Re: [Xen-devel] arm64: dma_to_phys/phys_to_dma need to be properly implemented

[Andrii Anisov <andrii_anisov@xxxxxxxx>]

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
