Hi Reshma, I am getting error, upon executing saying that it's an invalid core mask.
Also please let me know how you are calculating the hexadecimal bitmask for the cores. ./kni -c 0x1E -n 4 -- -P -p 0x3 --config="(0,1,3),(1,2,4)" EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 1 on socket 0 EAL: Detected lcore 2 as core 2 on socket 0 EAL: Detected lcore 3 as core 3 on socket 0 EAL: Support maximum 128 logical core(s) by configuration. EAL: Detected 4 lcore(s) EAL: lcore 4 unavailable EAL: invalid coremask Regards, Arun Raj -----Original Message----- From: EXT Pattan, Reshma [mailto:[email protected]] Sent: Wednesday, December 09, 2015 3:37 AM To: P D, Arun (Nokia - IN/Bangalore) <arun.p_d at nokia.com>; users at dpdk.org Subject: RE: Issue on Running KNI application Hi Arun, Core mask value i.e. -c value should be 0x1E in your command. Because you are using cores 1,2,3,4 so their respective bits must be set to 1 in -c value. ./kni -c 0x1E -n 4 -- -P -p 0x3 --config="(0,1,3),(1,2,4)" Thanks, Reshma > -----Original Message----- > From: users [mailto:users-bounces at dpdk.org] On Behalf Of P D, Arun (Nokia - > IN/Bangalore) > Sent: Tuesday, December 8, 2015 6:06 PM > To: users at dpdk.org > Subject: [dpdk-users] Issue on Running KNI application > > Hello, > > I am trying to run the KNI program in examples of dpdk. > > I am giving the following command and facing the error as "Cause: lcore id 1 > for > port 0 receiving not enabled". > > Please let me know if I am making any mistake at config parameters, or I am > missing something. > > ./kni -c 4 -n 4 -- -P -p 0x3 --config="(0,1,3),(1,2,4)" > > EAL: Detected lcore 0 as core 0 on socket 0 > EAL: Detected lcore 1 as core 1 on socket 0 > EAL: Detected lcore 2 as core 2 on socket 0 > EAL: Detected lcore 3 as core 3 on socket 0 > EAL: Support maximum 128 logical core(s) by configuration. > EAL: Detected 4 lcore(s) > EAL: Setting up physically contiguous memory... > EAL: Ask a virtual area of 0x200000 bytes > EAL: Virtual area found at 0x7fd603600000 (size = 0x200000) > EAL: Ask a virtual area of 0x1000000 bytes > EAL: Virtual area found at 0x7fd602400000 (size = 0x1000000) > EAL: Ask a virtual area of 0x3c00000 bytes > EAL: Virtual area found at 0x7fd5fe600000 (size = 0x3c00000) > EAL: Ask a virtual area of 0x50400000 bytes > EAL: Virtual area found at 0x7fd5ae000000 (size = 0x50400000) > EAL: Ask a virtual area of 0x29c00000 bytes > EAL: Virtual area found at 0x7fd584200000 (size = 0x29c00000) > EAL: Ask a virtual area of 0x1000000 bytes > EAL: Virtual area found at 0x7fd583000000 (size = 0x1000000) > EAL: Ask a virtual area of 0x200000 bytes > EAL: Virtual area found at 0x7fd582c00000 (size = 0x200000) > EAL: Requesting 1024 pages of size 2MB from socket 0 > EAL: TSC frequency is ~3192614 KHz > EAL: Master lcore 2 is ready (tid=3cb98e0;cpuset=[2]) > EAL: PCI device 0000:03:00.0 on NUMA socket -1 > EAL: probe driver: 8086:1533 rte_igb_pmd > EAL: Not managed by a supported kernel driver, skipped > EAL: PCI device 0000:05:00.0 on NUMA socket -1 > EAL: probe driver: 8086:100e rte_em_pmd > EAL: Not managed by a supported kernel driver, skipped > EAL: PCI device 0000:06:00.0 on NUMA socket -1 > EAL: probe driver: 8086:10d3 rte_em_pmd > EAL: Not managed by a supported kernel driver, skipped > APP: Port ID: 0 > APP: Rx lcore ID: 1, Tx lcore ID: 3 > APP: Port ID: 1 > APP: Rx lcore ID: 2, Tx lcore ID: 4 > EAL: Error - exiting with code: 1 > Cause: lcore id 1 for port 0 receiving not enabled > > Regards, > Arun Raj
