The linux thermal framework doesn't have any support for tracing. This makes it hard to run workloads and observe the thermal behaviour of the system without actively polling files in sysfs or enabling debug builds. This patch set introduces trace events in the framework to allow observing the behaviour of the different components in the framework. The events added trace temperature changes, trip points and cooling device state changes. changes since rfc: * Fixed an issue where incorrect trip point was traced when using fair share * Trace the numeric value of trip_type instead of using __print_symbolic Punit Agrawal (3): thermal: trace: Trace temperature changes thermal: trace: Trace when a cooling device's state is updated thermal: trace: Trace when temperature is above a trip point drivers/thermal/fair_share.c | 12 ++++++ drivers/thermal/step_wise.c | 5 ++- drivers/thermal/thermal_core.c | 7 ++++ include/trace/events/thermal.h | 87 ++++++++++++++++++++++++++++++++++++++++ 4 files changed, 110 insertions(+), 1 deletion(-) create mode 100644 include/trace/events/thermal.h -- 1.7.10.4
