This to reflect current name for basic sample, zello_world_gpu. Also, modify this sample to return vendorId in hexadecimal format. Change-Id: If073648e436b607125a9f4176db640d070f7f7f3 Signed-off-by: Jaime Arteaga <jaime.a.arteaga.molina@intel.com>

# Building Level Zero
|
|
|
|
These instructions have been tested on Ubuntu* and complement those existing for NEO in the top-level BUILD.md file.
|
|
|
|
1. Install/build Level Zero loader and Level Zero headers
|
|
|
|
Install Level Zero loader and headers from [https://github.com/oneapi-src/level-zero/releases](https://github.com/oneapi-src/level-zero/releases).
|
|
|
|
For execution, only the level-zero package is needed; for compilation, level-zero-devel package is also required.
|
|
|
|
Alternatively, build Level Zero loader from source, as indicated in [https://github.com/oneapi-src/level-zero](https://github.com/oneapi-src/level-zero).
|
|
|
|
Build will generate ze_loader library and symlinks, as well as those for ze_validation_layer.
|
|
|
|
2. Install/build Level Zero driver
|
|
|
|
Install Level Zero package from [https://github.com/intel/compute-runtime/releases](https://github.com/intel/compute-runtime/releases).
|
|
|
|
Alternatively, follow instructions in top-level BUILD.md file to build NEO. Level Zero is built by default.
|
|
|
|
When built, ze_intel_gpu library and symlinks are generated.
|
|
|
|
3. Build your application
|
|
|
|
Compilation needs to include the Level Zero headers and to link against the loader library:
|
|
|
|
```shell
|
|
g++ zello_world_gpu.cpp -o zello_world_gpu -lze_loader
|
|
```
|
|
|
|
If libraries not installed in system paths, include Level Zero headers and path to Level Zero loader:
|
|
|
|
```shell
|
|
g++ -I<path_to_Level_Zero_headers> zello_world_gpu.cpp -o zello_world_gpu -L<path_to_libze_loader.so> -lze_loader
|
|
```
|
|
|
|
4. Execute your application
|
|
|
|
If Level Zero loader packages have been built and installed in the system, then they will be present in system paths:
|
|
|
|
```shell
|
|
./zello_world_gpu
|
|
```
|
|
|
|
Sample output:
|
|
|
|
```shell
|
|
Device :
|
|
* name : Intel(R) Graphics Gen9 [0x5912]
|
|
* type : GPU
|
|
* vendorId : 8086
|
|
|
|
Zello World Results validation PASSED
|
|
```
|
|
|
|
If libraries not installed in system paths, add paths to ze_loader and ze_intel_gpu libraries:
|
|
|
|
```shell
|
|
LD_LIBRARY_PATH=<path_to_libze_loader.so>:<path_to_libze_intel_gpu.so> ./zello_world_gpu
|
|
```
