I wonder if always reading FIFO_STAT before GUI_STAT would make a difference. The register reference says that the GUI_ACTIVE bit in GUI_STAT would be set if the FIFO is not empty, but all the sample code I recall looking at waits for idle by reading FIFO_STAT to make sure the last 16 slots are not filled, and _then_ reads GUI_STAT. It always seemed like overkill, but maybe reading FIFO_STAT somehow updates GUI_STAT. -- Leif Delgass http://www.retinalburn.net ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
