NVIDIA Drivers required with nvidia-headless

[robballantyne]

Hello

I have created an image which would not have been possible without the work you have done here (and the gstreamer interface) - Amazing job.

I have discovered that EGL is only possible with /dev/dri exposed within the container unless the Nvidia drivers are installed in the same way as you do with the GLX variant.

I'm happy to submit a PR to add this on, but I'll be mostly giving your own code back to you. I wanted to check what you wanted first.

This is tricky and I must think about this... This image is specifically meant to specifically not install the drivers compared to GLX.

@dcommander Does EGLStreams with NVIDIA work with VirtualGL via EGL even without GBM (this is not about Wayland)? Because my previous experience is that I did not need /dev/dri when I used egl0 and such similar syntax.

VirtualGL doesn't technically use EGLStream. EGLStream is a specific mechanism for transferring rendered frames between APIs. VirtualGL uses EGL with the EGL_EXT_platform_device extension. That extension exposes all GPUs in the system as EGL devices, and VirtualGL can select a device either by its EGL device ID or by its DRI device path.

[dcommander]

(Also, VirtualGL does not explicitly require GBM. Open source GPU drivers may use GBM at a lower level, such as interfacing with DRI3, but nVidia's drivers do not.)

@robballantyne This means that I would need your eglinfo inside the container.

Thank you @dcommander

@robballantyne I would need your eglinfo output inside the container in order to proceed.

And fundamentally, do you have the NVIDIA container toolkit set up?

@ehfd sorry I'm slow on this. I'm away currently but I'll get you the info you need ASAP

[ehfd]

I think checking NVIDIA_DRIVER_CAPABILITIES includes graphics and display or is all is the first thing to do.
Then we can see the /opt/VirtualGL/bin/eglinfo -e and /opt/VirtualGL/bin/eglinfo egl outputs.

This isn't urgent, so take your time.

[robballantyne]

It appears that I was doing something wrong on previous testing because EGL is fine on your image without dri or drivers. It's also fine on mine without drivers - I have no way to replicate what I did. Sorry for the waste of time.

I have included the outputs you asked for anyway because there is a small diff when running with drivers. I don't know if it's important.

All tests run on 3090 without /dev/dri present

This is still a meaningful issue, because nodes with nvidia-headless will not have EGL libraries and will error out.
Let me think of ways.

[ehfd]

I think checking based on libEGL_nvidia.so.0 on whether the userspace driver should be installed or not would be a good choice.

[ehfd]

I confirm that the existence of libEGL_nvidia.so.0 and libGLX_nvidia.so.0 is important for Vulkan and OpenGL capabilities, and nvidia-headless does not provide these libraries.
