The AER error information printing support is implemented in drivers/pci/pcie/aer/aer_print.c. So some string constants, functions and macros definitions can be re-used without being exported. The original PCIe AER error information printing function is not re-used directly because the overall format is quite different. And changing the original printing format may make some original users' scripts broken.

APEI output format

APEI uses printk as hardware error reporting interface, the output
|
|
format is as follow.
