How can know the CPU usage for a particular driver?VTUNE will do this, with or without symbols.

Thanks Alberto.
Can TrueTime measure the time spent by drivers that come with OS?

If you have DriverStudio, you can use TrueTime for that. Yet, if you hook every driver in the system your timing’s not going to
be accurate. Alternatively, you can try VTune, which is a sampling tool: your result may not be super accurate, but it’ll give
you some idea.
Hope this helps,
Alberto.

Unless you profile each and every driver on the system , at every particular possible entry point, and then make cumulative
data, this is not possible.

Greeting…
Is there a way to get the CPU usage for a particular driver? I can see the kernel CPU usage in the task manager. But I like to
know what are these kernel time, which driver takes most of the CPU time.
Thanks in advance!
Best Regards,
William
