Multithreaded kernel module and time function in kernel space

taufique71 · 10-18-2012, 07:56 AM

For my work I need to write a kernel module that would run in two separate threads. One will enqueue and dequeue data and other will free the queue if no data is enqueued or dequeued for a certain amount of time. But because of being new to kernel module programming I don't know how to write multithreaded kernel module and how to use functions like <time.h> in standard C. I need some help in this regard. Tutorial links will but if anyone can figure me the way out to do these two tasks then it will be best.

Thanks in advance.

Best source of info for writing any kernel code is:
http://lwn.net/Kernel/LDD3/
You should at least glance at every chapter to get an overview of what kernel functions are available.
Chapter 5 will tell you about locking, which you need to do when multiple kthreads can access the same data.
Chapter 7 has info about the time functions.
