Windows 10/11 x64 signed NetUIO and virt2phys packages - listed Microsoft contact is no longer valid

Dear DPDK Windows maintainers and users,

We are evaluating DPDK for production deployment on Windows 10 x64 and Windows 11 x64.

Our hardware includes Intel XL710 adapters, NVIDIA/Mellanox ConnectX adapters using the mlx5 PMD, and other PCIe network adapters.

We need precompiled, production-ready, Microsoft-signed or WHQL-certified x64 installation packages for:

1. NetUIO
2. virt2phys

The NetUIO README currently states that a WHQL-signed NetUIO driver can be requested from dpdkwin@microsoft.com:

https://git.dpdk.org/dpdk-kmods/tree/windows/netuio/README.rst

However, that address is no longer valid. Microsoft rejected the message with:

550 5.4.1 Recipient address rejected: Access denied

Could you please confirm:

1. Whether signed NetUIO and virt2phys packages currently exist for Windows 10/11 x64.
2. Whether they are publicly downloadable or available through a vendor or commercial support channel.
3. The current contact responsible for obtaining these packages.
4. Whether NetUIO supports Intel XL710/E810 and other PCI device IDs in a signed package.
5. Whether virt2phys is still required for mlx5 with WinOF-2, or whether IOVA-as-VA is officially supported in production.
6. Whether the packages support Secure Boot and HVCI / Windows Memory Integrity.
7. Whether redistribution with a commercial application is permitted.
8. Whether the obsolete dpdkwin@microsoft.com address can be removed or replaced in the dpdk-kmods documentation.

Relevant source and documentation:

virt2phys:

Thank you for any current information or contact details you can provide.

Best regards,

Hello,

Thank you for the catch and the good questions.
We need answers from Microsoft, Intel and NVIDIA.

Please see below

I think there is a signing procedure here:
https://learn.microsoft.com/en-us/windows-hardware/drivers/install/whql-release-signature

Unfortunately, after 7 years since first introduction of Windows support,
the roadmap still mentions "inbox kernel-mode driver" in "Future (unscheduled)".

Anyone from Microsoft can answer please?

Anyone from Microsoft can answer please?

We really need to state who is responsible in Microsoft.


> 4. Whether NetUIO supports Intel XL710/E810 and other PCI device IDs in a signed package.

The question refers to i40e and ice drivers support on Windows.
Someone from Intel to answer please?


> 5. Whether virt2phys is still required for mlx5 with WinOF-2,

It is said "required by hardware PMDs" but I am not sure it is true with IOVA-as-VA.
We should explain this clearly in
https://doc.dpdk.org/guides/windows_gsg/run_apps.html#install-drivers

> or whether IOVA-as-VA is officially supported in production.

It is not said it is officially supported, but I suppose it should work.
Someone from NVIDIA to confirm please?


> 6. Whether the packages support Secure Boot and HVCI / Windows Memory Integrity.
> 7. Whether redistribution with a commercial application is permitted.
> 8. Whether the obsolete dpdkwin@microsoft.com address can be removed or replaced in the dpdk-kmods documentation.

We need Microsoft support for these questions.
