[KERNEL][4.4][KK] franco.Kernel.Plus r203 RC3 (03/15) | discontinued

franco.Kernel +

*Discontinued*

These are my personal franco.Kernel builds with some modifications, explained below.

Things I want to achieve with this mod:

- more battery life
- ~~same~~ more performance as stock
- smooth ui / games
- less heat

Highlights:

Advanced Dynamic Scaling:
The interactive governor will now use different values for up_threshold, timer_rate and min_sample_time for every cpu_core and gpu_idle state. If the gpu is busy, the governor will use values for more performance and if it is idle, it will use conservative settings.

The current values, feel free to suggest other.

Dynamic Touchboost:
The touch boost is only active if something is rendered on the screen, that means the boost will pause as long as there is no movement, but it will resume when it is actually necessary. It will double the actual cpu load and calculate the frequency, the maximum is input_boost_freq. This aggressive calculation offers a smooth ui, but it can also save battery, because you will often don't need input_boost_freq when the screen is touched.

New Hotplug Solution:
Instead of linking core0 to core2 and core1 to core3, all cores a controlled separately. This should prevent an excessive hopping up and downwards. The load is calculated with all active cores to get the performance we actually need.
After some time (if 2 core touchboost is active) and not touching the screen, only 1 core will stay online to save a bit more battery.
It will use different up and down thresholds for each gpu_idle and cpu core state.

Smooth thermal throttling:
When the temperature hits the threshold, the frequencies won't be limited immediately but scaled down step by step to prevent lagspikes from jumping between 1,5 and 1GHz (if the current temperature allows it). This mod is absolutely not made for benchmarks because my solution is as agressive as the original one. There are other good kernels to melt your device.

Hit thanks if you like it.

Buy Franco's app or just a coffee for me.

I'm testing all my builds and use them daily, but I am not responsible for any kind of damage on your device.

Which version should I choose?
- JWR for stock 4.3
- JSS for JLS roms
- JSS-CAF for cm 10.2
- builds >= r194 are for Android 4.4 Kitkat (KRT)
- builds >= r198 are for Android 4.4.1 and 4.4.2 Kitkat (KOT)
- KRT is compatible with KOT and vice versa
- cm 11 is not compatible

Same as Franco or, if I have to do that, not jet.

Are kernel wake lock stats available as well ?

good idea, I will readd them

KiD3991 · Aug 21, 2013

Awesome. More toys!

And I like what the first thing said, more battery life. Still searching for the ROM that can give me 8 hours SOT.

HAHA!! Aren't we all!!

At 162mhz the lowest I could UV is 650. So remove set at both if you wish to try lower

You mean 192mhz?
Eh, since my CPU binning is at nominal only, I dare not UV more than 100 though.

And afaik, UV excessively does not actually help save battery, instead it uses more power. Somebody made a test, its somewhere in XDA.

I can reach 7 hour SOT in 4.2.2, I just lost that screenshot somewhere, in 4.3 I have yet to find it(5 hour SOT is not hard).

BoOsT · Aug 21, 2013

Shows 162. Undervolting your device reduces the power the processor receives to only what it needs to run. If you don't suffer any I'll effects in performance I don't see how u would lose battery. However, I'm a try it and see how it works kinda guy.

Is this working with touch control? Modules enabled?

thanks for your great job! I have tried the kernel and my phone runned smoothly! :laugh:

Does UV excessively not actually help save battery? I am interest in this. Could you please give me the link you montioned? Thanks a lot!

It doesn't... It helps other things like heat which would help your battery health and lifespan on the long run..

This guy is right.

It keeps heat down, but might result in higher battery consumption in some cases.
