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 Signed-off-by: Naveen Naidu --- drivers/pci/pcie/aer.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/pci/pcie/aer.c b/drivers/pci/pcie/aer.c index 9784fdcf3006..241ff361b43c 100644 --- a/drivers/pci/pcie/aer.c +++ b/drivers/pci/pcie/aer.c @@ -516,10 +516,10 @@ static const char *aer_uncorrectable_error_string[] = { }; static const char *aer_agent_string[] = { - "Receiver ID", - "Requester ID", - "Completer ID", - "Transmitter ID" + "Receiver", + "Requester", + "Completer", + "Transmitter" }; #define aer_stats_dev_attr(name, stats_array, strings_array, \ @@ -703,7 +703,7 @@ void aer_print_error(struct pci_dev *dev, struct aer_err_info *info) const char *level; if (!info->status) { - pci_err(dev, "PCIe Bus Error: severity=%s, type=Inaccessible, (Unregistered Agent ID)\n", + pci_err(dev, "PCIe Bus Error: severity=%s, type=Inaccessible, (Unregistered Agent)\n", aer_error_severity_string[info->severity]); goto out; }
