[vpp-dev] vpp plugin path find error #plugin

2022-11-21 Thread aihua1980

dear all:
in  vpp_find_plugin_path () function,

there is some change from version 2005,
in version 2005 is this fragment
s = format (0, "%s/lib/" CLIB_TARGET_TRIPLET "/vpp_plugins:"
"%s/lib/vpp_plugins", path, path);
in version 2202 is this fragment
s = format (0, "%s/" CLIB_LIB_DIR "/vpp_plugins", path, path);
what is  the second path for?

in version  2202，split_plugin_path  Looks like it didn't work.

the same as  function vat_find_plugin_path()

Re: [vpp-dev] How to make VPP work with Mellanox ConnectX-6 NICs?

2022-11-21 Thread Chinmaya Aggarwal

Hi Elias,

We are trying to configure Mellanox ConnectX-5 interface with VPP v22.02 using 
RDMA driver. We are able to create rdma interface, but when we try to configure 
those rdma interfaces inside lacp bonding we don't see it working. The "show 
bond" command only shows one active member rather than two.
Below are the configuration we tried:-
vpp# create int rdma host-if eth1
vpp# create int rdma host-if eth2
vpp# set interface promiscuous on eth1/0
vpp# set interface promiscuous on eth2/1
vpp# set int state eth1/0 up
vpp# set int state eth2/1 up
vpp# create bond mode lacp id 0
vpp# bond add BondEthernet0 eth1/0
vpp# bond add BondEthernet0 eth2/1
vpp# set int state BondEthernet0 up
vpp# set int state eth2/1 up
vpp# set int state eth1/0 up

Can you please tell if we are missing something here?

This issue has been raised on VPP mailing as well:-
https://lists.fd.io/g/vpp-dev/topic/94956154#22183

Thanks and Regards,
Chinmaya Agarwal

Re: [vpp-dev] "tx frame not ready " error in host-vpp1out tx

2022-11-21 Thread Guangming

Hi Mohsin 
I have find the root cause of this issue. VPP send a huge malform  packet 
to linux kernel,   
  the memcpy  in VNET_DEVICE_CLASS_TX_FN (af_packet_device_class)  
overwrite the tx_ring

Hi,Mohsin
 
I used  linux veth pari interface as af-packet interfeace in vpp. 
When  the vpp run for some time,  there are many "tx frame not ready " error  
in  host-vpp1out-tx.
If there is error, we can not ping from linux side to vpp side. Must need 
restart vpp to restore. 
From old mail. you say "tx frame not ready" means VPP didn't find empty queue 
at linux side.  But in my
envirment ,the trafiic is not big .Could give me some clues?

Subject: Memif performance

Hi Team,
I am trying to transfer packets between two applications(one written in C++ and 
the other in go-lang). I am using the latest build for both C-memif and 
Go-memif. The performance I am getting is lower than the IP-based socket.

Configuration applied in memif.

num_s2m_rings/NumQueues - 1
num_m2s_rings/NumTxQueues - 1
buffer_size/BufferSize  - 2048
log2_ring_size/Log2RingSize   - 10
mode  - Ethernet(0)

There is no queuing of the packet happening but still, I am getting throughput 
well below the actual IP-based socket communication.

Could anyone help please in this regard ?

Thanks,
Praveen.
