If I have an application that dlopen()s a DSO, is there any way to make VTune instrument that DSO and profile it?
It does not matter how you use you DSO: either implicit loading: -lYourDSO (in the linker command line) or explicit one: dlopen.In both cases VTune analyzer for Linux analyze your DSO according to a possible instrumentation level.The command bellow configures and runs an activity for the application myapp located in the directory mydir. All the DSOs this application uses will be analyzed according to the debug information level they have.
>vtl activity -c callgraph -app /mydir/myapp -moi /mydir/myapp run
Please feel free to ask if you have any further questions.
