Hello,
Is it possible to use call graph to profile an application written as a collection of kernel level drivers?
According to the documentation, Vtune call graph profiler can only instrument Ring 3 modules and not Ring 0 modules. Is this statement true even if symbol and base relocation information is available?
Many thanks,

VTune Analyzer only instruments and collects data about Ring 3 applications. However, with sampling, Ring 0 code can be analyzed as well (but not for Call Graph). Also, Pause/Resume APIs are appropriate in Ring 3 code only.
Sorry.
