duki994 Kernel for Stock TouchWiz MM ROMs
Development stopped. I don't have device anymore
This is for MM only!!! For LP go to duki994 LP kernel thread
LP kernel thread
It's based on official Samsung CPE6 sources for Marshmallow firmware.
Important note:
This kernel should work on any custom ROM that is stock lollipop based and is based on stock CPE6 source
Features:
* Wolfson Audio control adapted to G900H implementation (thanks to @AndreiLux)
* Charge control by me (@duki994)
* CPU voltage control for both A7 and A15 cluster (thanks to @AndreiLux)
* Exposed all OPP voltage controls (thanks to @AndreiLux)
* LED fading control (thanks to @AndreiLux)
* Powersuspend v1.7 by @faux123 and @Yank555
* MM and FS powersuspend mods ported from @dorimanx's LG G2 kernel
* SCHED code fixes
* SCHED: HMP thresholds changed and new patches implemented
* OF code updated --> better/faster reading of DTS and faster operation
* Many changes related to ARM instruction code and lowlevel ARM core management
* Enabled NEON mode in kernel with full VFPV4 support
* Added new SHA256 , SHA512, SHA1, ASH2 and AES NEON accelerated algortihms - now blazing fast
* WiFi fixes
* NET updates
* LMK updated and added new feature: Adaptive LMK --> better multitasking
* Enabled all TCP congestion protocols and set Westwood as default (best wireless performance)
* Wakelock disabler: You can disable some common Samsung wakelocks in Synapse "Misc" tab if some of them are draining your battery
* Fully configurable in Synapse application (download from Google Play)
For kernel configuration use Synapse
Download from Google Play.

/* Important note to other devs */
You cannot include this kernel in your ROMs. I can't be responsible if anything goes wrong, I can't help with any issues without knowing kernel version and users should be routed to this thread if they want this kernel, or if you recommend it. I think that it's best to separately view custom ROM and custom Kernel, so each dev (ROM or Kernel one) can work on bugs/features and make it as compatible as it can.
However, you can add this thread link and mention me in your thread, as so people would know where to ask if kernel problem arises. I will do the same for you
Warranty void
By flashing this kernel you will void your warranty. I'm not responsible if you brick your device, or if someone starts nuclear war.
Note:
Don't change voltages on "Busses" tab if you don't know what you are doing. It can reboot your phone if your memory controllers, ISP or MMC controllers that can't handle low voltage.
If someone happens to have bug with WiFi saved password being lost every reboot, here is fix:
WiFi pasword resetting fix:
Code:
1. open your build.prop file
2. find line ro.securestorage.support
3. change it from true to false (if not already false)
This line being on true WILL make your WiFi forget password each reboot. This is due to Samsung's rooting restriction and other Samsung specific workarounds to stop rooting and flashing. Any custom ROM probably has this line changed to false.

SuperSU problem fix:
After each kernel installation you'll need to reinstall SuperSU from Play Store or from apk.
I'm trying to solve this problem currently.
Root and busybox work as intended. Problem is only with SuperSU app.

Changelog:
Version 1.9 BETA
* MM updates
* IRQ and ARM GIC (Generic Interrupt Controller) updates
* CPUFREQ critical performance and battery saving updates for big.LITTLE architecture
* ARM arch specific updates and workaround for various bugs from Linaro LSK 3.10.x tree and ARM devs
* EXT4 and FS updates for better performance and less CPU usage. Also some code cleanups.
* NET updates
* Silenced mDNIe dmesg hooks. Not needed now as mDNIe control is working as it should.
* RCU NOCB ALL for better softirq workings in kernel (should provide boost to moderate usage)
Version 1.8
* Added mDNIe control (display color interface like KCAL for Qualcomm) (thanks to @AndreiLux)
* Interactive governor updated (will stay on min freq and not ramp up when load is <5%)
Older versions changelog:
Version 1.7
* Further LMK updates. Ported LMK driver from arter97's S6 repository (much faster code with less task searching and choosing loops)
* MM updates needed for new LMK
* Added several protected apps within code
Version 1.6
* Reverted some LMK changes and fully implemented ADJ_RBTREE in Samsung's OOM LMK code (this should fix some performace issues (like small lags) while freeing RAM)
* Added several system processes in LMK protected apps (LMK won't kill them unless your system RAM is highly overloaded and on verge of collapse)
Version 1.5
* Interactive governor optimizations and tunings from other Exynos kernels and other devs + me (mostly from S6 kernels)
* Interactive governor screen off power save
* MM updates
* MemInfo updated so Android OS can have better memory stats and thus better memory management

CPU OC is unnecessary for our device.
And CPU underclock won't save more battery.
It'll actually drain more battery.
On very low freqs CPU can't finish task and needs to bump freq up. The freq changing is much more power costly than being on stock 500mhz min for A7 and 800mhz min for A15.
Look at power curves.
We have power curves similar to those on 5433, just about 20% lower I think
This are high performance cores (A15, A57, A72...)

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And this are for power-saving cores (A7, A53...)
The shape of curve for our chip is almost same, only with lower consumption. Look how exponentially it increases as you put frequency after 1.2GHz.
So if I enable OC to, let's say, 2GHz, then power consumption would be 20% higher than on 1.9GHz and performance would be 4% higher.
But don't let that fool you. Phone may last 2s-3s on 2GHz. Then it would throttle down when it overheats due too much power dissipation.
So in the end you get much lower performance than you would have on 1.9GHz.
And keep in mind that Exynos 7420 is built on 14nm FinFET technology, and Exynos 5422 is 28nm HKMG.
So we may use a bit more power than 7420.
My observation:
I get maximum performance on 1.8GHz. Phone is heating at least 10 celsius degrees less than on 1.9GHz so almost no thermal throttling.
For games and high performance apps, I suggest that you lock A15 core cluster on 1.8GHz.

Tips & Tricks
I suggest you use Xposed for Samsung MM ROMs and Xposed module called XTouchWiz.
They are both maintained by @wanam
XTouchWiz Recommended settings:
* Disable TouchWiz DVFS (you'll get enormous performance boost)
* Disable KNOX/TIMA (disabled TIMA in kernel, but XTouchWiz uses Xposed method hooks to disable it in ROM)

Not on boot. You can set it to permissive in Synapse.
But I use patched sepolicy from SuperSU (thanks to Chainfire), so permissive/enforcing shouldn't make too much difference (or problems) anyway

what about battery life

For me, alpha versions were awesome. This one should be better.
Especially when on WiFi/Data or any other internet connection.
If you have bigger battery drain, then you have something wrong in you ROM setup/boot scripts.
Plus wait for a few days to get accurate battery life. I released this version today so no objective batt life readings yet
Be patient and ot'll pay off

Does it support private mode and other *stock* kernel supported apps?

Try and see. I have no need for private mode and I don't use it.
Fingerprint works, S Health and other work too.
I suggest using XTouchWiz and disabling DVFS

I am tested ut and not that much i will use it for 24 hours then if i saw any bug i will report dude i lived ur LP kernel and this one not bad for battery but greenapple kernel was better hope see next version with better battery
Top notch kernel as always.. can u share ur best battery setting in synapse mr @duki994 because i need a little more battery saving..
Thanks :victory:
Report after first day 0f usage ) kernel is amazing ) battery life is wonderful ) my phone isn't lagging at all)) good job @duki994 ) also thanks to @somadsul for his green apple Kernel ) keep it up too or duki will understand that he beyond compression and will add features not one by one but half by half as nvidia do now )))))
P.S that was a joke
P.P.S about kernel awesomeness it's not a joke
Cheers ))

If you really need mre battery saving then replace battery. I'm serious.
I get like 1hr SoT and 80% battery. Just a bit worse than my old G2 with enormous masterpiece, Dorimanx kernel.
Use XTouchWiz and disable DVFS. Everything else sjould work much better.
I can't fully disable DVFS for exynos 5422 in kernel. It's at least 70% userspace and uses ioctl commands.
That's what Samsung did. Disable DVFS via XTouchWiz (via Xposed framework) and you're OK
Can't fix that in kernel. And it uses too much battery.
For power saving, undervolt by 25mV all cores (A7 + A15) and use ROW or NOOP sched. But performance will be at leas 10% lower for maybe 30min more SoT. Maybe !!!

Would you recommend using the PE workqueues and HMP little packing options with your kernel?
@duki994 Dude im waiting for this.. Great work.. Could u please add insecure ADB and enable ADB debugging default so as to easy to take logs while in bootloop as i was always playing with system files.

Info & Thanks
What you need to know before you use this kernel.
This kernel got Selinux Permissive state as it supports more apps like TiTaniumbackup.
Reverting back to a Selinux enforced Kernel (stock) is no longer a problem from Rev3.0 and up.
You can set Selinux Status with the included Synapse app
You want to know why this kernel comes with Selinux included, google for Selinux and search your answers.
AllCast mirror will not work as this is a Samsung thing and not opensource.
If this is a problem for you, don't use this kernel.
DISCONTINUED , A NEW THREAD WILL BE OPENED FOR THE NEW KERNEL SUPPORTING ONLY THE KITKAT BOOTLOADER.
NO JELLYBEAN BOOLTOADER SUPPORT, IT IS TIME TO MOVE FORWARD.
INSTALLATION
Take a full nandroid backup.
NO NEED TO BE ON ANY KITKAT BOOTLOADER (your wifi will work with this kernel)
YOU NEED TO BE ON A KITKAT TOUCHWIZ ROM.
Install with cwm
Thanks:
sidmoraes for pointing me to other kernel source that I could use as base, still had to change some stuff but this is better then waiting for samsung to release there source, if they ever will. (Finally Samsung released source)
Andreilux - Faux123 - Yank555.lu for kernel work

Never install a kernel that is not for your device, it will cause a hard brick.
Stock kernels can be found in the SphereKat folder of your device
The only good app to control this Kernel is the included SYNAPSE appExample of what synapse looks like,THIS IS JUST A EXAMPLE.
SphereEngine KERNEL Features
If you change nothing these are the following Features/optimisations you get compared to Stock:
SELINUX protection included but set at Permissive = No problems wit apps like Paragon and Titainium.

S-pen alignment is fixed in the kernel and rom so you need both to have 100% accuracy.
This kernel will fix it for 95%. The other 5% is in the roms framework.

Note to all users:
Don't be a lurker, hit thanks as it took plenty of hours to build this.
Samsung didn't release the kernel source (not yet) so a lot of debugging was needed to fix problems like the sensors not reporting correctly.
This is the only thing I ask, hit thanks if this helps you.
It is free and enjoy it.

About the lurkers,
Martin from this post isn't one as he is a donator and thanks hitter.

[*]GPU step 5 included, now max it will go to 533MHz
[*]Auobrightness sensor fixes part2
[*]CPU sloop adjusted
zzmoove profile nr8.
GPU control is not possible , maybe later as the GPU driver is totally different then on JB.

Flashed and while it seems to be working fine for the most part, my CPU is constantly maxed out for some reason. I changed no settings or anything, and it was idling fine before flashing. I'm sure it might be something with my device, but I thought I'd put it out there just in case it's not. I'm going to mess around with some settings, see what I can do, and see if it changes.

Like you said, it could be something with your device, mine goes into deep sleep and it has gone as high as 90% deep sleep. Pretty amazing I would say and great job by @civato. Are you on pegasusq governor?

I was indeed using pegasusq. After trying multiple different governors and nothing changing (even stayed at 1600mhz on powersaving), I've decided to wipe my device entirely and start from scratch. No biggie. If I narrow it down to a specific app or device setting that was causing it, I'll post it so people are aware.
09/Jun/2014 First Public release Rev2.2
[*]Memory Leak fix cpu stats
[*]Memory Leak fix Kernel Ext4 & Power
zzmoove profile nr6.
I recommend not to use Powersave governor as is very buggy. Next release will it have removed as it useless.
Best governors are Pegasusq - Adaptive and zzmoove.
I am running it an am happy to report no issues. The only changes I made were to up my top cpu speed to 1.8gzh. All govs are at default. Thanks again. Can't wait to see what is next in the works for this tablet.

duki994 Kernel for Stock TouchWiz LP ROMs
A personal project that had good results and I wanted to share it with others
It's based on official Samsung sources for Lollipop firmware.
Important note:
This kernel should work on any custom ROM that is stock lollipop based
Features:
* Wolfson Audio control (thanks to @AndreiLux)
* Battery charging control (thanks to @AndreiLux)
* CPU voltage control for both A7 and A15 cluster (thanks to @AndreiLux)
* Exposed all OPP voltage controls (thanks to @AndreiLux)
* Powersuspend v1.7 by @faux123 and @Yank555
* LMK, MM and FS powersuspend mods ported from @dorimanx's LG G2 kernel
* SCHED code fixes
* SCHED: HMP thresholds changed and new patches implemented
* Many changes related to ARM instruction code and lowlevel ARM core management
* Enabled NEON mode in kernel with full VFPV4 support
* Added new SHA256 and SHA512 NEON accelerated algortihms - now blazing fast
* UKSM (Ultra Kernel Samepage Merging) - algorithm that's better optimized than standard KSM
* WiFi standby wakelocks (PNO wakelock) reduced
* WiFi userspace power mode/DTIM change (for advanced users ONLY)
* WiFi driver switched from deprecated earlysuspend to use newer powersuspend driver (this is to fix some of bugs that could lead device kernel crash)
* NET updates
* Enabled all TCP congestion protocols and set Westwood as default (best wireless performance)
* Disabled KNOX
* SELinux disabled in kernel
* Fully configurable in Synapse (download from Google Play)
/* Important note to other devs */
You cannot include this to your ROMs. I can't be responsible if anything goes wrong, I can't help with any issues without knowing kernel version and users should be routed to this thread if they want this kernel, or if you recommend it. I think that it's best to separately view custom ROM and custom Kernel, so each dev (ROM or Kernel one) can work on bugs/features and make it as compatible as it can.
However, you can add this thread link and mention me in your thread, so people would know where to ask if some kernel problem arises
Warranty void
By flashing this kernel you will void your warranty. I'm not responsible if you brick your device, or if someone starts nuclear war.
Note:
Don't change voltages on "Busses" tab if you don't know what you are doing. It can reboot your phone if your memory controllers, ISP or MMC controllers can't handle low voltage.
WiFi pasword resetting fix:
Code:
1. open your build.prop file
2. find line ro.securestorage.support
3. change it from true to false (if not already false)
This line being on true will make your WiFi not work good with this kernel. This is due to Samsung's rooting restriction and other Samsung specific workarounds to stop rooting and flashing. Any custom ROM probably has this line changed to false.

How to build this kernel guide
PREREQUISITES
What you need installed to compile
gcc, gpp, cpp, c++, g++, lzma, lzop, ia32-libs flex
If on 64bit Linux, install gcc multilib
Project folder structure
--project_root/ #### can have any name
-----ramdisk_source/ ## defined by RAMDISK_TMP var in script
-----ramdisk_tmp/ ## defined by RAMDISK_DIR var in script
-----kernel_source/ #### can have any name
-----RELEASE/
TOOLCHAIN INFO
Toolchain is already into kernel dir. You just need to have
correct folder structure and run this script. Everything will be auto-built
FLASHABLE ZIP
Flashable zip will be located in project_root/RELEASE directory
and will have name Kernel-slte.zip
All other explanations here:
https://github.com/duki994/SM-G850_Kernel_LP/blob/master/build_kernel.sh
Clone ramdisk source in ramdisk_source
Clone kernel in kernel_source folder
Be sure to have project directory structure as written above
After that, you just need to run:
sudo bash build_kernel.sh
in kernel folder. And voila. After finished you have Kernel-slte.zip in RELEASE directory
If it show any errors, open kernel source and type in terminal:
chmod -R 755 *
Then repeat sudo bash build_kernel.sh
awesome job, thank you
finally undervolt .. yay

edit: volume in the audio also work, louder headphone.
Thanks, I'll try it.

Battery? It's better than stock for me. For screen on, this morning I had 50mins SOT and 87% battery left. That's even better than my LG G2, which is a beast according to tests
My father uses Galaxy Alpha, and yesterday he managed to get 4h SOT with HSDPA data on.
When screen off (in suspended mode) it's very low power consumption due to Powersuspend driver. It's better than stock.

I have no access to G850L model. I don't know if it will work.
During this week, if I have enough time, I'll download G850L source and build it with all mods/features and give you to test it
thanks duki994.
which app I need install to control on the kernel?
hi!
1. how do You undervolt by 20mv, in synapse i have steps like 1x,xxMv and can set up -25Mv??
2. I have strange warning message after installed this kernel. it says phone needs to reboot. after reboot the same. just annoying

1. Our voltage regulator accepts 6.25mV step. So you can UV/OV in multiples of 6.25. When you do math, 6.25mV x 4 = 25mV
You can't UV -20mV. You can UV -18.75m (3 x 6.25mV). Next step is -25mV (4 x 6.25mv).

No UV. All stock. Only changed earpiece volume (incall speaker volume) to higher (+4dB if I recall good from this morning). It's for better hearing incall
UV generally doesn't reduce battery consumption (it's maybe 1%-3% less power usage). Real benefit of UV is lower CPU heat and prolonged life of motherboard.
Some chips can't handle UV at all. Some can be UV by as much as -150mV. It all depends on specific chip that came out of fabric process. Note that UV brings instability on some devices.

imo it's not really "cant reach",
but it optimized so cpu load is still under 1.4ghz.
Performance governor ramp up your CPU at the highest value, it doesn't matter were you are in game or just playing music.

Well I used the Ampere app, the max.amount of current I got was 1010mAh , with constant values revolving around 700-800mAh. Others can also check. I'm using the stock charger.
After install the kernel I can't unlock my phone, I'm using pattern unlock. Everytime that I try to unlock a black screen appears and go back to unlock screen.
I had the same problem with latest version of octopus kenel and I have to use and old version.
Any idea how to fix this problem?

this is the only one that made my 紅米2 react properly on dt2w
(feature i missed the most, and coming back big style) {still waiting for a stable berserk to be honest}
8 stars (out of 5) for the looks/user/aroma approach - specially for people not using kernel managers (i'm not 1 of those, but solidarity is important)
has every other "crowd pleasers" working except for control freaks (just kidding) + screen/color profiles << this is not a plea

/* Important note to other devs */
You cannot include this kernel in your ROMs. I can't be responsible if anything goes wrong, I can't help with any issues without knowing kernel version and users should be routed to this thread if they want this kernel, or if you recommend it. I think that it's best to separately view custom ROM and custom Kernel, so each dev (ROM or Kernel one) can work on bugs/features and make it as compatible as it can.
However, you can add this thread link and mention me in your thread, as so people would know where to ask if kernel problem arises. I would do the same for you
Warranty void
By flashing this kernel you will void your warranty. I'm not responsible if you brick your device, or if someone starts nuclear war.
Note:
Don't change voltages on "Busses" tab if you don't know what you are doing. It can reboot your phone if your memory controllers, ISP or MMC controllers that can't handle low voltage.
If someone happens to have bug with WiFi saved password being lost every reboot, here is fix:
WiFi pasword resetting fix:
Code:
1. open your build.prop file
2. find line ro.securestorage.support
3. change it from true to false (if not already false)
This line being on true CAN make your WiFi forget password each reboot. This is due to Samsung's rooting restriction and other Samsung specific workarounds to stop rooting and flashing. Any custom ROM probably has this line changed to false.
Changelogs:
Version 1.8
*Added LED fading control made by @AndreiLux
Version 1.7
* Fixed interactive governor logic. I forgot logic code for CPUFREQ_RELATION_C. Now interactive is 50% more responsive.
* Backport some ASLR changes
* Added ZEN IO scheduler and set it as default (beware that Synapse will auto reapply YOUR settings after boot, so ZEN won't be set. If you want it set it in Synapse I/O tab)
* updated GPU ION memory allocation code
* Exposed HMP up/down threshold tuning in Synapse ---> "HMP tuning" tab
* Fixed false adaptive LMK triggers --> less RAM clearing when not needed
Version 1.6.1
* GPU control code revamped
* GPU frequency scaling logic revamped. Fixed various bugs introduced in stock and in min/max control code + optimizations
* Synapse: added monitoring current values for DVFS Interactive governor (for GPU).
* DVFS Interactive governor is now working very good.
* Sensorhub wakelocks reduced (sensorhub and ssp wakelocks)
Version 1.6
* Disabled TIMA and some other Exynos specific non needed stuff
* New GPU Governor - Interactive
* GPU governor Interactive tunables exposed in Synapse
* Many GPU control code optimizations
* Reverted to stock DVFS OC table
* Fixed DVFS table for our SoC
* Set SELinux permissive on boot --> But after 20sec some ROM binary sets it back to enforcing.
Who wants SELinux permissive, he can set it in Synapse. But ROM boots permissive
* Better min/max GPU freq guards
* Updated touchscreen with powersuspend driver to see if it's possible to use wakeup gestures.
Version 1.5
* Disabled GPU tracing to squeeze out 3-6FPS more in games. Also should run smoother now.
* Framebuffer cmap buffer overflow check
* GPU OC --> 600MHz and 677MHz steps
---> use very carefully
* GPU min/max clock control
Version 1.4

Known bugs:
* Turning headphone EQ on will lower headphone output volume.
* If you set any of Headphone EQ bands to 3dB, Wolfson audio chip will produce very unpleasant noise and stop playing.
It seems that it's inner HW components don't like that gain.
Every other setting will work, just don't set any band to 3dB Works after audio updates
* Charger controls for AC current are not reacting to change.. New charge control driver is good now.

CPU OC is unnecessary for our device.
And CPU underclock won't save more battery.
It'll actually drain more battery.
On very low freqs CPU can't finish task and needs to bump freq up. The freq changing is much more power costly than being on stock 500mhz min for A7 and 800mhz min for A15.
Look at power curves.
We have power curves similar to those on 5433, just about 20% lower I think
This are high performance cores (A15, A57, A72...)

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And this are for power-saving cores (A7, A53...)
The shape of curve for our chip is almost same, only with lower consumption. Look how exponentially it increases as you put frequency after 1.2GHz.
So if I enable OC to, let's say, 2GHz, then power consumption would be 20% higher than on 1.9GHz and performance would be 4% higher.
But don't let that fool you. Phone may last 2s-3s on 2GHz. Then it would throttle down when it overheats due too much power dissipation.
So in the end you get much lower performance than you would have on 1.9GHz.
And keep in mind that Exynos 7420 is built on 14nm FinFET technology, and Exynos 5422 is 28nm HKMG.
So we may use a bit more power than 7420.
My observation:
I get maximum performance on 1.8GHz. Phone is heating at least 10 celsius degrees less than on 1.9GHz so almost no thermal throttling.
For games and high performance apps, I suggest that you lock A15 core cluster on 1.8GHz.

i got tears in my eye,thank u very much,will test and report asap
kernel still enforcing,hope can permisive next build,hard 2 install audio mod like dolby
hope there will be overclock options and lower min freq.
the gpu voltage @266mhz weirdly high @default in synapse.
cpu workqueu checklist doesnt stick after rebot
kernel dont boot in BPC4 but runnin fine in BPC8 strange because i use the same BL
stuttering in music with screen off
other than that great kernel waiting 4 d next build
Good work.. Thxx
nice work mate... phone is not laggy now..
Bro I guess selinux is still enforcing. can we get a permissive feauture in next update.
i'm install dolby digital pluse with this kernal..but not work why>

I know about PE switch. I mady typo in ramdisk. Will be fixed
I use BOL2 ramdisk and BOG4 (latest kernel sources given by Samsung).
It should also work on BPC4. But use BPC8 if it doesn't.
GPU voltage is bug or made intentionally by ARM/Samsung. I lowered it to 25mv higher than 177mhz voltage and it works.
Also new charging driver made by me will be included in next release for testing

Probably SELinux enforcing.
I will leave it on by default due to Stock ROM apps need, but I'll add checkbox/switch in Synapse to switch it enforcing/permissive. It should fix those problems with dolby sound.
Why install Dolby sound? WM5110 is awesome and as good as my ASUS Xonar Essence One DAC. And I'm audiophile. That's why I bought this phone

I will also disable PE workqueues by default. They drain battery more in heavier usage and make sound stutter.

Type this in terminal:

It will disable PE workqueues. In some workloads I noticed that they drain battery more. I'll fix this in next build today and non-working PE workq. switch

* Fixed critical bugs in ADJ RBTREE code, used by LMK driver
I recommend you to critical update kernel now.
* Disabled adaptive LMK by default and added userspace switch to turn on/off adaptive LMK in Synapse (in Misc tab)
* Tuned LMK minfree values.
* Updated BINDER and FS critical code

@jawzf
Yeah. That would be cool. I have exams next week, so I don't know if I can merge those changes for sweep/tap functions until then, but I want those features too. I come from G2.
Double tap is natural to me. Maybe only sweep functions can be implemented. I know LG's double tap drivers. It's coupled with custom synaptics touch chip firmware which has HW level support for double tap,
Note that sweep/double tap funcs may drain much more battery. And our driver is different from G900F.
But I'll merge and adapt 'em when time allows
EDIT: Charge current control driver is working as it should
Well looks like is time to test your kernel

sys.config.spcm
Remove all of them, and then add these lines:
Code:
ro.config.dha_cached_max=16

ro.config.dha_empty_max=32
ro.config.dha_empty_min=8
ro.config.dha_empty_init=32
Enabling zRAM
Find these lines:
Code:
#ro.config.zram.support=true
#ro.board_ram_size=mid
Remove all the hash on top of the lines, then save build.prop, restart your phone. Done!

Yes I also notice the graphics lags of the kernel, probably is from Mali driver. Stock also does that too. I'll try to add frequency controller if I can
And for OC, maybe it isn't needed, since it just kill your battery worse. Mostly the CPU will run at 1,2GHz instead of maximum 1,3GHz (well for some situations like gaming, it runs on maximum freq)
