### Llama.cpp + OpenCL
The llama.cpp OpenCL backend is designed to enable llama.cpp on **Qualcomm Adreno GPU** firstly via OpenCL. Thanks to the portabilty of OpenCL, the OpenCL backend can also run on certain Intel GPUs such as those that do not have [SYCL](/docs/backend/SYCL.md) support although the performance is not optimal.

## Linux
The two steps just above also apply to Linux. When building for linux, the commands are mostly the same as those for PowerShell on Windows, but in the second step they do not have the `-DCMAKE_TOOLCHAIN_FILE` parameter, and then in both steps the backticks are replaced with back slashes.
If not installed already, install Git, CMake, Clang, Ninja and Python, then run in the terminal the following:
### I. Setup Environment
1. **Install OpenCL Headers and Library**
```bash
mkdir -p ~/dev/llm
cd ~/dev/llm
git clone https://github.com/KhronosGroup/OpenCL-Headers && cd OpenCL-Headers
mkdir build && cd build
cmake .. -G Ninja \
-DBUILD_TESTING=OFF \
-DOPENCL_HEADERS_BUILD_TESTING=OFF \
-DOPENCL_HEADERS_BUILD_CXX_TESTS=OFF \
-DCMAKE_INSTALL_PREFIX="$HOME/dev/llm/opencl"
cmake --build . --target install
cd ~/dev/llm
git clone https://github.com/KhronosGroup/OpenCL-ICD-Loader && cd OpenCL-ICD-Loader
mkdir build && cd build
cmake .. -G Ninja \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_PREFIX_PATH="$HOME/dev/llm/opencl" \
-DCMAKE_INSTALL_PREFIX="$HOME/dev/llm/opencl"
cmake --build . --target install
```
### II. Build llama.cpp
```bash
mkdir -p ~/dev/llm
cd ~/dev/llm
git clone https://github.com/ggml-org/llama.cpp && cd llama.cpp
mkdir build && cd build
cmake .. -G Ninja \
-DCMAKE_BUILD_TYPE=Release \
