--- Comment #14 from Pierre Ossman <[EMAIL PROTECTED]> 2008-11-20 10:58:41 PST --- For reference, the nouveau driver does the same thing and it works just fine. The rendering is done through two triangles, not through a blit. So it isn't just top to bottom, but two passes, once for each triangle. I've been fiddling around a bit, and it seems like the chip is only able to trigger on the rising edge, nothing else. I can determine this by the fact that a) the tear occurs at random places between runs, indicating that it does not have a stable reference point, and b) a torture test does not get rate limited to the refresh rate. (a and b are of course giving stable results with the rising edge trigger) I've been unable to find documentation for this register, so I have no idea how this is supposed to work except for Alex' code. -- 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
