QAT integration with dpdk

[PRadh1]

Hi,

I am trying to compile the dpdk v1.8.0 with qat "qatmux.l.2.3.0-34.tar" together to run on a CentOS 2.6.32-504.el6.x86_64 platform. The chip set I am using is Rangeley single socket quad core processor with 89xx.

Question-1: Are these two combinations of software compatible?

Question-2: I am running into a kernel panic and any help would be greatly appreciated. I followed the following steps to bring up the dpdk application..

Step-1: put together the qat configu file "/etc/c2xxx_qa_dev0.conf"

Step-2: service qat_service restart

Step-3: run the dpdk qat application

./dpdk_qat -c 0x8 -n 4 -- -q 4 -p 0x3 --config '(0,0,3),(1,0,3)'

My qat config files is attached...

Thanks in advance.

Hello Prabahar.

Welcome to Intel® Embedded Community.

You can check the system requirements at the following link:

http://dpdk.org/doc/guides/linux_gsg/sys_reqs.html http://dpdk.org/doc/guides/linux_gsg/sys_reqs.html

If you are going to use a kernel version lower than 2.6.32 you would need to apply the patch of 8.9 available at:

http://dpdk.org/doc/guides/rel_notes/faq.html# does-my-kernel-require-patching-to-run-the-dpdk http://dpdk.org/doc/guides/rel_notes/faq.html# does-my-kernel-require-patching-to-run-the-dpdk

Please note that this should be a 64bits OS.

Please add the logs of kernel panic for review.

Thanks

Best Regards.

Gabriel,

thank you for the information you have provided. I did get the QAT working for a single core access. More investigation to be done for multicore.
