Hi, This patchset contains a new Linux* Kernel Driver for Intel® VPUs. VPU stands for Versatile Processing Unit and it is an AI inference accelerator integrated with Intel non-server CPUs starting from 14th generation. VPU enables efficient execution of Deep Learning applications like object detection, classification etc. Driver is part of gpu/drm subsystem because VPU is similar in operation to an integrated GPU. Reusing drm driver init, ioctl handling, gem and prime helpers and drm_mm allows to minimize code duplication in the kernel. The whole driver is licensed under GPL-2.0-only except for two headers imported from the firmware that are MIT licensed. User mode driver stack consists of Level Zero API driver and OpenVINO plugin. Both should be open-sourced by the end of Q4. The firmware for the VPU will be distributed as a closed source binary. I'm resending v3 patchset with correct Dave's email.

You have to add yourself to MAINTAINERS. I assume that there's a FOSS userspace available? Best regards Thomas
