Reg. #308263 - Collinstown Industrial Park, Leixlip, County Kildare - Ireland Precedence: bulk List-ID: X-Mailing-List: linux-crypto@vger.kernel.org This set enables the offload of the compression deflate algorithm to QAT accelerators through the acomp API. The first part of the set (patches 1 to 7) reworks and refactors logic that is specific to the crypto service in order to be used by the compression service. In particular, the first 5 patches rework the buffer list logic, which is used to map, unmap and convert scatterlists into the format that the QAT firmware can understand. These relocate the bufferlist logic to a separate file, change the interfaces so that the logic is service agnostic (not tied to compression or crypto) and extend the interface to allow an additional pre-allocated buffer for each destination scatter list which will be used to avoid premature overflows reported by the compression hardware. Patch 6 relocates the function qat_algs_alloc_flags() from a crypto specific header to qat_bl.h. Patch 7 moves and renames the configuration function for GEN2, qat_crypto_dev_config(), to a new file, adf_gen2_config.h, which contains the configuration logic for both crypto and compression instances for QAT GEN2 devices. The last 2 patches in the set introduce all the infrastructure required to enable the compression service in the QAT driver and expose it through the acomp APIs. In particular, patch 8 introduces the logic related to the creation and handling of compression instances and their configuration. In addition, it adds the back-end for qat_deflate to plug into acomp, including the logic to build descriptors for the newly added GEN2 compression firmware APIs. This was all kept in a single patch to avoid introducing unused logic in the QAT driver in previous patches. Patch 9, extends the compression logic to support to QAT GEN4 devices. All new files in this set are marked as dual license. This is since portions of the QAT code are shared with QAT projects which are released under compatible licenses. Occasionally changes are brought back to the shared codebase used by those projects.
