Hi all, When I have core 0 in the uhd.conf file all is well and benchmark_rate works as expected. When core 0 is removed from the conf file below, the benchmark_rate call hangs.
> [use_dpdk=1] > dpdk_mtu=9000 > dpdk_corelist=0,17,31,79 > dpdk_num_mbufs=4095 > > [dpdk_mac=40:a6:b7:b0:5e:81] > dpdk_lcore = 31 > dpdk_ipv4 = 192.168.13.1/24 Here’s where the system hangs when core 0 is removed from the list. Any ideas why this could be happening? > /home# /usr/lib/uhd/examples/benchmark_rate --rx_rate 122.88e6 --rx_subdev > "A:0 B:0" --rx_channels 0 --tx_rate 122.88e6 --tx_subdev "A:0 B:0" > --tx_channels 0 --args > "addr=192.168.13.13,mgmt_addr=192.168.12.12,master_clock_rate=245.76e6,use_dpdk=1" > > [INFO] [UHD] linux; GNU C++ version 11.4.0; Boost_107400; DPDK_21.11; > UHD_4.6.0.HEAD-0-g50fa3baa > EAL: Detected CPU lcores: 96 > EAL: Detected NUMA nodes: 2 > EAL: Detected shared linkage of DPDK > EAL: Multi-process socket /var/run/dpdk/rte/mp_socket > EAL: Selected IOVA mode 'PA' > EAL: No available 2048 kB hugepages reported > EAL: VFIO support initialized > EAL: Probe PCI driver: net_ice (8086:1592) device: 0000:98:00.1 (socket 1) > ice_load_pkg_type(): Active package is: 1.3.28.0, ICE OS Default Package > (double VLAN mode) > EAL: Cannot open /dev/vfio/141: Device or resource busy > EAL: Failed to open VFIO group 141 > EAL: Requested device 0000:b1:00.1 cannot be used > EAL: Cannot open /dev/vfio/142: Device or resource busy > EAL: Failed to open VFIO group 142 > EAL: Requested device 0000:b2:00.0 cannot be used > TELEMETRY: No legacy callbacks, legacy socket not created > ice_set_rx_function(): Using AVX2 OFFLOAD Vector Scattered Rx (port 0). > ice_set_tx_function(): Using AVX2 OFFLOAD Vector Tx (port 0). > Thanks, Victor
