Subject: [dpdk-dev] Does FreeBSD's nic_uio have bind/unbind interface support?
Date: Thu, 16 Jul 2015 17:42:16 +0530	[thread overview]
Message-ID: <20150716121214.GA3103@scalar.blr.asicdesigners.com> (raw)

Hi All,

It seems that on FreeBSD, nic_uio currently only binds the devices matched in
rte_pci_dev_ids.h.  On Linux, it's possible to bind any listed device with
igb_uio or vfio.

The pci device ids supported by cxgbe PMD, maintained in a table, are not part
of rte_pci_dev_ids.h.  Hence, Chelsio T5 cards don't get bound to nic_uio,
resulting in probe failure on FreeBSD.

On manually adding Chelsio pci device id to rte_pci_dev_ids.h, the Chelsio T5
card gets detected fine on FreeBSD.

So, we would like to know and understand if adding all supported Chelsio pci
device ids to rte_pci_dev_ids.h is the correct way of doing things for FreeBSD?

Any suggestions are appreciated.

Thanks,
Rahul
