-3) Supporting multiple types of IOMMUs
-
- If your architecture needs to support multiple types of IOMMUs, you
- can use include/linux/asm-generic/dma-mapping-common.h. It's a
- library to support the DMA API with multiple types of IOMMUs. Lots
- of architectures (x86, powerpc, sh, alpha, ia64, microblaze and
- sparc) use it. Choose one to see how it can be used. If you need to
- support multiple types of IOMMUs in a single system, the example of
- x86 or powerpc helps.
