+ * Notify DRM's vblank event handler at VSTARTUP
+ *
+ * Unlike DCE hardware, we trigger the handler at VSTARTUP. at which:
+ * * We are close enough to VUPDATE - the point of no return for hw
+ * * We are in the fixed portion of variable front porch when vrr is enabled
+ * * We are before VUPDATE, where double-buffered vrr registers are swapped

+ * It is therefore the correct place to signal vblank, send user flip events,
+ * and update VRR.
