Date: Mon, 6 Feb 2017 12:00:22 -0500 From: Boris Ostrovsky <boris.ostrovsky@...cle.com> To: JGross@...e.com Cc: roger.pau@...rix.com, xen-devel@...ts.xenproject.org, linux-kernel@...r.kernel.org, boris.ostrovsky@...cle.com Subject: [PATCH v3 6/9] xen/pvh: Initialize grant table for PVH guests Like PV guests, PVH does not have PCI devices and therefore cannot use MMIO space to store grants. Instead it balloons out memory and keeps grants there.
