[PATCH 0/3] virtio_ring: Clean up code for virtio ring and pci
This patch series performs a clean up of the code in virtio_ring and
virtio_pci, modifying it to conform with the Linux kernel coding style
guidance [1]. The modifications ensure the code easy to read and
understand. This small series does few short cleanups in the code.
Patch-1 Remove unnecessary num zero check, which performs in power_of_2.
Patch-2 Avoid using inline for small functions.

[PATCH v2 3/3] virtio_ring: Use const to annotate read-only pointer params
Add const to make the read-only pointer parameters clear, similar to
many existing functions.
Use `container_of_const` to implement `to_vvq`, which ensures the
const-ness of read-only parameters and avoids accidental modification
of their members.

[PATCH v6 0/9] virtio DMA API, yet again
This switches virtio to use the DMA API on Xen and if requested by
module option.
This fixes virtio on Xen, and it should break anything because it's
off by default on everything except Xen PV on x86.
To the Xen people: is this okay? If it doesn't work on other Xen
variants (PVH? HVM?), can you submit follow-up patches to fix it?
To everyone else: we've waffled on this for way too

[PATCH RFC 0/2] Packed ring for virtio
Hello everyone,
This RFC implements a subset of packed ring which is described at
https://github.com/oasis-tcs/virtio-docs/blob/master/virtio-v1.1-packed-wd08.pdf
The code was tested with DPDK vhost (testpmd/vhost-PMD) implemented
by Jens at http://dpdk.org/ml/archives/dev/2018-January/089417.html
Minor changes are needed for the vhost code, e.g. to kick the guest.
It's not a complete

[PATCH net-next v3 00/13] virtio: support packed ring
Hi,
This patch set implements packed ring support in virtio driver.
A performance test between pktgen (pktgen_sample03_burst_single_flow.sh)
and DPDK vhost (testpmd/rxonly/vhost-PMD) has been done, I saw
~30% performance gain in packed ring in this case.
To make this patch set work with below patch set for vhost,
some hacks are needed to set the _F_NEXT flag in indirect
descriptors (this should

[PATCH v4 0/6] virtio core DMA API conversion
This switches virtio to use the DMA API unconditionally. I'm sure
it breaks things, but it seems to work on x86 using virtio-pci, with
and without Xen, and using both the modern 1.0 variant and the
legacy variant.
This appears to work on native and Xen x86_64 using both modern and
legacy virtio-pci. It also appears to work on arm and arm64.
