FWIW, it's possible to avoid tearing between GPUs in a much less complicated
way than that, if the drivers for both GPUs use the ScreenRec::SyncSharedPixmap
hook. You can take a look at xf86-video-amdgpu/ati for an example. (The driver
of the displaying GPU also needs to separately prevent tearing of the scanout
process itself. xf86-video-amdgpu/ati do this by default for PRIME outputs)
