Subject: [PATCH v7 4/5] PCI/AER: Clear both AER fatal and non-fatal status
Date: Sat, 24 Jan 2026 15:45:56 +0800 [thread overview]
Message-ID: <20260124074557.73961-5-xueshuai@linux.alibaba.com> (raw)
In-Reply-To: <20260124074557.73961-1-xueshuai@linux.alibaba.com>
The DPC driver clears AER fatal status for the port that reported the
error, but not for the downstream device that deteced the error. The
current recovery code only clears non-fatal AER status, leaving fatal
status bits set in the error device.
Use pci_aer_raw_clear_status() to clear both fatal and non-fatal error
status in the error device, ensuring all AER status bits are properly
cleared after recovery.
Fixes: aa344bc8b727 ("PCI/ERR: Clear AER status only when we control AER")
