Re: Inquiry About PCI Passthrough Development and Testing Patches on ARM

[shenghui qu <adam.qushenghui@xxxxxxxxx>]

Dear Stewart

Thank you for being looped into this discussion.
Following Stefano’s guidance, I’d like to seek further clarity on the current development of PCI Passthrough support for Xen/ARM.
Specifically, I have two questions:
1.Roadmap: Are there clear milestones or a timeline for completing PCI Passthrough support on ARM? For instance, is this feature targeted for inclusion in Xen 4.20 or later releases？
2.Current Status: Could you elaborate on the technical progress so far?

Looking forward to your insights.

Best regards,
Shenghui Qu

you with an overview of the latest status of PCI Passthrough on ARM.

Among the various items in progress, I would like to highlight this
series from Mykyta, which is currently under review:
