WebFor example, if the PCIe address from EP after outbound translation is already translated to 0x12300000 and so on, then you may not need to enable inbound translation on PC side and just need to make sure PC could accept those PCIe address (from 0x12300000) and the PCIe transactions (write or read) will be applied to that memory region. WebJan 9, 2014 · Figure 4 shows an example of a PCIe switch and endpoint devices in a PCIe device tree topology. Figure 4 shows that the PCIe switch is composed of three connected “virtual” (logical) PCI-to-PCI bridges. The switch has one inbound port (called an ingress port in PCIe) and two outbound ports (called egress ports in PCIe). There are two ...

Chek, First of all, there could be different understanding of the inbound vs outbound. In the C66x PCIe documentations, outbound transaction means the local device initiates the PCIe transfer (no matter write or read) and inbound transaction means the remote device initiates the PCIe transfer (no matter write or read). dave cockerham
