I am a little confused because I do not get this level of PMU access on AWS instances short of "metal". Usually if I want to analyze some performance problem I need to move the workload to "metal" instance types and usually the c6i.metal, since the Ice Lake PMU is so much more capable.

If I try to count machine clears on a non-metal instance perf tells me the event doesn't exist, and if I give it the raw event encoding it runs but says the event isn't supported.
