But this part is confusing me. intel_crtc_get_vblank_counter() is only supposed to do drm_crtc_accurate_vblank_count() fallback when the hardware lacks a working frame counter, and that should only be the case for ancient gen2 or semi-ancient i965gm TV output, ilk_crtc_disable() is not the function we should be calling in either of those cases.
What hardware do you have?

Note, this is a dev box that is only connected to a KVM and I haven't connected to it outside of ssh in years.
