摘要： A method and system for managing peripheral connection wakeup signaling in a processing system supporting multiple virtual machines provides a mechanism by which ownership of a peripheral having system wakeup capability is transferred between virtual machines. The power management event signal is connected to a service processor input that in turn signals a hypervisor to direct the wakeup activity to a particular logical partition in which the virtual machine was last executing. The hypervisor can then determine whether or not to wake up the entire system, or portions thereof and can direct the power management event to the appropriate virtual machine. In particular the peripheral may be an Ethernet adapter supporting Wake-On-LAN capability. State initialization, which is typically ensured by system power cycling is provided instead by controlling power to the standby power source or in some instances by forcing an indication of a disconnect/reconnect of the wakeup signaling connection.

摘要： A method, apparatus and computer program product are provided for implementing time synchronization correction in computer systems. A service processor includes a battery-backed hardware clock, and a hypervisor includes a hypervisor system clock. A common timer resource is accessible by the hypervisor and the service processor. To synchronize the battery-backed hardware clock and the hypervisor system clock, the common timer resource is used to measure the latency in the communication medium between the hypervisor and the service processor. The latency is then added onto the time value received in time of day messages between the hypervisor and the service processor for time synchronization correction in the computer systems.
