Abstract: An embodiment includes a processor, included in a first die, detecting a first hardware error (e.g., memory corruption error). The processor formulates a first error message based on the detected first error. The processor may forward the first error message, via a first fabric included on the first die, to a first intellectual property (IP) agent or block, also included in the first die. This may be done using an in-band message, such as one that adheres to the integrated on-chip system fabric (IOSF) specification. The first IP agent may issue an error message that may, for example, alert a user to the error in a manner that is relatively close in time when the error first occurs. This may facilitate better error analysis. The first IP agent may include a processor (e.g., graphics processor), controller (e.g., power management controller), and the like. Other embodiments are described herein.
