# # PCI Express Root Port Device AER Debug Configuration # config PCIEAER_INJECT tristate "PCIe AER error injector support" depends on PCIEAER default n help This enables PCI Express Root Port Advanced Error Reporting (AER) software error injector. Debugging PCIe AER code is quite difficult because it is hard to trigger various real hardware errors. Software based error injection can fake almost all kinds of errors with the help of a user space helper tool aer-inject, which can be gotten from: http://www.kernel.org/pub/linux/utils/pci/aer-inject/
