Tegra 3 CPU monitor

Is there a CPU monitor like the one used in this video: http://goo.gl/aSZpq?
Be nice to see when the companion core is being used...

There is an app called tablet cpu usage app doing maybe the same.

He would have had to buy the pro version :/
Since I don't use Google checkout I didn't test it myself

Ops sorry

It works but doesn't see the 5th core. Some of the app's UI displays properly only in landscape (some bits are squished in portrait).
Some screenies...

Yes 5th core isn't seen by the system itself so not an issue of the app.

Yeah - can see when companion is used as the 4 cores show no use...

can you give the market link or the app's full name

U`ll never see the companion core.
It`s invisible to Android OS
management is on Nvidia level

the companion core only works wen the screen is off, It's used for background tasks which doesn't need the quad-core.
It's controlled by hardware so even Android can't see it

so what they using in the video? As that can see it?

My guess is that its an app designed by Nvidia that has the ability to call the companion cores usage..

Android OS never sees it, but I've been digging through nvidia's tegra kernel repo[1] and the kernel definitely knows about the extra core. But it doesn't get reported over any of the regular performance monitoring interfaces.
However arch/arm/mach-tegra/sysfs-cluster.c[1] defines a sysfs interface than can report if the low power core/cluster or the high performance cluster is in use, tweak a few parameters and even force it to switch between clusters.
Reading /sys/kernel/cluster/active will report the currently active cluster (LP or G). writing 'lp' or 'g' will force it into one of those modes.
You can also find various stats in /sys/kernel/debug/cpuidle/lp2 and /sys/kernel/debug/tegra_hotplug/stats.
I've only skimmed some of the code, and so far I'm not sure if the completely automatic switching from the low power core to the fist core that nvidia brag about actually exists. Some comments in arch/arm/mach-tegra/pm-t3.c suggest that the at least the first generation of Tegra 3 chips have bugs and don't quite switch the entire cpu state and implement some workarounds.[3]
Anyway back to the main topic, I'm guessing that someone could hack together a cpu monitor that polled /sys/kernel/cluster/active and assigned the activity of the first core to either the companion core or the first core depending on which cluster is active.
As a new user, I can't post links, but here are some urls you can copy/paste

Based off above posts saying that android itself is not aware of the extra CPU...
I have not rooted my HOX yet however i have installed SetCPU to monitor clock speed of the CPU.
To my supprise, it seems that the lowest clock you can set is 51Mhz...
Im not sure if this is a bug with setcpu/stock rom but to me if it is at 51mhz then that would be the +1 core.
The lowest i can monitor my phone go to when i am watching SetCPU is about 100mhz

U`r getting close......
The 4 cores have a min clock of 100
The 51Mhz is indeed the companion core cause the 4 cores never NEVER drop below 100Mhz

how did you manage to get it to install on your HOX ? I just bought it but the download don't start ! tryed through wifi & 3G, nothing changes.
It seems that google play store is blocking the download for non tablet user, although it say it's compatible with the HOX...
0.99 $ spend through the window....

I was able to download it from market but uninstalled within my 15min window since it's not optimized for the one x screen + quicksystem Info & CPU spy app can do the same with more functionality
Sent from my Leedroid powered HTC One X

I finally managed to install it on my oneX but I'm disapointed to see that the companion core seems to be never used.
I was expecting to see the four cores down to 0% in numerous low usage case but it NEVER get down to 0% even when sitting on the desk and doing nothing
in the vid which have been posted in the first post, you can clearly see that the companion is activated at least 90% of the time.
I don't know what to think about that, is the companion core included in the four cores stat through Tablet CPU Usage Monitor, or is the companion being never used ???
Also, I have read around here that the GPU actualy doesn't render 2D things (even the desktop), so it might explain why the companion is never activated...

[Q] N3N Games & Apps Performance Issues

Hi there
I have my Note3 Neo for a month now and it runs superb, love this device. However.. there are few 3D Games that glitch during gameplay
Beach Buggy Blitz- Starts up fine but after a while I start to notice game Glitches, The checkpoint clock and the Boxed graphics on the sides don't act as they should be. There other parts of the game that acting the same way.
Dungeon Hunter 4- (Great Game) Starts Fine, After a while all the characters lose their characteristics.. face.. sword details.. armor details.. etc..
PlayStation® All-Stars Island- The Game itself runs fine, but on the main menu (the Island) it like the 3D is broken (pieces disappear and appear again).
Other 3D Games like Kritika: Chaos Unleashed, Dead Space, Dark Avenger, Dead Triger run smoothly.
Just want to know if there is anyone else out there having the Same Problems or its just me.
P.S i read about Modern "Combat 5 not working" If thats the case Big.Little Possessor is there a way to fix this?
Thanks

Although the reviews compare it with snapdragon 800 and they say the cpu is on par and gpu os on par with adreno 320...however I have noticed games were much smoother on my Nexus 4. At SOME point on note 3 neo games do stutter.

Maybe neo is hexacore so that is the reason some games lag.

Is there a way to disable/enable the dual core possessor via terminal emulator or with scrip? I tried using couple of apps but some didint work and other were made for quad core devises and showed only 4 cored...

its definately better than quadcore....i mean A15 dual core processor definately add a huge pump to A7 quadcore processor.....

I know that hexacore is better than quadcore... I just want to know if there is a way to disable/enable them to see if the games will work better without lag or glitches or if its because of the "Big.Little" possessor

I think u can control ur CPU :laugh:
Hello Guys :laugh:
This is my first ever post (or reply :silly on XDA :laugh: . I own a N3N (SM-N750 INDIAN VERSION). I bought this phone like a week ago, and i am enjoying it (except for the KNOX ). I rooted it the second day :laugh: and was playing around with it as i previously had a Galaxy Y :good: . I installed the same app (System Tuner) i used in my SGY to manage all the root level settings. I installed it on my N3N and first went into the CPU section and it actually displayed 6 CPUs (from CORE0 to CORE5) and also the first 4 cores which are based on Cortex A7 were clocked at 1.3 Ghz and the last 2 cores ie. CORE4 and CORE5 were clocked at 1.7 Ghz. And guess what it had all the options like configuring the speed of the cores, forcing them on or off and also changing governors (but i say dont change governors it freezes the phone then u have to pull the battery :laugh: ) and it had couple of other option to use on a rooted phone like FS Trimmer, Build prop tweaks (it works on mine no bootup issues ) entropy fixer (like seeder i think) sd card cache size, oom fixing, and all the other things u want on a rooted phone :laugh: . However i was not able to find any option to control GPU freq.
In short it was the best app I found till now to control various aspects of your N3N including CPU. :victory:
As I m a new member i cant post links i think :silly: just google "system tuner" and you will get it :laugh:
As i mentioned earlier if it is my first post, if I did any mistake please forgive me :laugh:

Have a look at this App to change GPU speed

FYI just tried the GPU_OC up to see if it will do any difference to the games.. But now i get an "Unfortunately, System UI has stopped" error on the long press of menu button (recent apps). P.S i own an N3N 7505.
just saying as heads up..
The error was caused by the secure settings the apps asks you to download..

I belive custom kernel is needed for that kind of stuff

[Q] Galaxy tab S 8.4 weird CPU-Z info

i just noticed something else wrong with my galaxy tab s 8.4 the CPU-Z info "http://i.cubeupload.com/3LpKj0.png" the exynos 5420 suppose to be with 4 slow cores at 1.3 and 4 fast cores at 1.9 but on this info from CPU-z it shows them all as 1.9 somehow , and also here "http://i.cubeupload.com/vUgZnP.png" it shows the screen dpi 320 instead of 359 . is it the same on your device as well ? can you share any screenshots or info thanks im using CPU-z 1.1 btw

Same here. SM-T700

My T800 10.5 Exynos 5420 shows the screen at 320dpi and the cpu as A7 as 1.9ghz and A15 as 1.9ghz
At least cpu-z show my cpu as having 8 cores, other apps i have tried only show 4 cores.
John.

oh so im not the only one seeing this >< the DPI thingy is fine guys i was checking some other app it was showing density 320 "wich is the DPI on cpu-z" and then the screen DPI as 359.64 so dont worry that part is correct , but why it shows both ARM cpus clocked at 1.9 i dont understand :S and yes mine shows 8cores too " http://i.cubeupload.com/IySEjH.png " here is the screenshot share your screenshots too if possible

Below is a link to my 10.5 cpu-z screenshot.

5\6 cores is stopped

Hey everyone,
Recently my device is very slow. I downloaded the app CPU-Z and my surprise that 5 of 6 cores are not working.
Notably, the device is not on battery saving mode.
H815 Android 5.1 no rooted.
Does anyone know what the problem is and how to fix it? Because it is nearly impossible to use the device.
Thanks

Cores 5 and 6 is for Big Cpu and they will enable only when it need
If you are sure that it not work try Download Kernel adiutor then in cpu settings click on the checkbox cpu cores

need some help over here with n7505 hexa core edition

Hello, did someone got the N7505 (hllte) hexa core (6-cores) ? the 2 big cpu cores comes dead when flashing a custom rom(cm or aicp or bliss pop all same), open developer options and enable "show cpu info" , you will see only 4 cores running, idk maybe I'm wrong but did someone noticed ?
