    Abstract: Techniques for firmware providing a simulated system management mode (SMM) while being executed by a non-x86 platform, such as an ARM platform. In response to receiving a service call from an OS interface driver, the firmware may determine a requested service identified by the service call. Thereafter, the firmware may identify an appropriate service handler to perform the requested service. After the appropriate service handler performs the requested service, the appropriate service handler notifies the OS interface driver. Since the SMM is emulated by the firmware, the firmware may execute on an x86 platform or a non-x86 platform, such as an ARM platform.

  • Patent number: 9043553
    Abstract: Various technologies and techniques are disclosed for using transactional memory hardware to accelerate virtualization or emulation. State isolation can be facilitated by providing isolated private state on transactional memory hardware and storing the stack of a host that is performing an emulation in the isolated private state. Memory accesses performed by a central processing unit can be monitored by software to detect that a guest being emulated has made a self modification to its own code sequence. Transactional memory hardware can be used to facilitate dispatch table updates in multithreaded environments by taking advantage of the atomic commit feature. An emulator is provided that uses a dispatch table stored in main memory to convert a guest program counter into a host program counter. The dispatch table is accessed to see if the dispatch table contains a particular host program counter for a particular guest program counter.

  • Patent number: 8838867
    Abstract: A means for extending a PCI System of a host computer via software-centric virtualization. A Root Complex is virtualized at the host computer, and physically separated with a portion located remotely at an Endpoint, such as at a Remote Bus Adapter. One aspect of the invention avoids the need for a Host Bus Adapter. The invention utilizes 1 Gbps-10 Gbps or greater connectivity via the host's existing standard LAN adapter along with unique software to form the virtualization solution. The invention works within a host's PCI Express topology, extending the topology by adding an entire virtual I/O hierarchy via virtualization. The invention enables I/O virtualization in those implementations where a specialized host bus may not be desirable or feasible. Some examples of this may be a laptop computer, an embedded design, a cost-sensitive design, or a blade host where expansion slots are not available or accessible.

  • Patent number: 8813070
    Abstract: This invention is intended to reduce the hypervisor overhead. In the data processor disclosed herein, when a device driver calls for access to a control register to activate a process of a dedicated controlled peripheral device, the access is handled directly without intervention of processing by the hypervisor. When an interrupt is generated from a dedicated controlled peripheral device, a process is directly initiated by the device driver of the operating system governing the peripheral device without intervention of processing by the hypervisor. By implementing this manner of control in the processor, it becomes possible to carry out peripheral device control without intervention of processing by the hypervisor. Thereby, the hypervisor overhead is alleviated.

  • Patent number: 8812287
    Abstract: A method and device for preserving the wired-OR nature of the clock signal connection between two devices without a direct analog connection between the lines and in an infinitely scalable fashion. The method includes detecting a logic state at a first connector and a second connector and driving an appropriate connector of the device to an active state in response to determining that a connector is driving an active state. The device includes first and second connectors for communicating logic states and driving active states in response to detected logic states.

  • Patent number: 8805667
    Abstract: A print control device includes: a creation unit that creates print data; an output unit that outputs the print data created by the creation unit to a printing device through a designated port; a determination unit that determines whether or not the print data is to be output to a non-connected port that is a port not connected to the printing device; and a display unit which, when the determination unit determines that the print data has been output to the non-connected port, displays at least one of a first operation screen that is an operation screen for instructing port switching and a second operation screen that is an operation screen for instructing deletion of the print data.

    Abstract: A node on a serial bus, preferably a device such as a personal computer (PC), can emulate other devices using virtual device drivers. A PC connected to a 1394 bus exposes its CROM on the bus which presents an image to other nodes on the 1394 bus and describes the functional units supported by the node. The CROM can be changed dynamically by adding unit directories to the CROM detailing peripherals connected to the PC. The PC can then be enumerated as the connected device by other PCs on the bus. The PC can emulate or morph itself into any desired device or even multiple devices at the same time. The invention also allows a PC to create devices that don't yet exist on the bus. The invention allows a user to create virtual device objects with device properties to have just in case a user plugs the particular device in to the PC.

  • Patent number: 8798969
    Abstract: An enterprise database is accessed through semantic labels to develop models that enhance the database. A database of business objects is accessed, the business objects including data tables that relate semantic labels to enterprise data. One or more rules that use the semantic labels are applied to select enterprise data corresponding to the semantic labels. The selected enterprise data are used to determine modeling parameters that relate a semantic-label input set to a semantic-label output set, the semantic-label input set and the semantic-label output set each including at least one of the semantic labels. The modeling parameters are used to generate a simulation table that predicts an operational range of at least one business object corresponding to at least one of the semantic labels. The at least one business object is augmented in the database by including the simulation table in the at least one business object.

  • Patent number: 8793108
    Abstract: A three-dimensional model is determined from a two-dimensional sketch. Rather than or in addition to modification of 3D constraints to reduce gaps in the 3D model, 2D constraints are modified. The geometry of the 2D sketch is altered in the view plane (x, y) or 2D input instead of maintaining the geometry of the 2D sketch and only modifying in the view direction (z). Gaps may be reduced through alteration of the 2D geometry.

  • Patent number: 8789069
    Abstract: Various aspects are disclosed herein for replacing the hardware backing the memory locations associated with a virtual machine with a backing mechanism. The backing mechanism may have the memory locations appear to contain data convenient to the driver in the virtual machine, typically containing what the hardware would have returned if the hardware had been read from. The data image being returned from the memory locations may travel with the virtual machine even if the virtual machine moves to a different physical machine that does not contain hardware equivalent to the hardware that was recently removed from the virtual machine.
