There are both software libraries and hardware devices available that provide compression, but no common API. Such an API is proposed in this patchset, which supports the following features: - Deflate Algorithm (https://tools.ietf.org/html/rfc1951) - LZS algorithm (https://tools.ietf.org/html/rfc2395) - Static and Dynamic Huffman encoding. - Compression levels - Checksum generation - Asynchronous burst API - private_xform - a place for PMDs to hold private data derived from a xform and used by stateless operations. - stream - a place for PMDs to hold private data derived from a xform and also maintain state and history data. For stateful flows. Signed-off-by: Fiona Trahe Signed-off-by: Pablo de Lara pablo.de.lara.guarch@intel.com Signed-off-by: Shally Verma Signed-off-by: Ashish Gupta Changes in v5: - Make rte_compressdev_is_valid_dev, rte_compressdev_pmd_get_dev functions internal - Add rte_comp.h to API doc - Remove unused rte_comp_op_get_user_data, rte_comp_op_get_user_data_size functions - Fix comment - Move private data size arg out of PMD init params structure - Split out of space error status into two - Make rte_comp_op_alloc, rte_comp_op_bulk_alloc, rte_comp_free, rte_compressdev_enqueue_burst and rte_compressdev_dequeue_burst functions not inline. - Move rte_compressdev and rte_compressdev_data structures out of rte_compressdev.h, making them internal to the API - Remove unneeded driver registration (used in cryptodev, for multi PMD sessions) - Remove unneeded includes - rte_comp_op_bulk_alloc returns now 0 on success, instead of the number of allocated operations - Move internals macros to rte_compressdev_internals.h, to avoid exposing them unnecessarily Changes in v4: - Fix build (missing ";") - Change order in common_base, so compression is placed after security Changes in v3: - Remove rte_comp_op_ctod helper functions - Remove param_range_check macro - Rename from phys_addr to iova_addr - Remove rte_comp_algo_strings - Rename rte_compressdev_pmd_is_valid_dev to rte_compressdev_is_valid_dev - Remove feature flags from compressdev - Support hash operations - Add shareable priv xform in feature flags, instead of returnin it on xform creation - Allow max number of queue pairs to be 0, meaning that there is no limit. - Add invalid configuration checks - Add capability helper functions Changes in v2: - Add stream APIs - Remove session - Add SHAREABLE / NON_SHAREABLE private_xform types - Add algo enum 'UNSPECIFIED' to fix warning in capabilities - Change one remaining log to use dynamic logging. - Add rte_cache_aligned keyword to op - Rename enums with better names _ALGO, __CHECKSUM, _HUFFMAN_ - Use const keyword when passing xform - Remove qp_count fn from dev_ops as never used - Remove max_nb_queue-pairs from compressdev_init_param as never used - Clarify device configure and start sequence - Replace OUT_OF_SPACE with OUT_OF_SPACE_RECOVERABLE and TERMINATED and clarified usage. - Add stream and private_xform sizes to device config for use in mempool creation - Add capability helper fn - Use Base2 log value for window size on xforms - Add Meson build - Update MAINTAINERS - Update Map file - Change order in doxy file - Update Release note Fiona Trahe (12): compressdev: add basic device management compressdev: add queue pair management compressdev: add compression specific data compressdev: add enqueue/dequeue functions compressdev: add operation management compressdev: support stateless operations compressdev: support stateful operations compressdev: add device feature flags compressdev: add compression service feature flags compressdev: add device stats compressdev: add device capabilities compressdev: get device id from name Shally Verma (1): compressdev: support hash operations MAINTAINERS | 7 + config/common_base | 6 + config/rte_config.h | 3 + doc/api/doxy-api-index.md | 2 + doc/api/doxy-api.conf | 1 + doc/guides/rel_notes/release_18_05.rst | 6 + lib/Makefile | 3 + lib/librte_compressdev/Makefile | 31 + lib/librte_compressdev/meson.build | 12 + lib/librte_compressdev/rte_comp.c | 207 ++++++ lib/librte_compressdev/rte_comp.h | 464 +++++++++++++ lib/librte_compressdev/rte_compressdev.c | 734 +++++++++++++++++++++ lib/librte_compressdev/rte_compressdev.h | 536 +++++++++++++++ lib/librte_compressdev/rte_compressdev_internal.h | 123 ++++ lib/librte_compressdev/rte_compressdev_pmd.c | 160 +++++ lib/librte_compressdev/rte_compressdev_pmd.h | 390 +++++++++++ lib/librte_compressdev/rte_compressdev_version.map | 42 ++ lib/meson.build | 2 +- mk/rte.app.mk | 1 + 19 files changed, 2729 insertions(+), 1 deletion(-) create mode 100644 lib/librte_compressdev/Makefile create mode 100644 lib/librte_compressdev/meson.build create mode 100644 lib/librte_compressdev/rte_comp.c create mode 100644 lib/librte_compressdev/rte_comp.h create mode 100644 lib/librte_compressdev/rte_compressdev.c create mode 100644 lib/librte_compressdev/rte_compressdev.h create mode 100644 lib/librte_compressdev/rte_compressdev_internal.h create mode 100644 lib/librte_compressdev/rte_compressdev_pmd.c create mode 100644 lib/librte_compressdev/rte_compressdev_pmd.h create mode 100644 lib/librte_compressdev/rte_compressdev_version.map -- 2.14.3
