[MOD]Auto Compcache & backup Swap for CM.

Many people having issues getting compcache/swap working, so here we go.
Replace the content of your userinit.sh with this code. This code was created by uwonsom and modified by yours truely and lastely by Alapapa. to see the original work click Here.
I've also attached the file ready for you to throw directly into /system/sd.
{from original post}
The current setting enables compcache with backing_swap (a physical partition). It can also be tested with linux-swap only--just comment out lines beginning with insmod, mknod, and swapon /dev/ramzswap0. Then uncomment swapon /dev/block/mmcblk0p3.
If you wish to test it out only with compcache, comment out the insmod line with backing_swap and uncomment the insmod line with disksize_kb.
{/from original post}
Code:
#!/system/bin/sh
##adb push userinit.sh /system/sd/
uname_r=`uname -r`
moddir=`find /system/modules -type d -name $uname_r`
insmod=/system/bin/insmod
$insmod $moddir/compcache/xvmalloc.ko;
#$insmod $moddir/compcache/ramzswap.ko disksize_kb=32768;
$insmod $moddir/compcache/ramzswap.ko backing_swap=/dev/block/mmcblk0p3;
mknod /dev/ramzswap0 b 253 0;
echo 20 > /proc/sys/vm/swappiness;

echo 528000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq;
Edit: Thank Alapapa for the new code, will now work with all versions of CM 3.6.7 and higher!

Thanks! But it's not going to work if Cyanogen changes the kernal again.
2.6.29.6 is current... but probably not for long.

does the attached userinit come with those changes already or do u have to modd theose changes over to it

here's the code that will work if kernel version changes:
Code:
#!/system/bin/sh
##adb push userinit.sh /system/sd/
uname_r=`uname -r`
moddir=`find /system/modules -type d -name $uname_r`
insmod=/system/bin/insmod
$insmod $moddir/compcache/xvmalloc.ko;
#$insmod $moddir/compcache/ramzswap.ko disksize_kb=32768;
$insmod $moddir/compcache/ramzswap.ko backing_swap=/dev/block/mmcblk0p3;
mknod /dev/ramzswap0 b 253 0;
echo 20 > /proc/sys/vm/swappiness;
# Experimental settings
echo 1 > /proc/sys/vm/page-cluster; # default: 3 Changes Page clustering from 8 to 2.
echo 5 > /proc/sys/vm/laptop_mode; # default: 0 Helps keep SSD from getting worn.
echo 5000 > /proc/sys/vm/dirty_expire_centisecs; # default: 3000
echo 800 > /proc/sys/vm/dirty_writeback_centisecs; # default: 500
echo 10 > /proc/sys/vm/dirty_background_ratio; # default: 5
echo 16 > /proc/sys/vm/dirty_ratio; # default: 10
#
swapon /dev/ramzswap0;
#swapon /dev/block/mmcblk0p3;
#Over Clock CPU when in use, puts at lower freq when idol. # if you don't want it.
echo 128000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq;
echo 528000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq;

thanks Alapapa, changed the script uptop and the one attached to your modifed script.

De nada...I got the kernel version magic from some thread on here at some point.
Cheers!

Any reason for setting page cluster to 1 instead of 0, as I think i saw earlier in the thread being recommended? Have you had better performance w/ setting it to 1? Thanks

I personally haven't screwed around with the paging. you may get better, you may not.

You could do away with this line since the CPU already scales to 528MHz:
Code:
echo 528000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq;

Add the following.:
Code:
echo 200 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/powersave_bias; # default: 0
#echo 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate; # For build <=3.9.1
"The powersave_bias parameter modifies the behavior of the ondemand governor to save more power by reducing the target frequency by a specified percentage. By default, (powersave_bias = 0), the ondemand governor selects the minimum processor frequency that can still complete a workload with minimal idle time. Doing so should result in the highest performance to power efficiency ratio. In some cases, you might prefer a greater emphasis on power efficiency than performance. In this case, set the powersave_bias parameter to a value between 1 and 1000 to reduce the target frequency by one-thousandth of that value. For example, set powersave_bias to 100 for a one-tenth reduction in target frequency. In this case, if the governor chooses a target frequency of 2 GHz (with powersave_bias = 100), the governor instead will request 1.8GHz – a one-tenth reduction. If 1.8 GHz is an exact match with an available hardware frequency (listed in the scaling_available_freq parameter), the processor is set to this frequency. If 1.8 GHz is not available, the processor fluctuates between the closest available upper and lower frequencies for an average frequency of 1.8 GHz."
If you notice lag, I would set it to 150; 100 was not much of a benefit. 250 will give you longer battery life for sure, but anything over that could result in major lag.

I pushed the file to /system/sd
I run cmd #free and there's 0 under swap
I run cmd #cat /proc/ramzswap and get an error
When I look in /system/sd the userinit.sh file is in lost+found... Did I do something wrong?

Yeah same here (except my userinit.sh is not being moved to lost+found).
I ensured the permissions were fine... what am I doing wrong?

Did you execute it or reboot? Just putting it there does nothing by itself.
In a shell, just do /system/sd/userinit.sh
What happens?

Yeah I thought Cyanogen's roms would auto-run userinit.sh?
Anyway trying to manually run it just throws up errors.

Is this correct for a linux swap partition?
I was unsure about lines
$insmod $moddir/compcache/xvmalloc.ko;
$insmod $moddir/compcache/ramzswap.ko
Does the $ mean i do not comment them out?
Code:

Also i am stuck at work, so not ADB for me (don't want to install drivers on work pc)
Can i do this with userinit.sh on root of card
Code:
Code:
# su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cp /sdcard/userinit.sh /system/sd/userinit.sh
# chmod 755 /system/sd/userinit.sh

Yes, and you should also comment out this backing_swap=/dev/block/mmcblk0p3;

You have to execute it somehow. Cyanogen's roms do it on boot, that's why I said "execute OR reboot".
If you can't run it manually, it's probably not working on boot either. What errors is it throwing up?

It's fine the way it is. But if you look at this thread, some of my experimental settings have been implemented into a new userinit.sh script with a user.conf file that makes things so easy where you wont ever have to touch the userinit.sh script.
Now, I have edited this new script. I corrected a line that could potentially pose a problem for people using a different kernel. I also added a few more options to the script that can be set in the user.conf file. I will post it on that thread in a few minutes.

Sorry I missed the reboot comment.
I just don't understand it. It will not run the userinit.sh. It is saying it can't find it. If I try to run it with the wrong permissions it gives me a "Permission denied" but as soon as I chmod it too 755 it suddenly can't find the file...
I accidentally pasted the whole userinit.sh text the shell and it started working, so I have no idea whats wrong with this file. None what so ever.

ICS Transition Animations
A simple tutorial to get ICS transition animations on any ROM
Full credits to Capez only
Download APK Multi Tool (previously known as APK manager) from here
2) Extract with WinRAR, from the ROM you want to modify, the file framework-res.apk, that you can find in the directory \System\framework\.
3) Go to the apk manager folder and place the framework-res.apk file in the folder "place-apk-here-for-modding".
4) In the apk manager folder, double click on the file "Script". A cmd window will open.
5) Where it says "Please make your decision", write "22" (Set current project) and enter. Then enter "1" (to choose the first apk) and enter. Then enter "9" (Decompile apk) and enter.
The script will decompile the framework-res.apk.
6) Now go to your apk manager folder, go to Projects\framework-res.apk\res\anim\.
In this folder there are the animations of your rom. They consist in some .xml files decompiled.
7) Download this:
http://www.mediafire.com/?1qjwtotg1r8umm1
8) Copy the files from the folder "anims" of the zip downloaded into the anim folder and you are asked to replace the files; choose yes. Then copy also the files from the folder "other_files" to the anim folder.
9) Now go to your apk manager folder, go to Projects\framework-res.apk\res\values\. Edit the file integers.xml and put these two lines under the line of "shortAnimTime":
<integer name="config_activityShortDur">150</integer>
<integer name="config_activityDefaultDur">220</integer>
Save.
10) Return to Script. Enter "11" (Compile apk) and enter.
The script will rebuild the framework-res.apk.
11) You are asked if this is a system application. Enter "y" and enter. Then a second question appears. Enter newly "y".
12) Then after it processes, Don't press anything & DON'T CLOSE THIS WINDOW!!! A new folder "keep" is created in the apk manager folder. Go inside it and delete the file "resources.arsc". Now go inside keep\res\anim\ and delete every file with the same name as every file of the "anims" folder of the zip downloaded.
Then return to Script and press enter. It processes, then if everything went ok, in the folder "place-apk-here-for-modding" a file "unsignedframework-res.apk" is created. Copy it outside and rename it "framework_res.apk".
13) Now you can create a flashable zip or you can simply push it to your system (but you have to sign the apk).
CONGRATRULATIONS!!! YOU ARE DONE!!!

Swapping out PNG's in .apk
Full credits to itiskonrad
***Swapping out PNG's***
Okay, so say you have an icon or an image in your phone that you just don't like and would like to swap out with something (or swap out with nothing, so you can't see it at all). Here is what you'll need:
7zip for your computer
Root explorer for your phone
Some kind of image editor. I'm partial towards Paint.net. =) (Only if you're actually going to edit an image. If you're just going to swap it out for something else, you obviously won't need this.)
Here is a good example of something where I really felt like I needed to change some images we can use that I just discovered last night while calling to activate my credit card over the phone. Here is the dialer when you start the phone:
Notice those handy letters next to the numbers =)
Once I started the call to the credit card company, it asked me to verify myself by inputting, using the keypad, the letters of my mother's maiden name. So I opened the dialer, and what did I see?
For whatever STUPID STUPID REASON, they REMOVE the letters next to the numbers on the keypad that opens DURING the call, making it extremely difficult for me to type my mother's maiden name in the time permitted, given that no, I don't off the top of my head know where the letters sit on the dialer. So I felt this needed fixing =)
1.) Copy the apk you want to modify from your phone (using root explorer) and transfer to your computer
In this case, I wanted my Phone.apk, which is in /system/app. The vast majority of system apps are in this folder with the major exception of framework-res.apk, which is the phone’s BIG cajone in /system/framework, and as such, should be handled with utmost care. Messing with framework-res.apk incorrectly is an EASY way to brick your phone in a heartbeat.
2.) Unzip the apk using 7zip and look for your PNG's!
Keep the original, untouched, zipped apk somewhere safe on your computer. You’re going to need one to modify and another copy for safekeeping in case you want to revert back to the stock apk, or something goes wrong. Unzipping the apk just makes searching for the PNG you’re looking for much easier, since you can change the folder view in windows to give you a thumbnail of each of the items. And lookee, lookee, here they are in phone/res/drawable-hdpi, right next to other dial buttons with those handy letters!!
3.) Edit your PNG's however you want.
In this case, the work is pretty much done for us! I just swapped out the PNG's without the letters for copies of the ones with the letters, and just changed the names of the files to the original versions, like so:
4.) Using 7zip, right click on the original, untouched apk, choose 7zip, and open archive. DO NOT EXTRACT.
Open archive will let you explore the apk without having to extract it and lose the proper packaging of the apk.
5.) Select all your newly modified PNG’s and drag and drop them into the correct location in the open archive of the original apk, letting them overwrite the old PNG’s.
6.) Put this newly modified apk back onto your phone. Using root explorer, copy the new apk into the /system folder of your phone.
7.) CHANGE THE PERMISSIONS of the apk to match those of the original apk in /system/app.
In this case, long press on the phone.apk, select permissions, and select the check boxes as follows- Owner: Read, Write; Group: Read; Others: Read. This matches the permissions of phone.apk in /system/app
8.) Move the new apk into /system/app, and let it overwrite the original!
9.) Restart your phone!
Voila! Now when I call my credit card company and have to type in names, I can!

I thought it is useful to kept all of them in one place.
But based on your response if you feel it is not necessary and the Mod also feeling the same, Please delete this thread.
I don't mind.

I think this thread is very useful and i will surely subscribe and use this thread in the future

Thank you very much for your support. But lets wait for the MOD's reply.

Just to help your argument, there's a collection of ROM's so why not a collection of tweaks

yup... make a master index of tweaks
and we can apply only those we want separately ..great idea !

Thanks for your support.
Regarding your battery problem (seen in your signature)
Me too faced battery problem. But at first I thought it is an issue with firmware or problem with out G3 itself. But after getting it replaced by Samsung Service Centre it gives huge battery backup, of course with Custom ROMs only.

+1 for this topic. Great job!

Good work! But Jazux shouldn't be given any credits for these, it was knzo who repo'ed it ... Jazux did nothing!

Yeah i can see that lol

Just used some of these tweaks on stock XXJPS (only the ones i found useful for me). I will see the result

plz delete jazux from credits, because he had opened similar thread long back which he had copied from other thread and didnt even care to give that guy credits..so i think jazux doesnt deserve those credits

[REF][DEV] Tweaks for i9003 list [UPDATE]

This is a list of all threads avaiable to our phone, using for ROM developer too...
i decided to post in general, becouse this is not developer threads, developer threads are done from developers and i'm a human no developer.
Adrenaline Shot v14 Universal ​What do these tweaks do?
the first improve is under /system/bin, replace 2 bin with leaked from ICS 4.0 , with GREAT EPIC improvement , 2 bins 're app_process and system_server.
app_process executes, and executes a runtime environment for a dalvik class
The system server is the core of the Android system and as described in the boot sequence post it is started as soon as Dalvik is initialized and running.
like all tweaks , this will add some /system/etc/init.d script , if kernel supports of curse
( for everyone using Gentoo, know init.d too )
the first one is 00remount
Code:
#!/system/bin/sh
#Partition mounts by Dsexton702
mount -o remount,noatime,nobh,nodiratime,nodelalloc,noauto_da_alloc,barrier=0 /system /system
mount -o remount,noatime,nobh,nodiratime,nodelalloc,noauto_da_alloc,barrier=0 /cache /cache
mount -o remount,noatime,nodiratime,delalloc,noauto_da_alloc,barrier=0 /data /data
This script will (re) mount the EXT4 partitions with some "tweaks", like noatime, nodiratime,delalloc and soso.. , speed increased in R/W
the second is 01kerneltweak
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_GENTLE_FAIR_SLEEPERS > /sys/kernel/debug/sched_features
unmount /sys/kernel/debug
using NO_GENTLE_FAIR_SLEEPERS as schedule features, nothing to hard
the third 02journaling
provide to delete cache if its too big
the 4th is 03sysctl
Code:
#!/system/bin/sh
sysctl -p
This is simply call to sysctl ( parameters settings under linux kernel ), its under kernel tweak
the 5th is 04sysctltweaks
this will set a lot of utils things about kernel and its driver ( like governor ) , if people using ondemand it will set ondemand/up_threshold to 65 ( more responsive , but increase battery drain ) and ondemand/sampling_rate to 30000 ^^
05sdcardspeedfix
fixing READ_AHEAD_KB , suggest it will increase sdcard speed ( not too much )
06zipalign
provide to zipalign all /data/app/*.apk files, anything know to apk files are zip archive contains a lot of things, zipalign optimize this archive , major info at developer.android.com/guide/developing/tools/zipalign.html
07vacuum
this provide to "VACUUM" all *.db ( see SMS's DB, etc ... ) to rebuild all *.db better, increase performance too!
08ramscript
i never will use this, this is not designed for our phone IMHO it can be replace with superchanger ( see after )
/system/lib/libsqlite*
will replace sqlite's lib for better performance, sqlite has sync and async method, this will disable sync , theorically it will double the performance in I/O
/system/xbin
it simply provide a sqlite3 bin and zipalign bin, nothing tweaks
Click to expand...
Click to collapse
Thunderbolt tweaks ( this is not avaiable, i upload some script i've download a time ago )​/system/etc/init.d
s78enable_touchscreen_1
Code:
#!/system/bin/sh
#Touchscreen
#Configure touchscreen sensitivity
#Sensitive(Chainfire)
echo 7035 > /sys/class/touch/switch/set_touchscreen;
echo 8002 > /sys/class/touch/switch/set_touchscreen;
echo 11000 > /sys/class/touch/switch/set_touchscreen;
echo 13060 > /sys/class/touch/switch/set_touchscreen;
echo 14005 > /sys/class/touch/switch/set_touchscreen;
this is IMHO the best script i've ever seen , this will increase sensitivity of touchscreen
07sqlite_optimize
this will vacuum and re-index all db, better than Adrenaline's 07vacuum IMHO
S70darky_zipalign
Another zipalign script, useless
*bolt_siray*
this is not developer for our phone, this will working only with adeguate kernel ( we haven't )
S98CFS
it will provide a lot of tweaks using sysctl and kernel proc/ interface
S98system_tweaks
this is a lot of script unify in one script
i edit this to be "better" with our phone, i delete re-mount runtime , adrenaline's 00remount do it better
and modify this part:
Code:
# ==============================================================
# smartassV2
# ==============================================================
if [ -e /sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq ]; then
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq;
if [ "`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq`" -eq 300000 ]; then
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;
else
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq;
fi;
echo "800000" > /sys/devices/system/cpu/cpufreq/smartass/sleep_wakeup_freq;
echo "85" > /sys/devices/system/cpu/cpufreq/smartass/max_cpu_load;
echo "75" > /sys/devices/system/cpu/cpufreq/smartass/min_cpu_load;
echo "300000" > /sys/devices/system/cpu/cpufreq/smartass/ramp_down_step;
echo "0" > /sys/devices/system/cpu/cpufreq/smartass/ramp_up_step;
fi;
to have a correctly step for our processor

"after applied this , my phone morth into blonde, blue eyes galaxy Supersayan [cit.]
THIS IS THE ONLY MEMORY Manager, this provide a better ram manager by android, anyone know that Random Access Memory contains a kernel and all APP run, kernel are loaded in lowest address possible , and all app are loaded when open, android usually doesn't close this, for better speed when you re-open its, but if you have small RAM ( 512 MB too ) this will cause a lot of problem , superchange fix it!
i suggest to use 512HP Balanced ( or Performance ) with Bulletproof launcher + OOM FIX, Nullify lag work too
HOW INCLUDE THIS INTO MY ROM?
Poseidons ROM include this by ****ty init.d script, i suggest to delete and re-apply
if you are not ROM Developer is simple, download latest avaiable by link i provide at top and with ROOT-enabled ( check su ) and Script Manager ( or terminal emulator -> # su -> sh script_location ) follow the scripts guide, remember, using this can cause ( 0.01% ) bootloops, i suggest to use local.prop and init.rc integration
if you are a ROM Developer is more complicated than simple user, for stick you can use:
init.d script ( like poseidons )
local.prop and init.local.rc ( suggest ) under /data
build.prop
init.d script ( i do not see this, for me is the worst way to get it )
init.local.rc:
create a /data/init.local.rc contains

this will make phone more smoothness by renice ( change priority ) the main process will run
i suggest to set your launcher process here like:
Code:
### Launcher apps ###
renice -19 `pidof com.sec.android.app.twlauncher` # TouchWiz Launcher
renice -19 `pidof org.adwfreak.launcher` # ADW Launcher Ex
renice -19 `pidof org.zeam.core` # Zeam launcher
renice -19 `pidof info.tikusoft.launcher7`# Launcher 7

95allinone
This will provide a complete collection of tweaks avaiable, i hate this becouse, a lot of tweaks here are not implemented correctly , like:
Code:
#Part below here edited by me (changed values) Credits to Juwe11
if [ -e /sys/module/lowmemorykiller/parameters/adj ]; then
echo "0,1,2,4,6,15" > /sys/module/lowmemorykiller/parameters/adj

if [ -e /sys/module/lowmemorykiller/parameters/minfree ]; then
echo "2560,4096,5632,10240,11776,14848" > /sys/module/lowmemorykiller/parameters/minfree
fi
if [ -e /proc/sys/vm/swappiness ]; then
echo "20" > /proc/sys/vm/swappiness
fi
zOOM zOOM :
Code:
echo "2560,4096,5632,10240,11776,14848" > /sys/module/lowmemorykiller/parameters/minfree
This is the same things that do superchanger, but this will be wrost for our phone IMHO
Code:
echo "20" > /proc/sys/vm/swappiness
the right value ( in my cases ) is 0, i haven't swap of anyway we dont have to have a swap!
Zipalign Runtime, it will just implemented by a lot of script, this is also the wrost IMHO zip align script i've never seen
Code:
for k in $(busybox mount | grep relatime | cut -d " " -f3) ; do
sync;
busybox mount -o remount,noatime $k;
done;
this will break 00remount script
Code:
for i in /sys/block/*/queue/scheduler ; do
echo "noop" > $i;
done;
if kernel support i suggest deadline
Code:
# Tweak kernel VM management
echo 0 > /proc/sys/vm/swappiness
echo 10 > /proc/sys/vm/dirty_ratio
echo 4096 > /proc/sys/vm/min_free_kbytes
??? WHAT? again?
Code:
echo "interactive" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "cfq" > /sys/block/mmcblk0/queue/scheduler
see upper
Code:
echo "deadline" > /sys/block/mmcblk0/queue/scheduler
What? another change?
this is good:
Code:
# Copyright @ CRANIUM ROM
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs

#End Cranium Tweaks
Conclusion: 95allinone is simply a addiction of all tweaks avaiable in one script without any review and improves for our phone ( in this case, this work ), this will only increase the boot time and break others tweaks installed ( some )
99V6_Superchanger
DO NOT USE THIS, THIS IS EPIC FAIL INIT.D SCRIPT!
Code:
mount -o remount,rw /system
mount -o remount,rw /dev/block/mtdblock3 /system
mount -o remount,rw /dev/block/mtdblock6 /system
*facepalm*
in my terminal:
Code:
# su
# ls -la /dev/block/mtd*
ls: /dev/block/mtd*: No such file or directory
anyway this is not init.d script, this is v6 script , this is not compatible with init.d ,

Redefinite TCP Standard size packet, it will increased overall speed
Code:
ro.ext4fs=1
will set ext4fs prop to android system, increased performance if you are under ext4
Code:
persist.sys.purgeable_assets=1
More speed!
Code:
persist.sys.shutdown.mode=hibernate
NOT COMPATIBLE FOR OUR PHONE, we have not hibernate shutdown mode
Code:
ro.ril.disable.power.collapse=0
is ultra-battery-life mode, when phone're sleeping
Code:
ro.ril.enable.cnap

WHICH GOVERNOR DO U USE?​( ref: Simba501 )
SEE THIS
Anyway i suggest:
- Smartassv2 if you want performance over less battery
- InteractiveX if you want battery over less performance
CAN ANY KERNEL DEVELOPER INCLUDE LULZACTIVE CPUFREQ-DRIVER IN OUR KERNELS? ITS THE PERFECT GOVERNOR , EITHER FOR BATTERY AND PERFORMANCE
EGL TWEAK!​Android header said:
Code:
#
# One line per configuration, of the form:
#
# D I TAG
#
# D: display (0: default)
# I: implementation (0: software, 1: hardware)
# TAG: a unique tag
#
# The library name loaded by EGL is constructed as (in that order):
#
# /system/lib/egl/libGLES_$TAG.so
# /system/lib/egl/lib{EGL|GLESv1_CM|GLESv2}_$TAG.so
#
in the stock ROM the egl.cfg is:
Code:
0 0 android
0 1 POWERVR_SGX530_125
what's meaning?
simply using cpu ( with gpu too ) to render all apps and system
if you modify to:
Code:
0 1 POWERVR_SGX530_125
it will use overall GPU render only, more fast and imho better Battery life because, CPU in our cases with overclock consume more than GPU

Wow!! very good thread!! I am setting up a custom rom, could u tell me what of these could give my rom a better battery life? Thank u man!

Battery life is influence by:
Running Apps
Governors do you use
Memory Manager ( #1 addicted )
If you set /etc/init.d script to set conservative governor and implemented v6 without any stupid app like facebook or bloatware samsung, and your battery seems infinite
in the past i used SCH Rom , its used only v6 and most important tweaks , without any stupid bloatware, battery seems very infinite ^^ like 2% in 5 hours under 2G network

Ok, sorry for my noob question but I am learning a lot of things this days.. where can I find a tutorial about how to set a governor or a frecuency by default in my kernel? Thank u very much

I'm noob too
for frequency are too kernel releated to be generalized,
or if you using XDA_Bam kernel
39frequency
Code:
#!/system/bin/sh
echo "300" > /sys/power/overclock_opp1
echo "600" > /sys/power/overclock_opp2
echo "800" > /sys/power/overclock_opp3
echo "1000" > /sys/power/overclock_opp4
anyway you can create init.d script like
40governorbattery
with:
Code:
#!/system/bin/sh
echo "conservative" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
and see if it stick ^^

Hi.
Are there codes that can remove or dissable the TouchUI aka TouchWiz interface on the i9003 and just use the android deffult launcher?
Another thing something that will easy-up my ram usage and allow more usable ram?
If so how do i implement them?

I just want to add a cool sound and audio tweaks using MagaBassBeats_Mod
First download the MagaBassBeats_Mod_9003.zip file from the xda forum.
Now copy it to the sdcard.
Reboot to the recovery mode.
Now select install from zip file and chose internal sdcard.
Search for the zip file, hit power button, and chose yes.
That's it now you can enjoy a great sound quality.

zRam on Gingerbread

Ok so the reason why I made this topic is because Coertmans asked me about virtual ram in android (2.3.6), which is available in CM9, so I went surfing on the interwebs to find about this zRam, first thing I found was this:
Site: http://code.google.com/p/compcache/ (ramzswap_32a.ko/ramzswap_32b.ko)
Instructions: http://code.google.com/p/compcache/wiki/CompilingAndUsingNew
This is the link to the zRam modules for linux kernels, as I'm not sure if it's able to import it into GB I continued searching and found a GB ROM (CM7) which has zRam. I downloaded the rom and searched for the files that possible could be the zRam. All ram/swap related items I got are these:

About SWAP!
ROM will activate 3 kind of swap
It's will turn ON (only if you have already created swap file on partition, or set partition for swap (the hard way) )
SD-EXT SWAP
SD-SWAP
EXT dedicated SWAP partition
***If you have SWAP already, or EXT or SD-SWAP/EXT-SWAP, no need to run the swap activation scripts.
***I have created 2 scripts for disabling SD swap before use of USB storage.
I have put them in your /sdcard/gscript
so you only need the app (gscript light or full)
then load this scripts, when you need usb storage run swapoff script. when done run swapon.
or you can install dual mount app. i can’t live without it so try it.

SD SWAP THE EASY WAY!
In Easy way Swap you don't need to reformat or even reboot your phone to create swap!
If you installed my ROM and you don't have swap but you want to stay on HIGH END ROM,
Then you can do this to enable SD swap
Download script sdswap200.sh or dataswap250.sh from my mirror.
Run in in GSCRIPT App or copy it to SDCARD root,

So what do you guys think about it? It seems to me that this is really possible on GB

This is what I tried so far:
Code:
adb shell
su
mount -o remount rw /system
busybox dd if=/dev/zero of=/sdcard/swap bs=1k count=250000 > /dev/null
busybox mkswap /sdcard/swap > /dev/null
echo "/sdcard/swap swap swap" >> /system/etc/vold.fstab
echo 50 > /proc/sys/vm/swappiness
swapon -a
Now I don't get an error, but also nothing seems to happen, I'm going to try to make the sdcard "swappable ready" the manual way now
edit: Hmm I can only pick my internal sdcard for partitioning the sdcard, someone knows how to do that for external?
And how can I see if the virtual ram is actually working?
btw here is the mirror with the files I used: http://www.bourseanalyse.fr/dorimanx/
btw, totally of topic, but I saw 2 cars on fire so I made a video

The easiest and the only way i know of to check how ram, swap, and memory is used is by going into Terminal Emulator and typing in "free" and click enter... (without the quotations)

Ok thanks, used: "free | grep Swap" seems it's not working yet.

Hello
do you know the app swapper2 ?
it do the same what you try to do here !
But in the german forum there are some people who bricked their device with this app so i just want to say that you really have to pay attention with swapping

they bricked it because of partition of internal sdcard If all of us will partition internal sdcard we have more than 50% chances to brick our device. It seems that partioning internal SD affects the 1-8 boot partitions (dunno how to explain it better) I`ve just woke up lol

Also we need a kernel that supports swap
And we don't have such a kernel

if u are getting all 0's in swap then it is not working... i thik you can try going thru htc dream (G1) gingerbread roms.... they used swap and zramk a lot... well it was essential for the rom to run on that device
If it looks like this (with zeros in the swap line), you do not have swap/compcache:
total used free shared buffers
Mem: 97932 96640 1292 0 272
Swap: 0 0 0
Total: 97932 96640 1292
If it looks like this (with anything other than zeros in the swap line), you do have swap/compache:
total used free shared buffers
Mem: 97932 96004 1928 0 332
Swap: 24472 0 24472
Total: 122404 96004 26400

I had a swap partition on my galaxy 3 and i just wanted to say that it isnt fun...it makes the phone laggy cause you can never have a sd-card which is as fast as a ram module
Sent from my GT-I9001 using XDA

Yes! SDcards even class 10, ain't that stable. Anyhow what's the big deal ?
we never fall short of ram on our device.
Had tried ram swapping on my I9003 and i managed to screw up everything,made it a paper weight (Hard bricked it).
Had to get the board replaced from samsung, on the good side i got the latest latona board with 16gb onboard memory
but i no longer have the i9003

I tried swap while I had Galaxy 3 (it only has 256MB RAM) and I didn't like it. Also many other people reported that it was only slowing down system (even with class 10 cards) SD Cards just aren't fast enough to be used as a RAM...plus, Android is based on a though that free RAM is wasted RAM, right? 512MB for our phone is enough for me, and I've never fallen short of RAM..swap is not needed..but that's just my opinion

I'm not going to continue on this anyway, making your sdcard a swap drives really ****s it up, when I tried to install an app my phone shut down..

[Tweak][Guide] Init.d Tweaks

Init.d Tweaks
(Needs ROM (Kernel) With init.d Access And Busybox, Open Empty File In Text Editor (Notepad ++ Or Similar), Insert Tweak You Want In Header,Save in /system/etc/init.d and name it Lomething Like 73tweaks)
1. Strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. Internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;
echo "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;
echo "256960" > /proc/sys/net/core/wmem_default;
echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. Vm management tweaks
Code:
echo "4096" > /proc/sys/vm/min_free_kbytes
echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;
echo "0" > /proc/sys/vm/swappiness
echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio
4. Misc kernel tweaks
Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;
echo "10" > /proc/sys/fs/lease-break-time;
echo "500,512000,64,2048" > /proc/sys/kernel/sem;
5. Battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
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
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
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
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(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 $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
Code:
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(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
13. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
14. GPS.conf
(create or edit your /system/etc/gps.conf with a text editor)
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Warning: Using these tweaks may brick your device. Use it with caution.

I make and init.d script and i copy your custom values to my init.d script. However, on net speed tweaks, the tcp_rmem and tcp_wmem didn't change the value at all even i edited it. Any help?

Should it be in text file or script file?

So we create a different text document containing each code for each tweak?? Not all In one document in the init.d folder??

Nice write up, bro. Thanks. Will have to try.

Guys so why aren't these enhancing tweaks and buildprop tweaks already available in our phones? Why aren't our phones optimized?

Tweaks good for one person or situation are not necessarily optimal for every case in general .

Thanks for suggesting new Cm12 kernal.
As of cm11, X264 encoding is important for me, plus their were some other minor bugs in that build. Though i agree its the best build compiled rom for Trend.
I will myself start some project after June~July.
What happened to your device though? You are among the few members who are guiding peoples on threads related to this device and i really appreciate it.
