10Should work on ALL P51xx models !!!
Source : https://github.com/psndna88/AGNI-pureSTOCK/tree/pureSTOCK-P31xx-4.2.2
NEW pureSTOCK v3.5 (4.2.2)
- removed ROW-v4, V(R), BFQ I/O schedulers (probematic and not fully compatible)
- removed mutable "Android logger" and "Kernel printk" interface (not of much use)
- removed preloadSWAP to avoid accidental SecSettings.apk deletion in /preload for users using odin flashed Stock 4.2.2 rom
- removed ExtSd2InternalSd (not supported yet)
- set interactive as default cpu governor
- set cfq as default I/O governor
- compiled using GCC 4.7.2 with cortex-a9 optimised
- kernel zip package includes all required blobs (single all-in-one package)
- Update v2.1a:
fixed all kernel related freeze bugs (special reference to TouchWiz) | proper permissions are automatically set on init.d scripts before execution (user now needs to just drop in scripts and reboot) - Update v2.1b:
added new lowest cpu scaling frequency of 180MHz (more battery save for idle times) | /cache is formatted and dalvik-cache is cleared automatically upon flashing | "AGNi_fix_app-data_permissions.zip" recovery flashable package will be put on your internal sdcard, you can flash it if by chance you have app FCs/laggy system caused by app permission issues | changed compresion of compiled kernel to LZO for faster decompression in an attempt to minimise boot times - Update v2.1b FIXED:
disabled auto format of /cache and dalvik-cache clearing on flashing | users having app freeze issues should flash once "AGNi_fix_app-data_permissions.zip" | fixed slow starting boot animation issue and boot time may be lesser than before - Update v2.2:
rebased from SAMSUNG OSRC P3100 JB Update 3 (4.2.2) sources | Implemented some Zram modifications with 4 zram devices support | Introducing AGNi Main user profiles (Extreme Battery Save / Battery Save / Normal / Gaming) & user can override settings at will | drop & forget for init.d scripts (user doesnt need to set permissions manually) | expect better performance - 29-10-2013 Update v2.3:

Supporting frandom kernel-mode RNG-entropy generator (~10x faster than default urandom) : speeding up seeder or such entropy enhancing scripts - 02-01-2014 AGAIN Reuploaded v2.8 (take it as my liking for 2.8)
tweaked "random" (the default linux kernel RNG/PRNG device) | added Frandom lagfix-helper option in boeffla tweaks (/dev/random and /dev/urandom is replaced by symlinked /dev/frandom and /dev/erandom respecively = speeds up entropy generation without seeder app or rngd service) - 03-01-2014 AGAIN Reuploaded v2.8 (take it as my liking for 2.8)
Replaced "Boeffla Tweaks" app with my modified "AGNi Control" app (TESTED ART COMPATIBLE) [ THANKS to @HM.Carbide ] - 25-01-2014 Update v2.9

WHAT IS Flash-Friendly File System (F2FS)?
================================================================================
NAND flash memory-based storage devices, such as SSD, eMMC, and SD cards, have
been equipped on a variety systems ranging from mobile to server systems. Since
they are known to have different characteristics from the conventional rotating
disks, a file system, an upper layer to the storage device, should adapt to the
changes from the sketch in the design level.
F2FS is a file system exploiting NAND flash memory-based storage devices, which
is based on Log-structured File System (LFS). The design has been focused on
addressing the fundamental issues in LFS, which are snowball effect of wandering
tree and high cleaning overhead.
Since a NAND flash memory-based storage device shows different characteristic
according to its internal geometry or flash memory management scheme, namely FTL,
F2FS and its tools support various parameters not only for configuring on-disk
layout, but also for selecting allocation and cleaning algorithms.

F2FS FORMAT TOOLS: http://d-h.st/users/psndna88/?fld_id=34001#files (formating /DATA with these will wipe your internal storage in single shot !)
EXT4 FORMAT TOOLS: http://d-h.st/users/psndna88/?fld_id=34000#files (formating /DATA with these will wipe your internal storage in single shot !)
PSN TWRP v2.7.0.x (F2FS Modified):-
P5100 : HERE
P511x : HERE
YOU HAVE TO USE F2FS supported kernel like AGNi for now
TWRP Drawbacks:
1: it doesnt ask which filesystem to format, but if u have ext4 previously, wiping that partiton is done in ext4 and same with f2fs, so u have to use above tools once atleast for partitons of ur choice
2: it doesnt support restore of ext4 backups to f2fs formatted partitions, so u have to clean wipe to fully convert to f2fs (titanium backup is ur best friend)
3: I SUGGEST MANUALLY COPYING INTERNAL STORAGE DATA TO PC and making titanium backups before trying to format /data to f2fs
4: to flash rom to f2fs formatted recovery you have to edit the updater-script and put a # before the "format" line and # before all unmount lines and manually mount system and data in twrp prior to flashing any zip. (i will post detailed updater-script modifications lateron)
5: on formatting /data to f2fs from ext4 or vice versa, twrp fails to mount /data, reboot to recovery again and all will be fine
App Screenshot: (v2.8 4.2.2)
About LZ4 compression/decompression:
LZ4 is a very fast lossless compression algorithm, providing compression speed at 300 MB/s per core, scalable with multi-cores CPU. It also features an extremely fast decoder, with speed in GB/s per core, typically reaching RAM speed limits on multi-core systems.
ADVANTAGE OF LZ4 OVER SNAPPY = higher speed with almost same marginal cpu usage for Zram
