PCIe Device AER statistics
|
|
==========================
|
|
These attributes show up under all the devices that are AER capable. These
|
|
statistical counters indicate the errors "as seen/reported by the device".
|
|
Note that this may mean that if an endpoint is causing problems, the AER
|
|
counters may increment at its link partner (e.g. root port) because the
|
|
errors may be "seen" / reported by the link partner and not the
|
|
problematic endpoint itself (which may report all counters as 0 as it never
|
|
saw any problems).

PCIe Rootport AER statistics
|
|
============================
|
|
These attributes show up under only the rootports (or root complex event
|
|
collectors) that are AER capable. These indicate the number of error messages as
|
|
"reported to" the rootport. Please note that the rootports also transmit
|
|
(internally) the ERR_* messages for errors seen by the internal rootport PCI
|
|
device, so these counters include them and are thus cumulative of all the error
|
|
messages on the PCI hierarchy originating at that root port.
