| |
Currently, we do not print the "id" field in the AER error logs. Yet the aer_agent_string[] has the word "id" in it. The AER error log looks like:
pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID)
Without the "id" field in the error log, The aer_agent_string[] (eg: "Receiver ID") does not make sense. A user reading the aer_agent_string[] in the log, might inadvertently look for an "id" field and not finding it might lead to confusion.
Remove the "ID" from the aer_agent_string[].
It is easy to reproduce this by using aer-inject:
$ aer-inject -s 00:03:0 corr-err-file
The content of the corr-err-file file is as below:
AER COR_STATUS BAD_TLP HEADER_LOG 0 1 2 3
The following are sample dummy errors inject via aer-inject.
Before =======
In 010caed4ccb6 ("PCI/AER: Decode Error Source Requester ID"), the "id" field was removed from the AER error logs, so currently AER logs look like:
pcieport 0000:00:03.0: AER: Corrected error received: 0000:00:03:0 pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver ID) <--- no id field pcieport 0000:00:03.0: device [1b36:000c] error status/mask=00000040/0000e000 pcieport 0000:00:03.0: [ 6] BadTLP
After ======
pcieport 0000:00:03.0: AER: Corrected error received: 0000:00:03.0 pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Receiver) pcieport 0000:00:03.0: device [1b36:000c] error status/mask=00000040/0000e000 pcieport 0000:00:03.0: [ 6] BadTLP
