Subject: [Qemu-devel] [PATCH v2 0/2] Add virtio-fs (experimental)
Date: Fri, 23 Aug 2019 18:56:55 +0100 [thread overview]
Message-ID: <20190823175657.12085-1-dgilbert@redhat.com> (raw)
From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
Hi,
This pair of patches adds the core of the virtio-fs support to qemu;
it's marked experimental since the kernel patch and spec changes aren't
in yet; but they're bubbling along.
While the spec change is still in progress; the ID number is already
reserved.
A future set of patches will add the optional DAX mapping support.
The actual qemu change is pretty minimal, since it's really only
a virtio device with some queues.

virtio spec changes: https://lists.oasis-open.org/archives/virtio-dev/201908/msg00104.html
v2:
Renamed num_queues to num_request_queues
Add a not-reached assert to vuf_handle_output
Kill the one bit of notification queue off
Use the same trick as vhost-user-scsi to calculate the number
of vectors for the PCI device
