Jetson Thor, before MIG

Hi, I am using Jetson Thor T-4000 of jetpack version 7.1 which supports Multi-Instance GPU(MIG).

I tried MIG like this.

(after booting, connected via ssh from local PC)
sudo su
nvidia-smi -i 0 -mig 1
nvidia-smi -i -0 -pm 1
nvidia-smi mig -cgi 0 -C

And I got Error like this.

”Unable to create a GPU instance on GPU 0 using profile 0: Unknown Error
Failed to create GPU instances: Unknown Error”

The response from sudo dmesg | grep -iE “NVRM|GSP|MIG” | tail -n 20

[ 0.000000] psci: MIGRATE_INFO_TYPE not supported.

It seems like I have to make the physical display ports of gpu disabled before trying MIG.

And the belows are the things I tried.

  1. modeset=0, cli env modifying
    echo "nvidia-drm modeset=0" | tee /etc/modeprobe.d/nvidia-drm.conf
    sudo update-initramfs -u
    sudo systemctl set-defaulr multi-user.agent
    sudo reboot
    –> still ‘Unknow’ error

  2. displaymodeselector
    ./displaymodeselector --gpumode compute --auto
    –> ends with “ERROR: No NVIDIA display adapters found.“

what should I do before trying MIG in Jetson Thor?

Hi,

The MIG is not yet supported.
Thanks.
