本人只操作过单个rocm版本的情景，20240218 ubuntu 22.04.01

1，卸载原先的rocm

https://docs.amd.com/en/docs-5.1.3/deploy/linux/os-native/uninstall.html

# Uninstall single-version ROCm packages
sudo apt autoremove rocm-core

# Uninstall Kernel-mode Driver
sudo apt autoremove amdgpu-dkms

# remove apt source
sudo rm /etc/apt/sources.list.d/<rocm_repository-name>.list
sudo rm /etc/apt/sources.list.d/<amdgpu_repository-name>.list
sudo rm /etc/apt/sources.list.d/rocm.list
sudo rm /etc/apt/sources.list.d/amdgpu.list

sudo rm -rf /var/cache/apt/*
sudo apt-get clean all

sudo reboot

2，安装最新的rocm

https://rocm.docs.amd.com/projects/install-on-linux/en/latest/tutorial/quick-start.html#rocm-install-quick

sudo apt install "linux-headers-$(uname -r)" "linux-modules-extra-$(uname -r)"
# See prerequisites. Adding current user to Video and Render groups
sudo usermod -a -G render,video $LOGNAME
wget https://repo.radeon.com/amdgpu-install/6.0.2/ubuntu/jammy/amdgpu-install_6.0.60002-1_all.deb
sudo apt install ./amdgpu-install_6.0.60002-1_all.deb
sudo apt update
sudo apt install amdgpu-dkms
sudo apt install rocm
sudo reboot
sudo amdgpu-install --usecase=graphics,rocm
sudo reboot

3，安装依赖

Clang: ... 'cmath' file not found
找不到 #include_next <cmath>

sudo apt install libstdc++-12-dev

4，示例

4.1 amd官方示例

$ git clone --recursive  https://github.com/amd/rocm-examples.git
$ cd HIP-Basic/device_query
$ make
$ ./hip_device_query

  printf("\nR =\n");
  print_matrix(hA.data(), M, N, lda);
