It seems that the new beta driver is causing the cuEGLStreamProducerConnect CUDA function to return the error 'operation not supported' (801). I’ve not yet upgraded to the 525 driver to test this myself. The issue is happening with the nvidia-vaapi-driver, on this line, which is odd because that co…

No, the direct backend is a potential work around for the issue, as it does not use EGLStreams. It doesn’t solve the issue that EGLStream with CUDA is broken as of the 525 release.

I have filed a bug 3893338 internally for tracking purpose. Can someone share precise repro steps so that I can try locally on my setup to reproduce issue.

I’ve whipped up a quick test case which reproduces the issue on my machine: //compile with gcc test.c -lEGL -lcuda #include <stdio.h> #include <cuda.h> #include <cudaEGL.h> #include <EGL/egl.h> static PFNEGLSTREAMIMAGECONSUMERCONNECTNVPROC eglStreamImageConsumerConnectNV; static PFNEGLCREATESTREAM…

@elFarto Thanks for sharing the sample code, I am able to reproduce issue locally. We will investigate on it and update.

525.78.01 driver released and the issue is still there.

We have root caused the issue successfully and fix will be incorporated in future released driver.

with future release you mean 525.85.05? greetings

530.30.02 beta driver released and the issue isn’t fixed.

I can confirm that driver version 525.105.17 does NOT have the fix incorporated: it still has the same bug.

One of the worst mistakes I’ve made was buying a GPU from NVIDIA, specifically the 3070. My desktop runs atrociously bad while the GPU is idling, and the CPU is at 100% usage. I’ve tried different distros and settings, but the problem remains. Even my laptop with an Intel iGPU runs better than my PC…

Do you know if this is included with driver 545? I am waiting on Manjaro to package it in order to test
