Li, Zhihao 8079d4dc4f MdePkg: add SmmCpuRendezvousLib.h and SmmCpuRendezvousLibNull implement.
REF? https://bugzilla.tianocore.org/show_bug.cgi?id=3912

UefiCpuPkg define a new Protocol with the new services
SmmWaitForAllProcessor(), which can be used by SMI handler
to optionally wait for other APs to complete SMM rendezvous in
relaxed AP mode.

VariableSmm and VariableStandaloneMM driver in MdeModulePkg need
to use this services but MdeModulePkg can't depend on UefiCpuPkg.

Thus, the solution is moving SmmCpuRendezvouslib.h from UefiCpuPkg
to MdePkg and creating SmmCpuRendezvousLib NullLib version
implementation in MdePkg as dependency for the pkg that can't
depend on UefiCpuPkg.

Min Xu 7012cb73c4 MdePkg: Probe Cc guest in BaseIoLibIntrinsicSev
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902

Bad IO performance in SEC phase is observed after TDX features was
introduced. (after commit b6b2de8848 - "MdePkg: Support mmio for
Tdx guest in BaseIoLibIntrinsic").

This is because IsTdxGuest() will be called in each MMIO operation.
It is trying to cache the result of the probe in the efi data segment.
However, that doesn't work in SEC, because the data segment is read only
(so the write seems to succeed but a read will always return the
original value), leading to us calling TdIsEnabled() check for every
mmio we do, which is causing the slowdown because it's very expensive.

This patch is to call CcProbe instead of TdIsEnabled in IsTdxGuest.
Null instance of CcProbe always returns CCGuestTypeNonEncrypted. Its
OvmfPkg version returns the guest type in Ovmf work area.

Min Xu b6b2de8848 MdePkg: Support mmio for Tdx guest in BaseIoLibIntrinsic
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

TDVF access MMIO with TDG.VP.VMCALL to invoke VMM provided emulation
functions. If the access to MMIO fails, it fall backs to the direct
access.

BaseIoLibIntrinsic.inf is the IoLib used by other packages. It will
not support I/O in Td guest. But some files are shared between
BaseIoLibIntrinsic and BaseIoLibIntrinsicSev (IoLib.c is the example). So
IoLibInternalTdxNull.c (which holds the null stub of the Td I/O routines)
is included in BaseIoLibIntrinsic.inf. BaseIoLibIntrinsic.inf doesn't
import TdxLib so that the Pkgs which include BaseIoLibIntrinsic.inf
need not include TdxLib.

Min Xu ab9d790901 MdePkg: Add helper functions for Tdx guest in BaseIoLibIntrinsic
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

Intel TDX architecture does not prescribe a specific software convention
to perform I/O from the guest TD. Guest TD providers have many choices to
provide I/O to the guest. The common I/O models are emulated devices,
para-virtualized devices, SRIOV devices and Direct Device assignments.

TDVF chooses para-virtualized I/O (Choice-A) which use the TDG.VP.VMCALL
function to invoke the funtions provided by the host VMM to perform I/O.
Another choice (Choice-B) is the emulation performed by the #VE handler.

There are 2 benefits of para-virtualized I/O:
1. Performance.
   VMEXIT/VMENTRY is skipped so that the performance is better than #VE
   handler.
2. De-couple with #VE handler.
   Choice-B depends on the #VE handler which means I/O is not available
   until #VE handler is installed. For example, in PEI phase #VE handler
   is installed in CpuMpPei, while communication with Qemu (via I/O port)
   happen earlier than it.

IoLibInternalTdx.c provides the helper functions for Tdx guest.
IoLibInternalTdxNull.c provides the null version of the helper functions.
It is included in the Non-X64 IoLib so that the build will not be broken.

Ankur Arora 4bf2a5b045 MdePkg: use CpuPause() in CpuDeadLoop()
CpuPause() might allow the CPU to go into a lower power state
state while we spin.

On X86, CpuPause() executes a PAUSE instruction which the Intel
and AMD specs describe as follows:

Intel:
  "PAUSE: An additional function of the PAUSE instruction is to reduce
  the power consumed by a processor while executing a spin loop. A
  processor can execute a spin-wait loop extremely quickly, causing the
  processor to consume a lot of power while it waits for the resource it
  is spinning on to become available. Inserting a pause instruction in a
  spin-wait loop greatly reduces the processor?s power consumption."

AMD:
  "PAUSE: Improves the performance of spin loops, by providing a hint to
  the processor that the current code is in a spin loop. The processor
  may use this to optimize power consumption while in the spin loop.
  Architecturally, this instruction behaves like a NOP instruction."

On RISC-V and ARM64, CpuPause() executes a NOP, which is no worse than
the tight loop we have.

Kun Qin 7cda5d9e3a MdePkg: MmUnblockMemoryLib: Added definition and null instance
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3168

This interface provides an abstration layer to allow MM modules to access
requested areas that are outside of MMRAM. On MM model that blocks all
non-MMRAM accesses, areas requested through this API will be mapped or
unblocked for accessibility inside MM environment.

For MM modules that need to access regions outside of MMRAMs, the agents
that set up these regions are responsible for invoking this API in order
for these memory areas to be accessible from inside MM.

Example usages:
1. To enable runtime cache feature for variable service, Variable MM
module will need to access the allocated runtime buffer. Thus the agent
sets up these buffers, VariableSmmRuntimeDxe, will need to invoke this
API to make these regions accessible by Variable MM.
2. For TPM ACPI table to communicate to physical presence handler, the
corresponding NVS region has to be accessible from inside MM. Once the
NVS region are assigned, it needs to be unblocked thourgh this API.

Compostella, Jeremy d25fd8710d BaseMemoryLibSse2: Take advantage of write combining buffers
The current SSE2 implementation of the ZeroMem(), SetMem(),
SetMem16(), SetMem32 and SetMem64 functions is writing 16 bytes per 16
bytes. It hurts the performances so bad that this is even slower than
a simple 'rep stos' (4% slower) in regular DRAM.

To take full advantages of the 'movntdq' instruction it is better to
"queue" a total of 64 bytes in the write combining buffers.  This
patch implement such a change.  Below is a table where I measured
(with 'rdtsc') the time to write an entire 100MB RAM buffer. These
functions operate almost two times faster.

IA32, since "vmmcall" is not supported in NASM 32-bit mode and VMGEXIT

by the machine mode (M-Mode)timer interrupt redirection. The SRET
instruction clear Supervisor Previous Privilege (SPP) to zero

spec. Above brings hart to the user mode (U-Mode) when execute
SRET in the nested S-Mode interrupt handler because SPP is set to
User Mode in the second interrupt. Afterward, system runs in U-Mode
and any accesses to S-Mode CSR causes the invalid instruction exception.

Michael D Kinney 9a6c4ac68e MdePkg/Library/BaseStackCheckLib: Fix PCD type in INF
Update INF file to use a [Pcd] section instead of a
[FixedPcd] section.  [FixedPcd] should only be used in an
INF file if the source code looks up the PCD value using
the PcdLib FixedPcdGetxx() services.  Using [FixedPcd]
forces a platform to configure the PCD to type FixedAtBuild.
In this case, PcdDebugPropertyMask supports PCD types
FixedAtBuild and PatchableInModule.  Without this change
any platform that wants to use PcdDebugPropertyMask as
type PatchableInModule breaks the build.

Michael D Kinney 540fd45f75 MdePkg/Library/BaseLib: Add BaseLib instance for host based unit tests
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2800

Add a new version of BaseLib that is safe for use from host based
unit test applications.  Host based unit test applications may need
to provide implementations of some BaseLib functions that provide
simple emulation to exercise the code under test.  The structure
UNIT_TEST_HOST_BASE_LIB is filled in with services that provide
default emulation for BaseLib APIs that would normally generate
exceptions in a host based unit test application.  This structure
allows an individual unit test to replace the default emulation of
a BaseLib service with an alternate version that is required by a
specific unit test.  A global variable of type UNIT_TEST_HOST_BASE_LIB
is provided through the new UnitTestHostBaseLib library class.

Normally cmocka would be used to mock services the code under
test calls.  However, the BaseLib is used by the Unit Test
Framework itself, so using a mocked interface is not possible.
The use of a structure to provide hooks for unit test is not
expected to be a common feature.  It should only be required
for libraries that are used by both the Unit Test Framework and
the code under test where the code under test requires a
different behavior than the Unit Test Framework.

Ard Biesheuvel a2433243fb MdePkg/BasePrintLib: avoid absolute addresses for error strings
The mStatusString[] array is constructed as an array of pointer-to-char,
which means that on X64 or AARCH64, it is emitted as a single linear list
of 64-bit quantities, each containing the absolute address of one of the
string literals in memory.

This means that each string takes up 8 bytes of additional space, along
with 2 bytes of relocation data. It also means that extra work needs to
be done at runtime to process these relocations, every time a module is
loaded that incorporates this library.

So fix both issues, by splitting mStatusString into two arrays of char
arrays. The memory footprint decreases from 955 to 843 bytes, and given
that in the latter case, the overhead consists of 278 NUL characters rather
than 390 bytes worth of absolute addresses and relocation records, the size
of a compressed image is reduced even further. For example, when building
ArmVirtQemu.dsc in RELEASE mode for AARCH64 with the GCC5 profile, I get:

  Before

  FV Space Information
  FVMAIN [100%Full] 5329920 total, 5329920 used, 0 free
  FVMAIN_COMPACT [38%Full] 2093056 total, 811840 used, 1281216 free

  After

  FV Space Information
  FVMAIN [100%Full] 5321728 total, 5321728 used, 0 free
  FVMAIN_COMPACT [38%Full] 2093056 total, 809696 used, 1283360 free

So the uncompressed contents of the compressed image are 8 KB smaller,
whereas the resulting flash image (consisting of the compressed image
along with SEC, PEI_CORE and a set of PEIMs that execute in place) is
2 KB smaller.

SafeUint64Mult() looks for 64-bit overflows and performs
several 32-bit multiples with 64-bit results to check for
all possible overflow conditions.  IA32 builds using VS20xx
with optimizations enabled are producing a reference to
the _allmull intrinsic.

The fix is to use MultU64x64() instead of '*' for
these operations.  These are safe because the inputs
are guaranteed to have the upper 32-bits clear, which
means MultU64x64() can never overflow with those inputs.

The current implementation of the FileHandleGetFileName() function
assumes that the Root directory always has the FileName '\0'.
However, the only requirement the UEFI specification defines is that
a prepended '\\' must be supported to access files and folders
relative to the Root directory.
This patch removes this assumption and supports constructing valid
paths for any value of FileName for the Root Directory.

In practice, this fixes compatibility issues with File System drivers
that report '\\' as the FileName of the Root directory, which
currently is both generating an invalid path ("\\\\") and resulting
in an EFI_NOT_FOUND result from the CurrentHandle->Open() call.

variable declarations in nested block scope:

5.4     Code File Structure
5.4.1   Scoping Rules
5.4.1.1 Scope

> Block (local) Scope

>
> Data declarations may follow the opening brace of a compound statement,
> regardless of nesting depth, and before any code generating statements
> have been entered. Other than at the outermost block of a function body,
> this type of declaration is strongly discouraged.

Hoist such variable declarations in Base64Decode() to the outermost
function scope.

Laszlo Ersek 35e242b698 MdePkg/BaseLib: rewrite Base64Decode()
Rewrite Base64Decode() from scratch, due to reasons listed in the second
reference below.

Implement Base64Decode() according to the specification added in the
previous patch. The decoder scans the input buffer once, it has no inner
loop(s), and it spills each output byte as soon as the output byte is
complete.

The intent is to only strengthen the checks (sanity and input) relative to
the previous implementation, hence the MAX_ADDRESS checks are reinstated.

Hao Wu d9f1cac51b MdePkg/BaseLib: Introduce new SpeculationBarrier API
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1417

X86 specific BaseLib API AsmLfence() was introduced to address the Spectre
Variant 1 (CVE-2017-5753) issue. The purpose of this API is to insert
barriers to stop speculative execution. However, the API is highly
architecture (X86) specific, and thus should be avoided using across
generic code.

To address this issue, this patch will add a new BaseLib API called
SpeculationBarrier(). Different architectures will have different
implementations for this API.

For IA32 and x64, the implementation of SpeculationBarrier() will
directly call AsmLfence().

For ARM and AARCH64, this patch will add a temporary empty implementation
as a placeholder. We hope experts in ARM can help to contribute the actual
implementation.

For EBC, similar to the ARM and AARCH64 cases, a temporary empty
implementation is added.

Ard Biesheuvel decaac5d0d MdePkg/BaseMemoryLibOptDxe ARM: add missing function annotations
ARM uses the low order bit of a branch target address to decide in
which execution mode (ARM or Thumb) a function needs to be called.
In order for this to work across object files, ELF function symbols
will have the low bit set if they were emitted in Thumb mode and
cleared otherwise. This annotation is only emitted if the ELF symbols
are annotated as function, since taking the address of some data
symbol (e.g., a literal) should not produce a value with the low bit
set, even if it appears in an object file containing Thumb code.

This means that all functions coded in assembler must have this
function annotation, or they may end up getting called in the
wrong mode, crashing the program.
