Various authors, David Sharp isn't currently at Google. v3. moved a loop into a helper following Adrian Hunter's suggestion. v2. corrects the commit message following Athira Rajeev's suggestion. David Sharp (1): perf record: Set PERF_RECORD_PERIOD if attr->freq is set. Ian Rogers (2): perf record: Don't clear event's period if set by a term perf test: Leader sampling shouldn't clear sample period Stephane Eranian (1): perf record: Prevent override of attr->sample_period for libpfm4 events tools/perf/tests/attr/README | 1 + tools/perf/tests/attr/test-record-group2 | 29 ++++++++++++++++++++ tools/perf/util/evsel.c | 10 ++++--- tools/perf/util/record.c | 34 ++++++++++++++++++------ 4 files changed, 63 insertions(+), 11 deletions(-) create mode 100644 tools/perf/tests/attr/test-record-group2 -- 2.28.0.618.gf4bc123cb7-goog
