Re: [vpp-dev] VPP Iperf3 test

2022-03-22 Thread Florin Coras

Hi Shankar, 

What vpp version is this? For optimizations, could you take a look at a recent 
version of [1]?

Having said that, let’s try debugging this in small steps. First, I’d recommend 
not exporting LD_PRELOAD instead doing something like:

sudo sh -c “LD_PRELOAD= VCL_CONFIG= iperf3 -4 -s”
sudo sh -c “LD_PRELOAD= VCL_CONFIG= iperf3 -c 10.21.120.181”

I’m assuming here that you’re running 2 vpps on two different hosts. Also, no 
need for -b on client side, tcp tests scale up by default. 

With respect to your startup.conf, no need to configure default buffer size, 
buffers can be kept at 16384. With recent vpp versions  evt_qs_memfd_seg is no 
longer needed under session stanza. 

If results don’t change. “show session verbose 2” on both client and server 
side vpp. 

Regards,
Florin

[vpp-dev] VPP Iperf3 Test #vpp-dev

2022-03-22 Thread Shankar Raju

Hi Guys,

I’m trying to test VPP configuration with iperf3 and I running into the 
following issue.

· Iperf3 client is able to make a connection with the server, but the client 
receives data for the first 0-1 second and then it does not receive any traffic 
from the server. The bitrate is zero after that.

Here’s my startup.conf and vcl.conf

STARTUP.CONF

unix {

nodaemon

log /var/log/vpp/vpp.log

full-coredump

cli-listen /run/vpp/cli.sock

gid vpp

## run vpp in the interactive mode

# interactive

## do not use colors in terminal output

# nocolor

## do not display banner

# nobanner

}

api-segment {

gid vpp

}

socksvr {

default

}

dpdk {

uio-driver vfio-pci

dev :00:06.0 {

name eth1

}

}

buffers {

buffers-per-numa 65536

default data-size 2048

}

cpu {

main-core 0

workers 1

}

session {

evt_qs_memfd_seg

}

VCL.CONF

vcl {

rx-fifo-size 80

tx-fifo-size 80

app-scope-local

app-scope-global

api-socket-name /var/run/vpp/api.sock

}

Steps I followed:

· Set IP address through vpcctl

Iperf3 server command:

· export LD_PRELOAD=$LDP_PATH && export VCL_CONFIG=$VCL_CFG

· iperf3 -4 -s -A 1 -V

iperf3 client command:

· export LD_PRELOAD=$LDP_PATH && export VCL_CONFIG=$VCL_CFG

· iperf3 -c 10.21.120.181 -u -A 1 -V -b 0

Funny you should mention 30573 -- yesterday I noticed this was in limbo 
& broken.  I am in the process of fixing the bugs in this documentation 
so that it can be merged.


While I'm at it, I will be be updating the CI verify job to upload the 
doc verify results to an AWS S3 bucket with a 7 day retention policy to 
enhance the documentation review process.

Hello,

I noticed that the latest version of the memif library is lacking
documentation and the things that are in there seem a bit outdated.

I am mostly interested in the multi threaded support in memif,
which in older versions seemed to be offered by the library but now
they’ve been removed.

Do you have some documentation and code examples on how memif
should be handled by multiple threads concurrently?

Best regards,
Catalin

[vpp-dev] Cross Compile VPP from x86 ubuntu to aarch64 ubuntu , but failed #dpdk

2022-03-22 Thread 1800012701

hello everyone,
I am trying to running VPP+DPDK on my embedded development board whose 
architecture is aarch64 with system ubuntu16.4.
Finally the vpp runs, but it turns out that it doesn't include DPDK plugin so I 
can't continue my development.

My first question is, IS THERE ANY DOCUMENT FOR CROSS-COMPILATION?

and here are my steps of cross compiling:
according to https://blog.csdn.net/guoqixin2008/article/details/122415704

1. git clone vpp codes and checkout stable/2101 branch
2. make install-dep ; make install-ext-dep
(in step 2, log showed that missing Libbpf dependency)

3.download aarch64-linux-gnu-gcc ,download openssl and libuuid , config them 
with aarch64-linux-gnu-gcc (compiler and lib prefix, therefore the .so and .a 
will  be located at lib of aarch64-linux-gnu-gcc) and then make openssl and 
libuuid.
4.set vpp/src/Cmakelists.txt by adding my config of cross compilation.

5. make build
(in step 5, only openssl and libuuid is loaded, other libs like RDMA ipsec 
which were installed at step2 not. *so I wonder that whether step 2 actually 
doesn't work for cross compilation since the runtime lib should be compiled for 
aarch* *64， that's my second question* )

6. scp build-root/install-vpp_debug-native/vpp to embedded development board, 
export LD_LIBRARY_PATH and run ./vpp ./vppctl ……

Finally, though the fido vpp logo shows in the shell when running vppctl , it 
doesn't have DPDK plugin.

*what can I do？*

Sincerely Regards.
