Problem summary

  • xcrypto cards will reset and and the next error log will be
    printed:
    
    XCRYPT_DMABUS_ERROR Detail Data FILE NAME line: 196 file:
    xcrypt_intr.c EVENT DATA:  00 EVENT DATA:  0000 8000 EVENT
    DATA:  4000 FF01    <===== The 4000 in the extra data is called
    an split complete error.
    
    Problem occurs due to a synchronization issue in the xcrypto
    device driver.
    

Problem conclusion

  • To add a sync in the functon to tsend the HRB to the cards.
    In systems where out of order instructions can happen,
    can force the code to set a flag indicating that
    the buffer is ready for the card to process before
    we have finished the completion of the buffer.
    The sync will keep the order of completing the
    buffer before the flag is set.
