2009-03-24intel-iommu: VT-d page table to support snooping control bitSheng Yang
The user can request to enable snooping control through VT-d page table. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2009-01-04intel-iommu: fix build error with INTR_REMAP=y and DMAR=nIngo Molnar
dmar.o can be built in the CONFIG_INTR_REMAP=y case but iommu_calculate_agaw() is only available if VT-d is built as well. So create an inline version of iommu_calculate_agaw() for the !CONFIG_DMAR case. The iommu->agaw value wont be used in this case, but the code is cleaner (has less #ifdefs) if we have it around unconditionally. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-03calculate agaw for each iommuWeidong Han
"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 <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

2008-10-18intel-iommu: IA64 supportFenghua Yu
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.
