[Galaxy S II Android Development] dorimanx:
Kernel Info about Tweaks / Mods

Here I will post about things that exist in kernel

.

First of all here are some guides made by VOKU also developer for this kernel.

Android: How to report bugs

How to use "ADB" - Command Line Tool

You get ZRAM SWAP.

In short, it's compressed RAM, that by using our mighty CPU compress 150MB of Real RAM into 300MB ZRAM!

This is simple math:

we have 848MB RAM, + 300ZRAM - 150 Needed for ZRAM = 1GB RAM :)

You can see it work by entering terminal app, or connection by ADB

And type:

free

you will see this..

root@android:/ # free
total used free shared buffers
Mem: 848164 801800 46364 0 13456
-/+ buffers: 788344 59820
Swap: 292968 23420 269548

in SWAP filed you see it exist and works!

Also there is one more advanced check :)

type:

su

zram_stats

you get:

127|root@android:/ # zram_stats

You see 3 ZRAM swaps each 100MB and they work in load balance!

All filled/released in one push, it's fully auto! it's will help on heavy RAM load!

==================================================================

Touch Recovery:

Made by ELITE DEVELOPER Gokhanmoral!

I have added tweaks and my configurations.

You can move in menu by finger, and by pushing arrows at the bottom, also hard keys work.

You can have 2 ROMS installed in one phone :)

See menu and check for full instruction on Developer Thread!

You can backup and restore / format / mount / install from ZIP / or from zImage!

You can set / reset your kernel profiles

there are 3:

Battery saver: reduced performance, but long battery life.

Default: normal performance, normal battery life

Performance: Boosted allot for performance, but faster drain of battery.

In order to use performance profile and not to drain your battery too much,

you need to set profiles in any app for CPU tweaking, that can give you profiles for:

Screen ON

Screen OFF

ON CALL

ON LOW Battery.

For screen ON you can use Full OC (200-1500) and have fun.

On Screen OFF: use 200-800/1000 speed

On Call use: 200-800 to save power.

On low battery use 200-1000/800/500 as you like..

================================================

You get tuned SQLite for CM9 or PURE ICS ROMS.

Its set to reduce the "sync command" when writing and reading tables in apps and system data.

So it's will "sync" on finish write, and not every small operation that its doing.

By this, read/write ( I/O) performance boosted allot!

If you install any other kernel after my, the sqlite will remain in ROM till ROM will be replaced.

================================================

More to be added later.

Kernel 1.0 -> 5.2

*Restored lot's of code that i and voku ported, to restore stability, much from that code was exp, so it's moved to EXP branch, i will test it offline.
*Changes to cortex for stability, see git.
*Messed with profiles save, should be ok now.
*Improved stability!
*Improved performance!
*Updated to 3.0.38!
*Fixed GPS
*Added wifi supplicant tuning to extweaks and to cortex.
*Added FIX for Korean GPS
*Added BT fix for SAMMY 4.0.4 ROMS by Gokhanmoral! TNX!
*More code porting for better deepsleep! and network fixes.
*Tuned hyper gov and renamed to HYPER!
*Updated to Samsung Update 5 + 6
*Lots of changes to TVOUT driver, it's may now work on custom roms!
*Removed ondemand, HYPER is the same gov but more advanced!
*Fixed intellidemand now it's stable.
*Ported more code fixes from 3.5-rc7
*Added new tweaks in extweaks and converted many to checkboxes.
*More patches to WIFI driver.
*Battery life improved allot! thanks to code changes that put more drivers to sleep!
*Removed KSM and ZCACHE from config, ZCACHE is damaged after merging with kernel 3.5-rc7 and KSM eat battery and dont really help. no big change in performance, still fast and smooth. (zcache no longer used in 3.x.x so we disable it too)
*Kernel is stable! 2 days with full cortex and performance profile.
*Updated to 3.0.37!
*I have ported lots of code changes from kernel 3.5-rc7 (about 2000+ code lines changed)
all about file system and cache memory and compression.
*VOKU has ported lots of new code for process control and kill + memory control. from 3.1.Y
*Fixed wakeup booster, it's more smart!, now i boost the freq to max but with your GOV not with performance, and add +25mV to all steps for time that wakeup booster works, then it's will set speed to normal and reduce voltage by -25 and all will be as you set.
*Cleaned code from unused functions.
*Extended light sensor and battery sensor pulling time, to reduce battery use, and CPU use (done by voku)
*Tuned voltage for HIGH steps 1000 --> 1500 added more +25mV each. for stability.
*Fixed the Touch keys timeout stuck at 5 sec. now should obey your settings.
*Added check if cortex background process is OFF or ON for real.
*Added new GOVs intellidemand and wheatley they are good for battery save, and can be fast if tuned via setcpu app! or they SLOW by default but very smart.
*Fixed all GOVS code about idle time statistics and wait for IDLE, should help reduce battery drain.
*Restored some define values to default, this small things can make big problems, we made some changes to them without fully understanding if it's OK or may damage some thing, like front camera!
*Kernel size is FULL, 8.10MB so very soon i will have to cut some tuning to gain more room for code changes...
*Fixed BLN still ON after main BLN switch off!
*Fixed small bug in kernel optimization.
*Tuned brightness for simple auto brightness (modded by VOKU)
*Improved stability and performance.
*File system corruption protection. by using FSYNC function to sync all changes to file system more often.
Added extweaks MISC option to disable the FSYNC to get little more performance, but reduce to less safe from damage file system (DEFAULT for all KERNELS!) this function is external! option will be updated only on reboot! not as you set it.
*Removed cortex background process for default and battery profiles, so user can use it or not. see extweaks, (without cortex, wake up booster + sleep gov change + dynamic GOV modding will not work!) for some ROMS, it's GOOD! since they get SOD all day with cortex ON, so try without, if OK, try with, if OK, have fun, if SOD, disable again.
It's ON for performance profile!
*Battery life improved.
*Added code fix that reduce CPU usage on idle to 1~15% on 100Mhz! was 15~30% now more battery will be saved.
*Rebuilded the root add/remove now it's used as buttons. install , remove , check
*Retuned Touch screen CODE, screen will not stuck now, 70% of SOD, not really stuck the phone, it's only the screen stuck! via adb i see that all OK! and system working as was, so now problem is fixed!
*New code fix for WIFI, now if not used and disabled in ROM, driver will cut power to WIFI chip! till now it's was still idle and drained power. not any more
*Finally i made my kernel STABLE! no more SOD and great battery life!
I have reverted from Linaro 12.06 GCC 4.7.1 builder to Android GCC 4.3 builder
that used to build all ROM and Default kernels!
So no more SOD! and battery is 1.1%/h -15mA :)
*Added more fixes to code from FLUXI kernel, TNX Myfluxi!
*Set 15 CPU freq steps for all profiles and removed settings to change it, there are many code trigers that depend on 15 freq steps, so best to have all for all profiles, then reduce the MAX freq to what needed, (already set)
*if you have added any INIT.D scripts that mess with my settings, REMOVED THEM, then test my kernel,
For some phones to low settings will always kill the phone,
I am asked all people that post INIT.D scripts in this thread, STOP/REMOVE. keep them to your self. thanks.
*Found and removed SOD bug on screen off/on and in deepsleep.
OK for me, need more people to test!
*Ported some stuff from GM SG3 kernel, better video sharpness and some restores for Video driver GPU freq lock on screen ON.
*Tuned all profiles, with min/max cpu on suspend, now we can use 200 to 700, please do not change it for now.
*Lots of new code ported by VOKU from 3.1.Y kernel! see GIT
*Some clean ups, and kernel optimizations FLAGS.
*Removed hotplug and interactive govs, we have lot better govs to use.*fixed small but critical bugs! (reuploaded kernel last at 18:59)
*I have reverted all CODE for CPU Idle and Suspend from Source (GM Thanks again!) now i hope the SOD will be wiped!
*Reduced Kernel size thanks to VOKU new reconfiguration of Kernel flags.
*Added new CPU calibration code form 3.4.y tree.
*Added more fixes for Kernel scheduler.

Fixed all missing config triggers and added more protection from battery gauge reset by extweaks without need.
*New Updates to SLUB scheduler that we use for memory management.
*Added new stuff to extweaks!
Now we have:
bln tab:
SWITCH to turn of BLN!
SWITCH to turn ON led lights on touch! it's use the led time out!
Fixed BLN test button.
cpu tab:
SWITCH to turn on/off wakeup booster and set the boost delay!
*Reverted last USB code update from NOTE, found that driver stuck after long charge and we can get to storage via USB, we have SG3 driver, so to mix them probably bad idea,
*Restored CPU code that needed for SAMMY rom stability to prevent SOD, so i hope it's will be ok now.
*Small fixing and cleaning. see GIT's
*Fixed WIFI wakelocks by removing latest patches, need to work on them first.
*Added CPU patches from GM
*Added Audio Amplifier GAIN for headphones 0DB 1.5DB 3-6DB addon by GM! see extweaks.
*Tweaked all profiles! set the suspend freq to min 700 max 800! as Samsung request! lest stop the SOD! please do not change that settings.
*Added new Patch for WIFI filter found by Entropy512 seems that we had an open packet filter that helped to drain battery with wakelocks!
*Fixed some cortex code, all should be good. and fast!
*Removed EXP ver, need to work on it.
*For now this kernle not include new Power Manager by VOKU, we still testing!
*Fixed Wakeup booster script, now will wake and power the phone for 10 sec on max we can get! the reduce to normal as user set in extweaks! will work only if background process is ON,
*Changed all profiles! boosted GPU freq and voltage for all, after testing with heavy games! now stable! + govs change.
*Cleaned and updated HYPER + ONDEMAND govs to 3.0.Y tree + mods.

*Fixed some bugs in cortex script, removed not used stuff from crypto module.
*Fixed SAMMY boot (reverted some stuff)
*Fixed led_timeout bug in extweaks.
*Fixed zram stats info for roms without BASH, it's temp solution till we can fix the main script.
*Added new tweaks, Negative mod On/Off via checkbox + advanced wakelock mod, will show all wakelocks that was ON and ended! so we can debug, who drained battery! it's OFF, by default, see MISC tab! added by GM! :)
*Updated New USB drivers from NOTE Update 3, need to test all we got (usb devices and external storage via usb)
*Reduced compression via XZ and reduced memory used for it, kernel bigger but little faster on boot.

*Restored luzactive gov and removed tweaks for it on screen on/off now people can use the app for it to control settings.
If someone using apps like SETCPU with his own profiles, please do DISABLE in extweaks cortexbrain tab for CPU-TWEAKS! then your profiles will make difference, if it's enabled, then internal script do the work.
*Improved brightness levels, now more bright, was too dark on min..
*Updated to last released recovery by gokhanmoral!
*Reworked all boot structure to support 4 major branches and still give all that i have to all.
*Small change for kernel name, now it's better to find the last update in recovery!
*Tuned the background control process to wait 10 sec on screen off before do all the system/cpu/voltage/and more changes, just give us time to think if we finished with phone :) before it's shutdown to minimum :)
*Uploaded also in .TAR as promised.*Made lots of code fix and BOOT fix, should be ok now.

*Battery drain reduced due to low cpu use, and allot of stuff.
*Fixed oom_kill_allocating_task set to 0, now it's 1 as recommended.
*Fixed CFS tweaks activation.
*Added CORTEXBRAIN tab in extweaks, now you can control it, best not, but if you like to mess with stuff, then see what it do in initramfs git and change.
*Tuned scary gov should be better now, and removed it from defaul/battery just in case. added abyssplug.
*Switched to more stable compression and optimization level -O3 from Ofast
Should be more stable now. i even see some better benchmarks.
*Improved ROOT Install/Remove in extweaks + check button :)

*Allowed Abyssplug gov to control second CPU on/off
*Ported fix for vibrate for Samsung roms, TNX Gokhanmoral.
Need to test it! so please do.
*FIXED the BATTERY fuel gauge bug! now it's stable as should!
Give it some time to recover from bug to show good drain results.
but it's will stay correct after reboot, (did 10! no problemo!)
*New CPU idle code ported from 3.1.y kernel by VOKU! we now have the most advanced CPU code for SG2 :)
*Lots of changes and restoring and tuning CPU,GOVS,RAM,TWEAKS.
*Tuned data partition to be more resistant to sudden power loose (sod/batt pull and stuff) this is the android default, data=ordered, we had data=writeback, it's faster but less recommended for phones...
So now its safe again.
*Kernel Cleaning Script is build IN! by VOKU no need to run any external clean scripts.
*Small change to BLN, now will obey touch key voltage! only on blink and steady.
*Locked vibrate to min 25% (max 100%) and added code, if less than 25% set 75%, lets see if OK now after long sleep.

added it to all profiles for deepsleep, and to extweaks
*Added more Voltage to CPU, now it's default ICS kernel voltage.
You can now reduce it by using asv group 4 or undervolt by -25 / -50 but test some time if no SOD. or just leave it alone.
*Updated to 3.0.36
*Added TNT to many bugs :laugh:
*Fixed slow wakeups
*Added more +25mv to lower cpu freq ranges to add more stability.
*boosted boot speed.
*Voku helped allot! he added lots of code fixing and updates to filesystem drivers and memory.
*Added new button at extweaks for checking current gps zone config.
*if you like to fix permissions, just push the button at extweaks misc and turn off the screen! fix will begin instantly! if you really need the phone, use it, but best to let it work top 2~3 min, depending on amount of mess and installed apps, it's done my 450 apps in 2 min :)
*we tuned profiles and voku added new stuff to conservative gov! so it's now the most saving battery gov! try it only for deepsleep (screen of gov)
it's slow, but this is what we need! less activity more battery!
*Vibrate should be OK now.
*now if phone is over 50c heat, and you turn off and on the screen. it's will auto drop to 1Ghz and to hotplug gov to cool off..
after temp will drop, and you turn screen on/off all your extweaks settings will be active again! so if was oc to max then you get it back :)
I care about my people :)
*Fixed the vibrate low after some time. + added extweaks interface for it.
*Added touch screen tuning
*Added screen color tuning (extweaks SCREEN tab)
*fixed WIFI driver
*Reduced batt drain
*Added HYPER gov, it's the most powerful gov in my kernel. :)

*Updated to 3.0.35
*Reverted some commits that i think we can ignore for now. too much experimental.
*Added some more code fixes,
*Ported updated Vibrator driver code.
*Restored USB drivers, usb otg/disk-on-key should work.
*Added ZCACHE and CLEANCACHE this will boost I/O performance and help with heavy loads!
*Added massive amount of code fixing and tuning to RAM, CPU, NET.
*Added ability to boot in to DOWNLOAD(odin) mode from ROM->bootloader (credits to gokhanmoral)
*Tuned all profiles,
*Fixed ZRAM / GPS settings in extweaks!
*Added Fix permissions to extweaks MISC
*Added to system tweak to check if you have AD blocker file already, and if you do, then my adblocker will not be installed, if you dont, then you get one :)
*Added Zram turn off! not recommended, it's will shut down the zcache also. (no battery save from it, just little amount of cpu.)
*Added to GPSREGION option to restore your ROM default config! and one for not to change any config. (default!)
But restore will really work after you reinstall your rom, if you already changed it with my previous kernel version, (if not, new kernel users, then you set to go)
*Added lots of WIFI driver fixing! now Ch 13/14 will work as planed, and 5GHZ band will work as should.

It's name is cortexbrain-tune.sh :)
*Added DATA, CACHE, PRELOAD(sec-rom-system) partitions scan for errors and FIX! every boot!
I hope you want clean partition! there is no kernel / rom that will do that for you. :)

*tuned touch screen.
*tuned cpu
*tuned network
*updated recovery from ghokan.
*many new/updated drivers.
for full log see my git for initramfs and kernel.
kernel compressed with zlo the lowest compression for max speed.
so its was to big to fit the boot partition, i had to move the modules out of kernel.
so from version 2.3 you cant update via tar and odin.
so use recovery only.
or update the supplied modules to /system/lib/modules/
if you install via recovery, nothing needs to be done.
in case of emergency use 1.1 kernel in tar, then go to recovery and update to 2.X :)
