If you are a kernel developer and want to see i915ovmfrom upd in action:
The i915 is the open-source Linux kernel driver for Intel integrated and discrete graphics. While it is built into the Linux kernel, users often need to update it manually via to enable advanced features like SR-IOV . This allows a single physical GPU (pGPU) to be split into multiple virtual GPUs (vGPUs) for virtual machines. Key Update Procedures 1. Installing/Updating via DKMS
