You may try report the FVMAIN_COMPACT with the way like below. Then PeiCore's
FvInfo notification will decompress the FVMAIN_COMPACT and build FV HOB for
decompressed FVMAIN for DXE phase. FvInfo is the standard way, FvHob is produce
for DXE phase. PeiCore only processes FvHob when
PcdFrameworkCompatibilitySupport = TRUE.
//
// Let PEI know about the DXE FV so it can find the DXE Core
//
PeiServicesInstallFvInfoPpi (
NULL,
(VOID *)(UINTN) PcdGet32 (PcdOvmfDxeMemFvBase),
PcdGet32 (PcdOvmfDxeMemFvSize),
NULL,
NULL
);

Sorry, adding fine-grained debug messages (or source level debugging, as you
say) is my only thought at this point.
