见面礼,动态查看gpu使用情况,每隔2秒钟自动执行一次 nvidia-smi
$ watch -n 2 nvidia-smi
列表见 github of the kmd source code。
因为 cuda sdk 12.3支持最高到 ubuntu 22.04,故
下载 ubuntu 22.04...iso
rufus 刷U盘
重启电脑,F2F8F10F12一起按
进入 setup,修改启动顺序,选U盘第一
一步步安装好,
reboot
修改apt 国内源
为编译Linux kernel 安装软件:
- sudo apt update
-
- sudo apt upgrade
-
- sudo apt install build-essential
sudo apt-get update && sudo apt-get install libncurses-dev && sudo apt-get install build-essential && sudo apt-get install flex bison && sudo apt-get install libssl-dev && sudo apt-get install binutils && sudo apt-get install libelf-dev && sudo apt-get install openssh-server && sudo apt-get install vim && sudo apt-get install bc && sudo apt-get install dwarves && sudo apt-get install zstd
- sudo apt-get update
- sudo apt-get install libssl-dev
- sudo apt-get install binutils
- sudo apt-get install libelf-dev
- sudo apt-get install dwarves
sudo apt install linux-source-6.5.0
- sudo apt install linux-source-6.5.0
- ls
- mkdir ex_kernel_linux_debug
- cd ex_kernel_linux_debug/
- ls
- cp /usr/src/linux-source-6.5.0.tar.bz2 ./
- tar -xvjf linux-source-6.5.0.tar.bz2
- cd linux-source-6.5.0/
-
-
-
- cp /boot/config-6.5.0-44-generic ./.config
- make oldconfig
编译 kernel :
$ make -j
安装 kernel :
- $ sudo make modules_install
- $ sudo make install
- $ sudo reboot
按照nv官方步骤,先执行step1的安装
https://docs.nvidia.com/cuda/cuda-installation-guide-linux/#removing-cuda-toolkit-and-driver
具体操作:
复制如下:
- 8.3.6. Ubuntu
-
- Create a file at /etc/modprobe.d/blacklist-nouveau.conf with the following contents:
-
- blacklist nouveau
- options nouveau modeset=0
-
- Regenerate the kernel initramfs:
-
- sudo update-initramfs -u

https://developer.nvidia.com/cuda-12-3-0-download-archive?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=22.04&target_type=deb_local
- wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin
-
- sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600
-
- wget https://developer.download.nvidia.com/compute/cuda/12.3.0/local_installers/cuda-repo-ubuntu2204-12-3-local_12.3.0-545.23.06-1_amd64.deb
-
- sudo dpkg -i cuda-repo-ubuntu2204-12-3-local_12.3.0-545.23.06-1_amd64.deb
-
- sudo cp /var/cuda-repo-ubuntu2204-12-3-local/cuda-*-keyring.gpg /usr/share/keyrings/
-
- sudo apt-get update
-
- sudo apt-get -y install cuda-toolkit-12-3
下载:
https://github.com/NVIDIA/open-gpu-kernel-modules
- git clone https://github.com/NVIDIA/open-gpu-kernel-modules.git
-
- cd open-gpu-kernel-modules
-
- git checkout 545.23.06
-
- git branch
有时候下载会失败,下载下来后做好备份。或者 fork 到自己的github 账号后再clone
- make clean
- make -j12
- sudo make modules_install
- sudo make install
- sudo reboot
sudo apt-get install -y cuda-drivers-545
测试:
$ nvidia-smi
$ ./vectorAdd
在开源代码中 加点printk等代码看看:
重新编译安装
$ make modules -j
$ make modules_install -j
重启电脑
$ sudo reboot
然后执行:
$ sudo dmesg
这名加载的是开源代码的ko文件。
运行APP:
