Hi All Currently, the only statistics we get for a VDPA instance comes from the virtio_net device instance. Since VDPA involves hardware acceleration, there can be quite a lot of information that can be fetched from the underlying device. Currently there is no generic method to fetch this information. One way of doing this can be to create a the host, a net device for each VDPA instance, and use it to get this information or do some configuration. Ethtool can be used in such a case I would like to hear what you think about this or maybe you have some other ideas to address this topic. Thanks, Eli
Something I'm not sure I understand is how are vdpa instances created on mellanox cards? There's a devlink command for that, is that right? Can that be extended for stats? -- MST _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
