Yaoping. Thanks for the solution.
I also have another small question -
As stated in the Intel manuals,
The Pentium 4 and Intel Xeon processors performance
monitoring facilities support the three usage models -
1: "Event Couting",
2: "Non-precise event-based sampling",
3: "Precise event-based sampling (PEBS)"
I Would like to know if the Uop-tagging mechanism for
"At-retirement events" (front-end tagging, execution
tagging and replay tagging) exists only for the latter
2 usage models ? Does it exist for the "Event
Counting" Usage model ?
