Rafael,
The DebugAgentLib is designed to hook into various fundamental chunks of the
system. It is not designed to hook into your application.
So for example the DXE Core consumes the DebugAgentLib, and the default link is
to point it to a NULL version. If you point the DXE Core at the
DxeDebugAgentLib.inf instance of the DebugAgentLIb then you should get source
level debugging in EFI. Note you also have to make sure any libraries the
DxeDebugAgentLib.inf require also point the the correct ones.
