Hello everyone...This is my first step towards developement...I created Paradox kernel for learning and after adding many features, its time to release it to community...Paradox kernel is based on latest Lineage 14.1 sources and supports LineageOs 14.1 and all other lineage based Aosp (7.x.x) roms...My moto is to make a stable and balanced kernel having better performance as well as good battery life with usefull features

Once again, Paradox kernel is for NOUGHT ONLY (LINEAGE 14.1 and AOSP 7.X).

Features

* Based on latest lineage 14.1 sources
* Compiled using Linaro 5.4.1 toolchain
* Added cpu governores
-Impulse
-Smartmax
-lionheart
-ondemandplus
-wheatly
* Added i/o schedulors
-Sio
-Tripndroid
-zen
*Wake gestures (DT2W,S2W,Pocket Mode)
* Faux sound 3.4
* Franco Fsync control (enabled by defualt)
* KCAL colour control
* Powersuspend and LCD Notifier
* Power efficient workqueues
* Optimised crypto routines
* Push readahead to 512kB
* Optimized square root algorithm
* Lz4 compression
* Many Zram tweaks
* Disable crc check for faster performance (upto 30% increase in i/o operations)
* Blocked some wakelocks for extra battery life
* Added many tcp controllers
default : westwood

Many more features to be added...so stay tuned

Installation Instructions

Note:- If you are coming from other kernel, flash your rom before installing it(dirty flash will work too) to avoid any conflicts.
Also if you are updating to latest release of paradox kernel,you must flash your rom before flashing latest paradox kernel.

FAQ section

FAQs

[Q] This kernel works in stock rom?
NO, this kernel is based on lineage sources and works on Lineage 14.1 and all other AOSP 7.x.x roms.

[Q] Got errors during flashing/after flashing this kernel...what to do now?
Well if you are coming from any other kernel you must dirty flash your rom once to avoid any conflicts.After dirty flashing your rom flash this kernel and you won't face any problems.Also use twrp latest version (recommended)

[Q] I am having some random reboots/bugs...what to do?
Just report it with last_kmsg which is located in /proc/last_kmsg or in case of any bugs report it with logcat and proper information about how you encountered it.I will do my best to resolve it asap.

[Q] how to tweak this kernel for advanced features (like dt2w on/off,s2w on/off or changing cpu governor or i/o sechdulors) ?
Use kernel adiutor app for playing with the kernel and change the settings according to your own taste.

[Q]How to ask for any features ?
You can ask in this thread...if I find feature useful and logical then it'll be added...I would appreciate if you link me with commit. It's really hard to dig in the sources and find the exact commit.

[DarkElf]

No i have not added it yet...but i am planning to add it soon...many more features are going to be added

Luis actually its LiveDisplay conflicting with KCal...turn off live display from settings>> Display >> LiveDisplay ...after that display willbe normal. Thanks for trying my kernel by the way...

Ok i Will try it but i like use live display, another solution? And s2w is not working

Edit :- Ok guyss...i figured out the real issue...it was a tiny mistake by me and that's why when kcal colour was caliberated it automatically turned back...All is well now nd i will be updating it in an hour...this time the changelogs is gonna be huge.
S2W is working without any issues...its just disabled by default...if you want to use it then enable it first by kernel adiutor app.
