PCI AER: software error injection

Browse source 
Debugging PCIE AER code can be very difficult because it is hard
to trigger various real hardware errors. This patch provide a
software based error injection tool, which can fake various PCIE
errors with a user space helper tool named "aer-inject". Which
can be gotten from:

The patch fakes AER error by faking some PCIE AER related
registers and an AER interrupt for specified the PCIE device.
