4 Intel(R) QuickAssist (QAT) Compression Poll Mode Driver
5 =======================================================
7 The QAT compression PMD provides poll mode compression & decompression driver
8 support for the following hardware accelerator devices:
10 * ``Intel QuickAssist Technology C62x``
11 * ``Intel QuickAssist Technology C3xxx``
12 * ``Intel QuickAssist Technology DH895x``
18 QAT compression PMD has support for:
20 Compression/Decompression algorithm:
22 * DEFLATE - using Fixed and Dynamic Huffman encoding
30 * CRC32, Adler and combined checksum
35 * Compressdev level 0, no compression, is not supported.
36 * Queue pairs are not thread-safe (that is, within a single queue pair, RX and TX from different lcores is not supported).
37 * No BSD support as BSD QAT kernel driver not available.
43 The QAT compression PMD is built by default with a standard DPDK build.
45 It depends on a QAT kernel driver, see :ref:`building_qat`.
