GCC -fno-builtin option is added into tools_def.template at
90defe7198a42b3157ae5d9b93714f891cf06e57.
So, there is no need to set it in module INF file.

Old implementation only finds first matched full device path for a
given short-form device path.
The patch adds internal function BmGetNextLoadOptionBuffer() to finds
all matched full device path for a given short-form device path.
There are 6 kinds of device paths. Some of them match to multiple
load options, some of them don't.
1. Media device path:
Returns multiple load options: The media device path may point
to a physical BlockIo which contains multiple logic partitions,
each logic partitions contains \EFI\BOOT\BOOT${ARCH}.EFI.
2. Short-form hard-drive device path:
Returns one load option because the partition signature is unique.
3. Short-form file-path device path:
Returns multiple load options: There are multiple SimpleFileSystem
instances and each contains the same file.
4. Short-form URI device path:
Returns multiple load options: There are multiple LoadFile
instances and each can boot.
5. Short-form USB device path:
Returns multiple load options: There are multiple UsbIo instances
and each contains the boot-able file.
6. FV device path, device path pointing to SimpleFileSystem, device
path pointing to LoadFile
Returns one load option.

The EFI_IMAGE_MACHINE_TYPE_SUPPORTED() macro is abused in the PeiCore
code to decide whether the system we are compiling for can deal with
executable code being copied elsewhere and executed from there.
As stated in the comment, this is fundamentally a property of the compiler
target, and so this should be made dependent on MDE_CPU_xxx preprocessor
defines, and not on whether or not the runtime target can deal with
PE/COFF images of a certain machine type.
On X86/IA32, this mostly boils down to the same thing, but not on other
architectures, so let's clean this up.

Currently, the PE/COFF image memory protection code uses the same code
paths for protecting and unprotecting an image. This is strange, since
unprotecting an image involves a single call into the CPU arch protocol
to clear the permission attributes of the entire range, and there is no
need to parse the PE/COFF headers again.
So let's store the ImageRecord entries in a linked list, so we can find
it again at unprotect time, and simply clear the permissions.
Note that this fixes a DEBUG hang on an ASSERT() that occurs when the
PE/COFF image fails to load, which causes UnprotectUefiImage() to be
invoked before the image is fully loaded.

The BGRT table has an 8 byte field for the memory address of the image
data, and yet the driver explicitly allocates below 4 GB. This results
in an ASSERT() on systems that do not have any memory below 4 GB to begin
with.
Since neither the PI, the UEFI or the ACPI spec contain any mention of
why this data should reside below 4 GB, replace the allocation call
with an ordinary AllocatePages() call.

Invocations of EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() may
result in a crash when the value of PcdAcpiExposedTableVersions does
not include EFI_ACPI_TABLE_VERSION_1_0B.
The reason is that EFI_ACPI_TABLE_PROTOCOL::InstallAcpiTable() will
only populate the Rsdt1/Rsdt3 pointers when EFI_ACPI_TABLE_VERSION_1_0B
is set, whereas EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() will
invoke PublishTables with EFI_ACPI_TABLE_VERSION_1_0B alawys set,
resulting in a NULL pointer dereference of the Rsdt1/Rsdt3 pointers.
So take PcdAcpiExposedTableVersions into account for UninstallAcpiTable
as well.

function. If EFI_ACPI_TABLE_PROTOCOL and/or EFI_ACPI_SDT_PROTOCOL are not

The logic is fine, but the info messages are not concatenated correctly

When attempting to perform page allocations using AllocateAddress, we
fail to check whether the entire region is free before splitting the
region. This may lead to memory being leaked further into the routine,
when it turns out that one of the memory map entries intersected by the
region is already occupied. In this case, prior conversions are not rolled
back.
For instance, starting from this situation
0x000040000000-0x00004007ffff [ConventionalMemory ]
0x000040080000-0x00004009ffff [Boot Data ]
0x0000400a0000-0x000047ffffff [ConventionalMemory ]
a failed EfiLoaderData allocation @ 0x40000000 that covers the BootData
region will fail, but leave the first part of the allocation converted,
so we end up with
0x000040000000-0x00004007ffff [Loader Data ]
0x000040080000-0x00004009ffff [Boot Data ]
0x0000400a0000-0x000047ffffff [ConventionalMemory ]
even though the AllocatePages() call returned an error.
So let's check beforehand that AllocateAddress allocations are covered
by a single memory map entry, so that it either succeeds or fails
completely, rather than leaking allocations.

The original logic assumes GOP hande is son of PCI handle but it
is not always true.
Below wordings are from UEFI Spec:
If a graphics device supports multiple frame buffers, then
handles for the frame buffers must be created first, and then the
handles for the video output devices can be created as children of
the frame buffer handles.
So the GOP handle could be grandson of the PCI handle.

v2: Handle error case in SockCreateChild and fix typo issue
when we destroy the socket Sock and its associated
protocol control block, we need to first close the
parent protocol, then remove the protocol from childHandle
and last to free any data structures that allocated in
CreateChild. But currently, we free the socket data
(Socket ConfigureState) before removing the protocol
form the childhandle. So if the up layer want to send the
tcp reset packet in it's driver binding stop function, it will failed.
The IpInstance destroy state is redundant and may cause
ip transmit failed if up layer want to send ip packet.

The ACPI specification, up to and including revision 5.1 Errata A, allows
the DSDT and X_DSDT fields to be both set in the FADT. (Obviously, this
only makes sense if the DSDT address is representable in 4 bytes.)
Starting with 5.1 Errata B, specifically for Mantis 1393
<https://mantis.uefi.org/mantis/view.php?id=1393>, the spec requires at
most one of DSDT and X_DSDT to be set to a nonzero value.
MdeModulePkg/AcpiTableDxe handles this mutual exclusion somewhat
inconsistently.
- If the caller of EFI_ACPI_TABLE_PROTOCOL.InstallAcpiTable() installs the
tables in "DSDT, FADT" order, then we enforce the exclusion between the
DSDT and X_DSDT fields:
DSDT under 4GB FADT.DSDT FADT.X_DSDT [VARIANT B]
-------------- --------- -----------
yes set clear
no clear set
This behavior conforms to 5.1 Errata B. (And it's not required by
earlier versions of the spec.)
- If the caller passes in the tables in "FADT, DSDT" relative order, then
we do not enforce the exclusion:
DSDT under 4GB FADT.DSDT FADT.X_DSDT [VARIANT A]
-------------- --------- -----------
yes set set
no clear set
This satisfies 5.1 Errata A and earlier, but breaks 5.1 Errata B and
later.
Unify the handling of both relative orders. In particular, check the major
and minor version numbers in the FADT. If the FADT version is strictly
before 5.1, then implement [VARIANT A]. If the FADT version is equal to or
larger than 5.1, then implement [VARIANT B].
We make three observations:
- We can't check the FADT table version precisely against "5.1 Errata B";
erratum levels are not captured in the table. We err in the safe
direction, namely we enforce the exclusion for "5.1" and "5.1 Errata A".
- The same applies to "6.0" versus "6.0 Errata A". Because we cannot
distinguish these two, we consider "6.0" to be "equal to or larger than
5.1", and apply [VARIANT B], enforcing the exclusion.
- While a blanket [VARIANT B] would be simpler, there is a significant
benefit to [VARIANT A], under the spec versions that permit it:
compatibility with a wider range of OSPMs (typically, older ones).
For example, Igor reported about a "DELL R430 system with rev4 FADT
where DSDT and X_DSDT are pointing to the same address". Michael also
reported about several systems that exhibit the same.
Regression tested with the following KVM guests (QEMU built at

- Windows 7
- Windows 8.1
- Windows 10
- Windows Server 2008 R2
- Windows Server 2012 R2
- Windows Server 2016 Tech Preview 4
- X64, I440FX, no SMM
- Fedora 24
- RHEL-6.7
- RHEL-7.2-ish
- ArmVirtQemu: boot test with virtio-gpu
- AARCH64
- Fedora 24

This patch incurs no functional changes, it just removes some whitespace,
and also makes sure we always assign
AcpiTableInstance->Fadt3->Dsdt
first, and
AcpiTableInstance->Fadt3->XDsdt
second. The goal is to separate the syntactic changes from the functional
changes implemented by the next patch.

Architectures such as AArch64 may run the OS with 16 KB or 64 KB sized
pages, and for this reason, the UEFI spec mandates a minimal allocation
granularity of 64 KB for regions that may require different memory
attributes at OS runtime.
So make PeiCore's implementation of AllocatePages () take this into
account as well.
