[kernel module] smartassV2 governor for Defy Mini

Bernd.Defy · Aug 11, 2013

Hi there,

based on the work of @viulian and @AnDyX here at xda, i've ported erasmux' smartassV2-goveror to a kernel-module for Defy Mini.

It's easy to use:

1. download the attached zip
2. place the defymini_smartass2.ko anywhere on your defy mini (i prefer /system/lib/modules)
3. install the module

Code:

insmod /system/lib/modules/defymini_smartass2.ko

4. start a tool like no-frills cpu-control
5. choose smartassV2-governor, 245min / 600 max.

ToDo:
* create init.d - script:
- which detects current (overclocked?) max-speed
- loads smartass-module then
- changes governor to smartass with detected max-speed

Please try it and give feedback, i hope, there is a little more batterylife now.

Regards,
Bernd.Defy!

Is it also working for defy? or why is it on this forum?

Bernd.Defy · Aug 12, 2013

Sorry, just for Defy Mini. There is no special subforum for the mini, so this one seems to fit.

@Bernd.Defy You can load the module on boot by using an app called Set Xperia which works for me to load the smartassV2 governor on boot.

https://play.google.com/store/apps/details?id=com.SetXperia.Inteks.org&hl=en

The smartassV2 governor has a delay on waking up but otherwise this governor gives you better battery performance.

Thank you for your information about SetXperia. I already use another tool by inteks (developer of setXperia) - SystemCleanup. I was in contact with him, and he added the possibility to move system-apps to /flex-partition in this tool. After removeing all the bloat from /flex partition, there wera ~60MB of space there. So, i took all my "important" apps, made them system-apps (inkl. odexing to prevent creating files in /data/dalvik-cache) and moved them to /flex. What system cleanup does is create a symlink in /system/app to /flex/app, similar to link2SD, but without the need of an 2nd partition on sdcard.

For the governor: i created a little init.d-script to load and set the governor at boot. Works great.

Nice module. Seems to work fine.
I'll just add in the 66ocmodule script what's necessary to load it on boot.

I'm iterrested in doing that as well.
Could you please develop this sentence ?

That's what i put in my init.d-script:

Code:

#!/system/bin/sh 

insmod /system/lib/modules/defymini_smartass2.ko
echo "smartassV2" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 245760 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Slightly OT:

I played around a little with /system/app and /flex/app and what i found out is, that you can't install anything to /flex/app directly, but this folder behaves like a second /system/app, like an appendix. So i tried to move apps from /system/app to /flex/app and - it worked. I moved them directly (and did not create a symlink in /flex/app), and after reboot, all apps were still working.

So this is what i did for all important apps that i don't want to Link2SD (via Link2SD

):

1. removed all bloat from /flex/app --> 60 MB free
2. moved all system-apps, that will probably never update, to /flex/app (for example phone.[apk|odex], Calendar*.*, ...)
3. used SystemCleanup to convert "normal" apps to odexed system apps. If you odex these apps, they store their odex (in general the same as a dalvik-cache-file) in /system/app, not in data-partition. Caution! Some apps do not work after converting. I converted the following apps to odexed system-apps with success: Holo Launcher, Playstore, K9 mail, SuperUser, Wetter.com (guess where i'm from!

), CpuSpy, Hacker's Keyboard, Link2SD)

When there are updates for these "system-apps", then i use SystemCleanup again and integrate the update in the system-app and odex it again.

HTH,
Bernd.Defy

@Bernd.Defy, first congratulation for your consistent job. You (or someone else) may tell me if there are any apps originally in flex/app that we should NOT regarding as bloatware ? Which ? Thanks in advance.

--> removable, it's part of this social-graph-widget-thing
ActivityWidget_tinboost_mdpi.jar
--> removable, it's part of this social-graph-widget-thing
BatteryManager_mdpi.apk
--> If removed, System-->Power does not work anymore (but this is not needed, you can see battery-usage in system-->telephone info-->battery)
blur-services.apk
--> thrown away
BlurUpdater.apk
--> thrown away
BotaSettings.apk
--> thrown away
CMP_MMCP_AmazonFR_NoFM_1.2.104.apk

--> no bloat, removed it anyway.
GoogleQuickSearchBox.apk
--> no bloat
LatinImeTutorial.apk
--> no bloat
Maps.apk

MarketUpdater.apk
--> deleted it
MediaUploader.apk
--> deleted it
MotoAccuWeather2_App_tinboost_mdpi.apk
--> deleted it
MotoAccuWeather2_Service.apk
--> deleted it

--> if you dont't like moto, you can consider this as bloat
MotoWeatherLiveWallpaper_tinboost_mdpi.apk
--> if you dont't like moto, you can consider this as bloat

Quickoffice-Motorola-SP-5_0_104_V_Signed_2012-01-03_10-18-47.apk
--> no bloat, but i did'nt need it, so i deleted it
SetupLite.apk
--> if you dont't like moto, you can consider this as bloat
SocialGraphCallService.apk
--> if you dont't like moto, you can consider this as bloat
SocialGraphService.apk
--> if you dont't like moto, you can consider this as bloat
SocialGraphWidget_tinboost_mdpi.apk
--> if you dont't like moto, you can consider this as bloat
SocialWidget_tinboost_mdpi.jar
--> if you dont't like moto, you can consider this as bloat
Street.apk
--> streetview

--> no bloat. nice keyboard (better than swype found in playstore, smaller, faster, better keyboard-layouts)
Talk.apk
--> i say: no bloat.
ToggleWidgetsGlobal_tinboost_mdpi.apk
--> nice toggles, but widgetsoid is better
Twitter-3.0.0-release.apk
--> bloat
Upgrader.apk
--> ?
VoiceSearch.apk
--> no bloat, if you like to talk to your phone
WorldClock.apk
--> no bloat, but useless for me
YouTube.apk
--> well, i say: bloat.

Remember, /flex behaves like /system: it's read only. Updates are written to /data/app, so move them to /flex/app and delete previous versions.

Operation not permitted

Hi,

Been a while since my last visit here...
I did not succeed sending this command to my mini... I get "failed (Operation not permitted)" message in terminal emulator...
My folder permission is set to RW, but no luck...

Were do you think the problem may be?

Thanks a bunch!

Hi, in terminal type in su before typing in @Bernd.Defy command. You can also check out my custom kernel here for Defy Mini to improve performance: http://xdaforums.com/showthread.php?t=2676423

OMG....
In was dumb enough not to enter su command in terminal...
Geez....
Still, after a reboot the phone looses this governor and revert back to performance governor.
Shouldn't remain in phone's memory?

Thank you again for your work here.

Cheers

You will need an init.d script to keep the module loading on boot.
I tried to include smartassV2 governor into by custom kernel but it ended up in build errors. The only good uses you can get with my custom kernel is that you get root access within the kernel, performance improvements (my phone seems to boot slightly faster with my custom kernel), and better overclock with @Bernd.Defy's overclock module.

Hi there,

I have installed a software called universal init.d support.
It runs ok, installed the module again, restart applied, module is gone...
I don't understand...
Cannot keep the module loaded and don't know the reason even if all your conditions are met...

Thanks for your time.

I will write an init.d script when I have time.

Instructions:

Please use a command prompt / terminal to type in these commands.

1.

Code:

adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock11 /system

2.

Code:

adb push defymini_smartass2.ko /sdcard

3.

Code:

adb push 77smartassV2.txt /sdcard

4.

Code:

adb shell mv /sdcard/defymini_smartass2.ko /system/lib/modules/

5.

Code:

adb shell mv /sdcard/77smartassV2.txt /system/etc/init.d/77smartassV2

6.

Code:

adb shell chmod 777 /system/etc/init.d/77smartassV2

7.

Code:

adb shell chmod 644 /system/lib/modules/defymini_smartass2.ko

8.

Code:

adb shell chown 0.0 /system/etc/init.d/77smartassV2

If you are wondering @MadK9, defymini_smartass2.ko is in the first post of this thread but it must be in the folder that I specified i.e. /system/lib/modules/. Just use the commands I provided above and the init.d script should work.

Enjoy.

@MadK9 @MauroSZ When using a command that invokes an adb shell command make sure you type in

Code:

adb shell su -c "command"

so that you don't get permission denied message.

For while i can't do anything but I will always hit thanks. I am waiting either my wife or my son to leave her/his device in my hand.
