Introduction
Hello everyone, this is my personal kernel for kenzo. My philosophy on kernels is pretty simple:
Follow upstream Linux always
Security and stability are paramount
Features will be added only as needed
Hopefully you enjoy
Thread Rules
I refuse to acknowledge/respond to bug reports that do not include clear steps to reproduce, a logcat, and a console ramoops (if random rebooting) or a dmesg (any other issues). Follow this guide to do this. More on bug reporting policy here.
Keep things civil, I do NOT tolerate flaming of any kind.
UV Support ( Already UV'd with the best stable values)
Updated to the latest security patch (August)
Updated to the latest Linux upstream version (3.10.107)
Several CVE fixes
Upstream patches from CAF and Linux
Touchboost force disabled
KCAL color control
Wake gestures (sweep2wake, doubletap2wake, sweep2sleep)
Franco Sound Control and Flar2 Sound Control
ZRAM support
I/O schedulers (maple, noop, deadline, row, cfq, bfq, test-iosched, sioplus, zen, fiops)
TCP Cong support (westwood, reno, bic, cubic, htcp, vegas, yeah, illinois, lp, scalable, veno, hybla, highspeed, )
Wakelock controls
F2FS support
exFAT and NTFS support
Compiled with a Linaro 6.4 TC
Makefile optimizations (courtesy of @adinkwok)

Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not an amazing kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue, following this guide. If I can't reproduce reliably though, I'm not going to fix the issue.
1.2 Q: Can you add xyz feature?
1.2 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration.
1.3 Q: How do I control the kernel?
1.3 A: I'd recommend using either @flar2's EX Kernel Manager or @Yoinx's Kernel Adiutor-Mod; both are extremely solid and have given me no issues.
1.4 Q: What ROM are you on? What are your settings?
1.4 A: Currently, I am on AICP and my settings are available here here
1.5 Q: OMFG MY BATTERY SUXXXX PLS FIX!!!
1.5 A: The kernel doesn't drain any battery, use an app like BetterBatteryStats to figure out what app is screwing with your phone.
1.6 Q: Does it boot in BlackscreenOS ?
1.6 A: I don't know. You can try.
1.8 Q: Can you add Quick Charge support ?
1.8 A: No.
1.9 Q: Bro, i have kate variant, can i use it ?
1.9 A: Of course.
2.0 Q: QC support ?
2.0 A: Don't be ridiculous.
2.2 Q: How about GCC 7 support ?
2.2 A: Currently, GCC 7 cannot be booted on kenzo.
2.3 Q: Why it shows me random max frequencies?
2.3 A: If you're using LOS Based rom is an expected behaviour, don't worry, it won't ruin your performance, is same as before.
2.4 Q: Slow charge bro please fix!
2.4 A: Bro pl0x upd8te fermware.
2.5 Q: Core 6 is offline bro!
2.5 A: Really? wew, enable it and make it default at boot.
2.6 Q: Where i can find you sur?
2.6 A: Either on Telegram(My XDA Username) or G+ sur.

sum moar kenzo kernul pls sur dev
Always happy to see more upstream kernels cropping up around the place

Thanks for this awesome kernel It is a nice thing to see a good developer works on a kernel for redmi note 3. I didnt want to use elementalx cuz of lack of upstream and now you came up with this. And the reason why i dont wanna use other kernels is they have so many patches that dont have a impact on performance in my opinion.
Ty :good:

wew, despacito it's here
Very good kernel :fingers-crossed:

6.4 de

Wow. Great to see you here Aex (oops missed l)

It's amazing
thanks for your work
I got around 2000 ma for charging so that's great and it's faster somehow on Aex rom
don't stop supporting it

Wow. Another kernel for Kenzo. Thank you so much dev. Gonna try this definitely. ?

Wow, nice work, new kernel [emoji7]
Enviado desde mi Redmi Note 3 mediante Tapatalk

Ow nice lets try this on Aosip and rr rom hehe

Thank you so much for this new kernel. Downloading it.

Wew Sur :cyclops:
Hoping for 69 min quick charge and 69hr sot :angel:

*when you want to use AICP but the update frequencies rekt your mobile data*
This is the best solution! Thanks for the new kernel..

Which rom are you using?

Yay, another kernel! Might try this and switch from EX kernel... Keep it up dev/bro!

Support IR? @GeekDragon
Im using RR, but Dominator dont support IR, so i replace the kernel with ElementalX,
Just to use MI Remote,
otherwise i always prefer Stock kernel that Comes with the ROM.

5. Notkernel has ___ bug || ___ doesn't work properly on Notkernel
> Bugs and issues are common in custom kernels. We are by no means pro's at the job and may mess things up at times. But we do let the kernel go through a bunch of testing by the members of our Testers' group, so the chances of major bugs existing in the release builds is comparitively low. However if you do end up facing bugs, please do report it through our support group or messaging me on Telegram[Yasirsiddiqui]. Even if you are not in a state to give any logs or detailed description, at least mentioning it to us briefly would help us a lot.

Wow, nice, good job, will try it out!

A520l will try tomorrow

Working Great with pixel experience ROM, I've upped the voltage on GPU and CPUs , Played COD mobile default all is good , used GLtools to get max graphics , and again all is good

Just flashed it. Already encountered a bug, hk keeps on loading. Looking forward on your developments. Good luck
And unlocking the phone through fingerprint seems slower now for some reason. Opening apps is also slower now. Btw im using Google pixel Pie Plus

Flashed it and working good so far. I think you're the first to make a custom AOSP kernel for this phone.
Magisk 20 is working for me, it just takes a few tries to boot sometimes.

Unlocking the phone takes longer because the CPU clocks down on all cores when the screen is off. Therefore it needs longer to unlock. At least this is the explanation that makes the most sense.
That apps are opening slowly sometimes is also a bug I encountered, forgot to mention it in my OP thread. This can be fixed by simply reinstalling/updating the app or doing a clean flash (install ROM, then kernel right after)

I'm laughing so hard thinking of this title as "Riiiiise and Shiiiine" Project
Good work btw

With crDroid and this kernel, I got 106k in antutu. I love the fast charging too. Such an upgrade compared to "stock" aosp.

Latecomer... flashed and rebooted first time on Magisk 20 using crDroid
Going to have a play with some features and report back if I find anything useful.
Thanks Simon

97117 for me. Going to tinker then have another go. Best score I've ever had on this device though.
Replacing the device soon though

So far so good. Been trying some settings I had on my Xperia SP about 4 years ago and they seem to be working well for a balance of performance and battery.
Simply put:
CPU governor - Interactive (max and min frequencies set at maximum and minimum accordingly)
I/O scheduler - Fiops with Internal Storage read ahead set to 1024KB
I/O scheduler - bfq with External storage read ahead set to 1024KB
No CPU hotplug (really only useful for stock Sammy kernel)
That's it
Feel free to try and report back with your own findings.
I'm finding little lag now (was getting some really big lags and micro freezes) and battery draining slower

My results was with GPU overvoltaged and no apps other than hKtweaks, magisk and antutu. So hardly real world.

With crDroid and this kernel, I got 106k in antutu. I love the fast charging too. Such an upgrade compared to "stock" aosp.

Works on MiUi flawlessly.

FKM OTA SUPPORT ADDED (everyone will recive OTA)
................................
STEPS:
1) open your FKM and fro menu please select flasher
2) now at top there is option "import a kernel configuration"
3) please click on that and add this link : https://raw.githubusercontent.com/rakeshraimca/OTA/master/fkm.json
4) save.
now FKM will popup the latest kernel available and you can even see changelogs or download or flash directly from there.

After trying every kernel out there, I can surely say this is the best Kernel for Poco X2. Thanks for the hard work OP.

Is there any way to backup current kernel and then flash this?

Click to expand...
Click to collapse
there are many ways...
TWRP
Kernel apps( kernel auditor , FKM)
Essential tools (root essential from playstore etc)

After flashing this kernel and changing couple of settings, i.e. min freq for both big/small set to 100 Mhz and CPU governor set to interactive (and apply these settings on boot), do I need to have KFM/Mtweaks apk installed or I can uninstall (or freeze them or disable) them?
Edit: Seems like this wont work if I remove/disable the app, as on boot settings enforcer itself is these apps. App is required.

Thanks for your great job
This kernels works on both miui and AOSP rom?

[B]**** Disclaimer: I'm not responsible if you destroy your device. Use at your own risk!!! ****[/B]
As the name shows, this kernel was started as a parody for some existing kernel as most of their has something from pro, plus, etc.
I started this kernel from my older days of sanders (Moto G5S Plus) device, continuing it for RMX2170 (Realme 7 Pro) device. The kernel for RMX2170 and RMX2061 is based on sagarmakhar's AEX kernel source with additional features. For now only minimal features exist, more will be added in sometime of future .
Some of the features are listed below,​• Basic linux kernel

PEOPLE REPORTING DT2W ISSUE NEEDS AN UPDATED REALMEPARTS APP COZ OF THE CHANGE IN CODE OF DT2W KERNEL SIDE.

Is some RMX2170 kernel with NetHunter support?

Double taps to wake and fast charging doesn't work (tested with CrDroid rom). But keep up the good work anyway.

The code for double tap to wake has been changed in kernel source hence the roms that has been using older dt2w code won't be compatible for dt2w. Try newer A12 roms for dt2w.

Hi, The kernel is superb and fantastic but I encountered a bug. Based on my experience, It is not supporting Superdart charging it is like limiting the current entering the phone. Hoping to fix the issue Thank you
