FAQ
Q : With what ROM can I use this kernel ?
A : With any ROM based on Sony stock Marshmallow
Q : Your kernel isn't working / My phone isn't booting anymore
A : Read this whole post once more, search for your problem in thread and report it if you haven't found a solution.
Q : Can I install this kernel on locked bootloader ?
A : No ! This kernel is only for unlocked bootloader.
Q : Does this kernel include recovery ?
A : Yes ! You can access by pressing buttons when the led is lighting. Volume down to go to TWRP and Volume up to load recovery from FOTA..
Q : What are mpdecision and fast hotplug ?
A : This is what manage your cpu cores and decide which core will be online. Fast hotplug is a brand new hotplug that I wrote. See next post for more information

About Fast hotplug
Motivation
I wasn't convinced by show-p's msm_mpdecision nor faux123's intelli_plug ( I don't even talk about qcom mpdecision ). I also wanted to start working on a bigger programming project to learn more about kernel developing so I decided to write my own hotplug.
Main features
I tried to make fast hotplug the lightest possible, so that it consumes the less resources possible when it is not needed (mainly at idle). One of the second goals was to make it customizable.
How to use
Deactivate qcom mpdecision (Pimp my Z1 will do this automatically when you choose fast hotplug)
Activate fast_hotplug
Code:
adb shell "echo 1 > /sys/module/fast_hotplug/parameters/fast_hotplug_enabled"
Tune it to your liking
How to configure
Unfortunately, there isn't yet any user friendly application to configure fast hotplug. The only way to configure it is to manually edit the module files with adb or a file editor.
I modified Pimp my Z1 to be compatible with fast hotplug. You can find the modified version at post 12
You can also find all the parameters at
Code:
/sys/module/fast_hotplug/parameters/
and edit them with adb command
Code:
adb shell "echo [COLOR="Navy"]<value>[/COLOR] > /sys/module/fast_hotplug/parameters/[COLOR="Navy"]<variable_name>[/COLOR]"
You can configure the following parameters :
fast_hotplug_enabled : 0 for disabled, 1 for enabled
boost_duration : Duration of boost in ms when screen is touched
threshold_to_boost : Instead of automatically pluging in cores on touch, fast hotplug checks that the load is above this threshold. This avoid cores coming online when reading file or website.
max_cpu_on : Maximum number of online cpu when screen is on
min_cpu_on : Minimum number of online cpu when screen is on
idle_threshold : Threshold under which fast_hotplug will remain almost idle and won't perform any check. This applies when only 1 core is online
plug_in_core_X_threshold : with X between 1 and 3. This is the threshold to plug in coreX.
plug_in_core_X_delay : This is the number of fast_hotplug cycles (see refresh_rate) to skip before pluging in coreX.
plug_out_core_X_threshold : Like plug_in_core_X_threshold but to plug out.
plug_out_core_X_delay
refresh_rate : Time in ms between fast hotplugs checks
screen_off_singlecore : 1 for activated, 0 for deactivated; Allows only one core to be online when screen is off.
If you are using linux, you can easily change the configuration with this small program : https://github.com/pec0ra/fast_hotplug_controller
You will probably want to create init.d script to make your configuration stay after reboot. If enough users want it, I can create an example of script.
Bugs / stability
Due to some conflicts with qcom mpdecision, it is possible that you encounter some bugs / reboots when both are enabled.
Configuration doesn't stick after reboots
Help needed
If you are a java developer (or want to learn ) and want to help in developing an app (or editing an already existing one) to control the hotplug, please send me a pm
Please tell me your impression, your custom configuration and / or your recommendation so that I can make it better in future releases.

Good luck.
Will try as soon as I can. :good:

Welcome! :good:

Regarding this, there is already an app out there that is FOSS, licensed under the GPLv2 license, looks sexy and should be easy to modify. It's called Pimp My Z1, I think it offers pretty much everything you want.
Other than that, cool that you're developing something new, I'll give it a shot!
Edit:
You may want to disable Sony's RIC it prevents you from writing to /system. This should help you.

I can't seen to get notification breath effect,i didn't do the mpdecision step,so could this make the diference?

Is this kernel compatible with franco kernel apps?

Thank you for the link
I'll see if I can do something with this app when I have more time (I've never made any android app).
Disabling ric is a good idea I'll do this for next version.

No, mpdecision won't affect it. Have you tried it on YadliKernel ? Did it work for all the notifications ? It seems like on abricot kernel they work for most of the notifications but not for sms.

It is probably compatible (I didn't tried it) but you will probably not be able to change most of the configurations since they are not implemented in my kernel. Some configuration from my kernel (like fast hotplug) are also not implemented in the app so you can't change them from there.

i try with facebook,whatsapp,messaging and gmail
with a led tester its the same blink as stock
would i send you a dsmeg or anything?

There's no printing in the mod I think so dmesg would be useless. I'll try again with WhatsApp. Have you tried it on other kernels? Was it working ?
Edit : ok, maybe there is an error... In this case dmesg could be useful. If you have time you can send it, yes.
And I reconfirm that it works for telegram

Hey, can someone show us the notification mod?

Pimp my Z1
As @B1nny suggested, I tried editing Pimp my Z1 to add fast hotplug support. Everything seems to work and I even added some tweaks for a better support for our Z2 ( some default values were not really compatible with our device ). There are probably bugs for configurations other than fast hotplug. If I have time, I will fix them but for now, please use another app to set your frequencies / governors / voltage or live with the bugs. If you have questions about the app, you could also take a look at the official thread to see if it is already there or maybe just to give the dev a thanks.
I'll probably make a pull request to @Androguide.fr with the changes but until then you can use my own build linked to this post. If you already have the app installed, you will have to uninstall it first because signature is different.
You can see the full source and the changes on my github : https://github.com/pec0ra/Pimp_my_Z1
Special thanks to @Androguide.fr for his great app and to @B1nny for his link

@pec0ra
Good news to have a new kernel dev for our beloved Z2 !
However, I've tried to flash your kernel, the flashing process seems to work correctly but actually I stay stuck to the last doomlord advanced stock kernel. Any suggestion ?

You should try to extract the .elf from the zip and flash it via fastboot
Code:
fastboot flash boot <name>.elf
Anyone else experiencing the same issue ? Maybe I did something wrong in my zip.

I think you mean the .img file instead of .elf.
Other than that, the kernel works fine for me. I did manually flash it via fastboot. (because I prefer to flash it via fastboot)
I took a quick look at your updater-script and compared it to Doomlord's updater-script and this is what I found:
Your script tries to write the kernel to this partition:
Code:
/dev/block/platform/msm_sdcc.1/by-name/Kernel
While Doomlord's script writes the kernel to this partition:
Code:
/dev/block/platform/msm_sdcc.1/by-name/boot
Maybe that's the culprit?

Yes, I meant .img. It seems like it'll take some time to get used to this new device. The kernel destination you pointed out is probably the issue, yes. And that's probably the notification problem too. Seems like the kernel never got flashed so it's logical that notification mod doesn't work...
I'll change this tomorrow morning
Maybe someone can test it until then.

Yes, this was indeed the issue, I've just succesfully flashed your kernel changing "Kernel" to "boot" in the script.

That's due to Sony's RIC being enabled by default. If you look at my previous post where I mention it there is a command you can run in ADB to temporarily disable it, not ideal but it will help you rename the file.

Updated installation procedure !

It is possible a video tutorial? How i can hide the tasker notification?
I am unzip the docplug, put docplug in system/data/local with chmod 755 in folder and 644 in files, and put docplug in sd card without change permisions and restore the profile with tasker this procedure is correct?

so sdcard/tasker/...

when i go to the sdcard internal through root manager, I don't have a tasker folder. I install tasker app, and can open the app, but don't see the folder in root explorer. I'm going to try and uninstall tasker and reinstall.
I reinstalled tasker, but still no tasker folder.

[MAX KERNEL][W150][NWS2.170620.003][ROOTED]

Hi Guys, just wanted to share this little modified stock kernel i made:
* Overclock to max frequency (1100mhz)
* Activated all 4 cores
* Switched from userspace to ondamned governor for cpu
* Switched to msm-tz governor for graphics and enabled 450mhz frequency
* Pre-rooted with magisk (just install magisk apk, make sure font size is set to small in display settings to use magisk app)
Might add msm-hotplug next build but we'll see
Let me know how it works for you all, for me it made performance on wear-os 2.1 finally usable

The watch just feels waaaaaay more responsive in my view - I was looking to replace mine as it was so sluggish, but MAX KERNEL has really pepped up the performance... great work @sooti, thank you!
Anyone looking to flash this just do:
adb devices (to check you can see your watch)
List of devices attached
5xxKxKxx4xx53 device
adb reboot bootloader
fastboot flash boot boot_urbane.img
You should see something like
target reported max download size of 268435456 bytes
sending 'boot' (15334 KB)...
OKAY [ 0.594s]
writing 'boot'...
OKAY [ 1.317s]
finished. total time: 1.911s
then
fastboot reboot
Hold your breath and it should boot back into Android Wear.....

After installing, it works well. But the MagiskManager doesn't work.

Thanks very much for your work!
I'd like to try the ROM too. But I can't download it. Does anybody help me?

Just flashed this on my 4 day old urbane. I already looked the watch but I hope this makes it better

This kernel is modified better than the original. Works on all 4 cores and drain less battery. Cores start to work @ 300 for standby 384, 600, 787, 998, 1094, 1190.
Best thing is to install kernel auditor and busybox to set cores and frequency for long battery life.:good:
The best result is set @ 787 freq x 4 for battery life without harming the performance.

any updates sooti? Love your work!

J610+ custom UNDERCLOCK/OVERCLOCK kernel

I basically built this kernel a few weeks ago after @kapmino269 reported on the J4plus that cpu tends to lock at 1094mhz irrespective of load causing lag.
I also confirmed this on the J6 plus. Maybe because of thermal throttling.
Part of this seems to be caused by the rom itself as it does not support a performance mode and only a balanced mode which seems to target the middle of the frequency range and partly the Interactive governor.
Also the stock kernel has a minimum cpu frequency of 960mhz and a max of 1401mhz.
Not good for either battery or performance.
I have been testing the kernel for a few weeks and added and tweaked a new governor called INTELLIACTIVE.
This governor seems to be a good balance of battery/performance.
The governor seems to ramp up/down faster as needed both increasing performance and at the same time saving battery and lowering temps. Temps now in the 30's instead of the 40's when idling.
Touch boosts to max frequency.
The kernel now supports a min frequency of 400mhz and max of 1497mhz with no stability or overheating issues on my device.
Battery seems to have improved as does performance. However even though this kernel does try to mitigate some of the performance issues caused by the stock rom, at certain times the performance will still be at the mercy of the system.
It's here for testing by others, is based on the U1 firmware/kernel, but may work on other firmware.
You will need a kernel app such as EX kernel manager or Kernel Aduitor to modify the parameters.
I suggest setting min to 400mhz for max battery savings and 1497mhz for max performance using the INTELLIACTIVE governor.
The kernel is also root ready (will need patching with Magisk), dmverity disabled, permissive mode enabled, but not enforced, should support OTG.
As ever responsibility is with the user, I take no responsibility if your device goes into nuclear meltdown.
NOTE: At the moment all custom kernels break lockscreen functionality, so ensure no lockscreen is set.

Have you seen the response here, not sure it's worth bothering

I tried flashing to boot and to system. Bootlooping. What am I doing wrong? Do I have to convert the file?

Which firmware build does your device have? Is your device RMM patched?

yes, its RMM patched. J610G. Its rooted and works fine as per your TWRP thread. Just not getting this new kernel to work.

Which firmware build number is it running?

Yes you are correct. Sorry for the wait.
My build number is J610GUBS3BSH3.

Bro can you please add more overclock frequency for cpu and also add overclock gpu frequency custom kernel for Samsung galaxy j6+ model number SM-J610F android version 8.1.0....
bro Check this custom kernel for j6 it has more overclocked cpu and gpu but its for j6 not j6 plus(j610F). here is the link
https://forum.xda-developers.com/galaxy-j/development/kernel-phoenix-kernel-v3-5-galaxy-j6-t3901087
my device is samsung galaxy j6+ model number SM-j610F android versio 8.1.0

here bro

more oc cpu make lag .... . (bad idea dude )
j6 plus isn't like j6

idk about oreo ... if u can use disable limit .
but if u face lag give me result of :
su
cat /sys/power/cpufreq_max_limit
and
su
dmesg |grep freq

limit is there .....
use disable limit .... , it will remove lag (tested on pie)..
flash this by twrp . https://androidfilehost.com/?fid=4349826312261702503
u should have magisk before .
Test games and tell me , I use one ui pie j4+ ,pubg and call of duty is very fast .
also for j6+ stay in oreo ..... pie won't be good as no fix for fingerprint after root until now .

i flashed the script bro and run the commands again and below are the screen shots...can u pls tell if its ok or something wrong ??

kapmino269 said:
no , limit logs will appear but limit won't work .
all is ok , limit was removed , u can test cpu load
https://play.google.com/store/apps/details?id=skynet.cputhrottlingtest
... u will see that frequency won't stay on 1096 ... it will go to max .
if u tested games ???
u should see the difference .

not much difference in pubg mobile

kapmino269 said:
for me there is big difference .
Anyway I hope that help u .
notice oc gpu is ok ... but more than 650 .. , it work but phone will reboot suddenly during playing games .
also oc cpu ....is bad idea .
I mean that OC can't increase performance with all phone .
Click to expand...

ok bro.....thanks for the help.....But can i change the cpu thermal throttling limit to some higher value...so that cpu can remain on highest frequency most of the time while playing games....
Also can u give some gpu tweaks or script which can increase rendering performance...i can play in less quality but more performance

Bro i flashed this custom overclocked kernel but my device is bootlooping ?? its not working in my j610F ?? any solution pls...or any kernel for me ??

help pls

kapmino269 said:
max frequency won't be good .... more frequency == more heat = thermometer detect = force reboot to save soc .
but if u need this u can use performance governor .
for gpu ... no need to scripts .
For best game performance :
- I disabled most of apps which make lag .
- game optimize apps do the opposite with our devices(make more load ) so it is better to disable it also .
- close all apps in recent apps .
- enable don't disturb mode with hide notifications .
- play the game .

Can you give detailed information about the installation? When installing from TWRP, it asks where I want to install it. I did all the options but none of them happened.

[KERNEL][Android 11]Phoenix Kernel for Galaxy A71

Code:
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this Recovery
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
Welcome to Phoenix Kernel for A71. This kernel aims to be up-to-date with the latest 4.14 Kernel patches and to slightly improve the performance of your phone. Keep in mind that I don't own an A71 myself, so the amount of features I can add is limited. I try my best to do something good without the device.
Features:
- Removed Samsung's useless security features (considered as bloat when you root your phone)
- Removed some kernel debugging which is useless for a performance oriented kernel
- Upstreamed to version 4.14.231 (originally from 4.14.190)
- Enabled Pressure Stall Information instead of Low Memory Killer. This is a requirement of Android 11 and should improve RAM utilization (more about it here)
- Built using O3 optimizations and QCOM Clang 10.0.9 (Stock kernel uses O2 and 10.0.7)
- KCAL Color Control support (accessible via Kernel Adiutor, SmartPack etc.)
-Removed VLA Usage (here is what it means)
Prerequisites:
Your phone already is rooted, and you have installed TWRP
You are on Android 11
How to install:
Download the boot.img to your phone
Reboot to TWRP
Go to Install > Install Image > Navigate to your downloaded boot.img > Boot > Swipe to install
Flash Magisk zip and reboot

I forgot to mention. Yes you will get an "unknown error with your device" at boot. I still can't figure out how to fix it, but just know that there is nothing wrong with your phone

If you are using Phoenix kernel this is normal, but don't worry.
EDIT: now I see that I replied to the kernel creator hahaha

Thank you bro
You are wonderful.

Can you please give the overclockable version of the kernel ASAP
Let me Overclock my GPU to 810MHz and CPU to at least, 2.3GHz.
This is tested as safe, since the Snapdragon 732G have those clocks and it is the same as the snapdragon 730G that the A71 uses.

The stock GPU frequency is 500 Mhz, how can be "safe" to overclock more than 60% ???.
And the 730G has a GPU frequency of 575 Mhz...

As far as I understand this phone has the normal 730 not the 730g am I correct?

Tried this over Ncx 3.1.2 and my phone got into bootloop. Then I reinstalled the rom, but now I can't connect to my Samsung account.
Is there a way to uninstall this kernel and go back to stock or solve the samsung account without factory data?

Yes flash boot.img from ncx rom via twrp

This kernel has some problem and my phone suffered from death today on May 25, 2021.
