I tried to run powerTop to monitor power consumption on an omap4 board
(pandaboard) and actually it's running on. However, I couldn't get C-states
that I expected. Due to the omap4 characteristics, it's supposed to have C0
to C6 states but my powerTop has only C1 to C3.
Based on this manual (
additional patch would be required to update c-states for omap architecture
but I couldn't find the files (powertop.c, powertop.h display.c) as
described in this manual.
Does anybody run powerTop on omap4 (or pandaboard) environment? Could you
share how did you set up powerTop on omap4 architecture?
