[KERNEL][G800F][EXYNOS] DMPKern/TardisKern G800F LP Edition

[DJ_Steve]

UPDATE 06/03/16
ok eventually a new updates out folks, been trying to get some things fixed before releasing this one

changelog

few small performance tweaks
cpu voltage control enabled(see below)
DT2W active in kernel (disabled by default to save battery)
fading leds enabled

i have created a cm13 zip too now for all those asking, but i have not tested it so if anyone wants to test please let us know what happens. - f2fs should work for /data but again has not been tested

cpu voltage control and DT2W can be used and enabled respectively using the included custom built kernelAuditor app that will be automaticly installed when the zip is flashed. this build is the ONLY build that will work with voltage control and DT2W due to the way the various paths required are set out in non-standard locations.

1.7Ghz overclock is VERY experimental and may not work for you depending on your device

cpu max allowable voltage is 1600mv and lowest is 600mv (those of you who understand undervolting will need to know that)

those of you using my Pac-rom build their will be a new version going up later which has this same kernel baked in

thanks and please report issues.

-------------------------------------------------------

im back again folks, sorry for the delay with this but had some personal things ive been dealing with.

im now proud to announce a new DMPKern Kernel(previously known as TardisKern)

this kernel is designed for samsung 5.1.1 currently (i need to make boot images for cm12/13) and has a lot of new features

changelog

1.7Ghz CPU overclock - by default device is set to 1.4ghz on boot and the higher freqs can be used by using an app such as kernel auditor - use 1.7ghz sparingly as i have not tested it 100%
600mhz GPU Overclock
OTG SUPPORT!!!!
Loads of I/O Schedulers (noop, deadline, cfq, bfq, sio, fifo, zen, vr, fiops, row, sioplus, tripndroid)
Equally Huge List of CPU Schedulers (zzmoove, preservative, conservativex, alucard, darkness, nightmare, wheatley, ondemandplus, dancedance, conservative, ondemand, userspace, powersave, interactive, bioshock, lionheart, performance)
kernel updated to version 3.4.110
F2FS Support baked in for a f2fs formatted /data partition (see below for details)
Notification led Brightness Increased
Ultra-Kernel SamePage Merging(UKSM)
build with Hyper Linaro 5.1 toolchain with graphite enabled for performance increase
Based off the latest samsung LL Kernel sources

ok i know thats a massive changelog but im sure loads of you have heard of F2FS and are wondering just what it is,
https://en.wikipedia.org/wiki/F2FS thats a quick rundown of what F2FS is,

the most important thing is it makes a noticable and quick serious improvement to overall performance for apps. with a f2fs formatted /data partition.

next thing your going to be asking is 'how do i format data to f2fs and will i lose any data'
the simple answer is you need to use a compatible recovery which has f2fs format support(such as newer versions of TWRP), and yes you will lose data but no you wont if you do it correctly.

[strong]But the TWRP Recovery i have doesnt work with F2FS?[/strong]
no the currently released TWRP build for G800F does not support F2FS, BUT..... i am releasing a brand new build of TWRP 3 after this post that does support it. and all you need to do to keep your data is backup the data partition to a microsd in twrp tehn format it as f2fs and restore the backup which does work even though twrp warns it may not..

ok so enough of this babble

download links for kernel:

THIS IS A ODIN IMAGE, DOWNLOAD AND EXTRACT THE ZIP THEN FLASH WITH ODIN

instructions for f2fs conversion will be included in the twrp post

Can't wait for it, I will try it with CM13 when you will release it. But, for now, does it drain more battery than stock kernel? (cause overclocking). Also, is the system stable with it?

seems to be quite stable (cpu overclocking is not active at all times only if it is specifically set, and with the different cpu scheds you can gain battery life without much if any performance hit too)

cm13 boot img ill probably do tomorrow

That's sound good. I will enjoy.

 

[Zear_Shuway]

Still waiting for the cm 13 version.

Still waiting for the cm 13 version.

Me too.

@DJ_Steve What about this kernel for CM13?

 

[DJ_Steve]

im a bit reluctant to make a image for cm13 as this newer samsung kernel seems to cause some touchscreen issues that im still looking into at moment

 

[abdou1241]

Could you watch if at every time you reboot the phone (with this kernel) you have to enable WiFi connection please? Because I don't know why, but at every time I power on my phone, I have to enable again WiFi while it was automatically enabled before

@abdou1241 I also have this problem. It's really annoying connect manually the phone to WI-FI everytime. However I tested the phone with this kernel and did an Antutu Benchmark at 1.7GHz.

I tried to fix it but could not. Have you also a smart manager alert?
Is the phone better with this kernel than cm13 or not?

To be clear, I flashed this Kernel at 6pm(now it is 10:30pm), so I can't say if it's better than CM13. However I'm impressed that whit this kernel it reach the same score and whit 100+ in 3DBench. Yes, I had a Smart Manager Alert. You can disable it rooting your phone, see wich application say this thing and delete it with Root Explorer.

For the wifi issue check /system/build.prop for a line relating to secure storage and set it to false then reboot (will need root and some form of root capable file manager to do this) i think i forgot to add this change wen i made kernel image

I also noticed that there's a bug with the earphone/headphone jack. I inserted my earphone in the audio jack but I didn't hear nothing because the audio was still exit from the rear speaker of the phone.

 

[Andrea224]

Will you fix these problems?

What software are you using as thats usually caused by rom not kernel unless you tried this kernel on a 4.4 rom
