PM / QoS: Add dev_pm_qos_request tracepoints

2013-06-24T11:09:03Z

Adds tracepoints to dev_pm_qos_add_request, dev_pm_qos_update_request, and dev_pm_qos_remove_request. It's useful for checking device name, dev_pm_qos_request_type, and value. Signed-off-by: Sahara Signed-off-by: Rafael J. Wysocki

PM / QoS: Add pm_qos_request tracepoints

2013-06-24T11:09:03Z

Adds tracepoints to pm_qos_add_request, pm_qos_update_request, pm_qos_remove_request, and pm_qos_update_request_timeout. It's useful for checking pm_qos_class, value, and timeout_us. Signed-off-by: Sahara Signed-off-by: Rafael J. Wysocki

PM / QoS: Add pm_qos_update_target/flags tracepoints

2013-06-24T11:09:03Z

This patch adds tracepoints to pm_qos_update_target and pm_qos_update_flags. It's useful for checking pm qos action, previous value and current value. Signed-off-by: Sahara Signed-off-by: Rafael J. Wysocki

PM / tracing: remove deprecated power trace API

2013-01-25T23:39:12Z

The text in Documentation said it would be removed in 2.6.41; the text in the Kconfig said removal in the 3.1 release. Either way you look at it, we are well past both, so push it off a cliff. Note that the POWER_CSTATE and the POWER_PSTATE are part of the legacy tracing API. Remove all tracepoints which use these flags. As can be seen from context, most already have a trace entry via trace_cpu_idle anyways. Also, the cpufreq/cpufreq.c PSTATE one is actually unpaired, as compared to the CSTATE ones which all have a clear start/stop. As part of this, the trace_power_frequency also becomes orphaned, so it too is deleted. Signed-off-by: Paul Gortmaker Acked-by: Steven Rostedt Signed-off-by: Rafael J. Wysocki

PM / Sleep: Add wakeup_source_activate and wakeup_source_deactivate tracepoints

2012-05-01T19:25:25Z

Add tracepoints to wakeup_source_activate and wakeup_source_deactivate. Useful for checking that specific wakeup sources overlap as expected. Signed-off-by: Arve Hjønnevåg Acked-by: Greg Kroah-Hartman Signed-off-by: Rafael J. Wysocki

x86/tracing: Denote the power and cpuidle tracepoints as _rcuidle()

2012-02-13T14:14:43Z

The power and cpuidle tracepoints are called within a rcu_idle_exit() section, and must be denoted with the _rcuidle() version of the tracepoint. Acked-by: Paul E. McKenney Reviewed-by: Josh Triplett Signed-off-by: Steven Rostedt

perf: Clean up power events by introducing new, more generic ones

2011-01-04T07:16:54Z

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.
