First Thing First: How To Install Custom Kernel
1) You need to UNLOCK BOOTLOADER using one of these method. I'm NOT responsible of what you've decide. Please follow instruction carefully.
-> S1tool
-> Sony Mobile - Unlock Bootloader
2) Get this awesome tool called Flashtool and install. Dont forget to install usb drivers from "Drivers" folder too.
3) I assume you have download one of my kernel. Get into Fastboot mode. How? Do i have to repeat how? Press "Volume Up" while connecting your USB cable. you'll see Blue led.
4) Click "Flash" button on Flashtool, then select Fastboot Mode.
5) Choose "Select Kernel to Flash" and find your saved kernel. I'm not gonna find it for you.
6) Once completed, reboot device into system

THESE IS FINAL, NO LONGER MAINTAINED
HTML:
Those version below was a final version xKernel for Xperia Ray. I might on a new
device next week due someone already booked my ray. Ive planned to give the
last version using 4.1.B.0.587 but unfortunately source published by Sony was
corrupted. Sorry guys, i cant afford to keep my ray. This is it.
Thank you for using my kernel.

[SOLUTIONS]
[ SOLUTION: Graphic Performance ]
For those who using my kernel (ics beta kernel source build) may have some low performance in Official ICS (.562 FW). Trick to get better graphic performance :
1. Goto to Adreno Driver Thread by arcatarc
2. Download GpuDriverICS_4.1.A.0.562.zip and put in your SD
3. Flash OriginalAdrenoICSSony_4.1.A.0.562.zip using CWM.
4. Booting up
5. Enjoy some graphic improvement!
thanks to arcatarc for his update.zip
and hansip87 for found solution
please dont be lazy to hit the button for their effort.
[ SOLUTION: My Steps to prevent Superuser Issue in TB ]
Who has Superuser issue or Root Access after installing JJ's Rom, can try my steps. I never had issue with Superuser/Root Access after did these steps
Go to here --> #Solutions
Last night I was thinking, hey, when sirkay makes his kernel thread I ought to ask for sio scheduler.
... so here I am asking
Installing this touch recovery thing anyway, sounds like fun!
SOLUTIONS: Zram | Wifi Channel 12-14
[ SOLUTION: How to make simple ZRAM init.d script ]
1. Using Root Explorer, got to /sytem/etc/init.d/
2. press Menu then create new file
3. paste these in it
Code:
#!/system/bin/sh
sysctl -w vm.swappiness=60
echo '1' > /sys/block/zram0/reset
echo $((60*1024*1024)) > /sys/block/zram0/disksize
mkswap /dev/block/zram0
swapon /dev/block/zram0
4. close and save it as 99zram
5. set permission to 777 or "rwxrwxrwx" (tick all)
6. take note: 60*1024*1024 = 60MB zram disksize. if you want to set 30MB, change 60 to 30.
[ SOLUTION: To Enabled Wifi Channels 12-14 ]
1. using Root Explorer, goto /system/etc/init.d
2. open one of your init.d scripts, i suggest first in the list (Menu > Open in text editor)
3. paste line below
Code:
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "INSERT INTO secure (name, value) VALUES ('wifi_country_code', 'JP');"
4. close and save
5. reboot
note: to enabled channel 12-13 just change "JP" to "EU" or "ES"

I noticed that the touch recovery is set at 4mb sd cache, what's the best way to find out whats the best for my card? I'm using a class 4 32gb and I get those annoying soundbugs whilst listening to music in every set, 128, 1024, 2048 and 4096.
Thanks in advance
using root explorer, goto /system/etc/init.d, create new file name it as "75sdcard". paste this script and save. set permission to 777 (rwxrwxrwxr using root explorer). then reboot.
let see if it remove your soundbug.

You got that sound bug? I thought it only resides on slower CPU phone :/ I don't get a sound bug with 2048 kb set (only when the CPU is too stressed, some audio bug may occured, but not as bad as my old X10 Mini Pro)
Some general rule of thumb, SD class 6 and/or faster, 2048 kb and up. SD class 4 and/or slower, 1024kb and less.

Hey sirkay, you need to add some caution though when flashing these kernels. It seems that the kernel.is preloaded with busybox and root, but not the newest one. So it was lagging my phone (sudden freeze). My solution is to uninstall and reinstall busybox from market and fix root by updating it.

Does this work only on ICS? Can it be used on GB custom roms like rayonium?

Sirkay, You just WON.... ...Awesome...
Touch Recovery ?? .... You didnt let Ray users bow to Arc users... Thumbs up mate...
---------- Post added at 07:00 PM ---------- Previous post was at 06:31 PM ----------
Btw.. Is there anyway you can remove that Back and maybe Menu button...?
Not necessary but just asking coz ARC users have the benefit as they dont have touch keys but we Ray users already have touch and Menu back button.....
EDIT: Sorry That circle button is for click.. Thats Great.. I always hated pressing home key for a tap... I guess Back button is fine to remove...
Thank you for a great works. Working perfect here..init.d now working..
none

How to play with kernel
Here are some intructions/tips about how to play with the kernel.
Terminal is needed.
If you want to change the values,it needs su permission.
If you get 'Permisson denied',you need su permisson.
If the devices lost responses,hold power button 8s to reboot.
Simply,You can cd to the folder first,then do echos.
Then `???` stands for the number to input
Boot time
RoXSel boots faster than stock normally.
4.2.2
Code:
Stock: 8600ms - 8800ms
RoXSel: 8400ms - 8600ms
Report other versions !!
How to check boottime?
Code:
cat /d/boottime/summary
CPU Governors
OndemandQ ( Default )
Ondemand
Performance
Hotplug
SmartAss2
Lionhearth
Lulzativeq
Powersave
Intellidemand
Lagfree
Lazy
Interactive
Conservetive
Userspace
* Personaly,I use OnDemand(Q)
* OndemandQ is a new governor. It will hotplug cpu when screen turns off only.
* If you mind the battery life time,choose HotPlug. It hotplugs cpu frequently.
* LulzactiveQ, it will hotplug cpus
CPU Freqs
On JB,we cannot tweak min/max scale freqs via apps like SetCPU.
Here is the method.
Code:
cd /sys/power
For example: set 400Mhz as max limited
Code:
echo 400000 > cpufreq_max_limit
* When you switch on/off power saving mode, this tweak will be overrided.
IO schedulers
Noop ( Default )
Deadline
Cfq
Bfq
Row
Zen
Sio
Vr
* Personally, i use Zen
Frandom Module
Use CrossBeeder to enable frandom.
Deepest sleep state
Stock: 3 Default: 3
Deepest supported is 5.
To change:
Code:
echo 5 > /d/cpuidle/deepest_state
* PegasusQ ( hotplug governors ) works badly with 5
* OnDemand works well with 5
* Please note that it wont increase the using time but standby time.
To check the cpuidle state:
Code:
cat /d/cpuidle/stats
USB VBus
( v2+ )
This can enable the internal vbus power supply for usb devices.
But the phone still cannot recognize our usb devices now.
You can use it for fun,like charging for other devices, using usb fan...
To enable :
Code:
cd /sys/kernel/abb-regu
echo 1 > VOTG
* Say 0 to VOTG to disable
* Plug yoru cable first,then enable it
zRAM
zRAM is optimized for Android.
It is not lazy anymore.
Using zRAM will take a little CPU,because it needs to compress/decompress memory.
Recommended compressing about 18% of RAM,about 100mb
Setup disksize first: (example: 96mb= 96×1024×1024)
Code:
echo 100663296 > /sys/block/zram0/disksize
* Larger size more RAM will be compressed.
* Too large size might make phone lag
Enable:
Code:
mkswap /dev/block/zram0
swapon /dev/block/zram0
To check how many does it use:
Code:
cat /sys/block/zram0/num_reads
cat /sys/block/zram0/num_writes
* You can get other info in its sysfs
Swap
Format/resize your SdCard via computer first.
Enable:
Code:
mkswap /dev/block/mmcblk1p1
swapon /dev/block/mmcblk1p1
Init.d script
Put some scripts (any name you like) in init.d folder with permisson 0777 (rwxrwxrwx) (at least has read and exec permission)
Scripts with right permisson will be runned when system boots.
Charger control
Please note that this control can damage your battery/phone.
If your battery/phone damaged,read the top of #1 post.
Lower current makes the charging longer,but protects battery.
Too high current can burn your battery!
I recommend you that dont set the max limited current over 900mA.
AC Maximum current: (stock: 600 , min: 0 , max: 900) mA
Code:
echo ??? > /sys/kernel/abb-charger/max_ac_c
USB Maximum current: (stock: 600 , min: 0 , max: 900) mA
Code:
echo ??? > /sys/kernel/abb-charger/max_usb_c
* The control only accepts values like 0, 100, 200 ...
* Set usb current to 0,the phone wont charge in usb port,but transmits data.
Track driver memory [advanced] :
Code:
cat /sys/kernel/abb-charger/stats
To get the charging current:
When you plug charger:
Code:
dmesg | grep -i ab8500-charger
Real charged notification
To be honest,it needs to check manually.
Code:
cat /sys/module/abb_chargalg/parameters/eoc_status
* You can use Rootexplorer to view this file.
* When it says "First full charging reached",then the UI should show you charged 100%
But it is not the real full charged.
* When it says it is the real full charged,you can unplug the charger.
* When you are charging and do a reboot will reset the counter.
* According to my experiments,it needs 1-2 hours to charge to real full.
MMC SIP CRC
( v2+ )
Disabling SPI CRC can improve mmc performance (10% ~ 30%)
But phone may freeze randomly
Code:
echo 0 > /sys/module/mmc_core/parameters/use_spi_crc
Camera LED Flash
( v2+ )
HIghlight mode for assistive light, enabling this for a long time will heat up your device, be careful!
Enable:
Code:
echo 1 > /sys/class/camera/flash/highlight
Disable:
Code:
echo 0 > /sys/class/camera/flash/highlight
Fsync Control
Get current status:
Code:
cat /sys/kernel/fsync/mode
FSYNC modes:
Code:
0: fsync on
1: fsync off
2: fsync dyn
Disable FSYNC:
Code:
echo 1 > /sys/kernel/fsync/mode
* Disabling fsync can improve io performace,
but it can make the data which hasnt been written lose when a sudden poweroff comes.
* Disabling fsync or enabling dyn_fsync will make param driver fail to store data
That means your "reboot recovery" will fail.
Enable Dynamic FSYNC:
Code:
echo 2 > /sys/kernel/fsync/mode
* Dynamic fsync will sync all buffers when screen turns off,
* If there is a heavy io load,the screen might get stuck for seconds.
* This is an experimental feature.
Mali GPU
Mali debug level
Disabling can speed up a bit
Code:
echo 0 > /sys/module/mali/parameters/mali_debug_level
* Higher level,more messages will be printed in dmesg, system will slow down
Mali L2 max reads control: (Stock:28kb,Default:48kb(max))
Code:
echo xx > /sys/module/mali/parameters/mali_l2_max_reads
* Some values will slow down graphics
* If not sure,keep default
Mali PM sampling rate: (Default: 1000ms)
Code:
echo xx > /sys/module/mali/parameters/mali_pm_sampling_rate
Mali PP scheduler tweaks: (Default: disable)
Code:
echo 1 > /sys/module/mali/parameters/mali_pp_scheduler_balance_jobs
* Enabling this,Some places will over ahead,choose by your self
Mali Utilization sampling rate: (Stock:500ms,Default:1000ms)
How often report a mali utilization.
Code:
echo xxx > /sys/module/mali/parameters/mali_utilization_sampling_rate
* Keep this default if unsure.
Mali Utilization control
(Default: low_to_high 192 high_to_low 64)
Our driver will report a mali utilization frequently.
This utilization(range: 0~255) means the load of mali.
If utilization is bigger than low_to_high ,driver will request higher hardware performance(highest APE/DDR OPP).
If utilization is smaller than high_to_low ,the driver will store the requested OPP(uses low OPP).
OPP can be understood as freq simply.
To check mali utilization values:
Code:
echo 5 > /sys/module/mali/parameters/mali_debug_level
cat /proc/kmsg | grep -i utilization
When it says SIGNAL_HIGH,it will request highest OPP.
When it says SIGNAL_LOW,it will request lowest OPP.
Press Ctrl+C to stop printing.
You can reduce low_to_high to trigger higher OPP requirement.
For smoothness and less powersaving:
Set low_to_high between 100-192.
Code:
echo 120 > mali_utilization_low_to_high
Mali max preemptive allocated max memory size:
Default is 16mb(16*1024*1024), bigger max size more throughput.
But when this value is too big, no more throughput.
For example: 48mb = 48*1024*1024
Code:
echo 50331648 > /sys/module/mali/parameters/pre_allocated_memory_size_max
EGL Driver
To use Mali hardware egl driver only:
Edit /system/lib/egl.cfg
Code:
0 0 android
0 1 mali
To
Code:
0 0 mali
Then remove libGLES_android.so
* Recommend to backup these files
* According to my feelings: after disabling sw egl driver,UI is faster
Logcat
Well,we have made android logger(logcat) as module to free more RAM.
Some guys request logcat.
Now we provide you a workaround:
Create a new init.d script:
Code:
#!/system/bin/sh
insmod /system/lib/modules/logger.ko
or
Flash this ZIP
Then you can use logcat command.
Almost tweaks will be restored to default after reboots.
So you can make your tweaks as init.d scripts to apply them when boots.

What are these an do I need it I'm running rootbox
Sent from my GT-I8160 using xda app-developers app
Faster with CM10 than CM10 with his stock kernel?
EDIT:
OP: @Rox = Roberthinio??
Ok IDK nothing about kernel. I use CM10 from @dh.harald. If i use this kernel, the performance will increase? And i use mod vold.fstab from MIUI beta rom, will it causing complication when i flash this kernel? Or i should flash this kernel with fresh CM10?
Thanks in advance, congratulations for the elaboration
good job :fingers-crossed:
Thank you guys. I'll give a try on slim bean.
On stock JB phone does not boot, its blocked at samsung blinking logo. Advices?

What is needed:
Samsung GT-I8160 (Jellybean)
AOSP ROM (CM, P.A.C, Slim, RootBox, LiquidSmooth...)
Some Android experience
This is confusing, does it run on stock JB roms? Or is intended olnly fir custom roms?

read what is needed before you flash. to boot phone flash kernel.bin.md5 from one of firmwares using odin
Not needed I had cwm backup of my rom and just restored stock kernel phone booted ok. Please modify first post and specify that this kernel is compatibile ONLY with custom roms.

Don't mean to sound like a noob but is it safe to use on top of tweaks such as Project Injection?
Yes. Also if you use crosbreeder you can enable frandom

Thanks for the quick reply. I'll be pairing up this kernel with LiquidSmooth as soon as call volume is fixed. :good:
I'm trying now. This is ****** handsome! You put hotplug governor, my battery say tahnks to you
Maybe one little bug: on powersave frequency doesnt remain at 200mhz. And if i set frequency min 200 MHz - max 400mhz the 800mhz step continue to work, eventi if i choose userspace.
I'll try with no CPU frills.
Good work mate!

Changelog
(old changelog)
R2.10
Build from R2.6 sources with re-added all changes in LiveOPP, cpufreq_limits module, some interfaces from 2.9.x (usb sw reset, PonKey emulator on voldown/up).
R2.9
Mali OC module v2.0:
added interfaces boost_hispeed1, boost_hispeed2.
added interfaces mali_threshold_freq_down and mali_threshold_freq_up
(new interfaces manual)
1) mali_threshold_freq_down/up:
echo new value to tweak it:
Code:
echo 150 > /sys/kernel/mali/mali_threshold_freq_up
2) mali_boost_hispeed(2)
Use command
Code:
echo idx=X > /sys/kernel/mali/mali_boost_hispeed2
to tweak its freq.
following command is to tweak its threshold:
Code:
echo threshold=220 > /sys/kernel/mali/mali_boost_hispeed2
partially re-enabled touchboost (it actually was enabled even on 2.7.4, but I forgot to mention)
reverted suspend/hibernate/freezer etc. commits to hopefully fix reboots issue in deepsleep
fixed APE_25_OPP (in suspend it actually used APE50 previously)
minor fixes in cpufreq_limits driver
R2.8
Mali OC module v2.0(detailed description in 3rd post):
added interfaces boost_hispeed1, boost_hispeed2.
added interfaces mali_threshold_freq_down and mali_threshold_freq_up
partially re-enabled touchboost (it actually was enabled even on 2.7.4, but I forgot to mention)
reverted suspend/hibernate/freezer etc. commits to hopefully fix reboots issue in deepsleep
fixed APE_25_OPP (in suspend it actually used APE50 previously)
minor fixes in cpufreq_limits driver
(2.7.6)
- fixed broken GPU scaling algorithm (removed /sys/kernel/mali/mali_scaling_dynamic)
(2.7.5)
- partially reverted LiveOPP voltage autocalibration
- fixed unstable mali tunables and added interface mali_scaling_dynamic
Code:
echo 1 > /sys/kernel/mali/mali_scaling_dynamic
When mali_scaling_dynamic is used, mali will scale between mali_boost_low and mali_boost_high using all steps between these mentioned. mali_stats provides statistics about mali utilization on each step.
- removed some GPU freq steps
(2.7.4)
- new governor Dynamic (thanks to mkaluza)
- new GPU scaling algorithm (thanks to 1N4148 ) - ondemand-like GPU governor
- LiveOPP: reworked avs-based varm recalibration algorithm
(2.7.3)
added governor OndemandPlus (thanks to boype)
removed governors with hotplugging support
added interface to tweak PLLDDR freq on suspend:
Code:
echo on > /sys/kernel/cpufreq/pllddr_raw
To control freq are used raw PLLDDR register values:
Code:
echo suspend=0x000050158 > /sys/kernel/cpufreq/pllddr_raw # 675 MHz
Code:
echo resume=0x000050168 > /sys/kernel/cpufreq/pllddr_raw # 798 MHz
PLLDDR freq can be checked via
Code:
cat /sys/kernel/liveopp/pllddr
Settings applies after 3 sec after suspend/resume.
Too low suspend or too high resume value may cause reboot. Please note that this setting still experimental and unstable itself, so it's disabled by default.
adjusted some GPU OC defaults
fixed BT issues
(2.7.2)
- fixed pllddr_cross_clocks instability
- removed unneeded DDR_50_OPP requirement on screen on (should prolong battery lifetime).

Kernel Tweaks:
(GPU/CPU undervolting and related tweaks)
Undervolting the CPU/GPU will bring battery savings but possible instability.
1) to undervolt CPU use ChronoKernel app or via init.d scripts:
Code:
echo *cpufreq* varm=xx > /sys/kernel/liveopp/arm_summary
for example, following sets voltage varm=0x10 for 200 MHz:
Code:
echo 200000 varm=0x10 > /sys/kernel/liveopp/arm_summary
or
Code:
echo 200000 varm-=10 > /sys/kernel/liveopp/arm_summary
(default varm voltage for 200 MHz is 0x1a but, code above sets 0x1a - 0xa(10) = 0x10 )
2) to undervolt GPU use init.d script:
Code:
echo x vape=yy > /sys/kernel/mali/mali_dvfs_config
Example:
Code:
echo 2 vape=0x1c > /sys/kernel/mali/mali_dvfs_config
"2" stands for DVFS idx (look at mali_boost_high/mali_boost_low).
To prevent overriding of such settings by ChronoKernel app, add line to your init.d script after GPU undervolting
Code:
chmod 444 /sys/kernel/mali/mali_dvfs_config
Don't change voltage of both GPU/CPU at the same time - otherwise if you'll get reboot if won't know what it caused. The same is for different frequencies - if you'll change voltage of too many steps you won't know which frequency caused reboot. It's not easy process, though, following method simplifies it: https://github.com/mkaluza/i9070_kernel_CoCore-E/wiki/Undervolting-janice .
3) Custom LiveOPP table.
By default some LiveOPP steps such as 100, 200, 500 ... MHz aren't used. You can re-enable those by following way:
Code:
echo 200000 enable=1 > /sys/kernel/liveopp/arm_summary
Or use CK app instead. Don't enable it unless it uses the same voltage as 400 MHz. The same is for the rest frequencies - until some of them uses same voltage, no point to enable steps with lower freq. I've added 100 MHz just to further make some tests with it once again. It can't use lower varm than 200 MHz - that's why it's disabled by default. Furthermore, not all phones well keep undervoltage, that's why 100-400 MHz steps uses same stock voltage varm=0x1a.
UPD. thanks to @borkins for this nice editor LiveOPP ARM steps: http://forum.xda-developers.com/showpost.php?p=60311291&postcount=2921
(CPU freq management tweaks)
CPU freq. limiter for screen OFF, adjust it via:
Code:
SYSFS=/sys/kernel/cpufreq/cpufreq_limits_on_suspend
echo min=100000 > $SYSFS
echo max=400000 > $SYSFS
echo on > $SYSFS
Too low frequency may cause freezes after wakeup and sound scrathes. If you use Dynamic govermor, it make no sense to use cpufreq limiter, because Dynamic already takes care about CPUfreq usage optimization. For more, read wiki.
Input boost
This feature has been originally written by zwliew.
Not all governors support input boost. Supported governors: ondemand, interactive, conservative, ZenX, lionheart and some others. Dynamic governor has its own boost interface.
Default boost frequency is 400 MHz.
Code:
echo 450000 > /sys/kernel/cpufreq/input_boost_freq # echo '0' to disable
echo 35 /sys/kernel/cpufreq/input_boost_ms
(BackLight Notification)
To configure time intervals of BLN blinking type(bln_ondelay stands for time of blink and bln_offdelay - delay between two blinks):
Code:
echo bln_ondelay=500 > /sys/kernel/bln/blink_mode
echo bln_offdelay=6000 > /sys/kernel/bln/blink_mode
Make sure BLN enabled:
Code:
echo 1 > /sys/class/misc/backlightnotification/enabled
# to enable bln_wakelock.
echo on > /sys/kernel/bln/bln_wakelock
Use /sys/devices/virtual/misc/backlightnotification/blink_mode to changes modes.
Blink modes:
0 = no blinking
1 = blink backlight only
2 = blink backlight + rear cam flash
3 = blink rear cam flash only
(Module autoload)
Now there is a simple way to load modules at boot. Just move needed modules to /system/lib/modules/autoload and reboot device(or execute /etc/init.d/00autoload)
(DDR overclock)
This feature has been developed by me and allows you to improve DDR and GPU performance. Please note, that DDR OC might work unstable and cause filesystem corruption. Though, DDR clock of 975 MHz has been highly tested and should work fairly stable on most devices.
Overclocking DDR over 975 MHz is highly NOT recommended, especially in case if you not sure that you can deal with possible consequences.
How to OC DDR:
1) by using
this script .
2) by using Terminal Emulator(in example below 975 MHz):
Code:
echo 0x5017f > /sys/kernel/liveopp/pllddr_oc_on_suspend
This setting will be applied right after disabling screen.
(Minimum APE/DDR OPP on screen on)
This feature has been developed by me and allows to set minimum APE/DDR OPP states which are used when screen is ON. APE controls many systems such as an image, video, audio system etc. DDR OPP determines performance of DDR. Default values are APE50 and DDR50. Lower states(APE25/DDR25) reduces power consumption, but may cause graphical glitches like screen blinking or filling it by vertical grey lines. If you don't have mentioned effects, it's recommended to use APE25/DDR25:
Code:
echo ddropp=25 > /sys/devices/pri_lcd_ws2401.0/mcde_screenon_opp
echo apeopp=25 > /sys/devices/pri_lcd_ws2401.0/mcde_screenon_opp
* if you don't have folder /sys/devices/pri_lcd_ws2401.0, use /sys/devices/pri_lcd_s6d27a1 instead.
(Screen refresh rate)
This feature has been developed by cocafe and modified by me. Lower lcdclk frequency cause less power usage, but too low values makes system unusable.
Following command allows to change screen refresh rate:
Code:
echo x > /sys/kernel/mcde/lcdclk
use
Code:
cat /sys/kernel/mcde/lcdclk
to see supported lcdclk modes. Default mode is 60 Hz which is recommended in most typical cases. If you've screen tearings, blinking etc. change resresh rate mode to "60+ Hz":
Code:
echo 0 > /sys/kernel/mcde/lcdclk
(ABB charger tweaks)
added tweakable interfaces for termination current. To adjust it type(just an example):
Code:
echo 90 > /sys/kernel/abb-chargalg/termination_curr_1st
echo 70 > /sys/kernel/abb-chargalg/termination_curr_2nd
curr_2nd should be less or same as curr_1st. Lower values prolongs battery lifetime, but also slows battery charging.
Default values are curr_1st == curr_2nd == 150 mA. Please note, too low values maybe aren't usable.
(Dynamic FSync)
This feature has been developed by Faux123 and allows to dynamically manage the synchronous writes performed on file system (FSync).
It uses asynchronous writes when the screen is on, instead of synchronous writes, to have better performance and a slightly lower battery drain, while when the screen is off the synchronous writes are re-enabled to flush all the outstanding writes and prevent possible data loss.
How to enable/disable the Dynamic FSync (default enabled):
1) By downloading and using Trickster MOD
2) By directly editing the file /sys/kernel/dyn_fsync/Dyn_fsync_active and setting 1 to enable the dynamic fsync, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic fsync feature
Code:
su
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
- Or run this command to re-enable the dynamic fsync feature
Code:
su
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active

(Software CRCs)
Disabling software CRCs gives you a slight bump(10-30% is what they say) of MMC performance, at the cost of a possibility of your Ace 2 freezing randomly.
Code:
echo 0 > /sys/module/mmc_core/parameters/use_spi_crc

(Dynamic dirty page writebacks)
This feature has been developed by Christopher83 and allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off.
It is based on a commit of Francisco Franco, but instead of using hard coded values and of disabling at all the dirty page writebacks while the screen is on (possibility of data loss).
By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
How to customize the dynamic dirty page writebacks feature (default disabled):
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature, set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page writebacks when the system is active (screen on), the default value is 1500 centisecs (15 seconds)
- dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off), the default value is 500 centisecs (5 seconds)
1) By directly editing one of the file written above inside /proc/sys/vm and setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic dirty page writebacks feature
Code:
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
- Or run this command to re-enable the dynamic dirty page writebacks feature
Code:
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
- Run this command to set customize the two intervals (30 seconds while the screen is on, 10 seconds when the screen is off)
Code:
echo "3000" > /proc/sys/vm/dirty_writeback_active_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_suspend_centisecs
(Storages switch)
By default, this kernel comes with internal and external storages switched. You can revert this behavior, by changing the line
Code:
use_swap=1
to
Code:
use_swap=0
in file /ramdisk/fstab_specs.txt and flashing the kernel package. This setting will remain until you format /ramdisk partition.

How to install kernel with F2FS support:
For those who don't know what F2FS is, check these links out:
General info
Benchmarks
Warnings
1. Make sure you have a standard kernel for backup that uses ext4 just in case. If anything goes wrong, just install the backup kernel and reboot to recovery.
2. You will have to wipe your /data and /cache partitions for this. Basically factory reset.
3. For 2, you could try to backup data and restore after formatting. I haven't tried this but I could work.
Click to expand...
Click to collapse
Installation method of kernels with full F2FS support:
Before installation make sure that you have at least ~25% free space on each partition that will be formatted to F2FS.
for CWM:
make backup
format /system partition to F2FS (and also /data and /cache if you didn't do it before)
restore /system partition
for TWRP
disable md5 generation
make backup of /system
find backup folder, run terminal and rename file system.ext4.win to system.f2fs.win (it won't work via filemanager)
Code:
mv system.ext4.win system.f2fs.win
format /system as f2fs
restore backup
Then install kernel.
To install kernel on ROM that isn't supported by installer:
(supported ROMs):
Stock ROM 4.1.2
CyanogenMod 10.1*
CyanogenMod 10.2*
CyanogenMod 11*
CyanogenMod 12
* most ROMs that based on this ROM are also supported. Despite of that some ROMs are supported, they can work incorrectly due to difference in their initramfs scripts(ramdisk).
1. Install needed ROM first,
2. Type following command in terminal emulator:
Code:
cd /
find . -xdev | cpio -o -Hnewc | gzip -9 > /sdcard/x.y.z.cpio.gz
where x.y.z is OS version (for example - CM11-based ROM - 4.4.4.cpio.gz)
3. put this file in installer at osfiles/x.y.z/ (e.g. osfiles/4.4.4/4.4.4.cpio.gz)
4. install kernel
To install a new ROM that is not F2FS compatible:
Use EXT4 to F2FS converter script
or edit the updater-script as follows
(manual method)
1. Replace strings
"mount("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");"
with string
"run_program("/sbin/busybox", "mount", "/system");"
2. Replace string
"format("ext4", "EMMC", "/dev/block/mmcblk0p3", "0", "/system");"
with string
"run_program("/sbin/mkfs.f2fs", "/dev/block/mmcblk0p3");"
3. Add string
"run_program("/sbin/busybox", "mount", "/data");"
after strings
"run_program("/sbin/mkfs.f2fs", "/dev/block/mmcblk0p3");"
"run_program("/sbin/busybox", "mount", "/system");"
4. Add string
"unmount("/data");"
before string
unmount("/system");

chmod 0644 /sys/module/lowmemorykiller/parameters/debug_level
echo "0" > /sys/module/lowmemorykiller/parameters/debug_level;
works miracles in my case, especially second one, imho it would be hard to use different values, i was trying different setups for YEARS(with this machine), so it is not just random throw. Bigger LMK REALLY makes things worse here. It usually has tremendous influence over fluidity of gui, and whole sys.

This kernel based on stock CM kernel by TeamCanjica, and it's have same changes.
Damn, I was so excited to see a new kernel, but I noticed that it's actually for 4.1.2. I almost flashed it on a 4.4.3, not that it would have been such a tragedy.
Is there gonna be a version for the KitKat ROMs?

OK. I've got another question for you. Are you gonna add "lagfree" between the governors you already added, because that's probably one of the best governors a kernel can have ?
This is for stock samsung JB?
yes it is
Even if in the download section it says 4.4.2, I flashed the kernel on a Carbon 4.4.3 and it's working like a charm. The only thing that doesn't show up correctly is both frequency bars in "performance". It shows 0MHz max, 0MHz minimum, but if you set the minimum to 600MHz, for example, the frequency will run at 600 minimum, even if it shows 0.
five attempts and each time bootloop and recovery keys do not work.

If you added "lagfree", you'd be the first on to do it, so it would obviously be amazing and it would make you a better developer than others, of course.
EDIT: About the frequency thing, for me it shows 0MHz probably because I've got kitkat 4.4.3. Everything else's working fine.

I have no idea what caused this problem. Because on stock kernel and CM kernel i did not have this problem. Try to remove this folder and create text file with same name.
Would love to see lag free if anyone could make possible

Lite-KAT with working ART
Very light ROM
DOWNLOAD LINKS: http://d-h.st/RGz
NOTE:
Kernel with GPU OC 476 Mhz (working not to all). If you have not overclocked the GPU, you can flash the kernel phoenix5.
At the kernel added function to force a reboot by holding the power buttonfor 8 seconds. No need to remove the battery.
In kernel included intelli_plug, sweep2wake/Sweep2Sleep, doubletap2wake
To enable/disable functions used script kernel_settings in systems/etc/init.d (open in RootExplorer kernel_settings in a text editor)
1. in line echo 0 > /sys/android_touch/sweep2wake
change 0 to 1 to enable Sweep2Wake only
change 0 to 2 to enable Sweep2Wake + Sweep2Slep
change 0 to 3 to enable Sweep2Slep only
0 - disable
2. In line echo 0 > /sys/android_touch/doubletap2wake
change the 0 to 1 to enable doubletap2wake
0 - disable
This script will save the settings after a reboot, no need to use third-party programs
To activate ART:
Go to settings - about phone - and quickly press a few times on the "Build number". And change from libdvm.so to libart.so

This is just a proof of concept for "if we like a Kernel but don't like the default setting and too lazy to use kernel adiutor to apply the desirable setting"
Basically I just changed the Late Autumn installer zip using the goodies from Zetsubou. So this is a Late Autumn kernel with my modifications to ramdisk.
Here's the difference:
1. Enable doubletap2wake by default
2. Set CPU maximum frequency to 1401600
3. Set CPU minimum frequency to 200000
4. Set GPU maximum frequency to 550000
5. Set GPU minimum frequency to 100000
6. Enable MSM CPU hotplug by default
7. Disable GPU Adreno idle by default
Warning:
Only tested on lineage-14.1-20170126-nightly-wt88047 !!
Make sure to install this kernel on top of that rom stock kernel...
And make sure to clear the kernel adiutor setting too... You can set the others later, I did a dirty trick to let the CPU minimum frequency goes to 200 with interactive governor. I don't know if others got this weird problem, in my device set min freq to 200 didn't work with interactive governor.
How to install:
- Make sure you have lineage-14.1-20170126-nightly-wt88047 rom with the stock kernel
- Flash from TWRP like usual

replace_string init.qcom.power.rc "scaling_min_freq 200000" "scaling_min_freq 800000" "scaling_min_freq 200000";
replace_string init.qcom.power.rc "1 200000:85" "1 800000:85" "1 200000:85";
# end ramdisk changes
2. Add file init.zetsubou.rc :
Code:
