     EndSection

DESCRIPTION

     nsc is an XFree86 driver for National Semiconductors GEODE
     processor family. It uses the DURANGO kit provided by
     National Semiconductor. The driver is accelerated, and pro-
     vides support for the following framebuffer depths: 8, 16
     and 24.

SUPPORTED HARDWARE

     The nsc driver supports GXLV (5530 companion chip), SC1200,
     SC1400 and GX2 (5535 companion chip).

CONFIGURATION DETAILS

     Please refer to XF86Config(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 unac-
          celerated, and uses the Shadow Frame Buffer layer.
          Default: no rotation.

     Option "Rotate" "CCW"
          Rotate the display counterclockwise. This mode is unac-
          celerated, 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 Pnale 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 allo-
          cated in offscreen 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.

     The following Options are supported only on SC1200 based
     platforms:

     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 to 16 bpp. Default: no TV.

     Option "TV" "NTSC-720x480"
          Selects the NTSC TV display mode 720x480 and the depth
          is forced to 16 bpp. Default: no TV.

     Option "TV" "NTSC-640x480"
          Selects the NTSC TV display mode 640x480 and the depth
          is forced to 16 bpp. Default: no TV.

     Option "TV_Output" "COMPOSITE"
          The selected TV mode output is coded for Composite sig-
          nal. Default: no TV.

     Option "TV_Output" "SVIDEO"
          The selected TV mode output is coded for SVIDEO signal.

          Default: no TV.

     Option "TV_Output" "YUV"
          The selected TV mode output is coded for YUV signal.
          Default: no TV.

     Option "TV_Output" "SCART"
          The selected TV mode output is coded for SCART signal.
          Default: no TV.

     Option "TVOverscan" x:yy:ww:hh"
          This option will let only the viewable display area
          smaller to be able to view on TV. The parameters xx:
          X-offset, yy: Y-offset, ww: Viewable width, hh: View-
          able height. Default: no TV.
