Features
--------
+ZSDA compression PMD has support for:
+
+Compression/Decompression algorithm:
+
+ * DEFLATE - using Fixed and Dynamic Huffman encoding
+
+Checksum generation:
+
+ * CRC32, Adler32
+
+Huffman code type:
+
+* FIXED
+* DYNAMIC
+
+
+Limitations
+-----------
+
+* Compressdev level 0, no compression, is not supported.
+* No BSD support as BSD ZSDA kernel driver not available.
+* Stateful is not supported.

New Features
------------
+* **Added ZTE Storage Data Accelerator(ZSDA) device driver.**
+
+ * Added a new compress driver for ZSDA devices to support
+ the deflate compression and decompression algorithm.
+
+ See the :doc:`../compressdevs/zsda` guide for more details on the new driver.
