Current memory profile feature: 1. Shows which line of code calls gBS->AllocateXXX(). But most entries are from MemoryAllocationLib. 2. Records at the start. 3. Records all modules. Enhanced memory profile feature: 1. User can know which line of code calls AllocateXXX() API instead of gBS->Allocate(). 2. User can know which line of code calls a specific API that will call AllocateXXX(). 3. User can know total memory allocated by a specific line of code. 4. User can configure to record single module. 5. User can configure when to enable recording. 6. User can know RVA<->Symbol (Function, Source, Line). For the enhanced memory profile feature, 1. Extend MEMORY_PROFILE_DRIVER_INFO to include PdbString. 2. Extend MEMORY_PROFILE_ALLOC_INFO to include ActionString. 3. Extend MEMORY_PROFILE_ACTION to indicate action in memory allocation lib and user defined action. 4. Extend memory profile protocol to include GetRecordingState/ SetRecordingState/Record. 5. Define SMM memory profile protocol. 6. Extend PcdMemoryProfilePropertyMask to support disable recording at the start. 7. Introduce new PCD PcdMemoryProfileDriverPath to control which drivers need memory profile data.
