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.

This trivial patch adds support for i8k on the new Dell Vostro models. I tested it on my Vostro 1400, and it works. It does print a warning when loading the module: i8k: unable to get SMM BIOS version But I couldn't figure out how to fix that. The module seems to work fine, anyway...
