From: Wei Xu <wexu@redhat.com>
This is a prototype for virtio-net 1.1 support in userspace backend,
only minimum part are included in this RFC(roughly synced to v8 as
Jason and Tiwei's RFC).
Test has been done together with Tiwei's RFC guest virtio-net driver
patch, ping and a quick iperf test successfully.
Issues:
1. Rx performance of Iperf is much slower than TX.
TX: 13-15Gb
RX: 100-300Mb
Missing:
- device and driver
- indirect descriptor
- migration
- vIOMMU support
- other revisions since v8
- see FIXME
Wei Xu (8):
virtio: feature bit, data structure for packed ring
virtio: memory cache for packed ring
virtio: add empty check for packed ring
virtio: add detach element for packed ring(1.1)
virtio: notification tweak for packed ring
virtio: flush/push support for packed ring
virtio: get avail bytes check for packed ring
virtio: queue pop support for packed ring

A new memory cache is introduced to for packed ring,
the code looks pretty duplicated with split(1.0) ring,
any refactor idea?

mostly as same as 1.0, copy it separately for
prototype, need a refactoring.

cloned from split ring pop, a global static length array
and the inside-element length array are introduced to
easy prototype, this consumes more memory and it is valuable
to move to dynamic allocation as the out/in sg does.

Hi,

This needs to be investigated. What's the pps of TX/RX then? (Maybe you
can try Jen's dpdk code too).

I think we can reuse exist memory region caches? Especially consider
device/driver area could be treated as a renaming of avail/used area.
E.g desc for desc_packed, avail for driver area and used for device area.

Do you mean the number of chained descriptors?

What's the use of this bit? If you refer to my v1 vhost code, I used to
have this, but it won't work for OOO completion e.g when zerocopy is
disabled. I've dropped it now.
This is tricky and can only work when device complete descriptors in order.

What we need here is to make sure flag is read before all other fields,

I think you'd better have a switch inside virtio_queue_empty_rcu() like
virtio_queue_empty() here.

It's odd and hard to review if you put detach patch first. I think this
patch needs to be reordered after the implementation of pop/map.
Thanks

Yes, I haven't tune any tso/gso on tap so the pps should match the bandwidth,
will try some more debugging and tried Jen's code if I can not resolve it.

To ease the reviewer, I suggest to reorder this patch to patch 4.

This seems wrong, we could not assume buffer id is last_avail_idx.

This seems unnecessary, spec said:
"
In a used descriptor, Element Address is unused. Element Length
specifies the length of the buffer that has
been initialized (written to) by the device.
Element length is reserved for used descriptors without the
VIRTQ_DESC_F_WRITE flag, and is ignored
by drivers.

Shouldn't elem->len be determined by virtqueue_fill()?

Same here, num could not be a power of 2.

Only few minors difference with split version, can we manage to unify them?

This should be determined by the caller, especially for the WRITE

We should make sure flags is written after other fileds. So need a wmb()
between the two writes.

Have you tested the case when elem->count is greater than one? According
to the spec device only need to write a single used descriptor for the
whole list.
