Subject: [PATCH 1/2] perf top: update event name when falling back to cpu-clock
perf-top falls back to cpu-clock if the H/W cycles event is not
supported, but the event name is not updated leading to a
misleading header:
PerfTop: 8 irqs/sec kernel:75.0% exact: 0.0% [1000Hz cycles], ...
Update the event name when the event type is changed so that the
header displays correctly:
PerfTop: 794 irqs/sec kernel:100.0% exact: 0.0% [1000Hz cpu-clock], ...
