[dpdk-dev] query related to DPDK QOS-SCHED sample application

[Mahesh Ishwar Mathad]

Hi Team,

System Configuration:
NIC: Intel Corporation 82576 (IGB)
NUMA node:1
Kernel version :4.5.0
DPDK version: 16.07.2

I am trying to execute DPDK QOS-SCHED application:

  ./build/qos_sched -c 0x0e -n 1  -- --pfc "0,1,3,2" --cfg ./profile.cfg
EAL: Detected 4 lcore(s)
PMD: bnxt_rte_pmd_init() called for (null)
EAL: PCI device 0000:01:00.0 on NUMA socket -1
EAL:   probe driver: 8086:10c9 rte_igb_pmd
EAL: PCI device 0000:01:00.1 on NUMA socket -1
EAL:   probe driver: 8086:10c9 rte_igb_pmd
EAL: Error - exiting with code: 1
   Cause: No Ethernet port - bye

For qos_sched sample application require more than one NUMA node?

Appreciate your help. Thanks a lot.

Thanks!

I think the original code didn't have these functions and used the
flow_item[x].size value directly, which worked fine until I added support
for the RAW item and the RSS action. Both had to be handled through special
functions which I messed up.

Unfortunately I didn't catch it in testpmd because it doesn't do anything
with the copied data unlike the fail-safe PMD.

For this instance the application log is giving you a good instruction of where the problem might be, right? Please run the usertools/dpdk-devbind.py script to make sure that all the NIC ports you need are handled by DPDK. Please make sure you have the root privileges to run this app, huge pages are required.

No. Please take a look at the user guide on how to run this sample app: http://www.dpdk.org/doc/guides/sample_app_ug/qos_scheduler.html

Hi Team,

Thanks for the response,

$ ./build/qos_sched -c 0xe -n 4 -- --pfc "0,1,3,2" --cfg "profile.cfg"EAL: 
Detected 4 lcore(s)
PMD: bnxt_rte_pmd_init() called for (null)
EAL: PCI device 0000:01:00.0 on NUMA socket -1
EAL:   probe driver: 8086:10c9 rte_igb_pmd
EAL: PCI device 0000:01:00.1 on NUMA socket -1
EAL:   probe driver: 8086:10c9 rte_igb_pmd
EAL: Error - exiting with code: 1
  Cause: Cannot init mbuf pool for socket 0

I getting error something like this: Cannot init mbuf pool for socket 0.

$ grep -i Huge /proc/meminfo 
AnonHugePages:    350208 kB
HugePages_Total:     476
HugePages_Free:      476
HugePages_Rsvd:        0
HugePages_Surp:        0
Hugepagesize:       2048 kB

Is 476 hugepages are sufficient to execute qos_sched application?

Could you help me in running this app as per my system configuration.
