I/O Scheduler
Code:
noop, deadline, cfq, vr, and sio
Init.d Script:
*requirement : busybox
*recommended : lastest busybox
Custom Bootanimation:
* Put the bootanimation.zip in /system/media with right permissions.
* If there isn't any custom bootanimation, kernel will load Samsung official bootanimation.
CIFS support
i put cifs.ko in "/lib/modules/2.6.35.7/fs/cifs"
not be loaded by default for power saving
zRam:
* zRAM must be enabled by script/command.
* put this script in init.d
Code:
#!/system/bin/sh
# enable zRAM script
# zRAM Swap Disk Size: 64MB(64*1024*1024)
disksize=67108864;
# Set Size to system
echo $disksize > /sys/block/zram0/disksize;
# Enable Swap (Need BusyBox installed)
busybox mkswap /dev/block/zram0;
busybox swapon /dev/block/zram0;
SWAP:
*SWAP must use with a SWAP partition in sdcard.
Code:
mkswap /dev/block/mmcblk1p2
swapon /dev/block/mmcblk1p2
NTFS:
* Need a binary file "ntfs-3g". download here
* I put it in the flashable zip already.
Mali Tweak:
* Increased L2 cache max reads ( 28k -> 48k )
* Increased OS memory for buffer. ( 6m -> 10m )
* Decreased Job runtime (5000)
* Increased Mali Mem ([email protected] -> [email protected])
Readahead Limit
Code:
Limit default readahead size for small devices.
disk size readahead size
1M 8k
4M 16k
16M 32k
64M 64k
256M 128k
1G 256k
4G 512k
16G 1024k
64G 2048k
256G 4096k
Fsync Controler
Enable/disable single file/filesystem sync.
/sys/class/misc/fsynccontrol/fsync_enabled
enable = 1, disable = 0 (default enabled)
example init.d script :
Code:
#!/system/bin/sh
echo "0" > /sys/class/misc/fsynccontrol/fsync_enabled
Disabling single file/filesystem sync increases the risk of a data loss on a crash/freeze and potentially can lead to other side-effects.

use cmd "free" in terminal emulator
you can see zram file in /sys/block/zram0
if you need zram please dont use script to make swappiness 0 (default : 60)
"/proc/sys/vm/swappiness"

ok, after i test flash my kernel when i use Kyrillos rom and twrp 2.3.1.1 i dont have any problem.
i flash kyriloss rom, i flash my old kernel (twrp 2.3.1.1), and then i restore my data.
after that I flash my new kernel (twrp 2.2.1) and i dont have any problem.
i use Odin3 v3.04 to flash my kernel via odin
try to use dd cmd (dd if=/sdcard/kernel.bin.md5 of=/dev/block/mmcblk0p15)
