Re: [Announce] kernel-power stable v49 in Extras-Devel
 

surely people would have noticed this through conky? mine clocks up and down fine.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Sorry, in my opinion conky eats too much cpu to be used to debug a cpu clock and battery drain issue.. but yes in anyway it may be a reference to understand if the cpu remains alway at maximum.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Hi,

I found that a battery drain appeared more often after using Media Player, but cannot really put a foot on it... will watch out for the message and feed back.

batter graph in the attached file. Using media server was around 13.15 at teh end of the graph. not much usage before and after (some emails, no calls, no surfing). Will post another battery graph after an hour to see if the decline continues.

Hope that helps in identifying the problem.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

@JanW

please, look at the cpu clock behavior.
Is it variable or blocked on some frequency?

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Just an update, see attachement. The battery has drained quite a lot. I left the device in standby.

Today X-Fade tryed to do something... But you can see that it is still not fixed...

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

I do not have these errors in kernel output after using media player. Can you be more specific about what stuff you have installed?

720p stuff?
kernel version?
experimental camera-ui2?
etc...

Re: [Announce] kernel-power unstable v49
 

Unfortunately the phone still reboots on stock speed and settings with SR on. About 4-5 days inbetween reboots. The phone is idle when it happens with no apps in the background and the screen is off and locked.

I'm going back to the stock Nokia kernel.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

ive noticed some battery drain when locking the phone and forgeting about it and about an hour later i unlock it and its droped about 30% but then otherdays the battery barely loses any charge maby 1%

the only thing i can remember is i have just manually disconected from wifi or mobile internet then locked the phone straight away but cant reproduce it

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

First off all make sure you have 'pastebinit' installed (apt-get install pastebinit)

1. Put device in offline mode.
2. Turn off device.
3. Remove battery.
4. Insert battery.
5. Power on.
6. Stay in offline mode.
7. Wait 4 minutes (for device to settle).
8. Run this code as root:

9. Immediately lock the screen and leave it for 5 minutes.
10. Connect to the internet and type in:

11. Paste URL here.

12. remove kernel-power-settings and do it all over again without KP settings (from step 1).

13. Then enter this:

14. paste URLs here.

15. Also list any hacks/patch/craps you may have installed.

Re: [Announce] kernel-power unstable v49
 

Does your phone random reboot without SR (either kernel)?

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

@vi_
thanks for your suggestions, tomorrow i will try.
My situation is kp49 + dsp libs for 720p and camera-ui hd enabled (using kernel default profile).
No other patches or mods.
I installed dsp libs and camera-ui after the first issues with the DSP FAULTS but nothing has changed.

NOW...
Since about 7 hours i disabled VDD1 setting it to zero into the default profile.
Until now ...no battery drain, media player working and no dsp errors!!!

It would be great if someone with the same problem could apply that change to confirm or not if it is a solution....

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Does that suggest SR is still a kind of folklore? Some devices can take it while some cannot? Perhaps some kind of 'fudge factor' set in /sys/power/ which is added to SR value. i.e. SR value+fudge factor (1, 2, 3, etc) to accommodate individual pieces of hardware?

We need results in order to conclude anything.

Hi what is the up to date way to use uboot with kernel 49 stable ?

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

I've problem installing boot image for multiboot from Application Manager. It says breaks the 3rd party package policy.
Since I installed nitdroid, it left me unable to boot into v49.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

In case it matters. After I bought the N900 about one year ago I read everything there was about Maemo and the N900. At that point my general conclusion regarding SR was "stay away from it".

That's what I've done. No VDD1, no VDD2. My battery behaves consistently good (up to 5 days with little use). KP47, LV, 805Mhz max and no CSSU or crap-patches.

For all I care, kernel support as well as hardware itself is buggy when it comes to SmartReflex.

I know it's unsatisfying (not being able to fix a bug), but I would suggest forgetting about SmartReflex. Perhaps this would open more "resources" to fix and further develop compcache.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

eh? Since kp49 smart reflex hoons like a boss. These battery drain issues are not SR related. I am just interested in your case as you seem to be a unique one.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Well, what some devices cannot take is DSP overclocking and SR enabled. More precisely:

dsp kernel profile sets DSP clock to be 600 for MPU 805. Some devices cannot handle that. The solution is to move DSP overclocking to higher MPU frequencies, for example: (720,480) (805,560) (850,600) , where first comes MPU frequency, second - DSP. And maybe some devices cannot handle 600 for DSP at all or at least not bellow MPU@900. Nothing to be done here.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

With my device, (2204) i confirm that all the problems are solved with vdd1=0 and the default profile.(no overclock)
NO instability, no problems recording/playing video, perfectly smooth and no battery drain.
As soon as i enable vdd1, i cannot play any video, cannot record, many dsp faults and battery drain...

Going back and setting vdd1=1 all the issues start again...

So, same phone, same apps, same clock profile.... only one bit of difference between one working phone and one apparently faulty device.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

@xes,

There you go. Now enjoy your working phone!

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Well, that is strange, seems my SR re-calculations will need an adjustment for the next KP. In that regard could you please post your "/sys/power/efuse_vdd1" values, along with voltages SR calculates when enabled.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Same here, as i previously posted, my device too (2104) cant pay video steadily with SR even for stock clocks, SD video just quits while playing back.

Also i didn't notice any improvement on battery life for the past couple of weeks with SR on, seemed it drained faster.

SR is not working for some devices for sure, so I'm back to using without SR until you hopefully update with new calibrations...etc

The issue is severe when battery level is low (close to emply) video just don't play for more than a few seconds or don't play at all.

I'm not too sure how power regulators are programmed/designed and whether there any load line calibration in place, instability might be caused because of a too high v drop when the mpu and dsp is loaded, i suspect this since the volts supplied is already very low.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Turning on SRVDD1 with kp49 from the repos makes DSP bomb out on undervoltage. Doesn't reboot the system though, so I'll give it that.

Oh well, it seems that my N900 just can't take SRVDD1.

Is not it possible to adapt NTFS-3G or any of the modules that support modules on today in the distributions?

NTFS-3G

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Hi,
I don't know if this is the correct thread, but as there were some battery drain problems in this thread before, I decided to post it here first.

This Friday evening, I charged my phone completely.
I then had to do a 999 call during the night at 2. Afterwards, I changed my profile to General in case they wanted to call me back.

When I woke up the next morning, my battery was drained.
Batterygraph showed a constant CPU usage.
Top showed the process pulseaudio to consume app. 13% of CPU.

I obviously cannot reproduce this (fake 999 calls are not really what I want to do), just to note it down somewhere so somebody can look into it.

Regards,
Jan

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

To be honest, I don't belive in *any* device not being able to handle DSP 600 at all or DSP 600 @ 805 MPU. IT's just a matter of voltage. If disabling vdd1 and using sane voltage result in DSP 600 @ MPU 805 (or even lower, lol) working great, it mean that SR vdd1 calculates too low voltage for such MPU and DSP, yep?

From my subjective perspective, power saving *is* present, with properly functional (= no errors) vdd1 - and I'm think I'm quite prone to placebo effect (I was very skeptical about so-called power saving with SR before freemangordon recalculated them). But, this isn't any dramatic power saving, so I think it's better to take higher voltage reserve, and make it working reliably on majority of devices in any situation, instead of trying to achieve best power-saving.

BTW, isn't there any way of making this value configurable for power-power-powder user, that are sure their devices can take it without errors? Of course I mean SR calculation values. That would allow us to set quite high default ones, still allowing willing people to adjust them.

/Estel

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

@Estel, I am thinking of a better way to do recalculations of SR calibrations, the way it is done now is not the optimal. Otherwise there should be no problem to export some "SR adjustment" to userspace through sysfs.

And of course for those who has their devices already undervolted to maximum there won't be "magical" ;) battery saving, yet still there are (1-2 hours of heavy usage that is what I see here). And have in mind that biggest consumer is screen, not DSP/MPU, so we are near the maximum possible battery saving that could be achieved

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

I was reluctant to upgrade from kp48 to kp49 but man, I'm sure glad I did.

I save around 30% battery usage with both vdd 1 and vdd 2 enabled (default profile 250-600) with heavy usage: online mode, watching videos with cutetube, music, email, emulation and mid brightness (3 bars).

My battery was averaging 5 - 6 hours with heavy usage (watching videos non stop) but now my battery averages 8 - 10 hours, again, watching videos non stop.

That's a huge bonus for me, so thanks everyone involved with this kernel, I'm gonna enjoy my n900 for longer now.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

Uhm. Just a simple question. I've seen kp49 around for a while, but please don't tell me it uses SR by default? I know that it causes my device to reboot as soon as I enable it.
If it's not enabled, I'll gladly upgrade as there seems to be many useful things here. :)
Btw, I read there is framebuffer console or something like that..? Would it be possible to boot into a console with that, except for doing those hacks with the bootmenu/multiboot one?

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

The new kernel-power settings which kp49 needs turns on SR by default.

Re: [Announce] kernel-power stable v49 in Extras-Devel
 

SR is enabled by default, but don't worry its now very stable on mpu side, your phone will not reboot ;) , you can try playing video content and see the they are stable, if so you can leave it on or disable otherwise.
