Abstract: One or more triggers may be coupled to sources on a system on a chip of a portable computing device. The sources monitor the system for status conditions. The one or more triggers are coupled to a trigger bus. A sequencer engine is coupled to the trigger bus and a communication bus. The sequencer engine receives one or more instructions from the communication bus for determining how the sequencer engine should monitor the one or more triggers via the trigger bus and preserve data received from the one or more triggers before a system reset. The sequencer engine then receives data from the one or more triggers and stores the data in local memory storage. The sequencer engine, if programmed, may generate at least one of a trace packet, an interrupt signal, and a general purpose input/output signal in response to receiving data from one or more triggers.

Abstract: A test apparatus applicable to a server includes a processing unit, a control unit, a switch unit and a power relay unit. The processing unit outputs a reset signal and a processing signal. The control unit includes a first physical layer chip performing a first communication protocol, and a second physical layer chip performing a second communication protocol. The switch unit receives a working voltage and a processing signal to select a powering signal or a disconnection signal to output. The power relay unit receives the powering signal or the disconnection signal. When the power relay unit receives the powering signal, the server performs a test task on the first physical layer chip. When the power relay unit receives the disconnection signal and the processing unit outputs the reset signal to the control unit, the server performs the test task on the second physical layer chip.

Abstract: A system firmware agent providing the capabilities of a Baseboard Management Controller (BMC) from within System Management Mode (SMM) is discussed. A virtual BMC provides dedicated communication channels for system firmware, other BMCs in the platform and remote management agents. The virtual BMC may monitor the status of the system, record system events, and control the system state.

Abstract: This disclosure presents systems and methods for run-time analysis of streams of log data for abnormalities using a statistical structure of meta-data associated with the log data. The systems and methods convert a log data stream into meta-data and perform statistical analysis in order to reveal a dominant statistical pattern within the meta-data. The meta-data is represented as a graph with nodes that represent each of the different event types, which are detected in the stream along with event sources associated with the events. The systems and methods use real-time analysis to compare a portion of a current log data stream collected in an operational window with historically collected meta-data represented by a graph in order to determine the degree of abnormality of the current log data stream collected in the operational window.

Abstract: Systems and methods are described for generating a test executable used for testing an application locally on a host device. A user interface allows selection of particular test modules for use. Based on the selected modules a test executable is generated. The test executable functionality may integrated with the application or be independent of the application. The host device executes the test executable which enables testing and debugging on the local device.

Abstract: Managing synchronized data requests is disclosed. Examples of synchronized data requests include viewer-induced synchronization, failure-induced synchronization, and player-induced synchronization. Information indicative of the potential occurrence of a detrimental amount of synchronized requests in a content delivery infrastructure is received. One or more remediation actions is automatically caused to occur.

Abstract: A network system comprising logical work and protect Connection Termination Points. Performance Monitoring (PM) records are provided by generating for each work Connection Termination Point (CTP) a work bit vector and a protect bit vector. The work bit vector keeps track of severely errored seconds (SES) occurrences at the work CTP only when the work CTP is selected. The protect bit vector keeps track of severely errored seconds (SES) occurrences at the protect CTP only when the protect CTP is selected. Processing the work bit vector and the protect bit vector provides accurate PM records.

The flash memory device includes a plurality of memory blocks, each including a plurality of memory cells.

Abstract: A database system may implement database cache survivability across database failures. In various embodiments, a database cache may be maintained independent of a failure of a database. A database cache may be maintained in a non-volatile memory device or maintained in a shared memory segment of system memory. Upon recovery from a database failure, a recovery point may be determined that indicates a consistent state of the database. Cache entries of the database cache inconsistent with the consistent state of the database may be invalidated, and the database cache may be made available for access requests directed toward the database. Valid cache entries from before the database failure may be made available without accessing a back-end data store for the database.

Abstract: Fault tolerant operation is disclosed for a primary instance, such as a process, thread, application, processor, etc., using an active copy-cat instance, a.k.a. backup instance, that mirrors operations in the primary instance, but only after those operations have successfully completed in the primary instance. Fault tolerant logic monitors inputs and outputs of the primary instance and gates those inputs to the backup instance once a given input has been processed. The outputs of the backup instance are then compared with the outputs of the primary instance to ensure correct operation. The disclosed embodiments further relate to fault tolerant failover mechanism allowing the backup instance to take over for the primary instance in a fault situation wherein the primary and backup instances are loosely coupled, i.e. they need not be aware that they are operating in a fault tolerant environment.

The first system and second system process the input and each generates output. The output from the first system and second system is analyzed and differences in the output data between the two systems are identified.

Abstract: A method for automatically testing an apparatus controlled by software based on pilot test case file comprising user input sequence data recorded manually and the time stamp of the input. In the process of automated testing, these pre-recorded user inputs are replay with same input sequence but with either the same time interval between two subsequent inputs recorded prior; or with a random time interval autonomously generated in a range set by the test configuration. During the process of replaying user input, a separate plural numbers of background tasks are executed in parallel with random execution delays to generate varying system load and execution timing to simulate the apparatus' unpredictable real operation scenarios. The user input and new random time interval between each user input are recorded at replay as a new expanded test record file for later test result trace and failure analysis.
