Hi Shreyansh,
Thanks for the reply.
By using the set-up script in DPDK:
the hugepage memory looks to be allocated properly:
cat /proc/meminfo
HugePages_Total: 240
HugePages_Free: 240
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 2048 kB
and then i run the commands below in sequence:
$ sudo modprobe uio
$ sudo insmod ./build/kmod/igb_uio.ko
$ sudo ./usertools/dpdk-devbind.py -b igb_uio xxx:xx.0 xxx:xx.1 (
xxx.xx.0, xxx.xx.1 <-- 10G port pci address )
$ sudo ./build/app/testpmd -l 1,2,3 -n 2 -- -i

Questions below:
1. It looks like the application can enter the interactive mode. however, I
have no idea why *EAL: No free hugepages reported in hugepages-1048576kB *keeps
popping out.
2. Is there any reason why the ports went down why I run the commands? The
Link was up before running it.
3. The hugepage will be gone after running this application.
HugePages_Total: 240
HugePages_Free: 0
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 2048 kB
It became this. However, how can i free it again ? I tried to umount and
mount again but it did not work.
Please advice if any.
Paul
