This patch implements a special way of buffer handling when internal QAT IM buffer is too small for Huffman dynamic compression operation. Instead of falling back to fixed compression, the operation is now split into multiple smaller dynamic compression requests (possible to execute on QAT) and their results are then combined and copied into the output buffer. This is not possible if any checksum calculation was requested - in such case the code falls back to fixed compression as before.
v2: * various post-review small fixes v3: * refactor and simplify unit tests, removing the need of adding a new test suite separate for QAT-specific tests Adam Dybkowski (2): compress/qat: im buffer too small - split op test/compress: im buffer too small - add unit tests app/test/test_compressdev.c | 1185 ++++++++++++++++++++++-- doc/guides/compressdevs/qat_comp.rst | 3 - doc/guides/cryptodevs/qat.rst | 7 +- doc/guides/rel_notes/release_20_05.rst | 10 + drivers/common/qat/qat_qp.c | 223 ++++- drivers/common/qat/qat_qp.h | 3 + drivers/compress/qat/qat_comp.c | 474 +++++++++- drivers/compress/qat/qat_comp.h | 29 +- drivers/compress/qat/qat_comp_pmd.c | 27 +- 9 files changed, 1820 insertions(+), 141 deletions(-) -- 2.17.1
