From 25e41933b58777f2d020c3b0186b430ea004ec28 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Mon, 3 Jan 2011 17:50:44 +0100 Subject: perf: Clean up power events by introducing new, more generic ones Add these new power trace events: power:cpu_idle power:cpu_frequency power:machine_suspend The old C-state/idle accounting events: power:power_start power:power_end Have now a replacement (but we are still keeping the old tracepoints for compatibility): power:cpu_idle and power:power_frequency is replaced with: power:cpu_frequency power:machine_suspend is newly introduced. Jean Pihet has a patch integrated into the generic layer (kernel/power/suspend.c) which will make use of it. the type= field got removed from both, it was never used and the type is differed by the event type itself. perf timechart userspace tool gets adjusted in a separate patch.
