So it turns out that there is no direct way to enable CONFIG_TRACING. If
you have perf enabled then powertop won't spit out the diagnostic message
telling you to enable both perf and trace. After an hour of rooting
through Kconfig files, I finally figured out the quickest way to enable
TRACING was in the Kernel hacking menu ; Tracers (CONFIG_FTRACE) ; Kernel
Function Tracer (CONFIG_FUNCTION_TRACER), which selects GENERIC_TRACER
which in turn selects CONFIG_TRACING.
Did I miss something obvious in the docs?

Yeah it seems you have to enable CONFIG_FTRACE.
So maybe powertop should suggest this one in the first place?

@Edwin and Brad: Thanks for finding this out - I'll send a patch that spits
out the message if access to /sys/kernel/debug/tracing/events fails.

Now I've attached my powertop.html file so you can see what I'm on about.

The old powertop used to identify wakeups to processes. Mine just gives me loads of timers with no 
process data attached. Is there some other config entry I was supposed to enable for it to output 
meaningful data?

Just in case it's important, I'm using a 32bit userspace on a 64bit kernel.

Regards,
Brad
