I am not responsible for bricked devices, dead SD cards, explosions, nuclear wars, alarm applications getting failed, Please read the first 3 posts carefully before deciding to flash this kernel.

This is the first custom kernel for kenzo, this kernel will focus on quality over quantity, I will add only those features which don't cause instability and really improve performance or battery life of our device.

Thanks to all the kernel developers for many ideas, references and features, special thanks to TheStrix and Balika011 for CM bringup, special thanks to Xiaomi for providing kernel source code of this great device.


Included Kernel Features-

Cpu Improvements -
  • Balanced, Battery and Gaming modes available for interactive governor.
  • Mild undervolt for our cpu, reduces heat, helps battery backup.
  • All basic governors and impulse governor available, default is interactive.
  • Option to enable/disable smart hotplugging, select while installing.
  • Toggles for wakeup boost, hotplug boost, touch boost.
IO Improvements -
  • CRC32 hw accelarated module
  • Some optimizations for performance.
  • Added fiops, bfq, zen, maple io schedulers.
  • Disabled IO crc check for more performance.
  • NTFS, exFAT, F2FS, EXT filesystems support.
Gpu/Display Improvements -
  • Fixed wrong gpu frequency reflected in sysfs
  • Optional enhanced color profile, choose while flashing
  • Adreno idler and adreno boost are available, off by default
  • Savoca's kcal color control, full control over colors
  • Wake gestures, dt2w, s2s and s2w for all panels
Charging/Battery Improvements -
  • Option to select max charging rate limit when installing.
  • Option to select either 2000mA or 2400mA rate.
  • Optimized power consumption for cpu and gpu.
  • Mild undervolting for both cpu and gpu, stable.
  • Optimizations for better power management.
Other Improvements -
  • Sound control for speaker, earphones, mic etc.
  • Option to select selinux mode while installing.
  • Compiled with aosp 4.9.4 aarch64 toolchain.
  • Faux dynamic fsync available, on by default.
  • Custom vibration intensity control available.
Confirmed working or not working on -
  • Works on all lineage and aosp based marshmallow roms
  • Works on all lineage and aosp based nougat roms
  • Works on all MIUI 8+ marshmallow roms
Flashing Instructions -
  • Prefer flashing over your rom's stock kernel for best results
  • Read post #2 for some frequently asked questions
  • Download correct version of Radon kernel
  • Make backup of system, boot in twrp
  • Now, wipe dalvik cache and cache
  • Flash the kernel zip and reboot
In case the kernel doesn't boot, you can restore your system and boot partition from twrp and you will not lose any data.

Frequently Asked Questions -
Q ) I like this kernel, can I be a part and contribute to this project ?
Quote:

It takes many hours to maintain this kernel, If you are a user then donations are much appreciated. If you want to contribute to development then you can create your pull requests on my github or pm me with your patch, proper authorship will be given.

Q ) I flashed this kernel, what next ? How and where do I configure kernel related settings ?
Quote:

Recommended apps are "Kernel Adiutor" or "EX kernel manager" both of them are available on google play store, install any one of them and refer post #3 for my recommended settings.

Q ) I am on nougat and my camera and flash are buggy on this kernel ?
Quote:

This is a known bug that you will find on all nougat roms, this is not kernel specific, flashing kernel will not fix your occasional camera crashes, you have to live with it until devs find a solution or xiaomi releases nougat for kenzo. If you want perfect camera/flash then you should try marshmallow roms.

Q ) Read mode in miui is not working after flashing this kernel ?
Quote:

Thats true, xiaomi hasn't provided the opensource code for this feature, so read mode is not going to work on custom kernels, but you can try going into kernel adiutor's display tab and tune colors manually.

Q ) My fingerprint or front camera doesn't work, what to do ?
Quote:

Xiaomi gave us old sources and started manufacturing device with newer hardware, ask xiaomi to update their kernel source, even without complete sources, most of the variants work perfectly but you can tell me if anything is broken for you.

Q ) I flashed this kernel, but I want to return to my stock kernel, how to do that ?
Quote:

If you read flashing instructions in first post, you will see that I asked you to make backup of boot and system partitions before flashing my kernel, now you can restore that backup and you will have your stock kernel back. In case you didn't take a backup, just dirty flash your rom zip without wiping data and that will restore stock kernel and modules.

Q ) How much battery backup does this kernel give ? Will it give me x hours of SOT ?
Quote:

The battery backup totally depends on your usage, like screen brightness, wifi, 3g/4g data. Changing your kernel or rom will not make battery backup double. According to my observations, our device can last upto 2 full days with light to moderate usage giving 9+ hours of screen on time with wifi only usage, If you use your device continuously then you might be able to get 10+ or even 11+ hours of screen on time. Heavy 3G, 4G, Bluetooth users shouldn't expect huge battery backup. Regarding battery consumption when display is off, I normally lose 2-3% battery for about 6-7 hours of standby, but if you you keep wifi and data off in night, then you should get only 0-1% drain per night.

Right, overclock is not useful unless you are using a low end or outdated device.

Yes so please don't add over clock lol maybe any sound changes like faux sound or Franco sound? If it's possible of course.
