/linux/Documentation/PCI/
A Dpcieaer-howto.rst105 PCI Express errors are classified into two types: correctable errors
110 Correctable errors pose no impacts on the functionality of the
112 intervention or any loss of data. These errors are detected and
113 corrected by hardware. Unlike correctable errors, uncorrectable
114 errors impact functionality of the interface. Uncorrectable errors
117 errors are further classified into non-fatal errors and fatal errors.
135 errors because device specific errors will still get sent directly to
