In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing an error framework for a microprocessor and for a system having such a microprocessor. The error framework may alternatively be implemented by a hardware component, such as a peripheral device for integration into a system. In one embodiment, an error framework of a microprocessor or a hardware component includes an error detection unit to capture an error within the hardware component; a state detection unit to capture error context information when the error is detected within the hardware component; an error event definition unit to define a unique error event representing a combination of the error and the error context information; and a configuration unit to define an error event response based on the unique error event. The error context information may include, for example, a known state of a system at the time the error occurs or a known state of the hardware component or microprocessor within which the error is detected at the time the error occurs.

Error framework for a microprocesor and system

A method for detecting errors in a processing device is disclosed. A data source unit of a processing device transmits data and a qualifier synchronously with the data, the qualifier to indicate the data is uncorrectable. At least one intermediate functional unit in the processing device receives the data and the qualifier. The at least one intermediate functional unit detects the data is uncorrectable based on the qualifier. The at least one intermediate functional unit transmits, without using, the data and the qualifier synchronously with the data to a data consumer unit of the processing device. The data consumer unit receives the data and the qualifier. The data consumer unit detects the data is uncorrectable based on the qualifier. The data consumer unit maintains, without using the data and the qualifier.
