Question about ftrace about gpu-dpdk
It seems Nsight Systems default ftrace setting is not enough for tracing dpdk (under rx_pkt_burst/tx_pkt_burst).
For example, I want to monitor gdrcopy timing.
Is there any instruction?

It seems using rdma sniffer is one of solution. tcpdump can use this feature since libpcap 1.9 or later supports rdma sniffer.
