struct nvme_command主要用于存储一个nvme命令,包括io命令,或者控制命令,当初始化好一个struct nvme_command后,直接将其下发给nvme设备,nvme设备就会根据它来执行对应操作,其结构如下: struct nvme_command { union { struct nvme_common_command common; struct nvme_rw_command rw; struct nvme_identify identify; ...
nvme 是 NVMe SSD和 NVMe oF 存储命令行管理工具,nvme安装包为 nvme-cli,它依赖Linux内核 IOCTL 系统调用,该调用连接用户层和NVMe驱动层,当用户执行 nvme commands 时,IOCTL 会将命令参数传递至 NVMe common 层,该层代码解析命令并执行命令,将命令封装至 capsule ,进而传递至 NVMe Submission 队列,Controller 处理...
