DPDK on Xen Dom-U hangs during hugepage setup

DPDK on Xen Dom-U hangs during hugepage setup

[Kiran KN]

Hello,

I am trying to bring up DPDK on Xen Dom-U.

Have followed all the steps in DPDK programmers guide in section 14.3.

However, when I try to run testpmd or any other example application, it is getting stuck during hugepage setup.

It hangs after the print "EAL: Setting up memory..."

Has anyone faced similar issue before?

Thanks,
 Kiran

Hello,

Xen does not support hugepages, so you have to use a kernel module 
called rte_dom0_mm.
The instructions are in the getting started guide in the seccion 2.3.3.
If you manage to execute any example please tell me, because I am stuck 
during the execution of the examples after configuring the environment.

Hello Murillo,

Yes, am using rte_dom0_mm as explained in DPDK programmers guide section 14.3.3 step (4).

The examples work when using --no-huge option. 

Are you able to go past the hugepage setup? If so can you tell what are the steps you followed in addition to the ones explained in section 14.3.

Thanks,
 Kiran

Hello Kiran,

I was able to execute the helloworld example by running the next steps:

Change in Dpdk/config/common_linuxapp
CONFIG_RTE_LIBRTE_XEN_DOM0=n
to:
CONFIG_RTE_LIBRTE_XEN_DOM0=y
Change indpdk/config/defconfig_x86_64-native-linuxapp-gcc
CONFIG_RTE_MACHINE="native"
To
CONFIG_RTE_MACHINE="default"
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
cd example/helloworld
make
./build/helloworld -c 0x3 -n 2 --xen-dom0 –no-huge

[Liu, Jijiang]

The "-no-huge" option is not needed in this case.
