I was thinking of i915_vblank_pipe_set(). One problem though is that the X driver currently only ever calls this with pipes set to 0x0, 0x1 or 0x3, even when only pipe B is actually enabled. Wonder if it might be worth breaking compatibility with Mesa again for some of these cases... -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
