  • Debugging processor hang situations using an external pin
    Patent number: 9424165
    Abstract: Various aspects provide forced halt functionality for a processor to facilitate troubleshooting of processor hang situations. In the event that the processor initiates a transaction that does not receive a completion acknowledgement, a forced halt sequence can be initiated, which causes the processor to abort all pending transactions and transition to a debug state so that the internal state of the processor can be viewed. In addition, the processor can maintain a record of the processor state at the time that the hung transaction was dispatched, which can be viewed during debug mode to facilitate determining a cause of the hung transaction.
    Type: Grant

    Date of Patent: August 23, 2016

  • Processor hang detection and recovery
    Patent number: 9268627
    Abstract: Various aspects provide forced halt functionality for a processor to facilitate troubleshooting of processor hang situations. In the event that the processor initiates a transaction that does not receive a completion acknowledgement, halt detection logic can initiate a forced halt sequence that causes the processor to abort all pending transactions and transition to a debug state so that the internal state of the processor can be viewed. In addition, the processor can maintain a record of the processor state at the time that the hung transaction was dispatched, which can be viewed during debug mode to facilitate determining a cause of the hung transaction.
