[Q] How to set cpu frequency on Dalingren's new kernels released today

Hi,
Sorry for the newbish question but I noticed Dalingren released new kernels today(02/23) and they all run at stock speeds. This is my first try with a new kernel and am running Froyo Customized 0.6.8. Just wondering what is the proper way to OC these new kernels? Do we have to use a SetCPU type program or is there a setting somewhere I am missing or a file that needs to be edited? I just don't want to break anything by doing it the "wrong" way.

Yes, you would need to use SetCPU to hit the higher clock speeds. I set my profile to vary between 800 and 1100 MHz OnDemand. I also set my "screen off" profile to vary between 300 and 600 MHz OnDemand so I reduce battery consumption when not using the NC.
It has worked well for me, been using that strategy for several weeks on the older version of the kernel. Just updated to the new one today and it still works great!

SetCPU is available in the Market for $1.99, but the developer makes it free to XDA members here: http://forum.xda-developers.com/showthread.php?t=505419
Its a really nice gesture to his fellow modders, so if it does what you need please consider buying it for $2.

this is a good way to go. I have been using it on my HTC Hero and now on the Nook.
It does not have profiles like SetCPU it is just clean and simple.

This is basically the same settings is use also. I set the lower threshold on my profile to 600. Go ahead and spend the $2 on setCPU. It's easy to set, and works well.

SetCPU for HC4-v2
I installed setCPU . But the top end limit is 600mhz. :-( I tried new kernals, old kernals... its always 600mHz.

[Q] Setcpu + stock kernel

Hi !
i have a LB and so, i have only a stock kernel. I would like to use Setcpu and profile to save my phone, can use it ? can i undervolt this ?
Thanks !

No, you need a custom kernel for UV/OC/UC so setcpu or other similar apps are of no use to you.

Agreed, except you will be able to profile using stock governors and I/o schedulers if you are rooted, you will also be able to set a lower max or higher min process speed if you should choose. I have not used setCpu yet although I have it installed, annoyingly it keeps requesting su even tho I'm not using it :/

True, you can set stock governers, but when it comes setting cpu speeds you will only be able to set stock speeds. Since the stock speeds are all aready availabe you will only be able to increase the lowest speed and decrease the max speed which is not what he wants to do, and IMHO no something to bother doing anyway.

Indeed, and thats what I said
However I would disagree that it's pointless - you could (for example) set profiles for when battery >40% max cpu = 1G - this would slightly increase remaining battery life - you can also set temperature based profiles and even profiles for specific apps.
But in truth, most of these are rather redundant given that the T already has battery saver/thermal throttling and decent enough processor to cope with heavy load - still, will be very useful once we get a few more custom kernels to play with (eagerly awaits the arrival of DOOOOOOM!!!)

I tried SetCPU when I was rooted on 303 firmware.
It worked ok for about half a day and then locked in a CPU mode and hammered my battery until the phone went flat. The phone was pretty hot when I noticed and picked it up.
Might be a one-off but worth keeping look out for if you are using with a LB like I was.
If I helped hit thanks!

ok
thanks for all information !

Decrease min CPU frequency???? SGS3 LTE

Guys,
I'am wondering if its possible to set min CPU to lower than 200Mhz????
I used to have a HTC Incredible S and lowering the min CPU to 133Mhz it helped with battery saving.

that 200 MHz or whatever value, is the sleep frequency right?

Hi mate,
Have you tried playing with the CPU frequency settings located in:
/sys/devices/system/cpu/cpufreq/pegasusq/
You will need Root Access and to mount the System as read/write in order to save the changes.
They are also referenced in /init.rc, so you can probably change the settings in the Kernel too
Have a great day!
-Shaz

if this trick works you can set it to 1MHz....But the big question: will the phone work normally? i mean if i get a call phone will act as normal?

No, in deep sleep the frequency is different. That's why a idling device wastes more battery than a deep sleep one.

[INFO] Android One Overclocking

Hi guys !
I've been trying to add overclocking to Android One, I'm able to add another frequency (both Overclock and Underclock) but I'm able to test it, the 1391 MHz was the stablest overclock frequency I could get. Decreasing frequency lower than 590 MHz makes booting slower (I don't know why).
Check the screenshot, I'll report more news once I get things finished.
I have attached the mt_cpufreq.c just in case anyone have a kernel source and want to try the overclock.
EDIT: It seems max frequency can't be changed since it's hardcoded to 1.3 GHz, it keeps jumping to 1.3 GHz when screen is turned off, but the frequency sticks when phone is rebooted, but not on screen off.
Click to expand...
Click to collapse
EDIT2: It seems that mt_ptp also controls DVFS, which is interesting. This means we have to edit two files and disable restoring frequency to its default table.
Click to expand...
Click to collapse
EDIT3: I found this in mt_cpufreq.c :
Code:
static unsigned int g_max_freq_by_ptp = DVFS_F0;
Which is defined in the same file, the DVFS_F0 is :
Code:
#define DVFS_F0 (1300000) // KHz
The DVFS_F0 is 1.3 GHz, this might explain why the max frequency keeps jumping to 1.3 GHz when screen off. But this is just an assumption.
I've added mt_ptp.c just in case anyone want to checkout and help the development.

Interesting
I had given up all hopes of low level modifications such as over clocking /underclocking/under volting and kernel level wake gestures like double tap to wake etc... This gives me something to look at. Thank you

It seems that max freq can't be set to other than 1300 MHz / 1.3 GHz.
Can anyone here using CM12.1 confirm this bug ? Since it might be because of the ROM but I'm unsure here, it can be either ROM or my custom built kernel.
BTW, 470 MHz isn't fully implemented, the kernel refuses to use it. It might be because I haven't defined it in the volt switch function.
EDIT: Another possibility, it seems on mt_ptp, the clock are either hardcoded or defined in other file. So I have to say that overclocking might be still far away to be achieved.

Why not Overcloack the GPU ??? (NOOB HERE)

GPU is another thing here, it's still too hard to OC CPU itself.

Does the Android One uses MT6582 or MT6582M?(Are there more differences between them other than GPU frequency? MT6582: [email protected]; MT6582M: [email protected])

MT6582 I believe. I never checked but on kernel the chip folder (/arch/arm/mach-) is mt-6582

Can it be used on a 5" screen and MT6582M?

Depends, does your phone kernel source exist ? If yes, then you're free to try. If not, then don't.
BTW, please don't think this is just a 'install the .c file and get overclock'. It needs many work, and such, I advise you to have at least some advanced knowledge of Linux Kernel.

i had overclocked sprout in almost every possible sorts i can do. you have not defined 470mhz freq table properly in the file , pm me if you want to know my experience. :good:

Not really, but yeah, it kinda drain battery more than normal 1.3 GHz frequency.

How about the you underclock in order to save battery as 1.3 quad core is not that necessary for mild usage.

200mhz is the lowest underclock i get in my experiments ,i tried 156 mhz but it didn't boots up ?

low clock means less processing power so it lags if i set both minimum and max frequency to 200mhz else it is fine[emoji23]

OK, so the device will run smoothly on ~550 MHz without loosing too much on performance and save battery also, ?

N960F maximum frequency dose not scale over 1.79Ghz

Hello, my Note 9 does not go over 1.79Ghz, this happens also with the phone set for maximum performance. Using some cpu stress tools I can clearly see that the big cores set @1,79GHz like the little ones.
Also in 3cToolbox the usage for frequencies above 1.79Ghz is always 0.
Anyone is aware of this?
Thank You Very Much,
Mauro

im sure that this isnt common knowledge, so than k you for posting this, but im sure its the kernel causing the max clock speed. are you running stock firmware?

Yes It's the stock firmware. For example now over a total of 28min @1.79hz i Just have few seconds @2,7GHz and non at the intermediate levels.
Phone is again in Maximum Performance
