2015-06-25s390/zcrypt: Fixed reset and interrupt handling of AP queuesIngo Tuchscherer1-1/+1
In case of request timeouts an AP queue reset will be triggered to recover and reinitialize the AP queue. The previous behavior was an immediate reset execution regardless of current/pending requests. Due to newly changed firmware behavior the reset may be delayed, based on the priority of pending request. The device driver's waiting time frame was limited, hence it did not received the reset response. As a consequence interrupts would not be enabled afterwards. The RAPQ (queue reset) and AQIC (interrupt control) commands will be treated fully asynchronous now. The device driver will check the reset and interrupt states periodically, thus it can handle the reinitialization properly.
