We have tested l3fwd-power with octeontx2 PMD, l3fwd-power disables queue interrupt even if a single packet is received on the queue. I assume you are pumping multple flows to the nic. > I am observing the below output: > */root/comms/dpdk/examples/l3fwd-power/build/l3fwd-power -l 2,3,4,5 -n 6 > --socket-mem 512,0 -w 17:00.0 -w 17:00.1 -- -p 0x3 --config > '(0,0,2),(0,1,3),(1,0,4),(1,1,5)' -P* > EAL: Detected 48 lcore(s) > EAL: Detected 1 NUMA nodes > EAL: Multi-process socket /var/run/dpdk/l3fwd/mp_socket > EAL: Probing VFIO support... > EAL: PCI device 0000:17:00.0 on NUMA socket 0 > EAL: probe driver: 8086:158b net_i40e > EAL: PCI device 0000:17:00.1 on NUMA socket 0 > EAL: probe driver: 8086:158b net_i40e > Promiscuous mode selected > POWER: Attempting to initialise ACPI cpufreq power management... > POWER: Power management governor of lcore 2 has been set to user space > successfully > POWER: Initialized successfully for lcore 2 power management > POWER: Power management governor of lcore 3 has been set to user space > successfully > POWER: Initialized successfully for lcore 3 power management > POWER: Power management governor of lcore 4 has been set to user space > successfully > POWER: Initialized successfully for lcore 4 power management > POWER: Power management governor of lcore 5 has been set to user space > successfully > POWER: Initialized successfully for lcore 5 power management > Initializing port 0 ...
