English is not my native language; please excuse typing errors.

I am new to DPDK with Xen, but I am able to run DPDK applications without xen using hugepages. But when I try to do it in xen-dom0 it does not work. Let me explain:

I have followed the intructions on the Getting Started Guide, so I execute the next steps:

Dpdk/config/common_linuxapp

CONFIG_RTE_LIBRTE_XEN_DOM0=y

make config T=x86_64-native-linuxapp-gcc

make install T=x86_64-native-linuxapp-gcc

sudo modprobe uio

sudo insmod x86_64-native-linuxapp-gcc/kmod/igb_uio.ko

sudo insmod x86_64-native-linuxapp-gcc/kmod/rte_dom0_mm.ko rsv_memsize=2048

echo 2048 /sys/kernel/mm/dom0-mm/memsize-mB/memsize

tools/dpdk_nic_bind.py --bind=igb_uio $(tools/dpdk_nic_bind.py --status | sed -rn 's,.* if=([^ ]*).*igb_uio *$,\1,p')

The main problem appears when I try to execute helloworld for example.

Sudo ./build/helloworld -c 0xf -n 2 –xen-dom0

Output:

EAL: Detected lcore 0 as core 0 on socket 0

EAL: Detected lcore 1 as core 0 on socket 0

EAL: Detected lcore 2 as core 1 on socket 0

…

EAL: Detected lcore 39 as core 12 on socket 0

EAL: Support maximum 64 logical core(s) by configuration.

EAL: Detected 40 lcore(s)

And it stops.

If I execute dmegs I get the following:

[ 1098.120193] helloworld[20116] trap invalid opcode ip:45adb7 sp:7fff4cf7e150 error:0 in helloworld[400000+115000]

I am sorry, I missed it during the redaction of the email. I executed it correcly. When I do "cat /sys/kernel/mm/dom0-mm/memsize-mB/memsize" it prints 2048.

Thank you for your answer and your time.

You are using Xen 4.1.5, and try to do following change In dpdk/config/defconfig_x86_64-native-linuxapp-gcc(assuming you use x86_64-native-linuxapp-gcc to compile).

Change
CONFIG_RTE_MACHINE="native"
To
CONFIG_RTE_MACHINE="default"
