This Chapter
To this point it has been presumed that transactions traversing the fabric have not encountered any errors that cannot be corrected by hardware. This chapter discusses both correctable and non-correctable errors and discusses the mechanisms used to report them. The PCI Express architecture provides a rich set of error detection, reporting, and logging capabilities. PCI Express error reporting classifies errors into three classes: correctable, non-fatal, and fatal. PCI Express error reporting capabilities include PCI-compatible mechanisms, thus a brief review of the PCI error handling is included as background information.
