Hello,
is it posible to get information on kernel control paths that are executed in the context of some process. On interrupts?

Dear eli,

Thanks for the great question.

VTune DEV tells me this functionality does not yet exist with our current product: in a way, it sounds like you want callgraph for kernel processes, yes?

Currently, the call graph software works only on user-level processes; but I've forwarded your idea on.

Please let me know if this makes sense to you, or if I've misunderstood the question.

cheers

Please forward another request for similar kind of functionality: call-graph profiling for kernel and kernel loadable modules code.

In the meanwhile - is it currently possible to use the VTune API (from kernel code) in order to achieve these goals?

Thanks,

Giora

Hi Jeff,
you correctly understood what I meant. I want to trace my code from the time it while it's executed in the kernel as well as in user space.
thanks
