iommu: Add a function to find an iommu group by id

2013-04-24T17:56:51Z

As IOMMU groups are exposed to the user space by their numbers, the user space can use them in various kernel APIs so the kernel might need an API to find a group by its ID. As an example, QEMU VFIO on PPC64 platform needs it to associate a logical bus number (LIOBN) with a specific IOMMU group in order to support in-kernel handling of DMA map/unmap requests. The patch adds the iommu_group_get_by_id(id) function which performs such search. v2: fixed reference counting.

iommu: Include linux/err.h

2013-04-19T19:05:10Z

The linux/iommu.h header uses ERR_PTR defined in linux/err.h but doesn't include it. Cc:joro@8bytes.org Reviewed-by: Alex Williamson Signed-off-by: Wang YanQing Signed-off-by: Joerg Roedel

iommu/fsl: Add the window permission flag as a parameter to iommu_window_enable API.

2013-04-02T16:20:53Z

Each iommu window can have access permissions associated with it. Extended the window_enable API to incorporate window access permissions. In case of PAMU each window can have its specific set of permissions. Signed-off-by: Varun Sethi Signed-off-by: Joerg Roedel

iommu/fsl: Make iova dma_addr_t in the iommu_iova_to_phys API.

2013-04-02T16:20:53Z

This is required in case of PAMU, as it can support a window size of up to 64G (even on 32bit). Signed-off-by: Varun Sethi Signed-off-by: Joerg Roedel

iommu: Add DOMAIN_ATTR_WINDOWS domain attribute

2013-02-06T09:47:28Z

This attribute can be used to set and get the number of subwindows on IOMMUs that are window-based. Signed-off-by: Joerg Roedel

iommu: Add domain window handling functions

2013-02-06T09:47:22Z

Add the iommu_domain_window_enable() and iommu_domain_window_disable() functions to the IOMMU-API. These functions will be used to setup domains that are based on subwindows and not on paging. Signed-off-by: Joerg Roedel

iommu: Implement DOMAIN_ATTR_PAGING attribute

2013-02-06T09:47:11Z

This attribute of a domain can be queried to find out if the domain supports setting up page-tables using the iommu_map() and iommu_unmap() functions. Signed-off-by: Joerg Roedel

iommu: Make sure DOMAIN_ATTR_MAX is really the maximum

2013-02-06T09:46:53Z

Move it to the end of the list. Signed-off-by: Joerg Roedel
