Checking the device driver status
The first step of troubleshooting while working with the EP11 enablement may be to check the device driver status as described in this topic.
Use the lszcrypt command like shown to retrieve basic status information. Type lszcrypt -V to achieve an output similar to the following:
# lszcrypt -V CARD.DOMAIN TYPE MODE STATUS REQUEST_CNT ... REQUESTQ_CNT HW_TYPE Q_DEPTH FUNCTIONS ------------------------------------------------------------------------------------------------ 02 CEX6A Accelerator online 6895 0 11 08 0x6a000000 02.004c CEX6A Accelerator online 6895 0 11 08 0x6a000000 03 CEX6C CCA-Coproc online 4627 0 11 08 0x92000000 03.004c CEX6C CCA-Coproc online 4627 0 11 08 0x92000000 05 CEX6P EP11-Coproc online 2284 0 11 08 0x06000000 05.004c CEX6P EP11-Coproc online 2284 0 11 08 0x06000000
This call can be used to check whether the EP11 requests are sent to a specific crypto adapter.
