Hi,
I have started to use the new cpuidle tracepoint and created a plugin
for pytimechart.
I'm not sure if it's the right way to add this cpuidle trace format
update but it's the less intrusive one.
I also have a plugin for new cpu_hotplug trace points but i'm waiting
for trace approval before sending it
