7f17a15 (2024/02/22)
"OvmfPkg: Shell*.inc: allow building without network support"
breaks building OVMF with `-D NETWORK_ENABLE=0`.
Before this commit we could build OVMF e.g. with the following
command in the OvmfPkg directory:
./build.sh -D NETWORK_ENABLE=0
After the commit the same command fails early with:
/home/user/OpenSource/edk2/OvmfPkg/OvmfPkgX64.dsc(15):
error F001: Pcd (gEfiNetworkPkgTokenSpaceGuid.PcdAllowHttpConnections)
defined in DSC is not declared in DEC files referenced in INF files in
FDF. Arch: ['X64']
The problem applies in Intel OvmfPkg platforms.
Additionally, it applies in various other OvmfPkg
platforms, but is masked buy another issue; namely
that these platforms incorrectly still include some
network packages when most are disabled.
(A fix for that issue has previously been
made, in OvmfPkg Intel platforms only, by
d933ec1 followed by
7f17a15 .)
This commit conditionally removes the undefined Pcd references
in all OvmfPkg platforms which are now affected by this
issue, and in all those which would be affected as and
when the other issue mentioned above is fixed.

Add OvmfRng include snippets with the random number generator
configuration for OVMF. Include RngDxe, build with BaseRngLib,
so the rdrand instruction is used (if available).
Also move VirtioRng to the include snippets.
Use the new include snippets for OVMF builds.

There are below 2 differences between AMD & OVMF according
existing implementation:
1.The mode of the CPU check is different between the AMD & OVMF.
OVMF:
CpuSaveState->x86.SMMRevId & 0Xffff
AMD:
LMAValue = (UINT32)AsmReadMsr64 (EFER_ADDRESS) & LMA
2.Existing SmBase configuration is different between the
AMD & OVMF.
OVMF:
if ((CpuSaveState->x86.SMMRevId & 0xFFFF) == 0) {
CpuSaveState->x86.SMBASE = mSmBaseForAllCpus[CpuIndex];
} else {
CpuSaveState->x64.SMBASE = mSmBaseForAllCpus[CpuIndex];
}
AMD:
AmdCpuState->x64.SMBASE = mSmBaseForAllCpus[CpuIndex];
This patch provides the SmmRelocationLib library instance
for OVMF to handle the logic difference, and it won't change
the existing implementation code logic.

For the most part, OVMF will clear the encryption bit for MMIO regions,
but there is currently one known exception during SEC when the APIC
base address is accessed via MMIO with the encryption bit set for
SEV-ES/SEV-SNP guests. In the case of SEV-SNP, this requires special
handling on the hypervisor side which may not be available in the
future[1], so make the necessary changes in the SEC-configured page
table to clear the encryption bit for 4K region containing the APIC
base address.

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654
Add initial support for the new AmdSvsmLib library to OvmfPkg. The initial
implementation fully implements the library interfaces.
The SVSM presence check, AmdSvsmIsSvsmPresent(), determines the presence
of an SVSM by checking if an SVSM has been advertised in the SEV-SNP
Secrets Page.
The VMPL API, AmdSvsmSnpGetVmpl(), returns the VMPL level at which OVMF is
currently running.
The CAA API, AmdSvsmSnpGetCaa(), returns the Calling Area Address when an
SVSM is present, 0 otherwise.
The PVALIDATE API, AmdSvsmSnpPvalidate(), copies the PVALIDATE logic from
the BaseMemEncryptSevLib library for the initial implementation. The
BaseMemEncryptSevLib library will be changed to use this new API so that
the decision as to whether the SVSM is needed to perform the operation
can be isolated to this library.
The VMSA API, AmdSvsmSnpVmsaRmpAdjust(), copies the RMPUPDATE logic from
the MpInitLib library for the initial implementation. The MpInitLib
library will be changed to use this new API so that the decision as to
whether the SVSM is needed to perform the operation can be isolated to
this library.

NullMemoryTestDxe was included in the OVMF platforms in historical commit
999a815e9ff3 ("OvmfPkg: Add NullMemoryTestDxe driver", 2011-01-21). It
produces gEfiGenericMemTestProtocolGuid. With LegacyBiosDxe gone, the only
consumer of this protocol in all of edk2 is
"EmulatorPkg/Library/PlatformBmLib/PlatformBmMemoryTest.c". Thus, exclude
NullMemoryTestDxe from all OVMF platforms.
(Notably, ArmVirtPkg platforms don't include NullMemoryTestDxe either.)

- `"varpolicy -?"` shows help text
- `"varpolicy -b"` pages output as expected
- `"varpolicy -s"` shows accurate variable statistic information

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504
The BaseRngLibTimerLib allows to generate number based on a timer.
This mechanism allows to have a basic non-secure implementation
for non-production platforms.
To bind and identify Random Number Generators implementations with
a GUID, an unsafe GUID should be added. This GUID cannot be added
to the MdePkg unless it is also added to a specification.
To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to
the MdeModulePkg. This will allow to define an unsafe Rng GUID
in a later patch in the MdeModulePkg.
The MdePkg implementation will be removed later. This allows to give
some time to platform owners to switch to the MdeModulePkg
implementation.

introduced, this library is updated to support #VE as well. Now the name
of VmgExitLib cannot reflect what the lib does.
This patch renames VmgExitLib to CcExitLib (Cc means Confidential
Computing). This is a simple renaming and there is no logic changes.
After renaming all the VmgExitLib related codes are updated with
CcExitLib. These changes are in OvmfPkg/UefiCpuPkg/UefiPayloadPkg.

Following the Hardware Info library, create the DxeHardwareInfoLib
which implements the whole API capable of parsing heterogeneous hardware
information. The list-like API grants callers a flexible and common
pattern to retrieve the data. Moreover, the initial source is a BLOB
which generalizes the host-to-guest transmission mechanism.
The Hardware Info library main objective is to provide a way to
describe non-discoverable hardware so that the host can share the
available resources with the guest in Ovmf platforms. This change
features and embraces the main idea behind the library by providing
an API that parses a BLOB into a linked list to retrieve hardware
data from any source. Additionally, list-like APIs are provided so
that the hardware info list can be traversed conveniently.
Similarly, the capability is provided to filter results by specific
hardware types. However, heterogeneous elements can be added to the
list, increasing the flexibility. This way, a single source, for
example a fw-cfg file, can be used to describe several instances of
multiple types of hardware.
This part of the Hardware Info library makes use of dynamic memory
and is intended for stages in which memory services are available.
A motivation example is the PciHostBridgeLib. This library, part
of the PCI driver populates the list of PCI root bridges during DXE
stage for future steps to discover the resources under them. The
hardware info library can be used to obtain the detailed description
of available host bridges, for instance in the form of a fw-cfg file,
and parse that information into a dynmaic list that allows, first to
verify consistency of the data, and second discover the resources
availabe for each root bridge.

Define the HardwareInfoLib API and create the PeiHardwareInfoLib
which implements it, specifically for Pei usage, supporting
only static accesses to parse data directly from a fw-cfg file.
All list-like APIs are implemented as unsupported and only a
fw-cfg wrapper to read hardware info elements is provided.
The Hardware Info library is intended to describe non-discoverable
hardware information and share that from the host to the guest in Ovmf
platforms. The QEMU fw-cfg extension for this library provides a first
variation to parse hardware info by reading it directly from a fw-cfg
file. This library offers a wrapper function to the plain
QmeuFwCfgReadBytes which, specifically, parses header-data pairs out
of the binary values in the file. For this purpose, the approach is
incremental, reading the file block by block and outputting the values
only for a specific known hardware type (e.g. PCI host bridges). One
element is returned in each call until the end of the file is reached.
Considering fw-cfg as the first means to transport hardware info from
the host to the guest, this wrapping library offers the possibility
to statically, and in steps, read a specific type of hardware info
elements out of the file. This method reads one hardware element of a
specific type at a time, without the need to pre-allocate memory and
read the whole file or dynamically allocate memory for each new
element found.
As a usage example, the static approach followed by this library
enables early UEFI stages to use and read hardware information
supplied by the host. For instance, in early times of the PEI stage,
hardware information can be parsed out from a fw-cfg file prescinding
from memory services, that may not yet be available, and avoiding
dynamic memory allocations.

CcProbeLib is imported in BaseIoLibIntrinsicSev.
OvmfPkg/Library/CcProbeLib is the OvmfPkg version which checks
OvmfWorkArea to return the Cc guest type. It is included
in OvmfPkgX64.dsc and IntelTdx/IntelTdxX64.dsc.
Other .dsc include the MdePkg/Library/CcProbeLibNull because Cc guest
is not supported in those projects.

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
The IOMMU protocol driver provides capabilities to set a DMA access
attribute and methods to allocate, free, map and unmap the DMA memory
for the PCI Bus devices.
The current IoMmuDxe driver supports DMA operations inside SEV guest.
To support DMA operation in TDX guest,
CC_GUEST_IS_XXX (PcdConfidentialComputingGuestAttr) is used to determine
if it is SEV guest or TDX guest.
Due to security reasons all DMA operations inside the SEV/TDX guest must
be performed on shared pages. The IOMMU protocol driver for the SEV/TDX
guest uses a bounce buffer to map guest DMA buffer to shared pages in
order to provide the support for DMA operations inside SEV/TDX guest.
The call of SEV or TDX specific function to set/clear EncMask/SharedBit
is determined by CC_GUEST_IS_XXX (PcdConfidentialComputingGuestAttr).
