The series of patches supports PCI error injection as defined in PAPR spec. There are 3 RTAS calls related to it: "ibm,open-errinjct": Apply for token to do error injection "ibm,close-errinjct": Free the token assigned previously "ibm,errinjct": Do error injection For PCI errors, we need manupulate 3 hardware registers by predetermined OPAL API. In order to export the capability to userland, one OPAL firmware related sysfs entries are created: /sys/firmware/opal/errinjct. It accepts strings to call OPAL API to inject specific errors. So it corresponds to "ibm,errinjct". So "ibm,open-errinjct" and "ibm,close-errinjct" won't be handled by host kernel and applications have full freedom to implement logic of themselves for them.
