-config CALGARY_IOMMU
- bool "IBM Calgary IOMMU support"
- select IOMMU_HELPER
- select SWIOTLB
- depends on X86_64 && PCI
- ---help---
- Support for hardware IOMMUs in IBM's xSeries x366 and x460
- systems. Needed to run systems with more than 3GB of memory
- properly with 32-bit PCI devices that do not support DAC
- (Double Address Cycle). Calgary also supports bus level
- isolation, where all DMAs pass through the IOMMU. This
- prevents them from going anywhere except their intended
- destination. This catches hard-to-find kernel bugs and
- mis-behaving drivers and devices that do not use the DMA-API
- properly to set up their DMA buffers. The IOMMU can be
- turned off at boot time with the iommu=off parameter.
- Normally the kernel will make the right choice by itself.
- If unsure, say Y.

- Should Calgary be enabled by default? if you choose 'y', Calgary
- will be used (if it exists). If you choose 'n', Calgary will not be
- used even if it exists. If you choose 'n' and would like to use
- Calgary anyway, pass 'iommu=calgary' on the kernel command line.
