Seems like they'd do alot better just: while (!pOverlay->VBlankActiveFunc(pSIS)); and hope they don't enter the blank while they're writing those registers. If they really need to synchronize something on the retrace, is it easy to put functions in DRI so that you can queue a request in the kernel? Regardless this driver is busted. :( -- Billy Biggs [EMAIL PROTECTED] _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
