--- Comment #44 from Felipe Contreras <[email protected]> 2009-02-15 03:52:57 PST --- Created an attachment (id=22960) --> (http://bugs.freedesktop.org/attachment.cgi?id=22960) Miminal patch. I tried to minimize the changes of this patch #22774 and I found something very weird. In my laptop the only place where waiting is needed is in RADEONDownloadFromScreenCP, but I decided to go further and see how many iterations where required. It turns out that 99.99% of the time only 1 iteration is needed (i == 0), in very rare occasions (one per session) 2 iterations are needed. So I tried to minimize even more and I found out that doing a single read seems to fix the issue almost completely. I'm attaching the patch, hopefully this would help track down the issue. -- 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
