  • 31fccf7fe   [PATCH] gxt4500: Fix colormap and PLL setting, support GXT6000P ... Browse Code »

    This fixes some bugs in the gxt4500 framebuffer driver, and adds support
    for GXT6000P cards.

    First, I had the red and blue channels swapped in the colormap update code,
    resulting in penguins' noses and feet turning blue (though the penguins
    weren't actually shivering :).

    Secondly, the code that calculated the values to put in the PLL that
    generates the pixel clock wasn't observing some constraints that I wasn't
    originally aware of, but am now that I have some documentation on the chip.

    The GXT6000P is essentially identical from software's point of view, except
    for a different reference clock for the PLL, and the addition of a geometry
    engine (which this driver doesn't use).

  • a3d899839   [PATCH] Fbdev driver for IBM GXT4500P videocards ... Browse Code »

    This is an fbdev driver for the IBM GXT4500P display card found in some IBM
    System P (pSeries) machines. These cards have hardware 2D and 3D
    capabilities, but the driver does not use them; it just exports a dumb
    framebuffer.
