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.

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:
Processor : ARMv7 Processor rev 3 (v7l)
processor : 0

The missing core's mystery solved.

Hello all, I'm trying to cofirm for sure (before buying a device) which versions of the Galaxy Tab product line support ARM NEON instructions. These are the SIMD instructions implemented by the ARM architecture.
From searching around the web I'm guessing:
- Galaxy Tab 7" - Does supports neon (it's a Cortex A8 which always supports neon)
- Galaxy Tab 10.1" - Does _not_ support neon (it's a Cortex A9 which optionally supports neon. This device I have and /proc/cpuinfo doesn't report neon support I guess because it's a Tegra 2 SoC whose Cortex A9 implementation does not have neon suppot)
- Galaxy Tab 2 7" - Does support neon (it's a Cortex A9 which optionally supports neon. The SoC in the device is reportedly an OMAP 4430 whose Cortex A9 implementation reportedly supports neon)
- Galaxy Tab 2 10.1" - Does support neon (it's a Cortex A9 which optionally supports neon. The SoC in the device is reportedly an OMAP 4430 whose Cortex A9 implementation reportedly supports neon)
Can anyone confirm or deny any of these? If you have one of these devices can you cat /proc/cpuinfo and check for "neon"?
Thanks.
tegra2 only supports up to vfpv3-d16

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

BogoMIPS : 2400.32
Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3

CPU variant : 0x3

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.....
