Hi, there I am using DPDK-16.11 on XL710 40GbE NIC. OS: CentOS 7.3.1611 with Linux kernel version 3.8.0-30.
I have a master process and a secondary process. When I run the secondary process with less than or equal to 4 cores, it works correctly. Such as: sudo ./program -l 4,5,6,7 -n 4 --proc-type=secondary sudo ./program -c 0x0f -n 4 --proc-type=secondary However, there will be error in the rte_eal_init if I assign more than 4 cores. sudo ./program -l 0,1,2,3,4 -n 4 --proc-type=secondary sudo ./program -c 0x1f -n 4 --proc-type=secondary EAL: Cannot mmap device resource file /sys/bus/pci/devices/0000:02:00.0/resource0 to address: 0x7fff65bfc000 EAL: Error - exiting with code: 1 Cause: Requested device 0000:02:00.0 cannot be used Anyone knows why this happens? Thanks a lot, Kai Zhang
