rdpmc library

rdpmc library

i'm trying to count the number of instructions retired between two points in a windows7 device driver.

is there sample code or a library function to achieve this, or do i have to __asm rdpmc ?

You could insert VTune API calls to turn on and off counting at the points of interest.

However, be reminded that the VTune analyzer does statistical profiling and will not give you an EXACT count of instructions retired between two points.
