Hi Jason,
That's patch 3 of the Hyper-V guest IOMMU driver series here:
https://lore.kernel.org/all/[email protected]/T/#m248fd782be21c7fdb79c97b1764658e6c3c5f623
That's awaiting an ack from you and Joerg to be picked up for the next merge
window or additional feedback
for the past couple of weeks.
Thanks,
Easwar (he/him)
