And if our Grand Plans with configurability come true, then your test-harness will want to do that loading and setup itself anyway. With that there also shouldn't be any problems with fbcon, since presumably you already have that bound to the real gpu. So I think we're all fine here, for everyone. Now if you built-in vkms, that's a different thing. And for that I really think a "don't do that" is the right choice. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
