INTRODUCTION
I wanted to port f2fs for our device since it gives a nice performance boost. After few months of learning how to develop and program his own custom kernel here is my first personal release.
This is an open devDB xda project. Feel free to fill in bugs reports, feature(s) requests and reviews.
To those who don't know what is f2fs
F2FS (Flash-Friendly File System) is a flash file system created by Jaegeuk Kim (Hangul: 김재극) at Samsung for the Linux operating system kernel.[2]
The motive for F2FS was to build a file system that from the start takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.
Some benchmarks to point out the performance difference between EXT4 and F2FS
AndroGuide benchmarks : ext4 vs f2fs ( seemes to be using the most recent f2fs)
XDA's benchmark : ext4 vs f2fs
Phoronix's benchs ext4 vs btfrs vs f2fs
Another Phoronix's bench
Optipops features :
Kernel's features :
Kernel's features :
- Compiled with linaro 4.7.4 with optimized flags : O3, etc.
- Linux 3.4.67: synced with cyanogen 's manta kernel git, google's common branch, some parts of the kernel updated to 3.4.108, and many fixes from CAF,linaro, blabla.
- Governors : interactive, intelliactive,intellimm,conservative, ktoonservative , performance, userspace, nigtmahre(on request)(ask for some others if you prefer them over the one I provide)
- I/O schedulers : noop, cfq, deadline, bfq(tweaked for nand devices),fiops,zen,sio
- f2fs updated from upstream git(08 september 2015)
- UV and OC both for the GPU AND CPU supported
- Control for the gpu table thresholds
- touchboost driver for cpu and gpu in replacement of crappy powerHAL touch interface ( thx @franciscofranco to have adapted qcom code to ageneric one)
- arm optimized crypto algorithms.(for the ones that want to crypt their data)
- f2fs crypto support
- kernel neon support
- kernel side touch boost driver
- double tap to wake
- AnyKernel2 Solution: Allow users to install the kernel on different distribution. It also detects the filesystem of your partitions to produce a correct fstab. ( f2fs is supported on any partition BUT system )
- and many more patches(see my github!)
installation instructions :
- Wipe Data Cache System
- Flash The kernel
- If issues are met, delete the

How To Migrate one partition from ext4 to f2fs(vice-versa):INSTRUCTIONS FOR TWRP 2.8.x.y
GunnerOnASpooky said:1. Backup everything from your internal storage to your PC or what ever, if you are migrating /data partition,since the entire internal storage is going to get wiped out with format!!!!!!!!!!
2. Download the recovery from my gdrive
3. Flash the recovery from the bootloader (fastboot flash recovery XX.img)
4. Reboot into the newly flashed recovery
5. Choose wipe, advanced, then select the partition you want to change its filesystems
6. Choose the change file system option on the right
7. Select change file system again
8. Select f2fs(or ext4)
9. Repeat for all you wish to convert (I did system!/data/cache but /system partition should be working if you rom package flash extracts instead of flashing an image)
