Sources are on my PC but its not with me currently, as I had mentioned before.
Having a lot of traveling since last week.

Anyways I will update them as soon as I return back.

I am ready to help. Is this for 3.0.x Kernel?

Hello Napstar,

I needed some help with 2 patch

XDA_Bam said:
I second that. It would be great if you could bring your GitHub up to date so we can have a look at your patches. I would appreciate it and am eager to apply one or two of them myself

Ehm, can u napstar when u have time ( or doomlord but i think the v14 source is on napstar pc ) push and update github repo?

thanks a lot

EDIT: For voltage sysfs, if it's respect standard you can use Voltage Control app ^^

Vdd table will reset after reboot only if you have not used any app which has "set on boot" option.

If you are varying VDD using terminal emulator or through adb it will reset.

I can't comment on wifi as I am using cm9 right now

Another question on the vdd sysfs.
When we change it, will it be reset after reboot?
What I'm worrying is when we set a voltage value which the phone cannot handle, it will hang or anything bad happen right?
so if the value is still won't reset even after reboot, it will be a bad disaster to our phone.

Another question to confirm about the wifi error.
The wifi error problem will be triggered by what?
Saw some post earlier, it said when you keep min 300mhz, the wifi error won't happen.
How about max 1300mhz or above?
Because I faced wifi error problem before in previous version of kernel with min 300mhz max 1250mhz.

I suggest using adb shell or terminal emulator and follow these instructions:

[ Note to change vdd levels ]
To check VDD table

Code:

  cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

To change voltage level of a CPU freq, let's say for 900Mhz change of voltage from 1000000 to 1050000

Code:

  echo 900000 1050000 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

I had problems using app though I have used standard SVS format.

How to check/use vdd sysfs?? Dont have any idea about this. Tried to google but gone over my head I think this is the reason why many people have not reported yet any feedback.

Im using the latest v14 version without the vdd thing,i have no issues with wifi,with the stock or overclocked frequencies not sure about underclocking.

I know its a very silly question but still I want to ask u that whats the purpose of changing voltage level of any frequency?? Say for example we change frequency to minimum to save save battery or increase frequency to improve the smoothness of phone functions.

Lowering the frequency to save battery means less performance, but it you undervolt your cpu it will save battery but have the same performance. Of course that alone won't do very much, but if you lower the voltages for every frequency to a stable minimum and cut off your maximum cpu freqency you can save more power and that all the time.

simple word, lower voltage drain with overclock.

Thanks, I have a suggestion, Don't you think too many Governers are simple bloating the kernel?

Yes, but it's not influence at all, governor are 100-200kb sized each, nothing to hard, i think he include a lot governor because everyone has a favourite governor ^^

my kernel ( wip only on github and not released for now ) , include only high personalized and rewrited for our device lulzactiveV2 and conservative governor tuned for battery from kernel 3.0 ^^

if i'm not wrong:

if dhiru lower its voltage, the kernel is more unstable ^^

@Napstar, DooMLoRD
I tested latest version UC-Kernel v14, cwm cannot restore backup (task android secure file), all before task restore succ..
I revert back to V9 (3009 without full touch) and restore backup work fine....

not really, in my understanding, stablility, depend on the HW.
if you feeding enough power to the HW, it will be stable, once HW stable, SW also stable(provided the SW is atually bugfree)
however, in stock kernel, they set the "enough" value at the standard "safe value",
which is more than enough. so, some phone having over heat even on stock.

so, in the perfection value, you phone will be stable and cool. therefore, for the usage of UV, is to save battery power so can getting long up time but without sacrified the stablity of the phone.but every HW may having different break point, so that why it need to fine tune

Of course it changes from phone to phone, but in in general higher voltages (as in closer to the stock value) provide better stability at the expense of battery

Anybody observed that when phone is in deep mode & if we receive a call then scrren take nearly 4-5 seconds to show actual scrren where we can receive call by slide to answer buttopn on screen??? Tested this 5-6 times
Info about my kernel & rom configuraion can be seen in my signature.

of course, there re a limit and a perfect value, hw may having different voltage limit support, like overclock, but example:
1.40V -> 1.2 Ghz is fully stable for me
1.38V -> 1.2 Ghz is stable but sometimes crash ^^

It is normal. Usually restore the backup on the kernel you made the backup with

guys, i change my rom to stock xxkpq no kernel all stock but still my phone keeps on restarting, then flash it again on stock xxkpu no kernel all stock but still my phone keeps on restarting, any advice what to do? i flash using odin on my laptop,

note: i dont know where to post

My friend. Go to general section. You'll find your answers there.

@bscraze
Bro, i made backup with v14 kernel, this kernel cannot restore android secure task......different kernel like v9 restore this backup....
