​

Features:
Linux upstream: 3.18.140
CAF & Prima upstream: LA.UM.7.6.r1-05500-89xx.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: undervolt & 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
• Added GPU governors: guardian, balanced, msm-adreno-plus
• TCP congestion algorithms: cubic, reno, westwood (default)
• Installer include fix for Wi-Fi SELinux permission
• Kernel installer also support custom ROMs
• GCam focus fix (thanks @teftel1608 and @33bca)
• GPU: clocks table reworked (lags free, performance grew). OC max gpu freq now is 725MHz
• Fix for goodix-fp gestures on stock (thanks to @artyom5613 & @Broomber)
• Also in the v1 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
• Added WireGuard 0.0.20190601
• 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 preset in installer for a smooth interface (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

<< DragonHeart v3.3 || DragonHeart v2.2 >>

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

[Henki98]

also for oreo?

 

[marstonpear]

What are the differences between this and ButterFly kernel?

 

[BlazingBullets]

whats the difference between this and butterfly? changelog looks the same

 

[Sonthaya]

Same butterfly only upsteam

 

[syukri95]

How to change from butterfly kernel? Just dirty flash?

 

[eremitein]

also for oreo?

never. this base have only pie kernel

Same butterfly only upsteam

you right)

How to change from butterfly kernel? Just dirty flash?

yes

OC versions always run at 2.2GHz or only when under load such as playing games? If it always run at 2.2GHz, will it hurts CPU in long term?

 

[saksham_033]

@Funk Wizard I'll request you to look into it due to violation of GPL license in a kernel thread and also Improper kernel commit history.

 

[Veran125]

What is exactly the difference between this and Butterfly kernel? Furthermore, is it recommended only to flash this on a CAF-based rom? If so, can't we only flash it on the caf-based build of PE?

i wrote "have"
not "run"

all kernels for daisy is always CAF

different is in base - this base is upstreamed CAF & linux, latest butterfly based on the legacy Xiaomi sources

 

[wenna.speedy]

Tell me if it is better than butterfly.

 

[DarkFrenzy]

is wifi working in UV kernel? (DragonHeart-daisy-20190612-v1-U.zip)

I'm have many temp is down to 1689

 

[eremitein]

is wifi working in UV kernel? (DragonHeart-daisy-20190612-v1-U.zip)

why you asked?)

all builds have working wifi

but some magisk modules may brick wifi on any kernels

 

[aerzjee]

@eremitein is it possible to add voltage control interface so we can control it ourselves in ie. Kernel Adiutor ?

 

[CherryFarmer8]

Im on Piexl Experience and magisk installed with some modules installed like youtube vanced etc.
Can i just Dirty flash it or i should i follow some steps??

maybe in future...
now i don't have much free time for developing. and also my google build server is suspended (trial time is over), so i take pause for rest

the source codes of both of my kernels are available on the Github, anyone can take and use them on the basis of the GPL - learn how to build kernel, add functionality, modify and release(with saving all copy(left)rights in the code and publish it), build into the rom... you can get quick acquainted with the GPL here

please, people, please - read first and third posts and you'll find all answers:angel:
