##### Installing RKNN LLM and RKNN Toolkit 2

Réf. : [https://github.com/Pelochus/ezrknpu](https://github.com/Pelochus/ezrknpu)

```bash
sudo apt install cmake g++ make libgl1 libglx-mesa0 -y

cd /mnt/data
sudo curl https://raw.githubusercontent.com/Pelochus/ezrknpu/main/install.sh | sudo bash
```

##### Test run

```bash
GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/Pelochus/qwen-1_8B-rk3588 # Running git lfs pull after is usually better
cd qwen-1_8B-rk3588 && git lfs pull # Pull model
rkllm qwen-chat-1_8B.rkllm # Run!
```

##### Installation of Miniforge3

```bash
wget -c https://github.com/conda-forge/miniforge/releases/download/24.9.0-0/Miniforge3-24.9.0-0-Linux-aarch64.sh

chmod 777 Miniforge3-24.9.0-0-Linux-aarch64.sh

bash Miniforge3-24.9.0-0-Linux-aarch64.sh
```

##### Create RKLLM-Toolkit Conda Environment

```bash
source ~/miniforge3/bin/activate

conda create -n RKLLM-Toolkit python=3.8

#
# To activate this environment, use
#
#     $ conda activate RKLLM-Toolkit
#
# To deactivate an active environment, use
#
#     $ conda deactivate

conda activate RKLLM-Toolkit
```

##### Install RKLLM-Toolkit

```bash
pip3 install rkllm_toolkit-x.x.x-cp38-cp38-linux_x86_64.whl
```

##### Install OpenCL

Download the ARM Mali GPU blob from rockchip's repository and put it into /usr/lib/ as follows. And install the firmware for the GPU if not already installed.

```bash
cd /usr/lib && sudo wget https://github.com/JeffyCN/mirrors/raw/libmali/lib/aarch64-linux-gnu/libmali-valhall-g610-g6p0-x11-wayland-gbm.so
cd /lib/firmware && sudo wget https://github.com/JeffyCN/mirrors/raw/libmali/firmware/g610/mali_csffw.bin
```

Add the Mali GPU blob to the OpenCL ICD config file as follows;

```
sudo apt install mesa-opencl-icd clinfo
```

On Ubuntu, you may get not found errors, especially huawei links. Ignore them. It looks OK. Proceed with the followings;

```bash
sudo mkdir -p /etc/OpenCL/vendors
echo "/usr/lib/libmali-valhall-g610-g6p0-x11-wayland-gbm.so" | sudo tee /etc/OpenCL/vendors/mali.icd
```

Set the dependencies of the Mali OpenCL as follows;

```bash
sudo apt install libxcb-dri2-0 libxcb-dri3-0 libwayland-client0 libwayland-server0 libx11-xcb1
```

Now you can run "clinfo" to check whether OpenCL is working.

```bash
clinfo...
```

Check whether some dependencies are missing using ldd command as follows;

```
ldd /usr/lib/libmali-valhall-g610-g6p0-x11-wayland-gbm.so
```

Create Symbolic Link for libOpenCL.so

The directory "/usr/lib/aarch64-linux-gnu/" will have "libOpenCL.so.1.0.0". But no "libOpenCL.so" file. In this case, create a symbolic link as follows. You need to log into root account to create this, say, "su -";

```bash
cd /usr/lib/aarch64-linux-gnu/ && sudo ln -s libOpenCL.so.1.0.0 libOpenCL.so
```

Copying OpenCL "CL" Folder into "/usr/include"

```bash
cd ~/ && wget https://www.roselladb.com/download/CLv3.zip
unzip CLv3.zip
sudo cp -r CL /usr/include
sudo reboot
```
