Perf record will collect required retire_latency values in parallel while perf stat is collecting counting va= lues. At the point of time that perf stat stops counting, evsel would stop perf r= ecord by sending sigterm signal to perf record process. Sampled data will be proc= ess to get retire latency value. Another thread is required to synchronize betw= een perf stat and perf record when we pass data through pipe. Retire_latency evsel is not opened for perf stat so that there is no counter wasted on it. This commit includes code suggested by Namhyung to adjust rea= ding size for groups that include retire_latency evsels.

charset="utf-8" From: Weilin Wang In current :R parsing implementation, the parser would recognize events with retire_latency modifier and insert them into the evlist like a normal event. Ideally, we need to avoid counting these events. In this commit, at the time when a retire_latency evsel is read, set the re= tire latency value processed from the sampled data to count value. This sampled retire latency value will be used for metric calculation and final event co= unt print out. No special metric calculation and event print out code required = for retire_latency events.
