配置软件唯一知道的是在根联合体内存在着主机/PCI桥,总线0直连到该桥的下游。由于还没有扫描过总线0,因此系统不知道在根联合体上存在着多少个PCIe端口。扫描PCIe结构以找出其拓扑的进程称为枚举(enumeration)。1.12.2 每种功能实现一组配置寄存器当处理器执行软件...
PCIe hotplug in Linux is facilitated by the PCI Hotplug subsystem, which manages the hotplug events and device enumeration. The PCI Hotplug subsystem communicates with the PCIe switch and the kernel's device driver model to properly handle hotplug events. One challenge with PCIe hotplug in Linux i...

linux PCI 5.18变更 简介 当前处于linux 内核5.18的合入窗口,本文介绍熟悉的PCI子系统的变更。 变更点 Enumeration: - Move the VGA arbiter from drivers/gpu to drivers/pci because it's PCI-specific, not GPU-specific… 阅读全文 PCI总线0,设备20、功能3这是啥意思呀?
Regarding to Linux PCIe bus enumeration, there are some spaces allocated by RC, when EP device is enumerated by PCIe RC. Can you try the following method, then check the PCIe EP inbound operations can be excuted or not?- Step1: find the memory space allocated by RC when iMX6 PCIe EP ...
