摘要： Embodiments of the invention relates to adding test access to a back-drilled vertical access interconnect (VIA) of a printed circuit board (PCB). A VIA is either formed or provided as an opening through layers of the PCB. The VIA is countersunk from one of the two openings to the PCB prior to plating to form a surface that can be used as a test target. The countersunk VIA is subject to plating so that the interior walls and surfaces of the VIA are covered with a conductive material. The plating is removed along the walls of the countersunk section of the VIA, so that the plating remains on the shoulders and the non-countersunk section of the VIA with the shoulder in communication with a trace internal to the PCB. The back-drilled VIA with the plating configuration provides an internal conducting surface for contact while mitigating interference associated with a VIA stub.

摘要： Embodiments of the invention relate to processing queries. A query operation to be performed on a table of data is translated into a series of bit level logical operations using expansion and/or saturation operations. A mask is created from the series of bit level logical operations. This mask is then simultaneously applied to multiple rows from the table of data.

摘要： The embodiments relate to processing a guest event in a hypervisor-controlled system. A guest event triggers a first firmware service for the guest event in firmware. The guest event is associated with a guest, a guest key, and with a guest state and protected guest memory accessible only by the guest and the firmware. The firmware processes information associated with the guest event. The processed information includes information of the guest state and the protected guest memory. A subset of the processed information is received by a hypervisor to process the guest event, and a non-received portion of the information is retained by the firmware. The hypervisor processes the guest event based on the received subset and sends a process result to the firmware triggering a second firmware service for the guest event. The firmware processes the process result together with the retained information to generate modification associated with the guest event. The firmware performs the generated modification associated with the guest event at the protected guest memory.

摘要： A firmware update method is provided for use in an information processing system powered by a power system. The power system is powered by an external power source and the power system includes a rechargeable battery and a controller. The method includes checking a power status of the rechargeable battery through the controller in response to a firmware update procedure. A power status of the rechargeable battery is determined to be sufficient to perform the firmware update procedure, and an insufficiency of the external power source to power the power system is determined. Power for the firmware update procedure is limited, through the controller, to the rechargeable battery.

摘要： Embodiments of the invention relate to tracking processor transactional read and write sets, thereby eliminating speculative mispredictions. Both non-speculative read set and write set indications are maintained for a transaction. The indications are stored in cache. In addition, load and write queues of addresses are maintained. The load queue of addresses relates to speculative members of a read set and the write queue of addresses relates to speculating member of a write set. For a received read request, a transaction resolution process takes place, and a resolution is performed if an address match in the write queue is detected. Similarly, for a receive write request the transaction interference additionally checks the load queue and the non-speculative read set for the pending address.

摘要： Embodiments relate to a new application program interface (API) and supporting tools to introduce efficiency associated with a transaction. An in-memory translation table maintains accurate address locations of key-value pair locations. The new API employs the translation table to obtain both the requested data and any updated address associated with the requested data. Any subsequent API may be communicated with the updated address.

摘要： A universal power outlet, a universal junction box associated with a cover, and a universal extension cord. Sensors within openings in electrical sockets detect different characteristics of plug contacts. In response to the detected characteristics, power requirements for an energy consuming device associated with the plug are correlated. Logic dynamically selects and delivers a level of required power, from multiple available levels of power, to the device based on the detected characteristics.

摘要： Embodiments relate to data storage media, and reading data from the media and writing data to the media. A data structure is provided to identify storage location and/or media parameters. One or more parameters of storage media is pre-loaded and conveyed to an associated media accessor prior to transferring data across the storage media in support of an associated read or write request.

摘要： Efficient production testing of integrated circuits (ICs). A first production test is implemented on a group of ICs and failures among the test group are assessed. Specifically, the results of the first test are analyzed such that ICs having a recoverable fail and ICs having a non-recoverable fail are differentiated. The ICs are integrated based on the analyzed results and a second production test is implemented. The second production test tests the ICs responsive to the segregation, such that the second production test is limited only to ICs with a recoverable fail. The next succeeding production test will then use the new test program in the second production test with the handler bin designated as having ICs not to be re-tested.

摘要： A power supply system is provided to control one or more power supply units associated with an information handling system. A first power supply unit and a second power supply unit are electrically coupled to the information handling system. A controller is provided in communication with both the first and second power supply units. The controller functions to select one of the first and second power supply units to electrically power the information handling system. The non-selected unit generates zero output.
