Ensure that the PixelInformation field of the
EFI_GRAPHICS_OUTPUT_MODE_INFORMATION structure is zeroed out in
EFI_GRAPHICS_OUTPUT_PROTOCOL.QueryMode() and
EFI_GRAPHICS_OUTPUT_PROTOCOL.SetMode() when PixelFormat is
PixelBlueGreenRedReserved8BitPerColor.
According to UEFI 2.9 Section 12.9, PixelInformation field of the
EFI_GRAPHICS_OUTPUT_MODE_INFORMATION structure is valid only if
PixelFormat is PixelBitMask. This means that firmware is not required
to fill out the PixelInformation field for other PixelFormat types,
which implies that the QemuVideoDxe implementation is technically
correct.
However, not zeroing out those fields will leak the contents of the
memory returned by the memory allocator, so it is better to explicitly
set them to zero.
In addition, the SCT test suite relies on PixelInformation always
having a consistent value, which causes failures.

Consume the host-provided specification of PCI host bridges if
available. Using the DxeHardwareInfoLib, populate a list of
hardware descriptors based on the content of the "hardware-info"
fw-cfg file, if provided. In the affirmative case, use the
resources and attributes specified by the hypervisor for each
Host Bridge to create the RootBridge elements.
In Ovmf platforms, the host can provide the specification of
non-discoverable hardware resources like PCI host bridges. If the
proper fw-cfg file is found, parse the contents provided by the
host into a linked list by using the Hardware Info library. Then,
using the list of PCI host bridges' descriptions, populate the
PCI_ROOT_BRIDGES array with the resources and attributes specified
by the host. If the file is not provided or no Host Bridge is found
in it, fold back to the legacy method based on pre-defined
apertures and rules.
In some use cases, the host requires additional control over the
hardware resources' configurations in the guest for performance and
discoverability reasons. For instance, to disclose information about
the PCI hierarchy to the guest so that this can profit from
optimized accesses. In this case, the host can decide to describe
multiple PCI Host Bridges and provide a specific set of resources
(e.g. MMIO apertures) so that the guest uses the values provided.
Using the provided values may entitle the guest to added performance,
for example by using specific MMIO mappings that can enable peer-to-peer
communication across the PCI hierarchy or by allocating memory closer
to a device for faster DMA transactions.

Read the "hardware-info" item from fw-cfg to extract specifications
of PCI host bridges and analyze the 64-bit apertures of them to
find out the highest 64-bit MMIO address required which determines
the address space required by the guest, and, consequently, the
FirstNonAddress used to calculate size of physical addresses.
Using the static PeiHardwareInfoLib, read the fw-cfg file of
hardware information to extract, one by one, all the host
bridges. Find the last 64-bit MMIO address of each host bridge,
using the HardwareInfoPciHostBridgeLib API, and compare it to an
accumulate value to discover the highest address used, which
corresponds to the highest value that must be included in the
guest's physical address space.
Given that platforms with multiple host bridges may provide the PCI
apertures' addresses, the memory detection logic must take into
account that, if the host provided the MMIO windows that can and must
be used, the guest needs to take those values. Therefore, if the
MMIO windows are found in the host-provided fw-cfg file, skip all the
logic calculating the physical address size and just use the value
provided. Since each PCI host bridge corresponds to an element in
the information provided by the host, each of these must be analyzed
looking for the highest address used.

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.

Create the Hardware Info library base together with the specifics to
describe PCI Host Bridges.
The Hardware Info library is intended to be used for disclosing
non-discoverable hardware information from the host to the guest in
Ovmf platforms. Core functionality will provide the possibility to
parse information from a generic BLOB into runtime structures. The
library is conceived in a generic way so that further hardware
elements can also be described using it. For such purpose the length
of the BLOB is not restricted but instead regarded as a sequence of
header-info elements that allow the parsing during runtime. The first
type of hardware defined will be PCI host bridges, providing the
possibility to define multiple and specify the resources each of them
can use. This enables the guest firmware to configure PCI resources
properly. Having the size of each individual element favors the reuse
of a single interface to convey descriptions of an arbitrary number
of heterogenous hardware elements. Furthermore, flexible access
mechanisms coupled with the size will grant the possibility of
interpreting them in a single run.
Define the base types of the generic Hardware Info library to parse
heterogeneous data. Also provide the specific changes to support
PCI host bridges as the first hardware type supported by the
library.
Additionally, define the HOST_BRIDGE_INFO structure to describe PCI
host bridges along with the functionality to parse such information
into proper structures used by the PCI driver in a centralized manner
and taking care of versioning.
As an example and motivation, the library will be used to define
multiple PCI host bridges for complex platforms that require it.
The first means of transportation that will be used is going to be
fw-cfg, over which a stream of bytes will be transferred and later
parsed by the hardware info library. Accordingly, the PCI driver
will make use of these host bridges definitions to populate the
list of Root Bridges and proceed with the configuration and discovery
of underlying hardware components.
As mentioned before, the binary data to be parsed by the Hardware
Info library should be organized as a sequence of Header-element
pairs in which the header describes the type and size of the associated
element that comes right after it. As an illustration, to provide
inforation of 3 host bridges the data, conceptually, would look
like this:
Header PCI Host Bridge (type and size) # 1
PCI Host Bridge info # 1
Header PCI Host Bridge (type and size) # 2
PCI Host Bridge info # 2
Header PCI Host Bridge (type and size) # 3
PCI Host Bridge info # 3

The ebp/rbp register can either be used for the frame pointer or
as general purpose register. With gcc (and clang) this depends
on the -f(no-)omit-frame-pointer switch.
This patch updates tools_def.template to explicitly set the compiler
option and also add a define to allow conditionally compile code.
The new define is used to fix stack switching in TemporaryRamMigration.
The ebp/rbp must not be touched when the compiler can use it as general
purpose register. With version 12 gcc starts actually using the
register, so changing it leads to firmware crashes in some
configurations.

In current TDVF implementation all unaccepted memory passed in Hoblist
are tagged as EFI_RESOURCE_MEMORY_UNACCEPTED. They're all accepted before
they can be accessed. After accepting memory region, the Hob ResourceType
is unchanged (still be EFI_RESOURCE_MEMORY_UNACCEPTED).
TDVF Config-B skip PEI phase and it tries to find a memory region which
is the largest one below 4GB. Then this memory region will be used as the
firmware hoblist.
So we should walk thru the input hoblist and search for the memory region
with the type of EFI_RESOURCE_MEMORY_UNACCEPTED.
Because EFI_RESOURCE_MEMORY_UNACCEPTED has not been officially in PI spec.
So it cannot be defined in MdePkg/Include/Pi/PiHob.h. As a temporary
solution it is defined in Hob.c.
There is a patch-set for lazy-accept very soon. In that patch-set
EFI_RESOURCE_MEMORY_UNACCEPTED will be defined in MdeModulePkg.

the SEV_STATUS MSR Bit 1 to determine if SEV-ES is enabled. This check
was not part of the original SEV-ES support and was added in
a91b700e38. Removing the check makes this code consistent with the
Linux kernel

In TDX, Application Processor busy-loops on Mailbox for OS to issue
MpProtectedModeWakeupCommandWakeup command to UEFI. As the AP acking to
it, it clears the command member according to ACPI spec 6.4, 5.2.12.19
Multiprocessor Wakeup Structure: "The application processor need clear the
command to Noop(0) as the acknowledgement that the command is received."
However, AsmRelocateApMailBoxLoop wrongly clears WakeupVector. Correctly
clear command instead of WakeupVector.
Without this patch, TD guest kernel fails to boot APs.

The BaseMemEncryptSevLib functionality was updated to rely on the use of
the OVMF/SEV workarea to check for SEV guests. However, this area is only
updated when running the X64 OVMF build, not the hybrid Ia32/X64 build.
Base SEV support is allowed under the Ia32/X64 build, but it now fails
to boot as a result of the change.
Update the ResetVector code to check for SEV features when built for
32-bit mode, not just 64-bit mode (requiring updates to both the Ia32
and Ia32X64 fdf files).

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3930
CcProbeLib is designed to check the vm guest type. The OvmfPkg/CcProbeLib
reads the OvmfWorkArea (0x80B000) to get the vm guest type which is
written by each guest (SEV or TDX guest). But in SMM drivers the access
to OvmfWorkArea is illegal. PiSmmCpuDxeSmm.inf is an example. It uses
IoLib which in OvmfPkgX64 BaseIoLibIntrinsicSev.inf is included. The
IoLib probes if the working guest is td guest by calling CcProbe().
So CcProbeLibNull will be included when SMM_REQUIRE is set. Currently
only TDVF uses CcProbe to check the guest type, and TDVF doesn't
support SMM, so this fix has no side-effect.

In OvmfPkgX64 we enable 2 different CpuMpPei and CpuDxe drivers. The
difference between the drivers is the MpInitLib or MpInitLibUp. This is
acomplished by adding a MpInitLibDepLib.
In IntelTdxX64 we enable 2 versions of CpuDxe drivers. It is because PEI
is skipped in IntelTdxX64.
