Note that a pile of drivers don't seem to take implicit fencing into account, or at least don't call drm_atoimc_set_fence_for_plane(). Cc'ing relevant people, or at least some. Some drivers also look like they don't disable implicit fencing (e.g. amdgpu) because the explicit fences and implicit fences are handled by entirely independent code paths. I also wonder whether we shouldn't just make the recommended helpers the default ones, since a lot of drivers don't bother to handle the implicit fences at all it seems. The helpers won't blow up even for non-GEM drivers or GEM drivers which don't fill out the gem bo pointers in struct drm_framebuffer. v2: Comments from Eric.
