为IOMMU group 分配默认的 domain 失败,则检查下一个struct iommu_group,否则继续执行; 创建设备直接映射,这主要通过iommu_group_create_direct_mappings()函数完成; 连接设备和 IOMMU domain,这主要通过__iommu_group_dma_attach()函数完成; 完成系统 I/O 设备的 IOMMU 探测,这主要通过__iommu_group_dma_finalize...
解析dma-coherent属性(表示设备通过SMMU进行的DMA访问是否cache coherent的,假设DMA把外设的数据搬运到内存的某个位置,cpu去读那段地址,因为cache命中了,读到的还是旧的值,这就是cache的不coherent) staticintarm_smmu_device_dt_probe(structplatform_device*pdev,structarm_smmu_device*smmu){structdevice*dev=&pdev...
