This all makes it sound as if this was generally the case, but it's so only on the AMD side. On VT-d / VT-x page table sharing continues to work. But it may be just me that I'd prefer this to not be implied from the mention of p2m-pt in the title, so I'll leave it to George as the maintainer to decide whether a further change to the description is needed. And then I would of course have wished that a cleanup patch like this one dealt with both sides, i.e. removed pt sharing remains from xen/drivers/passthrough/amd/ at the same time (i.e. if not in one patch, then at least in the same series). But this may again be just me ... Jan _______________________________________________ Xen-devel mailing list [email protected] https://lists.xenproject.org/mailman/listinfo/xen-devel
