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.

Stock 32.2.A.0.253, sorry for forgetting that.

Seems pretty nice , no lags , maybe slightly smoother ?
Battery -1% during night ( 7hours)
I had a small problem with seeder app (entropy generator) keeps asking for Root and never can turn it on, I'd same problem with stock .253 kernel but Androplus V36 don't have this problem , using latest supersu 2.76

I don't recommend you to use Seeder or apps/tweaks like this (e.g CrossBreeder), your entropy will be forced to keep a highest value as possible, yah maybe there's a little smoother in UI but some tasks may be done slower (I got worse time loading of Asphalt 8 due to this). Btw, frandom is good enough to you don't need those high entropy value

Does it work on MWA and X ROM?

NOTE 3: This kernel has been hard testing on E6683, it should work on other DSDS variant (E6633), single devices got sd card not detected and it's out of reach for me atm
Click to expand...
Click to collapse
As for SDCard detection: It depends on the appended DTB used. Appended DTB is specified in the defconfig. Basically the dtb itself is the only difference between Z5 DSDS and Z5 ROW. Appending both to the same kernel _should_ work in theory (This approach was tested on the AOSP 1.2.2 Kernel), however this doesnt work on the Z5 Devices, as both DSDS and ROW share the same msm-id in the defconfig, that way the Bootloader itself can't determine which is the correct dtb, and uses the one which is appended first. This means you need seperate Kernel images for ROW and DSDS.
Took me a while to figure out for OM5Z, though I'd share it so you can save up that research time

Can any developers make an AndroPlus V36 for E6683/33 (with full SD CARD support)?

Is recovery include in kernal

Use kernel manager apps (e.g Kernel Adiutor) instead to adjust it, I kept it due to boosting the bootup time.

The kernel seems not working on custom ROM, like X ROM and MWA. Everytime I flash your kernel, it can boot normally but the SystemUi always get force closed. However, it seems work quite good on my friend's Z5 E6633 running stock firmware.
Thanks for your work.

Hello, thanks for the contribution. Have you got any plan for adding z5c support?

[KERNEL] ESAL v2 - Marshmallow

Hey, it's been a while since my last (and failed) release, so let's see if you can help me on this one.
As you might have guessed, I have compiled our latest kernel, and this is my own version!
Right now, people have reported battery life improvements, I'd love to hear what you think!
Changelog
Code:
V2.0
* Enabled some CPU governors.
V2.1
* Updated KSM with uKSM.
* Added Thunderplug hotplugging driver.
* Added PMC and Smartmax CPU governors.
* Added Init.d support. (Make sure the file has the proper permissions)
V2.2
* Updated GPU drivers to be compatible with EMUI 4.1.
* Added Intelliplug hotplugging driver.
* Improved GPU performance.
Downloads
V2.2 (New): https://github.com/XePeleato/ALE-L21_ESAL/releases/tag/v2.2
Instructions
Download the .zip
Flash from recovery
Done!
You can get the source here: https://github.com/XePeleato/ALE-L21_ESAL/tree/v2?files=1 (v2 branch)
Guide
I am going to try to help you to decide what settings you should apply
First of all, I recommend to install Kernel Adiutor.
If you prefer battery life:
Start Kernel Adiutor:
Go to CPU in the drop-down menu and set as governors PMC or Smartmax​Then go to CPU hotplug and don't enable many cores, since more online cores means more power used. You can also set the Endurance level to Quad-core​
If you prefer performance:
Start Kernel Adiutor:
Go to CPU in the drop-down menu and set as governors performance (will set the CPUs to their max frequency)/ondemand/interactive​Then go to CPU hotplug and make sure to lower the load threshold, having a low load threshold will make your phone use more cores (if you experience lag while playing, maybe it's set too low, so use a wise value, do your testing.)​
To conclude, I just mentioned where the settings are and some example values, if you love to play games you won't use the same settings as someone that just likes to read emails and use Google Chrome, find the settings you are comfortable with, and don't forget to set Apply on boot!
Now some screenshots of AnTuTu and 3DMark with Performance governor and Esalv2.1:
http://imgur.com/a/iRDpD
As you can see, even 3DMark detects that my score is higher than the average, try to beat that with stock kernel!
I hope you enjoy it, and please, I'd love to hear your suggestions!

just a quick question if you dont mind : any way to flash it via twrp ? so in case that something goes wrong i can easily restore the old one with a backup .

I'll upload a flashable zip, but it shouldn't be a problem, if you take a backup of your Boot partition and restore it, it will overwrite the kernel.

thanks! i will try it and see how it goes.

Also the governors do work , I don't know if all do but theres a noticeable performance change when chaging it. Over/Undercloking still doesnt work , but its not the kernels problem. The power genie of emui controls it.

Thanks I compiled the "v1" branche....

Wi-Fi, Bluetooth, NFC works.
I will test mobile data, GPS tomorrow.
"Bug": SIM unlock takes a lot more time than stock kernel.
Great work! May I ask what features are you going to add into? OTG maybe?
Anyway: Great! Keep it up!
EDIT:
How can I change governor? I'm looking for extra governos (PMC, Smartmax) in Kernel Auditor but I can't find them

Hi, can you find ondemand, interactive, powersave...? OTG is enabled, the problem is at the rom.

Hi,
Yes, I can.
Thank you for the heads up about OTG, I didn't know that

I'll upload a flashable zip, but it shouldn't be a problem, if you take a backup of your Boot partition and restore it, it will overwrite the kernel.

Working fine for me. The Unlocking the SIM takes about 40 seconds. Governor's work. Thanks man, keep up the good work.

Screenshot of kernel booted

First impressions are it's really smooth and seems to have great battery life compared to the last kernel I was using so I think this is a WIN. I been pretty busy lately so I haven't been doing much to my phone but I'm glad I can hop on XDA for a few mins and flash something to make my phone perform better without me having to use scripts to improve anything. Good job

Great, thanks for sharing.
Compared to androplus kernel, what are the pro/cons?

Not booting my phone with this kernel. I am using eXzistenZ v8 custom rom. Androplus Kernel v29 is OK.

i can also confirm not working on existenz rom v8.0 but it will work on stock one probably.

I can confirm it working on stock rooted ROM
There might be a slight lag but a fix by turning stamina mode on then off will fix it
Standby time will be reported in a few days

It seems like whatever settings we had before we flash kernel is what it uses as config. So in my findings it keeps the scheduler values and Governor values the same. So I had to edit these values as it did cause a issue. I was using duality kernel prior.

I agree, I suffered noticable lags when I enabled Deez nuts 8 SE and with the kernel at the same time

Holy smokes, works very well on my XZ. I also used your kernel, which is also very fast, thanks!!

Did you will make kernel for Oreo ?

I'm too lazy to upload it and I removed some core features e.g. CPUQuiet, frandom,... because they doesn't work well on stock.

[Kernel] SMF-KERNEL - RR/AICP/LOS/AOSP - 8.1

Hello!
I want to introduce my first custom kernel for the Essential PH-1. This is based of several sources, I cherry-picked commits to make improvements to the stock LOS kernel. I'm not a developer, but i really like to port stuff over .
Kernel is suitable for AOSP based ROMS such as RR/AICP/CARBON/LOS etc... If you want to request for specific features, let me know and i'll do my best to bring them over.
Special Features:
Updated to lastest LOS Stock Kernel
Added a few governors like: cultivation / impulse
added a few IO Schedulers: Maple
Kcal Color Control driver
USB Fast Charge - pending will be added in R2
SafetyNet Patch (Bypass bootloader unlocked check)
Dynamic Fsync control
a little Overclock - will be added in R2
Motorola Quickwake - Will be added in R2
and manny other small fixes (you can check the commits in the sources)

Disclaimer: I am not responsible if you use this and brick your device or if your device blows up, implodes, flames start shooting from it or it kills your neighbor's dog. Flash at your own risk. I am not responsible.... It was the other guy... I swear....
Latest Release: SMF-Kernel R2
Known issues:
05.17.2018 - CPU Freq don't always stick, known issue caused by other drivers. Phone will eventually set your frequencies, dont' panic.
Installation:
Obviouly you have a Unlocked Bootloader since you're running a custom rom (make sure to never lock your bootloader in this state)
Boot into Bootloader (adb reboot Bootloader)
If you want to root flash the "Magisk" version of the kernel, it's been prerooted with the latest Magisk Beta available.
Code:
fastboot flash boot SMF-Kernel-R1-Magisk.img
reboot
If you want to manually root, first flash twrp, then from twrp flash the 'non magisk' version and after that flash the magisk zip.

Looks awesome! I'll give it a try soon!
(For anyone wondering about overclocking the CPU, he committed some changes to the github that would apply this and it should appear in the next revision of the kernel.)

Just installed and so far it's buttery smooth.

I'm glad is running fine for you!

Good stuff, thanks for this! Could you tell me a little more about cultivation? I can't seem to find much information online about it
Also a request, if possible vibration level control would be super appreciated

I found Cultivation to be really great in terms of perfornance. It's a little bit agressive with the CPU so you get buttery smooth experience with Screen On but it may cost a few % on battery at the end of the day. The good thing is that it has specific tunables and you can set a low cpu freq for when the screen is off.
Specific details from its developer:
-based off of caf 4.4 commits
-uses per-pcu timers
-use state_notifier for screen off timer
option to set different timer rate when screen off
-improrted fastlane with threshold from blu_active
In regards of vibration control. It should be there. I'm using EX Kernel Manager and i can see the vibration option under "Miscellaneous"

Thanks for this. It's running amazing so far. Performance has been great and I'll see how battery life is, but so far it's great.
I can't wait for further updates. I really wanna see what Moto quickwake is haha

Thanks for the info on cultivation, I don't mind trading some battery life for butter so I'm using it now
For the vibration control, it doesn't actually work/stick. I've tried kernel auditor and EX Kernel Manager. To be fair, so far it has only worked on LOS and I think invisiblek may have rewritten the stock controller or something so no worries if it isn't a high priority haha

I'll take a look at the latest commits but I've used the latest los kernel base so I'm not sure why is not sticking maybe it needs rom support too (not sure honestly) hahaha
I've been testing R2 since yesterday. Will update after y he weekend!

Just out of curiosity, was anything involving the camera done to this kernel? I am now able to record videos without the bug, on any of the affected ROMs, with this kernel.

Nothing related to camera. Are you sure it works with no issues?
What roms have you tested?

So far, AICP and LOS, both with Essential camera app and GCAM port, HD and 4K, 30 and 60 fps where applicable. Issues presented before flashing very consistently, and so far I have been unable to replicate after flashing this kernel.

Sp you were right. Honestly don't know what happened but I installed the latest RR (clean install) put R2 on top of it and bam recording works as you mentioned lol..
I guess it was a lucky strike!

after flashing the kernel with magisk, stuck on "AICP is starting"
is this normal?
update: the phone works but no magisk (pre root) after flashing the kernel.....

Hey!
Have you booted once and setup everything before flashing the prerooted image?
I've had that error but having all set and then flashing the image will get me rooted. Try to see if you can find magisk manager in the apps list from the settings if you do, reboot and there will be magisk

Double post... Sorry

Thank you for the reply.
the phone was running AICP and I wanted root so I flash the kernel. I can't find the magisk manager or in the settings about magisk. I guess you have to clean install from the beginning to get the root. Thank you for the Kernel

Shouldn't. If you flashed the prerooted magisk image try downloading the magisk manager app manually from xda and see if magisk works
