Off-topic: Fixing multitasking for crappy TouchWiz and enable zRAM
Multitasking:
First, open your build.prop, find the lines starting with:
Code:
sys.config.samp
or
Code:
sys.config.spcm
Remove all of them, and then add these lines:
Code:
ro.config.dha_cached_max=16
ro.config.dha_cached_min=8
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!
Seems like this phone isn't too famous like original GP yeah :silly:

@doesntexits Thanks for all your work. I appreciate all your hard work, tho I don't have this variant but one of my friends does have it so I'll try it on that device nd will let you know.
Nd yeah don't worry about the crowd, you'll have it soon.
One more thing, the tweaks in 3rd post, Mostly probably they work on G530H?

Just try it. I think that should work
But anyway, use CM instead. Stock Sammy is crap you know
This kernel is very good, but please make overlock, and performance of graphics,i have some times lag, please brother, overclock and graphics performance please!
Working :highfive:
Thumbs up for you

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)

Please , brother to increase graphics performance and the overclocking CPU is fine, but please increase graphics performance or make overclocking the GPU and this is perfect please thanks brother, you are the best,great job
I think I'll ask mods to move all of the G530H threads to original development section, because in a few hours, this thread will be burried down, and no one will see it until they choose to open the whole development section
have any news of CyanogenMod for this model?
Kernel Is Good but not stable
Excellent implementations of battery saving tweaks :laugh:
Lost only 3% during 8 hours on standby at night , :good:
However It compromises between performance for more battery . . .
There's lags more than stock

Well, it seems its about time I release one of the most awaited thing (after a long long time) for this device.
Presenting you with a piece of real dev (kinda), Zapdos Kernel.
Features
Compiled from source.
Compiled using ARM official toolchain (4.4.3).
Bootable on ALL firmwares. This removes the distinction between 'old' and 'new' firmwares.
Swap Support. You got that right, swap support on your favorite ROM, regardless of it being 'old' or 'new'.
CPU Frequency Scaling. Apps like CPU-Z and others will now show more details than ever.
1400 Mhz Overclock.
Governors enabled.
More Governors added.
CPU Idle Power Management Support.
More CPU Frequencies.
Modified Voltage table for better battery life. [UPDATE]
Settings -> Battery, will now show battery usage by apps too. Partially fixed in v2.0 Update.
More I/O Schedulers.
Dynamic Read Ahead Support.
Dynamic Fsync v2.0. Gives massive boost in I/O Performance, and is reflected in benchmark. (Thanks to Faux123)[UPDATE]
Added Double Tap 2 wake feature.
Added bunch of TCP Congestion Controls.
Added Mali GPU profiling.
Based on gzip compression method.
Insecured boot.
Easy root enabled.
Bunch of corrections.
Uses Custom boot splash.
Added VR I/O Scheduler. [NEW]
Added Zen I/O Scheduler. [NEW]
Added TripnDroid I/O Scheduler. [NEW]
Added FIFO I/O Scheduler.[NEW]
In-app updates. [NEW]
Disabled Gentle Fair Sleepers. [NEW]
Asynchronous I/O latency to a solid-state disk greatly increased.. [NEW]
NOATIME and NODIRATIME by default. [NEW]
Disabled CRC check. [NEW]
Optimized SLUB. [NEW]
Optimized Square root algorithm. [NEW]
No dirty things in kernel version. [NEW]
Bugs/Glitches
It is highly likely to experience bugs and glitches, because CPU frequency is enabled. Samsung had disabled it for stability issues.
After reboot, battery remaining value drops drastically, but will increase back eventually to normal, its a glitch, not a bug.
Attaining CPU frequency scaling like other Android Phones is difficult, real-time CPU Frequency scaling isn't possible because, if tried, results in crash.
Broken battery usage by all apps after overclock. Partially fixed in v2.0.
DoubleTap2wake is experimental, it sometimes does not work by name (i.e you need to tap more than 2 times, but it will work for sure).

Frequently Asked Questions
Q. I tried/want to try this, but I have some doubts....
A. You are reading the right post, find your queries below, if not post it.
Q. Nice work dude, thanks....
A. Well, XDA has done a great job in reducing a man's effort of typing 6 letters to just a click on a button called 'Thanks Button'. Didn't they?
Q. Can I use it in my ROM/MOD ?
A. Sadly, NO, sorry. Since the sources have been provided, also kernel may cause problems when flashed after ROM, so its is not recommended to include it in a ROM. But you can obviously refer others to this kernel.
Q. Will this work on GT-S5280?
A. Well, since I don't have that variant, and since its a kernel, I would say not to try this on GT-S5280. And hence, No.
Q. What version of CWM do I need to use?
A. 6.0.2.8 or 6.0.3.7 only, no CWM v5.
Q. I tried this kernel out of excitement, but now realized that it was not for my phone.........?
A. May God Bless You.
Q. What are the features/speciality of the kernel?
A. First, read the 1st post. Second, get/change your spectacles.
Q. Will this work on XYZ Firmware/ROM for GT-S5282?
A. Hell Yeah!!
More Q/A will be added eventually.

Reserved for kernel tweaks and settings
To get the most out of this kernel, install ThunderZap Control App by @varun.chitre15
FREE Version - https://play.google.com/store/apps/details?id=com.varun.thunderzapcontrol
PAID Version - https://play.google.com/store/apps/details?id=com.varun.thunderzapcontrolpro
**Note - DO NOT try to mirror this app. If you want to download use Google Play Store only. If you want to share, share the links given above. DO NOT upload the app to any 3rd party hosting site. You have been warned.
In this app, various sections can be accessed by swiping from left edge to right.
CPU Section
Governors - Use smartassV2. You can use ondemand to get the core running at 1400Mhz.
You can adjust max and min frequencies too. Always keep max frequency 1000 Mhz or above.
Memory Management Section
I/O Schedulers - Use any, unless more are added.
Always keep the Dynamic Fsync option on (layout issue there, but blue means on).
You can play with other options too, instructions are mentioned there.
Network
Use any control, I would recommend Westwood. (Layout issue there again).
Don't forget to enable set on boot, can be found in settings.
DoubleTap2Wake
An update to this app should bring double tap to wake toggle under Special Section (And that is why I highly recommend to use this app). But for now -
Install Terminal Emulator - https://play.google.com/store/apps/details?id=jackpal.androidterm
Run the app, and then type -
Code:
su
echo 1 > sys/android_touch/doubletap2wake
It can be done using adb shell too.
Run Antutu benchmark, and feel the difference.
Will be updated as per kernel.

Nope, I compiled it using ARM toolchain as they had asked to. But I plan to switch to Linaro Toolchain.
And I am not sure whether it will boot CM 10.1 (chances are there though). But it boots perfectly on all stock ROMs.

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.
Changelogs:
Version 1.4 BETA

* Added misc tab:
+ ability to take logcat,dmesg,last_kmsg
+ HMP Little packing switch ON/OFF and explanation
* Added optimized ARM RWSEM algorithm
* Fixed HMP so HMP little packing would work good with our implementation
* thermal IPA(Intelligent Power Aware) now updates power tables immediately when voltage changed from Synapse
* entropy depletion fixes
* Enabled FRANDOM random number generator module for more entropy and less lag
* Added NEON instruction accelerated SHA256/SHA224 algorithm. Now we have SHA384/SHA512, SHA256/SHA224 and SHA1 algorithms NEON accelerated - blazing fast
* HMP little packing switch for Synapse
Experimental option made by nvidia. It groups tasks so more of them would be scheduled across power saving cores (A7 cores in our CPU). It may or may not save battery depending on your usage.

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

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.

On which ROM are you? Everything works for me on stock. I have to see if anything changes it.
Did you set secure storage to false in build prop?
I'l automate that in next build.
Kernel doesn't mess with options like recent buttons and Java written parts of Android OS.

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.
Google Play link for lazy people:

/* 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.

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

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_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"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

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

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

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 !!!

Welcome to hadesKernel
Some personal thoughts:
- this kernel works only on J5 2015 versions. I`m not responsable for what can happen if you flash on other devices.
- v2.3 for J5 already includes all the previous things from A5 releases.
- if you take any of my work without my permission i'll report you, and you'll probably get banned.
- you should read at least install instructions stated in this post - i won`t offer support for any issues regarding installation;
- bug reports without device variant and logs can't be considered bugs - make sure you provide detailed info when reporting bugs;
- press 'Thanks' button instead of saying it - it will keep the thread clean and keep me motivated to do more;
- feel free to donate to me if you want to support my work.

FAQ:
Q: My wifi is broken after flash. What to do?
A: Flash latest modem available for your device.
Q: Can`t connect to wifi network. What to do?
A: Reboot the phone, reboot the wifi router/ap, make sure you don`t have mac filtering enabled on ap/router.
Q: MAC adress has changed. What to do?
A: There is nothing you can do. That happens because of newer wifi module, built along with kernel, from the latest sources. If you can`t connect see Q2 above. I won`t change back to legacy wifi modules, at least not now.
Q: Device appears as "unauthorized" in adb and notification to authorize doesn`t appear. What to do?
A: Enter developer options, disable usb debugging, wait 30 seconds and re-enable it. Now you should see the notification to allow debugging.
Q: loading
A: loading

I'm using this kernel on my Stock 6.0.1 rom & I must say that this is one of the best kernels for J5.. Its very fast & stable..
Thank You So Much..

Great .
Fast Kernel, Stable. (First really good kernel for J5)
From the tester to this build your kernel has worked perfectly. (Commenting here your tester)
My new rom with your kernel is amazing.
Cheers! :highfive:

Hi @By Zonik ..
Waiting for your rom (v2) bro..
Some q's
Fast charge as in fast charge?? Does our present kernels support that, beacause it's pretty slow.
Any plans to follow it up for a non touchwiz based rom??
does it support skies rom beta ??

Does the kernel work well with a single processor at the frequency of 50Mhz?
If you set a different GPU frequency to 720Mhz when the GPU is at 100%, is the Max frequency set or rising to 720 ignoring the set frequency? ?
Finally something interesting for the lands of the J5
For me the link doesnt work i just get this:

I will quote my friend @Bulgaricus for this
...we force supporting devices such as laptops and desktops that have fast charge to provide the quick charger to our phone.
I will see what can be done in the future for non touchwiz.

From what i know Skies Rom is based on touchwiz so it will work. Test and report.

I added 50Mhz for some certain scenarios, to step down the freq if the load is small - screen on but idle (i have screen timeout set to 10mins), or screen off and awake (for AOD on the roms that have it-my rom for A5). Anyway i have custom script in ramdisk that bypasses stock init.qcom.post_boot.sh and sets custom loads for all the frequencies, so the device can go down even to 50Mhz, but step up if the load is reached, so it doesn't lag at all.
About gpu - from what i saw it sticks to maximum set (i use kernel adiutor).
I mostly cherry-picked features and fixes, even from your j5(6) kernel [emoji16] since all are based on same soc. This project started as personal kernel, permissive with otg enabled (because A series has OTG disabled by Samsung), and after that decided to add more things and make it public.
Cheers!

You can see the GPU frequency in real time by using these commands in Terminal (PC):
Code:
adb shell
cd /sys/devices/soc.0/1c00000.qcom,kgsl-3d0/devfreq/1c00000.qcom,kgsl-3d0
while true; do cat trans_stat; busybox sleep 0.1; done
1) The path may be different.
2) The current GPU frequency is the one with the asterisk.
3) Total transictions means the total switches between GPU frequencies.
Try these commands to confirm that the GPU frequency is stuck at 720.
We can bring the current fast charging also on custom roms or even improve the fast charging to support custom mAh and stuff like that. But forcing a battery to charge faster than it's limit can demage and reduce the battery life drastically so I think we will leave it just like that. Greetings

Skies Rom beta is a Note 7 Port rom .. so it is Grace UX not touchwiz ..

I know, that you have cherry pick from me?
I also found something interesting in your code
Referring to the intelli thermal, I do not know why faux124 used a different thermal control for the TSEN8974. I found that version 1 gives some errors in the logcat when I boot up the phone
I also started my kernel for personal use, specifically to be able to use viper4 ? I just needed the kernel to be permissive. And now look where the kernel go

Grace UX is touchwiz based. Non tw roms are lineage, cyanogenmod, or any other that uses AOSP as base.

I removed it from features/changelog since isn`t activated yet. I saw too late in msm8916 defconfig the CONFIG_THERMAL_MONITOR=y so the intelli_thermal isn`t there yet. I can`t even finish the build (lots of errors), and you have errors in logcat ?. You are way far than me. For now i didn`t had time to chase those errors. I`ll look more maybe next week. Anything else interesting in my source? ?
Cheers!
PLEASE READ THE FULL POST BEFORE FLASHING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I present to you a kernel that I have been working on to give us J7 owners a better experience, which I have named Afterburner.
Before I begin, this will void your warranty, as with any other ROMs/kernels/etc. I will NOT be held responsible for anything that goes wrong from flashing this kernel such as your phone breaking or catching fire/ etc etc.
Anyways, this is ONLY FOR J7 2015 devices and TouchWiz based Nougat roms!!!!!!!!
Installation
Download to your sdcard or external sd card then reboot to recovery.
Go to "Install" in TWRP and then browse to the location you downloaded it to. Once there, click on the zip file you downloaded and swipe to flash. You will be greeted with a screen that tells you the kernel version and date, touch Next. Now you will come to the install options. Select the options you wish to install (Permissive, init.d, and busybox). ALSO, IF YOU HAVE A J700H MODEL PHONE (3G version) THEN SELECT THE J700H OPTION, OTHERWISE YOU WILL HAVE BUGS!! Now, select next and you will come to the root options screen. Select whether to install supersu, magisk, or no root. Select Install, then set back and wait. Once it's done select next. Finally, if you want to return to TWRP(Recovery) then uncheck the reboot option and touch Finish, otherwise just touch Finish to reboot. Your device will bootloop once (with supersu) or so then will boot. The first boot after installation will take a while. Enjoy!!!!!
If the kernel won't boot then go into recovery and wipe dalvik and cache then reboot and wait... It will boot, I promise
I will be updating as I add features.
Downloads are in second post!!
Changelog
v17.11.03.4
-Added a LOT of I/O schedulers
-Removed a few governors because they caused random reboots
-Rewrote the CPU hotplug to use CPU load instead of frequency for better accuracy when to turn CPUs on or off. It is now a little closer to stock, but when turning off cores it will turn off the least busy CPU first (So, yes when your kernel app tells you that CPU0,1, and 7 are on and the rest are off it's not a bug!!)
-Fixed some powersuspend bugs
-This update should dramatically improve performance, especially in games
v17.10.15.11
-Added LZ4 compression and enabled in pstore and ZRAM (Makes memory management a little faster)
-Added power suspend driver (finally) and make all included governors use it
-Created a universal way for governors to calculate CPU load and incorporated into all governors
-Added deadline I/O scheduler
-Added Intelliactive and Pegasusq governors and removed Hyper governor, as it lagged pretty bad
-Intelliactive and Interactive governors as well as the CPU hotplug driver now take GPU load into consideration when speeding up or slowing down (or hotplugging in/out CPUs)
-Hotplug driver also takes CPU load into consideration using the same load calculations as the governors
-GPU settings have been adjusted to save a little battery
-Westwood now the default TCP congestion algorithm (Should speed up internet a little)
-Many bug fixes (behind the scenes) as well as optimizations
v17.9.30
-GPU overclocked to 800mhz from 668mhz!!!! Enjoy smoother performance in games and touchWiz
-wq_power_efficient enabled by default, saves on battery
-Many, many, configuration changes in the kernel to optimize performance and battery life
v17.9.17
-Fixed the governor driver and added zzmoove, hyper, and performance governors. (zzmoove is great for battery. That governor combined with the changes I made in the CPU hotplug gave me 5 hours of screen-on time with 56% remaining on Hyperion v1!!!!!!!!!!)
-Fixed the custom CPU hotplug, during screen off the CPU is only supposed to run 2 cores, before it was running 7 because of a mistake I made in the code, now it works properly and the battery improvement reflects this.
-Changed the way the custom CPU hotplug decides to turn on or off cores, as well as fixed a bug from samsung regarding the same code.
v17.9.10
-Changed version number system to the build date
-Fixed private mode
-Fixed battery indicator while charging with phone off
-Updated Linux version to 3.10.107
-Changed the way my Afterburner hotplug works. Now while the CPU is under load it will turn on 2 CPUs at a time and when the load settles it will turn off 1 at a time, which seems to give a bit of a performance boost
-Updated Magisk to v14
-I'm sure there's more I forgot...
v1.0.0
-Option to install either supersu or magisk root or have no root at all
-CPU Overclocked to 1.7GHz (Improves performance) and underclocked to 300MHz (Improves battery)
-GPU underclocked to 160MHz (Improves battery)
-CPU undervolted (Improves battery)
-Custom cpu core hotplugging allows down to 2 cores running (as opposed to 4 stock), with the ability to hotplug 2 cores at a time (compared to 4 stock) (Improves battery)
-Kernel configuration highly customized to remove knox, tima, and logging that isn't used by 99% of people (Improves performance and battery)
-Custom ramdisk with bloat removed (such as knox and files meant for emulators)

Finally afterburner to nougat, thank you for your hard work bro
already flashed, do you know how i can use cpu no frills?
it doesn't work in this phone, i don't know why
Great job bro already flashed it on Hyperion v2 but you forgot to support private mode i dont mind that but some people will does i think
Great to see you still contributing a lot with providing your awesome work.
Nice work @daishi4u !!
Gr8 work bro
Love ur work??
Nice work, thanks!
Awesome work Bro, no random reboots this time, happy enough, thanks for your all of your hard work
Thanks...but not support private mode

If private mode requires Knox then I removed Knox from the kernel

When are you going to add governors to the kernel?
I think there is a bug. There is no charging sceeen when phone is turning off. I'm using hyperion.
Can someone double check if it's just me with this bug?
My phone cut off and went into a bootloop. To only realize that my battery was dead, but while it was off and connected to the charger, the percentage was staying at 1% and not increasing. I had to reflash hyperion v2 to get back it's kernel and then it started charging. Please fix cuz I did feel a difference with this kernel

I wonder if the phone charges when it's turning off. There're circumstance your batery totally running out. If it doesn't charge when turning off, I think our phones are dead.
Hi @daishi4u - I have random spike of cpu temperature, up to 55 degrees!
They last like 40s, the all goes back to normal for the next half hour.
Maybe the 1.7ghz is a bit much ?
Am using Revolution OS nougat rom.
I think hyperion rom contains same kernel. Is it the same or do I need to re-flash this new one.
????
Good to hear that we still have Afterburner support
Thanks for your work and time...
