Abstract: Embodiments herein describe using software or firmware to manage the device capability list of a PCIe device. That is, rather than relying on pure hardware to advertise the capabilities of a PCIe device, the embodiments herein permit software or firmware executing on a processor in the PCIe device to manage read and write requests associated with discovering the capabilities of the device and configuring the device.
