I'm working on v2 and getting ready for another review but not sure how
to address this feedback. For now, I can drop this patch from the series

Don't.  The solution is to use UEFI, which runs in 64-bit mode and can
do DMA to shared pages.


Thanks.

I will explore UEFI BIOS path. Just for confirmation you mean the OVMF project [1] right ?
