Thanks for the suggestions! But I might ask several specific questions, as I can't find the answer in those documents, to give myself a quick start if that's okay. Pointing me to the files/functions would be good enough. Any explanations are appreciated. My purpose is to hack it with different scheduling policy with real-time and predictability consideration.
- Where/How is the packet scheduler implemented? How are packets from multiple queues scheduled? What about scheduling packets from queues in different address spaces? - I noticed the new support of concurrency of multi-processes in the archive of this mailing list. Could you point me to the code that implements this? - Also another related question -- where/how is the preemption/context switch between packets/queues implemented? Thanks in advance!
