    摘要： A mechanism is provided for controlling operational parameters associated with a plurality of processors. A control system in the data processing system determines a utilization slack value of the data processing system. The utilization slack value is determined using one or more active core count values and one or more slack core count values. The control system computes a new utilization metric to be a difference between a full utilization value and the utilization slack value. The control system determines whether the new utilization metric is below a predetermined utilization threshold. Responsive to the new utilization metric being below the predetermined utilization threshold, the control system decreases a frequency of the plurality of processors.

    摘要： A mechanism is provided for controlling power management policies on a per logical partition basis. A power management mechanism in a data processing system receives a notification that the logical partition has been generated, a set of processing units associated with the logical partition, and a current power management policy to be implemented for the logical partition. The power management mechanism adds the logical partition and the set of processing units to a list of logical partitions. The power management mechanism initializes the set of processing units based on settings for the set of processing units in the current power management policy. The power management mechanism notifies a virtualization mechanism that the set of processing units are running at a specified performance level in order for the logical partition to start executing tasks on the set of processing units.

    摘要： A mechanism is provided for estimating energy/power consumption of a fixed-frequency operating mode while system is running in dynamic power management mode. For each time interval in a plurality of time intervals within a time period: a first processor identifies a modeled total nominal power value for at least one second processor during a current time interval, stores the modeled total nominal power value for the current time interval in a storage, identifies a dynamic power management mode power value for the at least one second processor in the data processing system during the current interval, and stores the dynamic power management mode power value for the current time interval in the storage. Responsive to the time period expiring, a comparison is produced of a plurality of modeled total nominal power values and a plurality of dynamic power management mode power values over the time period.

    摘要： A method, apparatus and computer instructions are provided for controlling communications between controller devices over an I2C bus hardware interface and a separate communication line, such as a GPIO line. With thermal/power management firmware installed on a system controller device, communications between the system controller device and a real time embedded controller device are sent using a predefined protocol whereby the system controller generates commands to the embedded controller by first performing an I2C write with a command packet, followed immediately thereafter by an I2C read to get the return packet. The embedded controller processes the command and returns the response to the I2C read. In addition, the embedded controller is able to make the system controller aware that it has a communication request by interrupting the system controller by asserting the separate communication line, in response to which the system controller issues a status request command to the embedded controller.

    摘要： A battery capacity test and electronic system implementing the same tests both the high and low discharge capacities of a back-up battery to ensure that the battery is capable of handling both a short term, high discharge load and a long term, low discharge load. The battery capacity test is particularly suitable for use in an electronic system which, upon occurrence of a power outage, converts from an operational mode to a power saving mode during a conversion time. High discharge capacity testing is performed using a "safety net" where the primary power source of the electronic system is switched to a reduced testing voltage output, rather than shut off or disconnected, so that the primary power source can take over quickly in the event of a back-up power supply failure during the test.
