NAME
     rendition - Rendition video driver

     EndSection

DESCRIPTION
     rendition is an Xorg driver for Rendition/Micron based video
     cards.  The driver supports following framebuffer depths: 8,
     15 (Verite V1000 only), 16 and 24. Acceleration  and  multi-
     head  configurations  are not supported yet, but are work in
     progress.

SUPPORTED HARDWARE
     The rendition driver supports PCI and AGP video cards  based
     on the following Rendition/Micron chips:

     V1000       Verite V1000 based cards.

     V2100       Verite V2100 based  cards.  Diamond  Stealth  II
                 S220 is the only known such card.

     V2200       Verite V2200 based cards.

CONFIGURATION DETAILS
     Please  refer  to  xorg.conf(4)  for  general  configuration
     details.   This  section  only  covers configuration details
     specific to this driver.

     The driver auto-detects the chipset type, but the  following
     ChipSet names may optionally be specified in the config file
     "Device" section, and will override the auto-detection:

         "v1000", "v2x00".

     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"
          Disables use of the hardware cursor. Default:  use  HW-
          cursor.

     Option "OverclockMem" "boolean"

          Increases the Mem/Sys clock to 125MHz/60MHz from  stan-
          dard 110MHz/50MHz.  Default: Not overclocked.

     Option "DacSpeed" "MHz"
          Run the memory at a higher clock. Useful on some  cards
          with  display  glitches at higher resolutions. But adds
          the risk to damage the hardware. Use with caution.

     Option "FramebufferWC" "boolean"
          If writecombine is disabled in BIOS, and you  add  this
          option  in configuration file, then the driver will try
          to request writecombined  access  to  the  framebuffer.
          This  can drastically increase the performance on unac-
          celerated server. Requires that "MTRR"-support is  com-
          piled into the OS-kernel.  Default: Disabled for V1000,
          enabled for V2100/V2200.

     Option "NoDDC" "boolean"
          Disable probing of DDC-information from  your  monitor.
          This  information is not used yet and is only there for
          informational purposes. Safe to disable if you  experi-
          ence  problems  during  startup  of X-server.  Default:
          Probe DDC.

     Option "ShadowFB" "boolean"
          If this option is enabled, the driver  will  cause  the
          CPU  to  do  each drawing operation first into a shadow
          frame buffer in system virtual memory and then copy the
          result into video memory. If this option is not active,
          the CPU will draw directly into video memory.  Enabling
          this option is beneficial for those systems where read-
          ing from video memory is, on average, slower  than  the
          corresponding  read/modify/write  operation  in  system
          virtual memory.  This is normally the case for  PCI  or
          AGP  adapters,  and,  so,  this  option  is  enabled by
          default  unless  acceleration  is  enabled.    Default:
          Enabled unless acceleration is used.

     Option "Rotate" "CW"

     Option "Rotate" "CCW"
          Rotate the display clockwise or counterclockwise.  This
          mode is unaccelerated.  Default: no rotation.

     For the moment the driver defaults  to  not  request  write-
     combine  for  any  chipset  as there has been indications of
     problems with it. Use Option "MTRR" to let the driver  request
     write-combining of memory access on the video board.
