Hi Team,
I tried to reach out for Windows based DPDK over users@dpdk.org,admin@dpdk.org and windows developers in DPDK. But I didnot receive any reply from anyone. Can you please direct the mail to the corresponding person-in charge.

I am using Virtio-PMD for my custom design in my Linux OS and is operational both in functional and throughput level. I wanted to know whether the Virtio-PMD (drivers/net/virtio) available in Linux; Is feasible in Windows OS?
What changes to be made to support this? If not supported, could you please elaborate the reason?

In addition linux has pcimem/devmem to access PCI resources, Does Windows has similar application?

In https://core.dpdk.org/roadmap/windows/ link shows, the feature supported, but no example where specified. Could you please let me know the tests/workaround performed with this PMD.

I tried to reachout at dpdkwin@microsoft.com for the same, the mail response shows "Your message to dpdkwin@microsoft.com couldn't be delivered". Is this mail id deprecated?

Thanks and regards,
Ayshathul Thuhara

Hi Ayshathul,

Adding Andre as currently the most involved Windows DPDK maintainer.

Virtio PMD could work in QEMU-KVM on Linux host with Windows guest as PoC.
However, the patches were never completed and merged
because of a few toolchain-related issues that no one had time to resolve.
In DPDK, the latest patch is this
(check also the link in that message and the discussion):

https://inbox.dpdk.org/dev/20210815145614.3826-1-u9012063@gmail.com/

In DPDK kmods repository, you'd need to add PCI IDs to the INF file.

Hi Team,

       Thankyou for providing this input.

In addition we have a few queries while running DPDK in Windows.
(A) On what scenario or an example,  can Virt2PHY driver be used?
(B) After we bind the interface using netuio.inf file, the example application testpmd.exe shows "No probed ethernet device". But in Device manager the interface shows available and bind with QDMA. Here we are using QDMA-PMD(https://github.com/Xilinx/dma_ip_drivers/tree/master/QDMA/DPDK) driver. This driver works with Linux environment.(Please let me know if we need to create new mail for this).

Thanks and regards,
Ayshathul Thuhara
