[KERNEL][3.4.107][AOSP/CM][GCC5.0]Spirit.Kernel r13[21/4/2015]

Spirit Kernel
This kernel is ONLY for AOSP based ROMs. This will NOT work on the stock Moto roms.
I will update this regularly as I have time and will add new features and fixes as well.
If you have any feature requests or ideas that haven't been seen before, don't hesitate to post it here!!​
PLEASE READ
How to report a bug?
Include the following in your bug report:
The ROM you are currently using + a link to the ROM's thread
A log, preferably dmesgs or kmsgs (use Google to find out how to pull these from your device)
The version of SpiritKernel you use (=rx, e.g.r3)
Bug reports not meeting these requirements will be ignored.
NO BUG REPORTS ON EXPERIMENTAL BUILDS!​

F.A.Q. - Read this before complaining!
1. My phone exploded, HALP!
A: I don't answer to problems without a log. The log file is in /proc/last_kmsg. Paste it on pastie.org and link it on your post. Logcats are useless for Kernel purposes, don't bother posting them.
2. This kernel works on Y or X rom?
A: Doesn't work with ROMs having different ramdisk or any derivates due to their irresponsibility of using a different ramdisk which needs patches that break stock rom users. Use a different rom and don't bother me.
3. OMG BETTARY SUCKZ, IT DEAD IN 45 MINUTAS, HALP!
A: As you can imagine I don't build kernels to decrease battery life. All the battery life problems come from your apps, either Facebook, or Maps, or some Location Service being enabled etc etc. Check your damn wakelocks and fix them, the kernel is not responsible for them.
4. How do I flash this?
A: Reading the OP, theres a reason why I added instructions on it.
5. What is a data loss? Did I just had one?
A: Data loss is simply having the connection cut for X periods of time, usually few seconds. Grey bars means the device is not connected to Google services for some weird reason, but you'll still have internet connection.
6. OP is arrogant, I'm gonna call the Internet Police?
A: Deal with it.

Now our cm12 uses this kernel and if you flash this one you will broke media ( cannot play/record videos )

Yeah... Thankssss

Oh,I'll rebase it in the next build then.
Thanks for pointing it.

Guys is media [video recording and playing] broken?
As said by luca.Just wanted to confirm if I need to change the base.
Maybe can anyone check on latest CM12 build.

YEa I'm sure
When I tested lp kernel on kk media was broken
And new lp kernel is a way better

Eager to use it on latest Builds and requesting to add kexec support if possible

For me, sometimes it works, but then other times won't.

In blisspop video works for a day...then well i moved to stock 4.4.4 for some testing and optimisation on it btw i'm on xt1068

Hello Guys,
After working off to a new base fixed everything in the new build.
Get it https://s.basketbuild.com/devs/DC07/Spirit/titan

Normal moto g or second generation?
And there isnt even franco kernel for this device lol so ofc you screw up.
If you indeed own a moto g 2nd gen (titan) and your are running latest cm12 nightly it is safe to flash this kernel.

Second gen

What
Sent from my Moto G 2014 using XDA Free mobile app

I did not think the new governors nor Min Freq: 96000

Is there anyway to disable the cpu being clocked at 19000 whenever I touch the screen? It's a feature of CM12, however is there anyway to disable this? I tried putting off mpDecision through Faux123 but it still goes to 19000 even with intelliplug and the user defined option. Any help appreciated!
Thanks,

How the hell you have a Moto G 2nd Gen and flashed Franco Kernel? Franco Kernel is for 1st Gen. lol man you need new eyes, even glasses don't help in this case.

any news ? alpha or beta testing? I'am on K920 China with s226 ROW rom unlocked bootloader and TWRP
Thanks for your reply

Try it No promises though

I bought a ROW version with Kitkat.
Updated it for Stock Lollipop.
Rooted it with 0_install_root_K920Pro.bat.
Unlocked bootloader with VibeZ2Pro_ROW_UnLock_BootLoader_L using Qfil
Run (did not flash) TWRP 0_run_twrp_recovery_K920Pro.bat
Backed up my working stock ROM
Flashed DragonVibe8 with TWRP run
Installed XposedInstaller_3.0_alpha4.apk
Flashed xposed-v71-sdk21-arm.zip using TWRP run
Installed GravityBox_Lollipop_5.1.4.apk
Everything on Gravity Box works perfectly on Vibe UI.
Installed Titanium backup, froze unwanted apps.
After I was sure, removed all bloatware which were frozen using Titanium backup.
Installed Device control. Modified CPU and GPU settings.
My K920 is now amazing on performance, power backup, functionalities and features in addition to its lovely Hardware (screen, camera and looks).
Thank you

Hi @Electry, is there a way to make this kernel compatible with cm12.1?
thanks

Hi,
Which options in device control are the best to set?
Not for gaming, just for regular use, surfing , better battery life.
Thanx

Hi, update please
Hi Electry, I would like to test you kernel, now I am only rooted and running the latest (S271) stock ROW. If it is safe to install you kernel over build k920_S271_150907_ROW? If yes, I will unlock the bootloader and install the twrp recovery to test it out. Thank you

Wont this work on CM12.1 ROM?

is there a FIX
or a mode to improve Colors
they are very washed out

Yes.

Hey guys, I'm on latest stock ROM. If I will do a root and flash of custom recovery, and afterwards I flash this kernel, how will I be able to flash OTAs, that'll Lenovo release, if any? Thanks.

Will be working on CM13 on CN version of k920?

And what?
Is.this working on CN phones?

Magiskhide can be made to work?
Is there an LED indicator?

Help & FAQ
THREAD RULES & PROTOCOLS FOR THIS DEVELOPMENT THREAD:
I might not have your device variant and or able to reproduce your "issue". With this in mind, without providing as much information as possible, and resetting your device to a stable unmodified baseline, any potential troubleshooting or logs could be meaningless. So please follow the guidelines set out below. Thanks
BY POSTING YOUR ISSUES IN THIS THREAD, YOU ARE AGREE TO HELP YOURSELF FIRST BY PROVIDING INFO REGARDING:
Code:
1. DEVICE MODEL ?
2. ROM and firmware version (build number, boot-loader etc) ?
3. EXACT steps taken to reproduce YOUR issue
4. Screen-shots (if applicable)
5. Did you read Posts #1-3 completely?
6. Did you search the thread, XDA or GOOGLE?
7. Did you follow the install instructions EXACTLY?
8. What was your previous kernel?
9. Do you have any other known kernel tweaking apps, scripts or mods? ([B]remove them[/B]). [COLOR="Red"]This includes Xposed etc[/COLOR]
10. Try older kernel (if available)
11. Factory reset ?
12. Try latest stock [B]UNMODIFIED[/B] firmware (without custom ROM - if you have installed) and factory reset
13. Delete your ROM BusyBox (kernel uses it's own in /sbin)
ONLY IF YOU HAVE TRIED SUGGESTIONS ABOVE:
Turn on logging in Synapse and save logs AT TIME OF ERROR. AND post together with ALL the above information.
ELSE, DON'T WASTE MY TIME, YOU WILL BE IGNORED AND/OR POST REPORTED !!
THANK YOU :good:
NO FAST CHARGE
If using the pathetic original cable, try disconnect and reconnect the USB cable whilst power is still turned on to the charger
Use a thicker / better cable, will work every time (ie. Note4 OEM cable)
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
I will not build for any device that I can not compile using SAME source, personally test method or debug. Some device variants can compile with same source.
Sorry. I don't have the spare time for any more variant support.
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue
Three choices:
Device > settings > applications > Synapse > force close & wipe data and REBOOT
OR
Remove your ROM busybox from /system xbin and /system/bin (Synapse will use the kernel busybox in /sbin).
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
OR
Try install a different busybox
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
Synapse or BACKUP/RESTORE ISSUES
It's a ROM busybox or sqlite3 compatibility issue
Remove both your ROM busybox & sqlite3 from /system xbin and /system/bin (Synapse will use it's own from kernel /sbin).
Device > settings > applications > Synapse > force close & wipe data
Reboot or re-flash kernel as per Installation Instructions
BACKUP & RESTORE
DO NOT restore profiles from different kernel version
Refer to THIS post for "how-to" screen-shots
Refer to THIS post for a "how-to" video (thanks @aldoblaga )
LOADABLE MODULES AREN'T WORKING
Check your /system/lib/modules directory. Are any ____.ko present?
Did you flash a ROM or wipe the system partition at any point? Doing this will remove them !
Re-flash the kernel will install the modules.
If modules aren't installed after flash, then re-flash and manually mount system in recovery first.
You can check running modules in terminal with:
Code:
lsmod
KTOONSERVATIVE GOVERNOR
Some info from the author: http://forum.xda-developers.com/showpost.php?p=60223338&postcount=3
DT2W & COLOUR CONTROL
No, I cannot make it work properly with single source for all supported variants
CPU POWER CONSUMPTION
The Samsung Exynos 7420 Deep Dive - Inside A Modern 14nm SoC (by ANANDTECH - Andrei)
F2FS SUPPORT
It's not needed. You wouldn't see any difference or measure much, if anything. Not worth the potential trade-off. This is not eMMC anymore
http://bgr.com/2015/03/17/galaxy-s6-storage-benchmarks/
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.
CM SUPPORT
Read Post #12
"Unauthorized actions have been detected, reboot to undo changes"
As it's a common warning found with all KNOX enabled android devices, you would have found the answer by Google search and also that it is actually unrelated to kernel and also unrelated to this kernel development..............
It is caused by the process of rooting/modifying your device. Unless you use KNOX, don't worry.
[Q] How to disable
[A] Freeze or delete your KNOX & Security related apps/processes manually (using root explorer or titanium backup (pro) or use Synapse > Security > disable KNOX
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Synapse is the recommended and has everything you need
BATTERY TIPS
Try some (or combination) of the CPU MULTICORE features in Synapse:
HMP profile = Battery
Power Aware Scheduling (slight performance cost) = Enabled
HMP LITTLE Packing (slight performance cost) = Enabled
PEWQ (power-efficient workqueue) (slight performance cost) = Enabled​
Set A57 & A53 Interactive governor profile = Battery
Set Input-Booster for key/touchkey profile = Battery
Multi-tasking: enable UKSM & "low" or "quiet" profile (slight performance/battery cost)
Set all Advanced wake-lock controls to 1, except GPS. Set it to 4
Set WiFi wakelock control to 2 or 3
PERFORMANCE TIPS
Set A57 & A53 Interactive governor profile = Performance
Set A57 & A53 Interactive governor = Turbo Mode (battery cost)
Once in a while:
Optimize Databases
FSTrim​
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use a stock UNMODIFIED ROM for your device variant
No tweaks, Xposed or other CPU control apps installed
ASV_GROUP (ALL DEVICES ARE NOT CREATED EQUAL)
This is an example from my Exynos5420 source. Similar idea for Exynos420
http://forum.xda-developers.com/showpost.php?p=61579949&postcount=202
CAN I INCLUDE SkyHigh KERNEL IN MY ROM
Although I do appreciate your contribution here, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable any CPU MULTICORE options in Synapse
Disable any Battery profiles in Synapse. Set to default or Performance.
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
* [Christopher83]
This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature,
set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page
writebacks when the system is active (screen on)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's patch:
https://github.com/franciscofranco/mako/commit/34d79548cf16b69c7d0154836018e7f258a22947

TCP/IP NETWORK SECURITY
* Thanks to zeppelinrox & V6SuperCharger
Hardening the TCP/IP stack to SYN attack
Bump up tw_buckets in case we get DoS'd
Ignore pings
Don't cache connection metrics from previous connection
Don't pass traffic between networks or act as a router
Enable spoofing protection (turn on reverse packet filtering)
Don't accept source routing
Don't accept redirects

CHROMECAST - STREAMING PROBLEMS
* Thanks to @AtLmd Post
Lock screen MUST be enabled (simple screen lock swipe) I don't know why but it breaks the chromecast app's ability to resume smoothly if switched off
Synapse > Network > DTIM (both screen ON & OFF) = 1
Synapse > Network > WIFI Power Mode (screen OFF) = FAST

Here you are... Thank you for coming man.
Note: (G928C) This kernel is amazing. I have been using for long time. 95K antutu 6b5 score, 75k antutu 5.7.1 score, 6H sot with non-stop usage And see my other other comments, post #352 in:

On the second post there is a change log spoiler, you can see that there's support for the F C G I variants only, nothing mentioned about T or 7, most probably won't work as these are quite different
-=-=-
The kernel performs perfectly, I'm not keen to adjust any of the settings in synapse for now, default is rock stable and smooth, battery drainage looks great as well

v2.5 released
v2.5 update for SM-G928-C / F / G / I device variants
Check out the change-log in Post #2.
NOT TESTED. I DO NOT HAVE YOU DEVICE !
XDA RULE #1 'SEARCH BEFORE POSTING". Please READ Posts #1-3 BEFORE flashing !!
Please CLEAR SYNAPSE DATA before flash: device settings > Applications > Application manager > Synapse > force stop > clear data
Have fun

Help & FAQ
THREAD RULES & PROTOCOLS FOR THIS DEVELOPMENT THREAD:
I might not have your device variant and or able to reproduce your "issue". With this in mind, without providing as much information as possible, and resetting your device to a stable unmodified baseline, any potential troubleshooting or logs could be meaningless. So please follow the guidelines set out below. Thanks
BY POSTING YOUR ISSUES IN THIS THREAD, YOU ARE AGREE TO HELP YOURSELF FIRST BY PROVIDING INFO REGARDING:
Code:
1. DEVICE MODEL ?
2. ROM and firmware version (build number, boot-loader etc) ?
3. EXACT steps taken to reproduce YOUR issue
4. Screen-shots (if applicable)
5. Did you read Posts #1-3 completely?
6. Did you search the thread, XDA or GOOGLE?
7. Did you follow the install instructions EXACTLY?
8. What was your previous kernel?
9. Do you have any other known kernel tweaking apps, scripts or mods? ([B]remove them[/B]). [COLOR="Red"]This includes Xposed etc[/COLOR]
10. Try older kernel (if available)
11. Factory reset ?
12. Try latest stock [B]UNMODIFIED[/B] firmware (without custom ROM - if you have installed) and factory reset
13. Delete your ROM BusyBox (kernel uses it's own in /sbin)
ONLY IF YOU HAVE TRIED SUGGESTIONS ABOVE:
Turn on logging in Synapse and save logs AT TIME OF ERROR. AND post together with ALL the above information.
ELSE, DON'T WASTE MY TIME, YOU WILL BE IGNORED AND/OR POST REPORTED !!
THANK YOU :good:
NO FAST CHARGE
If using the pathetic original cable, try disconnect and reconnect the USB cable whilst power is still turned on to the charger
Use a thicker / better cable, will work every time (ie. Note4 OEM cable)
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
I will not build for any device that I can not compile using SAME source, personally test method or debug. Some device variants can compile with same source.
Sorry. I don't have the spare time for any more variant support.
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue
Three choices:
Device > settings > applications > Synapse > force close & wipe data and REBOOT
OR
Remove your ROM busybox from /system xbin and /system/bin (Synapse will use the kernel busybox in /sbin).
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
OR
Try install a different busybox
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
Synapse or BACKUP/RESTORE ISSUES
It's a ROM busybox or sqlite3 compatibility issue
Remove both your ROM busybox & sqlite3 from /system xbin and /system/bin (Synapse will use it's own from kernel /sbin).
Device > settings > applications > Synapse > force close & wipe data
Reboot or re-flash kernel as per Installation Instructions
BACKUP & RESTORE
DO NOT restore profiles from different kernel version
Refer to THIS post for "how-to" screen-shots
Refer to THIS post for a "how-to" video (thanks @aldoblaga )
LOADABLE MODULES AREN'T WORKING
Check your /system/lib/modules directory. Are any ____.ko present?
Did you flash a ROM or wipe the system partition at any point? Doing this will remove them !
Re-flash the kernel will install the modules.
If modules aren't installed after flash, then re-flash and manually mount system in recovery first.
You can check running modules in terminal with:
Code:
lsmod

CPU POWER CONSUMPTION
The Samsung Exynos 7420 Deep Dive - Inside A Modern 14nm SoC (by ANANDTECH - Andrei)
F2FS SUPPORT
It's not needed. You wouldn't see any difference or measure much, if anything. Not worth the potential trade-off. This is not eMMC anymore
http://bgr.com/2015/03/17/galaxy-s6-storage-benchmarks/
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.
CM SUPPORT
Read Post #12
"Unauthorized actions have been detected, reboot to undo changes"
As it's a common warning found with all KNOX enabled android devices, you would have found the answer by Google search and also that it is actually unrelated to kernel and also unrelated to this kernel development..............
It is caused by the process of rooting/modifying your device. Unless you use KNOX, don't worry.
[Q] How to disable
[A] Freeze or delete your KNOX & Security related apps/processes manually (using root explorer or titanium backup (pro) or use Synapse > Security > disable KNOX
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Synapse is the recommended and has everything you need
BATTERY TIPS
Try some (or combination) of the CPU MULTICORE features in Synapse:
HMP profile = Battery
Power Aware Scheduling (slight performance cost) = Enabled
HMP LITTLE Packing (slight performance cost) = Enabled
PEWQ (power-efficient workqueue) (slight performance cost) = Enabled​
Set A57 & A53 Interactive governor profile = Battery
Set Input-Booster for key/touchkey profile = Battery
Multi-tasking: enable UKSM & "low" or "quiet" profile (slight performance/battery cost)
Set all Advanced wake-lock controls to 1, except GPS. Set it to 4
Set WiFi wakelock control to 2 or 3
PERFORMANCE TIPS
Set A57 & A53 Interactive governor profile = Performance
Set A57 & A53 Interactive governor = Turbo Mode (battery cost)
Once in a while:
Optimize Databases
FSTrim​
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use a stock UNMODIFIED ROM for your device variant
No tweaks, Xposed or other CPU control apps installed
ASV_GROUP (ALL DEVICES ARE NOT CREATED EQUAL)
This is an example from my Exynos5420 source. Similar idea for Exynos420
http://forum.xda-developers.com/showpost.php?p=61579949&postcount=202
CAN I INCLUDE SkyHigh KERNEL IN MY ROM
Although I do appreciate your contribution here, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable any CPU MULTICORE options in Synapse
Disable any Battery profiles in Synapse. Set to default or Performance.
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
* [Christopher83]
This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature,
set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page
writebacks when the system is active (screen on)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's patch:
https://github.com/franciscofranco/mako/commit/34d79548cf16b69c7d0154836018e7f258a22947

Intitial release v3.9+ beta
Intitial release v3.9+ beta for SM-G928-P device
Check out the gitHub Change-log (link in Post #2).
Not personally tested > I have a SM-N920C
(If installed) Please CLEAR SYNAPSE DATA before flash: device settings > Applications > Application manager > Synapse > force stop > clear data
DO NOT restore profiles from older versions or other kernels !
XDA RULE #1 'SEARCH BEFORE POSTING". Please READ Posts #1-3 BEFORE flashing !!
BUGS:
Disabling "Turbo Mode" will screw up frequency scaling. So if you have disabled any time, you need to REBOOT !!
Changing Interactive governor profiles when Interactive is not used, will result in Synapse display errors. Nothing to worry, no need to change the profile if Interactive it not used !
Have fun

I have not personally tried it but i have read in a couple areas that it has worked. Do a little digging and you should find some answers

Hi, I found some comments, but with other ROMs, not this one. Could you let me know who said it? I would like to contact them..
Thanks!!

[Z00L][KERNEL]Enhancements For Increased Battery Backup

Disclaimer & Notes
I bear no responsibility towards any failure or malfunction of your device, use my kernels at your own risk.
I have no time or resources for support of any kind whatsoever.
The kernels are for my own use, recompiled from original boot images of respective roms, with the objective of prolonging battery backup, not performance.
The kernel features are compiled in only, meaning not optimized at all, you must use Kernel Adiutor to set the right options to achieve desired effect, see post #2
Yes, they work with XPOSED! (marshmallow only), but xposed modules should be enabled & configured ONE-BY-ONE-then-reboot-phone to take effect.
If wireless or sim cards are not detected after enabling some xposed modules, simply restart phone, or turn on-3mins-off airplane mode, or revert your xposed module settings (gravity-smart radio in particular)

EDIT: the settings above is not 100% tuned, but it works, there's no stutter either (during idle, 1 core should be 200-400MHz, by right, it should stay 200MHz all the time during idle, this is affected by timer_rate 46666, which does NOT stick at all, may need to set manually each time at boot). To get the proper value of timer rate, increase or decrease by 5000, it's base value is 30000, u can start from there. I simply chose 46666 coz it hovers less.

Thanks for this amazing work. Will flash the kernel right now on cm13. I tried optimising cpu governers with one of the guides in nexus thread, but they all proved vague as a simple touch is boosting all cpu cores to their max. Also 'stop perfd' command in terminal did helped a bit to limit it but then, the performance was stuttering. A big thanks for this kernel. Will flash and post the results.. ??

hotplug autosmp totally disables touch boost by its very nature

probably next week, no guarantees though.
I need to work on getting gpu idler functional. the idler works at all screens but not at screen off.
gpu frequencies
200Mhz, 310Mhz, 400Mhz
current gpu idler implementation which I tried:
during idle, the gpu should rest at 200Mhz, yes this works but the moment the screen goes off, it shoots back to 310Mhz and stays there.
try it on your current rom, at adb shell
Code:
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 ;
observe the asterisk *, that's the current gpu speed,
then try using the phone, touch menus, launch apps etc, see the * switch to different speeds, then check idle speed
Code:
From : To

Awesome kernel man. Thanks. Been using it on cm13 since yesterday and I must say the battery savings were significantly improved without compromising performance at all. No stuttering at all.
Will try it on RR N today.
BTW, I have a doubt, in above_highspeed_delay and target_loads, the first frequency written in OP is 100Mhz but cpu frequencies in Z00L starts from 200Mhz. So what's the significance of putting these values of 100MHz?
I know little about CPU Gov tuning and I/O scheduling but whatever I found on searching over XDA for I/O schedulers is, Deadline to be better I/O Scheduler with following tunings-
fifo_batch 4
front_merges 1
read_expire 500
write_expire 3000
writes_starved 3

RR Nougat - yes, check 1st post under section file names & roms
The truth about kernels and battery life
Not sure about other roms, you could test the kernel via fastboot
Code:
fastboot boot testkernel.img
This will boot the test kernel one time, your original kernel remains intact, you could check the features & whether it works for you.

[GUIDE] Advanced Interactive Governor Tweaks; Buttery smooth and insane battery life! (Old Guide)
What I remember: 100MHz is for the transition of sustained cpu loads of at least 60ms before crossing into the next frequency, while 200MHz is the cpu frequency stepping. Honestly speaking, if you go through the 2 guides above, you'll notice our cpu speed range is too small (200MHz > 400MHz > 533MHz > 800MHz > 998MHz).
You could replace it with the standard speed steppings ie 200 > 400 > 533MHz.
If you find better performance of any sort, pls post the settings.
Z00L battery may not be enough for my usage, no matter what I do, and I prefer not to carry a powerbank daily. I might get a Xiaomi Mi Max 4850 mAh and use Z00L as a backup. the Mi Max is just $70 extra, heck a 10,000 powerbank already costs $20, and the Mi Max gives 6.4" IPS, 3GB ram, 2 more power cores, plus the big battery. I could use at least 2 days w/o charging.

Been using the kernel and suggested settings since yesterday on CM13 Snapshot and the battery life and performance of this is a beast! great work mate...got roughly 3:30hs SOT and lost only 47% of juice.

You can try. If any prob occur.
Just flash the boot.img from the xosp rom zip file to revert the effect

You should add for stock rom to.

RR Nougat - yes, check 1st post under section file names & roms
The truth about kernels and battery life
Not sure about other roms, you could test the kernel via fastboot
Code:
fastboot boot testkernel.img
This will boot the test kernel one time, your original kernel remains intact, you could check the features & whether it works for you.

I tested in for XOSP ROM and got "Okay" message at the end. I tried to flash with TWRP Recovery but its not finding Winzip file in directory. I tried to convert into .zip file which came as "boot_m003_RR-N-v5.8.0-20161222-Z00L.7z.zip" and failed while flashing.
Also i tried with this command in fast boot mode: fastboot flash boot_m003_RR-N-v5.8.0-20161222-Z00L.img but it's not working.
can you plz make .zip file ?
