Subject: [PATCH 27/27] iommu/amd: Report irq remapping through IOMMU-API
Date: Wed, 11 Jul 2012 15:39:12 +0200	[thread overview]
Message-ID: <1342013952-10174-28-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1342013952-10174-1-git-send-email-joerg.roedel@amd.com>

Report the availability of irq remapping through the
IOMMU-API to allow KVM device passthrough again without
additional module parameter overrides.
