*Project summary The project goal is to support multiqueue network interface on BPF, and provide interfaces for multithreaded packet processing using BPF. Modern high performance NICs have multiple receive/send queues and RSS feature, this allows to process packet concurrently on multiple processors. Main purpose of the project is to support these hardware and get benefit of parallelism. Here's status update from last week: * bug fixes & test of "queue len, queue affinity ioctls moved to the device ioctl" Last week I had a these problems: - ifconfig shows invalid affinity value on igb(4) - SOFTRSS doesn't work, fixing - multi queue bpf is not well tested after the change I fixed these in this commit http://p4web.freebsd.org/@@195722?ac=10 Also, tested multiqueue bpf on both HW RSS NIC and SOFTRSS NIC. This is output of modified version of ifconfig: igb0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=1001bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,MULTIQUEUE> rxqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] txqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] ether 00:1b:21:53:ed:58 media: Ethernet autoselect status: no carrier igb1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=1001bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,MULTIQUEUE> rxqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] txqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] ether 00:1b:21:53:ed:59 inet 163.215.189.124 netmask 0xffffffc0 broadcast 163.215.189.127 media: Ethernet autoselect (1000baseT <full-duplex>) status: active msk0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=2c011b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,VLAN_HWTSO,LINKSTATE,SOFT_MULTIQUEUE> rxqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] txqueue len=1 affinity=[ 0:0 ] ether bc:ae:c5:3e:a6:3c media: Ethernet autoselect msk1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=2c011b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,VLAN_HWTSO,LINKSTATE,SOFT_MULTIQUEUE> rxqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] txqueue len=1 affinity=[ 0:0 ] ether bc:ae:c5:3e:a5:67 media: Ethernet autoselect fwe0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=200008<VLAN_MTU,SOFT_MULTIQUEUE> rxqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] txqueue len=1 affinity=[ 0:0 ] ether 02:1f:c6:09:e4:75 ch 1 dma -1 fwip0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 lladdr 0.1f.c6.0.0.9.e4.75.a.2.ff.fe.0.0.0.0 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet 127.0.0.1 netmask 0xff000000 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0xf nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> vboxnet0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=200000<SOFT_MULTIQUEUE> rxqueue len=6 affinity=[ 0:0 1:1 2:2 3:3 4:4 5:5 ] txqueue len=1 affinity=[ 0:0 ] ether 0a:00:27:00:00:00 Now we have rxqueue/txqueue len & affinity info, and options field shows MULTIQUEUE and SOFT_MULTIQUEUE flags.home | help
