运行时电源管理当前对非-雷电热拔插端口是禁止的,因为当非雷电热拔插端口在D3hot状态时可能引起诸如不可屏蔽的中断 (NMI)。厂商可以在命令行传递pcie_port_pm=force验证它们的热拔插端口是否支持运行时挂起,也许这个功能可能在晚些时候默认使能。 意外移除 ...
最近在研究Linux内核网口部分代码,除了CPU内部集成MAC,比较有意思的就是PCIE-Switch/Eth控制器了,利用MSI-X中断和DMA完成收发包,本次构建采用RealTek的RTL8111H-PCIE-Ethernet Controler,其内部集成了一对MAC和PHY,可以实现单个10/100/1000网络接口。 本次驱动构建的平台采用RK3568来实现,连接方式通过PCIE,数据收发通过...
