From 06cc1a470ab237b991901729b125404c164f3660 Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Thu, 18 Jan 2018 13:26:29 -0800 Subject: perf hists browser: Add parameter to disable lost event warning For overwrite mode, the ringbuffer will be paused. The event lost is expected. It needs a way to notify the browser not print the warning. It will be used later for perf top to disable lost event warning in overwrite mode. There is no behavior change for now.
