Configuration snooping bridge

摘要

Systems and methods for configuration snooping are provided. A bridge identifies an initialization message of a central processing unit (CPU) for a device that is downstream of a primary interface of the bridge. The bridge identifies a response to the initialization message. The bridge determines the address range for the device. The bridge stores the address range for the device in a list in the bridge.

主权项

1. A method, comprising:
identifying, by a processing device of a bridge in a computing system, an initialization message of a central processing unit (CPU) for a device, the device being connected to a secondary interface of the bridge; identifying, by the processing device, a device response to the initialization message; determining, by the processing device, an address range for the device in view of the initialization message and the device response; storing the address range for the device in a list in the bridge; and enabling, by the processing device, access to the device in view of the list in the bridge before the bridge receives a system list from the CPU.
