Hi all, The l2fwd sample application starts failed in my environment with 90000 2M hugepages set up. It tells me that mmap failed: Cannot allocate memory. Is there a limited max hugepages or memory size for dpdk to mmap EAL memory?
Some information as follows: 1. Environment: Host OS: Suse11 Sp3 x86_64 NIC: intel 82599 DPDK: 1.6.0r2 2. Hugepage Configuration in Kernel command line: hugepagesz=2M default_hugepagesz=2M hugepages=90000 3. l2fwd command line: ./build/l2fwd -c 0x3 -n 3 --socket-mem 2048 -- -q 1 -p 3 4. cat /proc/meminfo: HugePages_Total: 90000 HugePages_Free: 90000 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB 5.
