Grab information on VFs for SR-IOV PFs #92
Comments
|
Since I don't have any machines with SR-IOV enabled NICs, I'm probably going to need to get #66 going in order to "test" this functionality |
|
I have access to boxes with low and high end SRIOV cards and I can provide snapshots (albeit most likely for low-end cards only) to enable others. |
That is awesome news, @fromanirh! Would be great to get contributions from you in this area! |

first draft, RFC for API: #230 |

Add support to report SRIOV devices. Much like GPU devices, support is added using a new top-level package. SRIOV devices are either Physical Functions or Virtual functions. The preferred representation for ghw is Physical Functions, whose dependent devices will be Virtual Functions; however, for the sake of practicality, the API also exposes soft references to Virtual Functions, so consumers of the API can access them directly and not navigating the parent devices. This patch also adds support in `ghwc`, to report the sriov information, and in the `snapshot` package, to make sure to capture all the files in sysfs that ghw cares about. Last but not least, lacking access to suitable non-linux systems, support is provided only on linux OS, even though the API tries hard not to be linux-specific.

Add support to report SRIOV devices. Differently from GPU devices, we model SRIOV devices as special PCI devices, extending the `pci` package instead of introducing a new top-level package.

It's possible to retrieve the number of virtual functions (VFs) on an SR-IOV physical function (PF) on Linux by querying the following pseudo-files:
/sys/class/net/$NIC_NAME/device/sriov_numvfs: The number of active VFs for the PF/sys/class/net/$NIC_NAME/device/sriov_totalvfs: The maximum number of VFs the PF can accomodateThe text was updated successfully, but these errors were encountered:
