APPARATUSES AND METHODS

Abrégé

An apparatus is provided. The apparatus comprises interface circuitry, machine-readable instructions, and processing circuitry to execute the machine-readable instructions to determine that a first composite link of a plurality of composite PCIe links terminating at the same PCIe root port lacks support for enabling a desired power saving state or an exit latency for the first composite link is above a first latency threshold. The processing circuitry is further configured to determine whether an exit latency for a second composite link of the plurality of composite PCIe links is below a second latency threshold and selectively trigger at least one sub-link of the second composite link to enable the desired power saving state if the exit latency for the second composite link is below the second latency threshold.
