I was wondering if there's a kernel that's the same as the one in cm10 but with a lower minimum frequency. I think having 384mhz as the minimum is too high.

I believe Learnkernel exp. builds have lower. Instead of 384 it goes to 192.

Just make sure you download the latest exp1 build and you should have the option to set your performance down to 192 at the lowest!

This kernel allows you to adjust the min as well.

excuse me; have question about this kernel; i couldn't post in the original thread;
by setting the min clock speed to 768MHZ & the max to 1407MHZ, How much voltage does it spend? by setting the min to 245MHZ & max to 1024MHZ how much? i overclocked to 1407MHZ , i saw more smoothness and speed; but i felt that its consuming more power!
is overclocking harmful to CPU? ( always overclocking )
Rom: MY One V RC4.0 FX

Hi
Political correct answer:
Of course OC "can" harm your device - like all OC´ing
Realistic answer:
Most One V devices can handle OCing up to 1.5 without problems
but since this may be specific to chip manifacturing there is no
guarantee that it is. Therefore before using any OC you should
test it very carefully.
And also - Of course running the chip at higher frequencies needs
more power. Simply physics .)
In "normal" daily use the difference is not big because the cpu will
not run at high frequencies most of the time. If you do things
like "heavy" gaming this is of course forcing the cpu to run faster.
To reduce the "effect" a little bit there is a kernel feature called
Undervolting (UV) with that you can reduce the voltage for
specific frequencies. Like OC this is device specific. So some
devices can run stable with more reduced voltage then others
BTW: why to you set the min frequency to 768?
This will limit that the frequency cannot go lower then that if the
device is idle. Running at 245 needs of course less power then 768
max
Thanks for the nice info, well, i heard that some users said that the best frequency for " My One V" rom:
Minimum: 768MHZ
MAX: 1407
I'm using "Set CPU" to OC
So setting the min frequency to 245MHZ will save more power, right?

Yes - especially for the time before the device can go into
"deep sleep" when beeing idle.
The only "disadvantage" is that depending on the govener that you use
there might be a small lag before the frequency scales up
Actually it depends if you notice it at all
If you use govener ondemand it should be no problem
if you use e.g. smartassV2 you might consider thinking about
using some tunables that will reduce that behaviour.

Thanks, yeah, i meant for normal activities, like checking Facebook,mail, watching movies ... So ondemand mode would be better

What is your recommend governor to integrate with your Titanium-KISS kernel and what is your favourite I/O Scheduler tweaks, for daily use & heavy gaming?
I'm using smartassV2 & i set my I/O Scheduler to deadline until now, because it's peoples favourite
Should i change it to ondemmand to gain a better performance?
Hi
Actually there is already a lot of information about your question
in the KISS kernel thread.
Especially about how to tweak smartassV2 based on "profiles"

uh, okay...i'll re-read the info once again :good:
I've been using Franco kernel for a long time now, on various ROMs. My current ROM is JBSourcery (4.1.1); I've always had this problem though, no matter if the kernel was on a milestone build or nightlies. The Max cpu and governor change almost randomly! I'll set the max cpu to 1536 or 1612 and after a few hours or a few minutes it changes on its own!
For example, I changed the CPU to 1612 max and 384 min with 'interactive' governor.
Later that day (less than an hour later) it starts lagging like crazy, so I look at the settings and it's changed to 1036 max, 728 min and the 'ondemand' governor. This happens frequently, usually after I've locked it for awhile, and reopened it. It's starting to drive me crazy!
I have "set cpu settings on boot" checked, as well as "set governor control on boot" This is happening on all the kernel versions I've tried so far, including 262, 264, 268 and Milestone5. What on earth is going on?!
dmesg or it never happened
post in franco's thread, way better chances of getting his/other users attention than here.

then its your rom thats broken, probably doesnt have the powerhal fix. some cpu control apps include the fix in the app for that reason, like the trinity kernel toolbox app. i dont think francos app includes it. or the fix could be as simple as updating your busybox.

Hi,
Just putting out a question to those that tweak their Gnex cpu settings. What minimum mhz do you use that would still provide great response and yet saves battery?
Currently I am running min cpu @ 307mhz with Trinity Kernel.

Using 230mhz on Franco no problems with signal and the phone wakes up nice and fast.
Hi i have ARHD on my phone with the XM Kernel. I was slightly suprised in the Trickster MOD app, the max clock speed is 1.3ghz. Yes i know i can OC to 1.5 but im not sure what is setting this. When i had ARHD installed with stock kernel it was showing 1.3 as default. I assume that was set by the ROM. But i installed this kernel and still has 1.3 as the default.
Also the default govenor settings for the gaming one has the boost_freq set at 1300000, which is 1.3ghz, that can be changed to 1.5 also. But surely the boost freq would be the max freq no matter if you move the slider to 1.5 in the basic controls? But i would be suprised that the gaming govenor would underclock the cpu, surely for gaming you would want the phone maxed out?
Is this expected with the XM Kernel and the ARHD? And if so, is there any things i can change in the govenor settings to make sure it performs at absolute max?
It's kernel related; Xmisters' kernels since 188 have a hard cap(1.3Ghz) by default, but using trickster mod, or another o/c apk, you can raise it to the stock 1.5Ghz(tick 'set on boot' to ensure it stays at 1.5) The best settings are trial and error, tbh, I use touchdemand/sio though smartmax seems to be the best balance.
Thanks for the answer. i can change it to 1.5 easy enough, but if you look in the govenor control, the boost_freq is is set to 1300000. If i left it at that, would it prevent the cpu from going up to 1.5?

you have sleep (lowest CPU can go), ideal freq(the speed the CPU aims for while awake), touch poke (when you touch the screen), boost (what it boosts too to prevent lag) and max (CPU flat out)
Setting the boost to 1.3 will still allow the could to run at full speed.

That makes sense, cheers. So its probably a good idea to leave it as it is then.
Hey guys,
i got a problem adjusting the cpu frequencies on my Galaxy S4 mini GT9195.
For example, i change it to 162mhz minimum and 1026mhz maximum and the smartassV2 govenor. Then that changes ramdomly to some weird frequencies automaticly and out of a sudden. Like 1458mhz minimum and maximum.
I use the cyanogenmod11 M7 rom and the f4ktion 1.5.0 Kernel (the cyanogen kernel does the same btw)
As App for adjusting i use the Kernel Tweaker, but even if i do it in the System settings its doing the same...
I did some undervolting, this stays as i set it.
I hope you guys can help me its annoying to check it every houre and see that it changed again and drains my battery

Devices using a modern qualcomm cpu, relies on two userspace daemons (mpdecision and thermald) to manage frequency and thermal throttling. So mpdecision takes care of the frequencies and cpu hot-plugging (when to engage additional cores or not), and thermald lowers the frequency if the temperature gets too high, in order to protect the cpu from overheating. This is not compatible with the frequency settings in CM or any third party app with similar functionality, as they will always override whatever you set there.

I see.. Thanks for the answer mate, so there's no way to save battery like this? It just seems sometimes that it's stuck at some frequencies...
Well, you could make a custom boot image that disables those daemons, but it could cause more harm than good.

f4ktion kernel 1.5.0 is not designed for M7. For M7 use 1.4.5.
I'm right now with nightly 0703, kernel 1.5.0, mpdecision disable and MSM Hotplug enable (performance control). With this settings that bug disapeared. 162 mhz - 1728 mhz; smartassh3; ROW.
In M7, and 1.4.5 kernel, the only governor that works with 162 mhz and don't change to 1458 mhz is the Ondemand.
