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.

License

========

The Intel(R) Graphics Memory Management Library is distributed under the MIT

Open Source license.

You may obtain a copy of the License at:

https://opensource.org/licenses/MIT

Building

========

1) Get gmmlib repository

   

   git clone https://github.com/intel/gmmlib.git

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] ..``  

|        where,

|        -DCMAKE_BUILD_TYPE can be set to one build type flag at a time.

|        Example:

|        ``$ cmake -DCMAKE_BUILD_TYPE=Release ..``, For Release build

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

Supported Platforms

-------------------

Intel Atom and Core Processors supporting Gen8/Gen9/Gen10 graphics devices

BDW (Broadwell)

SKL (Skylake, Kaby Lake, Coffee Lake)

BXTx (BXT: Broxton, APL: Apollo Lake, GLK: Gemini Lake)

Release Tags

============

Gmmlib Release tag versioning schema follows:

| Tag ``intel-gmmlib-..`` 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-..`` becomes ``intel-gmmlib-.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
