Why do I see "permission granted for interactive call " periodically after installation of this app? And is gone after I uninstalled this app.

lil fishy

Works great on LeeDroid 6.2, just seems to miss some features, like using 1 core when on standby, and when using games or bigger demanding apps it swithes to all 4 cores.
My phone now heats up much less than before on charging, current temp is 35°C.

Using leerom too and during charge temp is 23C.... And this is without this app

Sry nut your concerns are not necessary

That's just the super user output that it got supersu rights.

This appears even if you give widget locker super user rights..

Depends on your previous usage and your usage while charging.
Although battery would have to cool down to at least under 30 C when charging and deep sleep

Yes it does but once. Not repeatedly when you are using phone. Hope you read English nut

Afaik the app uses a Methode which places a prepared file /change into system to control the cores.
Probably the app checks on every startup which file /core setting is used.

Anyway I have really no concerns about this.

It appears for me when I am starting the app but nowhere else.

I think the 5th companion core already does the job of low power use on standby.

I think that's just CoreControl issuing Root Commands (which it does a lot!).
It's nothing to be worried about

Here's an example of what it's doing when those messages come up, if anyone's interested:

Here's the Root Command method (Imaginatively named, I know

)

Code:

public void DoThings(String path) {
		try {
			Process process = Runtime.getRuntime().exec("su");
			DataOutputStream os = new  DataOutputStream(process.getOutputStream());
			{
				os.writeBytes(path);
				os.flush();
				os.writeBytes("exit \n");
				os.flush();
				process.waitFor();
			}
		} catch (IOException e) {
			e.printStackTrace();
		} catch (InterruptedException e) {
			e.printStackTrace();
		} 
	}

And then I set the cores like this

Code:

DoThings("echo '2' > /sys/kernel/debug/tegra_hotplug/max_cpus\n");

Nothing fishy going on

Possibly Stupid Question

Ok, So I realize that there is a big difference with the SoC from the "HTC One X" to the Sprint version the "HTC EVO 4G LTE" the One X is quad core tegra and the EVO LTE is a dual core S4.

Ok so now that being said, could this app be used on the EVOLTE to turn a dual core to a single core for power saving?

Can't Wait to try this

My One X will arrive shortly.

This is working too on the Asus Transformer Prime (Tegra 3).

I just have one question regarding how this works. As far as I know, the Tegra 3 Chip should automatically turn off cores when not in use.

If I select 4 Cores on the app, will this lock the device on using 4 Cores always, or will it follow the normal Rules and only turn the other ones when needed?

Goku80 · May 17, 2012

i have a stupid question as well. is it not the kernel which determines which cores are off and on? i mean on the s2 the only way to do it is by installing an app that Tegrak made with his kernel. Then other kernel devs like Gokhanmoral and Simone implemented the feature in their kernels and was able to use that app to switch from single core to hotplug and two cores at all times...So my question how is this enabled if the kernel devs have not included this into their kernels yet or is this a special thing with the Tegra chip? Sorry if this sounds stupid but for me is kinda interesting to know..

many thanks for your time

Other way round if you lock it to max 2 cores than never more than 2 cores running.
When you lock 4 then it will use up to 4 cores when a heavy game is running.

All in all is that you only set the Max core number but don't change the scale behavior of tegra 3.

Great app, would be even better if we can also set maximum CPU speed for the One X. I've tried some apps from Play Store but none of them works reliably.

Also anyone know where the file controlling CPU frequencies is stored?

use no frills to control the cpu frequencies..

I doubt it, I'm pretty sure this mod only applies to the HTC One X (possibly other Tegra3 devices too). There may be a different way to do it though.

We can do it because, for some reason, the file "/sys/kernel/debug/tegra_hotplug/max_cpus" which controls how many Cores you have active isn't touched by the Android system except for when the phone boots up. So, as long as you have root, you can edit this file regardless of the kernel

ahh nicely done thanks mate.

great job you have done and using the app now

can we also use system tuner to check which cores are off and on then
