Hi,

PCIe packets are bus requests. They merely say "write this into memory address X" or "send me a packet containing the data at address Y". As far as I know, there is no "sniffing mode" in any of the existing processors, that would give you the packet's content. Rather, they execute the request.

The solution for this is a packet sniffer, but as far as I know (again), this is expensive equipment. So what most of us end up doing, is just getting it right, without actually checking the packets on the wire.

If someone knows about an affordable solution for capturing packets on the wire, please post below.

Regards,
Eli
