Abstract:
A data processing system comprising:at least one processor having a processor test port; at least one memory coupled to said at least one processor; a service processor for managing said processing system having a service processor test port interfaced to said processor test port; and a register within said at least one processor coupled to said processor test port by a serial interface internal to said at least one processor, for allowing said service processor to exchange with an operating system executing within said at least one processor fault reporting and recovery information of a fault, wherein an indication of said fault is written into said register after said fault has been detected by said at least one processor for indicating a recovery action to said service processor, wherein said fault is a fault in a system component coupled to said at least one processor and said service processor directs a fault recovery within said system component in response to said indication, wherein said exchange of fault reporting and recovery information is made by said service processor sending commands via said service processor test port to said processor test port.
