Sorry I have no plan yet.
Could you send me your logs on your AMD system?
Thanks

Hi Joerg, ZhenHua,
This issue happens on AMD iommu too, do you have any plans or
thoughts on that?
Thanks

I am working following your directions:
1. If the VT-d driver finds the IOMMU enabled, it reuses its root entry
table, and do NOT disable-enable iommu. Other data will be copied.
2. When a device driver issues the first dma_map command for a
device, we assign a new and empty page-table, thus removing all
mappings from the old kernel for the device.
Please let me know if I get something wrong.
Yes, this sounds right. Happily waiting for patches :)
