Does this not apply also to the pageflip / atomic completion event?
Both DRM_EVENT_VBLANK and DRM_EVENT_FLIP_COMPLETE use the struct drm_event_vblank, so yes. I'll mention these two events explicitly.
They do? Seems like I have been spoiled by the libdrm API that uses drmEventContext with different callbacks for these things.
Yeah, see drmHandleEvent [1] in libdrm.
