Getting (WARNING: requested port 0 not present - ignoring) while running dpdk

Question

I have tried to run dpdk in my redhat6.3 verison.

Ports are there, but still i can't run dpdk using "0000:43:00.0 '82599EB"

what is the problem ?

Same configuration i am using to run DPDK for .&checktime(0000,46,00,':').0 and .&checktime(0000,43,00,':').0. but the above 82599EB NIC is not running why?

The same time Dpdk is able to run with .&checktime(0000,46,00,':').0 'Device 155d' [This LOGS are below]

• Andriy Berestovskyy: Looks like the logs are incomplete. Please include complete logs, including the command line arguments you are using to run the DPDK app.
• Prasanna Raja: <imagefile> -coreId 5 -socket 0 -c 20 -n 4 --proc-type=primary --socket-mem=512,0,0,0 -b 0:01:0.0 -b 0:01:0.1 -b 0:01:0.2 -b 0:01:0.3 -b 0:46:0.0 -b 0:46:0.1 -b 0:41:0.0 -b 0:41:0.1 -b 0:07:00.0 -b 0:07:00.1 -b 0:03:0.0 -b 0:03:0.1 -b 0:05:0.0 -b 0:05:0.1 -- -p 3 -n I have blocked all ports (43th port alone memory is created properly but its showing port is note present) (i used to run dpdk by this config file) –

Answer 1

imagefile -coreId 5 -socket 0 -c 20 -n 4 --proc-type=primary --socket-mem=512,0,0,0 -b 0:01:0.0 -b 0:01:0.1 -b 0:01:0.2 -b 0:01:0.3 -b 0:46:0.0 -b 0:46:0.1 -b 0:41:0.0 -b 0:41:0.1 -b 0:07:00.0 -b 0:07:00.1 -b 0:03:0.0 -b 0:03:0.1 -b 0:05:0.0 -b 0:05:0.1 -- -p 3 -n

There are few problems with the command line:

1. The -coreId, -socket is not a valid DPDK command line argument. That is probably your app custom arguments?

2. The --proc-type is used for multiprocess application, usually we don't need this option.

3. The --socket-mem=512,0,0,0 allocates 512MB on NUMA node 0 and zero on nodes 1-3. But please note, that some of your NICs are on NUMA node 1 in fact, so we need to allocate some memory there as well.

4. Instead of a bunch of -b (blacklist) options we can use just one or two -w (whitelist)

Still it does not explain why there is no .&checktime(0000,43,00,':').0 device appeared. So pease try to add --log-level=debug to see what is happening to this device.
