+PARAMETERIZED EVENTS
+--------------------
+
+Some pmu events listed by 'perf-list' will be displayed with '?' in them. For
+example:
+
+  hv_gpci/dtbp_ptitc,phys_processor_idx=?/
+
+This means that when provided as an event, a value for phys_processor_idx must
+also be supplied. For example:
+
+  perf stat -e 'hv_gpci/dtbp_ptitc,phys_processor_idx=0x2/' ...
