I am trying to test TDX functionality with config A patches (Wave1 + Wave2.v4) and with the above function passing the memory attributes of the resources in TD HOB list (Originally populated by VMM) as is to DXE phase,
Function CoreInitializeMemoryServices (from ./MdeModulePkg/Core/Dxe/Gcd/Gcd.c) is not able to find any resources with TESTED_MEMORY_ATTRIBUTES set.

For config A, Is there an expectation from VMM to set TESTED_MEMORY_ATTRIBUTES for each System Memory resource passed via TD HOB list or should this function
be appending TESTED_MEMORY_ATTRIBUTES to existing resource attributes?

Regards,
Vishal
