Subject: [vhost] vhost_get_vq_desc, vq->iov mapping
Date: Wed, 6 May 2015 13:01:51 +0300 [thread overview]
Message-ID: <5549E68F.7030206@freescale.com> (raw)
From what I know, qemu and vhost backends use some functions in order
to access the memory between the guest and the backend.
From what I see, vhost does this with vhost_get_vq_desc().
How much do vq->iov mappings remain valid? Does it get unmapped at some
time (you could answer me within vhost-net or vhost-scsi
as examples)?
