Subject: [PATCH v5 16/16] perf record: Retirement latency cleanup in evsel__config
Date: Mon, 14 Apr 2025 10:41:34 -0700 [thread overview]
Message-ID: <20250414174134.3095492-17-irogers@google.com> (raw)
In-Reply-To: <20250414174134.3095492-1-irogers@google.com>
Perf record will fail with retirement latency events as the open
doesn't do a perf_event_open system call. Use evsel__config to set up
such events for recording by removing the flag and enabling sample
weights - the sample weights containing the retirement latency.
