And don't forget to read this LWN page
You need to configure you kernel with CONFIG_FUNCTION_TRACER enabled.

Hi Pradeep,
Seems like it might serve my purpose ... a very useful one .. But I
didn't find how to configure it in the kernel ... I mean the kernel
config option or what menu in 'make menuconfig'

Hi,
I want to log the following activities with timestamps - *as precisely
as possible* :
i.enqueuing of a process
ii. dequeuing of a process
iii. a process starts executing on cpu
iv. a process is preempted/yeilds the cpu
What is the best (precise, efficient and easy) way of doing so ?
