Subject: [PATCH v2 1/8] PCI/AER: Remove ID from aer_agent_string[]
Date: Mon,  4 Oct 2021 19:36:27 +0530	[thread overview]
Message-ID: <b4c5a5005d4549420cf6e86f31a01d3fb2876731.1633353468.git.naveennaidu479@gmail.com> (raw)
Message-ID: <20211004140627.L9Ory2bL_N9H4mTmqby8I92QVcOUJ36Ob2XJgdEMLVs@z> (raw)
In-Reply-To: <cover.1633353468.git.naveennaidu479@gmail.com>

Before 010caed4ccb6 ("PCI/AER: Decode Error Source RequesterID")
the AER error logs looked like:

  pcieport 0000:00:03.0: AER: Corrected error received: id=0018
  pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=0018 (Receiver ID)
  pcieport 0000:00:03.0:   device [1b36:000c] error status/mask=00000040/0000e000
  pcieport 0000:00:03.0:    [ 6] BadTLP

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)
  pcieport 0000:00:03.0:   device [1b36:000c] error status/mask=00000040/0000e000
  pcieport 0000:00:03.0:    [ 6] BadTLP

The second line in the above logs prints "(Receiver ID)", even when
there is no "id" in the log line. This is confusing.

Remove the "ID" from the aer_agent_string[]. The error logs will
look as follows (Sample from dummy error injected by aer-inject):

  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
