Abstract
A method for accessing a configuration space of a device is described. The method includes setting a first field of a packet to a value to specify a destination device, and setting a second field of the packet to a defined value to indicate that the packet is a configuration access packet. The method further includes setting a third field of the configuration access packet to a value to select one of a plurality of configuration apertures of a configuration space of the destination device, and setting a fourth field of the configuration access packet to a value to address a specific memory location within the selected aperture.
