摘要： Technical solutions are described for executing a computer instruction including an asynchronous operation. An example method includes computing parameters associated with the asynchronous operation, and transmitting a command for executing the asynchronous operation by an external device. The method also includes intercepting and storing, by an interface logic controller, the parameters associated with the asynchronous operation into one or more log registers. The method also includes receiving a response to the asynchronous operation. In response to the asynchronous operation being a success, executing a next instruction by the processing element. In response to the asynchronous operation being a failure, a processing element accesses the parameters from the log registers, and restarts the asynchronous operation using the parameters from the one or more log registers.

摘要： Communication between one communication bus having one set of characteristics and another communication bus having another set of characteristics is facilitated by a bridge coupling the two communication buses. The bridge includes a scoreboard to manage data communicated between the buses. In one particular example, the one communication bus is a Processor Local Bus (PLB6) and the other communication bus is an Application Specific Integrated Chip (ASIC) Interconnect Bus (AIB).

摘要： Examples of techniques for transparent north port recovery of an error in an input/output device are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method may include: detecting, by a processing device, a command timeout; sending, by the processing device, an input/output (I/O) error signal to a host processing system connected to the hardware device via a north port of the hardware device; terminating, by the host processing system, a link between the north port of the hardware device and the host processing system; enabling, by the processing device, halt command forwarding on the hardware device; halting, by the processing device, commands upon detecting the halt command forwarding; and resetting, by the processing device, the link between the north port of the hardware device and the host processing system.

摘要： Embodiments relate to a method for encapsulating a hardware application for virtualization. The method surrounds the hardware application with a service layer controller and ring interfaces. The ring interfaces dictates a virtual function that the hardware application is running. The method controls the hardware application so that the hardware application is reset in between each of a plurality of running jobs. The method tags, by the ring interfaces, each of a plurality of requests with an identifier signifying a virtual function that the respective request belongs to. The method ensures that there are not any outstanding requests following a quiesce of the hardware application.

摘要： Embodiments relate to collecting extended error data from units within a programmable device. A pointer is accessed that points to a region of memory that contains a list of entries that references the extended error data. The list of entries is walked by adjusting a read pointer to obtain the extended error data. The referenced extended error data is moved to an event log.
