Dear Muhammad,
thank you for your help!
I've now tried to run
sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen -l 5-8 -n 3
--file-prefix pg0 --proc-type auto -b 06:00.0 -- -P -m "1.0"
and then
sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen -l 0-4 -n 3
--file-prefix pg1 --proc-type auto -b 06:00.1 -- -P -m "1.0"
but I keep receiving the same error (see below)
in the output text I find for both cases:
EAL: Auto-detected process type: PRIMARY
so I tried to set --proc-type secondary in the second command
I first received an error suggesting "It is recommended to disable ASLR
in the kernel", which I did with "echo 0 | sudo tee
/proc/sys/kernel/randomize_va_space"
now I receive the following error in the second command with --proc-type
secondary
EAL: Detected 32 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/pg1/mp_socket_12222_2a4c8375d5acf8
EAL: failed to send to (/var/run/dpdk/pg1/mp_socket) due to Connection
refused
EAL: Fail to send request /var/run/dpdk/pg1/mp_socket:bus_vdev_mp
vdev_scan(): Failed to request vdev from primary
EAL: Probing VFIO support...
EAL: Could not map memory from primary process
EAL: FATAL: Cannot init memory
EAL: Cannot init memory
any further suggestion ?
thank you
Stefano
