2009-01-03Change intel iommu APIs of virtual machine domainWeidong Han1-9/+11
These APIs are used by KVM to use VT-d Signed-off-by: Weidong Han <[email protected]> Signed-off-by: Joerg Roedel <[email protected]>
2009-01-03calculate agaw for each iommuWeidong Han1-0/+1
"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: Weidong Han <[email protected]> Signed-off-by: Joerg Roedel <[email protected]>
2009-01-03intel-iommu: remove some unused struct intel_iommu fieldsMark McLoughlin1-5/+0
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.

2008-10-18intel-iommu: IA64 supportFenghua Yu1-16/+23
The current Intel IOMMU code assumes that both host page size and Intel IOMMU page size are 4KiB. The first patch supports variable page size. This provides support for IA64 which has multiple page sizes. This patch also adds some other code hooks for IA64 platform including DMAR_OPERATION_TIMEOUT definition.

2008-10-17dmar: Use queued invalidation interface for IOTLB and context invalidationYouquan Song1-0/+8
If queued invalidation interface is available and enabled, queued invalidation interface will be used instead of the register based interface. According to Vt-d2 specification, when queued invalidation is enabled, invalidation command submit works only through invalidation queue and not through the command registers interface.

2008-10-17dmar: context cache and IOTLB invalidation using queued invalidationYouquan Song1-0/+21
Implement context cache invalidate and IOTLB invalidation using queued invalidation interface. This interface will be used by DMA remapping, when queued invalidation is supported.
