This + returns OPAL_SUCCESS for this case to avoid the error message. +- hw/phb3: fix error handling in complete reset + During a complete reset, when we get a timeout waiting for pending + transaction in state PHB3_STATE_CRESET_WAIT_CQ, we mark the PHB as broken + and return OPAL_PARAMETER. + Change the return code to OPAL_HARDWARE which is way more sensible, and set + the state to PHB3_STATE_FENCED so that the kernel can retry the complete + reset. |
