[dpdk-dev] Issue while running test/testpmd applications
Hi, #2 - It depends on the platform that testpmd is running on. If it ran directly on top of the hardware then usually you have fixed lcores. For example, in Linux, you can call "nproc" to check how many cores are available. Make sure you have sufficient number of cores and set the core mask appropriately.

[dpdk-dev] Issue while running test/testpmd applications
Hi, I am trying to run the test and testpmd applications with dpdk-1.5.0r1, using tools/setup.sh I see two errors in EAL. Can someone please help where I am going wrong. 1. The test application panics with the following log. EAL: Master core 0 is ready (tid=b74b5800) EAL: Core 7 is ready (tid=733fab40) EAL: pthread_setaffinity_np failed PANIC in eal_thread_loop(): cannot set affinity 5: [/lib/i386-linux-gnu/libc.so.6(clone+0x5e) [0xb75a901e]] 4: [/lib/i386-linux-gnu/libpthread.so.0(+0x6d78) [0xb7671d78]] 3: [i686-default-linuxapp-gcc/app/test(eal_thread_loop+0x284) [0x80b9e24]] 2: [i686-default-linuxapp-gcc/app/test(__rte_panic+0x5c) [0x804edbb]] 1: [i686-default-linuxapp-gcc/app/test(rte_dump_stack+0x1c) [0x80bb92c]] EAL: Core 2 is ready (tid=75bffb40) 2. I cant see lcores other than 0. How can I configure more than 1 lcores? Option: 11 Enter hex bitmask of cores to execute test app on Example: to execute app on cores 0 to 7, enter 0xff bitmask: 0xff Launching app EAL: Cannot read numa node link for lcore 0 - using physical package id instead EAL: Detected lcore 0 as core 0 on socket 0 EAL: Skip lcore 1 (not detected) EAL: Skip lcore 2 (not detected) EAL: Skip lcore 3 (not detected) ::: EAL: Skip lcore 63 (not detected) EAL: Setting up memory... EAL: cannot open /proc/self/numa_maps, consider that all memory is in socket_id 0 EAL: Ask a virtual area of 0x2097152 bytes Any help is greatly appreciated. Thanks, Surya
