No more red LED, YIPPEE!

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

update it, and its great, thx so much, my N900 will never feel thats 'old', :D

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

thanks for the update. flash my device and update it then will create a backup menu backup.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Thnx for the update!
Love to see that people still care their N900

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

how to disable it?

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

bleeding edge drivers don't want to load :confused:

edit: nevermind i was too quick

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Try to modprobe -f. Drivers are compiled agains pre v50 version. lxp must recompile it against released v50 to avoid problems...

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

works fine for me!!

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Please anyone who has not enabled SR, to do a little experimenting with default and dsp profiles and to confirm/not if SR is stable and how is the battery life with SR. Also if you have your own undervolting profile, I will appreciate a comparison between your manually tuned voltages and SR calculated. SR should be rock stable in KP50, but I need a confirmation.

Note:
Have in mind that if you have your own undervolting profile, SR would not make battery life better, at least not much.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

how to enable SR?, i know its so ****in noob question, :sad:

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Just load dsp profile "kernel-config load dsp" if you OC, or default profile "kernel-config load default" if you don't OC. You must be root of course.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

wow yes its stable, but i limits it to 500 900 set, and its still so stable, :)

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

My apologies for this off topic question, but I was just wondering if the N9 actually has SR enabled by default?

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

I have 'ideal' profile on kp50, 500-900MHz clock and vdd1 and vdd2 enabled
It's stable and fast

Batterylife - hmm ... I disconnet from charger 8hours ago and conky showing 50% of battery. Using a lot of wifi, network browsing and jabber. Sometimes easy-debian.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

why i cant upgrade, i tried to uninstall by taping nokia kernell on the menu but the error is "error during uninstallation: could not install nokia kernel."

i tried in x term. "apt-get install kernel-power-bootimg"
got unmet dependencies; kernel-power-modules (=1:2.6.28-10power50) but 1:2.6.28-10power49 is to be installed

:confused:

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

noone willing to teach me how o dissble red led:(

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

KP50 is to be installed, not KP49. Follow instructions as they say. It doesn't get simpler than that.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

what is actually this red led btw?

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

I bet this has been asked before, but what will happen if I install the U-Boot packages AFTER i have kernel power installed? Will I screw up my boot that way?

And, should I use uboot or multiboot, or is it a matter of taste?

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

thank you :D

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

i upgrade before via xterm and i got multiboot so i use "apt-get install kernel-power-bootimg" im on kp49 already.. yep i follow instructions..

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

red camera light..lights up when camera is active..both in photos or video capturing...stil..dont see how to do it...:(

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

What better way to start the week than with a new version of kernel-power!? :D

Upgrade went smooth, and I now have v50 up and runing! Feels great thus far.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

thanks, seems like it boots a bit quicker. we greatly appreciate the hard work you continue to put in pali!

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

after update to v50 i can't open any movie in Maemo player. it writes unsupported media format. can anyone check and confirm... maybe i am not the only one confronting with that problem. Thx

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Pali congrats for your hard work KP50 working very fine for me thanks....

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Not stable for my device yet, did a little testing with default dsp and a modified dsp profile.

I find that SR is not stable for stock mpu clocks above 600hz, voltage seems to be too low for stability even at default DSP clock(430).

eg 720 xx 430 (voltage 45 shown with kernel config)
805 xx 430 ..

both = fail, occasional reboot when locked on each frequency with 90+ % mpu load for above 3-4 minutes.

Tried doing a dirty trick to achieve stability by using dsp boost @ 250,

I do not wish to oc the DSP unnecessarily (I use 850 xx 600 for video recording purpose),so i upped the dsp by 10 mhz to trigger the dsp boost voltages on lower clocks. which will result in the mpu being supplied with more juice.

eg 720 xx 440 (voltage 46 shown with kernel config)
805 xx 440 ...

Still not very stable when the the DSP is loaded with 720p video, it results in a definite reboot after a few minutes of playback.

I would stick with my custom profile till the issue is hopefully sorted.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Anything above 600 MHz for MPU is not stock :)

dsp boost kicks in only when DSP is active, otherwise it is not used

On which profile?

Could you please post both your custom profile and the result of kernel-config show with SR enabled, so I can compare calculated vs manually tuned values.

Also could you confirm(not) that SR is stable for you with "default" profile loaded, i.e. no OC

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

firstly thanks to everyone involved with power v50 cheers (Pali, Freemangordon) :)
I am using dsp profile min @ 500 max @ 805 with sr enabled and had no playback problems and no reboots. battery life seems okay as well :)

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Same here for me , no problems at all . All is running fine , no reboots , battery life OK !

Thx & Cheers :D

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

;) My bad, what i've meant was "oc mpu with stock dsp clocks" is not stable, stupid sentence composition by me :)

I'm aware, thats why i mentioned about 720p video playback issue, because it creates a 60+% mpu load + dsp load. only done for testing purposes and curiosity.


Same modified dsp profile was used was all tests (only the dsp frequencies were changes as mentioned on previous post)


Yes, it seems to be stable.

Custom profile :

up to 600 SR calculated values are fine, though I'm used to supplying a lil more voltage( about 1-2 steps additionally against the SR calculated (real) voltage)

@ OC freqs,

720 45 430 (caused reboot at 43 [= SR calculated voltage])
805 50 430 (causes reboot at 48)
850 52 600 (-used mainly for video recording purposes)
900 54 600 (-used mainly for video recording purposes)

DSP profile (SR) - with flat dsp rate of 430

pls note that the values are as shown on kernel config

250 23 180 - stable
500 36 360 - stable
550 38 400 - stable
600 40 430 - stable
720 45 430 - not stable
805 49 430 - not stable
850 51 430 - not stable
900 xx 430 - reboot withing 2 seconds

*ps : above result are done without touching dsp boost value.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Updated last night by apt-get
No problems at all :)
Video playback is great, same for battery life
Thx Pali, Freemangordon for the update.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

after 3 restarts it started to play movies ... strange. thx its more stable then v49. and now my extra starving profile works :D. just with standby now i can get 7 days :D

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

my profile no reboots even in high load:


MINFREQ=250
MAXFREQ=900
# list of frequency configurations: each "frequency:volt,dsprate"
FREQS="0:10,90 125:21,90 250:22,180 500:29,400 550:31,400 600:33,430 720:41,430 805:45,600 850:46,600 900:49,600 950:53,600 1000:55,600 1100:60,600 1150:69,520"
SMARTREFLEX_VDD1=1
SMARTREFLEX_VDD2=1
GOVERNOR=ondemand
UP_THRESHOLD=95
SAMPLING_RATE=300000
IGNORE_NICE_LOAD=1
POWERSAVE_BIAS=0


it works even with: MAXFREQ=950. I will try SR with over 1000 :). but i do not expect it to work :)

PS.observed something else jabber does not work... keep disconnecting

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

Please post some more details of what needs to be done to install working bleeding edge drivers, ie. download link, untaring, and loading snippets in xterm. Much appreciated.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

FAO: EVERYONE

To disable red LED.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

you will find injection capable drivers for kp50 on the authors website.

If you did not donate yet, please consider doing so.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

finally..someone willing to explain noobs that we have to change a zero for a one:D...tks man!...worked fine.

Re: [Announce] kernel-power stable v50 in Extras-Devel
 

What problem had the led ? I'm asking because the that notification led didn't bother me so far .
