Abstract: A method and apparatus for managing a controller includes indicating, by a processor of a first device, to the controller of a second device to enter a second power state from a first power state. The controller of the second device responds to the processor of the first device with a confirmation. The processor of the first device transmits a signal to the controller of the second device to enter the second power state. Upon receiving a wake event, the controller of the second device exits the second device from the second power state to the first power state.

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.

Abstract: Devices and methods for linear addressing are provided. A device is provided which comprises a plurality of components having assigned registers used to store data to execute a program and a power management controller, in communication with the components. The power management controller is configured to send one of a request to remove power to the components and a request to reduce power to the components when it is determined that the components are idle, execute a first process of one of removing power and reducing power to the components and entering a reduced power state when an acknowledgement of the request is received and execute a second process of restoring power to the components when one or more of the components are indicated to be active.

Abstract: Devices and methods for transitioning between power states of a device are provided. A program is executed using data stored in configuration registers assigned to a component of a device. For a first reduced power state, data of a first portion of the configuration registers is saved to the memory using a first set of linear address space. For a second reduced power state, data of a second portion of the configuration registers is saved to the memory using a second set of linear address space and data of a third portion of the configuration registers is saved to the memory using a third set of linear address space.

Abstract: Systems, methods, and devices for integrated circuit power management. A mode of a power management state is entered, from the power management state, in response to an entry condition of the mode. A device that is otherwise powered off in the power management state is powered on in the mode of the power management state. In some implementations, the device includes a communications path between a second device and a third device. In some implementations, the device is in a power domain that is powered off in the power management state. In some implementations, the power domain is powered off in the mode. In some implementations, the device is powered on in the mode via a power rail that is specific to the mode. In some implementations, the entry condition of the mode includes an amount of data stored for display in a display buffer falling below a threshold amount.

Abstract: Systems, apparatuses, and methods for implementing dynamic control of a multi-region fabric are disclosed. A system includes at least one or more processing units, one or more memory devices, and a communication fabric coupled to the processing unit(s) and memory device(s). The system partitions the fabric into multiple regions based on different traffic types and/or periodicities of the clients connected to the regions. For example, the system partitions the fabric into a stutter region for predictable, periodic clients and a non-stutter region for unpredictable, non-periodic clients. The system power-gates the entirety of the fabric in response to detecting a low activity condition. After power-gating the entirety of the fabric, the system periodically wakes up one or more stutter regions while keeping the other non-stutter regions in power-gated mode. Each stutter region monitors stutter client(s) for activity and processes any requests before going back into power-gated mode.
