12 * PCIe AER Trace event
13 *
14 * These events are generated when hardware detects a corrected or
15 * uncorrected event on a PCIe device. The event report has
16 * the following structure:
17 *
18 * char * dev_name - The name of the slot where the device resides
19 * ([domain:]bus:device.function).
20 * u32 status - Either the correctable or uncorrectable register
21 * indicating what error or errors have been seen
22 * u8 severity - error severity 0:NONFATAL 1:FATAL 2:CORRECTED
