^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 68) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 69) Performance counters for Linux are a new kernel-based subsystem
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 70) that provide a framework for all things performance analysis. It
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 71) covers hardware level (CPU/PMU, Performance Monitoring Unit) features
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 72) and software features (software counters, tracepoints) as well.
