Do mediated devices work in Proxmox on kernel 6.17? Plex stopped utilising hardware acceleration (i915) in VM like it used to do in not so distant past...
I even tried in LXC (with all those cgroups entries) and also nothing... I have installed installed intel drivers in proxmox host on top adding kernel and modules options.
 
Intel GVT-g is a deprecated technology that provided mediated device passthrough for Intel iGPUs on 5th generation (Broadwell) through 10th generation (Comet Lake) processors. The gvt-linux project has been officially discontinued by Intel. Intel has ceased development and contributions including maintenance, bug fixes, new releases, or updates, and Intel no longer accepts patches to the project. GitHub The repo was archived in October 2024.
For Xe Architecture (Gen12) and newer, the SR-IOV feature is the intended replacement. So GVT-g (mediated devices) are effectively dead upstream, and the PVE kernels have been tracking upstream closely. This explains why it worked "not so long ago" — it broke somewhere in the 6.8 kernel era.
