Powertop Support via timer_stats (patch included)
I noticed that the freetz kernel (2.6.19) in my case (7570) doesn't support timer_stats. But it's really easy to add. The patch applies almost entirely without issues. The patch can be found here. http://lkml.org/lkml/2006/10/4/265
I've applied with "fuzz factor" of 300 lines (patch -F 300). Then only the Makefile needs to be modified: source/kernel/ref-ur8-16mb-7270_04.86/linux/kernel/time/Makefile add timer_stats.o at the end of the line.
I couldn't try it out yet, as current SVN freetz on longer supports images < 8 MB and I have a split mtd1.
Could someone try this out and apply this to the sources? Thanks!
