[Why] Cursor updates must acquire the pipe control lock to prevent vupdate from triggering in the middle of cursor programming. On DCN1 the pipe control lock prevents pageflips from occurring. This means that a cursor update right before vupdate can delay a pending pageflip [How] If the time until the next vupdate is less than a conservative estimate of the cursor programming time, wait until the vupdate has passed before locking.
