Hi Am 24.09.22 um 17:11 schrieb Jacek Lawrynowicz:Hi, This patchset contains a new Linux* Kernel Driver for Intel® VPUs.VPU stands for Versatile Processing Unit and it is an AI inference acceleratorintegrated 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 toan 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 importedfrom 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.

I assume that there's a FOSS userspace available?
Rereading the cover letter, it will be opensourced. I think DRM policy is that we first need an OSS userspace befor the kernel driver get's merged. Nevertheless it's now a good time to get the driver in shape.
I've finished looking trough the patchset and left comments on some of them. Best regards Thomas
