A memory block is provided that is shared between two endpoints. This first endpoint is either a host for a virtual machine or the virtual machine. The second endpoint is either the host or another virtual machine. The shared memory block includes a buffer, a post counter, and an acknowledgment counter. The block is employed for communicating data from the first endpoint to the second endpoint. Sending data to the second endpoint includes identifying the buffer as being currently owned by the first endpoint and storing data in the buffer. It is then detected that the acknowledgment counter is equal to the post counter. The post counter is then incremented to signal that data has been stored for receipt by the second endpoint. Receiving the data by the second endpoint includes detecting that the post counter has changed and then incrementing the acknowledgment counter to acknowledge receipt of the data.

Sharing data by a virtual machine

A system and method for vehicle energy management are described that take driving context into account to derive suggested vehicle control inputs to reduce energy consumption. Driving context may be based on information including, for example, traffic congestion and/or flow information for a traveled route, road topology information, traffic controls, weather conditions, vehicle characteristics, and other types of driving context information. The driving context may be used to derive suggested control inputs to reduce energy consumption. The suggested control inputs can, for example, be expressed as: a suggested road speed, suggested gear selection, rate of acceleration or rate of deceleration.

A system and method are provided for playing a media stream while a media system starts up. Media hardware, such as a display controller, may play media. A media driver may initialize the media hardware. A media module may receive the media stream from a media source. The media module and the display driver may start up before startup of the media system completes. The media module may provide the media stream directly or indirectly to the media hardware before and after startup of the media system completes without an interruption in playing of the media stream.
