This is not possible if any checksum calculation\nwas requested - in such case the code falls back to fixed compression\nas before.\n\nv2:\n* various post-review small fixes\nv3:\n* refactor and simplify unit tests, removing the need of\nadding a new test suite separate for QAT-specific tests\n\nAdam Dybkowski (2):\n compress/qat: im buffer too small - split op\n test/compress: im buffer too small - add unit tests\n\n app/test/test_compressdev.c | 1185 ++++++++++++++++++++++--\n doc/guides/compressdevs/qat_comp.rst | 3 -\n doc/guides/cryptodevs/qat.rst | 7 +-\n doc/guides/rel_notes/release_20_05.rst | 10 +\n drivers/common/qat/qat_qp.c | 223 ++++-\n drivers/common/qat/qat_qp.h | 3 +\n drivers/compress/qat/qat_comp.c | 474 +++++++++-\n drivers/compress/qat/qat_comp.h | 29 +-\n drivers/compress/qat/qat_comp_pmd.c | 27 +-\n 9 files changed, 1820 insertions(+), 141 deletions(-)" }
