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..

what is actually this red led btw?

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

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....

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

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.

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 :)
