    1 The diff file contains code to add overlay support for the ati video driver.  Note that only video files that have the '''YCbCr422''' format are handled by the overlay code.  RGB16 and RBG32 are not handled.  The x.org driver from which this code was adapted also did not handle RGB16 and RGB32;  thus, it appears the chips handled by the driver are not capable of handling those video formats, especially since ATI wrote most of the code in the x.org driver.
     1The diff file '''ATI_AddOverlayPatch.diff''' contains code to add overlay support for the ati video driver.  Note that only video files that have the '''YCbCr422''' format are handled by the overlay code.  RGB16 and RBG32 are not handled.  The x.org driver from which this code was adapted also did not handle RGB16 and RGB32;  thus, it appears the chips handled by the driver are not capable of handling those video formats, especially since ATI wrote most of the code in the x.org driver.

    33In addition, the code changes in the diff file also does some style cleanup in the files where overlay code was added.  Furthermore, some changes were also made to hopefully handle 64 bit addressing properly.  Most of the changes for 64 bit addressing are in the source file '''driver.cpp'''.
