15 bool "IOMMU Hardware Support"
26 menu "Generic IOMMU Pagetable Support"
40 sizes at both stage-1 and stage-2, as well as address spaces
41 up to 48-bits in size.
47 Enable self-tests for LPAE page table allocator. This performs
48 a series of page-table consistency checks during boot.
57 Enable support for the ARM Short-descriptor pagetable format.
58 This supports 32-bit virtual and physical addresses mapped using
59 2-level tables with 4KB pages/1MB sections, and contiguous entries
60 for 64KB pages/16MB supersections if indicated by the IOMMU driver.
66 Enable self-tests for ARMv7s page table allocator. This performs
67 a series of page-table consistency checks during boot.
86 bool "Export IOMMU internals in DebugFS"
89 Allows exposure of IOMMU device internals. This option enables
90 the use of debugfs by IOMMU drivers as required. Devices can,
91 at initialization time, cause the IOMMU code to create a top-level
92 debug/iommu directory, and then populate a subdirectory with
