Subject: [PATCHv7 02/26] iommu: add capability IOMMU_CAP_NOEXEC
Date: Tue, 23 Sep 2014 16:46:01 +0200	[thread overview]
Message-ID: <1411483586-29304-3-git-send-email-a.motakis@virtualopensystems.com> (raw)
In-Reply-To: <1411483586-29304-1-git-send-email-a.motakis@virtualopensystems.com>

Some IOMMUs accept an IOMMU_NOEXEC protection flag in addition to
IOMMU_READ and IOMMU_WRITE. Expose this as an IOMMU capability.
