CLInfo on Nexus 4 phone

Recently bought Nexus 4 phone for the 4 cores and OpenCL support.

So wanted to do something on this phone & found Rahul Garg is doing some R&D on the Nexus devices.

So take the code from there and modified it include more information for getting extra details from Nexus phone.

Here are screen snapshots for CLInfo for Nexus 4:

Here is the extra information that I got from 'adb logcat'.

I will post the code for the above shortly.

Special Thanks:

• Rahul Garg for the base code  for generic way of getting data from .so files using dlsym approach
• University of Bordeaux for getting extra CLInfo details
