Hi,
I'd like to get comments on this before I polish it. This is a simple way to get something similar with vkms but it heavily reuse the code provided by virtio-gpu. Please feel free to give me any feedbacks or comments.
No.
First, what is wrong with vkms?
Second, if you really want something simple with the minimal set of drm features possible you can write a rather small but still self-contained driver when using all the drm helpers (shmem, simple display pipe) we have these days. Copy cirrus, strip it down: drop modesetting code, drop blit-from-shmem-to-vram code, drop pci probing. Maybe add module options for max/default video mode. Done.
What is the use case btw?
