RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3937 Memory usage may exceed the amount accepted at the begining (SEC), TDVF needs to accept memory dynamically when OUT_OF_RESOURCE occurs. Another usage is in SetOrClearSharedBit. If a memory region is changed from shared to private, it must be accepted again. EdkiiMemoryAcceptProtocol is defined in MdePkg and is implementated / installed in TdxDxe for Intel TDX memory acceptance.
