@ShCby As far as I know, intel hasn't officially supported SR-IOV in mainline kernels. So It makes sense that they won't test media-driver and compute-runtime with third-party modified DKMS in such use case.

The broken image seems to be caused by a mismatched DRM format modifier that used to describe the memory layout.
You can turn to https://github.com/intel/media-driver for help.
