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
========

1) Get gmmlib repo

       |- gmmlib

2) Change it to root directory

   $ cd gmmlib

3) $ mkdir build && cd build

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

5) $ make -j8 ( Also performs compile time ULT)

 
Install
^^^^^^^
Not a stand alone software component.
GmmLib is built as dynamic library for Intel media driver and Compute runtime for OpenCL
