There are generic tools for these stuff on linux like perf, powertop, slabtop, lm-sensors, and probably more that idk about. This PCM looks like it provides information that the tools above can't, like pcm and memory bandwidths (unless i misunderstood what it does). Sucks that it's intel only, i'd like to watch memory bandwidth usage on my amd. Unrelated: this reminds me of mcelog, that collects hardware errors.
