indeed, this seems to be the case
So, in that mail thread we have the following statement:
"However, if that's not the case in any of the drivers, it
would lead to memory corruptions." with respect to get_sgtable
and pfn != mfn.
So, do you guys think I'll have to patch the offending driver?
Any other solution/workaround here?
Thank you,
Oleksandr

Hello,
I guess Oleksandr stepped into the issue described here
https://lists.xenproject.org/archives/html/xen-devel/2017-01/msg03454.html
.
He uses an old version of the patch but effectively calls
__generic_dma_ops(dev)->get_sgtable() with foreign pages so faced
troubles.
Sincerely,
Andrii Anisov
