Subject: [PATCH v2 01/10] iommu/vt-d: Introduce native SVM capable flag
Date:   Mon, 18 Nov 2019 11:42:24 -0800
Message-Id: <1574106153-45867-2-git-send-email-jacob.jun.pan@linux.intel.com>
In-Reply-To: <1574106153-45867-1-git-send-email-jacob.jun.pan@linux.intel.com>
References: <1574106153-45867-1-git-send-email-jacob.jun.pan@linux.intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Shared Virtual Memory(SVM) is based on a collective set of hardware
features detected at runtime. There are requirements for matching CPU
and IOMMU capabilities.

This patch introduces a flag which will be used to mark and test the
capability of SVM.
