PCI Express System Architecture

Baseline Error Detection and Handling

This section defines the required support for detecting and reporting PCI Express errors. Each PCI Express compliant devices must include:

• PCI-Compatible support — required to support operating environments that have no knowledge of PCI Express.

• PCI Express Error reporting — available to operating environments that do have knowledge of PCI Express.

PCI-Compatible Error Reporting Mechanisms

Each PCI Express must map required PCI Express error support to the PCI-related error registers. This involves enabling error reporting and setting status bits that can be read by PCI-compliant software. To understand the features available from the PCI-compatible point of view consider the error-related bits of the Command ...
