Since SHA3 HW engine in ZynqMPSoC does not support parallel processing of 2 hash requests, so we have changed our approach. Now to support parallel processing of 2 hash requests, software fallback is being used for init, update, final, export and import in the ZynqMP SHA driver. For digest, the calculation of SHA3 hash is done by the hardened SHA3 accelerator in Xilinx ZynqMP SoC. Following tests have been done for the driver: - Enabled kernel self tests and extra run-time crypto self tests - Tested SHA hash computation for different sizes of data using userspace application - Tested SHA hash computation using multiple updates of data using userspace application - Tested parallel hash computation - Tested using the tcrypt module > > Regards Regards, Harsha
