The blog in question is lvyilong316, and it has 214 articles, 0 blog points, and 0 blog level. The user is a regular user who registered on January 23, 2013. The blog covers various topics related to Linux systems, including but not limited to networking, performance optimization, virtualization, and programming. The blog's archive includes articles from 2013 to 2025. The text also discusses the process of mapping resources for DPDK (Data Plane Development Kit) virtio-net using vfio and uio, as well as the differences between modern and legacy virtio PCI devices. The text also mentions the importance of opening IOMMU (Input/Output Memory Management Unit) in the VM for using vfio, and the differences in resource mapping for x86 and other architectures. The text concludes by discussing the differences in interrupt notifications for modern and legacy virtio PCI devices and the option to disable event_idx feature to avoid the need for frontend notification to the backend.本文内容涉及 9 月 30 日 14：00 至 10 月 4 日 08：00 期间，由于 Chinaunix.net 上的服务器迁移，在博客上发布内容暂时不可用。有问题的博客是 lvyilong316，它有 214 篇文章，0 个博客点，0 个博客级别。该用户是 2013 年 1 月 23 日注册的普通用户。该博客涵盖了与 Linux 系统相关的各种主题，包括但不限于网络、性能优化、虚拟化和编程。该博客的档案包括 2013 年至 2025 年的文章。本文还讨论了使用 vfio 和 uio 为 DPDK（数据平面开发套件）virtio-net 映射资源的过程，以及现代和传统 virtio PCI 设备之间的差异。文中还提到了在 VM 中打开 IOMMU（输入/输出内存管理单元）以使用 vfio 的重要性，以及 x86 和其他架构的资源映射差异。本文最后讨论了现代和传统 virtio PCI 设备的中断通知的差异，以及禁用event_idx功能以避免向后端发送前端通知的选项。 | |
