Abstract: Methods and arrangements for devices to share a common address on a bus are disclosed. Embodiments may comprise a host for medium management and one or more client devices coupled with a communication medium. The host and/or one or more of the client devices may comprise devices capable of originating communications across the communication medium, also referred to as originating devices. Furthermore, the host and/or one or more of the clients may comprise devices capable of receiving communications via the communication medium, also referred to as receiving devices. An application may be capable of transmitting a command to request a response by one of two or more devices that share a common address. In particular, a driver for an originating device may receive an instruction from the application to send a command to the device and the device may recognize the command based upon a value associated with the command.

Abstract: A method and apparatus for user activity-based dynamic power management and policy creation for mobile platforms are described. In one embodiment, the method includes the monitoring of one or more sensor values of a mobile platform device to gather sensor activity data. Once the sensor activity data is gathered, the user state may be predicted according to the gathered user activity and an updated user state model. In one embodiment, the user state model is updated according to the sensor activity data. In one embodiment, a switch occurs from the present power management policy to a new power management policy if the new user state differs from a present user state by a predetermined amount. In one embodiment, at least one time-out parameter of a selected power management policy may be adjusted to comply with a predicted user state. Other embodiments are described and claimed.

Abstract: Methods and arrangements to negotiate a bit rate for a message of a communication on a multiple client communication medium such as a bus are disclosed. Embodiments may comprise a host for medium management and one or more client devices coupled with a communication medium. The host and/or one or more of the client devices may comprise devices capable of originating communications across the communication medium, also referred to as originating devices. Furthermore, the host and/or one or more of the clients may comprise devices capable of receiving communications via the communication medium, also referred to as receiving devices. Upon selecting a first bit rate, the originating device may transmit an address associated with one or more receiving devices that are the target of a communication. The originating device may then negotiate a second bit rate with the receiving device(s) to facilitate transmission of a message of the communication.

In an embodiment, the motherboard includes remote fan speed control module and a signal module, each to be coupled with a fan over a communication medium. The signal module is to transmit a signal over the communication medium indicating that the remote fan speed control module has exclusive control over fan speed of the fan.

Abstract: A system is provided with a basic input/output system (BIOS) with the ability to intervene, when a suspend process is initiated in response to an AC failure condition to place the system in a suspended to memory state, to initiate a number of data transfer operations to save a persistent copy of an operational state of the system. The BIOS is further equipped to check one or more times whether the data transfer operations are completed, and causing a processor of the system to operate in a reduced power consumption mode at least one time period while the BIOS is not performing the checking.

Abstract: A method and apparatus for facilitating power state control and awareness of an autonomous subsystem in a computer based system without involvement of the main operating system.

Abstract: According to some embodiments, encrypted and/or compressed system context information is stored when entering a low-power state.

Abstract: A system having a first device and a second device coupled to a single wire bus is described. The second device is operable to receive power from the single wire bus that is due to the first device driving the bus. The second device also communicates with the first device using the single wire bus.

Abstract: A method and apparatus for granting access to a hardware interface shared between multiple software drivers are described. In one embodiment, the apparatus includes an interface to provide access to a hardware function or a resource. As described herein, the hardware function or resource is shared between at least two software entities, such as, for example, device drivers. In one embodiment, access verification logic denies an access request for the hardware function, unless the key associated with the access request matches a stored key semaphore. In one embodiment, a key size may be relatively large to provide a very low probability that a malicious software entity could accidentally or maliciously gain access to the software. Other embodiments are described and claimed.

Abstract: A single wire bus communication system comprises a bus wire, a host device, and at least one client device, with each host and client device having pull-up and pull-down transistors to pull the bus wire “high” or “low”, respectively. The system is arranged such that, in response to a “trigger event” that requires responses from multiple client devices simultaneously, the host device enables its pull-down transistor, and each client device disables its pull-down transistor when conveying a “low” logic level onto the bus. To avoid bus contention, each client's pull-up transistor is arranged to conduct more current when enabled than the host's pull-down transistor. Then, one or more of the client devices' strong pull-ups will overcome the single weak pull-down on the bus, thereby enabling numerous client devices to respond to a command that requires a response from multiple clients.

Abstract: A requesting device sends a request, intended to read one or more device addresses on a bus. One or more sets of commands are then sent by the requesting device, where each set of commands is intended to read one device address. If, while a first device is writing its device address, the bus fails to display any of the driven values of the first address, because the second device is simultaneously writing a second address on the bus in response to the request, then the first device stops writing the first address. The first device does not write the first address again until after the second device has finished writing the second address.

Abstract: A method, apparatus and system to enable a data processing device to operate while seemingly “off”. According to one embodiment, a data processing device is configured to recognize a new system state, i.e., Visual Off. On such a data processing device, when the power button is pressed, the request to turn off the device is intercepted by a module and the device is transitioned to a Visual Off state. To the user, this transition appears instantaneous. During the transition, audible and visual indicators on the data processing device and on human interactive devices (“HID devices”) coupled to the data processing device may be turned off and/or disabled. While in the Visual Off state, the device may be fully operational, or in an alternate embodiment, the device may be placed in a low power state. When the user presses the power button again to “wake up” the data processing device, the device may transition from Visual Off into an “on” state (“Visual On”), i.e.
