From: Joerg Roedel Date: Mon, 28 Nov 2011 14:11:02 +0000 (+0100) Subject: iommu/amd: Add iommuv2 flag to struct amd_iommu X-Git-Tag: v3.3-rc1~120^2~1^3~24 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=400a28a05f2cc1a311acb4ff6ac64d8402d21678;p=pandora-kernel.git iommu/amd: Add iommuv2 flag to struct amd_iommu In mixed IOMMU setups this flag inidicates whether an IOMMU supports the v2 features or not. This patch also adds a global flag together with a function to query that flag from other code. The flag shows if at least one IOMMUv2 is in the system.
