Hi,
 
I wanted to track down memcpy operations of vari= ous user applications/lib or kernel modules.
In one of the scenarios there are too many memcp= y operations used in our platform.
And we wanted to track which appln/lib and kerne= l modules doing memcpy and of what size.
 
If anybody is aware of any utility please let me= know.
 
Or,
please let me know how to track memcpy from kern= el space may be using some kernel module.
 
 
Thank You!
With Regards,
Pintu
