[Qemu-devel] [PATCH v1 2/2] intel-iommu: Extend address width to 48 bits

2017-11-14 Thread prasad . singamsetty
From: Prasad Singamsetty The current implementation of Intel IOMMU code only supports 39 bits iova address width. This patch provides a new parameter (x-aw-bits) for intel-iommu to extend its address width to 48 bits but keeping the default the same (39 bits). The
