This patch is required not to lost error records by action invoked on error recovery, such as slot reset etc. Following sample (real machine + dummy record injected by aer-inject) shows that record of 28:00.1 could not be retrieved by recovery of 28:00.0: - Before: pcieport-driver 0000:00:02.0: AER: Multiple Uncorrected (Non-Fatal) error received: id=2801 e1000e 0000:28:00.0: PCIE Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, id=2800(Receiver ID) e1000e 0000:28:00.0: device [8086:1096] error status/mask=00001000/00100000 e1000e 0000:28:00.0: [12] Poisoned TLP (First) e1000e 0000:28:00.0: TLP Header: 00000000 00000001 00000002 00000003 e1000e 0000:28:00.0: broadcast error_detected message e1000e 0000:28:00.0: broadcast slot_reset message e1000e 0000:28:00.0: setting latency timer to 64 e1000e 0000:28:00.0: restoring config space at offset 0x1 (was 0x100547, writing 0x100147) e1000e 0000:28:00.0: PME# disabled e1000e 0000:28:00.0: PME# disabled e1000e 0000:28:00.1: setting latency timer to 64 e1000e 0000:28:00.1: restoring config space at offset 0x1 (was 0x100547, writing 0x100147) e1000e 0000:28:00.1: PME# disabled e1000e 0000:28:00.1: PME# disabled e1000e 0000:28:00.0: broadcast resume message e1000e 0000:28:00.0: AER driver successfully recovered e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX - After: pcieport-driver 0000:00:02.0: AER: Multiple Uncorrected (Non-Fatal) error received: id=2801 e1000e 0000:28:00.0: PCIE Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, id=2800(Receiver ID) e1000e 0000:28:00.0: device [8086:1096] error status/mask=00001000/00100000 e1000e 0000:28:00.0: [12] Poisoned TLP (First) e1000e 0000:28:00.0: TLP Header: 00000000 00000001 00000002 00000003 e1000e 0000:28:00.1: PCIE Bus Error: severity=Uncorrected (Non-Fatal), type=Transaction Layer, id=2801(Receiver ID) e1000e 0000:28:00.1: device [8086:1096] error status/mask=00081000/00100000 e1000e 0000:28:00.1: [12] Poisoned TLP (First) e1000e 0000:28:00.1: [19] ECRC e1000e 0000:28:00.1: TLP Header: 00000000 00000001 00000002 00000003 e1000e 0000:28:00.1: Error of this Agent(2801) is reported first e1000e 0000:28:00.0: broadcast error_detected message e1000e 0000:28:00.0: broadcast slot_reset message e1000e 0000:28:00.0: setting latency timer to 64 e1000e 0000:28:00.0: restoring config space at offset 0x1 (was 0x100547, writing 0x100147) e1000e 0000:28:00.0: PME# disabled e1000e 0000:28:00.0: PME# disabled e1000e 0000:28:00.1: setting latency timer to 64 e1000e 0000:28:00.1: restoring config space at offset 0x1 (was 0x100547, writing 0x100147) e1000e 0000:28:00.1: PME# disabled e1000e 0000:28:00.1: PME# disabled e1000e 0000:28:00.0: broadcast resume message e1000e 0000:28:00.0: AER driver successfully recovered e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
