Currently the command line option settings beats the per event period settings: With no global settings, we get per-event configuration: $ perf record -e 'cpu/instructions,period=20000/' sleep 1 $ perf evlist -v ... { sample_period, sample_freq }: 20000 ... With 'c' option period setup, we get 'c' option value: $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1 $ perf evlist -v ... { sample_period, sample_freq }: 1000 ... This patch makes the per-event settings overload the global 'c' option setup: $ perf record -e 'cpu/instructions,period=20000/' -c 1000 sleep 1 $ perf evlist -v ... { sample_period, sample_freq }: 20000 ... I think the making the per-event settings to overload any other config makes more sense than current state. However it breaks the current 'period' term handling, which might cause some noise.. so let's see ;-). Also fixing parse event tests with the new behaviour.
