[YP-G70][Kernel][3.0.8][LiveOC] KKernel R2.1 by KOala888

Ok, please respect my time spend on that kernel and read at least those few opening posts and last pages of topic.

Many users reported that overclocking doesn't work for them, they got SODs etc. most probably because of gpu overclocking. So I present you a kernel with LiveOC feature that should be good for every user.

1. Main features (more in changelogs and on mine git)

* LiveOC
* Fastcharge
* CustomVoltage
* 441mb of RAM
* 400,800,1000,1100,1200,1300,1400 frequency steps with stock gpu&bus speed
* BFS
* Lowmemorykiller from 3.4
* Frandom
* 3.0.8
* Fsync disabled
* Lowered screen minimum brightness (I hope so that this is our hardware limit)
* default SIO and conservative
* opitmal readahead
* mine touchscreen values
* wifi works at normal speed when device is locked
* battery is charged to its 100%
* Touchscreen undervolted 20%
* Maaany other fixes and small features



2. Tunables

For managing those features you are supposed to use apk like NSTools or any other, but that one is highly recomennded



LiveOC

I implemented it so everybody can overclock as he wants to, total personalization and freedom of choice. And possibility to squeeze maximum performance.

LiveOC simply overclocks CHOOSED cpu frequencies by a % choosed by YOU, user.
As the gpu&bus frequency is simply cpu frequency divided by a number, it also is overclocked by choosed %.
Unfotunatelly cpu frequency and gpu&bus frequency are linked so choosed % affect both of them.
As I said, you can also choose which frequencies to overclock which is great facility.]
You won't probably be able to overclock more than 127% because of our BUS which can't achieve such a frequency (most devices)

For example, you choosed minimum frequency affected by LiveOC as 1300mHz and maximum as 1400mHz.
You set LiveOC % to 110., then:
1,1*1300 ==> 1430mHz
1,1*1400 ==> 1540mHz
1,1*200 ==> 220mHz - gpu&bus frequency for both of the frequencies

Now you probably think: Ok, I can overclock even to 1,7gHz but my device will reboot for sure because of too low voltages! That is why I also implemented CustomVoltage. Although when you overclock it slightly then you possibly won't have to adjust voltages.

*WARNING*
Some frequencies seem to not like liveoc, for me it is 1300mhz. Also some liveoc values can be laggy, use different then.



CustomVoltage

CustomVoltage allows to set you custom voltage for both cpu and gpu&bus.
Perfect solution for undervolting and overvolting when using liveOC
ARM voltage - voltage given to CPU
INT voltage - voltage given to GPU&BUS



Fastcharge

Fastcharge make charging via USB as fast as via normal A/C charger
You can simply turn it on and off whenever you like.



Minimum Brightness

Now your device can be even dimmer when using it at night.

*WARNING* You have to use RootDim apk for this thing. Lowering brightness via setting or on statusbar would require rom modification

I highly recommend seting up a custom tile, you choose Rootdim night1 and for example system icon "cloud".
Then you open RootDim, set your brightness to 1 and longpress Night1 button.
Voilla! You have a custom tile that sets your brightness to 1
I hope that it set brightness to our hardware minimum.
I also recommend switching off keys backlight by a script or manual permissions change

CHANGELOG

7th July 2013 - Release 2.1
*3.0.85
*Updated GPU drivers
*less debugging and ram dedicated to it
*new wifi drivers? not sure if we use same as aries
*some fixes to SLUB
*KSM and VM tuned
*async I/O improved

18th June 2013 - Release 2
*3.0.82
*Build with A8 cortex optimized toolchain
*Some optimization for flags - feels smoother
*Finally found my dream governor - intellidemand, seems to be perfect for my idea of the kernel
*Update zip contains script turning off our keys backlight! From now with the minimum brightness mod you can enjoy using player at night

31th May 2013 - Release 1
*unnecessary governors removed & conservative - default - can cause laggy UI - still have to find proper governor
*even dimmer screen

26th May 2013 - Beta 2
*linux 3.0.8
*removed 100&200mhz frequencies to eliminate SODs
*Battery is charged to its 100%

19th May 2013 - Beta 1
*initial release

Download is up so please enjoy

LiveOC helps to squeeze 100% from EVERY device

The only one supported. Old are totally aborted. I just had to start from a scratch again.

I hope that youtube and kerys will work for usa, not sure

ok so far i been testing international kernel on latest iurnait's cm10.1 , tried vice city on medium graphics and it works pretty smooth, the touchscreen tweaks makes it really easy to control, cpu freq 100mhz-1400mhz, performance as governor and SIO as scheduler are just working great for heavy usage, best performance on my galaxy player so far, good job :good:

Thank you, you should try liveoc for sure Maybe later when I will add more detailed instructions.

android1234567 said:

@KOala888 you should add instructions on how to configure liveOC so far Ezekeel's liveOC is pretty interesting but it doesn't scale up voltage and it doesn't OC the GPU well

BTW you should add credit for Ezekeel in the OP because he made the liveOC

1 last thing: there's no UKSM in the kernel

There are some accualy
Also, I did everything in hurry, and as you can see I have written that I have to make better opening post in future, so don;t worry everything will be added, like credits But thank you.

Also it isn't exacly ezekeel's liveoc I think. Why it doesn't OC gpu well? Stratosk has voltages scallable, but it is very individual feature. Most often you overclock 1-2 frequencies, not all of them, so not too much to adjust

I will add suggested configurations and voltages in future. I like liveoc because you can get literally maximum performance from overclocking here.

About UKSM, not sure, git doesn't match my HDD repo to well ;c

Well I wouldn't say it is anything related to liveoc overclocking gpu in a bad way. It can be voltage, other kernel changes, toolchain (which I will change too), anything

I prefer hardcoded overclocking, but liveoc gives same performance and you can push it to the limits

And I don't need it to be the best in benchs, I want it to be universal. For me it is the best anyway

In epic citadel I got 41 fps

Nope. If you overclock it to 120% then every affected frequency will stay at 120% unless you change it to 100%
Feel free to ask

And about gingerbread, I don't use it. It literally sucks comparing to 4.2.x
So sorry but I can't. Hardware acceleration and many useful features do the thing.

But maybe in future, as an experiment, to see whether it isn't faster while gaming. I already had gb kernel some time ago but discraded.

But I included tunable selective liveoc too. So you can choose frequencies to overclock
Than you for help android1234567, btw do you use it? how is it?

Goodnight guys

I tested the kernel and it works well

How do I use the selective overclock?

In NSTools in cpu card you have values like OC target low and OC taget high. If you choose for example 800 and 1200 then every frequency from 800 to 1200 will be overclocked

Man, these 5.0 kernels are just amazing. The ram, OC, and everything. I'm really hoping that we'll see kernels with these features on the 4.0 sometime soon!

I'm curious, how much of a battery improvement does the LCD UV make? On the 4.0, the display eats tons of battery, tons and tons more than anything else. Wondering if we brought that to the 4.0 that it might fix that issue.

Hm, just take from batterystats the % of battery that your LCD takes and multiply it by 0,8 Also, you have other display

See first post, set minimum frequency to 400mhz until I won't fix it

I never used it. If I foxed it then by accident
