  • Patent number: 8977871
    Abstract: A system comprises a plurality of processor cores. The processor cores may comprise one or more application processor (AP) cores and a boot strap processor (BSP) core. A basic input/output system (BIOS) comprises an I/O device module to call a stall function in response to an I/O operation, a power management module that couples to the I/O device and a timer module that couples to the power management module. The power management module is to adjust a timer period of the timer module based on a stall delay of the stall function. The power management module may hook the stall function and compare the stall delay with a predetermined threshold and set the timer period to the stall delay in response to determining that the stall delay is longer. The power management module may put the BSP in a sleep mode during the timer period to save power.

  • Patent number: 7941810
    Abstract: Improved reliability, availability, and serviceability (RAS) is provided by an extensible and flexible firmware architecture. The architecture provides management for events, where an event is a response to an imminent failure of or capacity change requirement applicable to a component of the system. In response to an event, control of a system is transferred from an operating system to the firmware manager. The manager identifies an action that is specified by the event. Based on the action, the firmware manager selects a firmware handler from a plurality of firmware handlers. The firmware manager dispatches the selected firmware handler to perform the specified action. The firmware manager and the dispatched firmware handler exchange system-independent information regarding the event. The firmware manager also manages time-slices for the performance of the specified action by the dispatched firmware handler.

  • Patent number: 7936703
    Abstract: A spanning tree is assigned to a processing node for each processing node in a point-to-point network that connects a plurality of processing nodes. The spanning tree uses the processing nodes as vertices and links of the network as edges. Each processing node includes input snoop ports that can be configured as either terminating or forwarding. According to the assigned spanning trees and the configuration of the input snoop ports, the network routes snoop messages efficiently and without conflicts.
