Writing Kdrive DDX driver

[manisha salve]

Thanks Franco ,

One more query i have regarding Pixmap , Is pixmap nothing but Framebuffer
itself  ???
I will give the program flow below with function name and file name:
main ()             dix/main.c
    |
    |
    InitOutput ()     dix/main.c
           |
           |
       KdInitOutput()       hw/kdrive/src/kdrive.c
          |
          |
        KdAddScreen()     hw/kdrive/src/kdrive.c
         |
         |
       AddScreen()        hw/kdrive/src/kdrive.c
         |
         |
       KdScreenInit()     hw/kdrive/src/kdrive.c
         |
         |
       fbFinishScreenInit()   fb/fbscreen.c
         |
         |
       miScreenInit()    mi/miscrinit.c
          |
          |
       miScreenDevPrivateInit()  mi/miscrinit.c
    {
        In this  function , Framebuffer addr is assigned to
screen->devPrivate
        pScrInitParms->pbits = pbits;
        pScrInitParms->width = width;
       pScreen->devPrivate = (pointer)pScrInitParms;
   }


pScreen->CreateScreenResources()   dix/main.c
        |
        |
miCreateScreenResources     mi/miscrinit.c
       |
      |
CreatePixmap()
     |
     |
ModifyPixmapHeader()
{
   In this function , Pixmap->devPrivate.ptr = Framebuffer Addr;
  then , pScreen->devPrivate = Pixmap;

}
