Subject: [PATCH v4 1/8] PCI/AER: Remove ID from aer_agent_string[]
Date: Tue,  5 Oct 2021 22:48:08 +0530	[thread overview]
Message-ID: <22b2dae2a6ac340d9d45c28481d746ec1064cd6c.1633453452.git.naveennaidu479@gmail.com> (raw)
In-Reply-To: <cover.1633453452.git.naveennaidu479@gmail.com>

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[].

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
