PCIe "routing"

Postby Guest » Thu Nov 24, 2016 5:25 pm

Hi, thanks for your article it is usefull.
Could I suggest to add details about these points, for example when cpu write data on device memory.
- How pkt is routed to the endpoints?
- How PCIe switch are configured to be able to know where pkt with that destination memory address has to be sent?
Thanks for your help

I suppose you'll find the answer is this thread:
