# Intel(R) Graphics Compute Runtime for OpenCL(TM)
|
||||
|
||||
## Building
|
||||
|
||||
*Instructions assume clean Centos 7.4.1708 installation.**
|
||||
|
||||
1. Download & install required dependencies
|
||||
|
||||
Example:
|
||||
|
||||
```shell
|
||||
sudo yum groups install "Development Tools"
|
||||
sudo yum install centos-release-scl epel-release
|
||||
sudo yum install devtoolset-4-gcc-c++ llvm-toolset-7-clang cmake3 ninja-build p7zip rpm-build dpkg xorg-x11-util-macros libpciaccess-devel which zlib-devel
|
||||
sudo /usr/sbin/alternatives --install /usr/bin/cmake cmake /usr/bin/cmake3 50
|
||||
```
|
||||
|
||||
2. Create workspace folder and download sources:
|
||||
```
|
||||

||||
|
||||
Note: Instructions for compiling *Intel Graphics Compiler* copied from https://github.com/intel/intel-graphics-compiler/blob/master/README.md
|
||||
|
||||
3. Create folder for build:
|
||||
|
||||
Example:
|
||||
|
||||
```shell
|
||||

|
||||
```
|
||||
|
||||
4. Enabling additional extension

* [cl_intel_va_api_media_sharing](https://github.com/intel/compute-runtime/blob/master/documentation/cl_intel_va_api_media_sharing.md)
|
||||
|
||||
5. Build complete driver:
|
||||
|
||||
```shell
|
||||
cd build
|
||||
scl enable devtoolset-4 llvm-toolset-7 "cmake -DBUILD_TYPE=Release -DCMAKE_BUILD_TYPE=Release ../neo"
|
||||
scl enable devtoolset-4 llvm-toolset-7 "make -j `nproc` package"
|
||||
```
|
||||
|
||||
## Installing
|
||||
|
||||
To install OpenCL driver please use rpm package generated during build
|
||||
|
||||
Example:
|
||||
|
||||
```shell
|

sudo rpm -i intel-opencl-1.0-0.x86_64-igdrcl.rpm

# Intel(R) Graphics Compute Runtime for OpenCL(TM)
|
||||
|
||||
## Enabling [cl_intel_va_api_media_sharing](https://www.khronos.org/registry/OpenCL/extensions/intel/cl_intel_va_api_media_sharing.txt) extension
|
||||
|
||||
To enable cl_intel_va_api_media_sharing extension Neo needs to be compiled on system with libva 2.x installed.
|
||||
Before compilation additional packages have to be installed.
|
||||
|
||||
1. Download sources:
|
||||
|
||||
* libdrm https://anongit.freedesktop.org/git/mesa/drm.git
|
||||
* libva https://github.com/intel/libva.git
|
||||
|
||||
Example:
|
||||
|
||||
```shell
|
||||
git clone https://anongit.freedesktop.org/git/mesa/drm.git libdrm
|
||||
git clone https://github.com/intel/libva.git libva
|
||||
|
||||
2. Compile and install libdrm
|
||||
|
||||
Example:
|
||||
|
||||
```shell
|
||||
cd libdrm
|
||||
./autogen.sh
|
||||
make -j `nproc`
|
||||
sudo make install
|
||||
```
|
||||
|
||||
3. Compile and install libva
|
||||
|
||||
Example:
|
||||
|
||||
```shell
|
||||
cd libva
|
||||
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
|
||||
./autogen.sh
|
||||
make -j `nproc`
|
||||
sudo make install
|
||||
```
|
||||
|
||||
4. During Neo compilation verify libva was discovered
|
||||
|
||||
```shell
|
||||
-- Checking for module 'libva>=1.0.0'
|
||||
-- Found libva, version 1.1.0
|
||||
-- Looking for vaGetLibFunc in va
|
||||
-- Looking for vaGetLibFunc in va - found
|
||||
-- Using libva
|
||||
```
