[Q] OverClock -Governor- Antutu CPU Master

HELLO AND SALAM SATU MALAYSIA
Since i was newbie about android,
i try to overclock my Xperia X8.
so i went to market and i found Antutu CPU Master.
the problem is i found something that i never heard before.::::::
"GOVERNOR"
could someone told me..what is governor actually...
and what different better the governor module?
i only found about smartass..the other module..i didnt find in xda forum.
i hope someone could help me here..before i accidentally brick my phone.

Cpu governor is control the Cpu freq.
- The OnDemand governor is the default option used by Android. It scales the CPU speed between the minimum and maximum speeds depending on CPU load. If the system needs more speed, the kernel will rapidly scale up the CPU speed.
- The Conservative sets the CPU speed in a similar way to the Ondemand governor, but scales the CPU up much less rapidly. This would theoretically save battery power, but may lead to less responsiveness.
- The Userspace governor is currently useless. It’s another way for applications to set the CPU speed that setCPU does not use.
- The Performance governor always keeps the CPU at the maximum set frequency.
Additionally, he makes reference to another option, which is not currently part of the setCPU app, so I am assuming that this is one that was removed in later versions.
- The Powersave governor always keeps the CPU at the minimum set frequency.
- Except for “Userspace,” no matter which governor you set, the CPU will always stay within the bounds of the maximum and minimum speeds you set in setCPU.

I'm not using any app. I overclocked in my system (alfs+GDX). My governor is OnDemand. Min 129mhz - max 748 mhz.

wifi n vib work very well with my linuxperia arch v1 rom.
i use antutu benchmark..i get 1881..
superb ..thanks a lot.

1881 good. Do you like LinuXperia v1 ? Come soon LinuXperia Esca Arch 3 ( overclock, bravia hack, xloud, dsp manager vs )

[ICSbeta] finally a responsive touchscreen + battery life *try this* : UPDATE 4/28/12

ok, nothing seemed to be making the touchscreen responsive with the ICS beta n its derivatives.
except one thing just did.
i changed the sampling rate from 200000(2 lak) to 20000 (20 hazar), n of course i had to change the up-threshold so i changed that to 95 (i did all these in rom-toolbox's kernel tweaks settings)
now everything is super-responsive (app startups, physical buttons, onscreen buttons, switching, yo name it) N while you are just lets say reading stuff on the screen, the cpu is generally at its lowest
what that means is : both responsiveness and higher battery.
please comment.
UPDATE : check the 7th post on this forum for more tweaks for snappy app launching n switching here http://forum.xda-developers.com/showthread.php?t=1570374#post24186676
UPDATE : ADDITIONAL TWEAK (more battery life) : in rom-toolbox change powersave bias to 35 (in rom toolbox) : saves a lot more battery by preventing the cpu from rushing to full-frequency while you are doing simple tasks like flicking the screen.
UPDATE : 3/31/12 : an interesting observation about "force gpu" 's causing poor performance on my post here : http://forum.xda-developers.com/showthread.php?t=1570374&page=2#post24266342
UPDATE : 4/7/12 : want even more battery life n smoothness?
add these to your build.prop save , reboot into recovery, clean dalvik-cache and /cache partition then reboot into system. things should be faster. and oh, underclock it.
ro.kernel.android.checkjni=0
dalvik.vm.execution-mode=int:jit
ro.ril.disable.power.collapse=0
ro.mot.buttonlight.timeout=1
dalvik.vm.verify-bytecode=false
dalvik.vm.dexopt-flags=v=n,o=v
you can also do a semi-odex using titanium backup's integrate system dalvik into rom thing, but then you won't be able to change any file in the rom (like applying patches, mods etc until you've either done undo integration thing in titanium backup or just used adb shell to delete *.odex from /system/apps n rebooted)
UPDATE : 4/28/12 : if you are using a derivative of the .562 ICS then you can change the kernel tweaks/sysctl settings to dirty_ratio = 80 dirty_background_ratio = 20 and vfs_cache_pressure = 20 to get snappy app startups up_threshold and powersave_bias can both be set to 90 and select ignore_nice_load. if you use lots of apps then raise the dirty background ratio and dirty ratio both by 15 points and reduce vfs_cache_pressure by 15 for low cpu usage while the apps are running. i've noticed that many of the custom roms have started getting my tweaks or similars preincluded , plus the official ics is much better than icsbeta in memory management. and oh, use arcknight kernel. its super awesome for both features and battery life. i switch my governor to interactivex or smartassv2 when i am recording using the 14mbps camcorder mod, and then back.
the android backup & restore under person in settings should be turned off. it takes a lot of cpu, battery, data n memory. its aweful.
if this works for you, press the thanks button.

How can this be done?

i used rom toolbox pro, its free version is available here - https://play.google.com/store/apps/details?id=com.jrummy.liberty.toolbox
anything else that can edit sysctl.conf (e.g. https://play.google.com/store/apps/details?id=com.jrummy.sysctl.config and https://play.google.com/store/apps/details?id=scd.atools ) will also work.

Gonna try it

system seems to be a bit snappier
thx mate

thnx mate.

for snappy app switching i discovered another bunch of settings
in rom toolbox's kernel tweaks under performance, change min free kbytes to [CORRECTION]8192[not 8096] (or [UPDATE] 6144 - whichever one you like), dirty ratio to 95, dirty background ratio to 70 and vfs cache pressure to 5 (n of course check the apply on boot option)
let me know how you like this additional tweak
UPDATE: some observations ; high dirty ratio causes lower cpu usage n faster app-switching, low dirty background ratio causes faster app startups but uses too much cpu, vfs cache pressure above 5 or 10 causes high cpu usage n lags. (i use lots of apps)
UPDATE #2 FURTHER IMPROVEMENTS (fast all around with acceptable cpu usage, super app switching, n decently fast launcher without sacrificing cpu-speed n battery life)
Kernel Tweaks :
reduce dirty background ratio to 50
check the OOM kill allocating task (if your device crashes after this, uncheck this, it may kill the android system n android os processes as well in some cases)
Auto Memory Manager :
foreground 6
visible 8
secondary 32
hidden 40
content 48
empty 120

Thnks

The up-threshold and powersave bias settings do not stick for some reason. They return to default values after a reboot even though Apply on boot is checked.

It is the same for me. I guess we'll have to review each init.d script to see what is the one that is changing these values on restart.

check the 98kickasskernelizer (i'd find the respective values - especially min-free n change them in the script itself), there are two other not so popular scripts out there too that you may be using.
please share with us whatever was causing the overriding of rom toolbox's (or sysctl etc)'s settings.

Hey there thanks for the tip. Already tried it but I don't think there's any major improvement. In fact, antutu graphic score is down a bit. But don't know why. Maybe just my phone.

the benchmarks dont tell you about usability. better responsiveness is due to faster cpu response to situations.
antutu's benchmark tests for continuous high performance (battery hogging w/lags) while running just one app.
my settings are for giving great experience (touch, app switching and app launching as well)
think of it as antutu being a mr. universe test, while mine are a gymnastics olympics tournament.

Well thanks. A lot less sluggish when scrooling..

i tried 6144, restarted n it sticks. try 8192 (i haven't tried restarting after that) : my 8096 was a mistake - i accidently doubled 1024 to 2048 n that to 4096 and then stupidly to 8096.
it is possible that numbers that are not multiples of 1024 are ignored if set on boot.
that occurred to me since init.d scripts are loaded much before rom-toolbox gets a chance to do its magic.

I tried and it stuck after a reboot. It is working fine now. My battery is lasting more indeed, but wifi is always on, even after I made the suggested changes. I guess I'll have to reinstall Doomkernel v04 and JJ's ROM from scratch. But even with wifi always on, I'm having better battery life and less lag.
Thank you again.

i found another interesting thing today.
the force GPU for 3d in the settings -> developer options actually uses a lot of the cpu and causes lags. i turned it off and have instead done the following
Get rid of CPU rendering:
Navigate to /system/lib/egl/
Open the file named "egl.cfg"
Delete the first line. It should say "0 0 android" or something similar
Go back into the egl folder and delete libGLES_android.so
What this does is remove the entire soft-rendering pathway from the OS.
source : http://www.ifans.com/forums/threads/ics-performance-tweaks.369959/ ;
now, i have changed the powersave bias in teh romtoolbox's kernel tweaks to 95 instead of {correcton}35{not]95. the cpu is spending more time @ 122mhz and deep sleep now without lags (which means more battery)
if this thing works for you, please press thanks.

[Q] NEED : Explanations for Advance options!

Today morning i flashed latest SHIN Engine.
And roaming around, found countless advance user options.
I am a game lover , always searching options to improve performance.
Thats why i request ,
please somebody explain what the listed functions do and what are the effects ?
1. Compcache RAM Usage
2. Surface Dithering
3. 16 bit transparency
4. Kernel Samepage merging
5. KSM Sleep time : 1000, 1500, 2000, 2500, 3000, 3500, 4000
6. KSM Page scan : 64, 128, 256, 384, 512
7. Battery Polling : 1s, 5s, 10s, 20s, 40s, 1m
8. IO Scheduler : sio, deadline, cfq, bfq, vr, noop

Options have explanations written down usually...

Actually you are right but,
let take an example, KSM Page Scan
there written, improves performance
But its not the explanation, might this improves daily use functions and meanwhile badly affect graphics(gaming) performance.
Thus i want to know what th function actually doing
such that we are selecting max. cpu speeds we know what actually we doing.
Although, down the option it only written MAX. cpu frequency
And also, considering KSM page scan,
what i have to set i.e.
if i set higher value , then it improves or opposite.

[Q] Best developer / performance settings?

For speed, what are the best settings to have? I'm running CM10.2 now, this ROM in particular, with this Kernel. No "performance" scripts, as I tried one and my phone wouldn't boot and had to restore nandroid backup.
For example:
zRAM: disabled, 10%, 18% (default), 26%
Allow purging of assets y/n?
Kernel samepage merging y/n?
16bit transparency y/n? (yes seems obvious but I don't know if it might somehow make it slower)
Right now I'm using SMARTASSH3 governor with max cpu at 825. I can go up to about 900mhz but it doesn't seem to make much difference to be honest.
I/O scheduler: I leave this as NOOP on default because whenever I change it my phone because really unstable and crashes all the time, but if you can suggest one that might be better I'm all ears.
Dev options:
Window animations of course can be reduced or disabled.
Force GPU rendering for 2D drawing y/n?
Force 4x MSAA y/n?
Disable HW overlays y/n?
Background process limit? Whenever I try to change this the setting never "sticks", and I think it seems to cause instability.
Don't keep activities seems like an obvious one to enable, but if you are switching between multiple apps then it could be perceived slowdown as it has to load them up again from the start?
Does the amount of available internal storage make a difference to speed? Right now I am at 14.8mb free, is this used like RAM or something and I should link more apps to SD card? (Link2SD)
Thanks in advance if you answer these extremely common questions..

ZRam: Yes (but the battery life will get shorter!)
Allowing purging of assets: Yes
KSM: Yes
16-Bit transparency: Yes
SmartassH3 is a good choice. If it's getting laggy use smartassv2. I usually use 200-800MHzh.
I/O scheduler: Idk which ones the MA6 kernel has, but ZEN is one of the best.
You can limit the background processes to 3-4, it's up to you and your personal use.
If you have apps that you don't use, deinstall them. Because some of them are running in the background and so they'll use RAM.

On CM 10.1 I got a very slow phone with zen scheduler. Now I'm using deadline and is faster than before. Governor is smartassh3 (supersmooth governor) and 864mhz overclock. This combination works very good for me. Please report back your experience

my phone
(main)
governor: interactive (320-800MHz)
scheduler: sio
(screen off)
governor: ondemand (245-748MHz)
smooth and responsive, try it.

How is battery life with these settings on CM10? Can I aspect at least 10 hours of moderate use?

[Q] Best CPU Governor and I/O Scheduler for One Power Guard

Hi,
I'm using Co-Core 8.2 and I want to test One Power Guard to improve my battery life.
But I don't have any idea about which CPU governor and I/O scheduler to choose.
Could someone tell me which combination provides the best balance between power-save and performance?
I'm on Jelly Bean 4.1.2
NB. Cocafe recommends PegasusQ as CPU governor and either SIO/ROW for I/O scheduler but I would like to get some feedback from people already using One Power Guard.
Thanks in advance

Thanks for the answer. I will give a try with Pegasus
However I noticed that sioplus is not available on One Power Guard settings. Only row and sio.
Is sioplus available in Co-core 8.2?

These apps like this just drains your battery. If you want play with CPU, download a CPU controller app. (like SetCPU) and install CoCore 9.0 which is newest version.
When you don't use phone ; 600 MHz Max & HotPlug
When you don't use phone V2 ; 600 MHz Max & Ondemand & deeper sleep status
When you lock phone, don't decrease speed (too much) because it will use whole CPU if it needs ; 800 MHz Max & Ondemand Q/Lulzactive Q/Pegasus Q
When using ; 1000 MHz Max & Ondemand/Interactive/Lulzactive Q/Pegasus Q
When you get mad and crazy about performance, lock the min to max; 1000 MHz min and max & Ondemand & SmartAss (still exists or not I don't know)
If you increase minimum speed it will keep it. So I suggest always keep min to 200MHz. (if exists 0 MHz I don't remember it too)
Edit: and don't go deeper sleep if you use hot plugger governors like Hotplug, Pegasus, Lulzactive Q

Thanks guys,
I will compare the battery draining with One Power Guard just to give it a try.
If I don't notice any improvement then I will tweak with SetCPU

Hi again,
What exactly do you mean wit "deeper sleep"?
Is that an option or when the display is off after several minutes?
Sorry for my ignorance

Go to the CoCore's thread you'll see. It's deep sleep level which can increase your battery life when you don't use the device. It's not about using, it's about when it's stand-by.

Ok
After one day even if One Power Guard is a nice app I prefer to switch governor depending on the display status. So I was thinking about using tasker (instead setCPU) which is already running on my phone and this way not adding more background processes.
I set a couple of task using the CPU control from tasker. It is working fine switching governors but I noticed that the frequencies (min and max) don't change. I tried even with shell script and still I don't get to set the max frequency. Then I prefer to make you a couple of questiosn:
-In tasker when using the CPU control. If I change governor. Should it be set in both CPUs (0 and 1) or only in a single one? In my case i set the governor in both.
-I use the terminal to check the current governor and max frequency (for instance for the cpu0)
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor​cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq​
As said above the governor is succesfully changed but that's not the case for the frequency. Then I tried to run a shell script to change the max frequency as follows:
echo #frequency > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq​
But it seems not working neither. So I wonder if I'm doing something wrong.
NB. By the way I'm happy using the governor hotplug while not using my phone (thanks for the advice). In normal use I set pegasusq with sio and seems working great.
