[Q] Single or Dual core ? Mystery SOLVED. - Motorola Droid RAZR

Hi,
I like to verify the CPU spec of Motorola Droid RAZR XT910. From the info I collected, I am quite not sure if the CPU is dual cores or not.
You use console using ConnectBot or adb shell command from PC.
Code:
$ cat /proc/cpuinfo
Processor : ARMv7 Processor rev 3 (v7l)
processor : 0
BogoMIPS : 598.90
Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x1
CPU part : 0xc09
CPU revision : 3
Hardware : mapphone_CDMA
Revision : 0000
Serial : 0000000000000000
For the real SMP system, it should shows,
processor : 0
and
processor : 1
Code:
$ cat /proc/version
Linux version 2.6.35.7-ga671bf6 ([email protected]) (gcc version 4.4.3 (GCC) ) #1 SMP PREEMPT Tue Oct 18 14:45:37 IST 2011
OS Monitor apps, from Market, also shows single core.
The kernel has the SMP supports, but, the CPU doesn't have more than 2 processors. Is there other way to verify it or did I missed something.
Thank you.
Update: 2011-12-22
Yes, RAZR has dual cores CPU, the kernel and OS are supports both cores. The mot_plug will add the additional core, when needed.

It's dual-core, at least it's written everywhere. As the cpecs says it has TI OMAP4430, which is dual-core processor called "Dual-core ARM® Cortex™-A9 MPCore™ with Symmetric Multiprocessing (SMP)".
I don't know what it means exactly, but sounds fair enough for me.

Yes, there are 'Dual Core' everywhere, in documentation or during booting up the phone.
Based on my experiences, using GNU/Linux in SMP multi CPUs or multi-cores cpu server platform, since 1997 , we need hw, kernel, OS and sw to take the advantage of all the CPUs available.
In this case, the kernel is SMP capable, but the CPU hw is not being seen as SMP cpu by the kernel. So, I am not sure, if Android is running on both cores efficiently. It is similar situation running MS-DOS on 6 cores CPU, Core-i7 or AMD Phenom X6, which only 1 core is being use by the OS.
If Android is running on 1 core, in RAZR, then, imagine the full potential when running on both cores.
Thank you.

Could some Devs look into it??
This was my fear for all the phones that claimed to be "Dual-core"...
Here in India we get the XT910...and this clearly now scares me...

Based on document and specs, RAZR has the dual cores cpu. But, how much. efficiently being implemented in the current stock kernel.

This is $ cat /proc/cpuinfo of my Asus eePad Transformer TF101.
Code:

That's what supposed to be looks like.

Yes it is DUAL core but second core dynamically up and down by motorola CPU hotplug driver.
Look at http://forum.xda-developers.com/showthread.php?t=1367255

Thank you for the clarification. Yes, RAZR has duai cores cpu, and it's kernel supports it.
Here is my clarification.
1) Open Connectbot and access to lacal
2) $ cat /dev/urandom > /sev/null &
3) cat /proc/cpuinfo
4) fg Ctrl-C # to kill running process cat /dev/urandom
Now, it shows both cores information.
Code:

[Q] Possible paranoia....

Got my SGSII yesterday and happily rooted it via Supercurio's kernel and restored apps, data etc.
Just out of interest, I ran quadrant and scored around 3000 which I suppose is so-so
However, the paranoia comes in when I look at the CPU info in Quadrant which shows:-
Name : ARMv7 Processor rev 1 (v7l)
<snip>
Cores: 1
Architecture: 7
<snip>
I'm going to hazard a guess and put the single core reading down to misreporting by Quadrant, but you never know....
Any thought?
Regards
Mouse
That most be some mistake ARMv7 Processor rev 1 (v7l) is an "old" processor.
Droid.droidx and HTC incredible got it . And I doubt it scores over 3000 in quadrant.
No, it's not old. ARMv* mean architecture of the ARM CPU. ARM11 mean model or so. ARMv7 is last generation, don't worry. For more info look for ARM on Wikipedia.

1. MOTOROLA SHOLES – DROID

2. HTC INC – ADR6300

3. MOTOROLA SHADOW – DROID X
Maybe its not OLD but not comply new either.
Firmware: 2.1-update1 Processor: ARMv7 Processor rev 2 (v7l) System RAM: 476 MB
And the paranoia ramps up a notch........
My "Android System Information" app gives the same CPU architecture.
Has anyone else tried this in Quadrant etc???
Btw, "About Phone" in settings gives:
Model Number: GT-I9100
Baseband Version: I9100XXKDJ
Build number:GINGERBREAD .XWKE1
The kernel is Supercurio's

stock orange no kernel downloads or anything gives me:
Name: ARMv7 Processor rev 1 (v7l)
Current freq.: 200MhZ
Max Freq.: 1200MhZ
Min Freq.: 200MhZ
Cores: 1
Architecture: 7
and so on.. is this quadrant misreading the processor as only 1 core or not detecting the other core, or is it that we have only been sold 1 core and samsung have lied to us? my box says dual core and I want it
Being a non-techie and not wanting to stoke paranoia further, I found some stuff on a discussion page that implies that the second core only kicks in when intensive activity requires and therefore may not register...

hi boys and ladies( if any ).
I connect my sgs2 to the computer in debug mode and running ADB with the*cat /proc/cpuinfo
*command, I was presented with the following info:
Code:

BogoMIPS : 1592.52*

Hello.
If u check with ADB or Android System Info you have info Core: 1 ... but when u check with Quadrant Standard Edition application you have Core: 2
I think everythink is OK and problem is in application.
The 2nd core is hotplugged in and out when needed so many not be always there.

Xperia S: Is an ARMv7 or an ARMv7 NEON?

As title says, i cant find if our processor is an ARMv7 or ARMv7 neon (yep, its ARMv7, but not sure if neon or not)
I need this info just for downloading MX Codecs, there are 2 different versions, one vor ARMv7 and other for the neon ones...
I think it's neon

no.. XS has 2x Scorpion. scorpion is based from cortex A8 but has features similar to A9.
and not all cortex A9 are neon. nvidia didnt put neon instruction in their tegra 2.
add:
and for answering the q. yes, xs's cpu has neon instruction
/proc/cpuinfo should tell you everything you need to know

[Q] Custom ROMs for Navcity NT-1710?

Hi, I've been looking around for a while for a custom ROM for my Navcity NT-1710 tablet without much luck.
I came across this thread for CM10 for Allwinner A13, which my tablet supposedly has, but upon further inspection on the thread for CWM, it says the "Hardware" in CPU info should be either "sun4i" (A10) or "sun5i" (A13), while my device returns this from ADB:
Code:
[email protected]:/ $ cat /proc/cpuinfo
cat /proc/cpuinfo
Processor : ARMv7 Processor rev 0 (v7l)

Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3

CPU variant : 0x3
CPU part : 0xc09
CPU revision : 0
Hardware : WMT
Revision : 0000

Does anyone have any idea whether I have another processor (and the company lies to its customers), or this could be some sort of misreading and I can still install CM10 normally? Thank you.
I’m looking for a custom ROM too, but without lucky....
I'm even thinking that I should make one, but without CWM it's futile.....
