Note: This README applies to QAT1.7, QAT1.8, and QAT2.0 devices. Not all sections may apply to your device generation. Previously existing build system has been replaced by Autotools solution in order to provide with the widely known and easy to use tool to build and install source packages. =============================================================================== Licensing ========== The Licensing of the files within this project splits under various set of licenses which are listed below. - Dual BSD/GPLv2 License - BSD License - GPLv2 License - OpenSSL License - ZLIB License For full GPLv2 License, please see the file LICENSE.GPL contained in the top level folder.

The mod_sign_cmd environment variable should be set to the path of the required kernel headers sign-file program and include it's first three command line arguments. e.g.: # export mod_sign_cmd='/scripts/sign-file sha256 /root/priv.key /root/pub.der' =============================================================================== 4) Configuration options These are common examples of the configure command: # ./configure ICP_ANY_FLAG=path or # ./configure --enable-something If it is required to use more than one flag at once: ./configure ICP_ANY_PATH=path ICP_ANY_NAME=name --enable-something Options are split into two following sections: Build flags: This set of flags has to be set (initial values are assigned by default) in order to process the proper QAT build. If a different setup if required - flags can be easily modified. Warning. Please keep in mind that any incorrect change might cause compilation problems - in such case default configuration setup is recommended to fix it. ICP_ROOT Path to the directory where acceleration software is extracted. (QAT package root directory) Type: path Default value: `pwd` ICP_BUILDSYSTEM_PATH Path to build system folder located under the quickassist directory. Type: path Default value: `pwd`/quickassist/build_system ICP_BUILD_OUTPUT Path to the output build directory where executables/libraries will be placed. Type: path Default value: `pwd`/build ICP_ENV_DIR Path to the directory containing the environment build files. Type: path Default value: pwd`/quickassist/build_system/build_files/ env_files ICP_TOOLS_TARGET Software platform target (Set ‘accelcomp’ for Intel® Communications Chipset Series Software platforms). Type: name Default value: accelcomp SYSROOT (QAT2.0 Hardware) Set the logical root directory for headers and libraries. This variable is used for cross-compilation. This variable is optional. Type: path Default value: none Features flags: Enables or disables the additional features supported by QAT package --disable-option-checking (QAT 1.7/1.8 Hardware) Ignores unrecognized configure options when run along with it. --enable-icp-debug Enables debugging. --enable-qat-uio (QAT2.0 Hardware) Enables Userspace I/O. --disable-param-check Disables parameters checking in the top-level APIs (Use for performance optimization). --disable-dc-dyn (QAT2.0 Hardware) Disables Dynamic compression support. --disable-stats Disables statistic collection (Use for performance optimization). --enable-drbg-poll-and-wait (QAT2.0 Hardware) Modifies the behavior of DRBG HT functions to use single threaded operation. --enable-icp-log-syslog Enables debugging messages to be outputted to the system log instead of standard output. --enable-icp-nonblocking-partials-perform Partial operations results are not being blocked. --enable-icp-sriov Enables Single-root I/O Virtualization in the QAT driver (available options: host, guest). Due to not common calling convention there is an example of invoke possibility: ./configure --enable-icp-sriov=host or ./configure --enable-icp-sriov=guest --enable-icp-trace Enables tracing for the Cryptography API. --enable-icp-asym-only (QAT2.0 Hardware) Enables driver to support asymmetric crypto services only. --enable-icp-sym-only (QAT2.0 Hardware) Enables driver to support symmetric crypto services only. --enable-icp-dc-only Enables driver supports only compression service (Can optimize size of build objects). --enable-icp-dc-sym-only Enables driver to support data compression and symmetric crypto services only. --enable-icp-dc-return-counters-on-error Enables updates of consumed/produced results in case of error during compression or decompression operations. --enable-icp-hb-fail-sim (QAT 1.7/1.8 Hardware) Enable Heartbeat Failure Simulation. --enable-qat-coexistence Enable driver co-existence with legacy 1.6 driver. --enable-qat-lkcf Enables QAT registration with Linux Kernel Crypto Framework --disable-dc-strict-mode (QAT 1.7/1.8 Hardware) Disables strict mode for data compression. --enable-dc-error-simulation (QAT 1.7/1.8 Hardware) Enables Data Compression Error Simulation. --enable-kapi (QAT 1.7/1.8 Hardware) Enables Intel(R) QuickAssist API in Kernel space. --enable-icp-without-thread (QAT 1.7/1.8 Hardware) Removes mutex and spin locks for single thread applications. --enable-legacy-algorithms (QAT 1.7+ only) Enable legacy algorithms. MAX_MR Number of Miller Rabin rounds for prime operations. Setting this to a smaller value reduces the memory usage required by the driver. Type: value Default value: 50 KERNEL_SOURCE_ROOT Path to kernel sources directory. Type: path Default value: /lib/modules/`uname –r`/build/ USE_HARD_CODED_PRIMES (QAT2.0 Hardware) Is auto enabled for C4XXX device to use pregenerated primes for sample code use Type: value Auto value: 1 for C4XXX device and 0 for all other devices =============================================================================== 5) Known Issues The current build system does not support dependency checking functionality which cause a call of clean during make. To avoid building the QAT package twice, first during "make" and second during "make install" call, it is recommended to call only the "make install", omitting "make": make install This same issue applies to "make samples" and "make samples-install".
