Verify kernel-mode driver installation#

Use the following command to check the installation of the AMD GPU Driver (amdgpu):

sudo dkms status

Additional software for user space#

The AMD ROCm platform provides a comprehensive set of user space software components for GPU-accelerated computing. See the following resources:

AIS (AMD Infinity Storage)#

When the AMD GPU driver initializes AIS (AMD Infinity Storage), it registers the GPU’s VRAM with the P2PDMA kernel subsystem. This generates about 1GB of metadata for every 64GB of VRAM. This metadata is stored in the host’s DRAM.

If you don’t need AIS, you can reclaim this memory by disabling AIS from being initialized by the GPU driver.

To disable AIS until next reboot:

sudo modprobe -r amdgpu
sudo modprobe amdgpu ais_disabled=1

To disable AIS persistently across reboots:

sudo bash -c 'echo "options amdgpu ais_disabled=1" > /etc/modprobe.d/amdgpu-ais.conf'
sudo update-initramfs -c -k all
sudo systemctl reboot

To re-enable AIS until next reboot:

sudo modprobe -r amdgpu
sudo modprobe amdgpu ais_disabled=0

To re-enable AIS persistently across reboots:

sudo rm /etc/modprobe.d/amdgpu-ais.conf
sudo update-initramfs -c -k all
sudo systemctl reboot
