摘要:
Methods and apparatus for integration of a processor and an input/output hub are described. In one embodiment, a sideband signal may cause change in a power management state of a processor or an integrated I/O logic. A single integrated circuit die may include both the processor and the integrated I/O logic. Other embodiments are also disclosed.

Methods and apparatus for throttling an interface that is integrated on the same die as a processor are described. In one embodiment, a signal from an Integrated Input/Output hub (e.g., integrated on the same die as a processor) causes throttling of a link coupled between the IIO and an Input/Output (IO) device. Other embodiments are also disclosed.

Machine-readable media, methods, and apparatus are described for processing coherent requests of a computing device comprising multiple cache nodes. In some embodiments, a coherent switch may receive from a requesting cache node a coherent request for a line of memory. The coherent switch may further issue snoop requests to one or more non-requesting cache nodes based upon whether a snoop filter bypass mode is enabled. In particular, the coherent switch when not in snoop filter bypass mode may obtain coherency data from a snoop filter and may issue snoop requests to zero or more non-requesting cache nodes based upon the coherency data obtained from the snoop filter. Further, the coherent switch when in snoop filter bypass mode may bypass the snoop filter and may issue snoop requests to all non-requesting cache agents.
摘要:
A computer system includes a priority arbitration scheme that prevents "hogging" of a bus by a priority agent. The computer system comprises at least one agent, at least one priority agent, a system resource, and a bus coupling the agent, priority agent, and system resource to one another. An arbiter is coupled to the bus, agent, and priority agent to receive request signals from the agent and the priority agent and to grant control of the bus to one of the agent and priority agent for access to the system resource. The priority agent is granted control of the bus whenever the priority agent asserts a request signal, as soon as the bus becomes next available. The priority agent relinquishes control of the bus to the agent, for a predetermined portion of the bus bandwidth, when a request signal is asserted by the agent.

Methods and apparatus relating to device power management state transition latency advertisement for faster boot time are described. In some embodiments, a storage unit stores a value corresponding to a requisite transition delay period for a first agent to exit from a low power consumption state. The first agent writes the value to the storage unit and a second agent waits for the requisite transition delay period (after the first agent initiates its exit from the low power consumption state) before the second agent attempts to communicate with the first agent via a link. Other embodiments are also disclosed and claimed.
