A logical partition debugger allows debugging one logical partition in a computer system without requiring the shutdown of other logical partitions. The logical partition debugger is implemented in software in the partition manager. The logical partition debugger provides many common debug functions known in existing hardware and software debuggers, but does so in a manner that only the partition being debugged is affected.

In a debugging circuit and a controlling method of the debugging circuit, a mode judgment signal is generated which indicates that a central processing unit (CPU) is preparing to debug a predetermined program. Responsive to the mode judgment signal, a monitoring signal is generated indicative of an attempt by the CPU to execute the predetermined program during the debugging preparation. Furthermore, a transfer of an instruction code corresponding to the predetermined program is controlled so tha...

A method and apparatus to insert special instruction. At least one of the illustrative embodiments is a method comprising converting a first representation of a computer program to a second representation, and inserting into the second representation a special instruction not needed to implement functionality in the first representation. The special instruction gives duplicate copies of the computer program executed in different processors an opportunity to service external asynchronous interrup...

Some aspects provide determination of a debug event, selection of a controller context based on the determined debug event, and execution of the selected controller context. The debug event may be associated with a microprocessor, and the controller context may be selected based on predetermined associations between a plurality of debug events and a plurality of controller contexts.

A method for testing a network device having modules for receiving and sending data packets in a network includes generating in the network device at least one internal data structure associated with a data packet received by the network device from the network. A predefined action on the network device is then preformed responsive to the internal data structure indicating that the data packet satisfies a predefined condition.

A debugging device and method are provided, including a central processing unit (CPU) connected to a chipset with a system management interrupt pin. The debugging method includes sending out a system management interrupt signal to central processing unit from the system management interrupt pin of the chipset. Then the CPU moves into a system management mode and pops out a debugging operation window for selecting and executing each debugging item. After the execution of each debugging item is co...

A program-controlled unit includes a core for executing the program to be executed by the program-controlled unit, and debug resources for tracking and influencing the operations proceeding within the core. The program-controlled unit is distinguished by the fact that the debug resources are able also to influence other components of the program-controlled unit and/or the cooperation of these components with one another and/or with the core. Such action makes it possible to avoid to the greatest...

A method and apparatus for managing error/status information generated in the demultiplexing, processing, and handling of data packets from a video transport stream. Error/status information is organized into control fields of error/status packets. The error/status packets are sent to dedicated error/status buffers of bulk system memory where they can be accessed by a system processor during the reconfiguration and decoding of video programming.

The present invention provides a breakpoint logic unit, debug logic and breakpoint method for a data processing apparatus. The breakpoint logic unit comprises a value storage operable to store data indicative of a selected value for an operational characteristic of the data processing apparatus, and comparator logic operable to compare the selected value with a value of the operational characteristic as generated by the data processing apparatus. The comparator logic then generates at least one ...

Under the present invention, a configurable dictionary is provided. The configurable dictionary includes a set of objects that identify: (1) attribute conditions of the computer system to be checked; (2) associated locations within the computer system for checking the attribute conditions; and (3) actions to be taken based on results of the checks for the computer system. The health of the computer system is checked by processing the set of objects in the configurable dictionary. Specifically, t...
