A few new DSA operations are introduced [1]: 1. Memory fill with 16 bytes of pattern. 2. Translation fetch. 3. Data Integrity Extension (DIX) generate. This series adds descriptor definitions for the new DSA operations. With the definitions, user can issue the DSA operations to optimize corresponding transactions.
