_PROTOCOL during reporting RAM disks to NVDIMM Firmware
Interface Table (NFIT).
A Pcd 'PcdInstallAcpiSdtProtocol' controls whether the
EFI_ACPI_SDT_PROTOCOL will be produced. Its default value is set to FALSE
in MdeModulePkg. To make the NFIT reporting feature working properly under
OVMF, the patch will set the Pcd to TRUE in OVMF DSC files.
Also, the RamDiskDxe driver will sometimes report a NVDIMM Root Device
using ASL code which is put in a Secondary System Description Table (SSDT)
according to the ACPI 6.1 spec.
Locating the SSDT requires modifying the [Rule.Common.DXE_DRIVER] field in
OVMF FDF files.
