Can someone please write all the process to install this kernel? What do i have to do with those images? How can i flash with dd? I tried flashing only the Kernel, but after the firt time the phone attempt to boot, it reboot in recovery. Can someone please write a full tutorial for noob?i will be needing testers for the g800h kernel, got one already but more is always helpful - eventually got a bootable kernel now so am adding tweaks now
If you had read through the thread u would have mentioned that the kernel wont boot cm13.Can someone please write all the process to install this kernel? What do i have to do with those images? How can i flash with dd? I tried flashing only the Kernel, but after the firt time the phone attempt to boot, it reboot in recovery. Can someone please write a full tutorial for noob?
Write from a s5mini with cm13
Thanks for reading.
Thank you! I have sucessfully flashed.
Now my first experiences .
The kernel works good without any adjustments (no manually change of zzMoove or other things like undervolting).
But unfortunately undervolting does not work. Not with "setCPU", not with "Voltage Control" and not with "CPU Adjuster".
In all cases the phone crashed after applying a undervolting or applying a profile comes from the app.
set CPU shows the different frequencies with voltage. After starting the app 775mV for 200 MHz is shown.
Than I tryed to undervolt for each frequenz only 25mV for the first trial. --> save 750mV in the app. After setting "apply" I noticed, that the table of frequencies/voltages show me 600mV for 200MHz. That is not what I wanted. Where comes the 600mV from?
After applying any modifications or "set for boot" and after booting a freeze comes.
The same with profiles, any adjustmensts due to a freeze.
The same with the other undervolting apps.
With govenor interactive the device crashes immediately after booting and unlocking the screen.
Is threre a undervolting in zzMoove implemented that doesn't work together with undervolting apps?
Does that mean that, a explicitely undervolting app is not necessary und undervoling works via zzMoove?
Why does the interactive governor not work?
Why don't any profiles (set CPU app) work (no undervolting in the profile, only a limiting the max. frequences)?
I have noticed via "CPU spy" app that the device goes in deep sleep mode if I do nothing, but if I unlock the creen and open an app in which I can see the frequence, I see 1000 or 1100 Mhz. In fact either frequence is very down or quite high. Only one app is open and than such a extraordinarily high frequence? Is that normal for the zzMoove?
If zzMoove does not undervolt, is there an other possebility? Or is the manually undervolting of your kernel by the user not possible? Or not necessary? (see question 1, is that includes in yor min. frequence of 200MHz together with zzMoove?)
I know, that it is not possible to give easy answers immediately. But I think, the most users want to try your kernel for saving battery/energy and the are interested in undervolting.
the undervolting is a little bit weird and doesnt work properly, but im working on a better undervolting system for the newer DMPKern i have released recently but undervolting is not critically needed as if the goverenor works correctly the cpu should return to idle quickly and idle is where it uses very little power
Could you maybe post wich voltage is related to wich frequency? I took a look at the kernel file, but unfortunately wasn't capable of extracting the info from it.
Would need it to be able to properly follow the following tutorial http://forum.xda-developers.com/showthread.php?t=3269557. Or does every frequency step include an increase of voltage?
thanks in advance.
btw any news about cm13 build?

But is it a linear scaling or ar there maybe still some less efficient freqs?voltages generally increase with speed. and im reluctant to put a cm13 img out as its designed to use the new LP kernel which also causes issues with touch screen response that im still trying to fix
Exactly! thank u very much! As this one doesn't work for me, thats exactly what i've been looking for

OK Thanks. Without Undervolting there are no advantages for me. Battery life is less than with the StockROM and my configurations. I have about 60 h with Stock Rom and about 50 h with tardis kernel.
spy CPU says for Stock ROM about 93% deep sleep, 5% 400 Mhz 3% for 1000Mhz 2% for other frequencies (default interactive govenor)
spy CPU sya for Tardis Kernel about 93% deep sleep, 6% 1000 and 1100 Mhz, 1% for other frequencies, 200 and 300 Mhz is not used. I thing something goes wrong with the govenors in Tardis Kernel.
So ist is clear, that no better battery life can result.
In Android 5 or 6 I'm not interested. Theoretically there is a better battery life, but in the reality it is not so - says the experiences. CM isn't an alternative, I need the finger scanner for unlocking. New features I don't need. Now I'm trying the Custom Kernel for Android 4.4.2 made by CurtisMJ. Perhaps there are no freezes and perhaps undervolting works or perhaps lower frequencies are really used.
Fixed Samsungs Preinstalled Swap which i borked previous, TW becomes VERY Slow Without it Replaces the swap binary with the one from G800H which allows to set swapfile size Increased the default size from 1GB to 1.5GB
Update To Hyper-Linaro 5.1.1 GCC for performance Increased CPU & GPU Overclocks to 1.6Ghz and 640Mhz respectively other minor changes
