hi all, is it possible to write a user space code to calculate the context switch time of a process ? I mean , how can the user space code know about the working of the scheduler? Is there any system call API to interact with scheduler or something other to interact with , regarding this problem? -- ........................ *MOHIT VERMA*

Do check the function tracing framework in the Linux Kernel. Links: * http://lwn.net/Articles/322666/ * http://lwn.net/Articles/290277/ sched_switch is the tracer you're looking for. -- Vimal
