The PowerTop prototype is getting to be in pretty good shape. It's
tracking wake-ups from all the relevant events:
- timeouts / callouts
- cyclic firings (including clock)
- Interrupts
...and seems to be doing a reasonable job tracking the CPU time spent
running at various frequencies, as well as time spent in the c-states we
currently support.
I've posted a webrev of the changes in the powertop repository vs.
snv_75, which is available at:
http://cr.opensolaris.org/~esaxe/powertop/
..and also from the PowerTop project page. There's still some bugs
(things not adding up to 100%, etc)...and I need to pursue getting the
power related DTrace probes back into onnv so that the tool can be
otherwise self contained.
Thanks,
