Abstract
Embodiments of the invention relate to scalable input/output (I/O) function level error detection, isolation, and reporting. An aspect of the invention includes detecting an error in a communication initiated between the function and a system memory, the communication including an I/O request from an application. Future communication is prevented between the one function and the system memory in response to the detecting. The application is notified that the error in communication occurred in response to the detecting.
Claims7
A computer implemented method for implementing scalable input/output (I/O) function level error detection, isolation, and reporting, the method comprising:
- detecting, via an I/O hub, an error in a communication initiated between a function and a system memory, the communication including an I/O request from an application, and the function executing on an I/O adapter;
- preventing future communication between the function and the system memory in response to the detecting;
- and
- notifying the application that the error in communication occurred in response to the detecting.
