12 Reporting (AER) driver and provides information on how to use it, as
14 PCI Express AER driver.
18 1.3 What is the PCI Express AER Driver?
29 The PCI Express AER driver provides the infrastructure to support PCI
30 Express Advanced Error Reporting capability. The PCI Express AER
37 AER driver only attaches root ports which support PCI-Express AER
43 2.1 Include the PCI Express AER Root Driver into the Linux Kernel
45 The PCI Express AER Root driver is a Root Port service driver attached
51 2.2 Load PCI Express AER Root Driver
53 Some systems have AER support in firmware. Enabling Linux AER support at
54 the same time the firmware handles AER may result in unpredictable
55 behavior. Therefore, Linux does not handle AER events unless the firmware
56 grants AER control to the OS via the ACPI _OSC method. See the PCI FW 3.0
59 2.3 AER error output
61 When a PCIe AER error is captured, an error message will be output to
76 2.4 AER Statistics / Counters
78 When PCIe AER errors are captured, the counters / statistics are also exposed
84 To enable AER aware support requires a software driver to configure
85 the AER capability structure within its device and to provide callbacks.
87 To support AER better, developers need understand how AER does work
107 When AER is enabled, a PCI Express device will automatically send an
114 Status Register accordingly. If AER error reporting is enabled in Root
123 3.1 Configure the AER capability structure
125 AER aware drivers of PCI Express component need change the device
126 control registers to enable AER. They also could change AER registers,
128 pci_enable_pcie_error_reporting could be used to enable AER. See
151 The PCI Express AER Root driver uses error callbacks to coordinate
157 pointers. AER driver follows the rules defined in
169 require any recovery actions. The AER driver clears the device's
175 at upstream is not required. The AER driver calls error_detected(dev,
179 If Upstream port A captures an AER error, the hierarchy consists of
184 whether it can recover or the AER driver calls mmio_enabled as next.
190 to reset link, AER port service driver is required to provide the
242 with the PCI Express AER Root driver?
244 A: It could call the helper functions to enable AER in devices and
250 Debugging PCIe AER error recovery code is quite difficult because it
254 First you should enable PCIe AER software error injection in kernel
