REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4568

The function InstallCloudHvTablesTdx had an Assert when "DsdtTable ==
NULL", but this comes into play only in DEBUG mode. In Release mode ,
there is no handling if the pointer is NULL. To avoid the possible null
pointer dereference, it is better to handle it when the pointer is null.

In addition, the status of "AcpiProtocol->InstallAcpiTable" is overwritten
before it can be used in the function, it is better to check it before
overwriting.

Rebecca Cran 8ba392687b OvmfPkg: Update code to be more C11 compliant by using __func__
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.

Since it's more standard, replace __FUNCTION__ with __func__ throughout
OvmfPkg.

Min M Xu 7cd55f3009 OvmfPkg/AcpiPlatformDxe: Return error if installing NotifyProtocol failed
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4237

Installation of gQemuAcpiTableNotifyProtocol may fail. The error code
should be returned so that the caller can handle it.

Min M Xu f81273f7fb OvmfPkg/AcpiPlatformDxe: Use local variable in CloudHvAcpi.c
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4237

The handle of mChAcpiHandle is not needed for anything, beyond the
scope of the InstallCloudHvTablesTdx (). A local variable (ChAcpiHandle)
suffices for storing the handle.

Min M Xu 43b3ca6b7f OvmfPkg/AcpiPlatformDxe: Remove QEMU_ACPI_TABLE_NOTIFY_PROTOCOL
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4237

The QEMU_ACPI_TABLE_NOTIFY_PROTOCOL structure is superfluous because NULL
protocol interfaces have been used in edk2 repeatedly. A protocol instance
can exist in the protocol database with a NULL associated interface.
Therefore the QEMU_ACPI_TABLE_NOTIFY_PROTOCOL type, the
"QemuAcpiTableNotify.h" header, and the "mAcpiNotifyProtocol" global
variable can be removed.

Sebastien Boeuf e254c71e9e OvmfPkg/AcpiPlatformDxe: Differentiate TDX case for Cloud Hypervisor
Rely on CcProbe() to identify when running on TDX so that ACPI tables
can be retrieved differently for Cloud Hypervisor. Instead of relying on
the PVH structure to find the RSDP pointer, the tables are individually
passed through the HOB.
