PCM is similar and is userspace. However on OSX, you need a driver and then various other hoops must be jumped in order to enable it. On Linux, I think it just runs out of the box. But in any case, PCM itself is userspace.

- gens 10y agoThere 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.
