Emulator attached GPU but not use GPU at all

[Thai N Pham]

Hello,

I'm facing strange issue. Emulators connected GPU but these vms does not use GPU.

My GPU driver setup in host:

1./ sudo apt-get purge nvidia-*
2./ sudo add-apt-repository ppa:graphics-drivers/ppa
3./ sudo apt-get update
4./ sudo apt-get install nvidia-driver-535
5./ sudo reboot
.
.
.
6./ nvidia-smi (check nvidia driver installed)
7./ curl https://get.docker.com | sh \
  && sudo systemctl --now enable docker
8./ distribution=$(. /etc/os-release;echo $ID$VERSION_ID) \
      && curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
      && curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | \
            sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
            sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list
9./ sudo apt-get update
10./ sudo apt-get install -y nvidia-container-toolkit
11./ sudo nvidia-ctk runtime configure --runtime=docker
12./ sudo systemctl restart docker

My inside container setup

....
# Install required packages
RUN apt-get update \
    && apt-get install -y \
    vulkan-tools \
    vulkan-utils \
    libnvidia-gl-535
...

Trying to start container

i take focus on this log, it seem not correct, i tried to use "sdkmanager --update" but no help

The container started successfully, i see it listed in nvidia-smi on host

But it did not listed inside container...

I think it's problem to use GPU. How can i solve this problem to able to use GPU to gain higher performance ?

Thanks,
