how to get the pt trace packet

400 Views

I learned that Intel® Processor Trace (Intel® PT) is supported in Vtune .

Intel PT offers control flow tracing, which includes in data packets timing and program flow information (e.g. branch targets, branch taken/not taken indications) .

How can I get these packets by using this driver? I didn't find these data.

Thanks ahead of time for any help.
