Yeah, I think as far as formulation goes, it fits in nicely as a producer consumer problem, but there might be more to it. As far as queue locking goes, since I am talking about packets, I can just use the skb_(de)queue and other functions in the kernel API, which take care of locking? I am not sure if semaphore is the right way, especially when you are talking about having to use the function to process something like 2000+ packets per second. So, I was thinking a tasklet might be the best way, also since I expect to have not more than one instance of myDeliver() at any time? Once again, I have no experience here, so could be very wrong. Would appreciate any kind of advice, even if not directly relavant. -- Chandrakanth Chereddi. ECE-UIUC. -- Kernelnewbies: Help each other learn about the Linux kernel.
