*	iommu/amd: Set IOTLB invalidation timeout	Joerg Roedel	2011-12-22
\| \| \| \| \| \| \| \|	To protect the command buffer from hanging when a device does not respond to an IOTLB invalidation, set a timeout of 1s for outstanding IOTLB invalidations. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Remove unnecessary cache flushes in amd_iommu_resume	Joerg Roedel	2011-12-22
\| \| \| \| \| \| \|	The caches are already flushed in enable_iommus(), so this flush is not necessary. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Add support for IOMMUv2 domain mode	Joerg Roedel	2011-12-12
\| \| \| \| \| \| \|	This patch adds support for protection domains that implement two-level paging for devices. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Put IOMMUv2 capable devices in pt_domain	Joerg Roedel	2011-12-12
\| \| \| \| \| \| \| \| \| \| \|	If the device starts to use IOMMUv2 features the dma handles need to stay valid. The only sane way to do this is to use a identity mapping for the device and not translate it by the iommu. This is implemented with this patch. Since this lifts the device-isolation there is also a new kernel parameter which allows to disable that feature. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Add iommuv2 flag to struct amd_iommu	Joerg Roedel	2011-12-12
\| \| \| \| \| \| \| \| \| \|	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.

*	iommu/amd: Enable GT mode when supported by IOMMU	Joerg Roedel	2011-12-12
\| \| \| \| \| \| \|	This feature needs to be enabled before IOMMUv2 DTEs can be set up. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Setup PPR log when supported by IOMMU	Joerg Roedel	2011-12-12
\| \| \| \| \| \| \|	Allocate and enable a log buffer for peripheral page faults when the IOMMU supports this feature. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Get the maximum number of PASIDs supported	Joerg Roedel	2011-12-12
\| \| \| \| \| \| \| \|	Read the number of PASIDs supported by each IOMMU in the system and take the smallest number as the maximum value supported by the IOMMU driver. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Convert dev_table_entry to u64	Joerg Roedel	2011-12-12
\| \| \| \| \| \| \| \|	Convert the contents of 'struct dev_table_entry' to u64 to allow updating the DTE wit 64bit writes as required by the spec. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu/amd: Move missing parts to drivers/iommu	Joerg Roedel	2011-06-21
	A few parts of the driver were missing in drivers/iommu. Move them there to have the complete driver in that directory. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
