From c5362c0c376486afcf3c91d3c2691d348ac1e2fd Mon Sep 17 00:00:00 2001 From: Maria Dimakopoulou Date: Mon, 17 Nov 2014 20:06:55 +0100 Subject: perf/x86: Add 3 new scheduling callbacks This patch adds 3 new PMU model specific callbacks during the event scheduling done by x86_schedule_events(). ->start_scheduling(): invoked when entering the schedule routine. ->stop_scheduling(): invoked at the end of the schedule routine ->commit_scheduling(): invoked for each committed event To be used optionally by model-specific code.
