Features:
Pie base: CAF & Prima Tag by LA.UM.7.6.r1-04500-89xx.0
Oreo base: CAF & Prima Tag by LA.UM.6.6.r1-11000-89xx.0
Legacy base: not updated pure sources from MiCode github
(prima tag LA.UM.7.6.r1-05500-89xx / LA.UM.6.6.r1-11300-89xx.0)
• KCAL color control
• Vibration intensity control
• Sound gain control
• Audio codec quality improved
• exFAT Support
• NTFS support
• F2FS support
• SquahFS support
• CIFS/SMB support
• Added CPU Hotplug (default disabled)
• Set lz4 for better zram work
• Boeffla wakelock blocker
• Added defaults rules for Boeffla wakelock blocker
• Disable vendor verify and set no verity
• CRC32: disable by default & enable toogle (average 30% I/O performance profit)
• Few patches from Franco kernel (disabled a lot of debugging stuff)
• Fsync: on/off support
• Battery deep optimisation: undervolting & additional tweaks
• Added Adreno Real Idler (supported turning it on/off)
• Improved interactive governor (patch from Franco kernel)
• Improved CPU boost, default is disabled (patch from Franco kernel)
• Improved conservative governor (patch from Franco kernel)
• I/O schedulers: noop, deadline, bfq, cfq (default), sio, fiops, maple, tripndroid, zen, anxiety, sioplus, fifo, v(r)
• Added CPU governors: darkness, zzmoove, relax, impulse, electron, nonconservative, lionheart, clarity, blu_active, yankactive, intelliactive, conservativex, ondemandx, interactivex, bioshock, darknessv5, alucard, smartmax_eps, pegasusq, lionfish, hyper, despair, barry_allen, xperience, alessa, chill, ondemandplus, ironactive, culvitation, tripndroid

• Fix for goodix-fp gestures on stock (thanks to @artyom5613 & @Broomber)
• Also in the v4 installer included fix fpc-fp gestures for the customs rom
now gestures for both fingerprints is are:
* swipe2right - paste text
* others like in rom's setting
(if you not like this - change it in the /system/usr/keylayout/uinput-*.kl)
• Memory & battery life optimization due config settings for kernel
• Added a block to wakelock from wifi
• I/O optimization
• Hide unlocked bootloader state (for apps like bank clients etc)
• Patches from Franco "mido" kernel for battery life improvement
• Added gpu Adreno simple algorithm (beast!!)
• Found a reason for which the CPU could for a long time not to raise the frequency to the maximum, it's all in the file /vendor/etc/thermal-engine.conf
See samples how to improve situation
• Compiled with GCC 9.1.0, which gave an increase in performance and speed of the kernel
• Reworked undervolting, battery lives even longer
• Added voltage control
• Maximum CPU frequency is now 2.4GHz
• EUOC version has a maximum GPU frequency of 750MHz
• added support for display status for CPU Hotplug & some schedulers
• all schedulers that have display status support:
alucard, chill, clarity, cultivation, darkness, electron, impulse, intelliactive, ironactive, nightmare, relaxed, anxiety-iosched and maple-iosched
• added drivers for few USB-Ethernet adapters
• added nightmare and dancedance CPU governors
• updated version with 2.2GHz overclocking
• removed the patch for hiding the bootloader state (there are more problems than good with it)
• new settings for a smooth interface in installer (applied for GSI only)
- DT2W fix for fts_ts [default disabled] (thanks @33bca) * tested on customs and GSIs. for latest maybe need to enable "Handwave gesture" in "Phh Treble Settings" > "Doze features" * #TODO
- Installer include Magisk preserve #TODO

<< download Pie v5.5 || download Pie v4.4 >>
<< download Oreo v5.5 || download Oreo v4.4 >>

undervolted (U) lower voltage for decrease overheat. also incredible battery saving
overclocked (OC) CPU max frequency is 2.4GHz, GPU max frequency is 725MHz
extra-overclocked (E) GPU max frequency is 750MHz (if you will face with graphical glitches - don't use it!)

Installations:
Backup boot.img, /system/lib/modules, /system/usr/keylayout and /vendor/lib/modules folders, /vendor/bin/init.qcom.post_boot.sh file if you want to go back
Flash Zip file with any TWRP recovery, wipe Dalvik cache, reboot and enjoy ^_^
Notice: if you have Magisk with modules installed maybe you'll get bootloop.
If you have Magisk don't need reinstall it after kernel because installer will save Magisk #TODO
Right way: if you have Magisk and modules - deinstall all. Then flash stock boot.img, then custom kernel, then other stuff like TWRP and Magisk.
Enough just dirty flashing kernel and then Magisk if you need it. All yours Magisk modules will preserved.

Issues:
- DT2W not work for fts_ts touchscreen
- tell me if find

I will not help users if they are:

- using Magisk and moreover they installed modules;
- made any kernel settings (selected exotic governors, turned on hotplug and etc.);
- using option "Disable HW overlays";
- not sure that the same problems were not on the standard kernel
- not follow installation guide

All OC versions is always have CPU 2.2GHz

if not for you, then this is maybe if:
- you SoC/voltageregulator/phone doesn't support overclocking
- your device overheated due high outside temp or high load
- you system set restrictions to overclocking

Now im using CAF kernel with stock rom i want to flash butterfly what should i do delete CAF then install it??and for magisk delete all modul ?

yes, thats right

you may try dirty install but this is not a guarantee what system boot due to magisk specific

best way is remove all modules from magisk, remove magisk via flashing stock kernel and then boot to twrp and install butterfly

Ok i will try it thx bro

[Zewyni]

May I ask if this kernel could be modified so we can overclock? How exactly do we need to go about and do the modifications to the PLL tables? It'd be great if you could help out and make a tutorial or something.

no, this build haven't overclock feature

Improved interactive CPU governor (patch from Franco kernel)
Improved CPU boost and enable it (patch from Franco kernel)
Reworked conservative and nonconservative CPU governors
Reworked guardian, balanced and msm-adreno-plus GPU governors
Kernel installer now also support custom ROMs

Also have some changes in Power profiles

The touch sensetivity is somehow better with this kernel but I really miss dt2w... I'll be testing it for the week, hope you can fix dt2w! Thanks for your work on our device!

dt2w not supporting due missing stuff in official Xiaomi kernel sources

[BJumperBR]

I can confirm that touch sensitivity is better on this Kernel. Gcam also runs smoother!

ExFAT support doesn't seem to be working though. I've tried to read an SD Card ExFAT formatted and it didn't work (corrupt error message).

How to switch from one profile to another? I have kernel adiutor installed but there is no profile I the kernel section to select. Thanks to everyone answer and to the Dev for his work. Sorry for my English

you may create various profiles in Kernel Aduitor

Tools > Profile


and which rom you using?

I'm using stock ROM Pie 10.0.4 update version.

 

[eremitein]

Kernel updates (see topic)

Changelog v2.99:
Added new builds:
- Oreo base CAF & Prima Tag by LA.UM.6.6.r1-11000-89xx.0
- Legacy base (not updated pure sources from MiCode github)
- Installer totally fixed for support wifi on custom roms

Oreo base is only for oreo vendors (9.6.x.0 versions)!!!
Why i built this and legacy variants?)
For compatibility. Because some people still using oreo stock or 8.1 vendor with GSI

for clean testing exFAT you need should be sure what ROM have support this FS

if with other kernel on your rom exfat work then, yeahh, something wrong with my kernel exfat


thanks for feedback)

I'm on Stock ROM 10.0.4.0.

So, no exDAT support, right?

 

[Henki98]

I am undecided whether to stay in oreo with this kernel or pie always switch to this kernel.
It is wrong to ask, instead of trying, but I don't have much time to test
No one with any feedback on the battery and stability?
(Noob question, what is it the difference of legacy kernel? )
