[dpdk-dev] [PATCH v5 00/11] Add virtio support for arm/arm64

[Santosh Shukla]

Hi,

Patch series uses vfio-noiommu-way to access virtio-net pci interface.
Tested for arm64 thunderX/ x86_64 platform. Patch builds for
x86/i386/arm/armv8/thunderX. Tested with testpmd application.

Patchset rebased on yuan's under review virtio-1.0 v2 patchset and using
vfio-noiommu patch. Refer my public branch [1]. 

Step to enable vfio-noiommu mode:
- modprobe vfio-pci
echo 1 > /sys/module/vfio/parameters/enable_unsafe_*
- then bind 
./tools/dpdk_nic_bind.py -b vfio-pci 0000:00:03.0

- Testpmd application to try out for:
./app/testpmd -c 0x3 -n 4 -- -i --portmask=0x0  --nb-cores=1 --port-topology=chained

On host side ping to tapX interface and observe pkt_cnt on guest side.

v4 --> v5:
- Introducing RTE_KDRV_VFIO_NOIOMMU driver mode
- Incorporated v4 review comments, Pl. refer each patchset for review change.

For older version(v4.. v1) patch history, refer [2].

Thanks.
