This section demonstrates how to create extra PCIe root buses through extra Root Complexes. According to QEMU source code, PCIe features are supported only by 'q35' machine type on x86 architecture and the 'virt' machine type on AArch64. The root complex is created by using "pxb-pcie" on ...
PCIe Switch的upstream port与root complex之间的链接,是其downstream ports上的设备共享的;PCIe switch会根据upstream port的TLP(Transaction Layer Packet)中的地址信息,和downstream ports的type 1 configuration space中的配置信息,来路由TLP; 注:每个downstream port都有它自己的type 1 configuration space 对于一般的PC...
