At least, we could make something generic like struct iommu_functions, I think. Then we can embed a generic iommu structure into an iommu specific struct (like we do with inode). The current iommu-api (include/linux/iommu.h) is just about domain and mapping concept. We can implement it on the top of the above infrastructure. I'm still trying to figure out how the DMA-API can work well with them. -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
