Hi,
I've being watching all the developments about the emerging tablets and I must say that all Tegra 250 devices look very interesting, although Toshiba Folio 100 already has PCB pads to add more ram... I am sure that Toshiba will add more 500Mb ram on the next Folio to give a better android 2.3 support.
Anyway, here's my question: how can I, or anyone else, recompile the Linux android kernel for Tegra 250 and place it in the FolioMod, well, I'm asking this because I remembered that these tablets are excellent for one thing that many are forgetting...
To watch digital television from a USB TV pen, well, the device has USB host support, it has Linux to manage the devices attached... What else is need ? Video 4 Linux... This is kernel built-in... So, how can I recompile the kernel to add this and other desktop usual features ? Any cons ?
Cheers.

I am interested in too, if you make any advance let me know; I am really interested in this!!!!
The process is quite straightforward.
Get the kernel source here: http://tegramid.com/wiki/Main_Page
- unzip the source and cd into the source directory
Get the current kernel config from your device:
Code:
adb pull /proc/config.gz
Unpack and rename the config file
Code:
gunzip config.gz
mv config .config
Adjust the config to your needs.
Now you need the an gcc to compile for arm, the easiest way is to checkout the android source repository (read source.android.com for instructions, actually you would only need the prebuilt toolchain)
Now add the compiler to your path environment variable
Code:
export PATH=<android-source-dir>/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/:$PATH
now you can build the kernel using
Code:
make ARCH=arm CROSS_COMPILE=arm-eabi-
Now you need to repack and flash your new kernel to the device.
An excellent article on how to prepare a new boot.img can be found here:
http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
After that simply create an update.zip and flash using recovery.
Note, AFAIK v4l support is already included in the current FolioMod kernel.
WOW
Really thanks, I will try asap!!
Btw according to dmesg output kernel commandline should be:
Code:
[email protected] [email protected] vmalloc=192M video=tegrafb console=ttyS0,115200n8 usbcore.old_scheme_first=1 tegraboot=sdmmc tegrapart=recovery:122000:a00:800,linux:a0e00:1000:800,loader:300:400:800,mbr:700:200:800,system:900:20000:800,cache:20900:80000:800,misc:a0900:400:800,userdata:a1f00:80000:800 boardtype=PR
weeds2000:
So, the kernel is the common Android Tegra 250, have you tried this already ?
I though this could be the thing to do, but I also thought that Toshiba had pulled a fast one by customizing the Android Tegra 250 kernel...
Hum... If this is so, I will buy an Toshiba Folio 100 lol... I hope to add many thing to the kernel... as a programmer I would love to have USB-RS232 adapters too eh eh eh... New horizons then!
I was also thinking, if not this device, the Viewsonic Viewpad 10, that has a BIOS and an Atom, an x86 architecture then, would be much easier to recompile...
It has some modifications ore extra modules.
Compiling the default kernel from the froyo-tegra tree from nvidia failed (not sure what exactly was missing, display simply switched off and it seems there was a kernel panic somewhere)
But yes compiling the kernel from the sources given at the wiki works. I'm running a slightly modified kernel at the moment compiled using the steps given above.
weeds2000:
Its common on embedded devices like most Android devices... The best thing invented is the BIOS lol... Without one, we must hard-code the kernel to map the resources to the specific hardware...
Do you recommend buying a Toshiba Folio 100 ?
Anyway, what modifications have you done (just curious) ?
I would recommend the Folio to someone that can do some modding and is able to flash custom roms to the device.
Before FolioMod the device was pretty much useless to me, but with the modifications done by dexter and the rest of us, it turned out to be a pretty good device.
However I would not order it blind because of the display. Compared to, for example the Galaxy Tab, you can clearly see why the device is that cheap. Viewing angle is really not good on this, so you may want to take a look at a store or something if this bother you or not (it's OK for me though).
Kernel modifications where
- mouse driver (to fix the bug introduced by the rotation fix, without success up to now)
- playing around with the kernel hacking options to get some performance. turning them off however prevent the wifi module to load
- adding utf8 NLS support to the kernel (also this is the default, as this is required to mount NTFS partitions with utf8 support, otherwise some files where missing or have bad encoding and could not be opend by mediaplayer/reader/whatever.
When you do the make config, in the kernel options menu do you recall seeing the video4linux ?
I'm guessing that the tablet only needs that included on the built kernel to fire up TV watching programs, the idea is to load a USB digital TV device and run any Linux TV programs. Not going to MythTV because it might have too many dependencies... and not all libraries are available to ARM...
The view angle doesn't bother me that much, as long as the screen image is flawless eh eh eh, its a media tablet, so, it should be anyway...
One more thing, that key combination to flash the device comes already from factory right? I recall seeing a similar combination on the NVidea Tegra 250 development board. Or does it need the Dexter flasher too ?
I'm new to tablets as you can see lol and I'm seeing lots of tasty looking tablets... I want one that I can use for hack in my (I wish) free time, I guess its just like most people here lol.
The Viewpad 10 is about the same price, has x86 (single core tho) and more 500MB ram and ... a BIOS ... But has pros and cons... damn why can't we have it all... I guess I will try to see some in my hands first. iPad looks great, but lacks connectivity and Apple wants money for a developer membership lol... Android is incredibly but the vendors are crooks that embed the kernel with the hardware instead of adding a BIOS... Windows Mobile is... to limited and simple to use, no console... bah... Is there was one for free I would pick that one, but they all have similar prices... The reviews show that all have pros and cons... oh well...
OK getting mythTV on the device is quite an impressive task.
As not even the c-library is the default glibc known from your desktop PC and may miss a few things here and there. (learned that when trying to port libfuse and ntfs-3g)

Whoa, CONFIG_MEDIA_TUNER and CONFIG_MEDIA_TUNER_SIMPLE on from default ?! Also V4L ?!?! what is going on here?! Is Toshiba thinking about making an docking station with a TV Tuner in it and a custom software to watch TV ?!
Edit: I was dreaming awake... I didn't noticed that you were writing about FolioMod kernel... But it would be fun if they did had added these features...
I used mythTV as an example LOL It has too much dependencies... I could try to get all the dependencies for ARM... or compile some for ARM... but it would take lots of time... TVTime looks better for Android, I'm off to see a real Folio 100 on my hands, I have lots of doubts LOL...
It also seems that radio was not forgotten, CONFIG_RADIO_ADAPTERS on... also a possible digital audio broadcast support... hum...
It could be fun if I or someone managed to get a TV Tunner on Folio, TV on camping, TV on the bed, TV everywhere !
The Android kernel seems to have fewer drivers tho... a pity...
Was anyone successful on compiling tegra 250 image for flashing board
Howto - creating a boot.img with new kernel
Note: I wrote a small guide how to repack boot.img when you have your new compiled kernel (based on http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images but modified for folio). I also included modified perl scripts and binary files needed under linux (ubuntu 10.10) for that (no need to compile tools from sdk). So that swapping a new zImage kernel instead of an old one is a question of seconds
See - Howto - unpack,edit,repack boot.img: http://forum.xda-developers.com/showthread.php?t=915808
hi guys i dont know if this is related to kernel but i would like to get the android policy jar. do you know how to do it?
thanks!
This is quite interesting topic you are discussing here.....
Can you pls gather the information abt the kernel compilation as well as image assembly so others can experiment too ?
What are chances to brick the device during tests ?
Being a linux user for some time I would be very happy to have something like
- either a custom kernel for android for playing
- or linux distribution to run on the device (as Archos 5 IT have dual boot with Linux for example)
perhaps we can gather up to produce something like it for our device ????
thanks
is possible try compiling kernel 2.6.35 for folio?? anyone has tried?

Dorimanx Kernel for SGII-I9100
Supporting 5 ROM Platforms!
My kernel was based on SiyahKernel 4.0 long time ago in other realty,
Kernel Tree is 3.12.rc6-R101, + Samsung JB updates + my tweaks and lots of tuning!
Thank you Gokhanmoral for your great work in the past!
Warning!!!
Do not install this kernel on any Android version lower than 4.1.Y
Do a Nandroid Backup of your ROM before first try it! just in case
Constant OC will drain more battery! use low speeds on screen off! min 200/100 max 800
CPU will shutdown in case of over-volt or under-volt so be careful
I'm no responsible for any hardware damage or system corruption that can happen after using this kernel,
you are using this kernel from your own will and accept any responsibility by using it.
If you install this kernel your warranty will be void!
Of course you can be relaxed, I'm trying every release on my phone several hours before of release it so,
if something wrong, i will get the damage first, you get a tested and tuned working kernel...

Kernel 5.84
*VOKU and me, we restored function that check DATA + CACHE file system before boot, for errors and damaged blocks and more.
it's can be requested for one time run by user via extweaks misc tab.
DO NAN DROID BACKUP VIA RECOVERY BEFORE ANY ATTEMPT TO USE IT! (if your phone will not boot, and you don't have backup, don't blame me for that)
If your data has allot of corrupted files. then first boot with this kernel will take longer! do not panic. let it work.
no more than 10MIN, if still no boot, then you need to restore your nand backup and never use this function!
your hardware is not ready for DATA partition clean up. forget it.
you will get new file /log-data and /log-cache
after boot you can check if you had any errors in data or cache.
To activate just "push the ATOMIC button " or push again to ABORT!
function will work after reboot, and never again, till requested by user.
If you do nan droid backup and then restore it, you restore all the errors and junk with it. (just for the info)
Goals for next builds:
Debug and find more code errors! (always something new)
Add cool features and tweaks
Extend battery life.
Boost performance.
« Installation
Download the file
Place it on your SD card
Reboot into recovery
Flash the file
Reboot
In case of a new installation on a non rooted or non recovery device:
You can Download ODIN 3.04 attached to page.
Reboot to Download mode (Hold Power + Home + Vol down, then vol up when you see the download menu)
Connect USB, wait until the drivers be installed
Install kernel via ODIN, choosing the option PDA, search for the file that you downloaded and push start
If all going fine the phone will reboot and you done

GESTURES!
Here you can download the app to set the gesture_set.sh script to make your own gestures.
*Added gestures script that connected with cortex and can be managed by user and system in harmony!
The script is located at /data/gestures_set.sh do not move it, if you have already any gestures scripts in init.d delete them and move your custom stuff to this script.
It will work with the screen on, and be shut on screen off, to get rid of one more loop that wait forever, we dont need it on screen off! So i give you 5 preconfigured gestures! max supported is 10! max finger touches supported also 10.
Script will be copied to data if not exist on boot, if exist then, nothing. You can shut this function in STweaks or restore to default gestures if you mess with it
On restore you will get backup of your current running file at /data/gestures_set.sh.bkp + gesture_set.sh.sec just in case.
PICK FOUND IN GOOGLE! It's not me
I am here for you so, ask, debug and comment!
Help me to make this kernel as good as possible!

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..
Code:
[email protected]:/ # 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:
Code:

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
Code:
*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.
*Tuned all profiles, now sleep gov is pegasuq for all!
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.
*Lots of new stuff ported by voku for WIFI driver, so test it as much as you can.
*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.
*Small new fix to WIFI driver.
*Added interactive to govs, updated to max by myfluxi
*Added code correction for suspend freq + max freq for performance gov.
*Tuned touch screen wakeup and responce, very smooth now.

*New fix to WIFI driver.
*Improved I/O latency
*Improved disk write to USB storage
*Improved screen wakeup
*Improved screen off state battery saver. (cortex)
*Lots of code fix and porting as always
*Reduced logs to dmesg and logcat, less chat, maybe less drain..
*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.
*VOKU ported new code for RAM, CPU, Power manager from 3.1.Y good work!

*Lots of tuning and code fix, see GIT, it's too much for change log page*Massive PORT and adapt from 3.1.Y kernel by VOKU!
New code for: CPU, RAM, FS, Kernel operations and lots more! see GIT!
Now cpu used 1~10% on 100Mhz! and was like 25~35% so more battery save and more performance.
*Fixed Voltage for cpu reset on screen on/off
*Added new LOGO :) by Crazy-silver
*Arranged CPU govs by performance for awake, and by power save in deepsleep
See Extweaks CPU tab.
*Fixed battery reset on recovery.
*Added new Tweaks to CFS scheduler in CPU tab. tune it only if you know what is it and what it's set.

*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.

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.
*More code updates from mainstream 3.0.y (some stuff was lost, so now i have my own mainstream kernel to update from)
*Tuned MAX freq for standby to 700Mhz
*Fixed UV reset after screen on/off
*Small config changes in INIT scripts / profiles.
*Added scary gov :) it's SLOW gov, good for battery save and will be used for deepsleep, also tuned it to wakeup fast!
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 :)

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 :)

ZRAM (aka CompCache aka RAMZSwap)
ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 3.0.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible.

# ==============================================================
# Logic Explanations
#
# This script will manipulate all the system / cpu / battery behavior
# Based on chosen EXTWEAKS profile+tweaks and based on SCREEN ON/OFF state.
#
# When User select battery/default profile all tuning will be toward battery save!
# But user loose performance -20% and get more stable system and more battery left.
#
# When user select performance profile, tuning will be to max performance on screen ON!
# When screen OFF all tuning switched to max power saving! as with battery profile,
# So user gets max performance and max battery save but only on screen OFF.
#
# This script change governors and tuning for them on the fly!
# Also switch on/off hotplug CPU core based on screen on/off.
# This script reset battery stats when battery is 100% charged.
# This script tune Network and System VM settings and ROM settings tuning.
# This script changing default MOUNT options and I/O tweaks for all flash disks and ZRAM.

# Explanations
# ==============================================================
#
# oom_kill_allocating_task: If this is set to zero, the OOM killer will scan through the entire tasklist and select a task based on heuristics to kill.
#
# This normally selects a rogue memory-hogging task that frees up a large amount of memory when killed.
# If this is set to non-zero, the OOM killer simply kills the task that triggered the out-of-memory condition.
# This avoids the expensive tasklist scan.
#
# echo XXX > /proc/sys/vm/oom_kill_allocating_task;
# dirty_expire_centisecs: This tunable is used to define when dirty data is old enough to be eligible for writeout by the pdflush daemons.
#
# It is expressed in 100'ths of a second. Data which has been dirty in memory for longer than this interval will be written
# out next time a pdflush daemon wakes up.
#
# echo XXX > /proc/sys/vm/dirty_expire_centisecs;
# dirty_writeback_centisecs: The pdflush writeback daemons will periodically wake up and write "old" data out to disk.
#
# This tunable expresses the interval between those wakeups, in 100'ths of a second.
# Setting this to zero disables periodic writeback altogether.
#
# echo XXX > /proc/sys/vm/dirty_writeback_centisecs;
# drop_caches: Writing to this will cause the kernel to drop clean caches, dentries and inodes from memory, causing that memory to become free.
#
# To free pagecache:
# echo 1 > /proc/sys/vm/drop_caches
#
# To free dentries and inodes:
# echo 2 > /proc/sys/vm/drop_caches
#
# To free pagecache, dentries and inodes:
# echo 3 > /proc/sys/vm/drop_caches
# page-cluster: page-cluster controls the number of pages which are written to swap in a single attempt. The swap I/O size.
#
# It is a logarithmic value - setting it to zero means "1 page", setting it to 1 means "2 pages", setting it to 2 means "4 pages", etc.
# The default value is three (eight pages at a time). There may be some small benefits in tuning this to
# a different value if your workload is swap-intensive. (default 3)
#
# echo XXX > /proc/sys/vm/page-cluster;
# laptop_mode: laptop_mode is a knob that controls "laptop mode". When the knob is set, any physical disk I/O
#
# (that might have caused the hard disk to spin up, see /proc/sys/vm/block_dump) causes Linux to flush all dirty blocks.
# The result of this is that after a disk has spun down, it will not be spun up anymore to write dirty blocks,
# because those blocks had already been written immediately after the most recent read operation.
# The value of the laptop_mode knob determines the time between the occurrence of disk I/O and when the flush is triggered.
# A sensible value for the knob is 5 seconds. Setting the knob to 0 disables laptop mode.
#
# echo XXX > /proc/sys/vm/laptop_mode;
# rr_interval: rr_interval or "round robin interval". This is the maximum time two SCHED_OTHER (or SCHED_NORMAL, the common scheduling policy)
#
# tasks of the same nice level will be running for, or looking at it the other way around, the longest duration two tasks
# of the same nice level will be delayed for. When a task requests cpu time, it is given a quota (time_slice) equal to the
# rr_interval and a virtual deadline, while increasing it will improve throughput, but at the cost of worsening latencies.

#
# The default value is 60. If you want kernel to swap out more process memory and thus cache more file contents increase the value.
# Otherwise, if you would like kernel to swap less decrease it. A value of 0 means "do not swap unless out of free RAM",

# overcommit_memory: Controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
#
# 0 - Heuristic overcommit handling.
# Obvious overcommits of address space are refused. Used for a typical system.
# It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage.
# root is allowed to allocate slighly more memory in this mode. This is the default.
# 1 - Always overcommit.
# Appropriate for some scientific applications.
# 2 - Don't overcommit.
# The total address space commit for the system is not permitted to exceed swap plus a
# configurable percentage (default is 50) of physical RAM. Depending on the percentage you use,
# in most situations this means a process will not be killed while attempting to use already-allocated memory but
# will receive errors on memory allocation as appropriate.
# overcommit_ratio: Percentage of physical memory size to include in overcommit calculations.
#
# Memory allocation limit = swapspace + physmem * (overcommit_ratio / 100)
#
# swapspace = total size of all swap areas
# physmem = size of physical memory in system
# vfs_cache_pressure: Controls the tendency of the kernel to reclaim the memory which is used for caching of directory and inode objects.
#
# At the default value of vfs_cache_pressure = 100 the kernel will attempt to reclaim dentries and inodes at a "fair" rate with respect
# to pagecache and swapcache reclaim. Decreasing vfs_cache_pressure causes the kernel to prefer to retain dentry and inode caches.

#
# fifo_batch: Controls the maximum number of requests per batch.
#
# This parameter tunes the balance between per-request latency and aggregate
# throughput. When low latency is the primary concern, smaller is better (where
# a value of 1 yields first-come first-served behaviour). Increasing fifo_batch
# generally improves throughput, at the cost of latency variation.
# back_seek_max: This parameter, given in Kbytes, sets the maximum גdistanceג
#
# By default, this parameter is set to 16 MBytes.
# This distance is the amount of space from the current head location to the sectors that are backward in terms of distance.
# This idea comes from the Anticipatory Scheduler (AS) about anticipating the location of the next request.
# This parameter allows the scheduler to anticipate requests in the גbackwardג
nextג
# back_seek_penalty: This parameter is used to compute the cost of backward seeking.
#
# If the backward distance of a request is just (1/back_seek_penalty) from a גfrontג
# the seeking cost of the two requests is considered equivalent and the scheduler will not bias toward one or the other
# (otherwise the scheduler will bias the selection to גfront direction requests).
# Recall, the CFQ has the concept of elevators so it will try to seek in the current direction as much as possible to avoid the latency associated with a seek.
# This parameters defaults to 2 so if the distance is only 1/2 of the forward distance, CFQ will consider the backward request to be close enough
# to the current head location to be גcloseג
# fifo_expire_async: This particular parameter is used to set the timeout of asynchronous requests.
#
# Recall that CFQ maintains a fifo (first-in, first-out) list to manage timeout requests.
# In addition, CFQ doesnגt check the expired requests from the fifo queue after one timeout is dispatched (i.e. there is a delay in processing the expired request).
# The default value for this parameter is 250 ms. A smaller value means the timeout is considered much more quickly than a larger value.
# fifo_expire_sync: This parameter is the same as fifo_expire_async but for synchronous requests.
#
# The default value for this parameter is 125 ms.
# If you want to favor synchronous request over asynchronous requests, then this value should be decreased relative to fifo_expire_asynchronous.
# slice_sync: Remember that when a queue is selected for execution, the queues IO requests are only executed for a certain amount of time (the time_slice) before switching to another queue.
#
# This parameter is used to calculate the time slice of the synchronous queue.
# The default value for this parameter is 100 ms, but this isnגt the true time slice.
# Rather the time slice is computed from the following: time_slice = slice_sync + (slice_sync / 5 * 4 ג io_priority)).
# If you want the time slice for the synchronous queue to be longer (perhaps you have more synchronous operations), then increase the value of slice_sync.
# slice_async: This parameter is the same as slice_sync but for the asynchronous queue.
#
# The default is 40 ms. Notice that synchronous operations are preferred over asynchronous operations.
# slice_asyn_rq: This parameter is used to limit the dispatching of asynchronous requests to the device request-queue in queueגs slice time.
#
# This limits the number of asynchronous requests are executed (dispatched).
# The maximum number of requests that are allowed to be dispatched also depends upon the io priority.
# The equations for computing the maximum number of requests is, max_nr_requests = 2 * (slice_async_rq + slice_async_rq * (7 ג io_priority)). The default for slice_async_rq is 2.
# slice_idle: This parameter is the idle time for the synchronous queue only.
#
# In a queueגs time slice (the amount of time operations can be dispatched), when there are no requests in the synchronous queue CFQ will not switch to another queue
# but will sit idle to wait for the process creating more requests. If there are no new requests submitted within the idle time, then the queue will expire.
# The default value for this parameter is 8 ms. This parameters can control the amount of time the schedulers waits for synchronous requests.
# This can be important since synchronous requests tend to block execution of the process until the operation is completed. Consequently,
# the IO scheduler looks for synchronous requests within the idle window of time that might come from a streaming video application or something that needs synchronous operations.
# quantum: This parameter controls the number of dispatched requests to the device queue, request-device (i.e. the number of requests that are executed or at least sent for execution).
#
# In a queueגs time slice, a request will not be dispatched if the number of requests in the device request-device exceeds this parameter.
# For the asynchronous queue, dispatching the requests is also restricted by the parameter slice_async_rq. The default for this parameter is 4.
# ===============
#
# BFQ-Settings
#
# ===============
# timeout_sync, timeout_async: The maximum amount of disk time that can be given to a task once it has been selected for service, respectively for synchronous and asynchronous queues.
#
# It allows the user to specify a maximum slice length to put an upper bound to the latencies imposed by the scheduler.
# max_budget: The maximum amount of service, measured in disk sectors, that can be provided to a queue once it is selected (of course within the limits of the above timeouts).
#
# According to what we said in the description of the algoritm, larger values increase the throughput for the single tasks and for the system,
# in proportion to the percentage of sequential requests issued. The price is increasing the maximum latency a request may incur in.
# The default value is 0, which enables auto-tuning: BFQ tries to estimate it as the maximum number of sectors that can be served during timeout_sync.
# max_budget_async_rq: In addition to the max_budget, limit, async queues are served for a maximum number of requests, after that a new queue is selected.
# low_latency: If equal to 1 (default value), interactive and soft real-time applications are privileged and experience a lower latency.

TapaTalk Gnex Galaxy Sii
so far everything work perfect-it's mega speed kernel,no UV,no set cpu and bench is 4813 on quadrand
fantastic
thanks
The king of Kernels is here.
Needless to say I'm another old HD2 user, and i regard you as one of the main Developers responsible for the HD2's longevity.
The S2 community is in for a treat.

Downloadinng.....aweesoome....1st true rolopped for XSP c5302....gr8 job maan
:good::good::good:
Thanks alot for the ROM.. I will wait untill some one install this ROM in C5303.. Because day before yesterday i flashed Indian Stock FTF ( 2.254 ) in ma SP and the result is my sim card wont work. No signal.. Its keep asking me to insert ur Sim...
After that flashed C5303 firmware and deodexed it... Now ok.. So i will wait...
And we all are waiting for the Full Port of The Honami Framework... If u can do that means this ROM will call a 100% Honamialaztion....

Script tweaks description
Special Thanks to Jeeko bro for the PurePerformances™X | Golden Edition
One of the best scripts ever made on XDA
FEATURES:
Code:
- Android performances improved at 360°
- Radically improved management ram on android (Lags...adios!)
- Script lightweight and revised to be adapted to this engine
- Improves a lot the graphics: of course Pure Graphic™HD, Pure Dithering Plus™ and... AOSPA 3.60 system tweaks
- Scan multimedia time drastically reduced
- Network Improvements, 3G experience even in 2G modality
- All SQlite database optimized
- Enable hardware features turned off by default for a better experience on entry level devices
- Greatly increases the score AnTuTu: Try it to believe it!!
- Reduces the startup time of Android
- A version for stock rom and one for CM, to squeeze any roms!
- Allows you to play ported games without lags
- Cleans the system every 24 hours, thecache every week and the Dalvik every month (cronos easter egg)
- Automatically Zipalign on each boot (sensitive to the user)[/COLOR]
Battery:
Code:
- Drastically decreased the drainage of battery
- Check the activities that consume too much battery stop them with PureWakelocks™
- When the phone is charging reduces system services for faster charging
- The battery is calibrated on every boot
- Disable animation of the system when the battery is nearly exhausted
- Improvements in build.prop as regards the part of consumption
Graphics, Screen, Images
Code:
- Enables a non-aggressive dithering to save CPU
- When you lock the device, the engine makes sure that the GPU is turned off
- Enables deep sleepalso in the bugged rom
- Parts of bravia engine
- parts of CrossBreeder (credits to dev)
- parts of Adrenaline Engine (credits to dev)
- PureGraphics HD
- V6 supercharger
- Generates video entropy (like seeder)
CPU, Governors, I/O Schedulers
Code:
- Slightly improves the scaling of the frequencies (for better results you need a good kernel)
- Lightens the load on the CPU switching the workload to GPU rendering
- Enable the swap partition in Android (experimental)
Init.D Tweaks description
Code:
1. strict minfree handler tweak
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree

echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
Code:
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier =0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /cache
Code:
7. Flags blocks as non-rotational and increases cache size
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
Code:
8. microSD card speed tweak
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
Code:
9. Defrags database files
for i in
`find /data -iname "*.db"`
do
sqlite3 $i 'VACUUM;';
done
Code:
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` * 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
Code:
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Auto-zipalign on boot
(needs zipalign bin)
Code:
12. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
Code:
13. Disable normalize sleeper
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features[/COLOR][/HIDE]
Code:
+/system/etc/init.d/ scripts :

Installation Instructions / F.A.Q's
Installation Instructions :
Fresh installation "Recommended to flash this ROM on a newly flashed ftf" :
Locked Bootloader
- Flash this ROM "ONLY" on Sony's latest firmware 4.1.2, 12.0.A.2.254 (Do not expect much help from me if you flash it on any other firmware and get messed up)
- Root using DoomLord's method http://forum.xda-developers.com/showthread.php?t=2405933
- Install CWM for Locked Bootloaders http://forum.xda-developers.com/showthread.php?t=2352920
- Reboot in recovery/CWM > Wipe Data/Factory Reset > Mounts & Storage > Format System > Mount System
- Flash the rom and reboot (reboot may take some time, don't panic)
Unlocked Bootloader
- Flash this ROM "ONLY" on Sony's latest firmware 4.1.2, 12.0.A.2.254 (Do not expect much help from me if you flash it on any other firmware and get messed up)
- fastboot flashboot @alivanov79's Dual Recovery (CWM/TWRP) with autoroot (TWRP) recommended to flash this ROM for unlocked bootloaders : http://forum.xda-developers.com/showthread.php?t=2404452
- If you don't know much about fastboot and flashing kernels root using DooMLord's method : http://forum.xda-developers.com/showthread.php?t=2405933
- Install CWM for Locked/Unlocked Bootloaders http://forum.xda-developers.com/show....php?t=2352920
- Reboot in recovery/CWM/TWRP > Wipe Data/Factory Reset
- Flash the ROM and reboot (reboot may take some time, don't panic)
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
F.A.Q's
Q1 - Is this ROM for locked bootloader or unlocked bootloader?
A1 - It's for both, just follow the Installation Instructions thoroughly.
Q2 - Can I install this ROM on C5303/06
A2 - You can install this ROM on all SP models, just test and let me know if LTE is working for C5303/06
Q3 - Why in Installation Instructions it's mentioned "Flash this ROM "ONLY" on Sony's latest firmware 4.1.2, 12.0.A.2.254 Firmware"
A3 - Because this ROM is completely based on 12.0.A.2.254, and I have tried installing this ROM on different firmwares and it gives lots of error, so "DO NOT" flash this ROM on any firmware other than 12.0.A.2.254
Q4 - I see too many tweaks in the ROM of init.d and other script, will it not make the device unstable?
A4 - No, All those tweaks are to optimize the Android, so none of the tweaks will make it unstable.
Notes / Donations / Change-Log's
NOTES :
- Fully Tested on Locked and Unlocked Bootloaders.
- This ROM is for C5302, you can use it on C5303 or C5306, but I am not sure if 4G will work. (test and let me know)
- I am not responsible for any damages caused to your device.
- If you appreciate my hard work hit thanks and rate or even donate.

Few extra stuff to come, main is framework, it's a bit messy, coz framework gives bootloops after decompiling it once wether edit or just recompile, but I got some great devs helping in this, so framework shall be the biggest feature in this ROM

Are you porting the full Honami framework or just theming it?
If you are porting the full framework (with all the new stuff and infinite small apps) directly from the Honami ROMs (of Xperia Z or Z1), then I can't help you.
Refer to this if you have bootloops even with just recompiling: http://forum.xda-developers.com/showthread.php?t=2321207
Also, you have to install SemcUxpGenericRes.apk first before decompiling framework-res.apk by using
Code:
apktool if SemcUxpGenericRes.apk
By the way, use the framework-res.apk from here: http://forum.xda-developers.com/showthread.php?t=2405874
It did not give me bootloops while recompiling.
Hope this helps

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).
2.7
many various commits from Linux 3.3 (thanks @faux123)
improved hotplugging mechanism
updated RCU system
kernel scheduler
memory management
etc...
LiveOPP:
recalibrate varm and vbbx on boot (better stability)
added interface to OC some clocks that depends on PLLDDR
reimplemented sweep2wake and doubletap2wake (thanks @Meticulus)
enabled UKSM (thanks @cocafe)
- better RAM performance with tiny cost CPU. Boot time will be increased by 3 sec, it's ok.
uploaded kernel for s6d.
R2.6
ABB-charger:
reverted most of changes. It's only uses custom voltage table, termination current 150 mA and some other tweaks, provided by ace2nutzer.
added tweakable interfaces for termination current(better battery lifetime).
LiveOPP:
added most ape_25_opp switch interface
added steps 85, 350, 450 MHz.
ddrpll interface renamed to pllddr ;D
added input boost support for most of governors (thanks to zwliew for original patch)
R2.5
- only one kernel version for all ROMs/Filesystems/codina(p), please note that installation method is different from usual installation
- Switch to single platform RTC driver - AB500 (finally fixed all problems with clock freeze issue) [golden-guy]
- update LiveOPP from CoCore
- reworked and added DDRPLL boost [WIP]
R2.4
completely rewritten screenoff limits driver
added steps 30, 125, 150, 175 MHz, increased voltage on various steps for stability
enabled SELinux again
various fixes in FAT filesystem
re-added exFat support
re-added ZenX
abb charger fix v2 [ace2nutzer]
zRam script moved to init.d (to be able to change zRam size) on CM11
new package installation script, with little changes by me (thanks to borkins for help with this)
R2.3.2
improved battery live (full credit to ace2nutzer)
reduced liveopp table (too hard to search stable/optimal voltage)
Reverted all commits from tuna kernel (these changes are tested not well, may cause instability)
temporarily disabled SELinux
R2.2
LiveOPP 2.2:
no longer use setting ARM OPP (this previously caused lags)
simple algorithm for setting clock and voltages
use only pll, external clock no longer used
use only 1 varm selection

UV 100-400 MHz steps to 0x12-0x14 (lower power consumption)
added state APE_25_OPP, used only with screen off(originally introduced by mkaluza, adapted for codina by me)
allowed change APE_OPP and DDR_OPP from LiveOPP
changed step 1228 MHz -> 1248 MHz (may cause reboots, need to find out optimal voltage)
Mali improvements by mkaluza

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.
(Tweak app)

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");

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
