Also ensure your version is >= 22.3.0, as earlier versions had broken dri2 buffer exchange logic when dealing with overlay planes.
System logs reveal that i915 completely skips initialization, and devices under /dev/dri/ fail to appear.
Most modern Intel-based laptops and desktops use —GPUs built directly into the CPU. Unlike dedicated cards, these iGPUs share your system's RAM. Efficient memory management is the only thing standing between a smooth experience and a laggy mess. i915ovmfrom upd
The keyword "i915ovmfrom upd" appears to be related to the update process for OVMF firmware, specifically for Intel-based systems using the i915 driver. When updating OVMF firmware, the system may use a mechanism to validate and apply new firmware images. The "i915ovmfrom upd" string might indicate a specific update process or a flag used during the update procedure.
i915ovmfrom UPD is a kernel-level mechanism focused on transferring GPU virtual memory mappings between i915 VM contexts efficiently and safely—important for performance, correctness, and multi-context graphics workflows. Also ensure your version is >= 22
The following article breaks down the components of this technical query and how to manage the associated technologies. Understanding i915 Graphics and Virtual Machine Updates

This is where the open-source project comes into play. The name itself is a useful abbreviation:
: Enabling the GPU to handle video decoding and 3D rendering.
The ovm part of our keyword likely relates to —a technique to map guest physical addresses to host physical addresses in a nested virtualized environment (e.g., running Docker inside a KVM VM on an Intel host).
Modern enterprise setups require hardware-accelerated VMs to run media servers, automated UI testing, or remote desktop infrastructure. To achieve this without buying multiple physical GPUs, engineers split a single Intel iGPU among several Virtual Machines.
