The SetMemoryEncDec() is used by the higher level routines to set or clear
the page encryption mask for system RAM and Mmio address. When SEV-SNP is
active, in addition to set/clear page mask it also updates the RMP table.
The RMP table updates are required for the system RAM address and not
the Mmio address.
Add a new parameter in SetMemoryEncDec() to tell whether the specified
address is Mmio. If its Mmio then skip the page state change in the RMP
table.

The initial page built during the SEC phase is used by the
MemEncryptSevSnpValidateSystemRam() for the system RAM validation. The
page validation process requires using the PVALIDATE instruction; the
instruction accepts a virtual address of the memory region that needs
to be validated. If hardware encounters a page table walk failure (due
to page-not-present) then it raises #GP.
The initial page table built in SEC phase address up to 4GB. Add an
internal function to extend the page table to cover > 4GB. The function
builds 1GB entries in the page table for access > 4GB. This will provide
the support to call PVALIDATE instruction for the virtual address >
4GB in PEI phase.

Virtual Machine Privilege Level (VMPL) feature in the SEV-SNP
architecture allows a guest VM to divide its address space into four
levels. The level can be used to provide the hardware isolated
abstraction layers with a VM. The VMPL0 is the highest privilege, and
VMPL3 is the least privilege. Certain operations must be done by the
VMPL0 software, such as:
* Validate or invalidate memory range (PVALIDATE instruction)
* Allocate VMSA page (RMPADJUST instruction when VMSA=1)
The initial SEV-SNP support assumes that the guest is running on VMPL0.
Let's add function in the MemEncryptSevLib that can be used for checking
whether guest is booted under the VMPL0.

Many of the integrity guarantees of SEV-SNP are enforced through the
Reverse Map Table (RMP). Each RMP entry contains the GPA at which a
particular page of DRAM should be mapped. The guest can request the
hypervisor to add pages in the RMP table via the Page State Change VMGEXIT
defined in the GHCB specification section 2.5.1 and 4.1.6. Inside each RMP
entry is a Validated flag; this flag is automatically cleared to 0 by the
CPU hardware when a new RMP entry is created for a guest. Each VM page
can be either validated or invalidated, as indicated by the Validated
flag in the RMP entry. Memory access to a private page that is not
validated generates a #VC. A VM can use the PVALIDATE instruction to
validate the private page before using it.
During the guest creation, the boot ROM memory is pre-validated by the
AMD-SEV firmware. The MemEncryptSevSnpValidateSystemRam() can be called
during the SEC and PEI phase to validate the detected system RAM.
One of the fields in the Page State Change NAE is the RMP page size. The
page size input parameter indicates that either a 4KB or 2MB page should
be used while adding the RMP entry. During the validation, when possible,
the MemEncryptSevSnpValidateSystemRam() will use the 2MB entry. A
hypervisor backing the memory may choose to use the different page size
in the RMP entry. In those cases, the PVALIDATE instruction should return
SIZEMISMATCH. If a SIZEMISMATCH is detected, then validate all 512-pages
constituting a 2MB region.
Upon completion, the PVALIDATE instruction sets the rFLAGS.CF to 0 if
instruction changed the RMP entry and to 1 if the instruction did not
change the RMP entry. The rFlags.CF will be 1 only when a memory region
is already validated. We should not double validate a memory
as it could lead to a security compromise. If double validation is
detected, terminate the boot.

SEV-SNP firmware allows a special guest page to be populated with
guest CPUID values so that they can be validated against supported
host features before being loaded into encrypted guest memory to be
used instead of hypervisor-provided values [1].
Add handling for this in the CPUID #VC handler and use it whenever
SEV-SNP is enabled. To do so, existing CPUID handling via VmgExit is
moved to a helper, GetCpuidHyp(), and a new helper that uses the CPUID
page to do the lookup, GetCpuidFw(), is used instead when SNP is
enabled. For cases where SNP CPUID lookups still rely on fetching
specific CPUID fields from hypervisor, GetCpuidHyp() is used there as
well.

Remove the QemuFwCfgLib interface used to read the QEMU cmdline
(-append argument) and the initrd size. Instead, use the synthetic
filesystem QemuKernelLoaderFs which has three files: "kernel", "initrd",
and "cmdline".

When QemuLoadKernelImage() ends successfully, the command-line blob is
not freed, even though it is not used elsewhere (its content is already
copied to KernelLoadedImage->LoadOptions). The memory leak bug was
introduced in commit 7c47d89003 ("OvmfPkg: implement QEMU loader

The "OvmfPkg/Library/PciHostBridgeLibScan/PciHostBridgeLibScan.inf"
instance is used in the following platforms in edk2:
OvmfPkg/Bhyve/BhyveX64.dsc
OvmfPkg/OvmfXen.dsc
Neither Bhyve nor Xen provide a Q35 board, therefore the expression
PcdGet16 (PcdOvmfHostBridgePciDevId) != INTEL_Q35_MCH_DEVICE_ID
always evaluates to TRUE, in the PciHostBridgeLibScan instance.
Replace the expression with constant TRUE, eliminating the PCD dependency.
(In effect, this reports that the root bridge being registered does not
support extended PCI config space.)

instance is used in the following platforms in edk2:
OvmfPkg/Bhyve/BhyveX64.dsc
OvmfPkg/OvmfXen.dsc
Both platforms define "PcdPciDisableBusEnumeration" with Fixed-at-Build
access method, and TRUE value. Remove the PCD from the
PciHostBridgeLibScan instance, and everything else that is useful only
when the PCD is FALSE.
In practice, this removes the PciHostBridgeUtilityGetRootBridges()
function call, which is based on fw-cfg; see
"OvmfPkg/Library/PciHostBridgeUtilityLib/PciHostBridgeUtilityLib.c".
(Note that the dependency on PciHostBridgeUtilityLib remains in place,
given that the PciHostBridgeLibScan instance continues using lower-level
functions from the library that do not depend on fw-cfg.)

All these platforms statically inherit PcdPciDisableBusEnumeration=FALSE
from "MdeModulePkg.dec". Remove the the PCD and everything that depends on
it from the PciHostBridgeLib instance. Namely, remove the logic that
determines the root bridge apertures by (a) scanning the entire bus,
device and function number space, and (b) parsing the BAR values that were
pre-set by the Bhyve or Xen machinery.
"XenSupport.c" used to be listed explicitly in "Maintainers.txt", remove
it from that spot too.

Create an almost verbatim copy of the
"OvmfPkg/Library/PciHostBridgeLib/PciHostBridgeLib.inf" library instance.
The new PciHostBridgeLibScan instance will ultimately duplicate a
negligible amount of code from the original, and will be used by the Bhyve
and OvmfXen platforms.
List the new driver in "Maintainers.txt", in the "OvmfPkg: bhyve-related
modules" and "OvmfPkg: Xen-related modules" sections.
This patch should be reviewed with "git show --find-copies-harder".

an example identifier that's actually consumed.
- Place all public #includes first, all module-private #includes second.
Separate them with a single empty line. Keep each section sorted in
itself.
- Sort all sections in the INF file, except [Defines].
- Add unlisted lib classes.
- Remove unnecessary #include directives, add unlisted #include
directives.
