[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 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. It definitely won't work as-is on s390x, and

[PATCH v5 0/3] virtio: Use the DMA API when appropriate
This fixes virtio on Xen guests as well as on any other platform that uses virtio_pci on which physical addresses don't match bus addresses. This can be tested with: virtme-run --xen xen --kimg arch/x86/boot/bzImage --console using virtme from here: https://git.kernel.org/cgit/utils/kernel/virtme/virtme.git Without these patches, the guest hangs forever.

[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 v3 0/3] virtio DMA API core stuff
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. Changes from v2: - Fix really embarrassing bug. This version actually works. Changes from v1: - Fix an endian conversion error causing a BUG to hit. - Fix a DMA ordering issue

[PATCH net-next v2 0/5] virtio: support packed ring
Hello everyone, This patch set implements packed ring support in virtio driver. Some functional tests have been done with Jason's packed ring implementation in vhost: https://lkml.org/lkml/2018/7/3/33 Both of ping and netperf worked as expected. v1 -> v2: - Use READ_ONCE() to read event off_wrap and flags together (Jason); - Add comments related to ccw (Jason); RFC (v6) -> v1: -
