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

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):- (NEW 2.7.0.3 UPLOADED)

P3100 : HERE
P311x : 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

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

Nice looking forward to test the kernel. Good work buddy :)
Wanna know if the swap support is default enabled??

Re: [KERNEL][STOCK 4.1.2] AGNI pureSTOCK kernel (OC SUPPORTED)

Our processor can work on 1.2ghz without problems? Most processor come with underclock factory, and can increase the frequency smoothly on tab 2 P3100 also exists this limitation?

yes for most people it works nicely on ~1.35-1.42 GHz
still it depends on device to device

Welcome robin......

Psn has made a great job......we r running now with agni......
And I will announce that this is the official SungsonicHD kernel from now....

So dont expect support for other builds.....except stock and agni......& blackhawk

I intentionally downloaded agni max oc from op link and I flashed it o my tab.....

Amazing speed its working perfect with out any wipe. ....

So I can confirm that there is no boot issues with all versions of agni

no... but its safe to test capability of ur device on oc first then progress to maxoc

    ================================================================================
    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):- (NEW 2.7.0.3 UPLOADED)

    P3100 : HERE
    P311x : 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

    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
