[dpdk-dev] FW: MENNIC1.2 host-sim crashed for me

[Srinivas Reddi]

Hi Hiroshi,
Thanks for ur reply .. I have moved forward little bit.

MEMNIC-1.2

1. I started qemu and then started host-sim application

Qemu command :
qemu-system-x86_64 -enable-kvm -cpu host   -boot c -hda /home/vm-images/vm1-clone.img -m 8192M -smp 3 --enable-kvm -name vm1 -vnc :1 -pidfile /tmp/vm1.pid -drive file=fat:rw:/tmp/share  -device ivshmem,size=16,shm=ivshm
vvfat fat:rw:/tmp/share chs 1024,16,63

2.Host-sim app command :
3.[root@localhost host-sim]# ./memnic-host-sim   /dev/shm/ivshm
4.On the guest compiled  memnic-1.2 .
5.Inserted memnic.ko
6.Found and interface ens4  after insmod memnic.ko

[root@localhost test-pmd]#

How can I bind 00:04.0 Ram controller to dpdk application (test-pmd ) .
How DPDK test-pmd application finds the memnic device.

9.Am I missing any steps in the guest configurations or host configuration .
10.Is there any better manual for testing MEMNIC-1.2 or better understanding .
11.Is there any better application  to test MEMNIC   for VM-VM  or VM to host data transfer .

Thanks &  regards,
Srinivas.

I have never tried host-sim yet though.
I guess it's the cause that host-sim doesn't increase the shared memory size.
Could you try booting qemu first with -device ivshmem,size=16,shm=/ivshm then run host-sim?

thanks,
Hiroshi

you cannot use both kernel driver and PMD concurrently.
Before run testpmd, you should unload memnic.ko by rmmod command.

I don't know about testpmd so much, but I guess the correct EAL parameters are like this.

# ./testpmd -c 0x7 -n 3 -d /usr/local/lib/librte_pmd_memnic_copy.so -- ...

Please pass extra library in EAL parameter.

I think the current host-sim doesn't have any packet switching capability, we need to implement such
a functionality to test MEMNIC.

Actually, I started MEMNIC develop in DPDK vSwitch project.
You can see that in https://github.com/01org/dpdk-ovs/tree/development

Hi Hiroshi ,

Thanks for your comments ...
I found dpdk1.6  doesn't work for MEMNIC.1.2 ..
I tried with dpdk-1.7 .. It worked for me ..

you cannot use both kernel driver and PMD concurrently.
Before run testpmd, you should unload memnic.ko by rmmod command.

I don't know about testpmd so much, but I guess the correct EAL parameters are like this.

# ./testpmd -c 0x7 -n 3 -d /usr/local/lib/librte_pmd_memnic_copy.so -- ...

Please pass extra library in EAL parameter.

I think the current host-sim doesn't have any packet switching capability, we need to implement such a functionality to test MEMNIC.

Actually, I started MEMNIC develop in DPDK vSwitch project.
You can see that in https://github.com/01org/dpdk-ovs/tree/development
