Hi Sorry I am not sure if this is the right list to ask this question, please direct me to the correct one. thanks!
I am using Intel 82599 on Dell PowerEdge R710 which should support NUMA node, the box is running ubuntu 14.01.1 LTS , I am wondering why I get NUMA socket -1. in BIOS, the memory "Node Interleaving" is disabled by default and I am using DPDK and DPDK sees my NIC NUMA -1, but i guess it is not related to DPDK since the sysfs shows NUMA -1, any clue? # uname -a Linux pktgen 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux EAL: Master lcore 0 is ready (tid=79b78900;cpuset=[0]) EAL: lcore 8 is ready (tid=f2deb700;cpuset=[8]) EAL: lcore 15 is ready (tid=ef5e4700;cpuset=[15]) EAL: lcore 5 is ready (tid=f45ee700;cpuset=[5]) EAL: lcore 2 is ready (tid=f5df1700;cpuset=[2]) EAL: lcore 10 is ready (tid=f1de9700;cpuset=[10]) EAL: lcore 6 is ready (tid=f3ded700;cpuset=[6]) EAL: lcore 7 is ready (tid=f35ec700;cpuset=[7]) EAL: lcore 11 is ready (tid=f15e8700;cpuset=[11]) EAL: lcore 1 is ready (tid=f65f2700;cpuset=[1]) EAL: lcore 13 is ready (tid=f05e6700;cpuset=[13]) EAL: lcore 4 is ready (tid=f4def700;cpuset=[4]) EAL: lcore 9 is ready (tid=f25ea700;cpuset=[9]) EAL: lcore 3 is ready (tid=f55f0700;cpuset=[3]) EAL: lcore 12 is ready (tid=f0de7700;cpuset=[12]) EAL: lcore 14 is ready (tid=efde5700;cpuset=[14]) EAL: PCI device 0000:04:00.0 on NUMA socket -1 <======== EAL: probe driver: 8086:10fb rte_ixgbe_pmd EAL: Not managed by a supported kernel driver, skipped EAL: PCI device 0000:04:00.1 on NUMA socket -1 <============== EAL: probe driver: 8086:10fb rte_ixgbe_pmd EAL: PCI memory mapped at 0x7feb77c00000 EAL: PCI memory mapped at 0x7feb77c80000 PMD: eth_ixgbe_dev_init(): MAC: 2, PHY: 14, SFP+: 6 PMD: eth_ixgbe_dev_init(): port 0 vendorID=0x8086 deviceID=0x10fb Total number of attached devices: 1 Interface name: dpdk0 kernel sysfs output: #cat /sys/devices/pci0000:00/0000:00:05.0/0000:04:00.0/numa_node -1 #cat /sys/devices/pci0000:00/0000:00:05.0/0000:04:00.1/numa_node -1 # numactl --show policy: default preferred node: current physcpubind: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 cpubind: 0 1 nodebind: 0 1 membind: 0 1 # numactl --hardware available: 2 nodes (0-1) node 0 cpus: 0 2 4 6 8 10 12 14 node 0 size: 40317 MB node 0 free: 38699 MB node 1 cpus: 1 3 5 7 9 11 13 15 node 1 size: 32166 MB node 1 free: 30706 MB node distances: node 0 1 0: 10 20 1: 20 10 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
