This API can be used by KVM for accessing different types of IOMMUs to do device passthrough to guests. Beside that this API can also be used by device drivers to map non-linear host memory into dma-linear addresses to prevent sgather-gather DMA. UIO may be another user for this API.

This patch introduces the API to abstract the exported VT-d functions for KVM into a generic API. This way the AMD IOMMU implementation can plug into this API later. Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

Impact: file renamed The code in the vtd.c file can be reused for other IOMMUs as well. So rename it to make it clear that it handle more than VT-d. Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

intel iommu APIs are updated, use the new APIs. In addition, change kvm_iommu_map_guest() to just create the domain, let kvm_iommu_assign_device() assign device. Signed-off-by: NWeidong Han <weidong.han@intel.com> Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

vm_domid won't be set in context, find available domain id for a device from its iommu. For a virtual machine domain, a default agaw will be set, and skip top levels of page tables for iommu which has less agaw than default.

virtual machine domain is different from native DMA-API domain, implement separate allocation and free functions for virtual machine domain. Signed-off-by: NWeidong Han <weidong.han@intel.com> Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

Because virtual machine domain may have multiple devices from different iommus, it cannot use __iommu_flush_cache. In some common low level functions, use domain_flush_cache instead of __iommu_flush_cache. On the other hand, in some functions, iommu can is specified or domain cannot be got, still use __iommu_flush_cache Signed-off-by: NWeidong Han <weidong.han@intel.com> Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

Add iommu reference count in domain, and add a lock to protect iommu setting including iommu_bmp, iommu_count and iommu_coherency. virtual machine domain may have multiple devices from different iommus, so it needs to do more things when add/remove domain device info. Thus implement separate these functions for virtual machine domain. Signed-off-by: NWeidong Han <weidong.han@intel.com> Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

In dmar_domain, more than one iommus may be included in iommu_bmp. Due to "Coherency" capability may be different across iommus, set this variable to indicate iommu access is coherent or not. Only when all related iommus in a dmar_domain are all coherent, iommu access of this domain is coherent.

"SAGAW" capability may be different across iommus. Use a default agaw, but if default agaw is not supported in some iommus, choose a less supported agaw. Signed-off-by: NWeidong Han <weidong.han@intel.com> Signed-off-by: NJoerg Roedel <joerg.roedel@amd.com>

The seg, saved_msg and sysdev fields appear to be unused since before the code was first merged. linux/msi.h is not needed in linux/intel-iommu.h anymore since there is no longer a reference to struct msi_msg. The MSI code in drivers/pci/intel-iommu.c still has linux/msi.h included via linux/dmar.h. linux/sysdev.h isn't needed because there is no reference to struct sys_device.
