This article would have been easier to follow with some detail as to what information these facilities extract from the hardware. Something more detailed than "support for low-level optimization of critical code."
I get particularly lost trying to understand counters overflowing and reading batches of something, which is given as a feature of the Gleixner/Molnar scheme.
