Do you have a git tree somewhere to look at the whole tree?
Yes, here is my github link for these

This is still broken. You need to make sure the actual DMA allocations

Hi Christoph:
swiotlb_tbl_map_single() still returns PA below vTOM/share_gpa_
boundary. These PAs has backing pages and belong to system memo
This is still broken. You need to make sure the actual DMA allocations

In Isolation VM with AMD SEV, bounce buffer needs to be accessed via
extra address space which is above shared_gpa_boundary
(E.G 39 bit address line) reported by Hyper-V CPUID ISOLATION_CONFIG.
The access physical address will be original physical address +
shared_gpa_boundary. T
