[dpdk-users] CMake configuration

[dpdk-users] CMake configuration

[Rob Zimmerman]

Has anybody tried setting up a CMake environment for their DPDK-based
application? The only example I saw was on Github and is from 2 years ago,
thus irrelevant. Given the complexity of the existing DPDK build scripts I
figured it was worth reaching out to the list before starting to whip up my
own from scratch.

Cheers,
Rob

[dpdk-users] Tx/Rx using single ethernet port.

[Dharmesh Mehta]

Hello,
I am new to DPDK world, and looking for any working example  to do tx/rx on single ethernet port. Also please include what arguments are required in order to run.
Is it possible to run multiple instance of same application? I wrote one app, which sens data (verified on wireshark),  but when i try to run second instance of same app, my first instance of same app  stop sending data. I am passing different name using --file-prefix to the both instances app. Any help is really appreciated.
ThxD.

Re: [dpdk-users] Tx/Rx using single ethernet port.

[Dharmesh Mehta]

Hello Keith,
Thank you so much, As per your suggestion- now i can run multiple instance of same application. Issue was, I was not doing black list of unused ports.
Once again, thanks for your help.
Regards,D.

Running two instance or more you have to split up the resources like lcores, ports, memory and the file-prefix. Make sure you have enough memory setup to run two instances. If your app needs 32 huge pages then make sure you have 64 huge pages allocated. Set the —file-prefix different for each instance. Make sure you use the -m <memSize> or —socket-mem options to limit the amount of memory each instance consumes. Make sure you blacklist/whitelist the ports correctly to give a port(s) to each instance. Then make sure you use different cores for each instance.

In Pktgen I have two scripts I use to run two instances. Here are the scripts called pktgen-master.sh and pktgen-slave.sh

pktgen-master.sh
————————
dpdk_opts="-l 8-16 -n 4 --proc-type auto --log-level 7 --socket-mem 512,512 --file-prefix pg1"
pktgen_opts="-T -P"
port_map="-m [9:10].0 -m [11:12].1 -m [13:14].2 -m [15:16].3"
bl_common="-b 05:00.0 -b 05:00.1 -b 82:00.0 -b 83:00.0"
black_list="${bl_common} -b 81:00.0 -b 81:00.1 -b 81:00.2 -b 81:00.3"
load_file="-f themes/black-yellow.theme"

echo ${cmd} ${dpdk_opts} ${black_list} -- ${pktgen_opts} ${port_map} ${load_file}
sudo ${cmd} ${dpdk_opts} ${black_list} -- ${pktgen_opts} ${port_map} ${load_file}


pktgen-slave.sh
———————
dpdk_opts="-l 18-26 -n 4 --proc-type auto --log-level 7 --socket-mem 512,512 --file-prefix pg2"
pktgen_opts="-T -P"
port_map="-m [19:20].0 -m [21:22].1 -m [23:24].2 -m [25:26].3"
bl_common="-b 05:00.0 -b 05:00.1 -b 82:00.0 -b 83:00.0"
black_list="${bl_common} -b 04:00.0 -b 04:00.1 -b 04:00.2 -b 04:00.3"
load_file="-f themes/black-yellow.theme"

echo ${cmd} ${dpdk_opts} ${black_list} -- ${pktgen_opts} ${port_map} ${load_file}
sudo ${cmd} ${dpdk_opts} ${black_list} -- ${pktgen_opts} ${port_map} ${load_file}
