Abstract
Systems, apparatuses, and methods for enabling localized control of link states in a computing system are disclosed. A computing system includes at least a host processor, a communication fabric, one or more devices, one or more links, and a local link controller to monitor the one or more links. In various implementations, the local link controller detects and controls states of a link without requiring communication with, or intervention by, the host processor. In various implementations, this local control by the link controller includes control over the clock signals provided to the link. For example, the local link controller can directly control the frequency of a clock supplied to the link. In addition, in various implementations the link controller controls the power supplied to the link. For example, the link controller can control the voltage supplied to the link.
