Definitely, enable_fbc is a win for me and I do manually enable it. But I

This is all on 3.15.4-ARCH-00041-gf4db98240ac2.

Powertop report with FBC: http://pastebin.com/5qfJKpTQ

Seems to have gotten messed up somehow. I can't see the package c-state
info there

Hi Jani,
Is there a way to restore the prior lower power consumption when
idling? As I understand it, FBC should not have a direct effect on
power consumption when idle, only when the FB is actively refreshed.
Is it understood

FBC works best when the screen contents don't change. The more activity
on the screen the less effective FBC becomes. 4W sounds way too much for
FBC however. 0.4W is closer to what one might expect from FBC

Could the FBC commit somehow also disable RC6, or similar?
I just tried these kernel arguments with no significant effect on
power consumption (i.e. still around 11W in idle, instead of under
7W):

Any significant changes in package C state as reported in powertop?

Hi Jani,
Is there a way to restore the prior lower power consumption when
idling? As I understand it, FBC should not have a direct effect on
power consumption when idle, only when the FB is actively refreshed.
Is it understood why no FBC would have such a dramatic impact (+4W) on
a system sitting
