Method and apparatus for reporting errors in a data processing system

A method for reporting errors occurring in a data processing system, the method comprising:

• responsive to an input/output error occurring in the data processing system, determining whether a host bridge is located between at least one of a resource that needs to be accessed to obtain error information and a processor and a host processor;
• responsive to determining whether a host bridge is located between at least one of a resource that needs to be accessed to obtain error information and a processor and a host processor, isolating the host bridge from other portions of the data processing system, wherein only a processor analyzing the input/output error is able to access the host bridge;
• clearing error in the host bridge;
• and
• gathering error data from at least one of the resource and the processor.

A data processing system for reporting errors occurring in the data processing system, the data processing system comprising:

• determining means, responsive to an error occurring in a host bridge in the data processing system, for determining whether a device required for generating an error report is located below the host bridge;
• isolating means, responsive to the device required for generating an error report being located below a host bridge, for isolating the host bridge from other portions of the data processing system, wherein only a processor analyzing the error is able to access the host bridge;
• and
• performing means for performing an error reporting process.

A data processing system comprising:

• a bus system;
• a memory connected to the bus system, wherein the memory includes a set of instructions;
• and
• a processing unit having a plurality of processors and being connected to the bus system, wherein the processing unit executes the set of instructions to determine whether a device required for generating an error report is located below the host bridge, in response to an error occurring in a host bridge in the data processing system;
• isolate the host bridge from other portions of the data processing system, wherein only a processor analyzing the error is able to access the host bridge, in response to the device required for generating an error report being located below a host bridge;
• and perform an error reporting process.
