I meant really "3d blit". But you're wrong about the two tris - the code indeed used to do that, and indeed I got full-screen diagonal tearing with this. Currently it uses a rect or quad. (FYI, nouveau seems to use one big tri scissored to a quad for nv40, and a quad for nv50, though I didn't look to closely.) > So it isn't > just top to bottom, but two passes, once for each triangle.

No idea, but since you can wait for any vline I don't really see why you'd need to be able to wait for both falling and rising edge anyway. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
