[PATCH 10/25] perf intel-pt: Ensure IP is zero when state is INTEL_PT_STATE_NO_IP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

A value of zero is used to indicate that there is no IP. Ensure the
value is zero when the state is INTEL_PT_STATE_NO_IP.
