As I understand, there is a error_handle in the PCI device driver that gets called when an error is received by the AER driver so that device can handle it. At this point, I am trying to test the AER driver with any error that can be injected to check if the error handle is being called. I will dig more into the inject feature to get an answer, but if you know this is possible or not, please reply. Thanks.
