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 ? Currently I am doing the following: I am using jprobes for enqueue_entity and dequeue_entity functions, to log the events. For logging context switches I have used kprobes to put a printk statement in schedule() function of kernel/sched.c before the statement that increments the context switch counter of the runqueue. -- Regards, Sukanto Ghosh -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
