I think a super-short description of vDPA here (one sentence?) together with a link to complete information would be helpful. If the link's target doesn't yet exist, adding the link later is okay.

Sure will add this Not sure it's the best place since vhost-vdpa is kernel specific. Maybe kernel docs (TBD) is a better place and we can refer it this file in the future. But it doesn't harm if you said something more here and refer the kernel commit here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4c8cf31885f69e86be0b5b9e6677a26797365e1d Thanks
