| ******************************************* |
| |
| Introduction |
| ============= |
| |
| The Intel(R) Graphics Memory Management Library provides device specific and buffer |
| management for the Intel(R) Graphics Compute Runtime for OpenCL(TM) and the |
| Intel(R) Media Driver for VAAPI. |
| |

| Building |
| ======== |
| 1) Get gmmlib repository |
| |
| 2) Change it to root directory |
| |
| ``$ cd gmmlib`` |
| |
| 3) Make a build directory |
| |
| ``$ mkdir build && cd build`` |
| |
| 4) Run the cmake command to prepare build files |
| |
| ``$ cmake [-DCMAKE_BUILD_TYPE= Release | Debug | ReleaseInternal] [-DARCH= 64 | 32] ..`` |
| |
| 5) Build the project |
| |
| ``$ make -j"$(nproc)" (Also performs compile time ULT)`` |
| |
| Install |
| ======= |
| ``$ sudo make install`` |
| |
| This will install the following files (e.g. on Ubuntu): |
| |
| | -- Install configuration: "Release" |
| | -- Installing: /usr/local/lib/libigdgmm.so.12.1.0 |
| | -- Installing: /usr/local/lib/libigdgmm.so.12 |
| | |
| |
| |
| Not a stand alone software component. |
| GmmLib is built as dynamic library for Intel media driver and Compute runtime for OpenCL |
| |

| |
| Release Tags |
| ============ |
| |
| Gmmlib Release tag versioning schema follows: |
| |
| | Tag ``intel-gmmlib-<x>.<y>.<z>`` will be stable release series with the same API and ABI version with only bug fixes where, |
| | x = GMMLIB_API_MAJOR_VERSION + 10, |
| | y = GMMLIB_API_MINOR_VERSION, |
| | z = RELEASE NUMBER which is incremented as 0,1,2,...n for changes including new flag, bug fixes, etc. |
| | |
| | Example: |
| | For GMM library ``libigdgmm.so.12.0.0``, |
| | Tag = ``intel-gmmlib-22.0.0`` where, |
| | 22 = GMMLIB_API_MAJOR_VERSION + 10 = 12 + 10 |
| | 0 = GMMLIB_API_MINOR_VERSION |
| | 0 = RELEASE NUMBER |
| | |
| On potential ABI break changes, |
| |
| | Tag ``intel-gmmlib-<x>.<y>.<z>`` becomes ``intel-gmmlib-<x + 1>.0.0`` |
| | i.e ``intel-gmmlib-22.5.3`` becomes ``intel-gmmlib-23.0.0`` |
| |
| Known Issues and Limitations |
| ============================ |
| Current Gmmlib support only limited to Linux |
