[dpdk-dev] EAL reports "ot enough memory available on socket 0!"

[Huertas García, Víctor]

Hi all,


This is my first post in this mailing list. I am glad to become a member of this community.


I am a newbie using DPDK and I have tried to compile and execute an example app called "l3fwd-acl".


The DPDK command is DPDK_Test -c 0xf0 -n 2 --socket-mem 64

but the application tells me the following:


EAL: Detected 8 lcore(s)
EAL: Probing VFIO support...
EAL: VFIO support initialized
EAL: Cannot obtain physical addresses: Success. Only vfio will function.
EAL: Not enough memory available on socket 0! Requested: 64MB, available: 0MB
EAL: FATAL: Cannot init memory

EAL: Cannot init memory

EAL: Error - exiting with code: 1
  Cause: Invalid EAL parameters



I don't know what else I can do to make this app run as I have reserved hugepages as the user guide tells as well as mounted the /mnt/huge folder.


cat /proc/meminfo | grep Huge
AnonHugePages:    520192 kB
HugePages_Total:      64
HugePages_Free:       64
HugePages_Rsvd:        0
HugePages_Surp:        0
Hugepagesize:       2048 kB


My machine is has this topology (only one Numa node is detected):


udo usertools/cpu_layout.py
[sudo] password for root:
======================================================================
Core and Socket Information (as reported by '/sys/devices/system/cpu')
======================================================================

cores =  [0, 1, 2, 3]
sockets =  [0, 1]

       Socket 0    Socket 1
       --------    --------
Core 0 [0]         [4]
Core 1 [1]         [5]
Core 2 [2]         [6]
Core 3 [3]         [7]



I have compiled the application using Eclipse IDE (g++) under an OpenSuse 42.3 Leap. Everything seemed to compile well and vfio-pci driver could be loaded on two NICs.

So everything seems to be OK but I am totally stuck on this EAL initialization problem.


I would appreciate it if some expert could shed a light on my problem.


Thanks a lot!!
