HOTPLUG CONTROL, GOVERNORS, SAMPLE CONFIGS:
Thanks to n3ocort3x
With cpuquiet + load stats governor u get a brilliant battery life while keep it snappy.
I recommend leaving the governor on load stats (hotplug depended on load) to get the best results.
If you want to keep it balanced, and yeah, most users want that:
governor: smartmax
cpuquiet governor: load_stats
If you want ultimate performance:
governor: interactive (up treshold 65) or smartmax (lower tresholds)
cpuquiet governor: load_stats
SMARTMAX GOVERNOR

Thanks to bedalus
This is just for the record, and for those interested. The previous version of Preservative worked like a combination of smartass and conservative. It would scale straight up to the optimum frequency if there was any load (like smartass), then scale up one step at a time (like conservative) if the load was above the required threshold. This worked pretty well, and helped keep the frequency low. But sometimes it was keeping it low for too long, and a few users (myself included) noticed occasional hangs, presumably caused by a pile up of critical code that didn't get executed in time.
To improve responsiveness, but keep the frequency as low as possible was quite a challenge. I took the existing logic and chucked most of it in the bin...
(Remember, it's keeping the frequency low, and not UV that saves power - read this thread, especially post #2 for more background on this issue)
...what came to replace it was a fairly original hybrid, inspired by ondemand. Ondemand works by jumping to the top frequency when there is any load. This is usually overkill. So, you might have been at 100% CPU utilisation at 384MHz, so ondemand will jump straight to 1512MHz. However, when it gets there, the utilisation is now only 30%, so it will scale down to 486MHz.
Preservative now works a little like this. Whatever frequency it is currently at, if the utilisation hits 100%, it will scale up. But scaling up to max like ondemand? In the example above, this was the worst kind of overkill. Scaling up to max just to find scaling up one step would have been sufficient. But do we need to scale up one step, or as many as possible? There's no way to know for sure. You have to scale up before you can measure if the extra CPU cycles were enough or not.
This issue is what Preservative attempts to overcome: if the load is high, it will scale up, but not always to max. Let's label the frequency steps: 384=A 486=B 594=C 702=D 810=E 918=F 1026=G 1134=H 1242=I 1350=J 1458=K 1512=L
Conservative would take 11 calls to the governor to get from A to L, if L was required. Ondemand would go straight there. Ondemand is often overkill, conservative is often underkill. I'd like a compromise. Here's what Preservative would do:
Code:
L <- 4th step selected by preservative
K <- 3rd step selected by preservative
J <- 2nd step selected by preservative
I
H
G <- 1st step selected by preservative
F
E
D
C
B
A <- sat here until there is load
It splits the difference between whichever frequency it is at and the top frequency, and jumps there. If it is still under high load, it will do it again. So if it is idling, then needs to get to the top, it takes three more calls than ondemand, but seven less than conservative. Not only that, but it has also skipped over a large chunk of the slower steps that conservative would crawl through.
Scaling down also works in a similar way. Preservative will work out what step would be sufficient to manage the load, then jump halfway to that step on the first call. This is because, unlike ondemand, there is no down-threshold. Preservative will scale up when the load exceed the up threshold, but as soon as this is no longer the case, it will start attempting to scale back down to save power. It does not wait for load to reduce to drop below a certain point. Loads fluctuate. If went straight back to A, only to come back back to L, it would have to scale through G J and K again. However, dropping to G then D then B before A means if it does have to scale back up towards L, it doesn't have as far to climb, meaning less calls to the governor, and that the best step can be achieved quicker.
There has also been an adjustment to the up threshold. When the device is idle, the up threshold will automatically adjust to be more relaxed about scaling up. This means while the device is idle (e.g. when you are just reading some text) it becomes increasingly sensitive to changes in demand. When you touch the screen it will extremely responsive.
Conversely, when the device is hitting the top frequency, the up threshold will become increasingly strict. So if you are gaming, and putting a lot of load on the CPU, it will aim to be as efficient as possible, and only scale up if it really has to, to ensure that no cycles are wasted at these high power hungry frequencies.
Whenever it goes from hitting L to hitting A, or visa versa, the threshold will reset to default. The sysfs location of this tunable remains at:
Code:
/sys/devices/system/cpu/cpufreq/up_threshold
It will accept values of up to 127, higher being more power-saving. The default is 100, but editing the file changes this value. If you want to use a different value on a permanent basis, add the line
Code:
[B]echo 84 > /sys/devices/system/cpu/cpufreq/up_threshold[/B]
to /etc/init.d/00config
and it will then restore your setting of 84 (or whatever) every time you reboot. Remember it will be overwritten if you flash updates to the kernel, so make a copy of your edited file. However, I believe 100 is a pretty good default.

Its a kernel not a rom. What do you need screenshots of?

My bad. too excited with my new Yureka that not paying attention to anything

flashed this kernel and used it for 5 hrs.
Good BATTERY command.
i attended a con-call for 90 plus minutes and battery drained only 5%
No lag while using basic games like clash of clan or clash of lords
Issues identified
screen black out while on call, you cant control your calls like add new call or check text while you are on phone calls. but no issue in voice and reception.
while making call you cant drop call as screen goes black out.
No heating issue as far i observed.
colour reproduction is good.
seems need little fine tune can make this kernel a must install.
All the very best to develops

you are talking about proximity sensor issue , is it right?
Sent from my AO5510 using XDA Free mobile app

Review after using a whole day.
1. First & best intelli_plug driver - loved the live and smooth activation and deactivation of cores acc to load. only single core runs while using light apps (whatsapp,hike,tapatalk etc) i.e. full utilization of a single core.
2. Highly customizable using the FauxClock pro app.
3. cpu temp was usually higher (50-60 degrees) than my last kernel (Tz).
4. As @sunilnair007 posted the screen goes black while call. But one thing i noticed was when i press just at the side of proxi sensor the screen wakes up Exactly same as the Yureka proximity issue but on all other kernels the proxi was working fine on my phone (stock, thunderzap)...
5. i didn't used the phone for an hour or so i.e. phone was in deep sleep the i tried to wake up the device by the power button several times but finally had to remove battery and put again and booted the device :c
and after turning on the battery was 12% (earlier it was above 75%) and it was increasing by itself >.> battery usage graph ss --- i.imgur.com/y9QCyCz.png
and after keeping it turned off for sometime and restarting the battery got stable at 46% and started decreasing as per usage. (so got much less battery backup)

How to make best use of it.
Installed this kernel.
However, it seems very complex to make best use of it by a person like me who is not used to Custom Kernels. Before this I have used ThunderZap2, and Xcelerate, without much of tweaking. In Xcelerate for example, I found that different cores where shutting down by default. Here all the core are working by default. Obviously with this Kernel it seems I will have to do some tweaking.
I have also installed Kernel Adiutor as recommended in OP. However, information on recommended setting is too sketchy.
Would like to more detailed information as how to tweak / set this kernel to make best use of it.

tons of thanks to you bro... for kcal addition
Bro thanks a lot for adding kcal colour management to YU yureka..
Very nice bro..
One thing bro the hotplug is only working with 4 cpu of first cluster only...
I'm using kernel audiutor beta...
And please rommended any setting to run it cooller because comparing to other custom kernel it run little high temp..
Otherwise working grate.....

[KERNEL][3.10.71][KCAL] Velocity v1.1
Seems developer worked hard and results are visible.
No complaints so far testing since morning.
Need 2 days time to give a stable review.
Best wishes and please keep this spirit intact

Noticed this too. Pressing the volume buttons once/twice, when it is unresponsive, wakes it right back up.

Firstly, I'll try to simplify the recommended settings.
Secondly, hotplugging is not enabled by default.
Enable it by going to CPU Hotplug in Kernel Adiutor and enabling Intelliplug.

Set the Intelliplug profile to Eco Conservative/Eco Performance to hotplug upto 7 cores.
I'm looking into the cluster problem as mentioned.
To run cooler, try reducing the max frequency.

The issue is that if you set performance profile to "Power save", gov "ondemand" & min frequency lesser than 500MHz, phone sleeps to death & you have to hard reboot to get back on. Its a known bug and is present in stock kernel too. Check if settings i stated are the reason for you. Doesn't happen with "Interactive" because it never scales lower.

@neomanu , Do I need to wipe cache and dalvik cache while flashing this kernel over any ROM. Also I have flashed a custom kernel previously and now I want to flash this, so Should I simply follow your instructions or need to wipe something.

No Need to wipe anything. To give u extra boost you can wipe dalvik cache which will rebuild cache again and its always good. no need of cache or data wipe

Is this kernel support's volte?

[Kernel][5.x.x][ArchiDroid-GCC5.2] DatKernel for i9082 [r21][O3 & Ofast][02122015]

​
What is it?
DatKernel is a fully customizable Kernel, with lots of new options that our Grand was never supposed to have. Have you ever thought of the perfect balance between battery life and craze performance? Here we go.
I first started compiling in October this year, inspired by @codekidX kernel and decided to build my own Kernel. I struggled some time to learn how to and implement my first functionalities and my first toolchain was Linaro 4.9 from @Christopher83. Since then, I've built hundreds of times with dozens of toolchains and, since everything is pretty much stable and different from other kernels around SGGD development, I had to share with you guys to further improve this kernel.
For me, the biggest problem were related to constant reboots caused by overflow in RAM or by incorrect execution when I started many apps. Couldn't open my maps with bluetooth playing music on my car and *BUM*, rebooted. Also, the performance was a little laggy sometimes, due to lack of upstreamed source. So let's waste no more time:
List of features​
Toolchain and Compiling
Compiled with ArchiDroid's 5.2 toolchain, thanks to @JustArchi for his amazing job. GCC5.2 is very very stable.
Most of the kernel compiled with -O3 flags, but a lot of parts are compiled using -Ofast (goodbye O2 and Os hehe).
Using all the graphite optimizations that were possible to our phone, along with cortex-a9 tweaks.
Kernel Features
Dynamic management of dirty page writebacks, thanks to @faux123
Asynchronous file sync, thanks to @faux123
Dynamic filesync, thanks to @faux123
zram is enabled. It was backported also from @faux123 mako Kernel, and I did some commits to adapt it to 3.0.101, to lz4 support and to Zsmalloc.
Optimized ARM RWSEM / CRC32 algorithms, thanks to @coderdoid
Implemented frandom, thanks to @Ryuninferno
Updated Kernel Freezer and implemented Input Touchboost, thanks to @franciscofranco
Backport LMK RB trees from Motorola, thanks to @faux123
Lots of commits from 3.4.x and 3.12.x which came from CM's repos and @DespairFactor and @myfluxi. Some of them were crucial and obviously 3.0.101 lacked support of it.
Drivers like thermal, staging (LMK, binder, logger, gpio) and others were updated to last on CM-13.0, with some backports.
Ultra KSM implemented and enabled (UKSM)
vmpressure updated to CAF.
Boeffla-sound, thanks to @Andip71
cgroup_timer_slack and also dynamic cgroup_timer_slack management.
Boottime (it's useful for viewing boot time, implemented just because...). Thanks to @k2wl !!
oom_kill.c from @faux123 mako Kernel. This was a little hard to backport, but now I see how big the changes are until 3.4.xx
Zsmalloc which proved to be very useful when replacing Xvmalloc (the latter seems to be depracated).
Check my GitHub for much more awesome stuff...
Governors and I/O Schedulers
Updated and tweaked BFQ, SIO and DEADLINE. Also comes with CFQ, Noop, ROW and Sioplus.
Governors updated to @dorimanx version: ondemand, alucard, darkness, impulse, intelliactive, performance and zzmoove.
Interactive governor was updated according to @myfluxi repo and blu_active is the same used on @eng.stk kernel.
Do you want to see any governor here? Please request and I'll try to implement it!
CPU Hotplug drivers
intelliplug (aka intelli_plug) is implementes and working fine with intelliactive, with default options enabled.
zzmoove also offer lots of hotplugging options which are VERY stable, not a single random reboot or freezing during my usage with it.
Do you want any other CPU HOTPLUG driver? There are lots of options, if you want any of them, request it.
Attention
I'm not experienced as a Android Dev, as you can see most of features here were backported or upstreamed.
You can request features, but don't expect them to be implemented asap, because there are lots of tests to do. Please don't request DT2W and S2W, because they do not work properly on our phones (too much waste of battery for small benefits).
Also, if I have to backport or Upstream anything, be sure that is not as easy as it seems, cause 3.0.101 is pretty outdated nowadays, but we can't go much further than this.
Disclaimer​
If your phone is bricked, exploded, vanished or something like this after installing this kernel, it's not my responsability. I'm sharing with you my personal builds and you're using at your own risk.
Be sure that I'll help you as I can, but this is supposed to be a kernel adapted to my usage and may not work for yours. Follow the instructions correctly and don't forget to hit thanks if you liked the initiative.

This part is still under construction, so bare with me!
How to customize the governors?
Most of the governors on XDA are based on some of the basic ones. As, I'm not the creator of any of these governors, I will only show you my personal recommendations and some links for you to read more. Let's go!
Interactive-based Governors
This are the new ones, which derived from very updated code, which is said to replace ondemand on the future. I really like these governors, as they're blazing fast and battery-life is almost the same as default ondemand. They're impulse, intelliactive, blu_active and interactive:
interactive: Upstreamed to lates on Code Aurora Forums (CAF), it is a very fast governor. Scales depending on load and goes really fast from minimum to max frequency. The battery is "OK" with this one, and you can tweak it to become exactly as you like, just by following this thread instructions: [GUIDE] Advanced Interactive Governor Tweaks; Buttery smooth and insane battery life!, by @soniCron.
RECOMMENDATION: I've tweaked it for best performance already, so give it a try on default.​
intelliactive: More performance focused than interactive, but achieves a great balance between battery-life and performance. You can tweak it using the same thread by soniCron that I told you in interactive.
RECOMMENDATION: The frequencies are on par with my i9082 common usage, and it fells a little better than interactive, but they're almost the same on benchmarks.​
impulse: This one is focused on battery-life and works just fine, with some lag here and there (not that it really lags, lil stutters). You can tweak it using the same thread by soniCron that I told you in interactive.
RECOMMENDATION: Again, this one is tweaked for our i9082 and can save some battery if you use it on default.​
blu_active: @eng.stk made this one, it's probably the fastes on interactive-based, but it's not very stable on my phone. You can try for yourself and see if is there any random reboots.
RECOMMENDATION: For now, you can try it, it's very snappy and smooth but not that stable. See if default works for you.​
Ondemand-based Governors
Apart from being a little outdated, they still work great and bring really impressive results under the table. The governors ramp up and ramp down in defined steps, according to demand, but if you're multi-tasking, it stays on very high frequencies. The governors are: alucard, darkness, nightmare and ondemand.
ondemand: Not much to say. It's the default governor because it's very stable and you can find much information about it on this link: CPU Governors, Hotplugging drivers and GPU governors
RECOMMENDATION: Use it by default, rock-solid stable.​
Darkness: It works fast and is a new gov. Liked it, it's good by default.
RECOMMENDATION: Use it by default, may be stable.​
Nightmare: This one originated Darkness, and is probably the same with bigger code.
RECOMMENDATION: Same recommendations as Darkness, use it by default.​
Alucard: Pretty impressive governor, made by @alucard_24 and maintained by @dorimanx.
RECOMMENDATION: Default is OK, it's the best under ondemand-based governors.​
Conservative-based Governors: zzmoove
Maintain the phone on lowest possible frequency whenever possible. The only governor 'round here is zzmoove and DUDE: it's great. Thanks to it, I have a Crazy-smooth experience and awesome battery-life, so I really liked the way it works.
zzmoove: Created by @ZaneZam and maintained by him and @Yank555, this governor focus is to maintain frequency as low as possible. In order to do that, it limit frequencies whilst the screen is off or hearing music, in example, so it's very adaptive to your usage if you tune it right. It has 9 profiles, which are described below, on "Click to show content"
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (1)'def' -> Default -> will set governor defaults -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (2)'ybat -> Yank Battery -> a very good battery/performance balanced setting -
* - DEV-NOTE: highly recommended! -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (3)'ybatext'-> Yank Battery Extreme -> like yank battery but focus on battery saving -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (4)'zzbat' -> ZaneZam Battery -> a more 'harsh' setting strictly focused on battery saving -
* - DEV-NOTE: might give some lags! -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (5)'zzbatp' -> ZaneZam Battery Plus -> NEW! reworked 'faster' battery setting -
* - DEV-NOTE: recommended too! -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (6)'zzopt' -> ZaneZam Optimized -> balanced setting with no focus in any direction -
* - DEV-NOTE: relict from back in the days, even though some people still like it! -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (7)'zzmod' -> ZaneZam Moderate -> NEW! setting based on 'zzopt' which has mainly (but not strictly only!) 2 cores online -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (8)'zzperf' -> ZaneZam Performance -> all you can get from zzmoove in terms of performance but still has the fast -
* - down scaling/hotplugging behaving -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (9)'zzinz' -> ZaneZam InZane -> NEW! based on performance with new insane scaling active. a new experience! -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (10)'zzgame' -> ZaneZam Gaming -> NEW! based on performance with scaling block enabled to avoid cpu overheating during gameplay -
* ------------------------------------------------------------------------------------------------------------------------------------------
* - (11)'zzrelax'-> ZaneZam Relax -> NEW! based on moderate (except hotplug settings) with relaxed sleep settings -
* ------------------------------------------------------------------------------------------------------------------------------------------
RECOMMENDATION: I selected for default "zzinZ", profile 9, because it really is what I want: lagless when using, low frequencies when not using. And I got it, so I suggest you to have a look.​
What about I/O Sched?
Well, I've never worried much about I/O sched. When pawitp put BFQ as default on CM12.1, I thought that it was really good, but really unstable as well. The two I like the most are: SIO and Deadline for general usage (multitasking). If you like to play heavy games, use ROW. You can try the others and actually read this article that talks everything about I/O Schedulers: I/O Schedulers - Android Modders Guide
Damn, need that Hotplug asap!
i9082 phones, have lots of power and sometime doesn't need all cores online. That's where come hot-plugging, some cores can be turned off with no overhead or noticeable lag.
The options are: intelli_plug and zzmoove hotplugging feature.
intelli_plug: The first option is a widely spread hotplug driver, made by @faux123 and it works great for what it's doing. I recommend tweaking it for you needs and the best governor to integrate with it is intelliactive, made by faux123 as well. It'll actually waste battery instead of saving if you are a power user that loves lots of multitasking, because it'll be constantly turning CPU1 on and off. Note that while using this, make sure your tasks with Screen Off are not that big, because your phone must handle that with just 1 core, which can lead to a kernel freeze (than you have to reboot). It's recommended if you usage is very light and you want a 2 days long battery.​
zzmoove hot-plugging: The second one is a more concise approach, because you'll need only the governor to handle hot-plugging. Here you can activate the hotplug on governor's tunables (change to disable_hotplug = 0 and disable_hotplug_sleep = 0) and it works by shutting down CPU1 whenever the load is not that big. Again, if you're a power user, beware that this can actually shrink you battery time, so use hotplug if you doesn't need much complex things to be done when screen is off.​
frandom - Don't forget to use this script in your init.d folder
Create a new file named "00frandom" and in order to frandom work, you need to use this code:
Code:
#!/system/bin/sh
# Script to launch frandom at boot by Ryuinferno @ XDA
insmod /system/lib/modules/frandom.ko
chmod 644 /dev/frandom
chmod 644 /dev/erandom
mv /dev/random /dev/random.ori
mv /dev/urandom /dev/urandom.ori
ln /dev/frandom /dev/random
chmod 644 /dev/random
ln /dev/erandom /dev/urandom
chmod 644 /dev/urandom
My Recommendation​
zzmoove really got me, because it works like interactive but it tries to always lower the frequency, which is great. Apart from that, intelliactive is very fast, almost the same as interactive. So, for craziness zzmoove and for performance, intelliactive (UNDER CONSTRUCTION, JUST A QUICK PREVIEW).
### Anything else there is to customize is in Kernel Adiutor, which is a great app thanks to @Grarak

Download here!
DOWNLOADS​
First things first: how to install?
Backup your EFS partition and do a full nandroid of your system. Never did the latter, but my backup of EFS partition saved me multiple times when I was a noob in flashing.
Download last version which will be attached on my GitHub Release page (download the zip). Will try to attach it to the thread here as well.
You're installing for the first time? Factory reset your phone and install the lastest version of CM12.1 from @pawitp. Be sure to do this before anything weird happens. You're advised! (the reason is that when you flash different kernels, sometimes they're on different kernel version on crucial parts, which leads system to incompatibility)
Already installed once? Just dirty flash it then and profit.
Reboot your phone.
Lemme download this, bro!
FOLLOW THE SETTING UP HERE /\. It's the same for all kernels you've used, but please, EFS partition backup is a must.
The last version will be on my GitHub's release page, on this link:
To download it, click on "DatKernel-rXX.zip" under Download tab on Latest release. Trouble downloading it? PM me so I can send it to you!
>>>> CLICK HERE TO DOWNLOAD <<<<​

Thanks, nice to see a new kernel.
Will try it when ready

@RichyE with you want to try it now, I just uploaded r20 to GitHub, give it a shot!
https://github.com/Neves4/DatKernel/releases/tag/r20
Download "DatKernel-r20.zip" file.
And for now, I'm having crazy smooth results with zzmoove, try it
Oh, and remember to have CM-12.1 ready to reflash, just in case something goes wrong.

SWAP
is this swap enabled(for swapping the sdcard memory to increase the ram)??

It is enabled on configs, but when I type "free" in terminal it shows no swap device being used, which is weird. Can you try it and see what happens when you type free in terminal?

Flashed it on RR first boot gave problem, had to pull batery but after that it worked.
Even a couple of reboots went smooth

@RichyE is it working OK now? I'm sorry to hear you had trouble...
Have you tried the new govs?
Thanks

@neves4 It's working now without a problem
At the moment trying zzmoove and Sioplus

Zzmoove (or kernel??) giving a little trouble I think.
Sometimes the phone doesn't switch on and I have to pull battery.
Switching back to my originel kernel for the moment and will try another time.

everything was smooth but YouTube app hangs a lot!

I just flash it normally and using zzmove and sioplus and no problem it works very smooth :good:

I am going to try your kernel soon but is it stable enough to be used as a daily driver????
And one request if you don't mind can you develop ROM for our device with marshmallow support???

@neves4 is it kit kat compatible?

I was using zmoove governor and sioplus as the io scheduler. I didn't know what hot-plugging was, so didn't mess with it. appreciate your effort man.

Do you plan to make it compatible for aosp 6?

hi
thanks for the kernel..will trry it soon.
i have one doubt.
zzmove needs hotplugging and as far as i know our kona platform restriced it in kernel code.
thats why RichyE have problems with zzmove.
anyways may be you have solved that..good luck...

Hey man, it's completely stable for me. Smooth, fast and with great battery, I'm using r20 with no random reboots for 120 hours, and I'm a power use (always using bluetooth, with 3G on and GPS on High Accuracy). If you want to be sure that it's going to work, do a clean install and install lastest CM12.1 that it'll be stable as a rock
And about the ROM with marshmallow support, I'm waiting until pawitp gets AOSP-6.0 stable, because there are some complications to make it work on our phones

Good question! I've never used KitKat, because I used to own an iPhone. Since this kernel is based on Frost Kernel source code, I'm almost sure it works on KitKat, and the others to 4.1.2. Can you try it and report back? Be sure to have a copy of the ROM you're using, because anything goes wrong, you just have to flash the ROM back.

Thanks for the answer
It's known that zzmoove has problems with big loads, so I think that when you were using YouTube, you were probably using other apps on background, which made system a little unstable. Can you try interactive or intelliactive and see if the same happens?

I would love to, but AOSP 6.0 is still not stable for our phones, as pawitp is still fixing some stuff. But as soon as everything is OK there, I'll be doing AOSP-6.0 compatibility patches if needed

F.A.Q. --
1. My WiFi doesn't works after flashing this kernel.
Extract wlan.ko from the .zip of kernel (located under system/lib/modules/) and place it in root/system/lib/modules/ overwriting the one already present there. Then, set the permission of the file to rw-r-r and reboot the phone. Use ES File Manager with Root Permission to do this.
OR
Place the .zip of the kernel in Internal Storage and then re-flash the kernel.
OR
Check free space in /system partition. Atleast, 25 MB of free space should be there in /system partition as less space prevents the wlan.ko file to get copied successfully.
OR
Flash the latest version of SuperSU.
OR
Change the ROM.
2. Which Android Versions does this Kernel supports?
AzurE Kernel supports Marshmallow and Nougat ROMs. However, not every Kernel Version supports every Android Version. Check Changelog of the specific Kernel Version before flashing it.
3. Does VoLTE works on this Kernel?
Yes, if the ROM supports VoLTE, then this Kernel will also support VoLTE. However, if the ROM doesn't supports VoLTE, then this Kernel won't too.
4. How long are you planning to continue development of AzurE Kernel for Yu-Devices?
As long as I have my Yu Yureka PLUS with me, I'll keep the development active.
5. I have a feature-request!
Well, feature-requests are accepted only when I find the said feature to be having some practical use or substantial positive effect. Whether I include the feature or not, is purely my decision.
6. Why don't you answer my queries? I have asked 10 times already!
It takes much time in developing and testing a Kernel. So, it is difficult for me to keep track of every query too. However, if your query is a genuine one (i.e., not a duplicate question or a question, the answer of which isn't present in the First Post or the Changelogs), then I'll surely answer it.
7. Kernel Adiutor shows blank space in Governor and Frequency Panel of CPU TAB.
When Core 0 gets disabled (due to Core Control or State Helper HotPlug), Adiutor fails to get Frequency and Governor information and hence shows 0MHz in Frequency Panel and Blank Space in Governor Panel. This is normal. In this case, if you need to change Governor or Frequency, then you need to disable Core Control or State Helper HotPlug as the case may be. After this, force close Adiutor and then re-open it. This will make Adiutor get CPU information again. Also, if you don't want to face this situation again, then disable HotPlug Boost Toggle (this will make the kernel to not disable Core 0 and hence, such situation won't arise).
8. The HotPlugs aren't working! After sometime, all the cores come online.
After manually changing the CPU Governor or Frequency, all the Cores will come online even if any HotPlug is enabled. So, you just need to re-enable any HotPlugs you were using in order to disable the Cores again.
9. My whole big Cluster is offline! I can't enable it anyway!
Well, my kernel uses Core Control v2.0 (built by me) and hence, it has the ability to disable the whole big Cluster (including Core 0) if temperature rises above 55 C. When the temperature comes below 55 C, the big Cluster is brought back online again. This is normal and is done to reduce heat. Moreover, if you don't want Core 0 to get disabled, then you can Disable the HotPlug Boost Toggle (available under CPU TAB).
10. The CPU Frequencies are locked. I can't change them. This is a very serious BUG.
I wouldn't call it an issue or a BUG. It is a feature. My kernel uses a Custom Thermal Driver. It reduces the Frequencies to keep the temperature of the Kernel within safe limits. Hence, sometimes, when the temperature is above a certain degree, the Thermal Driver locks the Maximum Frequency so as to lower the temperature of the SoC. However, in my kernel, everything is user-configurable. So, if you want more performance and can bear some heat, then you are free to set the Thermal Settings according to your preference. These settings are available under the Thermal TAB of the Modded version of Adiutor only.
11. I don't have a 1.5A Charger. Should I use Quick Charge or not?
Let me clear this in a simple yet detailed way.
To use ThunderCharge's 1250 mA value, one needs a Charger capable of supplying 1.25A. So, if you're using a 1A Charger and you have set 1250 mA in ThunderCharge, then it won't work. The Charging will only occur at a speed of 1000 mA which your Charger supports.
Similarly, Quick Charge requires a 1.5A Charger for it to work fully. However, this doesn't means that using a 1A Charger with Quick Charge will affect Charging Speed negatively. So, if you're using a 1A Charger, then Quick Charge will draw only 1000 mA.
As for the Dynamic Current Panel, it shows the Value requested from the Charger, not the Actual Value drawn.
BTW, if you are using the Stock Charge and Yu Yureka phone, then Disable Quick Charge.

Changelogs: -
*Now U can Turn off Core-0 - Device probably won't reboot anymore
*Boot using 5 cores. In Details, many users were facing bootloops, because, the kernel was configured to boot on all 8 cores, at max frequency, which was 1612MHz, so this drew a lots of battery power, and weak batteries resulted in bootloops. Remember, Splashloops(Device Looping at YU logo, no bootanimation) is most probably caused by lesser system space <25mB, U have to ensure a system space of 25mB, before reporting it here
*Alucard Hotplug - Added Alucard Hotplug, AND please, use only one Hotplug at once, Either AiO or Alucard;

Hello Guys,
Many of the YUsers were Complaining about "Battery Drain, Heating and Lagginess" faced, when using Oreo ROMs, e.g. - NitroGen OS, Nougat ROMs like Resurrection Remix etc.
So, I spared some time, looked into the matter and Finally, the kernel has been UPDATED!!!

* Its new features:
* 1. Full system scan:
* It automatically scans all user processes' anonymous VMAs. Kernel-user

*
* 2. Rich area detection:
* It automatically detects rich areas containing abundant duplicated

* 3. Ultra Per-page scan speed improvement:
* A new hash algorithm is proposed. As a result, on a machine with

* filtered out. My benchmark shows it's more efficient than KSM's per-page
* hash value based volatile page detection.
*
*
* 5. Misc changes upon KSM:
* * It has a fully x86-opitmized memcmp dedicated for 4-byte-aligned page
* comparison. It's much faster than default C version on x86.
* * rmap_item now has an struct *page member to loosely cache a
* address-->page mapping, which reduces too much time-costly
* follow_page().
* * The VMA creation/exit procedures are hooked to let the Ultra KSM know.
* * try_to_merge_two_pages() now can revert a pte if it fails. No break_
* ksm is needed for this case.
*
* 6. Full Zero Page consideration(contributed by Figo Zhang)
* Now uksmd consider full zero pages as special pages and merge them to an
* special unswappable uksm zero page
*Zen Interactive Tuning: Auto Tunes the kernel for responsiveness at the cost of throughput and power usage.
*Enabled F-Sync
*Decreased time to Enter Sleep Extensively
*Relaxed Governor is tuned a bit!!
*AluCARD HotPlug Updated to Latest Version
*Tuned for more memory

Is there a zzmoove governor in this kernel?

Will test for week with intelliactive governor and NFS magisk module. Will update again after a week. Thanks for the kernel!
AOD fixed by wiping cache and dalvik-cache

@darkness I just found this thread. If you are interested in adding more govs, I have the source to add the following (the below list includes default ones as well) to the Havoc-OS kernel, ie @kyasu LOS Kernel

I have seen a lot of people get excited about ZZMove. I think it is a LOT of effort to configure correctly, and if not configured correctly its really bad. And on top of that, I think the true battery saving advantages are over rated as compared to if you get Doze working correctly.

Which CPU governor has the minimum battery consumption

If you want the ABSOLUTE min battery consumption without compromise, then the Gov does not really matter. Simply set your max CPU to the lowest frequency available.
The real practicality is about selecting a gov that provides YOU the best compromise for how YOU personally use your phone. eg I don't use my phone for gaming, while others might.
My personal experience is that there are two main paths for battery consumption. Screen on and screen off. Screen on is heavily affected by Gov, so the most conservative you can bear. And if you are really committed for small gains, adjust the ramp-up etc
see:
https://forum.xda-developers.com/general/general/ref-to-date-guide-cpu-governors-o-t3048957
https://forum.xda-developers.com/showthread.php?t=1767797
https://forum.xda-developers.com/nexus-4/general/guide-android-governors-explained-t2017715
For screen off, then Doze becomes the controlling factor, BIG TIME! I got my phone into doze in 30 sec of screen off, and the battery consumption is brilliant!
To investigate your current state, see:
https://forum.xda-developers.com/showpost.php?p=79135309&postcount=74
That post and the following one shows the difference how my phone is either screen on or in Doze. As compared to a LOS device which sits in maintenance (a higher battery state) for some time after the screen is off.
Doze's deep-idle is your batteries lowest power state, apart from off
PS, not that it means anything, I personally run Tripndroid CPU Gov (and sched) based on how it is described and from personal checks where it appears to like the lower frequencies while still staying very responsive. It jumps around a bit which to me means it is attempting to find the the lowest appropriate freq, while some act more like a min-max, ie not the lowest appropriate, but min when not in use and max when in even the lowest use. I don't notice any lag.

I tried version 1.5, but it got stucked on splash screen and goes to download mode. Sometimes the system boots fine, but as soon as I shutdown my phone the problem persist again... I tried to reflash my rom and reflash the kernel but the same thing happens. I tried to wipe dalvik cache and cache, still the problem is the same. I'm using Havoc 2.7

A last_kmsg may help the dev decipher where its failing.

I've switched to the Impulse CPU Gov, as it appears to quickly scale down and like the lower frequencies and switch off (hotplug) other cores, while still being very responsive ie I haven't noticed any lags. It was created by the main dev who worked Oreo crDroid.
I *may* of also noticed that when plating music with the screen off, sometimes there was a stutter when using Tripndroid and switching songs, and I haven't had this occur with Impulse, as yet. I also have an app that momentarily switches the screen on between songs, to display the cover art, which I am sure wouldn't help.
It could be a random thing, but it looks good thus far.

just flashed, i do see more options for cpu frquencies but i don't see gpu frequencies like 100mhz or 600mhz???

Latest one cause bootloop in Havoc 9.0

Hi, i has benn flased last reléase, bootlock after reboot, somebody have this bug?
Thanks.
