Hi, I have a 82599ES that functions well on linux (i.e. ixgbe). However, when binded to dpdk 100% of the received packets are counted as missed (using testpmd as well as my own stable application), and non arrive to the application.
I wonder what can be the reason. Why does it functions well on linux but not in dpdk, what can be the reason that the polling rx app doesn't actually read from the device. I'm using dpdk 16.11. ubuntu 16.04 hp g9 This is the interface: 07:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Physical Slot: 2 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+ Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort+ >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 47 Region 0: Memory at f8100000 (64-bit, non-prefetchable) [size=512K] Region 2: I/O ports at 6000 [size=32] Region 4: Memory at f8200000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: igb_uio Kernel modules: ixgbe The only patch I currently have is forwarding the traffic to an internal VM and running the dpdk app in the VM, but it is not optimal at all. Thanks.
