In one of the scenarios there are too many memcpy operations used in our platform. And we wanted to track which appln/lib and kernel 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 kernel space may be using some kernel module. Thank You!
