The DXE Core is one of those modules that call ProcessLibraryConstructorList() manually. Before DxeMain() [MdeModulePkg/Core/Dxe/DxeMain/DxeMain.c] calls ProcessLibraryConstructorList(), and through it, our PlatformDebugLibIoPortConstructor() function, DxeMain() invokes the DEBUG() macro multiple times. That macro lands in our PlatformDebugLibIoPortFound() function -- which currently relies on the "mDebugIoPortFound" global variable that has (not yet) been set by the constructor. As a result, early debug messages from the DXE Core are lost. Move the device detection into PlatformDebugLibIoPortFound(), also caching the fact (not just the result) of the device detection. (We could introduce a separate DebugLib instance just for the DXE Core, but the above approach works for all modules that currently consume the PlatformDebugLibIoPort instance (which means "everything but SEC").) This restores messages such as: > CoreInitializeMemoryServices: > BaseAddress - 0x7AF21000 Length - 0x3CDE000 MinimalMemorySizeNeeded - 0x10F4000 Keep the empty constructor function -- OVMF's DebugLib instances have always had constructors; we had better not upset constructor dependency ordering by making our instance(s) constructor-less.
