perf report: Add --percent-type option Set annotation percent type from following choices: global-period, local-period, global-hits, local-hits With following report option setup the percent type will be passed to annotation browser: $ perf report --percent-type period-local The local/global keywords set if the percentage is computed in the scope of the function (local) or the whole data (global). The period/hits keywords set the base the percentage is computed on - the samples period or the number of samples (hits).
