The SRAT/HMAT/SLIT tables describe the relations between
ProximityDomain IDs. These proximity domains might represent
memory domains, CPUs, IO, etc.
ProximityDomain IDs are mere IDs. They don't represent anything
and could be generated by the DynamicTablesPkg framework. These
IDs are currently hard-coded by the ConfigurationManager developer.
In order to:
- avoid the developer to keep track of the used ProximityDomain IDs
- have a better internal representation of the relation between
CPUs sharing the same ProximityDomain ID
allow the developer to use Tokens pointing to ProximityDomain
structures.

The ACPI specification v6.5, sTable 5.158: Processor Structure Flags
states that:
"""
The processor container will have a matching ID
value returned through the _UID method. As not every pro-
cessor hierarchy node structure in PPTT may have a matching
processor container, this flag indicates whether the ACPI pro-
cessor ID points to valid entry. Where a valid entry is possible
the ACPI Processor ID and _UID method are mandatory.
"""
And in:
Table 5.157: Processor Hierarchy Node Structure
"""
If the processor structure rep-
resents a group of associated processors, the structure might
match a processor container in the name space. In that case
this entry will match the value of the _UID method of the as-
sociated processor container. Where there is a match it must
be represented. The flags field, described in Processor Struc-
ture Flags, includes a bit to describe whether the ACPI pro-
cessor ID is valid.
"""
The DynamicTablesPkg currently creates a processor container:
- in the SSDT CPU Topology generator, with the _HID=ACPI0010,
and with a valid _UID
- in the PPTT table
for each CM_ARCH_COMMON_PROC_HIERARCHY_INFO structure.
Thus:
- all the processor containers should have the VALID bit set
if the SSDT CPU Topology table is present.
- if the SSDT CPU Topology table is present, but there is no
PPTT table, then the state of the VALID bit is ignored.
A contrario, an example where the VALID bit should not be set
would be if:
- the SSDT CPU Topology generator is absent
- no processor container is created in the SSDT topology,
i.e. if a flat hierarchy is created.

Some generators share some logic in how they handle CmObj.
In an effort to factorize this code, create a CmObjHelperLib,
aiming to host the common CmObj manipulation logic.

to check if an ACPI table is in the list of the tables to

The newly added MetadataObjLib allows to store information either:
- generated by the DynamictTablesPkg framework
- provided by a ConfigurationManager
- parsed from another source of information
This information might be subject to validation/verification.
This step can only be done once the firmware tables generated
by the DynamictTablesPkg have been generated.
Add a new GetMetadataRoot() callback to the
EDKII_DYNAMIC_TABLE_FACTORY_PROTOCOL. This callback allows
to fetch the Metadata Root, allowing to access all the Metadata
information generated. This Metadata is then validated by the
DynamicTableManagerDxe.

Built on top of the MetadataObjLib, this library aims to
provide functions for each METADATA_ID to:
- Generate new Metadata on the fly: the caller provides
minimal information for a METADATA_ID, and the library
generates the missing information.
- Validate all the Metadata objects for a METADATA_ID.
For instance, _UID must be unique for a _HID/_CID/EISAID.
This patch also adds support for generation/validation of:
- UIDs:
For each EISAID or NameId, UIDs must be unique. The generation
if UIDs is done by a per-EISAID/NameId incrementing counter.
The validation of the Metadata consists in checking for the
uniqueness of the UID per EISAID/NameId.
- ProximityDomains:
Proximity Domain Ids are generated by a counter, starting
from 0.
The validation of the Metadata consists in checking for
the uniqueness of the proximity domain Ids.

The DynamicTablesPkg allows to generate firmware tables based on
information provided by a user or another source of information
(a device tree for instance).
Some information might be implicitly generated by generators.
For instance, for ACPI tables, AML names or Uids are created by
generators, but not provided by the user or another source of
information.
Some generators might need to cross-reference object/generated data
that was previous generated for an object by another generator.
For instance, there are three different generators creating serial
ports in the AML namespace. These 3 generators must ensure not to use
an Id which was not already created by another generator.
Another example would be a generator needing to reference the AML
path of a serial port. As the AML path is dynamically generated, this
is currently not possible to do.
Add a MetaDataObjLib library to keep track of the meta-data previously
generated for an object.

Additionally, the spec documents EFI_ACCESS_DENIED for gBS->LoadImage() as

Adds support for building the C language BaseTools for Windows using
toolchains based on mingw-w64.
Mingw-w64 is a collection of header files, libraries, and tools that
when combined with a compiler enable development of Windows software.
Mingw-w64 is a fork of the original MinGW (Minimalist GNU for Windows).
Most active development on MinGW has ceased and mingw-w64 is now the
actively maintained successor. Mingw-w64 provides a libc implementation
built on top of Microsoft's UCRT (Universal C Runtime) with all
nessesary compiler bindings needed to support the C++11 feature set.
Modern mingw-w64 development appears to have coalesced around MSYS2,
which produces a distributions of both GCC and LLVM/Clang that use
mingw-w64 to target the Windows OS. This MSYS2 Clang distribution has a
UNIX-like directory layout and includes Windows binaries of GNU Make.
Combined with the open source licensing, MSYS2's Clang distribution is a
highly attractive choice as an alternative Windows SDK for open source
projects such as TianoCore.
If one wishes to use EDK II to build UEFI firmware on the Windows
platform, then the C BaseTools need to be compiled as Windows
applications. This includes the PcdValueInit.exe program, which needs
to be recompiled every time a firmware build is run in order to
regenerate the initial values for structured PCDs. Currently, BaseTools
only supports the Visual C++ toolchain on the Windows platform. The
following new features have been added to enable usage of the toolchains
derived from mingw-w64:
- Fixes to the BaseTools C source code to support the use of a
GCC-style compiler on the Windows OS.
- The GNU Make-style Makefiles for the C BaseTools have been modified
to support Windows. Both GCC + mingw-w64 and Clang + mingw-w64 have
been tested and confirmed to build a working BaseTools.
- BaseTools now supports generating GNU Make-style Makefiles on the
Windows platform for the purpose of building firmware.
- edksetup.bat has been modified to optionally build BaseTools via
mingw-w64. There is no impact to the existing support for Visual C++
and Visual C++ remains the default toolchain.
Usage Instructions:
For the vast majority of users, the only system setup change nessesary
to use a mingw-w64 toolchain is to set the BASETOOLS_MINGW_PATH to the
directory containing the desired mingw-w64 based toolchain.
A new command line argument has been added to edksetup.bat: Mingw-w64
If this command line argument is set, then the script will set the
BASETOOLS_MINGW_BUILD environment variable. The user can also opt to set
this environment variable manually before running edksetup.bat
If BASETOOLS_MINGW_BUILD is defined, then the BASETOOLS_MINGW_PATH
environment variable must point to the directory containing the
mingw-w64 toolchain.
If CLANG_BIN is not defined and %BASETOOLS_MINGW_PATH%\bin\clang.exe
exists, then edksetup.bat will set CLANG_BIN=%BASETOOLS_MINGW_PATH%\bin\
This removes the requirement to configure the CLANG_BIN environment
variable manually in order to run a CLANGPDB or CLANGDWARF build if one
has the MSYS2 Clang distribution installed. If one wishes to use a
different copy of Clang (for example official LLVM binaries) to build
firmware and only use the MSYS2 Clang to build BaseTools, then one can
continue to set the CLANG_BIN environment variable, same as before. I
have tested the MSYS2 Clang distribution against the official LLVM
distribution and can confirm that if the compiler version is the same
the emitted machine code is identical between the two. Interestingly,
the MSYS2 Clang distribution emits the path to the PDB file using "/" as
the path seperator instead of "\". That appears to be the only
difference in output. Therefore, using the MSYS2 Clang distribution to
compile firmware seems a reasonable choice.
If CLANG_HOST_BIN is not defined and BASETOOLS_MINGW_BUILD is defined
and %BASETOOLS_MINGW_PATH%\bin\mingw32-make.exe exists, then
edksetup.bat will add %BASETOOLS_MINGW_PATH%\bin\ to the PATH and set
CLANG_HOST_BIN=mingw32-
This enable usage of the GNU Make included in the mingw-w64 toolchain
to build firmware in addition to BaseTools. if BASETOOLS_MINGW_BUILD is
not defined, edksetup.bat will continue to set CLANG_HOST_BIN=n, which
uses nmake to build firmware. This behavior can be overridden by
manually setting the value of CLANG_HOST_BIN before executing
edksetup.bat if one wishes to use a specific Make utility for the
CLANGPDB/CLANGDWARF toolchains.

Fixes a BaseTools Bin directory path detection bug in the the BaseTools
Unit Tests. The script incorrectly assumes that sys.platform

The "win64" platform string has not been used for 64-bit Python
interperters since May 10, 2000:
https://github.com/python/cpython/commit/da5cc82d
Moreover, this patch was merged before the Python 2.0 release, so there
never has been a released Python interperter that used the "win64"
string.

This commit enables extended SPI support for GicV3. GicV3 must decide,
based on the source intid, whether to access the SPI-range registers,
PPI-range registers in the redistributor, or the extended SPI-range
registers.
The protocol interfaces must also support registering an interrupt
handler with an extended SPI intid. To save ~24KB of memory, handler
allocation and access is delegated to GicV2 and GicV3. GicV2 retains the
existing handler mapping scheme using intids literally. GicV3 remaps
extended SPI intids to be immediately after the highest SPI intids.

Align HTTP Boot behavior with PXE by inserting a delay to wait for IPv6 Duplicate Address Detection (DAD) to complete before issuing DHCPv6 requests. This avoids EFI_NO_MAPPING errors caused by early DHCP attempts before a valid IPv6 address is ready.
Problem:
On some platforms, HTTP boot over IPv6 fails with EFI_NO_MAPPING during initial DHCPv6 attempts. The failure is due to the system trying to send Solicit messages before IPv6 DAD finishes, resulting in no usable IP address at that time.
Solution:
Insert a retry mechanism to poll DAD completion when the initial call to Dhcp6->Start() fails with EFI_NO_MAPPING. This behavior mirrors PXE's handling, where it waits for a valid IPv6 address to be assigned before retrying the DHCPv6 flow.

When booting under Xen/Arm64 with a flattened devicetree, XenioFdtDxe.c
performs a runtime assert on the size of the hypervisor node. At some
point the hypervisor devicetree node changed size in upstream Xen, which
makes booting under Xen impossible because the assertion fails:
ASSERT [XenioFdtDxe] XenioFdtDxe.c(64): RegSize == 2 * sizeof (UINT64)
By putting a debug print in InitializeXenioFdtDxe we can see the value
of RegSize is 48, instead of 2 * sizeof (UINT64)=16.
