Subject: VDPA Debug/Statistics
Date: Tue, 11 Aug 2020 11:26:20 +0000	[thread overview]
Message-ID: <BN8PR12MB342559414BE03DFC992AD03DAB450@BN8PR12MB3425.namprd12.prod.outlook.com> (raw)

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
