SlimKat with "All-F2FS" support

I have modified SlimKat to work with F2FS partitions. All credits for the ROM to SlimKat guys.
This is for "All-F2FS" that mean that /system, /cache and /data are formatted with F2FS.
This is needed to switch to "All-F2FS".
ROM contains my Kernel with "All-F2FS" support and other goodies.

Ported sl[aou]b from Linux 3.4
Ported timer and workqueue from Linux 3.4
Ported random from Linux 3.13-rc4
Ported rwsem from Linux 3.11
Kernel NEON Mode
Etc..Etc..
Added GPU OC (Franco way..)
Added Toggle for FSYNC
Revert CPU OC things (We don't need it and it was a bit dirty..)

One of the goodies of my kernel is that i was able to reclaim more 18MB of RAM for Android. As you can see in Settings we are now at 993MB.
MultiROM isn't supported as now because i need to patch it to work with "new" ram.


What is F2FS?

F2FS (Flash-Friendly File System) is a flash file system created by Kim Jaegeuk at Samsung for the Linux operating system kernel. 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.

Wonderful, can't wait to try it - thank you! Do you have any idea yet whether you'll have the time and/or inclination to keep up with future Slim builds?

Can you make a tilapia version pls? I also use slimkat and I would like to use the the new file system.

I've been using SlimKAT as well on my tilapia. It seems that overall, tilapia has been left behind on most ROMs for the N7. I don't know how difficult it would be since as far as I know the only difference is the existence of a radio, but if you could do this for us that would be awesome!

Can u please modify the latest OMNI ROM nightly or can u at least point out exactly what needs to be modified if it isn't extremely complicated like changing 100s of lines of code in the source?

Is it possible that there is something wrong with the rom's zip file?

I'm asking since I've tried installing it on my grouper multiple times, and each time I got stuck at the Slimkat booting animation. When I downloaded the latest weekly from the Slimrom site and applied your kernel and the g-apps, everything worked fine.

I will try something when i have some free time..Maybe i will contact one of you via pm for some tests..

I installed the grouper version on my tilapia ( I couldn't wait) but I had a little problem flashing gapps. I couldn't flash full PA gapps because there wasn't enough space on the system partition. I usually use PA stock gapps with slim ROM. When I reverted to the previous file system with your zip( it worked, I tested it :)) I flashed full PA gapps successfully.
Did you try to use art? For me it caused FC's.

(Thanks for testing the zip)

8GB device I assume?

yes, i said that because with other rom & stock rom, free space avalaible is 5.85 GB after fresh install, maybe it's caused by F2FS ?:p

    When is v. 3836 being released? as it is on the weekly builds on slimrom site dated 21 / 04 / 14, I realise you will have other things to do, just curious as to whether there is a reason you haven't released it yet?

    There is one reason. I worked hard on a new kernel that i wanted to include with new version. So i had to make sure that it works well at least for me. :D Sorry for the delay.

    Slim-grouper-4.4.2.build.4.6-WEEKLY-3836-F2FS.zip

    I'm just writing the link for the new release here. If you guys tell me that all work good i will push it to the first post.


    New kernel contains a lot of unique optimizations for our N7 made by me. I tested it for days and seems to work right. I even did some benchs (usually i don't them..) and seems that with Antutu we are around 15000 points..(Obviously without overclock..). There is nothing to configure or to tweak. It's to use as is out of the box.

    Updated first post with SlimKat 4.8.

    Kernel updated.
    - USB OTG Fixed
    - Optimizations
    - Battery improved

    :D

    Hey guys. I've just published an app that let you convert a Standard ROM to All-F2FS ROM without a computer. Directly on your phone/tablet.

    Convert To F2FS
    https://play.google.com/store/apps/details?id=com.runnerway.converttof2fs

    -lSpP8Rh6vRVew5L72u3ZEh7Vf4d6VDx2kul2ueIhfihJ2Cw0gyDbYiMHVnRI7A9X6A=h900-rw


    So you can convert yourself every ROM you want without troubles.
    Now it's easy to stay up to date with the ROM you like.

    Tested with:
    - SlimROM
    - Paranoid
    - Omnirom
    - Cyanogenmod
    - Etc..

    It cost very little, like a coffe.
    I think it's usefull and it's a good way to support my work.
    Thank you. :D
