Hi,
This v4 patch uses vfio-noiommu-way to access virtio-net pci interface.
Tested for arm64 thunderX platform. Patch builds for
x86/i386/arm/armv8/thunderX. Tested with testpmd application.
Refer v3 [1] cover letter for dependancy description:
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.
For patch history from v1-->v3 pl. refer v3 cover letter [1]
v3--> v4:
- Incorporated v3 review comments, Thanks to Stephen, Yuan, Bruce for comment!
- Tested for Huawei patch series titled "[PATCH v2 0/4] fix the issue that DPDK
takes over virtio device blindly".
- Patch no 11 and 13 are testonly patches used for this patch series [Anatoly/
Yuan]
Major change in series:
- Introducing vfio interface parse api in virtio pmd driver
- Added vfio device specific private header in struct virtio_hw{}
- Dummy in/oub x86-style api, just to pass build error for non-x86 arch for vfio
mode.
- VIRTIO_REG_RD/WR API(s) are now able to do rd/wr for both interfaces i.e. for
vfio and igb_uio/ioport bar. Tested for both mode for x86 and also only for
vfio for arm64 (non-x86) archs.
So to try-out complete patc-set w/o cut-n-paste pain clone this [2]
Thanks!.
