至少必须支持其中一种模式。 当IOMMU 的 iommu_mode 字段值更改为 Off 时,IOMMU 保证连接到 IOMMU 的设备的处理中的(in-flight)事务将使用适用于 iommu_mode 字段旧值的配置进行处理,并且 IOMMU 已经处理过的所有事务和来自设备的先前请求将提交到全局排序点,以便平台中的所有 RISC-V 硬件、设备和 IOMMU 都能观...
As per the RISC-V AIA specification, since the number 0 is not a valid interrupt identity, the platform software is required to ensure that MSI data value assigned to a PCIe function is never 0. For e.g for a PCIe function which requests 16 MSI vectors the minimum MSI data value assign...
