This patch series add software zlib library (http://zlib.net/) based compression PMD in DPDK compress drivers.
Application must need to install zlib prior to enabling this PMD to avail compression/decompression services. Currently driver only tested for deflate, stateless compression and decompression. Changes in v4: - fixed -Wimplcit-fallthrough compilation error with gcc-7+ toolchain Changes in v3: - added comp_feature_flags to compressdev_capabilities - removed stream_create as stateful not supported - changed compression strategy to DEFAULT_STRATEGY - Simplified core processing logic - fix doc build error - other v2 feedbacks TBDs - No change to current qp enqueue_err stats update. - PMD increment enqd_err stats, if it fails to push op into completion queue. This logic to be revisited based on further discussion Changes in v2: - removed unused variables - corrected capability to reflect current support - add lookup for internally maintained mempool during device_configure - optimized core compression/decompression logic in enq/deq APIs - updated documentation with correct feature support v1 includes: - build changes to build zlib PMD - zlib PMD implementation - zlib PMD documentation - meson build support This patchset is dependent upon compressdev API.
