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

1,找一台nv kmd列表中支持的 GPU 的电脑,安装ubuntu22.04

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

2,重新编译安装Linux kernel

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

3, 安装 cuda sdk 12.3 但保留最后两步

按照nv官方步骤,先执行step1的安装

3.1 安装之前需要设置黑名单,官方指导

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

3.2 安装 cuda sdk step 1

操作链接:

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

4, 使用开源代码替代step2

4.1 下载编译 NV gpu 的开源 kmd

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

4.2 编译安装

make clean
make -j12
sudo make modules_install
sudo make install
sudo reboot

5,执行step 3 安装 cuda

sudo apt-get install -y cuda-drivers-545

测试:

$ nvidia-smi

$ ./vectorAdd

6,怎么验证这个kmd是从 源码安装的呢?

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:
