Subject: [RFC PATCH v6 04/20] iommu/arm-smmu: add capability IOMMU_CAP_INTR_REMAP
Date: Thu, 5 Jun 2014 19:03:12 +0200 [thread overview]
Message-ID: <1401987808-23596-5-git-send-email-a.motakis@virtualopensystems.com> (raw)
In-Reply-To: <1401987808-23596-1-git-send-email-a.motakis@virtualopensystems.com>
With an ARM SMMU, interrupt remapping should always be safe from the
SMMU's point of view, as it is properly handled by the GIC.
