Hi,
New to the dpdk and just downloaded 1.7. I attempting to execute the test
application (17) in Dom0 through the setup script.
It hangs during or just after setting up memory. I know I'm doing something
wrong, I just can't quickly figure out it is.. need some help !!
I have UIO and KNI modules loaded and 64 pages NUMA shared memory. (I also
tried 64 pages non-numa with the same result.)
See:
Option: 17
Enter hex bitmask of cores to execute test app on
Example: to execute app on cores 0 to 7, enter 0xff
bitmask: 0x01
Launching app
EAL: Detected lcore 0 as core 1 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 2 on socket 0

EAL: Detected lcore 5 as core 3 on socket 0
EAL: Detected lcore 6 as core 4 on socket 0
EAL: Detected lcore 7 as core 4 on socket 0
EAL: Support maximum 64 logical core(s) by configuration.
EAL: Detected 8 lcore(s)
EAL: unsupported IOMMU type!
EAL: VFIO support could not be initialized
EAL: Setting up memory...
Using debian jessie 3.14-1-amd64 #1 SMP Debian 3.14.4-1 (2014-05-13) x86_64
GNU/Linux with XEN 4.3.0
Any suggestions ?

Hi, New to the dpdk and just downloaded 1.7. I attempting to execute the test application (17) in Dom0 through the setup script. It hangs during or just after setting up memory. I know I'm doing something wrong, I just can't quickly figure out it is.. need some help !! I have UIO and KNI modules loaded and 64 pages NUMA shared memory. (I also tried 64 pages non-numa with the same result.)
