    【重识云原生】第四章云网络4.7.4节vhost-user方案——virtio的DPDK卸载方案

    其计划支持对接的back-end的设备类型有:vhost-user、vhost-kernel、vhost-vdpa,此处仅结合vhost-user类型的back-end设备来进行介绍。 4.4.2 基于DPDK/SPDK的virtio back-end 驱动的用户态实现         virtio back-end设备用户态实现逻辑工作在Host系统的DPDK/SPDK进程中。 4.4.2.1 vhost-net back-end设备驱动实现         vhost-net的back-end设备实现逻辑在 “DPDK/examples/vhost” 和 “DPDK/driver 此处以“DPDK/examples/vhost”的实现为例来概述vhost-net back-end设备的相关工作流程: 1.设置vhost back-end处理函数并开启vhost server监听 4.4.2.2 vhost-vdpa back-end设备         vhost-vdpa back-end设备的实现流程大体与vhost-net/vhost-blk/vhost-scsi一致。

    从上到下的系统架构分析方法 - Intel PMU

    一般来说,CPU 流水线在概念上分为两部分,即前端(Front-end)和后端(Back-end)。 uOps 被分配给 Back-end 进行执行,Back-end 负责监控 uOp 的数据何时可用,并在可用的执行单元中执行 uOp。 Front-end 是 pipeline 的一部分,负责交付 uOps 给 Back-end 执行。 如果 pipeline 的 Back-end 部分不能接受更多操作(也称为 Back-end Stall),未使用的 pipeline slot 被分类为 Back-end Bound。 Back-end Bound Back-end Bound 分为 Memory Bound 和 Core Bound,通过在每个周期内基于执行单元的占用情况来分析 Back-end 停顿。
