2014-11-17load_and_build_cstate_info: Plug a memory leak in error pathTuukka Tikkanen
This patch plugs a leak that occurs when cstate data is not what we expect. Signed-off-by: Tuukka Tikkanen <tuukka.tikkanen@linaro.org>
2014-11-14idlestat: Add code to store and load c-state infoKoan-Sin Tan
Add output_cstate_info() to store c-state information into idlestat trace file. Add load_and_build_cstate_info() to read/import trace with c-state information. For idlestat log, c-state information are stored after topology information. For ftrace and 'trace-cmd report' formats, since there is no topology and c-state information stored, read them from sysfs on the current running machine for now (which means you still have to process them on the same machine).

2014-10-30Energy_model: Do not fail when no energy model is usedTuukka Tikkanen
Previous patchset unconditionally tries to load energy model, even if the energy model file is not specified (i.e. energy model processing is not desired). This patch modifies the code to skip parsing energy model in case it is not specified. The call to parsing energy model is moved from getoptions() to main().

2014-10-24idlestat: port Patrick's energy model improvementsLarry Bassel
This is a port of Patrick Bellasi's energy model improvements to the current idlestat tip. These are taken from his idlestat tree which is located at git@github.com:scheduler-tools/idlestat.git The commits used are listed below. They were squashed, ported and some cleanup was performed. Some very TC2-specific code (hwmon) was removed -- it may be possible in the future to generalize this to make it useful to all platforms. commit 08b13eecbc1bf9d8514d92bded54f3e9407b39b2 Author: Patrick Bellasi <patrick.bellasi@arm.com> Date: Fri Jul 25 14:16:34 2014 +0100 energy_model: fix scaling of wakeup energy components This should fix the scaling of wakeup energy components to match the energy model parameters. Basically, since the scheduler model is normalized to a wake-up rate of 1000 wake-ups per second, the correct conversion is: idlestate_wakeup_energy = sched_wakeup_energy * 47742 / (1000 * 1024) Where: - 47742: Removes wake-up tracking pre-scaling - 1024: Removes << 10 - 1000: Single wake-up instead of 1000/s Signed-off-by: Patrick Bellasi <patrick.bellasi@arm.com> commit ff949c959ff3cee3df371451b686a11ebafcfe4e Author: Patrick Bellasi <patrick.bellasi@arm.com> Date: Thu Jul 24 14:26:06 2014 +0100 energy_model: report per-cluster power breakdown At the end of an experiment, dump energy estimation per each cluster as well as the overall energy.

And example of the the newer format is: <idle>-0 [002] .N.. 1420.031852: cpu_idle: state=4294967295 cpu_id=2 where as the older format is: <idle>-0 [000] 91.365043: cpu_idle: state=1 cpu_id=0 The modified TRACE_FORMAT will handle both inputs by consuming characters upto the floating point time field.
