Subject: [dpdk-dev] l2fwd mmap memory failed
Date: Sun, 14 Sep 2014 17:01:11 +0800 [thread overview]
Message-ID: <54155957.9000400@huawei.com> (raw)
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. Error messages in dpdk log:
Sun Sep 14 08:37:28 2014:EAL: Detected lcore 0 as core 0 on socket 0
Sun Sep 14 08:37:28 2014:EAL: Detected lcore 1 as core 1 on socket 0

Sun Sep 14 08:38:44 2014:EAL: Error - exiting with code: 1

Anyone know the issue and the corresponding fix? Thanks.

Jerry
