NAME    [Toc]    [Back]

     pnozz - Weitek Power9100 accelerated frame buffer

SYNOPSIS    [Toc]    [Back]

     pnozz0 at sbus? slot ? offset ?
     wsdisplay* at pnozz?

DESCRIPTION    [Toc]    [Back]

     The pnozz is a color frame buffer  with  graphics  acceleration, embedded in
     the  Tadpole SPARCbook 3GS, 3GX, 3TX and 3XP laptops.  It is
based on the
     Weitek Power9100 video processor and an IBM RGB525 RAMDAC.

     The pnozz driver interfaces the frame buffer  with  the  wscons(4) console
     framework.   It  does not provide direct device driver entry
points but
     makes its functions available via the internal  wsdisplay(4)
interface.

     If the tctrl(4) device is also configured, the pnozz will be
powered down
     when the lid of the  laptop  is  closed  or  the  screen  is
blanked.

BUGS    [Toc]    [Back]

     There is currently no way to switch back and forth from  the
onboard display
  to  the  external  connector.   It  is not possible to
change resolutions
     or color depth.
