2012-01-23	iommu/amd: Set IOTLB invalidation timeout	Joerg Roedel
	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>
2012-01-23	iommu/amd: Remove unnecessary cache flushes in amd_iommu_resume	Joerg Roedel
	The caches are already flushed in enable_iommus(), so this flush is not necessary. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Add support for IOMMUv2 domain mode	Joerg Roedel
	This patch adds support for protection domains that implement two-level paging for devices. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Put IOMMUv2 capable devices in pt_domain	Joerg Roedel
	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.

2012-01-23	iommu/amd: Add iommuv2 flag to struct amd_iommu	Joerg Roedel
	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. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Enable GT mode when supported by IOMMU	Joerg Roedel
	This feature needs to be enabled before IOMMUv2 DTEs can be set up. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-01-23	iommu/amd: Setup PPR log when supported by IOMMU	Joerg Roedel
	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>
2012-01-23	iommu/amd: Get the maximum number of PASIDs supported	Joerg Roedel
	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>
2012-01-23	iommu/amd: Convert dev_table_entry to u64	Joerg Roedel
	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>
2011-06-21	iommu/amd: Move missing parts to drivers/iommu	Joerg Roedel
	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>
