There is 19+MB folder in /usr/src/ Is it required or not (because folder name is src). Don't want to delete it without confirmation.

Running kp49 without issue. Don't forget to do your apt-get upgrade folks.

Don't forget to *not* use apt-get upgrade, as far as You want to keep any custom-installed packages (i.e. 720p video recording/playback from freemangordon). Just update manually, what is needed to be updated.

You can also use the dpkg --set-selections for holding packages, e.g: (as root)
dpkg --set-selections << EOF
camera-ui hold
libgdigicam-gst-camerabin0 hold
libgdigicam0 hold
EOF

hi guys,

some people have big troubles with kernel-power-settings

with kp-settings three processes stay always ON ( per, core, iva2 )
so the battery drains very fast ( 8 hours from 100%-0% )

You will notice while the results are not that significantly different, there is a shitload more DMA activity and IRQing going on when kp-settings is installed. While the CPU is not hammering some hardware on the N900 is. Notice the extra 100% ONs in the power domain table for with kp-settings.

There is an ancient bug in kp-settings. I had issues with kp-settings since version 26. I never figured out why it caused all these wake ups I just know in some circumstances it does.

have someone an idea what can be wrong with the kernel-power-settings? i would really like to use kp-settings, maybe someone can fix it?

with kp-settings:

Code:
C#      | Ratio  | Avg/dura | Frequency | Ratio
--------+--------+----------+-----------+--------+
     C0 |   0.2% |          |  1150 MHz |   nan% |
     C1 |   0.0% |    0.3ms | 
     C2 |   3.3% |    9.4ms | 
     C3 |   4.2% |  104.3ms | 
     C4 |  92.3% | 1730.5ms |

Maybe not 100 percent related, but those aren't Your words - You just copied and pasted parts of vi_ posts from other thread. While it does not invalidate report itself, I think it's better (and more fair), to mark quotations with proper credits, especially, that You're mixing it with Your own findings and requests in-between. And it make people think really *You* got issues dating from kp-settings 26 (in fact, it seems that You haven't had N900 then), which may result in directing questions to You, that should end up in vi_'s "box". Not to mention using language and terms quite out of line for Your actual knowledge/understanding of what is going on here. No offense in this last sentence, just preserving "quality and assurance" of discussion here.

muhahah, estel, you are the man!!

it's correct, that all the credits from my posting #2397 in this thread are going to vi_, we have discussed the issue in an other thread within 40! replies
why reinvent the wheel? i hope and i think so, that vi_ is not angry about my procceding!

without vi_ i had not come to the idea, that kp-settings fu*k my battery up!
it's fact that kp-settings cause massive problems, and the question is why?

screenshot with kp-settings from my n900:



screenshot without kp-settings from my n900:

After a few days of tests and reboots i think i have found something....

There are many posts of people using kp49 without any battery issue...

In the meanwhile, there are many others asking why kp49 drains the battery a lot faster if compared to kp48...

Observing my N900 i have found both of the situations, BUT.... WHEN?

When the battery drains fast, the cpu is always at full clock or remains locked on an high clock profile never changing from that value also if the is apparently there is no load.
Very often, also rebooting, the situation does not change.

In other situations, same phone, same profile (usually i use the "default" one) there is almost no drain and the batteryeye draws a orizontal line.

So what changes?

Look at dmesg... if you can find a
"DSPTrace DSP MMU FAULT "
the battery drain will be like a waterfall!!!!

Many times, also during the boot process you can find that error.
If you start with that, you can be sure, say bye bye to your battery....

If you start the phone without errors, and the battery drain is ok, if while playing media file or running something a DSP FAULT message appears on dmesg, from that moment the cpu will remain locked at an high clock and the battery drain will go to the stars!

Any suggestion or confirm to my teory is welcome!



Thanks to all for this great comunity work and forum!
