[Q] Changing Min/Max Frequencie Limits in Cocore - Galaxy S Advance I9070 Q&A, Help & Troubleshooting

I'm using cocore 6.8 + JB Stock DXAMD1.
As the main Cocore forum says it is not possible to use no-frills to change the min/max CPU frequency limits. (http://forum.xda-developers.com/showthread.php?t=2140597)
On JB,we cannot tweak min/max scale freqs via apps like SetCPU.
Here is the method.
cd /sys/power

For example: set 400Mhz as max limited
echo 400000 > cpufreq_max_limit
Click to expand...
Click to collapse
* When you switch on/off,power saving mode,this tweak will be overrided.

So when I try to change the value either using Terminal Emulator or ES Explorer Text Editor, the change will revert back after a few moments! Power Saving is off. Any idea of what is wrong? How can I change the min/max CPU frequencies?
BTW what does "Min Frequency Limit" means? Does it mean the CPU must work at this rate even if it has nothing to do?!

Wait, what?
You cant use nofrills for changing cpu frequencies?

No. I cant. It will change governor and IO scheduler but the min/max freq. wont change. (Although no-frills will show a success toast but the limits are the both 1GHz)

It always shows 1ghz, but did you checked statistics?

Ow...Thanks for your reply. The statistics is showing that CPU is at 200MHz now! So it seems that no-frills is working! But it was showing me the correct values before changing the kernel!

[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 )

[Q] Optimal settings for MINI CM9

How well set the settings to the optimal CM9 MINI ROM? I know it was already somewhere, but I can not znaleś.Bardzo mainly I mean if ZRam to be enabled or disabled? And how to set the processor.
Advance thank you very much
If I could give it some help thanks
Smartass v2 cpu governor - cpu frequency 122 - 729.
Z-ram when ur not using supercharger then 18% if u do then disable it..

I Use Smartass v2 cpu governor - cpu frequency 122 - 600 works well.
The problem is that the battery is short-lived
Relative Zram I don't have opinion.

msm-dcvs Governor

GUys anyone know why the msm-dcvs governor for our Xperia SP cpu is buggered?
it's supposed to be Krait optimized, yet I just checked the governer parameters on Trickster Mod and it's got the MAX CPU speed set at 384 mhz
I tried changing it and applying it in Trickster Mod, but it doesn't apply nor stick ...
all the other Parameters are 0
any ideas guys

I seem to be having the same problem. Running 257 with stock kernel (LB +root). The MSM-DCVS kernel doesnot seem to be working. it is always stuck at the min frequency. is there any way yo fix this?
I donot plan on moving to 4.3 stock as the comments here arent very good about the experience.

[Q] Overclock and Underclock App ???

i want a power saving app which can underclock the mobile depending on the standby time or usage and i want to require root only because i dont want to put a custom kernal so anyone have any suggestions ?
no-frills cpu control just search no frills on the play store
this one is by far the simplest one out there. if you just want to overclock and underclock your device this is it. can also change governer and I/O scheduler

[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

Pegasus and sioplus
OR
Hotplug and sioplus

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.
