Hi Michael and Christoph:
I just sent out V5 patchset. I use alloc_pages() to allocate rx/tx
ring buffer in Isolation VM and use vmap() to map rx/tx buffer first
because the vmbus_establish_gpadl() still needs to va of low end memory
to initialize gpadl buffer. After calling vmbus_establish_

Hyper-V provides two kinds of Isolation VMs. VBS(Virtualization-based
security) and AMD SEV-SNP unenlightened Isolation VMs. This patchset
is to add support for these Isolation VM support in Linux.
The memory of these vms are encrypted and host can't access guest
memory directly
