Strange Behavior - PowerTOP 2.0 Seg Fault
by cshanahan＠comcast.net
Hello,
I was reading PowerTOP documentation and was curious whether it could help me better manage power on my HP EliteBook 6930p laptop. I am running PowerTOP v.2.0 on openSUSE 12.2 64-bit. After looking at some of my options from the Overview and Stats tabs, I elected to run 'powertop --calibrate' as the docs suggest. PowerTOP did not complete the calibration process; it exited with a seg fault. Now the hardware button for WiFi (small button along the top of the laptop near the screen) flashes constantly. I'm concerned that PowerTOP caused some sort of hardware problem and damaged my laptop.
Is there a way for me to check what PowerTOP did to my machine?
Is there a way for me to completely revert any changes made by PowerTOP?

Any help would be greatly appreciated.

[PATCH] configure: rework libnl detection and fix libnl-2 case (v2)
by Sergey Senozhatsky
Rework libnl detection.
PKG_CHECK_MODULES macro appends FOO_CFLAGS and FOO_LIBS flags
Example:
LIBNL_CFLAGS = -I/usr/include/libnl3
LIBNL_LIBS = -lnl-genl-3 -lnl-3
while AC_SEARCH_LIBS only prepends -llibrary to LIBS, so AC_SEARCH_LIBS
is not helpful.
Use pkg-config PC file names to search for minimum package versions:
libnl 3.+ -- libnl-3.0.pc
libnl 2.+ -- libnl-2.0.pc
libnl 1.+ -- libnl-1.0.pc
Patch also changes $has_libnl_ver == 0 error message and suppresses
failed PKG_CHECK_MODULES output.
Austin pointed out that libnl-2.0 provide only libnl-2.0.pc pkg-config
file, while libnl-3 has at least 5 of them (for every `so').
This is why we check libnl-3.0.pc and libnl-genl-3.0.pc in libnl-3 case.
Many thanks to Austin Zhang for help.
v2: Namhyung Kim reported that libnl-1.0.pc on Ubuntu is named libnl-1.pc.

Consistent spelling of PowerTOP
by Paul Menzel
Dear PowerTOP folks,
the spelling in the README is PowerTOP. If this is the preferred
spelling – I’d like Powertop better – could this also be used in the
mailing list tag(?), which is currently [Powertop].
Thanks,

[Announcement] PowerTOP Announcement
by Chris Ferron
Hello,
To day(November 1st 2012) marks string freeze for our next release
cycle. Starting now until November 15th, we will only be taking bug
fixes without string changes. The POT file has been updated to
Transfex.net, and I will be pulling translation sever-times over the
next 12 days. On November 12th I will pull translations for the last
time, and only merge Major bugs fixes moving forward.
There is one date change for this release cycle. The community meeting
was set for the November 22nd, but that actually falls on a US holiday.
So the community meeting will be moved back 1 day to November 21st.
Nov 1st (string freeze)
Nov 12th (stop taking all but critical patches)
Nov 15th (release v2.2)
Nov 22nd (community meeting about v2.3)
Community Meetings -
This meeting will be the first where members will contribute to what is
added to PowerTOP's TODO list, discuss what PowerTOP needs for the next
release. Feel free to post topics and start conversation threads prior
to the meeting. We will gather topic that come up.
Meeting Times -
Location Local time Time zone UTC offset
Los Angeles (U.S.A) 8:00:00 AM PST UTC-8
Moscow (Russia) 8:00:00 PM MSK UTC+4
London (UK) 4:00:00 PM GMT UTC

[Powertop ]compiling issue and running issue
by Austin Zhang
Hi,
I am trying to compile powertop on my box: ubuntu 12.04, X86-64.
(1)compiling issue
Here, my system didn’t install libnl-1, but I installed libnl2 (under
/usr/lib) and libnl-3 (under /lib).
Then when ‘./configure’, I got:
checking for LIBNL... no
configure: error: Package requirements (libnl-1) were not met:
No package 'libnl-1' found
so seemed the below logic in configure.ac doesn’t work
……
has_libnl_ver=0
PKG_CHECK_MODULES([LIBNL], [libnl-3.0 libnl-genl-3.0], [
has_libnl_ver=3], [
AC_SEARCH_LIBS([nl_socket_alloc], [nl-3 nl-genl-3], [
has_libnl_ver=3], [
AC_SEARCH_LIBS([nl_socket_alloc], [nl], [
has_libnl_ver=2], [
PKG_CHECK_MODULES([LIBNL], [libnl-1],
[has_libnl_ver=1], [])])])])
……
Then I uninstalled libnl-3, only leave libnl2 there, but no change, the
has_libnl_ver still is 1;
So I did some hacks, to set has_libnl_ver=2 (so got HAVE_LIBNL20 defined),
and remark above logic, then after got Makefile, I manully add -lnl and
-lnl-genl into ./src/Makefile, then I got one powertop linked against my
libnl-2.
But obviously, it is not a good idea to do as this. So is anyone
encountering similar issue there if only have libnl2 or libnl-3, the
original configure.ac in fact doesn’t work?
(2)running issue
With above got powertop (linked against libnl2), after launched the
powertop, I cannot switch to other menus (Idle stats/Freq stats/Device
stats/Tunable), I can only stay at ‘overview’ menu, direction arrows only
move the screen a little left/right.
Is that one known issue?
Thanks.
