[PATCH 0/1] target/i386/mshv: fix read and write memory across the page boundary

Posted by Doru Blânzeanu 1 day, 21 hours ago

This fixes the guest memory reading and writing spanning multiple pages for mshv Port I/O.

Currently, the read_memory and write_memory functions only translate GVA-to-GPA once per buffer.
In case the buffer is bigger than a page, the translation is only valid for the first page.
