       The  tool  gathers  data  using  perf performance counters (PMU) exposed by i915 and other

       -o <filepath|->

LIMITATIONS

       • Not all metrics are supported on all platforms. Where a metric is unsupported it's value
         will be replaced by a dashed line.

       • Non-root access to perf counters is controlled by the perf_event_paranoid sysctl.
