Thank You for SMMU Passthrough Work – Request for Update on SMMU Nested Progress #1
Description
Dear Eric Auger,
I hope this message finds you well. I am writing to express my sincere appreciation for your outstanding work, as well as to seek an update on a related feature.
I have successfully implemented the SMMU Stage 1 passthrough functionality for guest VMs using your Linux patch (v5.6-2stage-v11_10.1) and QEMU patch (v4.2.0-2stage-rfcv6-vsva-prototype-v1). This feature is truly remarkable—it has worked flawlessly for my use case, and your implementation is exemplary in terms of both stability and design. Thank you so much for developing and sharing such valuable work with the community.
I am reaching out to kindly inquire if you have made any recent progress on the SMMU nested feature, or if there are any updates, prototypes, or documentation you would be willing to share. I understand the complexity of this work, and I would be extremely grateful for any insights or resources you can provide.
Thank you again for your incredible contributions. I look forward to your reply at your earliest convenience.
Best regards, LJKingd
