Hi I am trying to run DPDK 2.2 example application "l2fwd" with valgrind and run in to the "Segment Sanity check failed" error. I tried with standard valgrind-3.10 and the modified one ( https://github.com/bisdn/valgrind-hugepages) and run in to the same issue
Does anyone has any suggestions? Following is the error log ------------------------------------------------------- ~# valgrind /home/user/l2fwd -c 0x00ffffff -n 2 -- -q 10 -p 0xffffffff ==2002== Memcheck, a memory error detector ==2002== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==2002== Using Valgrind-3.13.0 and LibVEX; rerun with -h for copyright info ==2002== Command: /home/admin/l2fwd -c 0x00ffffff -n 2 -- -q 10 -p 0xffffffff ==2002== ==2002== Warning: set address range perms: large range [0x82f000, 0x20bb5000) (defined) 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: Detected lcore 4 as core 4 on socket 0 EAL: Detected lcore 5 as core 5 on socket 0 EAL: Detected lcore 6 as core 6 on socket 0 EAL: Detected lcore 7 as core 8 on socket 0 EAL: Detected lcore 8 as core 9 on socket 0 EAL: Detected lcore 9 as core 10 on socket 0 EAL: Detected lcore 10 as core 11 on socket 0 EAL: Detected lcore 11 as core 12 on socket 0 EAL: Detected lcore 12 as core 13 on socket 0 EAL: Detected lcore 13 as core 14 on socket 0 EAL: Detected lcore 14 as core 0 on socket 0 EAL: Detected lcore 15 as core 1 on socket 0 EAL: Detected lcore 16 as core 2 on socket 0 EAL: Detected lcore 17 as core 3 on socket 0 EAL: Detected lcore 18 as core 4 on socket 0 EAL: Detected lcore 19 as core 5 on socket 0 EAL: Detected lcore 20 as core 6 on socket 0 EAL: Detected lcore 21 as core 8 on socket 0 EAL: Detected lcore 22 as core 9 on socket 0 EAL: Detected lcore 23 as core 10 on socket 0 EAL: Detected lcore 24 as core 11 on socket 0 EAL: Detected lcore 25 as core 12 on socket 0 EAL: Detected lcore 26 as core 13 on socket 0 EAL: Detected lcore 27 as core 14 on socket 0 EAL: Support maximum 128 logical core(s) by configuration.
