DESCRIPTION

        nsc  is an Xorg driver for National Semiconductors GEODE processor fam‐
        ily.  It uses the DURANGO kit provided by National Semiconductor.   The
        driver  is  accelerated,  and provides support for the following frame‐
        buffer depths: 8, 16 and 24.
        The nsc driver supports GXLV (5530 companion chip), SC1200, SC1400  and
        GX2 (5535 companion chip).
        Please  refer  to xorg.conf(5) for general configuration details.  This
        section only covers configuration details specific to this driver.
 
        The driver will auto-detect the amount of video memory present for  all
        chips.  If  the  amount  of  memory is detected incorrectly, the actual
        amount of video memory should be specified with a VideoRam entry in the
        config file "Device" section.
 
        The following driver Options are supported:
 
        Option "SWCursor" "boolean"
               Enable or disable the SW cursor.  Default: off.
 
        Option "HWCursor" "boolean"
               Enable or disable the HW cursor.  Default: on.
 
        Option "NoAccel" "boolean"
               Disable   or  enable  acceleration.   Default:  acceleration  is
               enabled.
 
        Option "NoCompression" "boolean"
               Disable or enable compression.  Default: compression is enabled.
 
        Option "ShadowFB" "boolean"
               Enable or disable use of the shadow framebuffer layer.  Default:
               off.
 
        Option "Rotate" "CW"
               Rotate the display clockwise. This mode  is  unaccelerated,  and
               uses the Shadow Frame Buffer layer.  Default: no rotation.
 
        Option "Rotate" "CCW"
               Rotate the display counterclockwise. This mode is unaccelerated,
               and uses the Shadow Frame Buffer layer.  Default: no rotation.
 
        Option "FlatPanel" "boolean"
               This enables the FlatPanel display unit. The  FlatPanel  depends
               on  the  BIOS  to do the Panel h/w initialization.  In GX2 based
               platforms with TFT part Flatpanel is enabled, and on CRT part is
               disabled.  Default: off.
 
        Option "OSMImageBuffers" "integer"
               This sets the number of scanline buffers to be allocated in off‐
               screen memory for acceleration. This can take any value  0  will
               disable  the  allocation.  Disabled if cannot allocate requested
               scanline memory.  Default: 20.
 
        Option "ColorKey" "integer"
               This sets the default pixel value for the YUV video overlay key.
               Default: 0.

        Option "TV" "PAL-768x576"
               Selects  the PAL TV display mode 768x576 and the depth is forced
               to 16 bpp.  Default: no TV.
 
        Option "TV" "PAL-720x576"
               Selects the PAL TV display mode 720x576 and the depth is  forced
