| 2015-01-19 | iommu: add ARM LPAE page table allocator | Will Deacon | |
| A number of IOMMUs found in ARM SoCs can walk architecture-compatible page tables. This patch adds a generic allocator for Stage-1 and Stage-2 v7/v8 long-descriptor page tables. 4k, 16k and 64k pages are supported, with up to 4-levels of walk to cover a 48-bit address space.

| 2015-01-19 | iommu: introduce generic page table allocation framework | Will Deacon | |
| This patch introduces a generic framework for allocating page tables for an IOMMU. There are a number of reasons we want to do this: - It avoids duplication of complex table management code in IOMMU drivers that use the same page table format - It removes any coupling with the CPU table format (and even the architecture!) - It defines an API for IOMMU TLB maintenance Tested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Will Deacon <will.deacon@arm.com> | |||
