Battery source in /mediatek/custom/"project-name"/*
kernel/battery.
There is some calibration value, max capacity, sensor type
NTC/PTC, battery type.
I think better you find other kernel source that have
exactly same battery capacity with your phone, then
change the your battery files, it is easier then change the
whole value by your self.

Hi.

Yes i know, if you check my last commit on git you'll see i changed some values there.

But regarding battery settings/configs, there's also the drivers power API on ..mediatek/platform/mt6577 .... Etc.


Also concerning this device, there's no source that fits it, its been an headache from the beginning
This ZTE uses a lot of custom drivers. / changes on the regular vanilla ones.
But thanks anyway. ;)

Regards

HI

The day has come, Fisrt STABLE release is here ;)


Changelog Stable v1.0 (April 06 2014)

  • Fix whrong Battery Percentage being displayed ( % )
  • Fix whrong Battery sensor temperatures being displayed
  • VM_MAX_READAHEAD is now set to 1024kbytes
  • Tweak vm dirty ratios (thanks to varun.chitre15)
  • Compile vfp with neon (thanks to varun.chitre15)

Also now there's an new compiled m4u module (kernel module)



HOW To Flash:
There's NO NEED to wipe data or cache / dalvik
JUST flash the kernel on recovery ;)


Just choose the correct .zip for your JellyBean version


Just an small note:
(About why both kernels have different build hours)
- They have the same commits/patchs/improvements.
- The reason is becouse i added some initial functions to fix the camera on JB 4.2, but this was crashing the camera on JB 4.1, so i recompiled the kernel again for the JB 4.1 adding the correct camera values ;)

This kernel was tested, and working:

JB4.1 ROMS:


  • Bruno's Stock 4.1.1
  • MuseOS 4.1.1

JB4.2.2 ROMS:


  • My Stock Rom 4.2.2

Good work, hope more updates! There is possibility of varying the frequency of the processor when in charging the battery so that it is not full and shorten the charging time?

Regards.

Yes
That should work just fine, changing into an powersaver / conservative Governor.

Until now, there are some pretty good governors that boosts an little the overall phone performance.
IO schedulers also, I've been testing the SIO scheduler and its rather good.

How those governors are activated? To me I do not appear, nor the cpu governor switcher, or the no frills ...:what:

Does it mean, that now we can port CyanogenMod or other AOSP ROM's??
Or compile kernel with exFAT (exFAT-nofuse project) filesystem support or standalone module?

PS: And where is download links??? I cant find anything in "DEVDV Download section"!!!

UPDATES:

- I have applied more than 500 commits (patches) to the kernel.
- Kernel source is now updated to 3.4.5. (Kernel common)
- A lot of new improvements / features where added

TO do:

Due to the new commits, I need to fix some things on source code, that got broken.

Don't ask for ETA please I spent a lot of time this week updating the kernel (check the commits on my github ... )


Also I'm currently testing overcloking ;)
Its still a bit unstable and needs more work, OC on an Mediatek was achieved by an different method than the usual for other SoC's.


Will keep you up to date
Best Regards ;)

Some people really cant read, and cant follow my rules...

Please re-read my "GPL Compliance" paragraph.

I said not to include my kernel in your own cooked ROM and released it to the general public.
Instead add an link to this thread.

As so, this thread is now closed.

Learn to respect other people's work.

    Open Sourcing Mediatek - ZTE v970 ; SoC MT6577​



    Being owner of an Mediatek device, means (most of the times) not having the sourcecode published by the Official vendor.

    ZTE never published full ICS sources (they only gave us incompleted, and unbuildable sources).
    Furthermore, we never had JB 3.4.x Kernel sources.

    Well this is xda after all, meaning we can accomplish pretty much everything ;)

    This is an fully Custom Kernel Source.​


    ​

    ### For JellyBean 4.1 / JellyBean 4.2 Roms ONLY ###
    --> For the new KitKat Build The Kernel is already included on the Rom, and Kernel Updates will be on that thread    ​


    Hello Guys ! ;)

    In this thread you will find my custom Kernel for the ZTE v970 / v970m / Smart a18 (Portuguese Single-SIM version)
    Please be sure to read (and re-read) to avoid unnecessary questions.

    Kernel 3.4.11
    GitHub Repo


    I do respect the GPL, but using someone else's work without proper credits is just LACK OF RESPECT.

    • The inclusion of this kernel in your ROMS is NOT allowed.
    • Instead add a link to my kernel thread as a recommendation on your thread.


    I Don't support KANGS!

    So please Show some respect, when using my commits, as well as the commits i added from other Dev's (with proper credits/ git authorization)

    Fail to comply and i will drop this project

    How to Flash
    On recovery: (No need to wipe anything)

    Just Flash the desired Kernel version.

    It wont afect the rom, or your userdata.

    But Just in case, make an full backup before flash

    Download
    Kernel Download is now available in the XDA: DEVDB "Download" Section.



    F.A.Q. :

    How can I change I/O Schedulers and Governors?
    You can use the No-frills CPU Control APP from the PlayStore to switch bettwen then.

    What's the Best Governor / I/O Scheduler?
    Depends on your needs (Performance; Powersaving; etc)
    An good resource, check this This Thread or Just Google it ...

    How to Overclock my Device?
    Download the attached app (THANKS bindassdost):
    1: Add BBoost Game Mode widget to homescreen
    2: The app widget behaves as toggle button to switch between stock and overclock (Overclock don't survive reboot)
    Don't open the BBoostManager app, what you will be using its his WIDGET.
