Topic: sightglass performance counters reading zero

I have a weird case when running sightglass (on Ubuntu 22.04, x86-64) measuring with performance counters. They all read zero!
The test in counters.rs in the recorder crate, works perfectly fine and reads sensible values, but when I run any benchmark with sightglass-cli, the reading of counter values return zeros. No reset of the counters take place between the start and the end measurements.

Any pointers on how to debug?

It turns out removing --pin leads to some meaningful results.
