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 8) reworks and refactors logic that is specific to the crypto service in order to be used by the compression service. In particular, the first 6 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 7 relocates the function qat_algs_alloc_flags() from a crypto specific header to qat_bl.h. Patch 8 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 9 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 10, extends the compression logic to support to QAT GEN4 devices. Patch 11 extends the acomp api by defining the max size for the destination buffer when a request is submitted with NULL destination buffer. This value is then used in the followin patch. Patch 12 implements the resubmission logic for decompression requests that is triggered if the destination buffer, allocated by the driver, is not sufficiently big to store the output from the operation. Changes from v1: - Implemented resubmission logic for decompression triggered when the output buffer allocated by the driver is not sufficiently large to store the result from the operation - Renamed buffer list functions that are moved to the qat_bl module Changes from v2: - Reworked decompression re-submission logic. For decompression operations submitted specifying NULL as destination buffer, resubmit once with a destination buffer of size 128KB instead of retying multiple times doubling every time the size of the destination buffer. - Added define in acomp api to specify the destination maximum size.
