Intel(R) Graphics Memory Management Library

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

Get gmmlib repository
Change it to root directory

$ cd gmmlib
Make a build directory

$ mkdir build && cd build
Run the cmake command to prepare build files

$ cmake [-DCMAKE_BUILD_TYPE= Release | Debug | ReleaseInternal] [-DARCH= 64 | 32] ..
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
