This directory contains the sources for the accelerated Xpmac server
,which supports
	ATI Mach64, Rage128
	Matrox MGAxx64
	IxMicro TwinTurbo128
	C&T 6555x
and runs at 8/16/32 bpp(packed 24bpp is not supported). Most functions
are derived from XFree86 and adapted to PPC.

This sever will also work with acceleration under MkLinux if mmap
stuffs are properly intalled into the Mach kernel and the Linux server.


Changes from the original Xpmac:
 o HW acceleration support(of course:-)
 o Color map handling when no available video dirver is active.
 o Added following start up options:
    -fix4mb  Process 4MB WRAM bank boundary for Matrox MGA2x64.
	     Don't use when matroxfb is running.

    -tt128 Enable TwinTurbo128 acceleration when no TT128 video
           driver is found. Accelerator address is calculated from
	   the frame buffer address, when direct color map handling
	   is enabled.

    -mach64 Enable Mach64 acceleration when no ATI video driver
	    is found. Accelerator address is calculated from the
	    frame buffer address, when direct color map handling
	    is enabled.

    -ct6555 Enable C&T 6555x acceleration when no chips video driver
	    is found. Accelerator address is calculated from the
	    frame buffer address, when direct color map handling
	    is enabled.

    -novideodriver Same as -mach64

    -noaccel Disable all acceleration


Notes: 	The source is currently not well organized. Some clean up
	will be necessary.
