I'm just now getting into which governors do what. I've been researching them online and have a general idea of what each does.
That being said, which governors are made specifically for dual core processing? I have seen that hot plug is made for this. Any others?

Morning all, I am wondering settings people use with setcpu on their phones. Mine has always been set to ondemand, but wondered what the other ones do and are there any benefits?

Depends on the kernel actually... current trend is leaning towards ondemand, and so am I... I tend to put it to performance for Quadrant tests to eliminate lag, but that seems to be it...
Loving smartass governor since my battery stays generally the same when screen is off. Kernel has to support it though.

Just curious but is there a way to disable dual core here in the epic world?? I know we had scripts in 3d land but just wandering if there was a script here somewhere

Why would you even want to do that?

Just curious bro that's all also I don't use my phone for high end stuff so I assume with dual core its just eating more battery than single core.......just curious that's all man ....maybe ill get an extended cause my battery life is just ok at the moment

Get cpuspy from google play and see how long your phone is in deep sleep. You might have a wakelock or misbehaving app.

Actually, it does the opposite. Because the second core allows it to finish processes faster, it sends it back into sleep quicker as well. The amount of power used by both cores in the completion is most likely less than for a single core to do the same. I have seen overclock kernels on dual core devices that allow for independent control over each core. It requires source, I'm sure.

Intel is also releasing a single core mobile processor,though I doubt it has any influence whatsoever over this article.

I gathered that they feel that chip manufacturers have been lazy in optimizing the utilization of multiple cores. Speaking from someone who has developed on systems specifically designed by Intel, I can attest that they put great effort into maximizing efficiency. Even in their software, the Intel compiler suite is very nice.
Agreed.
There is an application in the market that shows when the second core runs. It only kick on every once and a while when needed..

You can use CPU Editor, It's a script that allows you to force dual core and allows a lot of customization. For instance you can run different frequencies on each core along with different govenors and so on, could be great for saving battery life too.
If you have a dual core processor in your Windows 7 computer and one of the processing cores is disabled, you have the ability to make both cores work again. Utilizing both processing cores instead of just one will substantially increase the processing performance of your computer, which will translate into faster operations.

Root your phone. Download system tuner pro from the app store got to Cpu and change the governor to performance instead of on demand... This will use a lot more battery tho.

I actually wouldn't recommend that, in some cases performance is the better govenor for performance but I heard the S3 or the S4 processor is actually optimized for the ondemand govenor. I did some tests and I noticed that they scored pretty close to the same in the benchmarks department, I noticed that the S3 gets hot when using the performance govenor and then it starts to lag here and there but I did not experience this with the ondemand govenor.
OnDemand:
Scales CPU according to the processing needs of the programs running which saves power and is still snappy as ever.
Performance:
Locks the CPU at the top frequency regardless of processing needs which drains battery and can make the S3 insanely hot.

If you read ops request... He wants to know how to make both the cores work at the same time... And I gave him the right answer regardless of what it does to the phone he wanted to know how to do it and I answered.
Now would I recommend having both cores on at all times absolutely not... Phone drains the batter and gets pretty hot.

I never said you didn't give him the right answer I was just trying to give him a bit more info on the performance govenor.

Naturally the second core will come on when it needs to based off the type of governor set. As said before performance governor locks at Max. SmartassV2 does not have smp so the second core never goes offline. Simply turning on the second core really won't give you a noticeable difference in performance.
But using root explorer or terminal emulator, setting
/sys/devices/system/CPU/CPU1/online to 1
Then change same files permission to read only will yield an always active second core.

A friend of
Mine at my local AT&T parrot store told me the new Gs4 will have eight processors and a 12mgb camera anybody hear the same??
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Well the news is an eight core processor is likely...actually its gonna be two 4-cores...one at 1.8ghz for higher end performance and the other at 1.2ghz and can swap to this one for most daily use to save battery..and I believe a 13mp rear camera..all if this is officially still speculation but looks quite possible
Sent from my SGH-I747 using Tapatalk 2
Not all the eight cores simultaneously - so its essentially not a octa core processor - $ at a time . Either 4*cortex a15 for performance oe 4*cortex a7 for efficiency/battery life . Moreover your friend at at&t is just another regular tech blog vsitor - this is a relatively old news not something he found out/leaked to you
He didn't leak anything to me we were just talking about when the new phone would be out. I'm excited about it I'll be ready for an upgrade about the time it comes out.

Id like to know how he knows what itwould be....I call bull s**t
I think i read it will have a 13 MP camera.
Wouldn't 8 individual processors melt the phone? Lol

My S3 was getting really hot after rooting so I decided to try undervolting. I was able to under volt each clock speed by -100mv, and my device hasn't seen any performance issues, runs cool, and battery lasts way longer! What do you guys keep you voltage settings at?

It doesn't matter what other people UV since all devices are different. I can reach -125 all steps (haven't tried farther) but some others can barely do -25. It's just how their device is built.

I understand. I'm just wondering what people are running at

The reason I personally don't do both under clocking and over clocking is that the phone itself isn't made for that. I personally don't know what this phone can handle. I have seen people under clock and over clock phones and have it work while some people have phones that can't handle much at all especially the refurbished ones. My S3 handles it well but I only tried it out once. That's my feeling on the subject. If you do do either undervolting, under clocking or over clocking just remember to do it responsibly and not put it to highest power and leave it there.
