Hi Srinivas,

As discussed, I have a couple of powertop questions, thanks for passing
them on.
I did try the mailing list:
Date: Fri, 2 Aug 2013 10:27:38 -0700
From: Marc MERLIN <marc_powertop(a)merlins.org>
To: powertop(a)ml01.01.org

but I never heard anything back. Is the list mostly dead, or is there
another list?

So, I got powertop 2.4 from
https://01.org/powertop/downloads/2013/powertop-v2.4

Like I showed you on my laptop, when I go left and right with my arrows,
I'm on the Overview screen, and I can't move to Idle stats or Freq stats
like I could in older powertops:

----------------------------------------------------------------------------

----------------------------------------------------------------------------

Separately, it reports this:
   1.25 W    100.0%    Device   USB device: Integrated Camera (Chicony Electronics Co., Ltd.)

It's on a thinkpad T530. I haven't found a way to stop that.
I've unloaded the uvcvideo driver, but generally haven't found
anything else I can do.

If you have any ideas, it would be greatly appreciated.

Thanks,
Marc

in order to move between tabs use TAB button.

That works indeed, I didn't realize it changed.

I think Chris had to do that since he implemented scrollable ncurses
windows, and you need up/down/left/right to move the viewport around.
It's been a while that this code was in and the announcement went
out... sadly it's hard to get distros to pick up details like that.

PowerTOP UI navigation enhancement(v3).

    "Arrow Keys" now scroll the tab windows
    "Page up/down" scroll tab windows up and down
    "TAB" cycles the next window tab
    "SHIFT+TAB" cycles the previous window tab
    "ENTER" toggles tunables
    "SPACE BAR" toggles tunables
    "r KEY" refresh results and resets view of tab window.
---

it was in 2.2 release. I think the problem is that there was no
2.2 release annoucement and that change went unmentioned, so one
year later we still sometimes see such questions.

No worries at all, it happens :)

By the way, my more nagging question was, how can I stop the built in camera
in my T530 from taking so much power? (I'm sure the number is wrong, but still)

The battery reports a discharge rate of 18.4 W
The estimated remaining time is 4 hours, 18 minutes

Summary: 657.6 wakeups/second,  28.4 GPU ops/seconds, 0.0 VFS ops/sec and 9.3% CPU use

Power est.  Usage       Events/s   Category       Description
  12.2 W    100.0%                 Device         USB device: Integrated Camera (Chicony Electronics Co., Ltd.)
  997 mW     60.0%                 Device         Display backlight
 76.1 mW     34.9 µs/s      34.8   Process        [rcu_preempt]
 23.1 mW      1.5 ms/s      16.5   Process        xfce4-terminal -T window11 --role=window11
 9.20 mW     59.0 ms/s     347.4   Process        /usr/bin/enlightenment

Note that tunables says:
   Good          Autosuspend for USB device Integrated Camera [Chicony Electronics Co., Ltd.]

Kernel 3.10.6.

Any ideas?

Thanks,
Marc

Yes it's been that way for a while now.

How about unloading/blacklisting its driver?

That didn't help. 

It might work if I blacklist the driver and never use it after boot, but
that's not super compatible with google talk/hangouts.

That said, if I can't get the driver/device to behave, I might do that.
