Re: [dpdk-dev] [PATCH] ixgbe: Add runtime tx/rx queue setup for X550

["Wu, Jianyue (NSB - CN/Hangzhou)" <jianyue.wu@nokia-sbell.com>]

Hi, Qi,

OK, thanks indeed for the explanation, appreciated😊
BTW, I see patch is Superseded, does that mean it is not needed, or need update?

> 1.  why only enable this for x550, is it because you only need this or you already know other ixgbe device has the limitation?
I’m using this x550 device, but not sure if other device would have such limitation yet. But I’m sure that X550 can support it, because I had checked the doc, and also tested it in the ENV.
  >2 . As the patch expose the new feature of the driver, could you provide more test information?
I tested to create new Tx Queue after rte_eth_dev_start() done and use it in my code. But haven’t tested in DPDK code yet, like testpmd.
3.  You need to update document in your patch, these include
    1) doc/guides/nics/features/ixgbe.ini
    2) if only x550 support runtime queue configure, you’d better to explain this in doc/guides/nics/ixgbe.rst.
OK, thanks, will check the documents. BTW, I see that at least there is 82599, X540, X520 is 10GE, from http://doc.dpdk.org/guides/nics/ixgbe.html, I can check their documents, but better to have some further tests, is there any ENV I can use to test it? Thanks.

Best Regards,
Dave(Jianyue)

Hi Jianyue:

 I think you can ignore those warning.

 Below are couple questions for this patch:
 1.  why only enable this for x550, is it because you only need this or you already know other ixgbe device has the limitation?
2 . As the patch expose the new feature of the driver, could you provide more test information?
3.  You need to update document in your patch, these include
    1) doc/guides/nics/features/ixgbe.ini
    2) if only x550 support runtime queue configure, you’d better to explain this in doc/guides/nics/ixgbe.rst.

Thanks
Qi

Hello, Zhang, qi,



May I ask a question?

I see this patch is delegate to you.

It seems some cases are failed in this link, but are i40e cases, can we ignore them? Because seems not related with this patch. Thanks😊
