  • Patent number: 11360884
    Abstract: A memory management system, such as a virtual memory manager that manages a virtual memory space that includes volatile memory (e.g. DRAM) and non-volatile memory (e.g., flash memory) creates a reserved portion of memory in the volatile memory for at least one user application in one embodiment, and that reserved portion can also store content that it restricted to read only permission within the non-volatile memory.

  • Patent number: 8621488
    Abstract: Techniques for intercommunication amongst device drivers are described herein. In one embodiment, an application programming interface (API) is provided by a kernel of an operating system (OS) running within a data processing system. The API is accessible by device drivers associated with multiple devices installed in the system. In response to a request from a first instance of a driver the API, information indicating whether another instance of the same driver is currently started is returned via the API. Other methods and apparatuses are also described.

  • Patent number: 8196153
    Abstract: Techniques for associating device drivers via a device tree are described herein. In one embodiment, a device tree having a hierarchical structure is maintained by a kernel of an operating system. The device tree includes device nodes corresponding to devices installed in a computer, including a first node and a second node. An auxiliary driver identifier is encoded within the first node for identifying a second device driver associated with the second node. The auxiliary driver identifier is used by a first device driver associated with the first node to invoke the second device driver to perform a predetermined operation on a device associated with the first node. Other methods and apparatuses are also described.

  • Patent number: 8094159
    Abstract: Methods and apparatuses for dynamic virtual frame buffer management. At least one embodiment of the present invention dynamically enables or disables the use of a virtual frame buffer, which is not under control of graphics hardware of a data processing system, without restarting the graphical user interface system (e.g., the window system) of the data processing system. For example, in response to the addition or removing of a frame buffer that is under control of a graphics controller (e.g., due to the activation or deactivation of the graphics controller, or the hot plug-in or hot disconnection of the graphics controller), the virtual frame buffer is disabled or enabled respectively.

  • Publication number: 20080261202
    Abstract: Polyfunctional reagents are disclosed that are capable of reversibly binding to target substances, for example nucleic acid, proteins, polypeptides, cells, cell components, microorganisms or viruses, for use in purifying or otherwise manipulating them. The reagents comprise a tagging group for manipulating and/or detecting the target substance when bound to the polyfunctional reagent. The polyfunctional reagents work by binding the target substance at a first pH and then releasing it at a second pH, usually higher than the first. Examples of tagging groups include tagging group members of a specific binding pair which is capable of binding to a specific binding partner and/or a label.

  • Publication number: 20070277051
    Abstract: One embodiment of the present invention provides a system that enables a computing device to save additional power by entering a “hibernation mode,” wherein the active state of the computing device is preserved in non-volatile storage while power to volatile storage is turned off. During operation, the system reanimates a computing device from a hibernation image by restoring reanimation code from the hibernation image and then executing the reanimation code. While executing this reanimation code, the system restores the rest of the hibernation image by, reading compressed data containing the rest of the hibernation image, and decompressing the compressed data using computational circuitry within the computing device. During this process, the decompression operations are overlapped with the reading operations to improve performance.
