The previous ones were [1], [2], [3], [4]. This one addresses review comments in patches 1/7 and 2/7, the tooling patches are intact, but I'm including them anyway. The PEBS feature: output to Intel PT stream instead of the DS area. It's theoretically useful in virtualized environments, where DS area can't be used. It's also good for those who are interested in instruction trace for context of the PEBS events. As PEBS goes, it can provide LBR context with all the branch-related information that PT doesn't provide at the moment. PEBS records are packetized in the PT stream, so instead of extracting them in the PMI, we leave it to the perf tool, because real time PT decoding is not practical.
