问题描述

我在配备 Intel Core i7-13620H 处理器的迷你电脑上安装了 Ubuntu 20.04，该处理器具有集成的 UHD Graphics GPU（Raptor Lake）。但是，系统似乎无法正确识别我的 GPU。在 Ubuntu 设置中，它显示llvmpipe (LLVM 12.0.0, 256 bits)为我的 UHD Graphics iGPU。

此外，当我运行 时clinfo，它输出Number of devices 0,表明我的 GPU 未被检测到。这个问题给我带来了麻烦，特别是在我需要使用 GPU 的 OpenVINO 项目中。

系统信息

  • Ubuntu 版本：20.04
  • 处理器：Intel Core i7-13620H
  • GPU：英特尔 UHD 显卡集成 GPU（Raptor Lake）
  • 内核版本：5.15.0-94-generic

尝试的方法

（1）我尝试使用以下命令安装驱动程序包（https://dgpu-docs.intel.com/driver/installation.html#install-steps)：

sudo apt install -y linux-headers-$(uname -r) flex bison intel-fw-gpu intel-i915-dkms xpu-smi

（2）我还尝试从存储库手动安装软件包https://github.com/intel/compute-runtime/releases。我尝试安装版本24.05.28454.6发布包：

wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.15985.7/intel-igc-core_1.0.15985.7_amd64.deb
wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.15985.7/intel-igc-opencl_1.0.15985.7_amd64.deb

wget https://github.com/intel/compute-runtime/releases/download/24.05.28454.6/libigdgmm12_22.3.11_amd64.deb

我仍在寻求有关如何解决此问题的建议。任何帮助都将不胜感激。谢谢！

以 root 身份安装 apt 源

sudo su
curl -fsSL https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB | sudo gpg --dearmor --output /usr/share/keyrings/intel-sw-products.gpg
echo "deb [signed-by=/usr/share/keyrings/intel-sw-products.gpg] https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/intel-oneapi.list
apt update

# Install oneapi
apt install intel-oneapi-runtime-opencl intel-basekit clinfo opencl-headers

# source environment variableif want single session opencl

source /opt/intel/oneapi/setvars.sh

# Optional : if you want for every bash session
echo "source /opt/intel/oneapi/setvars.sh" >> ~/.bashrc
