Oleg Ilyasov 1a440d9638 Retrieve the USB class specific data from the configuration descriptor
If USB device reports class specific descriptors, it is currently the job of
device driver to parse the configuration to find the class specific data.
The new library functions parse the configuration descriptor and return class
specific interface and class specific endpoint descriptors.
Also, these new functions allow to retrieve the data from non-default alternate
settings without performing a switch to this setting. Switching to the
alternate setting currently implies the execution of UsbSetInterface function
that performs USB control trnasfer.
In some cases this switch is not desirable so the new functions
UsbGetInterfaceDescriptorSetting and UsbGetEndpointDescriptorSetting come
in handy.

Mike Beaton ae83c6b7fd MdePkg: Fix null macros for XCODE5 and CLANG
When building OvmfPkg in RELEASE mode in the XCODE5 toolchain, the
ASSERT_EFI_ERROR change prevents this error:

.../MdePkg/Library/UefiMemoryAllocationLib/MemoryAllocationLib.c:141:15:
error: variable 'Status' set but not used [-Werror,-Wunused-but-set-variable]
  EFI_STATUS  Status;
              ^

which is currently stopping the build.

When building in RELEASE mode in the CLANGPDB toolchain,the DEBUG macro
change prevents this error:

.../edk2/OvmfPkg/VirtioSerialDxe/VirtioSerial.c:28:22: error:
variable &apos;EventNames&apos; is not needed and will not be
emitted [-Werror,-Wunneeded-internal-declaration]
STATIC CONST CHAR8  *EventNames[] = {
                     ^

which is currently stopping the build.

CLANGDWARF produces the same error as CLANGPDB above, if
-Wno-unneeded-internal-declaration is removed from its build flags.
With the null DEBUG macro change, this warning suppression
can be removed from CLANGDWARF, which is considered a benefit
as it has the potential to catch real coding errors. This is
done in a subsequent commit.

This commit has the desirable side effect that we no longer require
(and cannot use) explicit `#ifndef MDEPKG_NDEBUG` around items only
used in DEBUG macros. This requires the ArmPkg change made here to
be in the same commit as the MdePkg changes.

Note: In common with existing macros in EDK II, including the pre-existing
and unchanged DEBUG/NOOPT versions of the macros which are modified here,
we use the standard approach of adding `do { ... } while (FALSE)` wrapping
to ensure that the macros behave correctly with surrounding code
(e.g. require a following ';' and do not combine in unexpected ways with
nearby conditionals).

Oliver Smith-Denny d99045f392 MdePkg: DebugLib: Check Signature in CR in Release Builds
The CR macro is used to access an enclosing structure from a
pointer within the structure. In DEBUG builds (i.e. when
MDEPKG_NDEBUG is not set and debug asserts are enabled), this
macro does signature validation checking to ensure that the
structure that has been found is the correct structure, based
on a signature passed in by the caller.

However, if MDEPKG_NDEBUG is set or debug asserts are disabled,
no signature validation is performed, meaning that CR may return
an invalid structure that the caller believes is valid and has had
signature validation on, causing undefined behavior (memory
corruption). We should where at all possible have defined behavior,
particularly in RELEASE builds, which are what typical platforms
will ship to consumers.

This patch updates CR to do the signature validation in all scenarios
to provide defined behavior from the macro. In the event of a
signature failure, CR will either 1) assert if !MDEPKG_NDEBUG and
debug asserts are enabled (existing behavior) or 2) return NULL to
indicate to the caller that signature validation failed.

There exist consumers today who already, erroneously, rely on this
behavior.

Another macro, BASE_CR, exists for callers who do not wish to perform
signature validation. Any code that wishes to avoid the signature
validation should move to this macro.

FdtNumRsv and FdtGetMemRsv were added for the benefit of UefiPayloadPkg,

Mike Beaton 0aa93aecb7 MdePkg: Fix DEBUG_CODE and PERF_CODE macros for XCODE5
Without these changes, we get the error:

  error: variable '__DebugCodeLocal' set but not used

from the DebugLib.h DEBUG_CODE_BEGIN()/END() macros on XCODE5.

Similarly, in NOOPT builds only, we get:

  error: variable '__PerformanceCodeLocal' set but not used

from the PerformanceLib.h PERF_CODE_BEGIN()/END() macros on XCODE5.

It is important to note that the previous code involving a local
variable was intended to ensure correct behaviour of ; following
the macros, in particular that ; should be required:
 - https://github.com/tianocore/edk2/pull/6226#issuecomment-2364087866
 - https://github.com/tianocore/edk2/pull/6226#issuecomment-2364619759
This converted version repeats the
standard do { ... } while (FALSE) idiom (which is already used in
the END macro) to achieve the same affect.

The modified versions work on all toolchains.

Taylor Beebe ac43bbacde MdePkg: Create Stack Check Null Libs
Add Null libs for Stack Check and Stack Check Failure Hook Lib that
allow a platform to opt out of stack checks and the stack check failure
hook lib.

StackCheckLib allows implementation (or in this case null implementation)
of stack checks on binaries. There is a Host Application specific version
of this null lib because MSVC host applications must not be linked against
our lib (so the file here is a no-op but that doesn't cause the build
system to fail the build for not building a file for MSVC) as it links
against the MSVC C runtime lib that provides the stack cookie definitions.
GCC host applications do not link against such a C runtime lib and must
be linked against our version.

StackCheckFailureHookLib lets a platform do custom functionality when a
stack check failure occurs (such as log it to a platform defined
mechanism). The null lib simply returns.

Tom Lendacky c0bf953fe8 MdePkg/BaseLib: Add a new VMGEXIT instruction invocation for SVSM
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654

The SVSM specification relies on a specific register calling convention to
hold the parameters that are associated with the SVSM request. The SVSM is
invoked by requesting the hypervisor to run the VMPL0 VMSA of the guest
using the GHCB MSR Protocol or a GHCB NAE event.

Create a new version of the VMGEXIT instruction that will adhere to this
calling convention and load the SVSM function arguments into the proper
register before invoking the VMGEXIT instruction. On return, perform the
atomic exchange on the SVSM call pending value as specified in the SVSM
specification.

platform. This register can be used to set the timer interrupt directly in
S-mode instead of going via SBI call. Add a function to update this
register.

Dhaval 26727c2ae2 MdePkg: Implement RISC-V Cache Management Operations
Implement Cache Management Operations (CMO) defined by
RISC-V spec https://github.com/riscv/riscv-CMOs.

Notes:
1. CMO only supports block based Operations. Meaning cache
   flush/invd/clean Operations are not available for the entire
   range. In that case we fallback on fence.i instructions.
2. Operations are implemented using Opcodes to make them compiler
   independent. binutils 2.39+ compilers support CMO instructions.

Test:
1. Ensured correct instructions are refelecting in asm
2. Qemu implements basic support for CMO operations in that it allwos
   instructions without exceptions. Verified it works properly in
   that sense.
3. SG2042Pkg implements CMO-like instructions. It was verified that
   CpuFlushCpuDataCache works fine. This more of less
   confirms that framework is alright.
4. TODO: Once Silicon is available with exact instructions, we will
   further verify this.

Dhaval 30faafd024 MdePkg: Rename Cache Management Function To Clarify Fence Based Op
There are different ways to manage cache on RISC-V Processors.
One way is to use fence instruction. Another way is to use CPU
specific cache management operation instructions ratified as
per RISC-V ISA specifications to be introduced in future
patches. Current method is fence instruction based, rename the
function accordingly to add that clarity.

instead of instance source file. This helps with further restructuring

Pedro Falcato e2d4f75913 MdePkg/BaseLib: Fix CRC16-ANSI calculation
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4609

The current CalculateCrc16Ansi implementation does the following:
1) Invert the passed checksum
2) Calculate the new checksum by going through data and using the
   lookup table
3) Invert it back again

This emulated my design for CalculateCrc32c, where 0 is
passed as the initial checksum, and it inverts in the end.
However, CRC16 does not invert the checksum on input and output.
So this is incorrect.

Fix the problem by not inverting input checksums nor output checksums.
Callers should now pass CRC16ANSI_INIT as the initial value instead of
"0". This is a breaking change.

This problem was found out-of-list when older ext4 filesystems
(that use crc16 checksums) failed to mount with "corruption".
