至此PCIe硬件初始化已经全部完成,接下来就是主机软件对设备的处理,主要是设备的枚举以及资源分配,设备设置等。 从Trace中看到主机下发的第一个TLP报文,配置读取设备的Device ID,这表明主机软件已经开始接管PCIe设备了。参见图11。 关于主机软件对PCIe的初始化,我们暂且跳过,这是对所有PCIe设备的通用流程,接下来我们直接...
NVMe SSD底层使用PCIe总线,可以说PCIe总线是NVMe SSD的“高速公路”,NVMe SSD硬件同时实现了PCIe协议和NVMe协议,因此上电初始化分为两步,首先是PCIe层的初始化,只有在PCIe初始化成功“路”通了以后,才进行第二步NVMe层的初始化。 注意:下面的PCIe初始化阶段的“盘”可以理解为任意的PCIe end point device,例如网...
