Where is the userspace for this? Why is this not part of the general blending engine we expose through kms, and try to document in drm_blend.c? E.g. there's i915 background color patches too, but they haven't landed yet because there's not yet an open-source userspace for it. Or proper uabi documentation.
I'll drop this for now, and see later how to do it in a generic way.
But I'm not sure what you mean with userspace here. Do you mean that we should have a libdrm wrapper for all DRM properties?
No, some real thing like drm_hwcomposer or weston support or something similar that gives us a clear idea how this thing is supposed to work and how it fits into the overall blending equations kms compositors can expect from properly working drivers.
