第一个IOMMU实例,IOMMU 0(与IO桥0关联),将根端口与系统织物/互连接口相连。一个或多个端点设备通过这个根端口与SoC接口。在PCIe的情况下,根端口包含了一个用于IOMMU的ATS接口,该接口用于支持IOMMU的PCIe ATS协议。示例显示了一个端点设备,该设备有一个设备侧ATC(DevATC),它保存了设备通过PCIe ATS协议从IOMMU 0...
FENCE 指令提供的存储排序和原子指令的获取/释放位也对 IOMMU 观察到的与 这些存储相关的数据结构更新进行排序。 软件可使用 IOFENCE.C 命令来确保之前从 CQ 获取的所有命令都已完成并提交。IOFENCE.C 命令中的 PR 和/或 PW 位可设置为 1,以请求将 IOMMU 已处理过的所有先前读取和/或写入请求作为 IOFENCE.C...
We integrated the IOMMU IP into a [CVA6-based SoC](https://github.com/zero-day-labs/cva6/tree/feat/iommu) with support for the RISC-V hypervisor extension v1.0, along with a configurable number of instances of the [PULP iDMA](https://github.com/pulp-platform/iDMA) module to issue ...
Andrea:在GitHub上有一个Android特别兴趣小组(SIG)和一个Android RISC-V 64项目,围绕RISC-V支持Android开展大量活动。现在市场上新的芯片都支持RVV 1.0向量扩展。我们也开始看到使用这些向量扩展的开发板,如Banana Pi和Deep Computing DC-Roma II笔记本电脑。从开发人员的角度来看,这一点非常有价值,因为在目标...

If an IOMMU domain was never attached, it lacks any linkage to the actual IOMMU hardware. Attempting to do flush_iotlb_all() on it will result in a NULL pointer dereference. This seems to happen after the recent IOMMU core rework in v6.4-rc1. Unable to handle kernel read from unreadable...
